TL;DR
Indiana assessment notices arrive in March-April. The informal appeal deadline with the county assessor is June 15. Tax bills are due in two installments: May 10 and November 10.

If you need to understand when Do Property Tax Bills Come Out in Indiana? Key Dates and Deadlines, this is the place. Indiana reassesses annually and values property at 100% of market value in use.
If your deadline has already passed, check whether your state has a secondary appeal window. Some states allow filing with a higher court or board after the initial deadline. If no secondary option exists, start preparing now for next year's appeal so you are ready the moment your next notice arrives.
Indiana Property Tax Calendar
| When | What Happens | Your Action |
|---|---|---|
| January 1 (prior year) | Assessment date | Values based on market as of this date |
| March 1 | Homestead deduction filing deadline | File if you have not already |
| March-April | Assessment notices (Form 11) mailed | Review immediately |
| May 10 | Spring tax installment due | Pay |
| June 15 | Informal conference request deadline | Request if overassessed |
| 45 days after informal decision | Formal appeal deadline (PTABOA) | File if informal did not resolve |
| November 10 | Fall tax installment due | Pay |
Deadlines in property tax are not flexible. Miss the filing window by even one day and you lose your right to appeal for the entire year. That is another 12 months of overpaying with no recourse. As soon as you receive your assessment notice, find the deadline and mark it on your calendar with a reminder set for two weeks before.
If your deadline has already passed, check whether your state has a secondary appeal window. Some states allow filing with a higher court or board after the initial deadline. If no secondary option exists, start preparing now for next year's appeal so you are ready the moment your next notice arrives.
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).
Understanding this topic fully means looking at both the big picture and the specific details that apply to your situation. Every property is different, and the strategies that save the most money are the ones tailored to your particular home, location, and circumstances.
Start by gathering the basic facts about your property: its assessed value, the tax rate in your jurisdiction, and any exemptions currently applied. Then compare your situation to what is available. You may find opportunities for savings that you did not know existed.
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).
The appeal process is designed to be accessible to regular homeowners, not just attorneys and tax professionals. You do not need to hire anyone to file. The key is preparation. Gather your evidence before the hearing, organize it clearly, and practice presenting your case in under 10 minutes. Lead with comparable sales, then cover any property record errors, and finish with photos or documentation of condition issues.
Keep your tone professional and factual. Review boards respond to evidence, not complaints. If you walk in with 3 strong comparable sales and a calm, organized presentation, you are already ahead of most appellants.
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.
Do not assume you are automatically enrolled. Most exemptions require an application, and many homeowners lose years of savings simply because they never filed. Contact your county assessor's office or check their website for the application form. Bring proof of eligibility (age verification, disability documentation, veteran status, etc.) and file well before the deadline.
If you qualify for multiple exemptions, apply for all of them. In most jurisdictions, exemptions stack. A senior homeowner who is also a veteran can often claim both exemptions simultaneously, doubling the savings.
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.

Your Next Steps
Here is what to do right now:
- Check your state's deadline. Use the tables above to find your state's specific dates. If your deadline is within the next 60 days, start preparing immediately.
- Open your assessment notice. If you received one recently, read it today. Do not set it aside. Check the assessed value, property details, and the appeal deadline printed on it.
- Gather comparable sales. If your assessed value looks too high, pull 3 to 5 recent sales of similar homes in your area. This is the single most important piece of evidence for any appeal.
- File for exemptions you have not claimed. Many homeowners miss exemptions simply because they never applied. Check what is available in your state and file before the deadline passes.

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.
