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.

Beacon fields and practical next steps
Record field	What it means	What to do next
Parcel ID	The county identifier assigned to the tax parcel.	Use it for payment, deed, map, survey and appeal questions.
Owner name	The ownership name currently displayed in the assessment system.	Use the recorded deed when legal proof is required.
Market value	The Auditor’s estimate of fair market value.	Compare parcel facts, condition and valid recent sales.
Taxable value	Generally 35% of market value under Ohio assessment rules.	Use the applicable effective tax rate and credits.
Land value	Value assigned to the land portion.	Check acreage, class, homesite and CAUV status.
Improvement value	Value assigned to homes and other buildings.	Verify size, age, grade, condition and outbuildings.
Transfer history	Sales or ownership transfers associated with the parcel.	Open the actual deed through Recorder records.
Tax History	Tax liability and prior-year tax information.	Use the Treasurer for payment status and receipts.
Tax Distribution	How the parcel’s tax is distributed among taxing authorities.	Use it to understand—not dispute—the destination of the tax.
Proposed Levy	Estimated impact of eligible upcoming ballot levies.	Treat it as an estimate rather than a final future bill.

Valid-sale warning: A transfer price is not automatically market evidence. Family transfers, foreclosures, partial interests, estate transfers and special financing may not represent an arm’s-length sale.

Tax calculation explained

Why market value is not the final tax bill

$300,000 Example market value

35% Ohio assessment percentage

$105,000 Example taxable value

The taxable value is then multiplied by the parcel’s effective tax rates. Reduction factors, qualifying credits, Homestead, special assessments and TIF treatment can change the final amount.

Ten practical answers

Union County Ohio property search FAQs

What is the official Union County Ohio property search?

The Union County Auditor links to the official Beacon Property Search. It supports parcel, owner, address, sales, comparable-property, tax-history, tax-estimator and map research.

How do I search Union County property by owner name?

Begin with the owner’s last name or one distinctive word from a trust, estate or business name. Add the first name only if too many results appear. Try the previous owner when a transfer is recent.

How do I find a Union County parcel by address?

Start with the house number or the house number plus the main street name. Remove directions, road suffixes, punctuation and unit information if the complete address produces no result.

When are Union County Ohio property taxes due in 2026?

The first-half real-estate deadline was February 18, 2026. Union County’s current notice lists August 12, 2026 for second-half real-estate taxes and August 31, 2026 for manufactured-home taxes. Confirm the live account with the Treasurer.

Where can I see Union County tax history?

Open the property in Beacon and scroll to the Tax History section. Union County states that tax year 2025 taxes payable in 2026 are available there.

Are Union County GIS parcel lines legal boundaries?

No. GIS maps are useful for locating parcels, viewing aerial imagery and researching nearby land, but they do not replace a recorded deed, subdivision plat, survey record or professional boundary survey.

How do I find a Union County deed or mortgage?

Use the Union County Recorder’s official-record search. Online images and indexes are available from 1995 forward, with additional historical deed, mortgage and miscellaneous indexes available for earlier periods.

How do I challenge a Union County property value?

Find and select the parcel in Beacon, choose the Petition to Board of Revision option, and follow the current DTE 1 process. Complaints concern market value rather than tax rates and are generally filed by March 31.

How does Union County CAUV work?

Qualifying agricultural property of at least 10 acres, or smaller property producing at least $2,500 in qualifying annual agricultural income, may be valued according to agricultural use. A $25 initial fee and annual renewal apply.

Who handles Union County property-tax payments?

The Union County Treasurer handles balances, payments, receipts, penalties, escrow and delinquent-payment plans. The Auditor handles values, tax calculations, exemptions, parcel records and valuation complaints.

Information checked August 6, 2026: Property-search tools, Beacon functions, 2026 tax deadlines, office contacts, payment resources, GIS, survey records, Recorder coverage and fees, Board of Revision guidance, Homestead, CAUV, manufactured homes, conveyance fees and delinquent-payment options were checked against official Union County sources.

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.
