10 Ohio Property Tax Calculators & Auditor Tools
Built specifically for Ohio's 35% assessment ratio, current DTE forms, and 2026 Homestead, Owner-Occupancy, CAUV, Conveyance Fee, and Board of Revision rules. Every number reflects verified Ohio Department of Taxation amounts.
Annual Tax Bill Estimator
OHIOApplies Ohio's 35% assessment ratio plus your county's effective millage tier — the actual math your auditor uses.
Homestead Reduction Calculator
DTE 105A2026 Ohio Homestead: $29,000 general or $58,000 enhanced (100% disabled vet, KIA spouse). OAGI under $41,000 required for non-veteran applicants.
Owner-Occupancy & Non-Business Credits
DTE 105CEvery Ohio owner-occupied home qualifies for the 2.5% Owner-Occupancy Credit plus the automatic 10% Non-Business Credit. Most owners don't realize these stack.
Conveyance Fee Calculator
ORC 322When you sell or transfer Ohio property, the auditor collects $1 state + up to $3 county per $1,000, plus $0.50 per parcel. Counties choose their rate.
CAUV Agricultural Savings
DTE 109Ohio's Current Agricultural Use Value cuts taxable value dramatically for farmland (10+ acres, or smaller with $2,500+ annual gross income).
Mill Rate Converter
Ohio tax rates appear three ways on auditor sites: mills, percent, or dollars per $1,000. Convert between them instantly.
Parcel Number Cleaner
Ohio's 88 counties each format parcels differently — Franklin uses 010-123456-00, Cuyahoga uses 001-23-456, Hamilton uses 100-0001-0001-00. Auto-detects.
35% Ratio Sanity Check
Ohio law sets taxable value at 35% of market value. If yours is significantly higher, you're a strong BOR appeal candidate.
BOR Appeal Savings
DTE 1A successful Board of Revision complaint typically cuts your value 10–20%. Filing is free and stays in effect until the next reappraisal.
BOR Deadline Countdown
MAR 31Ohio's statutory Board of Revision filing deadline is March 31 for the prior tax year. Miss it and you wait until next year — no extensions.
Verify with the official Ohio source
These calculators use the verified 2026 Ohio Department of Taxation amounts and statutory rules. For your exact bill, exemption status, and county-specific deadlines, always confirm with your county auditor and the Ohio Revised Code:
Estimates use Ohio's 35% statutory assessment ratio and effective tax rate tiers averaged across major Ohio counties. Your actual bill depends on local school levies, voted millage, inside vs. outside millage splits, House Bill 920 reduction factors (HB 920), and special assessments. The 2026 Homestead general amount ($29,000) and enhanced amount ($58,000) reflect HB 187 inflation indexing — your county auditor's office may show slightly different transitional figures.
