Oklahoma, in brief.
What is the economic nexus threshold in Oklahoma?
$100,000 in sales, effective November 1, 2019. Taxable merchandise sales in the preceding or current calendar year. Once the threshold is crossed, remote sellers must register with the Oklahoma Tax Commission and begin collecting.
What is the sales tax rate in Oklahoma?
The state sales tax rate is 4.5%. City and county rates bring combined rates to ~9% in many areas.
Do marketplace facilitators collect Oklahoma sales tax?
Yes — marketplace facilitators have been required to collect since July 1, 2018. Direct (non-marketplace) sales remain the seller’s obligation.
How does a remote seller register for Oklahoma sales tax?
Register with the Oklahoma Tax Commission before collecting — a remote seller must register once it crosses the economic nexus threshold ($100,000 in sales). As a Streamlined Sales Tax member state, Oklahoma also accepts central registration through the SST system, which covers all member states in one application.
Does Oklahoma offer a voluntary disclosure agreement (VDA)?
Yes — the Oklahoma Tax Commission administers a voluntary disclosure program with a lookback of 36 months (3 years). Penalties are generally waived; interest is generally still due. An advisor can approach the state anonymously before disclosing the client’s identity.
