Find a Parcel, Tax Record, Map or Deed
Search Union County property records by owner name, street address or parcel number, then use the detailed parcel report to check ownership, market value, assessed value, building facts, transfers, tax history and the property’s taxing district.
This guide explains what to type, what each result means, why a record may be missing, which county office handles the next step, and how to move from a parcel search to taxes, GIS maps, deeds, exemptions or a valuation complaint without wasting time.
Quick answer: where do you search?
Use the official Union County Beacon Property Search for owner, address, parcel, value, building, sale and tax-history information. Start with less information, select the correct Parcel ID from the results, open the detailed Report, and scroll to Tax History for tax year 2025 payable in 2026.

8:30 a.m.–4:00 p.m., Monday–Friday.
Closed 8:30–10:00 a.m. on the third Tuesday each month for a department meeting.
After following the four steps above, open the county-authorized Beacon search. The county’s help page explains that the results list leads to the Parcel ID, detailed Report, map layers, sales tools, comparable search, estimators and exports.

Which Union County office handles your property question?
The Auditor, Treasurer, Recorder and Engineer maintain different parts of the property workflow. Start with the Auditor to identify the parcel, then move to the office that controls the action you need.

Search by owner name, address or parcel number
The most common search mistake is entering too much information. Union County’s own GIS and property-search guidance recommends beginning with fewer fields and narrowing the result only when necessary.
- Enter the last name only.
- Run the search before adding the first name.
- If too many matches appear, add the first initial or first name.
- Remove punctuation, middle initials and suffixes if nothing appears.
- Try a trust, company, estate or former-owner name when relevant.
- Enter the house number.
- Add the main street word.
- Leave out Road, Street, Avenue and directional letters initially.
- Remove unit numbers and punctuation if the search fails.
- Verify the taxing district because mailing-city wording can differ.
- Copy the number from a tax bill, deed or prior property card.
- Enter the complete identifier first.
- If no result appears, remove spaces or separators.
- Check that zero was not entered as the letter O.
- Confirm the address before using the record.

Prepare this information before calling the Auditor
Understand every important parcel-report field
The detailed report is useful only when you know what each field can—and cannot—prove. Use the next-action column to avoid taking a property-search field out of context.
Field |
What it means |
Practical next action |
|---|---|---|
Parcel ID |
The county identifier assigned to the parcel. |
Use it for tax, map, deed, form and office questions. |
Owner |
The ownership name currently displayed by the Auditor. |
Use the recorded deed when legal ownership proof is needed. |
Mailing address |
The address used for tax or ownership correspondence. |
Do not confuse it with the property’s physical location. |
Taxing district |
The combination of local taxing authorities applying to the parcel. |
Use the parcel-specific district when checking rates and levies. |
Market value |
The Auditor’s estimate of open-market property value. |
Review parcel facts and recent valid sales before disputing it. |
Assessed value |
Generally 35% of market value under Ohio’s property-tax system. |
Do not multiply it by a random countywide rate; districts differ. |
Land value |
The portion of value assigned to the land. |
Check acreage, use, frontage and CAUV status where relevant. |
Building value |
The value assigned to structures and improvements. |
Check square footage, age, condition, grade and outbuildings. |
Property class |
The recorded property-use classification. |
Contact the Auditor if the actual use is materially different. |
Transfer date and price |
The recorded sale or transfer information connected with the parcel. |
Check the transaction type before treating it as a market sale. |
Deed reference |
A clue leading to the recorded ownership instrument. |
Use it in the Recorder’s official-record search. |
Tax History |
Tax liability organized by tax year and payable year. |
For 2026 collection, review tax year 2025 payable in 2026. |
Check building facts before questioning the value
- Living area and floor area
- Year built and effective age
- Building grade and condition
- Basement and finished area
- Garage, barn and outbuilding details
- Land acreage and property use
- Current photographs
- Measurements or floor plans
- Permit or demolition records
- Contractor estimates
- Survey or recorded deed
- Damage reports
Why a value increase and tax increase may differ
The Auditor establishes market value. The final tax calculation also depends on assessed value, the taxing district’s effective rates, reduction factors, credits, voted levies and special assessments. A percentage increase in market value does not automatically produce the same percentage increase in the tax bill.
After finding the parcel, use Beacon’s “Where your taxes go” or property-report information to identify the parcel’s effective rate and levy details.
Check tax dates, fees and payment problems
Union County’s official property-search notice says 2026 property taxes are calculated and available. Search the parcel, open Tax History and review tax year 2025 payable in 2026.

Monthly and delinquent payment options
The Treasurer offers an escrow program for monthly prepayments of current taxes. Written delinquent-payment contracts may allow installment payments while the taxpayer keeps current taxes paid. The county FAQ says penalty and interest may be held in escrow during a compliant delinquent contract and added back if the taxpayer defaults.
After reviewing the steps and fees above, use the Treasurer’s official payment page. Use the Payment Information page for live dates and the Treasurer FAQ for processor fees, mailing rules and common billing problems.
Use GIS, aerial images, surveys and plats
Union County GIS can show parcel boundaries, buildings, aerial photography, land characteristics, soil types, hydrography and political boundaries. Use it for location and research—not as legal boundary proof.

Where to find surveys and subdivision plats
The Union County Engineer creates and maintains tax maps, reviews new and existing legal descriptions, maintains survey records and reviews subdivision plats. The Recorder keeps original recorded land documents. The county warns that not every subdivision plat is available online.
7:30 a.m.–4:30 p.m., Monday–Friday.
After identifying the parcel and understanding the limits above, open the official GIS page for the interactive map or the Engineer’s Property & Survey page for tax maps, survey records, atlases and subdivision plats.
Find recent sales and comparable properties
Beacon includes Sales Search, monthly sales and transfer lists, Comp Search and Excel-compatible exports. A useful comparison needs more than a nearby address or a similar sale price.
- Same or similar taxing district
- Nearby township, city or village
- Similar school-district influence
- Comparable road and neighborhood setting
- Property class and use
- Building style and living area
- Age, grade and condition
- Lot size and outbuildings
- Recent sale date
- Arm’s-length exposure to the market
- No special financing
- No foreclosure or bankruptcy distortion
Exclude misleading transfers
Use the official Beacon Help page after reviewing the comparison rules above. Its Sales menu explains advanced searches, monthly transfers, Comp Search and export controls.
Find deeds, mortgages, liens and easements
Use the Recorder when you need the actual recorded instrument. The Auditor property card can help identify an owner, transfer date and deed reference, but it does not replace the recorded document.

Challenge an incorrect property value
File a Board of Revision complaint only when the dispute concerns the parcel’s market value or assessment—not simply because the tax bill is high. The official Board page says the Board can raise, lower or make no change to value.

Strong evidence for a recent purchase
Union County recommends documents such as the closing statement, purchase contract, escrow statement, deed and relevant addenda. The Board page describes a useful recent sale as a valid transaction without special financing, foreclosure or bankruptcy and generally within 24 months of the January 1 tax-lien date.
After the decision
- Decisions are held for 30 days while an appeal may be filed.
- The county says record adjustment and refund or credit processing can take approximately 60 additional days.
- An appeal to the Ohio Board of Tax Appeals or Court of Common Pleas generally must be filed within 30 days of the decision letter.
- If the requested market-value change exceeds $50,000, or $17,500 assessed value, the school district Board of Education must be notified.
- Property owned by a business entity or trust may create representation issues; the county strongly recommends attorney help in those cases.
After reviewing the risks and evidence requirements above, use the official Board of Revision page and Auditor FAQ for the current DTE forms, procedures and hearing guidance.

What to bring or include in your message
Could the property be in a neighboring county?
A mailing address, ZIP code or nearby road can sometimes make a parcel appear to be in Union County when it is actually recorded in a neighboring county. Confirm the county before searching repeatedly.

Union County property search FAQs
How do I search Union County property records by owner name?
Open the official Union County Beacon property search and begin with the owner’s last name only. Add the first name or initial only when the results are too broad, then verify the result with the property address and parcel ID.
Can I search a Union County parcel using only an address?
Yes. Begin with the house number and main street name. If no result appears, remove the directional letter, unit number, punctuation and street suffix such as Road, Street or Avenue.
Why is a recently purchased property still listed under the former owner?
The recorded deed and public Auditor display may not update at exactly the same time. Search the former owner, check the Union County Recorder’s official records and contact the Auditor if the ownership display remains unchanged.
What is the difference between market value and assessed value in Ohio?
Market value is the county’s estimate of open-market property value. Assessed value is generally 35 percent of market value in Ohio and is used with the parcel’s applicable tax rate, reduction factors, credits and special assessments to calculate the bill.
Why do 2025 values appear on a 2026 Union County tax bill?
Ohio real-estate taxes are collected in arrears. Union County instructs users to review tax year 2025 in Beacon’s Tax History section for the property-tax liability payable during 2026.
Are Union County GIS parcel lines legally exact?
No. GIS boundaries help users locate and compare parcels but are not a legal boundary survey. Use recorded deeds, plats and surveys and obtain professional help before making a fence, building, driveway, easement or boundary decision.
Where can I find a Union County deed, mortgage or lien?
Use the Union County Recorder’s official-record search. The Recorder publishes online images and indexes from 1995 to the present and separate historical indexes for many earlier deeds, mortgages and miscellaneous records.
How do I challenge an incorrect Union County property value?
Review the parcel facts first, collect value evidence and file the current DTE 1 Board of Revision complaint. The notarized complaint and supporting documents must normally be received after January 1 and on or before March 31 for the applicable tax year.
What is the difference between owner occupancy, Homestead and CAUV?
Owner occupancy is an additional reduction for a qualifying primary residence. Homestead provides relief for eligible senior, disabled, veteran or surviving-spouse homeowners. CAUV values qualifying agricultural land according to agricultural use rather than ordinary development-market value.
Who should I call about a Union County property-tax payment problem?
Call the Union County Treasurer at 937-645-3035 for bills, payment posting, escrow, delinquency and payment plans. Call the Auditor at 937-645-3003 for property values, parcel facts, credits, exemptions, CAUV and Board of Revision questions.

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.
