Rob HartleyRob Hartley·Updated February 16, 2026

Marion County, Indiana's most populous county, contains the city of Indianapolis and serves as the state capital. With a median home value of $186,900, Marion County's property tax burden is significant. The county's effective property tax rate of 1.19% is significantly higher than the national median of 1.02%, though residents pay a median annual tax bill of $2,361, which is slightly below the national median of $2,400. Recent assessments have seen dramatic increases, with the Marion County Assessor's Office collectively increasing assessed values for apartment complexes by nearly $2 billion. These increases make property tax appeals especially important for homeowners seeking relief from rising tax bills.

In Indiana, properties are assessed at 100% of their market value, meaning your assessed value equals your market value before any deductions are applied. For example, if your home's market value is $186,900 (the county median), at Indiana's 100% assessment ratio your assessed value would be $186,900, resulting in approximately $2,224 in annual taxes at the county's effective rate of 1.19% before any exemptions.

Frequently Asked Questions

What is the deadline to appeal my property taxes in Marion County?
The deadline to appeal your property taxes in Marion County is June 15, 2026, for the 2026 assessment year. Unlike most Indiana counties, Marion County taxpayers receive their official notice of assessment increases through their spring tax bills rather than separate assessment notices. Keep in mind that property tax appeals are generally only accepted in a 1-3 month window each year, so it's crucial to file by the deadline. Missing this deadline means losing your right to appeal for that tax year.
How do I file a property tax appeal in Marion County online?
You can file your appeal online through the Marion County assessor's website, at any assessor's office location, or by mail to the Marion County Assessor Appeals Department at 200 E. Washington Street, Suite 1360, Indianapolis, IN 46204-3319. To begin, call the Marion County Assessor's Office at(317) 327-4907 and ask for a property tax appeal form. The online process can be completed in 5 minutes or less, making it the most convenient option for many homeowners.
What is the homestead exemption worth in Marion County?
The standard homestead deduction in Marion County is 60% of your assessed valuation or $45,000, whichever is less. Additionally, the homestead credit amount equals up to 25% (17% state, 8% county) of your gross tax according to current Indiana code, depending on your taxing district. Applications completed by January 15th will reflect on the current year's tax bill, so an application completed by January 15, 2026 will be reflected on the tax bill issued in Spring of 2026. You need to re-file for the homestead deductions when you make changes to your title, such as adding or removing an owner.
What happens at a PTABOA hearing in Marion County?
At a Property Tax Assessment Board of Appeals (PTABOA) hearing in Marion County, you'll present your evidence to support why your property assessment should be lowered. You'll need to provide sufficient proof that your property is overassessed, including valuations of similar homes nearby as evidence. The assessor's office should be able to show their work by explaining the data and methodologies applied to determine each estimate of value. The county typically will take several weeks to months to process the appeal after your hearing.
How much can I save by appealing my property taxes in Marion County?
Successful appeals lower tax bills by $700 on average across the country. In Marion County, where the average property tax bill went up by 8% over the past year and the assessor expects next year's bill to be 10% more than that, the potential savings can be significant. With the county's median home value of $186,900 and effective tax rate of 1.19%, even a modest reduction in assessed value could save hundreds of dollars annually. If your appeal is accepted, your home assessment and property taxes will be lowered as a result.
What evidence do I need for a Marion County property tax appeal?
For a Marion County property tax appeal, you'll need to submit sufficient proof that your property is overassessed, including valuations of similar homes nearby as evidence. For apartment complexes, Indiana law requires assessors to calculate value using three approaches (cost, sales comparison, and income capitalization) and apply the lowest of the three. Strong evidence includes recent comparable sales in your neighborhood, photos documenting property condition issues, professional appraisals, and repair estimates for any deferred maintenance. Indianapolis taxpayers should review their assessments and tax bills to ensure the assessor's valuations are consistent with Indiana law and the factors impacting the property's value.
Why did my Marion County property tax assessment increase so much in 2026?
For 2026 assessments, Indiana's Department of Local Government Finance eliminated a downward adjustment (called a Verified Economic Multiplier) that previously applied to the Indiana cost tables, which resulted in substantial increases in base costs. Because these base costs are typically the starting point for calculating a property's assessed value in Indiana's mass appraisal system, it affected most properties' final assessed value. For apartment complexes alone, the Marion County Assessor's Office has collectively increased assessed values by nearly $2 billion. These increased costs will be reflected in Spring 2026 tax bills.
Can seniors get additional property tax relief in Marion County?
Yes, seniors over 65 years old can get a discount on homes worth less than $200,000 in Marion County. However, with rising home prices meaning many seniors may be priced out of this benefit, as the average home in Marion County will be worth about $165,000 next year, the county assessor suggested lawmakers should consider expanding eligibility. Additionally, Indiana provides a property tax liability credit to freeze the homestead property tax liability for low income seniors. Contact the Marion County Assessor's Office for specific eligibility requirements and application procedures for all senior exemptions.
