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.

Do not use one office for every property question. The Assessor controls assessed value, the Auditor administers deductions and tax-record functions, the Treasurer controls payments and balances, and the Recorder controls recorded land documents.

Quick answer: begin with the Property Report Card

Open the official Assessor Property Cards search, choose one search method, open the correct result and save both the local parcel number and 18-digit state parcel number before moving to maps, taxes, deductions, deeds or an assessment appeal.

1 Search broadly Use a parcel number, owner or suggested address.

2 Open the full card Review land, structures and assessed value.

3 Verify the parcel Match the address and both parcel identifiers.

Indiana property-office routing

Which Marion County office controls the record?

Correct office for each property task
What you need	Correct office or tool	What it provides	Important limit
Owner, parcel, assessed value or Property Record Card	Assessor Property Cards	Local and state parcel numbers, owner display, address, assessed value, land and improvement details.	The owner display is not a legal title opinion.
Parcel location, aerial image or nearby features	MapIndy	Parcel search, map layers, historic imagery, measurements, boundaries and printable maps.	Mapped parcel lines are not surveyed boundaries.
Property value correction or appeal	Assessor	Property-data review, assessment explanation, informal conference and Form 130 process.	The Treasurer cannot change assessed value.
Homestead, mortgage, veteran, senior or disability deduction	Auditor	Deduction lookup, application processing and eligibility guidance.	A deduction application is not a property-value appeal.
Current tax balance, payment or receipt	Treasurer	Online tax search, payment, posting status and delinquency information.	The Auditor and Assessor do not post tax payments.
Deed, mortgage, lien, release, easement or plat	Recorder	Recorded-document index, copies and recording services.	A basic online index is not a complete title examination.
Tax-sale property research	Treasurer and Tax Sale Viewer	Tax-sale map context, parcel information and county instructions.	The map warns that properties and conditions can change.
Government, school or voting jurisdiction	My Government Jurisdictions	Jurisdiction information after selecting an official address suggestion.	A postal city alone may not identify every taxing unit.

Efficient sequence: Search the Assessor card, copy both parcel numbers, save the tax district and then contact only the office responsible for the next action.

Property Report Card search

Search by parcel, state parcel, owner or address

The official search provides four separate methods. Use one method at a time so an unnecessary field does not exclude the correct result.

Local parcel number

Find the local number on a Marion County tax bill or older property card.
Enter the seven digits.
Do not substitute the longer state parcel number.
Open the matching card.
Verify the property address.

Required format: 1234567

State parcel number

Copy the complete 18-digit identifier.
It normally begins with 49 for Marion County.
Try the number with the displayed hyphens first.
Check every zero and repeated digit.
Compare the returned local parcel number.

49-XX-XX-XXX-XXX.XXX-XXX

Owner name

Enter all or part of the owner name.
Begin with a surname or distinctive business word.
Try a trust, estate, LLC or former owner.
Review all plausible matches.
Confirm the address before opening the record.

Broad search works best first

Property address

Begin entering the property address.
Select the correct suggestion that appears.
Do not merely type the address and ignore the suggestion list.
Remove the unit or suffix if nothing appears.
Use MapIndy when the address is unclear.

Choose the suggested county address

Verify the result before using it

Open the complete Property Record Card The short result row does not show every assessment or property characteristic.

Match the physical address Do not confuse an owner’s mailing address with the property location.

Save both parcel numbers Marion County records may use the seven-digit local number or the 18-digit state number depending on the service.

Check the owner and property class Confirm that the result represents the intended residence, commercial property, apartment, land or exempt parcel.

Review assessed value and improvements Check land, buildings, total assessed value and the effective assessment year.

Move to the next official system Use MapIndy, the Treasurer, deduction search or Recorder only after confirming the parcel.

Search official Property Cards Open assessed-value instructions

Search troubleshooting

No property result? Use this recovery order

Owner search failed Use part of the surname or business name and try a spouse, former owner, trust, estate or LLC.

Address search failed Remove the unit, direction and street suffix, then select a result from the official suggestion list.

Local parcel number failed Confirm that you entered exactly seven digits and did not use the 18-digit state parcel.

State parcel failed Check the 49 prefix, hyphens, decimal placement and every zero.

The property recently sold Search the former owner and check the Recorder’s deed index.

A parcel was divided or combined Search each former parcel and ask the Assessor whether a new local number was created.

A condominium unit is missing Search the owner or state parcel number and verify the individual unit rather than the overall building.

The property is near the county line Confirm that the parcel is actually in Marion County rather than an Indianapolis postal address in another county.

Understand the Marion County Property Record Card

Important fields and what to check
Property field	What it represents	What to do next
Local parcel number	Marion County’s shorter internal parcel identifier.	Use it for the county’s tax and property systems when accepted.
State parcel number	Indiana’s longer standardized parcel identifier.	Save the complete 18-digit number for cross-system research.
Owner name	The ownership name displayed in the assessment database.	Use the recorded deed when legal ownership proof is required.
Property address	The physical or situs address associated with the parcel.	Compare it with MapIndy and the deed description.
Assessed land	The assessed-value portion assigned to the land.	Check acreage, neighborhood, classification and land influence.
Assessed improvements	The portion assigned to buildings and other taxable improvements.	Verify building size, grade, age, condition and features.
Total assessed value	The value used as the starting point for tax calculation before deductions and credits.	Do not confuse it with the final tax bill.
Property class	Residential, commercial, industrial, apartment, exempt or another recorded classification.	Contact the Assessor if actual use or classification is materially wrong.
Tax district	The combination of local taxing units and rates applying to the property.	Use My Government Jurisdictions to understand the listed units.
Legal description	An assessment-record description used to identify the land.	Use the Recorder’s deed and plat for legal work.

Check factual details before appealing value

Property facts to verify

Living area and building footprint
Year built and effective age
Basement and finished area
Bathrooms and bedrooms
Garage and accessory buildings
Land size and property class

Useful correction evidence

Current photographs
Measurements or floor plans
Permit and demolition records
Inspection reports
Repair estimates
Recorded deed or survey

Important distinction: A factual property-card correction and a market-value disagreement can use different evidence. Identify whether the problem is the data, the valuation or both.

MapIndy and IndyGIS

Use parcel maps, aerials and jurisdiction layers

MapIndy can search by address or parcel, connect to the Property Record Card, display boundaries and infrastructure, show historic basemaps and oblique imagery, measure features, add shapes or text and print a customized map.

MapIndy micro steps

Find the property card first Copy the local or state parcel number so the map does not depend only on an uncertain address.

Open MapIndy from the GIS hub Select the general online mapping application.

Search the parcel or address Open the property result and confirm the parcel number.

Choose only useful layers Turn on parcel, aerial, infrastructure, zoning or jurisdiction information as needed.

Use historic or oblique imagery carefully Imagery dates can differ, and a structure visible in one year may have changed.

Measure for planning only Map measurements are useful estimates but not a survey or legal setback determination.

Print the map with identifiers Include the address, parcel number, selected layers and date for your research file.

Which IndyGIS application should you use?
Question	Application	Important limit
Where is the parcel?	MapIndy	Verify the parcel number and do not treat the map line as surveyed.
What does the Assessor record show?	Property Report Cards	Assessment ownership is not a title opinion.
What zoning is displayed?	Indy Zoning Browser	Confirm official zoning and approvals before relying on it for development.
What is the stormwater billing area?	Stormwater Impervious Area	The application does not replace a billing determination or field measurement.
What government serves this address?	Government Profile or My Government Jurisdictions	Select the correct suggested address.
Is the property shown for tax sale?	Tax Sale Viewer	Status, improvements and sale eligibility can change.

Boundary and development warning: Do not locate a fence, driveway, addition, utility, setback or property corner from MapIndy alone. Use recorded documents, applicable zoning staff and a professional survey where necessary.

Search and pay through the official workflow

Open the Marion County tax-payment service Choose address search or parcel-number search.

Use a partial search The county recommends a partial street name and partial owner name rather than an over-specific entry.

Open the correct tax account Match the owner, property address, parcel number and tax year.

Check mortgage escrow Contact the lender before making a possible duplicate payment.

Review current installments, penalties and credits Do not assume the amount matches an older paper bill.

Choose the payment method The one-time service accepts ACH/eCheck and credit card payments; account options can provide additional wallet or account features.

Review any service fee Check the final amount before submitting the payment.

Auditor deduction workflow

Check Homestead and other property-tax deductions

A correct assessment can still produce an unexpectedly high bill when an expected deduction is missing. Check the current deduction record before deciding that the Assessor’s value is wrong.

Search deductions already attached to the property

Open the current deduction search Use the property address field.

Begin typing the address Wait for official address suggestions to appear.

Select the correct suggested property The owner name and parcel ID should populate automatically.

Submit the search Review the deductions shown for the selected parcel.

Check condominium or multi-unit records carefully Confirm that the result represents the individual unit rather than the overall building.

Save the deduction result Keep it with the tax bill and property card when contacting the Auditor.

Common Auditor-administered deductions

Property-tax deductions and preparation
Deduction	Typical purpose	What to prepare
Homestead	Primary-residence tax relief for a qualifying owner-occupied home.	Property address, parcel ID, owner information and required identity or residency details.
Mortgage	Deduction connected with a qualifying recorded mortgage.	Recorded mortgage information, lender and property identifiers.
Over 65	Relief for qualifying older homeowners under current income, value and ownership rules.	Age, ownership, residence and current financial documentation.
Blind or disabled	Relief for qualifying applicants meeting disability and other statutory requirements.	Medical or disability proof and property information.
Disabled veteran	Deduction for qualifying veterans or certain surviving spouses.	VA documentation, service information and ownership details.
Over-65 circuit breaker	Limits certain tax increases for qualifying older homeowners.	Age, residence, income and assessed-value documentation.

Eligibility changes over time. Do not rely on an old article’s dollar limit or deduction amount. Use the current Marion County application and confirm the applicable filing-year rules with the Auditor.

Homestead application micro steps

Confirm that the property is the primary residence A rental, second home or investment property does not qualify merely because the applicant owns it.

Open the official Homestead application Choose whether the submitter is the property owner or authorized representative.

Enter the property and applicant information Use the same owner and parcel information shown on the Property Record Card.

Form 130 and PTABOA

The ordinary 2026 appeal deadline has passed

2026 appeal deadline June 15, 2026

The ordinary Marion County filing date has passed.

Late issue Check the notice date

A later notice can create a different statutory window.

Next cycle Prepare evidence early

Do not wait until the final filing week.

An assessment appeal challenges assessed value or property-record facts. It does not directly challenge the tax rate, payment penalty or a missing deduction.

Identify the actual issue first

Wrong square footage or property feature Gather measurements, photographs, permits and the current Property Record Card.

Market value is too high Gather relevant sales, an appraisal, listing history and condition evidence.

Tax bill is high but value appears correct Review deductions, tax district, special assessments, penalties and credits.

Owner or mailing information is wrong Use the appropriate ownership, Recorder or mailing-address process instead of a valuation appeal.

Prepare a future Form 130 appeal

Save the current Form 11 notice The notice date controls the filing calculation in many cases.

Download the current Property Record Card Mark every fact you believe is incorrect.

State the value or correction requested A vague complaint that taxes are high is not a complete valuation argument.

Collect evidence tied to the assessment date Use comparable sales, appraisal evidence, photographs, measurements, income information or repair evidence.

File with the local Assessor Use the county’s current online process or Form 130 instructions.

Participate in the informal review The Assessor may recommend an agreement or forward the unresolved appeal to PTABOA.

Attend the PTABOA hearing when required Organize exhibits and keep proof of every submission.

Use Form 131 for a state appeal An eligible PTABOA determination can be appealed to the Indiana Board of Tax Review within the applicable deadline.

Evidence matched to the dispute

Strong assessment evidence
Assessment problem	Useful evidence	Weak approach
Recent purchase	Purchase agreement, closing statement, deed and transaction circumstances.	Submitting only a real-estate website estimate.
Incorrect building size	Measurements, plans, permits and photographs.	Claiming the card is wrong without identifying the correct measurement.
Poor condition	Dated photographs, inspections and contractor estimates.	Listing normal maintenance without market-impact evidence.
Comparable-sales argument	Similar arm’s-length sales near the assessment date.	Choosing only the lowest sales without adjustments.
Apartment or commercial income	Leases, rent roll, vacancy, expenses, capitalization support and appraisal.	Using residential comparisons for income-producing property.

Deadline warning: June 15, 2026 was the ordinary deadline for many Marion County 2026 appeals. A notice mailed later can create a different deadline, so read the specific Form 11 or other notice rather than assuming no remedy remains.

Question	Likely document	What to verify
Who received ownership?	Deed	Grantor, grantee, legal description and recording date.
Was a loan recorded?	Mortgage	Borrower, lender, amount and property description.
Was the mortgage released?	Satisfaction or release	Reference to the original mortgage and recording date.

Is there a recorded access or use right?	Easement or covenant	Benefited property, burdened property and legal description.
How was a subdivision laid out?	Recorded plat	Lot number, dimensions, easements and recording reference.

Title warning: Searching one owner name or one deed is not a complete title examination. Liens, easements, probate issues, unreleased mortgages and court matters can require professional research.

Ten practical answers

Marion County Indiana property FAQs

Does the Marion County Auditor operate the property search?

The main Marion County property-card search is operated through the Assessor and IndyGIS. The Auditor handles property-tax deductions, ownership-transfer processing, tax-duplicate responsibilities and other county financial duties.

How can I search Marion County Indiana property records?

Use the official Assessor Property Cards tool. It supports searches by seven-digit parcel number, 18-digit state parcel number, owner name and property address.

Why does my Marion County property search return no result?

Simplify the search. Use part of the owner name, select the address from the suggested list, remove street suffixes or search with the parcel number from a tax bill. A recently transferred, split or combined property may still appear under an older record.

Are MapIndy parcel boundaries legally exact?

No. MapIndy and assessment parcel lines are useful research tools but do not replace a recorded deed, subdivision plat, survey or professional boundary determination.

Who collects Marion County Indiana property taxes?

The Marion County Treasurer collects real estate and other property taxes. The Assessor determines assessed value, while the Auditor maintains deductions and performs other tax-administration duties.

What are Marion County Indiana’s 2026 property-tax due dates?

Indiana lists May 11, 2026 as the spring installment due date and November 10, 2026 as the fall installment due date. The spring deadline has passed, so taxpayers with an unpaid amount should verify the current balance and penalty through the Treasurer.

How can I check whether my Homestead Deduction is active?

Use the official Marion County deduction search. Begin typing the property address, select the correct suggested address and verify that the owner name and parcel ID populate before submitting.

How do I appeal a Marion County property assessment?

An assessment appeal begins with the Marion County Assessor, generally through Form 130 or the county’s online appeal process. Unresolved appeals proceed to the Property Tax Assessment Board of Appeals and may later be taken to the Indiana Board of Tax Review.

Where can I find Marion County deeds, mortgages and liens?

Use the Marion County Recorder’s Office and its remote land-record search services. Search with current and former owner names, document type, recording date, document number or other known recording information.

Where are the Marion County property offices located?

The principal Assessor, Auditor, Treasurer and Recorder services are located in the Indianapolis City-County Building at 200 East Washington Street, Indianapolis, Indiana 46204. Verify the office suite and public-counter hours before visiting.

Information checked August 6, 2026: Property-card search fields, MapIndy capabilities, elected officials, property-tax dates, online payment guidance, deduction tools, appeal procedure, Recorder contact information and office-routing details were checked against official Indianapolis, Marion County and Indiana government sources.

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.
