Indianapolis Property Tax Records

Indianapolis property tax records are managed through Marion County, where the Assessor and Treasurer offices handle everything from assessed values to tax bill payments for Indiana's state capital and largest city. Whether you own a home in Broad Ripple, a commercial building downtown, or a rental property on the south side, searching your parcel, checking your assessment, or paying what you owe can all be done online without a trip to the City-County Building at 200 E. Washington Street.

Marion County Assessor and Online Property Search

The Marion County Assessor is Joseph P. O'Connor, who brings over 25 years of experience and holds a Level III certification. His office works to apply fair and equitable assessments to homes and businesses across Indianapolis. Under IC 6-1.1-4, all real property in Indiana is assessed at its true tax value as of January 1 each year, and O'Connor's office is responsible for carrying out that standard across every parcel in Marion County.

The main tool for searching Indianapolis property tax records is the Assessor's online portal at indy.gov. You can search by address, parcel number, or owner name to pull up current assessed values. The portal also links to property record cards, which show the data the Assessor used to arrive at the assessed value: square footage, construction type, year built, and other features. A second interactive tool at maps.indy.gov/AssessorPropertyCards/ lets you browse property cards on a map. Both are free and open to the public.

The Assessor's main office is at 200 E. Washington Street, Room W121, Indianapolis, IN 46204. Phone: (317) 327-4907. Email: assessor@indy.gov. Hours are 8 a.m. to 4:30 p.m., Monday through Friday. A satellite office is also available at 7128 Waldemar Drive for residents who find the downtown location less convenient.

Indianapolis Property Tax History Reports

For a deeper look at what a parcel has paid over the years, use the Property Tax History Reports tool at indy.gov/activity/property-tax-history-reports. This tool shows payments, amounts billed, and any outstanding balances going back multiple tax years. It is useful when buying or selling property in Indianapolis, since it lets you see whether a parcel has any delinquent amounts before closing. Lenders also use this data when reviewing title work.

History reports are public records under IC 6-1.1-22, which governs the property tax billing and collection process in Indiana. The law sets May 10 and November 10 as the standard due dates for spring and fall installments statewide, including Indianapolis. If a due date falls on a weekend or holiday, it moves to the next business day.

Paying Indianapolis Property Taxes

Barbara Lawrence has served as Marion County Treasurer since January 1, 2021, and brings nearly 25 years of public sector finance experience to the role. Her office handles all property tax collections for Indianapolis. The Treasurer's office is at 200 E. Washington Street, Suite 1001. The mailing address for payments sent by mail is PO Box 6145, Indianapolis, IN 46206-6145. Phone: (317) 327-4771. Email: mytaxes@indy.gov.

To pay your Indianapolis property tax by phone, call 317.327.4TAX (4829) or toll-free at 1-888-881-8986. Phone payments are available around the clock. Online payments go through the same system. An eCheck payment costs $1.95 flat plus $0.95 per transaction. Paying by credit card costs $1.95 plus 2.5% of the payment amount. For those who prefer to pay in person without waiting in line, a drop box is available on the first floor of the City-County Building and accepts payments during and after business hours.

Penalties apply when payment is late. Under Indiana law, a 5% penalty applies within the first 30 days after the due date. After 30 days, the penalty rises to 10%. If an account remains unpaid long enough, it can be certified to the Auditor for tax sale proceedings. Keeping your Indianapolis property taxes current avoids those extra costs.

Property Tax Deductions for Indianapolis Homeowners

Indiana's deduction system under IC 6-1.1-12 gives Indianapolis homeowners several ways to reduce their property tax bill. The homestead deduction is the most common. It applies to your primary residence and reduces the assessed value used to calculate your tax. A supplemental homestead deduction provides a second layer of relief on top of the standard amount. Both must be filed with the Marion County Auditor.

Seniors age 65 or older who meet income and property value thresholds can apply for the Over 65 deduction. A separate Over 65 Circuit Breaker credit caps property tax as a percentage of income. Blind or disabled homeowners and totally disabled veterans have their own deduction categories. Homeowners who installed geothermal or solar energy systems may also qualify for a deduction. Applications must be filed by January 5 to take effect for the following tax year. The Auditor's Office is in the City-County Building at the same Washington Street address.

Appealing Your Indianapolis Property Assessment

If you think the assessed value of your Indianapolis property is too high, you have the right to appeal. The first step is to review your property record card and look for factual errors. Wrong square footage, incorrect construction type, or features the Assessor listed that don't exist on your property are all common issues that can be corrected quickly. Call the Assessor at (317) 327-4907 or email assessor@indy.gov to start the informal review process.

If the informal review doesn't resolve the issue, you can file a formal appeal using Form 130 with the Marion County Property Tax Assessment Board of Appeals (PTABOA). The appeal deadline is June 15, which falls 45 days after Form 11 notices are mailed by April 30. The right to appeal is established under IC 6-1.1-35. If you disagree with the PTABOA's decision, the next level is the Indiana Board of Tax Review, and after that, the Indiana Tax Court. Most Indianapolis property owners resolve their appeals at the PTABOA level or through the informal review before it.

O'Connor's Goals for Indianapolis Assessments

Assessor O'Connor has made it clear that two things drive his office: expediting the appeals process and creating greater transparency. Both goals matter in a city the size of Indianapolis, where tens of thousands of property owners interact with the assessment system each year. His office has worked to make more data available online so that property owners can review their information before deciding whether to appeal.

Indianapolis uses a mass appraisal model, meaning the Assessor applies uniform methods across large groups of similar properties rather than conducting individual appraisals. Under IC 6-1.1-4, the Assessor must use the methods prescribed by the Indiana Department of Local Government Finance. The DLGF sets the rules and reviews county compliance, so Indianapolis assessments follow the same framework as every other Indiana county, applied at a much larger scale.

Tax Sale and Delinquent Property in Indianapolis

Delinquent Indianapolis property tax accounts go through a structured process before they reach tax sale. The Treasurer certifies unpaid accounts to the Auditor by July 1. The Auditor then adds them to the tax sale list if payment is not received. Property owners can stop the sale by paying the full delinquent amount, including penalties and costs, before the sale date. Marion County holds its tax sale each fall. The Indiana Gateway at gateway.ifionline.org is a good place to check delinquency status for any Indianapolis parcel before taking action.

Tax sale purchasers acquire a lien, not the property itself. The original owner has a redemption period under Indiana law to pay off the lien and keep the property. Only if the redemption period passes without payment can the purchaser move toward a tax deed. This process is the same statewide and applies to all Indianapolis parcels that go through a tax sale.
