Marion County Property Tax Appeal, Indiana

Travis BunnTravis Bunn·Updated July 24, 2026

Marion County is Indiana's most populous county and economic hub, home to Indianapolis, the state capital and largest city. With a 2026 population estimated at approximately 994,000, Marion County is the center of the 11-county Indianapolis-Carmel-Greenwood metropolitan area. The county's median home value of approximately $207,000 to $235,000 is above the Indiana average, and its effective property tax rate of 1.19% exceeds both the state median of 0.85% and the national median of 1.02%. The median annual property tax bill of $2,525 is slightly above the national median of $2,400, making property tax appeals an important savings opportunity for homeowners facing aggressive assessments driven by the county's rapid growth in healthcare, logistics, and technology sectors.

On the typical Marion County home, valued near $207,000 at the county’s effective tax rate of 1.19%, an over-assessment of even 10% means you are overpaying year after year until you appeal it. Here is how to find out if yours qualifies.

How Marion County Assesses Property

100%of market value

Assessed by: Marion County Assessor's Office

Assessment cycle: annual

Notices typically mailed: April-May (spring)

Indiana assesses property at 100% of market value, meaning your assessed value equals your home's fair market value. If your home's market value is $207,000 (Marion County's median), at Indiana's 100% assessment ratio your assessed value would be $207,000. After applying the standard homestead deduction of $40,000 (for 2026) and the supplemental 40% deduction on the remaining $167,000 ($66,800), your taxable assessed value would be approximately $100,200, resulting in approximately $1,192 in annual taxes at the county's effective rate of 1.19%.

The Appeal Process

Appeals are heard by the Property Tax Assessment Board of Appeals (PTABOA). PTABOA hearings are informal proceedings held monthly at the City-County Building. Each hearing lasts approximately 15-30 minutes, during which you present evidence, the assessor responds, and the five-member board deliberates. Written determinations are mailed within 8-10 business days.

1

Step 1: Receive your Form 11 Notice of Assessment in the spring (typically mailed by April 30). Review the assessed value and property details carefully for accuracy.

2

Step 2: Gather evidence to support your appeal, including comparable sales from the past 12 months, recent appraisal reports, photographs of property condition issues, repair estimates for deferred maintenance, and proof of incorrect property data (square footage, age, condition).

3

Step 3: Complete and file Form 130 (Taxpayer's Notice to Initiate an Appeal) with the Marion County Assessor's office within 45 days of receiving your Form 11, or by June 15 of the assessment year, whichever is later. State your current assessed value, your opinion of the correct value, and specific reasons for disagreement.

4

Step 4: Attend an informal review conference with the assessor's office. Most appeals are resolved at this stage through negotiation. Bring all evidence and be prepared to discuss comparable properties and market conditions.

5

Step 5: If the informal review doesn't resolve your appeal, your case is forwarded to the Property Tax Assessment Board of Appeals (PTABOA) for a formal hearing. The board will schedule a hearing, typically lasting 15-30 minutes, where you present your evidence.

6

Step 6: If you disagree with the PTABOA decision, you can appeal to the Indiana Board of Tax Review (IBTR) by filing Form 131 within 45 days of receiving the PTABOA determination.

7

Step 7: As a final option, if the IBTR denies your appeal, you may appeal to the Indiana Tax Court within 45 days of the IBTR's final determination.

Frequently Asked Questions

What is the deadline to appeal my property taxes in Marion County for the 2026 tax year?
For properties assessed on January 1, 2025 (payable in 2026), the appeal deadline is June 15, 2026, or 45 days from the date your Form 11 assessment notice is mailed, whichever is later. If your Form 11 was mailed before May 1, 2026, your deadline is June 15, 2026. If mailed after April 30, you have exactly 45 days from the mailing date. This is a strict statutory deadline with no extensions, missing it means you forfeit your right to challenge that year's assessment. Mark your calendar immediately upon receiving your assessment notice and gather evidence early.
How do I file a property tax appeal online in Marion County?
Marion County offers online appeal filing through the official Indy.gov website and the Indiana Gateway portal. To file online, visit www.indy.gov/activity/appeal-assessment and complete Form 130 (Taxpayer's Notice to Initiate an Appeal) electronically. You'll need your parcel number, current assessed value, and your opinion of the correct value. Upload supporting evidence such as comparable sales, photos, or appraisal reports as PDF attachments. After submission, you'll receive a confirmation number and the assessor's office will contact you to schedule an informal review conference. Keep copies of all submitted materials and confirmation emails for your records.
What is the homestead exemption worth in Marion County in 2026?
Marion County homeowners receive Indiana's homestead deduction, which for 2026 assessments includes a $40,000 standard deduction plus a 40% supplemental deduction on the remaining assessed value. For a home assessed at $207,000 (the county median), this results in a $40,000 deduction plus an additional $66,800 deduction (40% of the remaining $167,000), reducing taxable value to $100,200. This saves approximately $1,271 annually at the 1.19% effective tax rate. Additionally, all homesteads automatically receive a new 10% credit (up to $300) on the final tax bill. Combined, these benefits can reduce your property tax bill by over $1,500 annually compared to non-homestead properties.
What happens at a PTABOA hearing in Marion County?
The Property Tax Assessment Board of Appeals (PTABOA) conducts informal hearings monthly at the City-County Building in downtown Indianapolis. Hearings are scheduled for approximately 15-30 minutes and follow a structured format: you present your evidence for 5-10 minutes, the assessor's representative responds for 5-10 minutes, and the five-member board deliberates for about 5 minutes. You should bring all evidence including comparable sales data, photographs, appraisal reports, and documentation of property defects. The atmosphere is less formal than court, and most property owners represent themselves successfully. The board issues a written determination within 8-10 business days by mail. If you disagree with the decision, you have 45 days to appeal to the Indiana Board of Tax Review.
How much can I save by appealing my property taxes in Marion County?
Potential savings depend on how much your assessment exceeds your property's actual market value. With Marion County's 1.19% effective tax rate, every $10,000 reduction in assessed value saves approximately $119 annually in property taxes. For a home incorrectly assessed $50,000 too high, a successful appeal could save $595 per year. Given Marion County's recent aggressive assessment increases, the assessor added $5.5 billion to commercial and industrial values for 2025 alone, many residential properties face similar over-assessments. Properties in rapidly gentrifying neighborhoods or those affected by broad trending adjustments often see the largest reductions. Homeowners with strong comparable sales evidence regularly achieve 10-20% assessment reductions, translating to $200-$500 in annual savings for median-value homes.
What evidence do I need for a successful Marion County property tax appeal?
The strongest Marion County appeals include recent comparable sales of similar properties sold within the past 12 months and within one mile of your home. Indiana law places the burden of proof on you to demonstrate the assessed value doesn't equal market value, so comparable sales are critical. Additionally, provide a professional appraisal dated near January 1 of the assessment year, photographs documenting deferred maintenance or property defects, contractor estimates for needed repairs, and proof of any incorrect property characteristics like wrong square footage or age. Marion County uses trending methodology that applies neighborhood-wide factors, so evidence showing your property differs from neighborhood averages is particularly persuasive. Organize evidence chronologically and clearly demonstrate how it supports your proposed value.
Can I appeal my Marion County property taxes if my assessment didn't change?
Yes, you can appeal your property assessment even if the value remained the same from the prior year, as long as you believe the current assessed value exceeds your property's true market value. Indiana law allows appeals whenever the assessment doesn't reflect fair market value, regardless of whether it changed. This is particularly relevant in Marion County where market values may decline in certain neighborhoods while assessments remain static. File Form 130 within the standard deadline (June 15 or 45 days from your Form 11 notice) and provide evidence that market conditions, property deterioration, or other factors mean your current assessment is too high. However, if your assessment increased by more than 5% from the prior year, the burden of proof shifts to the assessor to justify the increase.
What if I miss the June 15 appeal deadline in Marion County?
Missing Marion County's appeal deadline is serious, Indiana law provides no extensions or late filing exceptions for Form 130 appeals. Once the 45-day window or June 15 deadline passes, you cannot challenge that assessment year. However, you have options: you can still appeal the following year's assessment when you receive your next Form 11 notice, and you should immediately file for any missing exemptions like the homestead deduction which can reduce your tax bill going forward. Additionally, if you discover an objective factual error (wrong square footage, incorrect property classification, or missing exemption), contact the assessor immediately as corrections to factual errors may be possible outside the normal appeal window. For future years, set a reminder to review your assessment notice immediately upon receipt and file within 30 days to avoid missing the deadline.
