Oklahoma Sales Tax Economic Nexus Threshold (2026)

Updated 2026-06-08

If your Thresholds business sells $100,000 into Oklahoma in a calendar year, you have economic nexus and must register, collect, and remit Oklahoma sales tax.

Oklahoma's economic nexus threshold, in detail

The current Oklahoma threshold is $100,000, in effect since 2019-11-01.

What counts toward the threshold: gross sales of tangible personal property AND most services delivered to Oklahoma customers. Resale sales may count in some states. Marketplace-facilitated sales typically do NOT count. Check the state's specific definitions before computing.

Counting periods

Most states apply the threshold on a rolling 12-month basis — look at the prior 12 months as of the end of each month. Some states look at the prior calendar year specifically. Oklahoma's rule is stated in its regulations; your registration must begin no later than the first day of the month after you cross, unless the state allows a grace period.

Common threshold-tracking mistakes

Measuring by calendar year only, missing when a rolling 12-month window would have triggered earlier.
Including tax in “gross sales”. The threshold uses pre-tax revenue; double-counting tax in the threshold figure can prematurely trigger registration.
Forgetting that the threshold resets — falling below in a subsequent year doesn't automatically deregister you. You must request deregistration through the Oklahoma DOR.

Oklahoma nexus note

Oklahoma sales tax nexus and economic nexus threshold: any seller without Oklahoma physical presence that made more than $100,000 in taxable Oklahoma sales during the preceding or current calendar year must register with the Oklahoma Tax Commission and collect Oklahoma state and local sales tax on sales delivered or sourced to an Oklahoma address. Oklahoma uses a sales-only remote-seller threshold -- no transaction-count test. Oklahoma marketplace facilitators have a separate lower marketplace threshold: a facilitator with at least $10,000 of Oklahoma taxable sales during the immediately preceding 12 months must file an election with OTC to collect and remit or comply with statutory notice/reporting requirements.
