Product Categories

Taxable: Tangible personal property, most retail goods, prepared food.

Exempt: Prescription drugs, most groceries (food for home consumption is exempt from the state rate), qualifying agricultural inputs, manufacturing equipment.

Grocery exemption: Oklahoma exempts most food and food ingredients for home consumption from the 4.5% state rate. Local jurisdictions may still tax groceries.

Digital Goods and SaaS

Oklahoma does not tax SaaS or most digital goods. The Oklahoma Tax Commission has held that software delivered electronically and accessed remotely is generally not subject to sales tax as tangible personal property.

• SaaS — not taxable; Oklahoma has not extended sales tax to remote software access
• Downloaded software — Oklahoma has taxed prewritten software on physical media; treatment of electronic downloads is less settled
• Digital content — generally not taxable
• Streaming — generally not taxable

For SaaS and digital-only businesses, Oklahoma is generally a non-taxable state.

Grocery exemption: Oklahoma exempts most grocery items from the state rate, which reduces effective collection for food sellers.
