How to Appeal Your Property Taxes in Indiana

How to appeal your property taxes in Indiana

To appeal your property taxes in Indiana, file a written appeal with your county or township assessor after you receive your assessment notice (a Form 11 Notice of Assessment) or your tax bill, then support your case with evidence that your property's assessed value is higher than its true market value-in-use. Indiana law gives homeowners the right to challenge an assessment they believe is inaccurate, and the process moves from an informal review with the assessor to a formal hearing before the county Property Tax Assessment Board of Appeals (PTABOA) if you cannot reach agreement.

A property tax appeal in Indiana does not argue that your taxes are too high in the abstract. It argues that the assessed value the county placed on your home is wrong — usually too high compared to what the property would actually sell for. If you win, your assessed value is lowered, and your tax bill follows.

This guide explains the Indiana appeal process in general terms so you know what to expect. Because deadlines, forms, and local practices vary by county and can change, always confirm the specifics on your own assessment notice and your county assessor's website before you act.

Understand what you are appealing

Indiana assesses residential property based on its true tax value, which for most homes reflects market value-in-use — essentially what the property is worth in its current use. Your county or township assessor estimates this value, and it appears on:

• Your Form 11 (Notice of Assessment of Land and Structures), if one is mailed for the year, or
• Your annual property tax statement (tax bill).

The grounds for a successful appeal almost always come down to one idea: the assessed value is higher than the property's actual market value. Common, legitimate reasons include:

• Comparable homes nearby sold for less than your assessed value.
• The assessment lists incorrect facts — wrong square footage, wrong number of bathrooms, a finished basement that isn't finished, a garage that doesn't exist.
• Your home has condition problems (foundation, roof, water damage, needed repairs) that the assessment doesn't reflect.
• Your assessment jumped sharply without a corresponding change to the property.

Know your key date before anything else

Indiana sets a filing window for appeals, and it is typically tied to the date on your notice — for example, a set number of days after the Form 11 is mailed, or a deadline connected to when tax statements go out. Do not rely on a remembered date or a number from another county or another year. Read your own notice, or check your county assessor's page, and calendar the exact deadline. Missing the window is the most common reason appeals fail before they begin.

Step-by-step: how to file an Indiana property tax appeal

1. Read your assessment notice carefully. Find the assessed value, the property record details, and any stated appeal deadline or instructions.
2. Confirm your deadline. Verify the filing window on the notice itself or with your county/township assessor. Note it before doing anything else.
3. Pull your property record card. Request it from the assessor (many counties post it online). Check every fact: lot size, living area, year built, room counts, condition, and any features.
4. Gather evidence of value. Collect recent sales of comparable homes in your area, a recent appraisal if you have one, photos of defects or needed repairs, and repair estimates.
5. File the appeal in writing. Indiana appeals generally start with a written notice to the assessor. Many counties use a state appeal form (often referenced as Form 130); confirm the correct form and filing method — mail, in person, or online — with your county.
6. Request and attend the informal review. The assessor may offer an informal meeting to resolve the disagreement. Bring your evidence; many appeals are settled here.
7. Go to the PTABOA hearing if needed. If you and the assessor don't agree, your appeal goes to the county Property Tax Assessment Board of Appeals for a formal hearing. Present your comparables and documentation clearly.
8. Appeal further if warranted. If you disagree with the PTABOA decision, Indiana provides a next level of review through the Indiana Board of Tax Review, and beyond that the Indiana Tax Court. Each level has its own deadline — confirm it when you receive a decision.
9. Keep copies of everything. Save your filing, your evidence, and every notice and decision, with dates.

Build the strongest possible case

The homeowner carries the burden of showing the assessed value is wrong, so evidence wins appeals — not opinion.

The evidence that actually moves an assessment

• Comparable sales (comps): Recent arm's-length sales of similar homes near you are the most persuasive evidence. Match on location, size, age, style, and condition as closely as you can.
• A professional appraisal: An independent appraisal near the relevant valuation date can be strong support, though it has a cost.
• Errors on the property record card: Documented factual mistakes are often the easiest wins because they are objective.
• Condition and repair evidence: Dated photos and written repair estimates for real problems can justify a lower value.

Checklist before you file

• [ ] Located my assessed value and the property details on the notice
• [ ] Confirmed my exact filing deadline from my own notice or county assessor
• [ ] Reviewed my property record card for factual errors
• [ ] Gathered 3-5 strong comparable sales
• [ ] Collected photos, repair estimates, or an appraisal if applicable
• [ ] Identified the correct appeal form and filing method for my county
• [ ] Made copies of my complete appeal package
• [ ] Calendared the informal review and any hearing dates

What to expect after you file

Most Indiana appeals begin with an informal review, where many disagreements are resolved without a formal hearing. If yours proceeds to the PTABOA, you'll present your evidence at a scheduled hearing and receive a written determination. Timelines vary widely by county and by how busy the local board is, so patience helps. Continue paying your tax bill while the appeal is pending unless your county instructs otherwise — an appeal does not automatically pause what you owe, and a successful appeal is typically reconciled afterward.

Common mistakes to avoid

• Missing the deadline. Confirm it from your own notice; don't assume.
• Arguing the tax rate. You appeal the assessed value, not the millage or your total bill directly.
• Bringing opinions instead of evidence. "My taxes feel too high" is not a case; comparable sales are.
• Using weak comps. Homes in different neighborhoods, sizes, or condition tiers undercut your argument.
• Ignoring the record card. Factual errors are often the fastest path to a reduction.

Should you appeal?

Consider appealing if your assessed value looks higher than what your home would realistically sell for, if comparable homes are assessed or sold for noticeably less, or if the property record contains errors. The appeal itself is generally low-cost to start, and correcting an inflated assessment can lower your bill for the current year and set a more accurate baseline going forward. If your assessment already tracks market value, an appeal is unlikely to help.

When in doubt, start with the two free steps that cost you nothing but time: request your property record card and pull recent comparable sales. Those two documents tell you quickly whether you have a case worth filing.
