IMPORTANT: These Terms contain a binding arbitration agreement, jury trial waiver, and class-action waiver. Please read them carefully.

01Agreement

These Terms of Service ("Terms") constitute a binding agreement between you and SalesTax50 LLC, a Delaware limited liability company ("SalesTax50," "we," "us," or "our").

By creating an account, clicking to accept these Terms, accessing, or using salestax50.com, our software, integrations, reporting tools, filing services, AutoFile services, or related products and services (collectively, the "Service"), you agree to these Terms.

If you use the Service on behalf of a company, accounting firm, partnership, limited liability company, corporation, or other organization, you represent and warrant that you have authority to bind that organization to these Terms.

The Service is intended for business and commercial use, not primarily for personal, family, or household purposes.

02What SalesTax50 Does

SalesTax50 provides software and related services that may allow you to:

  • connect sales channels, marketplaces, payment processors, and other systems;
  • upload transaction data;
  • import and organize sales information;
  • summarize sales and sales tax information;
  • calculate or report sales tax by jurisdiction;
  • prepare state and local sales and use tax reports;
  • prepare sales and use tax returns; and
  • where AutoFile or another filing service is enabled, submit approved returns to applicable taxing authorities.

SalesTax50 prepares and files sales tax returns based on the data available through your account and specifically approved by you or your authorized administrator.

Unless expressly agreed otherwise in writing, SalesTax50 does not independently audit, verify, or certify the underlying sales data used to prepare a filing.

No return will be submitted without approval by the account owner or an authorized administrator, except where a separate written agreement expressly provides otherwise.

03Customer Responsibility for Data

You are responsible for the accuracy, completeness, classification, and timeliness of all information provided to, uploaded to, imported into, or approved through the Service.

This includes, without limitation:

  • gross sales;
  • taxable sales;
  • exempt sales;
  • refunds;
  • returns;
  • discounts;
  • shipping and handling charges;
  • marketplace sales;
  • sales tax collected;
  • product and service taxability;
  • customer addresses;
  • destination information;
  • exemption information;
  • resale transactions;
  • marketplace-facilitator transactions;
  • filing jurisdictions;
  • account numbers;
  • sales tax registrations;
  • filing frequencies;
  • bank information;
  • prior-period adjustments; and
  • any other data used to calculate or prepare a filing.

You must review your information before approving a filing.

04Third-Party and Sales Channel Data

SalesTax50 may obtain information from third-party services selected or authorized by you, including services such as Shopify, Amazon, eBay, marketplaces, Stripe, Square, payment processors, accounting platforms, and other ecommerce or sales systems.

Information received from these systems is treated as data supplied or authorized by you.

SalesTax50 does not control and is not responsible for the accuracy or completeness of third-party data.

SalesTax50 is not responsible for errors or omissions resulting from:

  • incorrect information supplied by Shopify or another sales channel;
  • missing transactions;
  • duplicate transactions;
  • incorrect transaction dates;
  • synchronization errors;
  • API failures;
  • expired authorization tokens;
  • platform outages;
  • incorrect tax coding;
  • incorrect product classifications;
  • incorrect marketplace classifications;
  • delayed refunds;
  • retroactive adjustments;
  • incomplete historical data;
  • third-party changes made after filing; or
  • any other error originating from a third-party platform.

05Connected Sales Channels

You are responsible for connecting all sales channels, stores, marketplaces, accounts, payment processors, and other transaction sources that should be included in your filings.

SalesTax50 has no obligation to identify or discover:

  • undisclosed sales channels;
  • additional Shopify stores;
  • marketplace accounts;
  • offline sales;
  • wholesale transactions;
  • sales outside connected systems; or
  • other revenue sources that you have not provided or connected.

If you operate multiple accounts or stores, you are responsible for ensuring that each applicable account is connected.

06Integration and Connection Maintenance

You are responsible for maintaining valid connections between the Service and your third-party platforms.

Connections may stop operating because of password changes, expired credentials, revoked authorization, API changes, security requirements, reauthentication requirements, third-party outages, or other technical circumstances.

You are responsible for promptly reconnecting an account when notified that a connection has failed or requires attention.

SalesTax50 is not responsible for missing or delayed information caused by an interrupted or invalid integration outside our reasonable control.

07No Accounting Reconciliation or Audit

Unless separately agreed in writing, SalesTax50 does not perform:

  • an audit;
  • attestation;
  • financial statement review;
  • bookkeeping review;
  • bank reconciliation;
  • 1099-K reconciliation;
  • merchant deposit reconciliation;
  • income tax reconciliation;
  • inventory reconciliation; or
  • independent verification of your sales records.

SalesTax50 is not required to determine whether transaction information agrees with your bank deposits, financial statements, accounting books, Forms 1099-K, income tax returns, inventory records, or other financial information.

08Product and Service Taxability

Unless you purchase a separate service expressly covering taxability analysis, you are responsible for determining the proper taxability of your products and services.

This includes determining whether an item is taxable, exempt, partially exempt, subject to a special rate, subject to a product-specific rule, or treated differently by different jurisdictions.

SalesTax50 may provide taxability tools or informational classifications, but such tools do not replace your responsibility to review and approve your tax treatment.

09Exemption and Resale Certificates

You are responsible for obtaining, maintaining, validating, and producing resale certificates, exemption certificates, direct-pay permits, and other documentation supporting exempt transactions.

Unless separately agreed in writing, SalesTax50 does not determine whether your exemption documentation is legally sufficient.

10Marketplace Facilitator Transactions

SalesTax50 may rely on data indicating that a marketplace facilitator collected, reported, or remitted tax on a transaction.

You are responsible for reviewing the marketplace classification of your transactions.

SalesTax50 is not responsible for a marketplace's failure to collect tax, calculate tax correctly, remit tax, classify a transaction correctly, report sales correctly, or accurately identify marketplace-facilitated transactions.

11Nexus and Filing Obligations

You are responsible for determining where you have a legal obligation to register, collect tax, file returns, remit tax, or maintain a sales tax account.

Any nexus dashboard, threshold alert, calculation, report, or other information provided through SalesTax50 is an informational tool based on data available to the Service and does not constitute a legal determination of nexus.

SalesTax50 may not have information concerning employees, owners, contractors, offices, warehouses, inventory, fulfillment centers, affiliates, trade shows, acquisitions, physical presence, related entities, or activities occurring outside connected sales channels.

You are responsible for notifying us of relevant circumstances that may affect your filing obligations.

12Registrations

SalesTax50 does not prepare, submit, amend, renew, or close sales tax registrations, seller's permits, or similar state or local tax accounts as part of the Service, unless SalesTax50 expressly states otherwise in a separate written agreement.

You are responsible for obtaining and maintaining all required registrations and permits before SalesTax50 begins filing returns for a jurisdiction, and for providing correct account numbers, filing frequencies, effective dates, credentials, and other registration information.

At your request, SalesTax50 may refer you to an affiliated CPA firm or other qualified tax professional that may be available to assist with sales tax registrations, seller's permits, account setup, registration corrections, filing-frequency issues, account closures, nexus analysis, or related state and local tax matters.

Any registration or professional service provided by an affiliated CPA firm or other tax professional is outside the SalesTax50 Service and is governed by a separate engagement between you and that provider. Separate fees may apply. SalesTax50 does not guarantee that a referred provider will accept the engagement, complete a registration by any particular date, or obtain any particular result from a taxing authority.

Where required by applicable law, SalesTax50 will disclose a material affiliation or financial relationship with a referred service provider.

13Account Modes and Authorized Administrators

SalesTax50 accounts may be self-managed or firm-managed.

Self-Managed

The business or taxpayer reviews and approves its own filings.

Firm-Managed

A CPA, accountant, bookkeeper, tax professional, or other authorized firm manages the account for its client.

An accounting firm using SalesTax50 on behalf of a client represents that it has appropriate authority to access the client's information, connect sales channels, manage the account, review filings, approve filings, and authorize submission.

SalesTax50 may rely on instructions and approvals provided by an authorized account administrator. SalesTax50 has no duty to resolve internal disputes between a business and its accountant, employee, owner, contractor, or other authorized user.

14Review and Approval of Returns

Before filing, SalesTax50 will make available information regarding the prepared return through the Service or another reasonable method.

By approving a return, you affirm that you have reviewed and approved the data and amounts used in the return, including the reported sales, taxable sales, exemptions, deductions, tax collected, tax due, filing period, and jurisdiction.

Your approval constitutes authorization for SalesTax50 to submit the return. SalesTax50 may reasonably rely upon that approval.

SalesTax50 is not responsible for an error in an approved filing resulting from customer data, third-party data, incorrect classifications, omitted transactions, incorrect registrations, incorrect instructions, or information that you failed to correct before approval.

15Data Cutoff

SalesTax50 may establish a data cutoff date or time for each filing.

Transactions, refunds, chargebacks, corrections, or other changes entered or received after the applicable cutoff may appear in a later filing, require manual adjustment, or require an amended return. SalesTax50 does not prepare or file amended returns; any required amendment must be handled by you, your tax preparer, or a referred tax professional under a separate engagement.

You are responsible for reviewing the data available as of the filing cutoff.

16Filing Deadlines and Customer Approval

You must provide complete information and approve each filing sufficiently before its applicable filing deadline.

SalesTax50 may establish an internal approval deadline earlier than the taxing authority's statutory deadline.

SalesTax50 is not responsible for a late filing, penalty, interest, lost discount, or other consequence resulting from late approval, failure to approve, incomplete data, missing credentials, late information, incorrect account information, missing authorization, unresolved account issues, changes requested after the cutoff, or another customer-caused delay.

17Tax Payments and Rejected Debits

SalesTax50 does not hold your sales tax funds.

Tax payments are made from bank accounts or payment methods designated by you and may be processed directly by the applicable taxing authority.

You are responsible for ensuring that bank information is accurate, sufficient funds are available, the account remains open, ACH debits are permitted, debit blocks are removed, appropriate taxing-authority company IDs are authorized where necessary, and payment limits permit the required debit.

SalesTax50 is not responsible for any rejected, blocked, reversed, returned, delayed, or unsuccessful tax debit or payment, including failures caused by insufficient funds, incorrect bank information, ACH debit blocks, closed accounts, bank restrictions, payment limits, fraud controls, banking-system failures, or taxing-authority processing errors.

Any resulting tax, penalty, interest, fee, or collection charge remains your responsibility.

18Underlying Tax Liability

The amount of tax legally owed by you remains your tax obligation.

Underlying sales or use tax legally due does not constitute damages caused by SalesTax50 merely because the amount is later assessed, billed, collected, or paid.

SalesTax50 does not assume your tax liability.

19Late and Delinquent Returns

Standard filing services are intended for current-period returns unless otherwise expressly agreed.

SalesTax50 is not responsible for returns already delinquent, unfiled prior periods, unpaid prior taxes, historical errors, existing penalties, existing interest, collection activity, or other compliance issues arising before complete information and authorization were provided to SalesTax50.

Late and delinquent filing services may require additional fees.

20Transition From Another Provider

If you transition to SalesTax50 from TaxJar, Avalara, another software provider, a CPA, an accountant, a bookkeeper, or an internal filing process, you are responsible for identifying the last filing period handled by the prior provider and the first filing period to be handled by SalesTax50.

SalesTax50 is not responsible for duplicate filings, omitted filings, overlapping filings, missed filing periods, inconsistent opening balances, or late filings resulting from unclear or inaccurate transition information.

21Prior-Period Information

SalesTax50 may rely on historical information provided by you or a prior provider, including prior returns, account numbers, filing frequencies, carryforward balances, credits, registrations, tax payments, and prior-period adjustments.

SalesTax50 is not responsible for errors carried forward from periods preceding our service.

22Amended Returns and Changed Information

SalesTax50 provides filing services for original sales tax returns only, unless otherwise expressly stated in writing. SalesTax50 does not prepare or file amended sales tax returns.

An amended return may be required if information changes or is later determined to be incorrect, including transactions added, removed, duplicated, or corrected after filing; retroactive refunds or chargebacks; revised product taxability or exemption information; marketplace or Shopify corrections; revised third-party data; prior-period filing errors; or taxing-authority adjustments.

SalesTax50 is not responsible for the need to amend a return or for tax, penalties, interest, fees, or other consequences arising from incorrect, incomplete, changed, or subsequently corrected customer or third-party information.

If an amended return is required, you are responsible for arranging preparation and filing through your own CPA, tax preparer, attorney, or other qualified professional. At your request, SalesTax50 may refer you to an affiliated CPA firm or other qualified tax professional that may be available to assist.

Any amended-return or related professional service is outside the SalesTax50 Service and is governed by a separate engagement between you and the applicable professional. Fees charged by that professional are separate from SalesTax50 subscription and filing fees.

SalesTax50 does not guarantee that any referred professional will accept the engagement, obtain acceptance of an amended return, secure a refund or credit, or obtain waiver of tax, penalties, or interest.

Amended-return services are not automatically included with an original filing, may require separate documentation, require customer approval, and may be subject to additional fees.

23Tax Authority Rejections

A taxing authority may reject or delay a return for reasons outside SalesTax50's control, including incorrect account information, inactive registrations, duplicate filings, incorrect filing frequency, invalid credentials, missing prior returns, agency system errors, authorization problems, rejected payments, or government processing issues.

Where reasonably practicable, SalesTax50 may notify you of a rejection and assist with resubmission.

SalesTax50 is not responsible for penalties or interest caused by matters outside our reasonable control or by inaccurate customer or third-party information.

24Filing Confirmations

A filing confirmation, acknowledgment, or transmission record confirms only the status shown by that record.

It does not guarantee that a taxing authority will permanently accept the filing, agree with the reported tax position, correctly apply a payment, refrain from later adjustment, refrain from audit, or waive penalties or interest.

25Tax Notices

You remain responsible for monitoring physical mail, email, state tax portals, government messages, and other communications from taxing authorities.

You must promptly provide SalesTax50 with any notice relating to a filing handled through the Service.

Unless separately engaged for notice-resolution services, SalesTax50 does not undertake to monitor government correspondence or respond to notices on your behalf.

If you fail to provide a notice promptly, SalesTax50 is not responsible for additional penalties, interest, missed appeal deadlines, or other consequences caused by the delay.

26Audits, Appeals, and Professional Representation

Standard SalesTax50 services do not include sales tax audit representation, audit defense, appeals, protests, administrative hearings, litigation, voluntary disclosure agreements, penalty-abatement requests, nexus legal opinions, notice-resolution services, amended returns, state registrations, or professional representation before a taxing authority.

At your request, SalesTax50 may refer you to an affiliated CPA firm or other qualified tax professional for services outside the SalesTax50 Service, including amended returns, state registrations, tax notices, audits, nexus analysis, voluntary disclosure matters, or other tax issues.

Any referred professional service is performed under a separate engagement with that provider and may involve separate fees. To the fullest extent permitted by law, SalesTax50 does not guarantee the availability, advice, work product, outcome, or result of any separately engaged professional service.

27No Penalty-Free Guarantee

SalesTax50 does not provide a penalty-free, interest-free, or audit-protection guarantee unless such a guarantee is expressly stated in a separate written agreement applicable to your account.

28SalesTax50 Processing Errors

If you believe SalesTax50 made an error in processing a filing, you must notify us promptly in writing and provide reasonable supporting documentation.

If we determine that an error resulted solely from SalesTax50's processing of complete, accurate, and timely information that you properly reviewed and approved, our obligation will be limited to commercially reasonable efforts to correct the affected filing, subject to these Terms and applicable law.

Nothing in this section creates a guarantee to reimburse taxes, penalties, or interest.

29Tax Authority Positions

Tax authorities may disagree with calculations, sourcing, nexus conclusions, product classifications, exemptions, marketplace treatment, deductions, or other tax positions.

Use of SalesTax50 does not guarantee that any taxing authority will agree with a particular tax treatment.

30Addresses and Jurisdiction Assignment

Sales tax calculations may depend on location information.

You are responsible for providing accurate billing addresses, shipping addresses, customer locations, store locations, warehouse locations, origin addresses, and destination information.

SalesTax50 is not responsible for an incorrect jurisdiction assignment caused by incomplete, inaccurate, or ambiguous location information.

31Rounding and Minor Differences

Tax authorities and third-party platforms may use different methods for rounding or aggregating transaction-level tax.

Reasonable differences caused solely by differing rounding methodologies do not constitute a SalesTax50 error.

32Zero Returns

A registered taxpayer may be required to file a return even when there are no taxable sales or no tax due.

You remain responsible for maintaining accurate filing obligations and registrations.

The absence of transactions in SalesTax50 does not necessarily mean no return is required.

33Cancellation Does Not Close Tax Accounts

Disconnecting a jurisdiction or cancelling SalesTax50 does not cancel your sales tax permit, close your government tax account, terminate your filing requirement, or eliminate outstanding tax obligations.

You remain responsible for closing registrations directly with the applicable authority where appropriate.

34Authorizations

You authorize SalesTax50 to access connected platforms, retrieve authorized data, process transactions, prepare reports, prepare returns, access government systems where authorized, transmit approved returns, and retain filing records.

You agree to execute required powers of attorney, e-file authorizations, portal authorizations, or similar documents where necessary.

35No Tax, Legal, Accounting, or Professional Advice

Unless SalesTax50 LLC separately enters into a written professional-services engagement with you, use of the Service does not create an accountant-client relationship, attorney-client relationship, fiduciary relationship, tax advisory relationship, or other professional-services relationship.

Information supplied through the Service is general information and is not individualized tax, legal, or accounting advice.

You should consult your own professional advisors where appropriate.

A referral to an affiliated CPA firm or other tax professional does not by itself create a professional-services relationship with SalesTax50 LLC. Any such professional relationship arises only under the separate engagement, if any, between you and the referred provider.

36Account Security

You are responsible for maintaining account credentials, maintaining accurate contact information, controlling authorized users, removing unauthorized users, and promptly reporting suspected unauthorized access.

You are responsible for activities performed by authorized users through your account.

37Electronic Communications and Notices

You consent to receive Service-related notices electronically.

SalesTax50 may provide notices through email, account dashboard, in-app notification, or another reasonable electronic method.

This may include notices concerning filing readiness, filing deadlines, approval deadlines, integration failures, payment problems, return rejections, and account issues.

You are responsible for keeping your contact information current and monitoring these communications.

38Fees

Paid plans are billed according to the pricing, subscription tier, order form, or service agreement applicable to the applicable business account at the time the charge is incurred. Pricing displayed on the SalesTax50 website or in the Service is incorporated into these Terms for billing purposes, but SalesTax50 may change future pricing upon reasonable notice as permitted by law.

Subscription tiers may be based in part on transaction volume. Unless a written order form states otherwise, transaction volume is measured separately for each business using the Service and is not aggregated across businesses merely because they are managed through the same user login, accounting-firm dashboard, or administrative account.

For pricing purposes, a transaction may include a sale, order, refund, return, cancellation, adjustment, exchange, marketplace transaction, or other transaction record imported, uploaded, processed, or otherwise used by the Service. SalesTax50 may use reasonable counting and deduplication methods to determine transaction volume and the applicable subscription tier.

If a business exceeds the transaction limit of its subscription tier, SalesTax50 may require that business to move to the next applicable tier, charge the price applicable to the appropriate tier for future billing periods, limit or delay nonessential processing until the account is upgraded, or contact the customer to arrange appropriate pricing. SalesTax50 will not impose a retroactive volume charge unless disclosed in the applicable pricing terms or agreed in writing.

A plan described as having no transaction overage fees does not create an unlimited-capacity or unlimited-resource commitment. Standard SalesTax50 plans are intended for ordinary commercial use within the transaction volumes, integrations, processing patterns, and technical requirements reasonably contemplated for those plans. All plans remain subject to reasonable-use, technical, storage, security, API, integration, and operational limits. If SalesTax50 reasonably determines that a Business's usage is unusually large, technically complex, materially burdensome, abusive, or substantially exceeds normal usage for the applicable plan, SalesTax50 may require that Business to transition to an Enterprise or custom-priced plan. Relevant factors may include transaction volume, historical dataset size, synchronization frequency, API usage, unusually large imports or exports, repeated historical recalculations, number or complexity of integrations, storage requirements, processing or database load, unusual filing complexity, or other usage that materially increases the cost or technical burden of providing the Service. SalesTax50 will provide reasonable advance notice before applying Enterprise or custom pricing, except where immediate limitations, suspension, or other action is reasonably necessary to protect the security, stability, integrity, or availability of the Service. If the Customer does not accept the proposed Enterprise or custom pricing, the Customer may discontinue the affected Service before the new pricing takes effect, and SalesTax50 may thereafter limit, suspend, or discontinue the affected high-volume or non-standard functionality. SalesTax50 will not impose retroactive Enterprise or custom pricing for prior periods unless otherwise agreed in writing.

One user login may be permitted to manage multiple businesses, but each business is a separate subscription for pricing, transaction-volume measurement, AutoFile charges, state setup fees, filing approvals, and account administration unless SalesTax50 agrees otherwise in writing.

AutoFile charges are assessed per separately prepared or submitted return or filing obligation, as stated in the applicable pricing. A required zero-dollar return may count as an AutoFile return. Separately submitted state, local, home-rule, specialty, or other returns may each count as separate filings. Non-standard returns or jurisdictions may require separate pricing disclosed before the applicable service is performed.

SalesTax50 may charge a one-time AutoFile State Setup fee for each state or jurisdiction configured for filing. AutoFile State Setup is limited to configuring an existing customer tax account for use with the Service and is not a state registration, seller's permit application, tax-account registration, or professional tax-advisory service.

Additional SalesTax50 fees may apply to AutoFile, additional jurisdictions, late returns, prior-period filings expressly accepted by SalesTax50, special projects, non-standard processing, and other services expressly offered by SalesTax50. Amended returns, new state registrations, tax notices, audits, voluntary disclosure agreements, nexus consulting, and other professional services referred to an affiliated CPA firm or other tax professional are outside the SalesTax50 Service and are governed by a separate engagement and separate fees charged by that provider.

Prepaid filing credits, promotional credits, discounts, coupons, or other pricing incentives are governed by the terms presented when purchased or issued and may be subject to expiration, plan eligibility, non-refundability, non-transferability, and active-subscription requirements. Unless expressly stated otherwise, discounts do not combine.

Sales tax, penalties, interest, registration charges, government fees, bank fees, payment-processing charges, and amounts owed to third-party professionals are separate from SalesTax50 service fees.

Unless required by law or expressly agreed otherwise, SalesTax50 subscription fees, setup fees, filing fees, and prepaid credits are non-refundable once earned, used, or the applicable setup or filing work has begun.

39Failed Payments and Chargebacks

If SalesTax50 subscription or filing fees are unpaid, reversed, disputed, charged back, or otherwise not successfully collected, SalesTax50 may suspend future services or account access.

40Acceptable Use

You may not:

  • access another customer's data without authorization;
  • circumvent security controls;
  • reverse engineer the Service except where legally permitted;
  • scrape the Service without written authorization;
  • introduce malicious code;
  • interfere with the Service;
  • resell the Service without authorization;
  • submit data you have no legal right to use;
  • use the Service for fraud; or
  • use the Service in violation of law.

41Ownership

SalesTax50 LLC owns and operates the Service, including its software, code, algorithms, interfaces, databases, designs, documentation, trademarks, trade names, content, and other intellectual property, except for customer data and third-party materials.

You retain ownership of your data.

You grant SalesTax50 a limited license to access, import, copy, normalize, process, transmit, calculate, organize, store, archive, and otherwise use your data as reasonably necessary to provide, maintain, secure, support, and improve the Service.

42Confidentiality

Each party may receive confidential or proprietary information belonging to the other.

Each party agrees to use reasonable measures to protect confidential information and to use it only for purposes relating to the Service.

Confidential information does not include information that is publicly available without breach, was already lawfully known, is independently developed without use of confidential information, or is lawfully obtained from another source.

SalesTax50 may disclose information to service providers and subprocessors where reasonably necessary to operate the Service, subject to appropriate obligations.

Information may also be disclosed when required by law, subpoena, court order, or governmental request.

43Privacy and Security

SalesTax50 will maintain commercially reasonable safeguards designed to protect information processed through the Service.

However, no internet transmission, software system, cloud environment, third-party integration, or electronic storage method can be guaranteed to be completely secure.

Use of personal information is also governed by the Privacy and Data Protection Policies incorporated into and included below as part of these Terms.

44Third-Party Services

SalesTax50 depends on third-party systems and services that we do not control.

We do not guarantee the availability, continued operation, accuracy, or compatibility of any third-party service.

Changes or outages affecting APIs, ecommerce systems, payment processors, cloud infrastructure, banks, government portals, or other external services may affect SalesTax50's ability to perform the Service.

45Changes in Tax Law and Government Procedures

Tax laws, rates, forms, filing procedures, thresholds, agency systems, and administrative guidance may change.

SalesTax50 may modify calculations, reports, workflows, or functionality in response to changes in law, government guidance, or technology.

SalesTax50 does not guarantee that government guidance or systems will always be complete, consistent, available, or issued before a filing deadline.

46Beta and Experimental Features

Beta, preview, experimental, early-access, automated, or artificial-intelligence-assisted features may be incomplete or changed at any time.

Such features are provided without service-level commitments unless expressly agreed otherwise.

Automated outputs may contain errors and should be reviewed before being relied upon for a tax filing or other material decision.

47No Service-Level Guarantee

Unless a separate written service-level agreement expressly provides otherwise, SalesTax50 does not guarantee uninterrupted availability, any specific uptime percentage, response time, processing time, filing turnaround time, or uninterrupted third-party integrations.

48Right to Decline or Suspend a Filing

SalesTax50 may decline, suspend, or delay a filing if we reasonably believe information is incomplete, information is inconsistent, required authorization is missing, a filing may be unlawful, instructions appear fraudulent, required systems are unavailable, payment information is invalid, or proceeding could reasonably result in an inaccurate or unauthorized filing.

49Record Retention

SalesTax50 may retain returns, approval records, filing data, transmission records, confirmation records, account activity, and related audit-trail information as reasonably necessary for legal, operational, security, compliance, dispute-resolution, and recordkeeping purposes.

You remain responsible for maintaining your own tax and accounting records.

50Termination

You may cancel your subscription according to applicable billing terms.

SalesTax50 may suspend or terminate an account for failure to pay, violation of these Terms, fraud, security concerns, unlawful activity, abuse of government credentials, or circumstances creating unreasonable legal or operational risk.

After termination, available filing records and reports may remain accessible for up to 30 days, after which SalesTax50 may delete or de-identify information subject to applicable retention requirements.

Cancellation does not affect previously incurred obligations.

SALESTAX50 DOES NOT WARRANT THAT CUSTOMER DATA WILL BE ACCURATE; THIRD-PARTY DATA WILL BE ACCURATE; ALL TRANSACTIONS WILL BE IMPORTED; THIRD-PARTY SYSTEMS WILL REMAIN AVAILABLE; GOVERNMENT PORTALS WILL BE AVAILABLE; A RETURN WILL BE ACCEPTED; A TAX PAYMENT WILL BE SUCCESSFULLY DEBITED; A TAX AUTHORITY WILL ACCEPT A PARTICULAR TAX POSITION; OR USE OF THE SERVICE WILL PREVENT AN AUDIT, ASSESSMENT, PENALTY, OR INTEREST.

52Limitation of Liability

TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, SALESTAX50 LLC AND ITS MEMBERS, MANAGERS, AFFILIATES, CONTRACTORS, AGENTS, AND REPRESENTATIVES WILL NOT BE LIABLE FOR INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, EXEMPLARY, OR PUNITIVE DAMAGES, INCLUDING LOST PROFITS, LOST REVENUE, LOSS OF BUSINESS, LOSS OF DATA, BUSINESS INTERRUPTION, OR LOSS OF GOODWILL.

Except to the extent liability cannot legally be excluded, SalesTax50 will not be liable for underlying sales or use tax, uncollected tax, tax assessments, penalties, interest, collection costs, late-filing charges, late-payment charges, customer-data errors, third-party-data errors, Shopify or marketplace errors, missing or duplicate transactions, late customer approval, incomplete information, failed tax payments, rejected ACH debits, insufficient funds, government portal failures, filing rejections resulting from customer or third-party information, prior compliance problems, tax liabilities arising before SalesTax50's engagement, or the need for or consequences of amended returns required because data was inaccurate, incomplete, changed, or subsequently corrected. SalesTax50 does not prepare or file amended returns.

TO THE MAXIMUM EXTENT PERMITTED BY LAW, SALESTAX50 LLC'S TOTAL AGGREGATE LIABILITY FOR ALL CLAIMS ARISING OUT OF OR RELATING TO THE SERVICE OR THESE TERMS WILL NOT EXCEED THE GREATER OF (A) $500 OR (B) THE TOTAL FEES ACTUALLY PAID TO SALESTAX50 LLC BY YOU DURING THE TWELVE MONTHS IMMEDIATELY PRECEDING THE EVENT GIVING RISE TO THE CLAIM.

The limitations in these Terms apply regardless of the theory of liability and even if a remedy fails of its essential purpose, except where applicable law prohibits such limitation.

53Time Limit for Claims

To the fullest extent permitted by applicable law, any claim arising out of or relating to the Service or these Terms must be asserted within one year after the claimant knew or reasonably should have known of the facts giving rise to the claim.

Claims not asserted within that period are permanently barred to the extent permitted by law.

54Indemnification

To the extent permitted by law, you agree to defend, indemnify, and hold harmless SalesTax50 LLC and its members, managers, affiliates, contractors, agents, and representatives from third-party claims, liabilities, damages, losses, penalties, costs, and reasonable attorneys' fees arising from your data, inaccurate or incomplete information, third-party information connected at your direction, your tax obligations, your failure to collect or remit tax, unauthorized use of the Service, your violation of these Terms, your violation of law, or your infringement of third-party rights.

This provision does not apply to the extent prohibited by law.

55Force Majeure

SalesTax50 will not be responsible for a failure or delay caused by circumstances beyond its reasonable control, including acts of government, taxing-authority outages, natural disasters, fire, flood, earthquake, severe weather, war, terrorism, civil disturbance, labor disruption, cyberattack, widespread internet failure, cloud provider outage, telecommunications failure, banking interruption, third-party API failure, or similar events beyond our reasonable control.

Dispute Resolution

56Informal Dispute Resolution

Before commencing arbitration or litigation, the complaining party must send written notice describing the identity of the claimant, the relevant account, the factual basis of the dispute, the amount or relief requested, and contact information for the claimant.

Notices to SalesTax50 must be sent to support@salestax50.com.

The parties will attempt in good faith to resolve the dispute for at least 30 days after receipt of the notice.

57Binding Arbitration

PLEASE READ THIS SECTION CAREFULLY. IT AFFECTS YOUR RIGHT TO GO TO COURT.

Except for disputes expressly excluded below, you and SalesTax50 LLC agree that every dispute, claim, or controversy arising out of or relating to these Terms, your account, the Service, a filing, a payment, a subscription, any representation concerning the Service, or the relationship between you and SalesTax50 will be resolved through final and binding arbitration on an individual basis rather than in court.

The arbitration agreement is governed by the Federal Arbitration Act.

Arbitration will be administered by the American Arbitration Association ("AAA") under its applicable Commercial Arbitration Rules then in effect. If AAA determines that another set of AAA rules is legally required to apply to a particular dispute, those rules will apply to the extent required.

The arbitration will be conducted by a single neutral arbitrator. Judgment on the award may be entered in any court having jurisdiction.

58Authority of Arbitrator

Except as otherwise expressly provided in these Terms, the arbitrator will determine disputes concerning interpretation, applicability, enforceability, scope, and formation of this arbitration agreement.

However, a court of competent jurisdiction, rather than the arbitrator, will determine any dispute concerning the enforceability of the Class Action Waiver below.

59Class, Collective, and Representative Action Waiver

YOU AND SALESTAX50 LLC AGREE THAT EACH PARTY MAY ASSERT CLAIMS AGAINST THE OTHER ONLY IN AN INDIVIDUAL CAPACITY.

TO THE MAXIMUM EXTENT PERMITTED BY LAW: NO CLASS ACTION MAY BE BROUGHT; NO COLLECTIVE ACTION MAY BE BROUGHT; NO REPRESENTATIVE ACTION MAY BE BROUGHT; NO PRIVATE ATTORNEY GENERAL ACTION MAY BE BROUGHT ON BEHALF OF OTHERS; AND NO ARBITRATOR MAY CONSOLIDATE THE CLAIMS OF UNRELATED CUSTOMERS EXCEPT AS REQUIRED UNDER APPLICABLE AAA MASS ARBITRATION PROCEDURES.

YOU AND SALESTAX50 EXPRESSLY WAIVE THE RIGHT TO PARTICIPATE IN A CLASS, COLLECTIVE, CONSOLIDATED, OR REPRESENTATIVE PROCEEDING TO THE FULLEST EXTENT PERMITTED BY LAW.

60Mass Arbitration

If multiple substantially similar individual arbitration demands involving SalesTax50 qualify for administration under AAA's applicable Mass Arbitration Supplementary Rules, those rules and the applicable AAA mass-arbitration fee schedule will govern.

The filing of related individual claims does not convert those claims into a class action or authorize class-wide relief.

61Jury Trial Waiver

TO THE FULLEST EXTENT PERMITTED BY LAW, YOU AND SALESTAX50 LLC EACH WAIVE THE RIGHT TO A TRIAL BY JURY FOR ANY DISPUTE THAT IS PERMITTED TO PROCEED IN COURT.

62Exceptions to Arbitration

Either party may bring an eligible individual claim in small claims court, seek temporary emergency relief necessary to prevent immediate unauthorized access or cybersecurity harm, or bring a claim relating primarily to ownership, infringement, or misappropriation of intellectual property in a court of competent jurisdiction.

Nothing prevents a party from communicating with a governmental agency where permitted by law.

63Arbitration Costs

Arbitration fees will be allocated according to the applicable AAA rules and applicable law.

SalesTax50 will pay fees that applicable law or the governing AAA rules require SalesTax50 to pay.

Each party otherwise bears its own attorneys' fees and expenses unless applicable law or the arbitrator permits an award of such fees.

64Governing Law

These Terms and disputes arising out of or relating to them are governed by the laws of the State of Delaware, without regard to conflict-of-laws principles, except that the Federal Arbitration Act governs the arbitration provisions.

If applicable law requires application of another jurisdiction's non-waivable law to a particular issue, that law will apply only to the extent legally required.

65Venue for Non-Arbitrable Disputes

For disputes that are not subject to arbitration, and except where applicable law requires otherwise, the parties consent to the exclusive jurisdiction of the appropriate state or federal courts located in the State of Delaware.

Each party waives objections based on improper venue or inconvenient forum to the fullest extent permitted by law.

66Arbitration Severability

If a portion of the arbitration agreement is determined to be invalid or unenforceable, that portion will be severed and the remainder will continue in effect to the fullest extent permitted by law.

If a court determines that the prohibition against class arbitration itself cannot be enforced and that a class arbitration must be permitted, then the arbitration agreement will not apply to that class proceeding unless SalesTax50 expressly agrees otherwise.

General Provisions

67Changes to These Terms

SalesTax50 may modify these Terms from time to time.

Material changes will be communicated by email, through the Service, or through another reasonable method before they take effect where required.

Continued use of the Service after the effective date constitutes acceptance of the updated Terms.

68Assignment

You may not assign these Terms without SalesTax50's prior written consent.

SalesTax50 may assign these Terms in connection with a merger, acquisition, financing, reorganization, sale of substantially all assets, or transfer of the Service or related business.

Unless expressly stated otherwise, no accountant, advisor, owner, employee, customer, investor, affiliate, or other person is a third-party beneficiary.

70Severability

If any provision of these Terms is held invalid or unenforceable, the remaining provisions remain in effect.

An invalid provision will be enforced to the maximum extent legally permitted where possible.

71No Waiver

Failure to enforce a provision of these Terms does not waive that provision or any other right.

72Entire Agreement
