## Key Takeaways

Oklahoma's state sales tax rate is 4.5%, with local city and county taxes bringing combined rates to around 9% or more in some areas [1]. You have economic nexus once sales into Oklahoma exceed $100,000 in the current or prior calendar year, with no transaction-count trigger [2]. SaaS and electronically delivered digital products are not taxable, and the state grocery tax was eliminated to 0% effective August 29, 2024, though local taxes on food still apply [1][3]. Protest an assessment within 60 days [5].

## Registration or Nexus Threshold

Oklahoma economic nexus applies once your sales into the state exceed $100,000 in the current or prior calendar year. There is no transaction-count trigger. Physical presence creates nexus immediately.

## Marketplace Facilitator Law

Oklahoma applies a marketplace-facilitator election threshold of at least $10,000 in aggregate taxable Oklahoma sales during the immediately preceding 12-month period — a separate, lower figure than the $100,000 economic-nexus threshold that applies to a remote seller's own direct sales. Once over that threshold, a facilitator must either register and collect and remit Oklahoma sales tax (if Oklahoma-located) or vendor use tax (if out-of-state), or instead comply with the notice-and-reporting requirements of 68 O.S. § 1393. When a facilitator collects and remits on a seller's behalf, the marketplace seller is not required to separately collect tax on those sales, and an Oklahoma Tax Commission letter ruling states that facilitator-collected platform sales are excluded from the seller's own $100,000 economic-nexus calculation, while sales the facilitator does not collect on remain included.[8]

## Filing Frequency & Deadlines

Oklahoma assigns monthly or semiannual filing based on tax volume. Returns are due the 20th of the month following the reporting period.

#### Exemptions

Oklahoma eliminated its state sales tax on groceries in 2024, so food is exempt from the state rate (local taxes may still apply). Prescription drugs are exempt. SaaS and electronically delivered software are not subject to Oklahoma sales tax.

## Resale & Exemption Certificates

Oklahoma sellers buy inventory for resale tax-free using their sales tax permit and document exempt sales under the Oklahoma Tax Commission's vendor rules [4]. Sales tax permits are valid for three years and renew automatically unless revoked [1].

## Penalties

Late filing or payment carries a penalty of 10% of the tax due, plus interest from the due date until the balance is paid.

## Audits & Appeals

You must file a written protest, using Form L-25, within 60 days of a proposed assessment [5]. Miss the 60-day window and the Commission loses jurisdiction, so the assessment becomes final [5].
