Marion Card County Property Assessor 2026: Search & Records

Indianapolis • Marion County Indiana Property Cards

Search Marion County Assessor Property Cards, Values, Maps & Tax Records

Marion County Assessor Joseph P. O’Connor maintains Indianapolis and Marion County assessment records. The county’s official Property Report Card tool is the best starting point when you need an owner name, assessed value, parcel number, property characteristics or a printable assessor card.

The search accepts a 7-digit county parcel number, an 18-digit Indiana state parcel number, owner name or property address. MapIndy adds parcel mapping and aerial context, while Treasurer services handle the current tax bill and Recorder services handle deeds, mortgages, liens and other recorded documents.

This 2026 guide shows exactly how to search and read a Marion County property card, distinguish county and state parcel IDs, understand Indiana’s 100% market-value-in-use assessment standard, check deductions and constitutional tax caps, handle the now-passed 2026 assessment appeal period, prepare for the November 10 property-tax installment and verify deeds or liens before making a property decision.

What Marion County Property Owners Should Check Now

The normal 2026 real-property assessment appeal period has passed. Indiana’s 2026 Form 11 cycle used June 15 as the regular filing deadline when the notice was issued before May 1. A 2026 assessment affects taxes generally payable in 2027.
Spring 2026 tax installment May 11, 2026 has already passed. If unpaid, use the live Treasurer workflow because a penalty may now apply.
Fall installment November 10, 2026 is the next statewide Indiana property-tax due date.
2026 reassessment work Indiana’s new four-year cyclical reassessment period began July 1, 2026, with roughly one-quarter of parcels physically reviewed each year.
2025 Pay 2026 vs 2026 Pay 2027: Indiana property taxes are paid in arrears. The tax bill you pay in 2026 generally reflects the prior assessment year. A January 1, 2026 assessment normally feeds the bill payable in 2027.
Indianapolis property records involve four elected offices

Assessor vs Auditor vs Treasurer vs Recorder

Assessor — Joseph P. O’Connor Property cards, assessed value, real/personal property assessment, parcel characteristics and assessment appeals.
Auditor — Julie Voorhies Homestead and other deductions/credits, property transfers and tax-account administrative functions.
Treasurer — Barbara A. Lawrence Current tax bill, tax payment, delinquent amounts and property tax collection.
Recorder — Kate Sweeney Bell Deeds, mortgages, liens, releases and other permanently recorded real-estate documents.
Property card is not a tax receipt or title report. Use the Assessor card for assessment facts, the Treasurer for money due and the Recorder for controlling recorded documents.

Two parcel identifiers appear in Marion County

7-Digit County Parcel vs 18-Digit State Parcel Number

County Parcel Number The Assessor search expects a 7-digit local parcel identifier, such as 1234567.
State Parcel Number Indiana’s standardized parcel identifier contains 18 digits and can appear formatted with hyphens and decimal points. Marion County numbers begin with county code 49.
Save both identifiers when shown. Some Indy systems work best with the county parcel number, while state/local property databases can reference the standardized Indiana parcel number.
Read the card before you appeal or pay

What to Check on the Marion County Property Report Card

Card item What it tells you Why it matters
Parcel Number Local county property identifier. Use it to connect the card to tax and mapping systems.
State Parcel Number Indiana standardized parcel identifier. Useful for state-level and recorded-property cross-checks.
Owner Owner carried in assessment/GIS records. Use Recorder deed records when legal title is important.
Property Class Residential, commercial, industrial, agricultural or another assessment classification. Classification affects assessment methodology and tax-cap allocation.
Land Assessed Value Assessment allocated to the land component. Compare with neighborhood land trends and parcel characteristics.
Improvement Assessed Value Assessment allocated to structures/improvements. Incorrect size, condition or improvement data can distort assessment.
Total Assessed Value Combined gross assessed value before deductions. Feeds the property-tax calculation.
Neighborhood Mass-appraisal grouping or neighborhood reference. Useful for comparable-sale and annual trending context.
Acreage / Legal Description Assessment/GIS description of the parcel. Use the deed or survey for legally controlling boundaries.

Six Checks Before You Rely on a Marion County Property Card

Parcel Exact match
Address Verify situs
Owner Check deed
Land Review acreage
Building Check details
Total AV Review year
Property card does not prove a legal boundary. MapIndy and Assessor parcel graphics are public-information tools. Use recorded surveys, plats and professional boundary work where exact location matters.
Indiana assessment ratio = 100%

How Marion County Property Assessment Works

Indiana’s annual ratio-study system targets property assessments at 100% of market value-in-use. The Assessor does not apply a 35%, 25% or other fractional assessment ratio like some other states.

Market value-in-use Indiana’s valuation standard asks what the property is worth in its current use under state assessment rules.
Annual adjustment Assessments are trended each year so the assessment roll remains aligned with market evidence.
Mass appraisal Neighborhood, sales and property-characteristic data are used across many similar parcels.
Assessment ≠ tax bill. A $300,000 gross assessed value does not mean the owner pays a fixed percentage chosen by the Assessor. Deductions, local tax rates, credits, circuit-breaker caps and referendum charges all affect the bill.
New statewide cycle began July 1, 2026

Indiana’s 2026–2030 Cyclical Reassessment

Indiana’s new four-year statewide cyclical reassessment began July 1, 2026. County and township assessing officials are expected to physically inspect roughly 25% of parcels each year.

2026–27 Approximately one-quarter of the jurisdiction receives inspection/data review.
2027–28 Next group of parcels moves through the physical reassessment cycle.
2028–29 Additional neighborhoods/property classes are inspected.
2029–30 Four-year physical-review cycle is completed.
What an inspector checks: building size, garage, pool, additions, demolitions and other physical characteristics that can affect the property record card.
Physical inspection is not the only time value changes. Indiana still performs annual trending/adjustment between field inspections.
Form 130 starts the county assessment appeal

Marion County Property Assessment Appeals in 2026

August 12, 2026: the regular June 15 deadline associated with the normal 2026 assessment notice cycle has passed.
Review the Property Report Card first. Check square footage, building type, condition, land, garage, basement and other objective facts.
Compare market evidence. Use relevant sales, a recent purchase, appraisal or other evidence supporting your requested value.
Use Form 130 to initiate the county appeal. Indiana’s current appeal form is the Taxpayer’s Notice to Initiate an Appeal.
Observe the deadline printed on the notice. When Form 11 is mailed before May 1, Indiana law generally sets June 15 as the deadline for that assessment year.
Participate in the county review. Appeals can move through informal review and then Marion County’s Property Tax Assessment Board of Appeals.
Use Form 131 for the next state level. A taxpayer dissatisfied with the PTABOA determination can appeal to the Indiana Board of Tax Review under the state process.
Missed the ordinary deadline? Certain specific assessment errors can have different correction procedures. Contact the Assessor instead of assuming every problem can be fixed with a late ordinary market-value appeal.
Indiana Property Tax Appeal Forms Use state-prescribed Form 130/131 procedures and verify the assessment-year deadline before filing.
Auditor handles deductions and credits

Marion County Homestead & Property Tax Deductions

Indiana property-tax deductions generally reduce assessed value before the local tax rate is applied. Credits reduce the tax liability itself. Applications go through the Marion County Auditor, not the Assessor.

Standard Homestead Primary-residence benefit for qualifying owner-occupied property.
Over 65 State benefits can include an Over 65 Deduction/Credit and circuit-breaker protections when eligibility rules are met.
Disabled Veteran Indiana provides property-tax benefits for qualifying veterans meeting statutory disability/service rules.
Blind / Disabled Qualifying taxpayers can seek the corresponding state property-tax benefit.
Mortgage Indy.gov continues to provide a mortgage-related deduction/application workflow where applicable under current law.
Marion County option credit Indiana DLGF maintains a county-option circuit-breaker credit category specifically applicable to Marion and St. Joseph counties.
Application timing: Indiana DLGF says a deduction/credit filed by the applicable January 15 deadline applies to the tax bill due that year. A new 2026 owner seeking a benefit for taxes payable in 2027 should verify the January 15, 2027 deadline with the Auditor.
Do not re-file every year unnecessarily. Indiana says taxpayers generally do not need to reapply annually unless ownership, title or qualifying use changes.
Marion County Property Tax Deductions Use Indy.gov for current Homestead and other deduction workflows.
Indiana constitutional circuit-breaker system

1% / 2% / 3% Property Tax Caps

1% cap Homestead property receives a circuit-breaker cap based on 1% of gross assessed value.
2% cap Other residential property and agricultural land generally fall under the 2% category.
3% cap Other real property and business personal property generally fall under the 3% category.
The caps do not mean your local tax rate is 1%, 2% or 3%. The local tax rate is calculated separately. Circuit-breaker credits reduce liability above the constitutional cap.
Referendum taxes can sit outside the normal cap. Voter-approved referendum charges can cause a bill to exceed the simple 1%/2%/3% calculation.
Gross AV → deductions → rate → credits → cap

How Marion County Property Tax Is Calculated

1. Gross Assessed Value Land + improvements at Indiana’s market-value-in-use standard.
2. Net Assessed Value Subtract qualifying deductions.
3. Local Tax Rate Net Assessed Value ÷ 100 × tax-district rate.
4. Credits / Caps Apply local/state credits and circuit-breaker limitation where eligible.
Indiana rates are quoted per $100 of net assessed value. If the certified rate were $3.00, the basic gross calculation would use Net AV ÷ 100 × 3.00 before applicable credits and caps.
Do not publish one universal Marion County rate. Tax rates vary by taxing district, school corporation, township, municipality and voter-approved obligations.

What Happens If Marion County Property Tax Is Paid Late?

Indiana DLGF states that taxpayers who miss a property-tax due date receive a statutory penalty.

Still unpaid after 30 days The penalty increases to 10% of the unpaid tax under the statewide framework.
Use the live Treasurer account before paying a late installment. Do not mail only the amount printed on an older tax statement if a penalty is already due.
Business tangible personal property

Marion County Business Personal Property in 2026

Indiana businesses can have taxable tangible personal property separate from the real estate. Examples include equipment, machinery, furniture, fixtures and similar business assets.

Search the relevant party/document. Trace deeds, mortgages, liens, releases and other recorded instruments.
Compare recording information with the property card. Assessment ownership can lag or display differently from the legal deed.
Request an official copy when needed. Use Recorder procedures rather than screenshots from the property-card map for a legal or closing matter.
Assessment ownership is not a title search. For liens, easements, title defects, inheritance disputes or closing decisions, use recorded-document review and qualified title/legal professionals.

Marion County Assessor Property Card FAQs

1. How do I search a Marion County Indiana property card?

Use the official Indianapolis/Marion County Assessor Property Cards application at maps.indy.gov. You can search by a 7-digit County Parcel Number, 18-digit State Parcel Number, all or part of the Owner Name, or property Address. Open the matching result to view the Property Report Card.

2. Who is the Marion County Assessor in 2026?

Joseph P. O’Connor is the current Marion County Assessor. Indy.gov lists him among the current elected Indianapolis and Marion County officials. The Assessor’s public property-assessment telephone number is 317-327-4907.

3. What is the difference between the county parcel number and state parcel number?

The Marion County property-card tool uses a 7-digit local County Parcel Number. It also allows an 18-digit Indiana State Parcel Number, which is the standardized statewide parcel identifier and normally begins with county code 49 for Marion County.

4. What information is shown on a Marion County property card?

The property card can help identify the parcel, owner, property location, land and improvement assessment, total assessed value, property classification, acreage, legal-description information and building characteristics. The exact fields depend on the property type and available assessment data.

5. Is Marion County property assessed at 100% of market value?

Indiana’s assessment ratio target is 100%. County assessments are intended to reflect market value-in-use under Indiana property-assessment rules, with annual trending and ratio-study review used to keep values aligned with the market.

6. What was the 2026 Marion County property assessment appeal deadline?

Indiana’s regular 2026 appeal deadline was June 15 when the Form 11 notice was mailed before May 1. The ordinary 2026 filing period has therefore passed as of August 2026. Form 130 is the state form used to initiate a county property-assessment appeal.

7. When are Marion County Indiana property taxes due in 2026?

Indiana’s statewide property-tax due dates for 2026 are May 11 and November 10. The spring deadline has passed, and November 10, 2026 is the next regular installment deadline. Property tax payments are made to the Marion County Treasurer.

Indiana’s circuit-breaker system generally caps homestead property taxes at 1% of gross assessed value, other residential property and agricultural land at 2%, and other real and personal property at 3%. Voter-approved referendum taxes can be outside the normal cap calculation.

9. Where do I check Marion County Homestead Deduction information?

Property-tax deductions and credits are administered through the Marion County Auditor. Indy.gov provides online deduction workflows, while Indiana DLGF publishes the statewide eligibility rules and forms. Do not use the Assessor property card alone to determine whether a deduction has been correctly applied to the current tax bill.

10. Where do I search Marion County deeds and liens?

Use the Marion County Recorder’s official recorded-document search workflow on Indy.gov. The Recorder maintains deeds, mortgages, liens, releases and other real-estate documents. Start with the owner and parcel information from the Assessor card, then verify the controlling recorded instrument through Recorder records.

County Property Search, Homestead & Tax Help Toolkit

Use this free helper to find the right county office, prepare a property search, understand appraised value, review homestead exemption steps, and organize TRIM notice or tax bill questions before using official county websites.

Built for Florida county property guides
Helps users find official resources
No fake database or approval claim
Useful after every article

Find the Correct County Office

Property Appraiser, Tax Collector, Clerk, GIS, and VAB offices do different jobs. Pick your task below.

Quick rule: Property Appraiser = value, records, parcel details, exemptions. Tax Collector = bill and payment. Clerk/Recorder = deeds and recorded documents. VAB = formal value disputes.

Official Property Search Helper

Use this when a county article tells you to search by owner, address, parcel number, folio, PCN, STRAP, or alternate key.

Search tip: If address search fails, try only the house number and main street name. Avoid typing Street, Avenue, Road, Drive, unit numbers, or punctuation unless the official portal requires it.

Homestead Exemption Readiness Check

This helps homeowners prepare before filing through the official county Property Appraiser website.

Important: This is not an eligibility decision. The official county Property Appraiser decides approval, required documents, late filing options, and exemption status.

TRIM Notice & Value Review Helper

Use this to organize your questions before calling the Property Appraiser or preparing an appeal.

Your preparation checklist

Value term Simple meaning
Market value The appraiser’s estimate of the property’s value as of the assessment date.
Assessed value The value after limits or caps may be applied.
Exemptions Approved reductions such as homestead or other exemptions.
Taxable value The value used by taxing authorities after exemptions.

Property Tax Bill Direction Helper

The Property Appraiser values property, but the Tax Collector usually handles the actual bill and payment.

Florida timing reminder: Many Florida tax bills are mailed around November and become delinquent if unpaid after March 31. Always verify exact dates, discounts, and payment fees with the official county Tax Collector.
