If you own the home you live in in Indiana, the homestead exemption, officially the homestead deduction, is one of the biggest property-tax breaks available to you, and thanks to a major 2025 reform law, the rules are changing for the 2026 tax year. Here’s a plain-English guide to how the Indiana homestead exemption works, what you’ll save, who qualifies, and how to make sure you’re actually getting it.
Quick note on wording: Hoosiers usually say “homestead exemption,” but in Indiana the benefit is technically called the homestead deduction. Same thing, a reduction in the taxable value of your primary home. We’ll use both terms below.
What the Indiana homestead exemption actually is
Your property-tax bill starts with your home’s assessed value. The homestead deduction lowers the portion of that value the county can actually tax. Indiana gives qualifying homeowners two stacked deductions:
- Standard homestead deduction: reduces your home’s taxable assessed value by $48,000 for the 2025 assessment year (reflected in property taxes payable in 2026) and by $40,000 for the 2026 assessment year (reflected in taxes payable in 2027).
- Supplemental homestead deduction: subtracts a percentage of whatever value is left after the standard deduction. For 2026, that percentage rises to 40% (up from 37.5%).
These deductions reduce your home’s taxable assessed value. They are not dollar-for-dollar savings on your tax bill. What you actually save depends on your local tax rate.
Together, these can cut the taxable value of a typical owner-occupied home by roughly half.
A worked example (a $300,000 Central Indiana home, taxes payable in 2026)
| Step | Amount |
|---|---|
| Assessed value | $300,000 |
| Minus standard deduction | -$48,000 |
| Remaining value | $252,000 |
| Minus supplemental deduction (40% of $252,000) | -$100,800 |
| Taxable assessed value | $151,200 |
The deductions take this home from $300,000 down to about $151,200 of taxable value, roughly a 50% reduction before your local tax rate is even applied. On a home like this you’re often talking about thousands of dollars a year in savings.
What’s new for 2026: the SEA-1 reform
In 2025 Indiana passed Senate Enrolled Act 1 (SEA-1), the biggest property-tax overhaul since 2008. It phases in over six years (2026-2031). The headline changes that show up on your 2026 bill:
- A brand-new homestead credit. You get a credit equal to 10% of your property-tax bill, capped at $300. A credit comes off the bill after the tax rate is applied, so it’s a direct dollar-for-dollar reduction. Best part: it’s automatic, you don’t have to apply for it.
- A bigger supplemental deduction: up to 40% for 2026.
Looking further ahead, the standard deduction begins shrinking with the 2026 assessment year (from $48,000 to $40,000, reflected in taxes payable in 2027) and continues phasing down to $0 for the 2030 assessment year, while the supplemental deduction keeps rising to help offset it. Translation: the mix of how you get the break is changing. The takeaway for 2026 is simple, file for your homestead deduction and you’ll also pick up the new $300 credit automatically.
Who qualifies for the Indiana homestead exemption
You qualify if:
- You own the property (or are buying it under a recorded contract), and
- It’s your principal place of residence, the home you actually live in, not a rental or second home.
You can only claim the homestead deduction on one property, and a married couple can only claim one between them. Rentals, vacation homes, and investment properties don’t qualify (though SEA-1 does add a separate new deduction for rental housing and farmland starting in 2026).
How to file for your homestead deduction
This is the step people miss, especially new homebuyers. The deduction is not automatic when you buy a house. You have to file for it once:
- File the homestead deduction form (State Form HC10) with your county auditor. Many Central Indiana counties let you file online or at closing.
- Provide the last five digits of your Social Security and driver’s-license numbers (required to prevent people from claiming the deduction on more than one home).
- Once it’s approved, the deduction renews automatically every year, you don’t have to refile unless you move or your eligibility changes.
Filing deadlines shift, so confirm the current cutoff with your county auditor, but the safe move is to file as soon as you close on your home so you don’t miss a tax year.
A personal note from Greg: More than 30 years ago I bought my first home by assuming an FHA mortgage. A few years later I started my career in the mortgage industry. After I had been doing this a few years, I was telling people how important it is to check their homestead exemption, and I thought I had better check my own. That is when I learned I had been overpaying my property taxes ever since I moved in. If it can happen to a loan officer, it can happen to anyone. Take five minutes and check.
Central Indiana county auditor resources
- Marion County (Indianapolis): apply through the City-County / indy.gov homestead deduction page.
- Hamilton County (Carmel, Fishers, Noblesville, Westfield): apply through the Hamilton County Auditor’s office.
- Boone County (Zionsville), Hendricks, Johnson, and Hancock counties have their own auditor portals.
- Shelby County (Shelbyville): apply through the Shelby County Auditor’s office.
Why this matters when you buy a home
Here’s where it hits your wallet directly. Your mortgage payment usually includes an escrow portion for property taxes. If you buy a home and forget to file the homestead deduction, your assessed taxes can come in far higher than they should, which can cause an escrow shortage and a payment jump a year later. Filing the deduction promptly keeps your taxes (and your monthly payment) accurate from the start.
When you’re getting pre-approved, this is exactly the kind of detail a local broker catches that an out-of-state call center won’t. Estimating your real, post-deduction property taxes means a more accurate monthly payment and a smoother closing.
How the deduction shows up in your monthly payment
Property taxes are paid out of your escrow account, so every dollar of tax savings is spread across 12 monthly payments. The math is simple: every $1,000 a year in property-tax savings is about $83 less per month in your escrow payment. The new 2026 homestead credit (10% of your tax bill, capped at $300 a year) works out to up to about $25 a month, and it is applied automatically.
The flip side matters just as much. If the deduction is missing, your escrow can be set too high at closing, or you can get hit with a shortage and a payment increase later. If you are buying in Hamilton, Marion, or Shelby County, ask your lender to estimate taxes with the deduction in place, and file your HC10 soon after you close.
Homestead Exemption by County in Central Indiana
The Indiana homestead deduction is a statewide program, so the deduction amounts are the same in every county. What differs is where you file (your county auditor) and your final tax bill, which depends on local tax rates and your home’s assessed value. Here is where Central Indiana homeowners file:
Marion County (Indianapolis)
Indianapolis homeowners file the homestead deduction through the Marion County Auditor and the City-County (indy.gov) property-tax deduction portal. Many buyers can file right at closing.
Hamilton County (Carmel, Fishers, Noblesville, Westfield)
Homeowners in Carmel, Fishers, Noblesville, and Westfield file through the Hamilton County Auditor’s office. Because Hamilton County has some of Indiana’s highest home values, the homestead and supplemental deductions are especially valuable here.
Boone County (Zionsville)
Zionsville and other Boone County homeowners file with the Boone County Auditor.
Hendricks, Johnson & Hancock Counties
Homeowners around Avon and Brownsburg (Hendricks), Greenwood and Franklin (Johnson), and Fortville and Greenfield (Hancock) file with their respective county auditors. The process and deduction are identical statewide.
No matter your county, the rule is the same: file once with your county auditor after you close, and the homestead deduction renews automatically every year.
Indiana Homestead Law: The Basics
Indiana’s homestead deduction is established in state law (Indiana Code Title 6, Article 1.1) and was significantly reshaped by Senate Enrolled Act 1 (SEA-1) in 2025. Under Indiana homestead law, the deduction applies only to your principal place of residence, the one home you actually live in. The key legal points:
- You may claim the homestead deduction on only one property, and a married couple may claim only one between them.
- You must own the property or be buying it under a recorded contract.
- Claiming a homestead on a property that is not your principal residence, or on more than one home, can trigger back taxes and penalties, which is why the state requires the last digits of your Social Security and driver’s-license numbers to prevent duplicate claims.
- SEA-1 phases the deduction structure over 2026 to 2031, but the core eligibility rules stay the same.
Other Indiana Property Tax Deductions & Exemptions
The homestead deduction is the biggest, but Indiana offers additional property-tax relief that stacks with your homestead benefit if you qualify:
- Over-65 relief: Qualifying seniors may claim an over-65 deduction and a circuit-breaker credit that caps annual property-tax increases (income and assessed-value limits apply).
- Disabled-veteran benefits: Indiana greatly expanded veteran relief in 2026 (HEA 1210), totally disabled veterans (100% rating) can receive a full property-tax exemption, while partially disabled veterans receive credits. These stack on top of standard homeowner benefits. (See our VA loans page too.)
- Blind-or-disabled and surviving-spouse deductions are also available to those who qualify.
Eligibility and amounts for these programs change, so confirm the current details with your county auditor or the Indiana Department of Veterans Affairs before filing. This article is general information, not tax advice.

Frequently asked questions
Is it called a homestead exemption or a homestead deduction in Indiana? Both terms refer to the same benefit. Officially Indiana calls it the homestead deduction (plus a new credit for 2026), but most people search for “homestead exemption.”
How much is the Indiana homestead deduction for 2026? Eligible Indiana homeowners receive a standard homestead deduction that reduces their home’s taxable assessed value. The deduction is $48,000 for the 2025 assessment year, reflected in property taxes payable in 2026, and $40,000 for the 2026 assessment year, reflected in taxes payable in 2027. A separate supplemental homestead deduction (40% of the remaining value for taxes payable in 2026) may further reduce taxable assessed value. These deductions are not dollar-for-dollar savings on your tax bill. For 2026 there is also a new automatic credit of 10% of your tax bill, capped at $300, which does come directly off the bill.
Do I have to apply for the homestead exemption in Indiana? Yes, you must file the homestead deduction (Form HC10) with your county auditor one time. It then renews automatically. The new 2026 10% credit, however, is applied automatically without an application.
When should a new homebuyer file for the homestead deduction? As soon as you close. It’s not automatic with the purchase, and filing promptly ensures your property taxes, and your escrowed mortgage payment, are calculated correctly.
Does the homestead exemption apply to rental or investment property? No. It only applies to your primary residence. SEA-1 does introduce a separate new deduction for rental housing and farmland beginning in 2026.
Do I need to re-file if I move my home into a trust or change my deed? It is worth checking. Your county auditor’s records follow the owner of record, so after a deed change, a name added or removed, or a transfer into a trust, ask your auditor whether a new HC10 is needed. Do not assume the deduction carries over on its own.
