Indiana's Assessment System
Indiana reassesses annually and values property at 100% of market value in use. The assessed value on your Form 11 notice should reflect what your home would sell for on the open market.
Indiana uses a "trending" system where the county adjusts values annually based on local sales data. Full reassessments with physical inspections happen on a cycle determined by the county (typically every 4-6 years).
How to Appeal in Indiana
Step 1: Informal Conference (by June 15)
Request an informal conference with the county assessor by June 15. This is a meeting where you discuss your concerns and present evidence. The assessor may agree to adjust your value at this level.
Step 2: PTABOA (45 Days After Informal)
If the informal conference does not resolve your case, file a formal petition with the county Property Tax Assessment Board of Appeals (PTABOA) within 45 days of the assessor's informal decision. The PTABOA holds a hearing and issues a binding decision.
Step 3: Indiana Board of Tax Review
If the PTABOA denies your petition, appeal to the Indiana Board of Tax Review (IBTR) within 30 days. The IBTR conducts a de novo review (fresh review of all evidence).
Indiana Deductions (Exemptions)
Indiana calls its tax breaks "deductions" rather than exemptions. Key deductions include:
| Deduction | Benefit | Eligibility |
|---|---|---|
| Homestead Standard Deduction | 60% of assessed value (up to $45,000) or 60% of assessed value, whichever is less | Owner-occupied primary residence |
| Supplemental Homestead | Additional 35% on value between $600,000 and assessed value | Same as homestead |
| Mortgage Deduction | Up to $3,000 | Homestead property with a mortgage |
| Over 65 Deduction | Up to $14,000 or half of assessed value | Age 65+, income under limit, assessed value under limit |
| Disabled Veteran Deduction | Up to $37,440 (adjusted) | Veterans with disability rating |
The homestead deduction is the most valuable and must be filed by March 1 of the assessment year. If you own and live in an Indiana home and have not filed, you are overpaying significantly.
Indiana Tax Caps
Indiana has constitutional tax caps (called "circuit breakers") that limit your total property tax bill:
- Homestead: 1% of assessed value
- Residential rental and agricultural: 2% of assessed value
- All other property: 3% of assessed value
These caps mean your total property tax bill from all taxing entities combined cannot exceed the applicable percentage. If your calculated tax exceeds the cap, you receive a credit for the difference. The cap is applied automatically.
Frequently Asked Questions
What if my tax bill seems higher than 1% of my assessed value?
Check whether the circuit breaker credit was applied. It should appear as a credit on your tax bill. If your total tax exceeds 1% of assessed value and no credit is shown, contact the county auditor.
Can I file the homestead deduction late?
Indiana allows late filing in certain circumstances. Contact the county auditor to find out if you can file after the March 1 deadline.
Does selling my home trigger reassessment?
No. Indiana does not automatically reassess upon sale. Your assessment continues to be updated through the annual trending process regardless of ownership changes.
