Oklahoma Sales Tax Guide (2026)
4.5% at state level and local rates high enough that the surviving local tax on groceries is often larger than the state tax that was removed.[1]
Sales Tax at a Glance
The state stopped taxing groceries; every locality kept doing so
House Bill 1955 set the state rate on food and food ingredients to zero from 29 August 2024, and expressly preserved city, town and county taxes on the same items regardless of ordinance or contract.[2]

Estimate only. The Tax Commission republishes its city and county rate chart each quarter, so confirm the figure before invoicing.[3] Talk to CrownGlobe about grocery rate configuration.
Oklahoma Sales Tax Rates, Nexus & the two rate tracks
Oklahoma state rates
| General retail sales | 4.5% |
| Food & food ingredients | 0% |
| Local tax on general goods | Applies in full |
| Local tax on food | Applies in full |
| Prepared food | 4.5% plus local |
Because the grocery relief is a zero state rate rather than an exclusion, the sale is still reported and still sourced to the correct city and county.[2]
Who must register
Either trigger applies: economic nexus at $100,000 or more of Oklahoma sales in the previous twelve-month period, with no transaction-count test, or any physical presence. The threshold rose from $10,000 on 1 November 2019, when the notice-and-report alternative also ended.[4]
Oklahoma County levies no county sales tax, which is why Oklahoma City’s combined rate is lower than Norman’s despite identical city rates. Never assume the largest city carries the highest rate.[3]

Sales Tax FAQs
4.5% at state level. City and county taxes are unusually high, so combined rates commonly run between 8% and 10% and can reach roughly 11.5% in some jurisdictions.
The state rate on food and food ingredients has been 0% since 29 August 2024 under House Bill 1955. City and county taxes were expressly preserved and still apply in full, so a grocery sale in Oklahoma City still carries 4.125%.
Bottled water, candy and soft drinks sold in a bottle or can are inside the zero-rated food class. Prepared food, alcohol, beer, dietary supplements, tobacco, fountain drinks, rotisserie chicken, deli items made by the seller, pet food and toiletries are outside it.
Yes, again. A moratorium barred localities from applying newly voter-approved increases to food until 30 June 2025. That window has closed, so grocery-reaching local increases can be put to voters once more.
$100,000 or more of Oklahoma sales measured over the previous twelve-month period, with no transaction-count test. The threshold rose from $10,000 on 1 November 2019, when the notice-and-report alternative also ended.
It runs on a three-year cycle. The permit is issued on a six-month probationary basis and then renews automatically for a further thirty months.
