Marion County Property Tax Records

Marion County property tax records cover Indianapolis and all townships in the consolidated city-county government. The Marion County Assessor and Treasurer maintain these records and offer online tools for searching assessed values, looking up parcel data, viewing property cards, and paying tax bills. This page covers how to access Marion County property tax records, who leads the key offices, what payment options are available, and how the appeal process works for property owners who want to challenge an assessed value.

Marion County Assessor's Office

The Marion County Assessor is Joseph P. O'Connor. O'Connor has more than 25 years of property tax assessment experience and holds a certified level III Indiana assessor/appraiser credential. The main office is at 200 E. Washington Street, W121, Indianapolis, IN 46204. Phone is (317) 327-4907. Email is assessor@indy.gov. A satellite office is located at 7128 Waldemar Drive for taxpayers who find the downtown location less convenient. The assessor's job is to apply fair and equitable assessments to all homes and businesses in Marion County.

To search for a Marion County assessed property value, use the online lookup tool at indy.gov. The property card viewer is at maps.indy.gov/AssessorPropertyCards/. These tools let you pull up assessed values, parcel data, ownership records, and the full property record card for any parcel in Marion County. The property card includes the building description, land data, and the assessment history going back several years. This is useful for homeowners checking their own value, buyers researching a property, or anyone who wants to understand how a particular assessment was calculated.

Marion County Treasurer and Tax Payment Options

The Marion County Treasurer is Barbara Lawrence. Lawrence brings nearly 25 years of public sector finance and administration experience to the office. The main office is at 200 E. Washington St., Suite 1001, Indianapolis. Phone is (317) 327-4444. Email is mytaxes@indy.gov. Mailed payments go to Marion County Treasurer, P.O. Box 6145, Indianapolis, IN 46206-6145. A drop box is available on the first floor of the City-County Building for after-hours payments.

Marion County offers several ways to pay property taxes. In person at the treasurer's office during regular business hours is one option. By mail with a check and payment stub is another. Online payment is available through the city's portal, with fees that vary by method. An eCheck costs $1.95 plus $0.95 per transaction. A credit card costs $1.95 plus 2.5% of the payment amount. For taxpayers paying large bills, the eCheck fee is significantly lower than the card fee. You can also pay by phone at 317.327.4TAX, which is 317-327-4829, or toll-free at 1-888-881-8986.

Spring taxes are due May 10. Fall taxes are due November 10. Missing a due date brings a 5% penalty for the first 30 days, then 10% after that. Marion County is subject to the same statewide billing rules under IC 6-1.1-22 that govern all Indiana counties. Extended non-payment can result in a tax lien and eventual sale under IC 6-1.1-24.

How Marion County Assesses Property Values

Marion County property is assessed as of January 1 each year under IC 6-1.1-4. The standard is 100% of market value. With hundreds of thousands of parcels across Indianapolis and the surrounding townships, Marion County runs one of the largest assessment operations in Indiana. Residential properties are valued primarily using comparable sales. Commercial parcels use income or cost methods depending on the property type. Industrial properties follow cost approaches when market data is limited.

The assessor's team reviews sales disclosures filed whenever a property changes hands. These disclosures feed into the sales comparison analysis that drives assessed values for residential properties. When many sales occur in a neighborhood, the assessor has strong data to work with. In areas with fewer sales, the office may rely more on modeling and cost data. Marion County taxpayers who want to understand why a value changed year to year can request an explanation from the assessor's office at (317) 327-4907 before filing a formal appeal.

Appealing a Marion County Assessed Value

Marion County taxpayers who disagree with their assessed value can appeal by filing a Form 130 petition. The typical deadline is June 15 of the assessment year. The Marion County Property Tax Assessment Board of Appeals, the PTABOA, conducts hearings and issues written decisions. If the PTABOA ruling does not satisfy the taxpayer, an appeal to the Indiana Board of Tax Review is the next step.

Good appeal evidence in Marion County includes recent comparable sales of similar properties in the same area. The assessor's property card search at maps.indy.gov makes it easier to pull recent sale prices for similar homes nearby. The Indiana DLGF at (317) 232-3777 provides appeal forms and explains the full process. The DLGF also maintains a statewide assessed value lookup that covers every Marion County parcel and lets you cross-check a value before deciding whether to appeal. For income-producing properties, rent rolls and cap rate analysis are the most persuasive tools at a hearing.

Marion County Property Tax Deductions

Marion County property owners can apply for Indiana's standard deductions at the assessor's or auditor's office. The homestead deduction reduces the assessed value of a primary residence and includes both a standard deduction and a supplemental homestead credit under IC 6-1.1-12. Apply by January 5. You only need to file once, but if ownership changes you must refile.

Other Marion County deductions include the mortgage deduction, the over-65 deduction for seniors meeting income and value thresholds, and deductions for blind or disabled homeowners. Veterans with a 100% service-connected disability rating can qualify for a full property tax exemption on their primary residence. The surviving spouse of a qualifying veteran may also apply. Indiana's circuit breaker caps limit total taxes in Marion County to 1% of assessed value for homesteads, 2% for other residential, and 3% for all other property types. Checking whether all applicable deductions are on file is worth a quick call to the assessor at (317) 327-4907.

Online Property Search and GIS Tools

Marion County offers a well-developed set of online tools for property research. The assessed value finder at indy.gov covers all parcels in the county. The property card map viewer at maps.indy.gov/AssessorPropertyCards/ lets you browse parcels geographically and click through to detailed records. The Beacon GIS platform provides an alternative search route with its own mapping interface. The Indiana Gateway Taxpayer Portal shows budget and levy data for Indianapolis and the township taxing units that make up a Marion County tax bill.
