Methodology
How the combined rate is built
A sales tax rate is a sum. The state sets one rate for every sale in the state; the county, the city and any special district (transit authority, hospital district, improvement district) the address sits in each add their own. The combined rate is those components added together, and the page lists every one with the authority that levies it and the date it took effect, so the total can be checked line by line.
Combined rate = state rate + county rate + city rate + district rates Tax = purchase amount × combined rate ÷ 100
Source and effective date
Every rate on this page comes from the Oklahoma Tax Commission, Rates and Codes for Sales, Use, and Lodging Tax (CSV), the file dated October 1, 2026 with rates effective October 1, 2026, read on October 8, 2026. Each local component carries the effective date the file states for it; the state component is dated by the file's own effective date. Sales tax rates are not tax-year figures: they change on the first day of a quarter, most often January, April, July and October 1. The snapshot behind these pages is rebuilt from the DOR file on the fifth of those months.
- Every local rate carries the date it took effect as the OTC file states it. The OTC file is updated as rates change; its latest effective date is used as the file date.
- Tribal nation codes in the file (CPN - MCLOUD, CPN - SHAWNEE, CPN - TECUMSEH) are not listed; they carry their own compact rate.
- A city that lies in more than one county is listed by OTC under one county code; the county portion for an address in another county differs.
Limitations
- General merchandise only. Groceries, prepared food, lodging, motor vehicles, fuel, alcohol and services are taxed at different rates or not at all, and that differs by state and within Alma, OK.
- A ZIP code is not a jurisdiction. ZIP codes cross county, city and district lines, so a receipt's ZIP does not set the rate; the taxing jurisdictions the address sits in do. That is why there are no ZIP pages here.
- Where the rate is measured. Oklahoma is a destination-based state: the rate at the address the goods are delivered to applies.
- Special districts that cover part of a jurisdiction (an address-range improvement district, a transit area that stops at a road) are listed under "other rate areas" where the DOR lists them and left out where it lists them only by address.
- Caps and thresholds (a surtax that applies only to the first $5,000 of an item, a maximum tax per sale) are not modeled; the split assumes the full rate on the full amount.
Last reviewed: October 2026. The state table was checked against each revenue department's page on October 8, 2026; the local snapshots are refreshed from the DOR files every quarter and checked by scripts/check-sales-tax.mjs before each deploy.
