How ZIP-Code Sales Tax Lookup Works in Ohio

Ohio doesn't tax by city or ZIP code. It taxes by county (plus any regional transit levy), and which county applies depends on who is selling: an Ohio vendor sources an intrastate sale to its own location under R.C. 5739.033(B)(1), while an out-of-state or marketplace seller sources to the buyer. Either way the answer is a county rate. So the honest way to "look up tax by ZIP" is to map the ZIP to the county it sits in, then apply that county's combined rate. That's exactly what this calculator does, across every Ohio ZIP code.

The border-ZIP caveat

A ZIP code is a USPS mail-delivery route, not a tax boundary, and a handful of ZIPs straddle two counties. We resolve each ZIP to its primary county, which is correct for the overwhelming majority of addresses. If you're right on a county line, confirm the exact jurisdiction with Ohio's official The Finder by full address, or use our county rate pages directly.

Looking for the general tool?

If you already know your county, the main Ohio sales tax calculator covers all 88 counties, handles exempt item types like groceries and prescriptions, and now takes a ZIP code as well. This page exists for the ZIP-first lookup.

Why not just trust any ZIP tool?

Many generic tools return a single blended rate per ZIP and quietly get border addresses wrong. Because Ohio's rate is a clean state 5.75% plus a fixed county levy, mapping ZIP → county → rate is both simpler and more transparent. You always see which county we matched.

Sales Tax = Amount × Combined Rate
Combined Rate = State 5.75% + County Rate (for the ZIP's county)

Example: A $100 purchase in ZIP 43215 (Columbus, Franklin County, 8.00%) owes $100 × 0.08 = $8.00 in tax. The state portion is $5.75 and the Franklin County portion is $2.25, for a $108.00 total.

ZIP 45011 — Hamilton, Butler County (6.50% — lowest)$100 × 0.0650$6.50 tax → $106.50 total
ZIP 45402 — Dayton, Montgomery County (7.50%)$200 × 0.0750$15.00 tax → $215.00 total

Quick facts

  • Ohio sets sales tax by county, not by city or ZIP — so a ZIP lookup really means "which county is this ZIP in?"
  • This calculator covers every Ohio ZIP code and maps each to its primary county's 2026 combined rate.
  • Combined rates range from 6.50% (Butler, Lorain, Stark, Wayne) to 8.00% (Cuyahoga, Franklin).
  • ZIP codes can cross county lines; on a border, verify by full address with Ohio's The Finder.
  • The state base is 5.75% everywhere; only the county (and any transit levy) changes the total.

Frequently asked questions

Enter the 5-digit Ohio ZIP code and your purchase amount above. We map the ZIP to its primary county and apply that county's 2026 combined rate (state 5.75% plus the county levy), then show the tax and total. Because Ohio taxes by county, the ZIP's county is what actually determines the rate.

Neither, strictly — Ohio taxes by county, and for an Ohio seller the sale is sourced to the seller's own location under R.C. 5739.033(B)(1), not the buyer's. A ZIP code is just a proxy for the county. For the vast majority of ZIPs there is exactly one county, so the ZIP gives the right rate. For a ZIP that straddles a county line, confirm the exact county by full address using Ohio's The Finder.

Two reasons. First, ZIP boundaries were drawn for mail delivery, not taxes, so a small number of Ohio ZIPs span two counties with different combined rates; this tool resolves each ZIP to its primary county, which is correct for most addresses. Second, and less well known, five counties are split by a regional transit district that raises the rate inside its boundary: Delaware (7.00% countywide, 8.00% inside COTA), Fairfield (6.75% / 7.75% COTA), Licking (7.25% / 8.25% COTA), Union (7.00% / 8.00% COTA) and Wood (6.75% countywide, 7.25% inside the TARTA district covering Rossford). In those five, the county is right and the rate can still be higher for a specific address. Check the full street address with The Finder.

ZIP 43215 is in Franklin County, whose 2026 combined rate is 8.00% (5.75% state + 2.25% county and COTA transit levy). So $100 there is $8.00 in tax, for a $108.00 total.

Yes. The tool maps more than 1,400 Ohio ZIP codes (the 43000–45999 range) across all 88 counties, so you can look up the combined rate for any location in the state.

If you enter a ZIP outside Ohio or a typo, the calculator will let you know. Double-check the 5 digits, or if you know your county, use our county rate pages directly for the exact figure.
