How Assessment Works in Indiana

Indiana assesses property at 100% of market value-in-use, using a "trending" methodology that adjusts values based on local sales data. Your assessed value should reflect what your home would sell for, adjusted for the assessment date.

Risk of Increase

In Indiana, filing a appeal can result in your assessed value being increased. This is uncommon when you have strong evidence of over-assessment, but you should be aware of this possibility. ProtestMax only recommends filing when our analysis shows a clear case for reduction.

FAQ

Indiana Property Tax Appeal Questions

What is "trending" in Indiana assessments?

Trending is Indiana's method of adjusting assessed values annually based on local sales data. The county assessor applies a factor to property values in each neighborhood to keep assessments in line with market conditions.

Can my Indiana assessment increase on appeal?

Yes. The PTABOA or Board of Tax Review can increase your assessment. However, this is uncommon when you present strong comparable sales evidence showing over-assessment.

What is Form 130?

Form 130 is Indiana's official Petition for Review of Assessment. It is the form you file with the county assessor to initiate a property tax appeal. ProtestMax generates this form pre-filled with your property details.
