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.

Match the parcel—not only the owner name. Confirm the physical address and parcel number before paying taxes, ordering records, filing a complaint or relying on a map. Similar owner names and multiple parcels can lead to the wrong property.

Quick answer: start with one clean search

Use the official Butler County Auditor property system. Search by owner, address or parcel number, open the matching parcel, verify two independent facts, and save the parcel ID before moving to tax payment, GIS, Recorder documents, Homestead, CAUV or Board of Revision.

Office-routing guide

Which official office handles your question?

The Auditor, Treasurer and Recorder work with the same property but control different records. Using the wrong office is one of the main reasons property tasks take longer than necessary.

Correct Butler County office or tool for each task
What you need	Use	What it provides	Important limit
Owner, address, parcel number or property value	Auditor property search	Parcel record, land, buildings, values, transfers, tax district and map links.	The owner display is not a title opinion.
Current tax bill, balance or payment	Treasurer	Tax bills, payment posting, online payment, AutoPay, escrow and delinquency help.	The Auditor does not collect the payment.
Deed, mortgage, lien, easement or release	Recorder	Recorded indexes, OCR document search, images and copies.	A database search is not a complete title examination.
Visual parcel location or nearby properties	Auditor GIS / map search	Parcel context, roads, nearby parcels, buffers and map exports.	GIS lines are not surveyed boundaries.
Recent sales or comparable properties	Sales Search / Advanced Search	Sale-date, price, location and property-characteristic filtering.	Not every transfer is a valid market sale.
Challenge appraised market value	Board of Revision	DTE Form 1 complaint and evidence-review process.	It does not remove tax rates or penalties.
Homestead, owner occupancy or CAUV	Auditor	Eligibility guidance, applications and annual agricultural renewal.	Each programme has separate requirements.
Deed transfer or conveyance fee	Auditor conveyance desk, then Recorder	Transfer review, DTE forms, conveyance fee and official recording.	The conveyance desk closes before the general Auditor office.

Most efficient sequence: Find the parcel, copy its parcel number, save the detailed property report and use that number in every subsequent tax, map, deed, form or office inquiry.

Exact property-search workflow

Search by owner, address or parcel number

Start broadly and narrow only when the result list is too large. One incorrectly entered name, suffix or parcel character can eliminate the correct result.

Owner-name search

Enter the last name first.
Add the first name after a broad search.
Do not use a comma.
Try one distinctive trust, LLC or estate word.
Use an asterisk when spelling is uncertain.

Examples: SMITH JOHN · SMITH · B*OWN

Address search

Enter the street number when known.
Enter the main street name.
Do not enter Street, Road, Avenue or Drive.
Search the street name alone if the number fails.
Use * before a partial street word if needed.

Example: 130 HIGH, not 130 HIGH STREET

Parcel-number search

Copy the number from a tax bill, deed or prior record.
Enter the complete identifier first.
Use a partial number when necessary.
Add * to return all records beginning with a sequence.
Confirm the location before relying on the result.

Most real-property numbers are 14 characters

Butler County parcel-number differences

Review every plausible result One owner can hold several homes, lots, commercial parcels or agricultural tracts.

Open the detailed property report Do not rely only on the short result row.

Confirm two independent facts Match the parcel number and location, or the location and building or acreage details.

Check the data-current date A recent deed or parcel change may be newer than the displayed processing date.

Save the parcel number Use it for the Treasurer, Recorder, GIS, tax calculator and Board of Revision.

Use Advanced Search only for research

Advanced Search is useful for appraisers, buyers, investors and researchers who need several criteria, such as transfer date, sale price, tax district, land class or building characteristics.

Select one criterion Choose the first field from the Criteria menu.

Enter the value Add the date, number, name or property characteristic requested.

Click Add The criterion must appear in the Current Search Criteria box.

Add more criteria carefully Every extra condition can remove otherwise relevant records.

Verify edits After changing a criterion, click Add again so the revision becomes effective.

Run and export only the necessary result Save the criteria used so the research can be repeated.

Outdated browser instruction: The official Advanced Search help still references Internet Explorer for its Save/Load function. Internet Explorer is retired. Build the search fresh in a current browser if saved criteria do not work.

After learning the search rules above, use the official owner, address, parcel, advanced or sales page matching your task.

Failed-search recovery

No Butler County property result found?

Owner search returns nothing Use LastName FirstName without a comma, then try the surname only, one business word or a wildcard.

Address search fails Remove Street, Road, Avenue, Drive, direction letters, unit numbers and punctuation.

Parcel number fails Enter only part of the identifier and check whether a zero was entered as the letter O.

Recent buyer is missing Search the seller or former owner and check the Recorder for the new deed.

New lot or house is missing Search the parent parcel, developer, builder, road or original owner.

Parcel was split or combined Search each old parcel number and ask whether a new identifier was created.

Manufactured home is missing Use the shorter manufactured-home identifier and verify the owner, park or location.

Understand every important property-record field

Butler County property record fields explained
Field	What it means	Practical next action
Parcel ID	The county identifier assigned to the property record.	Use it for tax, map, deed, calculator and office questions.
Owner	The ownership name currently displayed by the Auditor.	Use the recorded deed when legal ownership proof is required.
Property address	The situs or physical location associated with the parcel.	Compare it with GIS and the legal description.
Mailing address	The address used for tax and ownership correspondence.	Do not confuse it with the physical property location.
Appraised value	The Auditor’s estimate of fair market value.	Compare parcel facts, condition and valid market sales.
Assessed value	Generally 35% of appraised value under Ohio’s property-tax system.	Use the correct effective tax rate and district.
Land value	Value assigned to land rather than buildings.	Check acreage, land class, homesite and CAUV status.
Building value	Value assigned to structures and improvements.	Verify size, year, grade, condition, garage and outbuildings.
Transfer date and price	The sale or ownership-transfer information associated with the parcel.	Check the transaction type and Recorder document.
Tax district	The combination of local taxing authorities applying to the parcel.	Use the same district in the tax calculator.
Special assessments	Separate charges connected with a project or service.	Review current, delinquent, pending and future assessment columns.
Legal description	An abbreviated description used to identify the parcel.	Use the recorded deed for the complete legal description.

Special assessments need a separate check

A parcel can show special-assessment project numbers, project names and delinquent, current or future amounts. These charges can make the final bill differ from a simple value-times-rate estimate.

Buyer and homeowner tip: Open the special-assessment section before closing, refinancing or disputing the bill. A pending or future charge may not be obvious from the headline property value.

Value and tax calculation

Why appraised value, assessed value and the bill differ

Appraised value

The Auditor’s estimate of fair market value for the land and improvements.

Assessed value

Generally 35% of appraised value for Ohio property-tax purposes.

Final tax bill

Depends on effective rates, district, reduction factors, credits and special assessments.

Check the record before challenging value

Acreage and land class

Living area and building footprint

Year built and effective age

Grade and condition

Basement and finished area

Garage, barn and outbuildings

Recent additions or demolition

CAUV or exemption status

Possible reasons the tax bill changed

Appraised value changed A reappraisal, update, new construction, demolition or correction may affect value.

Effective rate changed Levy results and reduction factors can alter the rate applied to the parcel.

Credit changed Homestead or owner-occupancy status may have begun, ended or transferred incorrectly.

Special assessment changed A project charge may appear separately from ordinary property tax.

Delinquency or penalty appeared Payment timing and prior unpaid balances are Treasurer issues.

Escrow estimate differs A lender’s monthly escrow calculation is not the same as the county’s actual bill.

Do not appeal only because the tax bill is high. First determine whether the dispute concerns the appraised value, tax rate, special assessment, credit, payment posting or delinquency.

Read official tax-calculation guidance Open property records

Map and parcel research

Use GIS without treating map lines as a survey

Micro steps for map search

Find the written parcel record first Copy the parcel number before opening the map.

Open the Butler County GIS viewer Search or navigate to the property location.

Click the parcel polygon or line The viewer can display parcel data for the selected feature.

Compare the parcel ID Confirm that the map and written property report refer to the same record.

Use buffers or nearby-parcel tools carefully Map search supports parcel buffering and property-report or mailing-list exports.

Use legal sources for boundaries Move to the deed, plat, survey or appropriate professional before making a boundary decision.

Map questions and the correct verification source
Question	GIS can help with	Final verification
Where is the parcel?	General location, road and nearby parcel context.	Parcel number and written property record.
Who owns the nearby lot?	Selecting the neighbouring parcel.	Auditor record and recent Recorder deed.
Where is the exact boundary?	Approximate visual location.	Recorded survey, plat and licensed surveyor.
Can a fence or driveway be placed here?	Initial parcel context.	Survey, easement, zoning and permit review.
Can I export a map?	PNG, GIF, JPG, BMP or PDF map output and custom size.	Export is for research, not legal certification.
Can I create a mailing list?	Buffer or selected-parcel export where available.	Review permitted use and current ownership data.

Boundary warning: Do not position a fence, building, driveway, utility or easement from an online GIS line. Parcel layers can be offset from surveyed ground monuments.

Open current GIS viewer Open Auditor map search

Market and buyer research

Use Sales Search and Advanced Search meaningfully

A nearby sale is not automatically comparable. Match the location, property, transaction and valuation date before using a sale for pricing or a Board of Revision complaint.

Match the location

Hamilton, Middletown, Fairfield, Oxford or comparable local market
Same township, city or tax-district context
Similar road access and neighbourhood
Comparable school-district influence

Match the property

Residential, commercial, industrial, farm or vacant use
Similar building size and age
Similar condition and grade
Similar lot size and improvements

Match the transaction

Recent date near the valuation date
Normal market exposure
No related-party or gift transfer
No foreclosure or partial-interest distortion

Exclude misleading transfers

Family or gift transfer

Trust or estate transfer without market exposure

Recorded-document research

Find deeds, mortgages, liens and easements

The Auditor property card shows parcel information. The Recorder search provides the recorded instruments affecting ownership, mortgages, liens, easements, releases and other land-record matters.

Search the Recorder correctly

Copy clues from the Auditor property record Save the current owner, former owner, transfer date, parcel number and any book, page or instrument reference.

Open the official Recorder search Choose Quick Search or Advanced Search.

Search the grantor or grantee Try full names, initials, prior surnames, trusts, estates and business names.

Choose the search scope Use Index Only for indexed fields or Index & Full Text for OCR searching within document images.

Narrow by date or document type Use the approximate recording date, deed, mortgage, lien, release or easement type.

Open and compare the image Confirm names, recording date, document number and legal-description clues.

Check the certified-through date A very recent filing may not yet appear in the public index.

Index-only versus full-text/OCR search

Search Index Only

Searches information specifically indexed by Recorder staff, such as names, document types and numbers.

Search Index & Full Text

Also searches OCR-recognised words within document images. It can find more references but may produce imperfect text matches.

Two-word search behaviour: The Recorder search says each word is searched individually. Narrow the date range or document type when a common two-word name creates too many results.

Online images and copy requests

The Recorder reports that its imaging project is complete and records can be accessed online, including by book and page. When an image or index is unavailable, copy requests can be sent to Recorder@bcohio.gov.

Published copy help: The Recorder says up to five requested records may be emailed free per day. Requests above five are listed at $2 per page. Confirm the current policy before submitting a large request.

Credits, exemptions and farmland

Check Homestead, owner occupancy and CAUV separately

Which Butler County tax programme may apply?
Programme	Main purpose	Important requirement	Action
Owner-Occupancy Credit	Reduction associated with qualifying owner-occupied residential property.	The home must be the owner’s principal residence.	Review DTE 105C and current county instructions.
Homestead Exemption	Property-tax relief for qualifying homeowners.	Age, disability, veteran, surviving-spouse, ownership and income rules may apply.	Use the correct current Homestead application.
CAUV	Values qualifying agricultural land according to agricultural use.	Agricultural acreage or qualifying agricultural-income rules must be met.	Initial application plus annual DTE 109A renewal.
Damaged Property	Requests value consideration after qualifying damage or destruction.	Date, cause and extent of damage must be documented.	Review current DTE 26 filing requirements.

Homestead Exemption

For tax year 2026, based on the applicant’s 2025 Ohio adjusted gross income, the Butler County Auditor lists the ordinary income limit as $41,000. Age, disability, ownership, principal-residence and grandfathering rules can also affect eligibility.

Mailing route: Butler County Auditor, Attn: Homestead, 130 High Street, 3rd Floor, Hamilton, OH 45011. Verify whether in-person, mail or another current submission option applies before sending original documents.

Owner-Occupancy Credit

Owner occupancy is separate from Homestead. A homeowner may qualify for owner-occupancy treatment without qualifying for the age-, disability- or income-based Homestead programme.

After a sale or move: Do not assume the prior owner’s credit remains attached to the property. Check the current parcel and submit the appropriate owner-occupancy form when required.

CAUV farmland

Common eligibility routes

At least 10 acres devoted to qualifying commercial agricultural use
Or smaller acreage meeting the applicable agricultural-income test
Qualifying use must be documented
Rural appearance alone does not create eligibility

Use the Butler County Recorder’s official public-record search. It supports indexed searches and full-text OCR searches for deeds, mortgages, liens, easements and other recorded documents.

What is the Butler County Homestead income limit for 2026?

The Butler County Auditor lists a 2026 Homestead income limit of $41,000 based on the applicant’s 2025 Ohio adjusted gross income. Other eligibility and grandfathering rules may apply.

When can I file a Butler County Board of Revision complaint?

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.
