Economic nexus threshold

You must register and collect once your Oklahoma sales reach $100,000, measured over the preceding 12 months. There is no transaction-count threshold. Taxable sales; below threshold a notice-and-report regime may apply. Sales made through a marketplace facilitator do not count toward the remote seller's threshold — only your direct sales do.

Filing frequency

OkTAP assigns a filing frequency at registration based on expected tax liability and adjusts it over time. Frequencies used in Oklahoma: Monthly · Semi-annual.

Due dates

Returns are due on the 20th of the month following the period. When the due date falls on a weekend or holiday it moves to the next business day.

Late filing: 10% of tax due if not paid within 15 days, plus interest.

Marketplace facilitator rules

Since November 2019, marketplace facilitators (Amazon, eBay, Walmart, TikTok Shop) collect and remit Oklahoma tax on your marketplace sales. How Oklahoma treats them:

Who collects?Facilitatoron marketplace orders; you collect on Shopify / your own site.

Count toward nexus?Noonly your direct sales are tested against the remote-seller threshold.

Do you still file?YesYes — a registered seller still files, even for periods where all sales were through marketplaces (a zero or marketplace-only return).

How reported?DeductionDeduction if registered.

Direct salesYou collectShopify, your own site, invoices — you collect and remit on your return.

Marketplace treatment changes state by state and year by year — SalesTax50 separates marketplace and direct sales automatically, but confirm with Oklahoma Tax Commission when in doubt.

Filing portal & AutoFile

FAQ

Do I need a Oklahoma permit if I only sell on Amazon?

If you exceed the $100,000 threshold with your direct (non-marketplace) sales or have physical presence (including inventory in Oklahoma warehouses), yes — you must register even though Amazon collects for you.

What if I sell on Shopify and TikTok Shop?

TikTok Shop collects as a marketplace facilitator; Shopify does not. You collect on Shopify orders and report both streams on your OkTAP return — SalesTax50 separates them automatically.

Does SalesTax50 file Oklahoma returns automatically?

Yes — AutoFile prepares your Vendor Use Tax Return from imported sales; you approve every return before it is submitted, and a $99 one-time state setup configures your existing Oklahoma permit.
