How Wyoming's rate is built
Every combined rate in the tables above starts from the same 4.00% statewide base component, per this data set. Wyoming's data doesn't record any special-district add-ons beyond the county/city layer itself — every jurisdiction's rate is just its own local rate on top of the state base.

Where this data comes from
Rates come from the official Streamlined Sales and Use Tax Agreement (SSUTA) "Rate and Boundary" files that Wyoming, as an SST member state, is required to publish free to the public under SSUTA §§305 and 307 (streamlinedsalestax.org). Jurisdiction names (city, county, and county-subdivision) are matched against U.S. Census Bureau Gazetteer name files by FIPS code — this page invents no jurisdiction names of its own. The data set behind this page was last pulled 2026-10-02; SST posts updated files ahead of each calendar quarter and issues mid-quarter corrections when a jurisdiction changes its rate.

Frequently asked questions
What's the sales tax rate in Laramie County?
Laramie County has a combined sales tax rate of 5.00%, per the official Streamlined Sales Tax data as of 2026-10-02. It's the largest jurisdiction in this data set by ZIP-code coverage, used here as the best available size proxy since the SST files don't publish population figures.
Why do sales tax rates vary within the same ZIP code in Wyoming?
A combined rate is a stack, not a single number: the state's own component (4.00% per this data set) plus whatever the county, city, and any special district (transit, tourism, public safety) each add on top. ZIP codes were drawn by the Postal Service to route mail, not to follow city or county lines, so a single ZIP can straddle more than one of those taxing boundaries — which is why the ZIP-code calculator above sometimes shows a range instead of one figure.
How often is this Wyoming sales tax data updated?
The underlying data set was last pulled 2026-10-02. This site checks for a refresh monthly, but the Streamlined Sales Tax Governing Board itself only republishes member-state rate and boundary files on a quarterly cadence (ahead of each calendar quarter, with mid-quarter corrections when a jurisdiction changes its rate) — so most months there is nothing new to pull.
Are groceries taxed differently in Wyoming?
Statewide, Wyoming exempts groceries from the general sales tax (per Wyoming's own base-rate table) — none of the jurisdictions in this ZIP-level data set publish a separate reduced grocery rate distinct from that exemption.
Which Wyoming jurisdiction has the highest combined sales tax rate?
Teton County (Teton County), at 7.00% combined, per the official Streamlined Sales Tax data as of 2026-10-02. At the other end, Park County sits at 4.00% — see the highest & lowest table below for the full top-10 spread each way.
