Hamilton County Homestead Exemption
Last Updated: August 2026
If you own and live in your Hamilton County home as your primary residence, the Indiana Homestead Standard Deduction can significantly reduce the assessed value used to calculate your property taxes.
Although homeowners often call it the Homestead Exemption, Indiana officially calls it the Homestead Standard Deduction. Hamilton County homeowners apply through the Hamilton County Auditor’s Office.
Quick Answer
If your Hamilton County property is your primary residence and you have a qualifying ownership interest, you may be eligible for the Homestead Standard Deduction.
You can apply online through Hamilton County’s official property tax deduction system:
Apply for the Hamilton County Homestead Deduction
For a person applying in 2026 for property taxes first due and payable in 2027, Hamilton County says the application must be filed by January 15, 2027.
Once approved, you generally don’t have to apply again unless something changes, such as your deed, marital status or use of the property.
Who Qualifies for the Homestead Deduction?
The Homestead Standard Deduction is a residency-based property tax benefit.
Generally, the property must be:
- Located in Indiana
- Your principal place of residence
- Occupied by you
- Owned by you or held through another qualifying ownership arrangement
Individuals and married couples are generally limited to one Homestead Standard Deduction on their primary residence.
This means you generally can’t claim a Hamilton County home as your homestead while also receiving a homestead benefit on another primary residence.
If you’re unsure whether your ownership arrangement qualifies, contact the Hamilton County Auditor’s Real Property Department before filing.
How Much Is the Hamilton County Homestead Deduction?
Indiana is gradually changing the Standard and Supplemental Homestead deductions.
For 2025 pay 2026, Hamilton County lists:
Standard Homestead Deduction: $48,000
Supplemental Deduction: 40%
For 2026 pay 2027, the amounts change to:
Standard Homestead Deduction: $40,000
Supplemental Deduction: 46%
The Standard Homestead Deduction is scheduled to decrease over several years while the Supplemental Homestead Deduction percentage increases.
You do not need to file a separate application for the Supplemental Homestead Deduction. If you qualify for the Standard Homestead Deduction, the supplemental deduction is automatically calculated.
Check Hamilton County’s Standard Homestead information for the current year’s amounts.
New Supplemental Homestead Credit
Indiana has also added a Supplemental Homestead Credit.
This is separate from the Supplemental Homestead Deduction.
For qualifying homeowners, the credit equals 10% of the property tax liability attributable to the homestead, up to a maximum of $300 per year.
For example:
If the qualifying tax liability is $2,000, the credit would be $200.
If the qualifying tax liability is $4,000, the credit would reach the $300 maximum.
You do not need to file a separate application for this credit. Hamilton County says it is automatically applied to qualifying parcels that receive the Standard Homestead Deduction.
How to Apply Online
Hamilton County allows homeowners to file the Homestead application online.
Start with:
Hamilton County Property Tax Deduction Forms
Select Claim for Homestead Property.
Hamilton County’s system allows you to locate your property and complete the Homestead claim electronically.
You will need information about yourself and the property. Hamilton County says applicants are required to provide information including:
- Social Security number
- Driver’s license number
- Spouse’s Social Security number, when applicable
- Spouse’s driver’s license information, when applicable
The spouse information requirement can apply regardless of how title to the property was taken.
When Should I Apply?
Don’t wait until you receive a tax bill and discover the Homestead Deduction is missing.
Hamilton County says a person applying in 2026 for property taxes first due and payable in 2027 must apply by:
January 15, 2027
Because filing requirements and deadlines can change, check the Hamilton County Property Tax Deductions & Credits page for the deadline that applies when you’re filing.
Do I Have to Reapply Every Year?
Usually, no.
Once your Homestead Deduction has been approved, Hamilton County says you generally don’t have to reapply unless there has been a change involving:
- Your deed
- Your marital status
- The use of the property
If you’ve recently bought your home, changed ownership or changed your marital status, it’s worth checking your Homestead status rather than assuming the deduction continued automatically.
How to Check Whether You Already Have the Homestead Deduction
Hamilton County makes this fairly easy.
Use the official Hamilton County Property Reports & Payments system.
Find your property and look under Current Deductions and Credits.
The county’s system shows the deductions and credits currently associated with the property and the applicable owner and year.
→ View Tax Lookup
This is especially useful if you’ve owned your home for several years and can’t remember whether you ever filed.
I Just Bought a House — What Should I Do?
If you recently purchased a Hamilton County home that will be your primary residence, check the Homestead Deduction soon after closing.
Don’t assume that because the previous owner had a Homestead Deduction, you’ll automatically receive it.
Hamilton County’s online deduction system specifically instructs homeowners to file when they:
- Purchase the property
- Make changes to the deed
- Have a change in marital status
You can start the process through Hamilton County’s Online Deduction Forms.
What If I Move?
A Homestead Deduction is tied to your qualifying primary residence.
If a property becomes ineligible — for example, because you move and it is no longer your primary residence — you are responsible for notifying the Hamilton County Auditor.
Hamilton County says homeowners must provide a certified statement to the Auditor within 60 days of the change when the property becomes ineligible.
The county provides an Ineligible Homestead Certification through its online deduction system.

Failing to report an ineligible Homestead Deduction can result in back taxes and penalties.
Homestead Fraud and Eligibility Reviews
Hamilton County actively reviews Homestead Deduction eligibility.
The Hamilton County Auditor has partnered with Tax Management Associates (TMA) to help identify potentially ineligible Homestead claims.
Hamilton County advises that some residents may receive a letter from TMA asking for additional information to verify their eligibility.
If you receive one of these letters, don’t automatically assume it’s junk mail or a scam. Hamilton County specifically states that these letters are part of its Homestead verification program.
You should respond as requested or contact the Hamilton County Auditor if you have questions.
Homestead Deduction vs. Property Assessment
The Homestead Deduction doesn’t change the actual market value the Assessor assigns to your property.
For example, your home may have an assessed value of $350,000. The Homestead and other applicable deductions are then considered as part of the property tax calculation.
If you think the assessed value itself is incorrect, that’s a separate issue.

If the assessment looks correct but your Homestead Deduction is missing, contact the Auditor, not the Assessor.
Other Property Tax Deductions and Credits
The Homestead benefit isn’t the only property tax relief available to Hamilton County residents.
Depending on your circumstances, you may also qualify for benefits related to:
- Age
- Disability or blindness
- Veteran status
- Other qualifying situations
Indiana changed several of these benefits beginning with newer tax years, including converting the former Over-65 and Blind/Disabled deductions into credits.
