How to Appeal Property Taxes in Indiana: Complete 2026 Guide
Indiana property owners can appeal their property tax assessment. The filing deadline is June 15. No public statewide success rate data available. Indiana PTABOAs and the Board of Tax Review do not publish aggregate appeal outcome statistics.
This comprehensive guide walks you through the entire Indiana property tax appeal process, from gathering evidence to presenting your case to the - First level: County Assessor.
⏰ Critical Indiana Appeal Deadlines
Filing window: Initial appeal (Form 130): Within 45 days after tax bill is mailed (typically June 15 in most counties)
Informal review period: Up to 180 days from filing to resolve
PTABOA hearing: Must be held within 120 days if not resolved informally
Appeal to Indiana Board of Tax Review: Within 45 days after PTABOA gives notice of determination
⚠️ Missing the deadline means waiting another year and paying higher taxes. Mark your calendar now!
Step-by-Step Indiana Appeal Process
Review Your Assessment Notice
Your assessment notice shows your property's taxable value. Look for the "assessed value" or "market value" – this is what you're appealing. Compare it to recent sales of similar homes in your neighborhood.
Gather Compelling Evidence
The - First level: County Assessor wants to see hard data, not opinions. Focus on:
- •Comparable sales: 3-5 similar properties that sold for less than your assessed value
- •Property condition: Photos and repair estimates documenting any issues
- •Assessment errors: Wrong square footage, features, or lot size
- •Market analysis: Evidence of declining values in your area
File Your Appeal Application
Submit your appeal to the - First level: County Assessor before the deadline. Most Indiana counties now offer online filing, but some still require paper forms. Include all your evidence with the initial filing when possible.
Prepare Your Presentation
If your appeal goes to a hearing, you'll typically have 5-15 minutes to present. Organize your evidence clearly, practice your key points, and prepare to answer questions about your property value.
Attend Your Hearing
Present your evidence professionally and stick to facts about market value. The board members are usually reasonable people – they just need solid evidence to justify a reduction.
What Makes Indiana's Appeal Process Unique
Indiana's constitutional tax caps create a unique dynamic where successful assessment appeals may yield no tax savings. If your property taxes already hit the cap (1% for homesteads), reducing the assessed value won't lower your tax bill - the circuit breaker credit simply adjusts. This makes Indiana one of the few states where winning an appeal might produce zero financial benefit.
The state's trending system adds another layer of complexity. Indiana uses a mass appraisal trending factor to adjust property values annually between general reassessments. Property owners can appeal both their base assessment and the trending factor applied, but must understand which component drives their value. Additionally, Indiana's 45-day deadline from tax bill mailing (not assessment notice) catches many off guard, as tax bills typically arrive in May with a June 15 deadline in most counties.
Assessment Cap/Protection
Indiana has constitutional property tax caps (circuit breaker credits) - among the strongest in the nation:
- 1% of gross assessed value for owner-occupied primary residences (homestead)
- 2% for other residential property, apartments, and agricultural land
- 3% for all other real and personal property
These caps were added to the Indiana Constitution in 2010 and provide automatic tax credits that reduce bills to the capped amount.
Required Filing Form
- Form 130: Petition for Review of Assessment (initial appeal)
- Form 131: Petition to the Indiana Board of Tax Review (for IBTR appeals)
- Form 115: Final Determination issued by PTABOA

Start Your Indiana AppealWhat Makes a Winning Appeal in Indiana
The - First level: County Assessor is looking for objective evidence that your property is overvalued. The strongest cases combine multiple types of evidence:
✓ Strong Evidence
- • Recent comparable sales (within 6-12 months)
- • Professional appraisals
- • Clear documentation of errors
- • Photos of property condition issues
- • Contractor repair estimates
✗ Weak Arguments
- • "My taxes are too high"
- • Old or distant comparable sales
- • Zillow estimates alone
- • General market opinions
- • Emotional appeals
Common Indiana Appeal Mistakes to Avoid
❌ Missing the deadline
Indiana has strict filing deadlines with no extensions. Set multiple reminders!
❌ Using weak comparables
Properties must be truly similar – same neighborhood, size, age, and condition
❌ Being unprepared
Board members ask questions. Know your evidence inside and out
❌ Getting emotional
Stay professional and factual. The board responds to data, not frustration
❌ Giving up after denial
Many successful appeals happen at the state level after local denial
💰 The Cost of Waiting
Every year you don't appeal is money left on the table. The average Indiana homeowner who successfully appeals saves $400-$1,200 per year. Over 10 years, that's $4,000-$12,000!

Indiana Tax-Saving Strategies Beyond the Appeal
A successful appeal is just one way to lower your Indiana property taxes. These additional strategies can stack with your appeal for maximum savings.
Strategy 1: Leverage the Constitutional 1% Cap
Indiana's constitution caps your homestead property taxes at 1% of assessed value (2% other residential, 3% commercial). This is the strongest cap in the nation -- your taxes can never exceed this percentage. But lowering your assessed value through appeal still reduces your bill within the cap.
Strategy 2: Claim the Standard Deduction ($48,000)
Indiana's standard homestead deduction is the lesser of 60% of assessed value or $48,000. For the median home, this removes $48,000 from assessed value. You must file for it -- it's not automatic. One-time filing stays on record unless you move.
Strategy 3: Apply for the Over-65 Deduction
Homeowners 65+ with income under approximately $40,000 get an additional deduction of up to $14,000. This stacks on top of the standard deduction.
Strategy 4: Challenge the Trending Factor
Indiana uses a "trending factor" multiplier to adjust assessments between reassessment years. If the trending factor overshoots actual market conditions, this is a valid appeal argument. Check your county's trending factor on the Indiana DLGF website.
Strategy 5: Review Your Form 11 Carefully
Your assessment notice (Form 11) shows assessed value, deductions applied, and estimated tax. You have 45 days from the postmark to appeal. Check that all deductions are applied -- sometimes the standard deduction or over-65 deduction is incorrectly removed.
2026 Indiana Law Changes Affecting Your Appeal
Recent legislative changes in Indiana may affect your property tax bill and appeal strategy.
Constitutional Property Tax Caps (1%/2%/3%)
Indiana's property tax caps are embedded in the state constitution (Article 10, Section 1), making them extremely durable:
- 1% cap: Homestead (owner-occupied primary residence)
- 2% cap: Other residential and agricultural land
- 3% cap: All other property (commercial, industrial, vacant)
Standard Deduction (Homestead)
Indiana's standard homestead deduction is the lesser of 60% of assessed value or $48,000. For the median Indiana home ($148,600), this deduction removes $48,000 from your assessed value. Combined with the 1% cap, this is very powerful. You must file for homestead deduction -- it is not automatic.
Over-65 Deduction
Homeowners 65+ receive an additional deduction of up to $14,000 on assessed value, subject to income limits of approximately $40,000. This stacks on top of the standard deduction and works within the 1% cap framework.
Form 11: Your Assessment Notice
Indiana mails assessment notices on Form 11. You have 45 days from the postmark date to file an appeal. The Form 11 shows your assessed value, deductions applied, and estimated tax. Review all three carefully -- sometimes deductions are incorrectly removed or not applied at all.
Trending Factor
Indiana uses a "trending factor" to adjust assessed values between full reassessment years. The trending factor is a multiplier applied to your base assessment to approximate current market value. If the trending factor overshoots market conditions, this is a valid appeal argument. Check your county's trending factor on the Indiana Department of Local Government Finance website.
