Find the Marion County Assessment Record and Trace It to the Tax Bill

For property in Indianapolis and Marion County, the Assessor’s Property Report Card is the best starting point. It lets you search by address, owner, 7-digit county parcel number or Indiana’s 18-digit state parcel number and then review land, improvements and assessed value.

This page is assessment-first. It explains what the numbers on the property card mean, why Indiana uses 100% market value-in-use rather than a percentage assessment ratio, how “2025 Pay 2026” tax records work, and when to move from the Assessor to the Auditor, Treasurer, Recorder or GIS.

State check: this article covers Marion County, Indiana, including Indianapolis. There are Marion Counties in Florida, Oregon, Tennessee, Ohio and other states, and their property systems are completely different.

Quick answer: begin with the Marion County Property Report Card

Use the official Marion County Assessor Property Cards application. You can search by a 7-digit county parcel number, 18-digit state parcel number, owner name or property address. Once you open the correct card, save both parcel numbers before moving to taxes, deductions, GIS, deeds or an assessment appeal.

1 Search Address, owner or parcel number.
2 Verify Match address and parcel identifiers.
3 Read Land, improvements and assessed value.
4 Route Tax, deduction, deed, map or appeal.

Choose the Marion County property record you actually need

Indianapolis and Marion County split property work among several offices. The Assessor controls value records; the Auditor handles deductions and tax-accounting functions; the Treasurer handles payments; and the Recorder maintains recorded land documents.

Search troubleshooting

If the Marion County property search does not find the record

Address is not appearing? Start typing the street information and select the official suggested address rather than typing an unrecognized full address and moving on.
Owner search is too broad? Add more of the owner, trust or business name only after the first search returns too many results.
County parcel fails? Confirm that you are using the 7-digit Marion County number rather than the longer Indiana state parcel.
State parcel fails? Check the 18-digit number carefully. Marion County’s state parcel begins with county code 49.
Condo or multi-unit address looks incomplete? Verify the individual unit and parcel. Indy.gov warns that some multi-unit search results may not reflect the individual unit correctly.
Vacant land is difficult to locate? Search MapIndy by parcel or use a parcel number from a deed, prior tax bill or recorded document.
Ownership looks outdated? Use the Assessor card for assessment research, then confirm legal ownership through the Recorder when a deed question matters.
Still stuck? Call the Marion County Assessor at 317-327-4907 and have the property address and any parcel number available.

Indiana valuation rule

Marion County does not use a 19%, 35% or other partial assessment ratio

Indiana assessment target: 100% market value-in-use

Indiana’s assessment system is designed so assessed values reflect market value-in-use. The Department of Local Government Finance reviews county ratio studies to test whether assessments are accurate and uniform.

That makes Indiana different from states where the assessor first finds market value and then applies a fixed percentage such as 19% or 35% to produce assessed value.

Practical reading rule: if a Marion County Property Record Card shows a $300,000 total assessed value, do not multiply it by another statewide assessment percentage. Tax deductions, the taxing-district rate, credits and constitutional tax caps enter later in the tax calculation.

Annual adjustment and the new reassessment cycle

Indiana updates assessed values through annual adjustment using market data. The state also began a new four-year cyclical reassessment period on July 1, 2026 for taxes beginning with the 2026 Pay 2027 cycle.

Annual adjustment Counties submit ratio studies comparing assessed values with sale prices so DLGF can review assessment accuracy and equity.
2026 reassessment cycle Beginning July 1, 2026, assessing officials are scheduled to inspect roughly 25% of parcels in their jurisdiction each year over four years.
Physical inspection is not a tax bill A field review checks property characteristics used in valuation. Tax billing remains a later step.
The year label explained

What “2025 Pay 2026” means on an Indiana property-tax record

Indiana property taxes are paid in arrears. A tax bill paid in 2026 generally uses the property’s 2025 assessment. That distinction explains why the year on the Assessor card and the year you physically make the payment can look one year apart.

1
Jan. 1, 2025 Assessment date for the 2025 value used in the 2025 Pay 2026 cycle.
2
2024 sales Indiana guidance says 2024 market sales were used in determining 2025 Pay 2026 assessed values.
3
2025 assessment The Assessor establishes the gross assessed value.
4
May 11, 2026 Spring installment due date.
5
Nov. 10, 2026 Fall installment due date.
September 2026 status: the spring installment deadline has passed. The regular fall 2026 installment is due November 10, 2026. If a spring balance remains unpaid, use the live Treasurer record rather than the original coupon amount because penalties may apply.
Tax-record math

Estimate the path from gross assessed value to property tax

Indiana property-tax estimator

Enter the gross assessed value, total deductions and local tax rate shown on the tax record. Choose the property’s general constitutional cap category to compare the estimated gross tax with the basic cap threshold.

Referendum charges and other items can sit outside the ordinary constitutional cap. This calculator is for understanding the record—not replacing the official Treasurer bill.
Net assessed value $200,000
Gross tax estimate $4,000
Basic cap threshold $3,000

Net AV = gross AV − deductions. Gross tax estimate = net AV ÷ 100 × local tax rate. Basic cap = gross AV × selected cap percentage.

Indiana property-tax cap categories
Property class
General cap
What the cap means
Homestead / owner-occupied residence
1%
Eligible taxes are generally capped through a circuit-breaker credit at 1% of gross assessed value.
Other residential and agricultural land
2%
General constitutional cap is 2% of gross assessed value.
Other real and personal property
3%
General constitutional cap is 3% of gross assessed value.
The cap is not the tax rate. Indiana still calculates local rates by taxing district. A circuit-breaker credit applies when eligible taxes exceed the constitutional threshold, while voter-approved referendum charges can be outside the cap.
Treasurer records

Use the tax system when you need a balance, payment or cash-history record

Current tax balance or payment

The official payment workflow lets you search by property address or parcel number and make a one-time full or partial payment using the payment methods offered by the live system.

Search and pay property taxes
Tax payment history

Use the Cash History Report when the question is what was paid in a prior tax year rather than what is currently assessed.

View property cash history

After opening the tax-payment search

Choose address or parcel search If you do not know the parcel number, find it on the Assessor Property Record Card first.
Keep an address search broad Indy.gov recommends using a partial street name and, when needed, a partial owner name rather than an over-specific search.
Open the correct tax account Match the property address and parcel before reviewing the amount.
Confirm the tax year Do not mistake an old paid year for the current installment.
Check escrow before paying If a mortgage company normally pays the taxes, confirm whether the current installment has already been scheduled or paid.
Save the payment confirmation Keep the transaction details and later verify posting through the official record when proof of payment matters.

Cash History Report micro-steps

Search by property address or county parcel The address field uses official suggestions; select the correct result.
Check the populated owner and parcel Do not continue if the system selected the wrong property.
Select the tax year Choose the year you actually need to research.
View the report Use the resulting history to distinguish prior payments from the current tax balance.
Auditor records

If the assessed value looks right but the tax is high, check deductions

A missing deduction can raise taxable value even when the Assessor’s gross value is correct. Marion County provides a separate deduction search administered through the Auditor side of the property-tax process.

Open the current deduction search Begin with the property address.
Select the correct official address suggestion The system should populate the owner name and Parcel ID.
Verify the parcel Pay special attention to condos and multi-unit properties so you do not review a neighboring unit or the overall building.
Review deductions already attached to the property Compare the result with the deduction section of the current tax bill.
Contact the Auditor when a qualifying deduction is missing Keep the parcel number, ownership information and any prior application confirmation available.
Search current property deductions Marion County Auditor
Mortgage Deduction warning: Indiana’s current tax-bill guidance states that the Mortgage Deduction is no longer available beginning with 2023 Pay 2024. Do not rely on an older property-tax article that still treats it as a current deduction.
MapIndy

Use MapIndy when the parcel location matters more than the tax number

MapIndy can search properties by address or parcel, show mapped property context and link users back to the Property Record Card. It also provides boundaries, imagery, measurement tools and connections to other Indianapolis GIS applications.

Parcel location Search a property and visually confirm that the Assessor record points to the tract you intended to research.
Historic and aerial context MapIndy provides basemaps and imagery that can help explain surrounding development and location.
Related map tools IndyGIS also links to zoning, government profile, stormwater, surveyor and other location-specific applications.

Do not treat a GIS parcel line as a survey. Indianapolis GIS states that its data is for general informational and graphic-representation purposes and does not represent a legal document.
Assessment review

Appeal the assessed value—not simply the size of the tax bill

Indiana’s assessment appeal process begins with the local assessing official. A taxpayer uses Form 130 to identify why the current assessed value or an objective property-record issue should be changed.

Subjective assessment issue

Examples include disagreement over grade, condition, market value or other valuation judgment. Marion County also provides an online workflow for subjective appeals.

Objective record issue

Examples can include a clerical error, wrong person, incorrect property description, missing or incorrect deduction/credit, or another factual issue listed by Indiana DLGF.

General Indiana Form 130 path

Review the Property Record Card and Form 11 Identify the exact assessment year and the specific value or factual record you dispute.
Collect property-specific evidence Useful evidence can include comparable sales, photographs, measurements, closing documents or an appraisal when relevant.
Initiate the local appeal File Form 130 or use the applicable Marion County online appeal workflow.
Participate in the local review The local assessing official reviews the appeal and may hold an informal conference.
PTABOA review if unresolved A denied or unresolved appeal can proceed to the Marion County Property Tax Assessment Board of Appeals.
State review after the local process Eligible PTABOA decisions can be appealed to the Indiana Board of Tax Review.
Deadline rule: Indiana generally uses June 15 when a Form 11 or Form 11-A is issued. If no Form 11 is mailed and the tax bill serves as the assessment notice, different timing can apply. Check the date and instructions on the actual notice rather than assuming a deadline from another county.
Marion County 2026 verification: the DLGF Form 11 status table currently lists Marion County’s contact number but does not publish a Marion County Form 11 mail date or deadline in the table. Use the notice you received and confirm timing with the Assessor before filing.
An appraisal is not automatically required. Indiana’s taxpayer guidance says an owner may appeal an assessment without first obtaining a professional appraisal, although a relevant appraisal can still be strong evidence.

10 Marion County-specific answers

Marion County tax assessment search and records FAQs

1. What is the official Marion County, Indiana tax assessment search?

Use the Marion County Assessor Property Cards application at maps.indy.gov. It lets you search by 7-digit county parcel number, 18-digit Indiana state parcel number, owner name or property address.

2. What is the difference between Marion County’s county parcel number and state parcel number?

The Assessor search accepts a 7-digit Marion County parcel number and an 18-digit Indiana state parcel number. Marion County state parcel numbers begin with county code 49 and may appear in a hyphenated format.

3. Does the Marion County Auditor determine the assessed value?

No. The Marion County Assessor maintains property cards and assessed values. The Auditor handles property-tax deductions, tax-accounting work and related real-estate administration.

4. Is Marion County property assessed at only a percentage of market value?

Indiana assessments are designed to reflect 100% of market value-in-use. Do not apply another 19%, 35% or similar statewide assessment ratio to the total assessed value shown on a Marion County Property Record Card.

5. What does “2025 Pay 2026” mean on a Marion County tax record?

Indiana property taxes are paid in arrears. The 2025 assessed value is generally used for taxes payable during 2026, which is why an assessment year and payment year can differ.

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

Indiana’s 2026 property-tax installment dates are May 11, 2026 and November 10, 2026. Use the Marion County Treasurer’s live tax search to verify the current balance, especially if the spring installment was not paid by May 11.

7. How can I see past Marion County property-tax payments?

Use the official Property Cash History Report. Search by property address or county parcel number, confirm the populated owner and parcel, select the tax year and open the resulting history report.

8. What should I do if a building or property detail on the Assessor card is wrong?

Document the specific factual error with measurements, photographs, permits, plans or other reliable evidence and contact the Marion County Assessor. Indiana Form 130 also provides a route for objective property-record issues.

9. How do I appeal a Marion County assessed value?

Start with the Marion County Assessor using the applicable Form 130 or online appeal workflow. Indiana generally uses June 15 filing rules tied to the assessment notice, but you should follow the date and instructions on your actual Form 11 or tax notice and confirm timing with the Assessor.

10. Can MapIndy show the legal boundary of my Marion County property?

MapIndy is useful for parcel context and property research, but Indianapolis GIS states that its map data is informational and does not represent a legal document. Use recorded plats, deeds and a professional survey when an exact legal boundary matters.

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.
