What is the Ohio property tax assessment ratio?

Ohio law sets taxable value at 35% of market (true) value statewide, under Ohio Revised Code §5713.03. Your county auditor must use this ratio when calculating your tax bill.

How much is the Ohio Homestead Reduction in 2026?

For tax year 2026, the general Homestead Reduction shields $29,000 of market value for qualifying owners age 65+, totally disabled, or surviving spouses age 59+ with Ohio Adjusted Gross Income under $41,000. The enhanced amount for 100% disabled veterans and surviving spouses of public-safety officers killed in the line of duty is $58,000 with no income limit. File DTE Form 105A with your county auditor.

When is the Ohio Board of Revision deadline?

Ohio's statutory Board of Revision (BOR) complaint deadline is March 31 for the prior tax year, per ORC §5715.19. Complaints are filed using DTE Form 1 with your county auditor at no cost. Late filings are rejected except in very narrow clerical-error circumstances.

How much is the Ohio real property conveyance fee?

Ohio's conveyance fee has two parts: a mandatory $1.00 per $1,000 state fee (ORC §319.54(F)(3)) and a permissive county levy of up to $3.00 per $1,000 (ORC §322.02). Most Ohio counties charge the full $4.00 per $1,000. A separate $0.50 transfer fee applies per parcel. Filed using DTE Form 100 at the auditor's office at closing.

Who qualifies for Ohio's CAUV agricultural tax break?

Ohio's Current Agricultural Use Value (CAUV) program lets actively farmed land be taxed on its agricultural value rather than its market value. Eligibility requires 10+ acres devoted exclusively to commercial agriculture, or smaller parcels with $2,500+ in gross annual income from agriculture. Apply using DTE Form 109 and renew annually with DTE 109A. Removing land from CAUV triggers recoupment of three years of saved taxes under ORC §5713.34.

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:

Ohio Dept. of Taxation — Real Property DTE Forms (105A, 105C, 1, 109) ORC 5715 — Board of Revision ORC 5713 — Taxable Real Property ORC 322.02 — Conveyance Fee ORC 319.54(F)(3) — State Fee ORC 5713.30 — CAUV tax.ohio.gov — Main Portal

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.
