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 the parcel before using the information. Match the property address and parcel ID—not only the owner name. An Auditor property record is not a title opinion, and a GIS parcel line is not a legal boundary survey.

Quick answer: which Butler County search should you use?

Start with Owner Search when you know the owner, Address Search when you know the location, or Parcel ID Search when you have a bill, deed or prior record. Use Sales Search for comparable transactions, Advanced Search for multiple criteria and the GIS Viewer for map context.

1 Select one search method Owner, address or parcel ID.

2 Enter fewer details first Use the county’s required format.

3 Open the matching parcel Verify address and parcel number.

Correct county office or tool for common property tasks
What you need	Use this office or tool	What it provides	Important limit
Owner, address, parcel, value, building or sale	Auditor Property Search	Parcel records, appraisals, transfers, sales, values, taxes and map links.	The owner field is not a substitute for the recorded deed.
Tax bill, payment, penalty or delinquent plan	Treasurer	Tax collection, payment posting, escrow, autopay and delinquency assistance.	The Auditor does not collect property-tax payments.
Deed, mortgage, lien, release or easement	Recorder	Recorded documents, OCR searches, historical indexes and certified copies.	A public search does not guarantee clear title.
Parcel map or nearby-lot context	Auditor GIS Viewer	Map-based parcel identification, aerial context and geographic layers.	GIS boundaries are not surveyed legal boundaries.
Parcel split, plat or combination	Auditor, Engineer and Planning	Parcel creation, planning approvals, plat processing and tax-map review.	Approvals vary by city and township.

Homestead, owner occupancy or CAUV	Auditor Real Estate Division	Eligibility guidance, applications, renewals and program administration.	Each program has separate qualifications and deadlines.

Best workflow: Identify the parcel through the Auditor, copy the Parcel ID and use that same identifier when paying taxes, searching Recorder documents, opening GIS or filing a valuation complaint.

Troubleshooting and maintenance

No property result—or the system is unavailable?

Owner search returns nothing Try the surname only, one word from an LLC or trust, a former owner or an asterisk wildcard.

Address search fails Remove the suffix, city, ZIP code, unit number and punctuation. Search the street word alone.

Parcel ID returns nothing Use a shorter beginning portion with an asterisk, then confirm the active parcel.

The property recently sold Search the seller and check the Recorder’s current Cloud Search.

The parcel was split or combined Search the map location and contact the Auditor with old and new parcel information.

A TIF or RID number looks different TIF and RID parcel identifiers may contain 15 characters rather than the usual 14.

The portal shows maintenance Retry later, use the official GIS Viewer for map research and do not enter information on an unofficial site.

The result appears outdated Compare the “Data Current as of” date with the deed’s recording date.

2026 reappraisal explained

Understand the new 2026 property value

Butler County completed a state-mandated reappraisal for tax year 2026. The Ohio Department of Tax Equalization approved the tentative values on June 25, 2026, and the county reports a median countywide increase of 19%.

Value year 2026

New reappraisal value.

Tax payment year 2027

New value affects taxes payable next year.

Countywide median +19%

Individual parcels can differ substantially.

BOR deadline March 31, 2027

For a complaint against the 2026 value.

A 19% value increase does not mean a 19% tax increase. Tax rates, reduction factors, credits, inside millage, school funding rules, levies and state-law changes all affect the final bill.

Evaluate whether the value is reasonable

Recent purchase Compare the Auditor value with the price paid in a valid open-market transaction.

Recent refinance appraisal Compare the value with a credible appraisal prepared near the January 1, 2026 valuation date.

Neighborhood sales Compare similar arm’s-length sales using the county’s Neighborhood Sales Dashboard.

Property condition Document serious repair needs, damage, demolition or factual record errors.

Why neighbors can change by different percentages

Even similar-looking properties can differ in land size, grade, condition, living area, basement finish, garage space, improvements and recent market activity. The Board of Revision focuses on evidence of the subject property’s market value—not whether another parcel’s percentage increase was smaller.

Current Tax Distribution versus the new reappraisal

The Current Tax Distribution tab presently reflects tax year 2025, payable in 2026. Individual 2026 tax bills payable in 2027 will not be calculated until later. Use the distribution tab to understand current levies, but do not treat it as the final 2027 bill.

Sales and advanced research

Use Sales Search and Advanced Search correctly

Butler County’s Sales Search and Advanced Search let users build multi-criteria queries. At least one criterion must be selected and added to the Current Search Criteria box before the search will run.

Select a criterion Choose sale date, location, value, class, owner, district or another available field.

Enter the criterion value Add a date range, number, word or selection required by the chosen field.

Select Add The criterion is not active until it appears in the Current Search Criteria box.

Add another field only when useful Combine criteria such as sale period, property class and neighborhood.

Review every active criterion When editing a field, select Add again so the change takes effect.

Run and verify the result Compare the selected transactions with the subject parcel’s actual characteristics.

Map research and boundaries

Use the GIS Viewer without treating it as a survey

The Auditor GIS Viewer is useful for locating a parcel, examining neighboring lots and reviewing geographic context. The map can identify a parcel when the user selects its line or polygon.

Find the Parcel ID first Copy it from the Auditor property record whenever possible.

Open the official GIS Viewer Allow the ArcGIS application to finish loading before searching.

Search or navigate to the property Use Parcel ID, address or map movement based on the available controls.

Select the parcel polygon Confirm the Parcel ID, owner and address in the information panel.

Review nearby parcels and layers Use the map for location, development and neighborhood context.

Move to deeds, plats or survey records for exact work Do not measure a fence, structure, driveway or easement from the online parcel line.

Boundary warning: GIS parcel polygons are maintained for tax-map and public-research purposes. A GIS screenshot does not establish legal title, a monument location, an encroachment, a setback or an exact boundary.

Use the right record for the question

Map and boundary records compared
Record	Best use	Do not assume
Auditor GIS	Finding and comparing parcels visually.	The displayed line is an exact ground boundary.
Recorded deed	Reviewing the ownership instrument and legal description.	The written description marks itself on the ground without survey interpretation.
Recorded plat	Understanding subdivision lots, streets, easements and dimensions.	Every present physical feature matches the original plat.
Professional survey	Locating boundaries and monuments on the ground.	An old survey always reflects later transfers or changes.

Board of Revision action plan

Challenge a Butler County property value

2026 reappraisal complaint deadline: A complaint against the tax-year 2026 value can be filed from the first Monday in January through March 31, 2027.

The Board of Revision reviews property value—not the amount of tax owed. A complaint is generally limited to once during each three-year reappraisal cycle unless the property’s condition changes in a way that affects value.

Evidence the Board can evaluate

Recent arm’s-length open-market sale

Recent independent credible appraisal

Agent comparative-market analysis

Similar recent neighborhood sales

Significant property damage

Documented necessary repairs

Incorrect building or land facts

Photos and supporting records

Weak evidence: The Board’s 2026 FAQ says another property’s assessed value, tax amount or percentage increase is not evidence of the subject property’s market value.

File the complaint in six steps

Review the complete parcel record Verify the 2026 value, land, buildings, transfer history and factual characteristics.

Determine the value you can support State an evidence-based market value rather than requesting an arbitrary tax reduction.

Complete DTE Form 1 Use the current form released for the 2027 filing period.

Attach supporting documents Organize each appraisal, sale, photograph, estimate or factual correction.

Submit through SmartFile, email or mail Follow the county’s current instructions and retain proof of filing.

Prepare for the hearing A notice will be sent by email or certified mail after the hearing is scheduled.

After filing

A reduction request of $50,000 or more may permit another interested party, such as a Board of Education, to file a counter-complaint.
The county asks taxpayers to allow approximately three to four weeks after the hearing for the Notice of Result.
The 2026 FAQ says the Board has 90 days to issue its decision.
An appeal to the Ohio Board of Tax Appeals generally must be filed within 30 days of the decision being sent.
A complainant may also appeal to Butler County Common Pleas Court.

Ten practical answers

Butler County property search FAQs

How do I search Butler County Ohio property records by owner?

Open the official Butler County Auditor Owner Search and enter the name as LastName FirstName without a comma. Begin with the surname alone when the exact owner format is unknown. The search also supports an asterisk wildcard for partial names.

How should I enter an address in the Butler County property search?

Enter the street number and main street name but leave out the suffix such as Street, Road, Avenue or Drive. The address search supports an asterisk wildcard, and the street name can be searched without a house number.

Can I use a partial Butler County parcel number?

Yes. Butler County accepts all or part of a parcel number and supports an asterisk wildcard. Most real-estate parcel numbers contain 14 characters, while manufactured-home, RID and TIF identifiers can have different lengths.

What should I do when the Butler County property-search system is under maintenance?

Do not use an unofficial payment or property website. Retry the official portal later, use the Auditor GIS Viewer for map-based parcel research, or call the Auditor at 513-887-3154 with the owner, address and parcel details available.

What does the Butler County 2026 reappraisal mean?

The 2026 reappraisal establishes new market values for tax year 2026, payable in 2027. Butler County reports a countywide median value increase of 19 percent, but a value increase does not automatically create an equal percentage increase in taxes.

When are Butler County property taxes due in 2026?

First-half 2025 real-estate taxes were due February 26, 2026. Second-half 2025 real-estate taxes are due August 19, 2026. Manufactured-home tax dates are separate.

Where can I search Butler County deeds and mortgages?

Use the Butler County Recorder’s Real Estate Records Cloud Search. Documents from 1987 to the present are available online, and separate geographic, alphabetical, specialty and historical indexes help research older records.

Are Butler County GIS parcel lines legal boundaries?

No. The Auditor GIS Viewer is useful for locating parcels and examining nearby properties, but an online parcel line is not a legal boundary survey. Use recorded deeds, plats and professional surveying assistance for exact boundary decisions.

How do I challenge a Butler County 2026 property value?

File DTE Form 1 with the Butler County Board of Revision between the first Monday in January and March 31, 2027. Submit evidence focused on the subject property’s market value, such as a recent arm’s-length sale, credible appraisal, comparable-market analysis or evidence of serious damage.

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.
