Sales Tax Rate by ZIP Code

Combined Rate
10.550%ZIP-level rates cover the 24 Streamlined Sales Tax member states. Outside those states we fall back to the statewide base rate — never an invented local figure.
Edit inputs ↑How ZIP-code sales tax lookup actually works
A combined sales tax rate is never a single number set by one government. It's a stack: a state rate, layered with whatever a county, city, and special district (transit authority, stadium district, tourism improvement district) each choose to add on top. ZIP codes were built by the Postal Service to route mail efficiently, not to follow city or county lines — so a single ZIP frequently straddles two or more of those taxing boundaries.
That's the honest limitation behind every ZIP-based sales-tax tool, including this one: most of the time a ZIP maps cleanly to one rate, but where it doesn't, a tool that reports only a single number is quietly wrong for some of the addresses inside that ZIP. This calculator surfaces the split instead of hiding it — when the official data shows more than one rate inside a ZIP, both ends of the range are shown alongside the headline figure.
Where the data comes from
The Streamlined Sales and Use Tax Agreement (SSUTA) requires its 24 member states to publish standardized, machine-readable rate and boundary files free to the public — the "Rate and Boundary" files under SSUTA §§305 and 307. Those files are the source for every ZIP-level figure on this page; nothing here is scraped, estimated, or interpolated. States refresh their files ahead of each calendar quarter and post corrections mid-quarter when a local jurisdiction changes its rate. The dataset behind this calculator was last pulled 2026-08-04.

For everything outside those 24 states, SST doesn't publish an equivalent free ZIP-level file, so the calculator falls back to the state's statewide base rate and labels it explicitly as a base rate only. It never invents a local add-on to fill the gap. For the two biggest non-SST states we publish full city-and-county rate tables from each state's own official source instead — see California sales tax rates by city (CDTFA) and Texas sales tax rates by city (Texas Comptroller). For state-level reference pages, see California, Florida, and Texas.
Worked examples
Three real ZIP codes, computed live from the official dataset — a plain single-rate hit, a second plain hit, and a ZIP that genuinely spans more than one rate.
| ZIP | Area | Combined Rate | Range |
|---|---|---|---|
| 98101 | Seattle, WA | 10.550% | — |
| 43215 | Columbus, OH | 8.000% | — |
| 84101 | Salt Lake City, UT | 7.450% | 7.450%–8.450% |
84101 is the range case: the headline 7.450% is the lowest combination present in the ZIP, while some addresses inside it are taxed up to 8.450%. It also carries a separate groceries/drugs rate of 3.000%, lower than the general rate.
Frequently asked questions
Is the rate shown the exact rate for my address?
It's the exact rate for most ZIP codes — but not all. A single ZIP code can span more than one taxing jurisdiction (a city line, a special transit or stadium district, a county boundary), so two addresses that share a ZIP can legally owe different combined rates. When SST's ZIP+4 layer shows more than one rate inside a ZIP, this tool shows the full range as well as the single headline figure, so you know when to double-check with a specific street address rather than the ZIP alone.
Why does the headline rate show a range for some ZIP codes?
Because the ZIP genuinely contains more than one tax rate. Per the Streamlined Sales and Use Tax Agreement (SSUTA), the standard 5-digit "Z-record" rate published for a ZIP is defined as the LOWEST combined rate of any jurisdiction inside it — that's the headline figure this calculator leads with. Where SST's more granular ZIP+4 boundary layer shows a different rate for part of the ZIP, we surface that as a min–max range underneath, e.g. Salt Lake City's 84101 spans 7.450%–8.450%. Only a full street address pins down which end of the range applies.
Which states does this cover at the ZIP level?
The 24 states that belong to the Streamlined Sales Tax Governing Board and publish official ZIP-level rate and boundary files: Arkansas, Georgia, Indiana, Iowa, Kansas, Kentucky, Michigan, Minnesota, Nebraska, Nevada, New Jersey, North Carolina, North Dakota, Ohio, Oklahoma, Rhode Island, South Dakota, Tennessee, Utah, Vermont, Washington, West Virginia, Wisconsin, Wyoming. For the other 21 sales-tax states — including California, Florida, Texas, and New York — SST doesn't publish an equivalent standardized free file, so this tool falls back to the state's statewide base rate and says so explicitly rather than guessing at a local add-on.
How current is the data?
The dataset was last refreshed 2026-08-04, sourced directly from the official SST rate and boundary files published at streamlinedsalestax.org. SST posts updated files ahead of each calendar quarter and issues mid-quarter corrections as jurisdictions change their rates; this site re-fetches on the same cadence, so the figures here should track the SST publication schedule closely rather than a fixed annual snapshot.
Does this include grocery and drug rates?
Where SST publishes a food/drug rate that differs from the general combined rate for a ZIP, this calculator shows it as a separate line — for example 84101 (Salt Lake City) has a general rate of 7.450% but a groceries/drugs rate of 3.000%. When no separate figure is shown for a ZIP, SST's data doesn't record a food/drug carve-out different from the general rate there.
