Taxes

Medical

Oklahoma has a 7 percent excise tax on medical marijuana on top of the state's sales tax.

Oklahoma has a SALES tax exemption for veterans who are 100% disabled. They are provided a tax exemption card from the Oklahoma Tax Commission and they can present it at any retailer. The exemption applies to sales tax only; the 7% excise tax may still be collected.

Delivery

Home delivery prohibitedOklahoma currently prohibits home delivery.

Things to Note

Although a monthly reporting requirement remains in the OMMA ruleset (OAC 442:10-5-6), OMMA guidance has clarified that dispensaries integrated with Metrc no longer need to file separate monthly reports—real-time tracking through the state inventory system satisfies the requirement.

State Resources

The OMMA hosts a variety of helpful resources including FAQs and all rules and regulations.
