Indiana Property Tax Law Changes 2026: What Homeowners Need to Know

Updated March 2026

Key Takeaway

Indiana has the most aggressive constitutional property tax caps in the nation: 1% for homesteads, 2% for other residential, 3% for all other property. These caps are in the state constitution (since 2010) and cannot be exceeded regardless of local tax rates. Indiana also offers a generous $48,000 standard deduction and an over-65 deduction of up to $14,000.

Constitutional Property Tax Caps (1%/2%/3%)

Indiana's property tax caps are embedded in the state constitution (Article 10, Section 1), making them extremely durable:

1% cap: Homestead (owner-occupied primary residence)
2% cap: Other residential and agricultural land
3% cap: All other property (commercial, industrial, vacant)

This means your property taxes can never exceed 1% of your assessed value if it's your homestead. On a $200,000 home, your maximum tax bill is $2,000/year. Period. This is the strongest cap in the nation.

Standard Deduction (Homestead)

Indiana's standard homestead deduction is the lesser of 60% of assessed value or $48,000. For the median Indiana home ($148,600), this deduction removes $48,000 from your assessed value. Combined with the 1% cap, this is very powerful. You must file for homestead deduction -- it is not automatic.

Over-65 Deduction

Homeowners 65+ receive an additional deduction of up to $14,000 on assessed value, subject to income limits of approximately $40,000. This stacks on top of the standard deduction and works within the 1% cap framework.

Form 11: Your Assessment Notice

Indiana mails assessment notices on Form 11. You have 45 days from the postmark date to file an appeal. The Form 11 shows your assessed value, deductions applied, and estimated tax. Review all three carefully -- sometimes deductions are incorrectly removed or not applied at all.

Trending Factor

Indiana uses a "trending factor" to adjust assessed values between full reassessment years. The trending factor is a multiplier applied to your base assessment to approximate current market value. If the trending factor overshoots market conditions, this is a valid appeal argument. Check your county's trending factor on the Indiana Department of Local Government Finance website.
