Indiana Homestead Deductions 2026: Standard, Supplemental, and a New Credit

Updated August 2026

Indiana's homestead benefit is stacking deductions and credits, not a single flat exemption, and the Standard Deduction amount is scheduled to phase down each year through 2030. The old Mortgage Deduction was repealed and no longer exists.

Every Indiana owner-occupant qualifies for the Standard and Supplemental Homestead Deductions automatically once filed, no age or income test, plus a new Supplemental Homestead Credit and the existing 1% tax cap. Seniors and disabled homeowners can add smaller, separate income-tested credits on top.

Supplemental Homestead Deduction + Credit

An exemption or credit lowers your bill only after the assessed value is set. If that value is too high to begin with, you are overpaying on everything above it regardless of which relief programs you claim. Nobody checks the underlying value unless you do.

How to Apply

Contact your county assessor's (or, where noted above, your state revenue department's) office for the current application form
Gather proof of ownership, occupancy, and, for income-tested programs, your prior-year income documentation
File before the deadline listed above, most jurisdictions do not accept late applications for that tax year
Confirm the relief shows up on your next assessment notice or tax bill

The Bottom Line

The Standard Deduction is shrinking on a set legislative schedule through 2030, so don't rely on older figures you may have seen. File once with your county auditor and it carries over automatically unless you notify them of a change in eligibility.

Note: Program names, dollar figures, and income limits above are current as of August 2026 and are set or adjusted by the state legislature or department of revenue, not by AppealDesk. Some figures adjust annually, confirm the current-year number with your county or state before applying. AppealDesk helps homeowners identify available relief programs and appeal overassessments.

Most homeowners stack these programs on top of whatever value the assessor assigned and never question the value itself. It came from a mass-appraisal model, not an individual review of your home. It is worth checking once.
