Grant County Property Tax Appeal, Indiana

Travis BunnTravis Bunn·Updated July 22, 2026

Grant County is located in central Indiana with a population of approximately 66,500 residents. The county seat is Marion, the largest city with about 28,200 residents. Other notable communities include Gas City, Upland, Jonesboro, Fairmount, and Van Buren. Grant County's median home value of $105,800 is significantly below the state median of $123,100, and its effective property tax rate of 0.85% is also lower than both the Indiana median of 1.01% and the national median of 1.02%. This makes Grant County one of the more affordable counties in Indiana for property taxes, though appeals remain important for homeowners who believe their assessments are incorrect.

On the typical Grant County home, valued near $105,800 at the county’s effective tax rate of 0.85%, 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.

2026 Appeal Deadline: June 15, 2026, or 45 days from the date your Form 11 assessment notice is mailed, whichever is later

Indiana law gives property owners 45 days from the date their Form 11 (Notice of Assessment) is mailed to file an appeal. In most cases, Form 11 notices are mailed in April or early May, making the standard deadline June 15. However, if your notice is dated after May 1, your deadline extends to 45 days from that mailing date. This deadline is strictly enforced with no extensions granted.

How Grant County Assesses Property

100%of market value

Assessed by: Grant County Assessor's Office

Assessment cycle: annual

Notices typically mailed: April-May

Indiana assesses all property at 100% of market value using annual trending adjustments. The county applies mass appraisal techniques and updates values each year based on recent sales data. For example, if your home's market value is $105,800 (the county median), at Indiana's 100% assessment ratio your assessed value would be $105,800. After applying the standard homestead deduction of $40,000 and the supplemental deduction of 40% on the remaining value ($26,320), your taxable assessed value would be approximately $39,480, resulting in approximately $336 in annual taxes at the county's effective rate of 0.85%.

The Appeal Process

Appeals are heard by the Property Tax Assessment Board of Appeals (PTABOA). PTABOA hearings in Grant County are informal, typically lasting 20 minutes. Sign-up is first-come, first-served starting at 8:30 AM on hearing days. You will present your evidence directly to the board, and the assessor may respond. The board issues a written determination (Form 115) after the hearing.

1

Step 1: File Form 130 with the Grant County Assessor's Office within 45 days of receiving your Form 11 assessment notice (typically by June 15, 2026). Include your property information, the assessed value you're appealing, your opinion of the correct value, and reasons for the appeal.

2

Step 2: Attend a preliminary informal meeting or phone conference with an assessor's office representative. This informal review resolves many appeals without a formal hearing. Bring comparable sales data, photos, appraisals, or other evidence supporting your claimed value.

3

Step 3: If the informal review does not resolve your appeal, your case will be scheduled for a formal hearing before the Grant County Property Tax Assessment Board of Appeals (PTABOA). PTABOA hearings are typically held later in the year (often October-December) and last approximately 20 minutes.

4

Step 4: If you disagree with the PTABOA's determination (Form 115), you may appeal to the Indiana Board of Tax Review (IBTR) by filing Form 131 within 45 days of receiving the PTABOA's decision. The IBTR conducts a state-level administrative hearing.

5

Step 5: If the IBTR rules against you, you may appeal to the Indiana Tax Court within 45 days by filing a petition. This is a formal judicial proceeding and typically requires legal representation.

6

Step 6: As a final option, you may appeal an unfavorable Tax Court decision to the Indiana Supreme Court, though this is rare and discretionary.

Frequently Asked Questions

What is the deadline to appeal my property taxes in Grant County for 2026?
The deadline to file a property tax appeal in Grant County is June 15, 2026, or 45 days from the date your Form 11 assessment notice is mailed, whichever is later. Most Grant County homeowners receive their assessment notices in April or early May, making June 15 the standard deadline. However, if your notice is dated after May 1, you have 45 days from that mailing date. This is a hard deadline enforced by Indiana law with absolutely no extensions granted for any reason, including vacation, not receiving the notice, or computer problems.
How do I file a property tax appeal in Grant County?
To file a property tax appeal in Grant County, you must complete Form 130 (Taxpayer's Notice to Initiate an Appeal) and submit it to the Grant County Assessor's Office at 401 S. Adams Street, 5th Floor, Marion, IN 46953. You can file in person during office hours (8 AM - 4 PM, Monday-Friday), by mail, or by email to assessor@grantcounty.in.gov. Include your property information, the assessed value you're appealing, your opinion of the correct value, and reasons for disagreement. After filing, you'll be scheduled for an informal review with assessor staff, and if that doesn't resolve the issue, a formal PTABOA hearing will be scheduled.
What is the homestead exemption worth in Grant County?
The homestead exemption in Grant County consists of two parts for 2026: a standard deduction of $40,000 off your assessed value, plus a supplemental deduction of 40% of the remaining value after the standard deduction is applied. For a home assessed at the county median of $105,800, the standard deduction removes $40,000, leaving $65,800. The supplemental deduction then removes 40% of that ($26,320), leaving a taxable value of just $39,480. At Grant County's 0.85% effective tax rate, this saves approximately $563 annually compared to paying taxes on the full assessed value. The homestead exemption is the single most valuable property tax benefit available to Grant County homeowners.
What happens at a Grant County PTABOA hearing?
A Grant County PTABOA (Property Tax Assessment Board of Appeals) hearing is an informal proceeding that typically lasts about 20 minutes. Hearings are held at the Grant County Complex, 5th Floor Assessor's Office at 401 S Adams Street in Marion. You can sign up starting at 8:30 AM on a first-come, first-served basis, with sign-ups closing at noon. You'll present your evidence (comparable sales, photos, appraisals) directly to the board and explain why your assessment is incorrect. The assessor's office may respond to your claims. After the hearing, the PTABOA issues a written determination (Form 115), usually within several weeks. If you disagree with their 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 Grant County?
The average successful property tax appeal in Grant County saves approximately $650 per year, according to available data. However, your actual savings depend on how much your assessment is reduced and your property's tax rate. For example, if you successfully reduce your assessed value by $50,000 and your property is in an area with a 1.0% tax rate, you would save $500 annually. With Grant County's median effective rate of 0.85%, a $50,000 reduction saves about $425 per year. These savings repeat annually until the next reassessment, so a one-time successful appeal can save thousands of dollars over time. Keep in mind that not all appeals succeed, but the process is free and there's no risk of your assessment increasing in Indiana.
What evidence do I need for a Grant County property tax appeal?
The most effective evidence for a Grant County property tax appeal includes recent comparable sales of similar properties in your area (at least 3 properties sold within the last 12-18 months), a recent professional appraisal dated within the assessment year, and photographs documenting your property's condition, damage, or needed repairs. You should also obtain your property record card from the assessor's office to check for errors in square footage, year built, number of bedrooms/bathrooms, or other features. Repair estimates from licensed contractors, evidence of environmental issues, and market listings showing properties similar to yours priced below your assessment are also valuable. Indiana law does not require a professional appraisal, and comparable sales are often the most persuasive evidence for residential appeals.
Can I appeal my Grant County property taxes if I bought my home recently?
Yes, you can appeal your Grant County property tax assessment even if you recently purchased your home, and your purchase price may be strong evidence in your favor. If you bought the property in an arm's-length transaction (not from a family member or in a distressed sale) within the assessment year, your purchase price is considered excellent evidence of market value as of that date. However, be prepared to explain any differences between your purchase price and the assessed value, such as changes in the market, special financing, or property condition changes since purchase. File Form 130 with the Grant County Assessor within 45 days of receiving your assessment notice, and include your closing statement (HUD-1 or settlement statement) as key evidence.
What is the veteran property tax exemption in Grant County worth in 2026?
Grant County offers several veteran property tax benefits starting with the 2026 assessment year. Veterans with 100% disability ratings receive a complete property tax exemption with no limit on home value, meaning they owe zero property taxes on their primary residence. Partially disabled wartime veterans receive a $350 annual credit, while partially disabled veterans age 62 or older receive an additional $250 credit (maximum $600 combined). Additionally, veterans with 50% or higher disability ratings can receive a deduction equal to their disability percentage (e.g., a 70% disabled veteran receives a deduction of 70% of their home's assessed value). These new benefits, established by House Bill 1210 signed in March 2026, are significantly more generous than previous programs and have no home value caps. Applications must be filed with the Grant County Auditor's office by December 31 annually.
