If you own and live in your Indianapolis home and have never filed for the homestead deduction, you are probably overpaying your property tax bill by several hundred dollars a year. The gap has grown wider as Marion County assessed values climbed sharply after 2020. This piece covers what the deduction is, what it actually saves in dollar terms at realistic Marion County price points, who qualifies, who doesn’t, and how to file before the January deadline.
Same goes if you bought your house in the last year or two and assumed the exemption carried over from the previous owner. It didn’t. More on that shortly — and yes, this is one of those things your title company probably didn’t mention at closing, because they almost never do.
What Is the Indiana Homestead Exemption?
The homestead exemption reduces the assessed value on which your property tax bill is calculated. It’s formally a deduction under Indiana law, not a tax credit — not a flat rebate, not a percentage knocked off your final bill. It lowers the number the county multiplies your tax rate against. The higher your assessed value, the more dollars the deduction saves you in absolute terms.
There are actually two pieces: the standard deduction and the supplemental deduction. Most coverage either ignores the supplemental piece or buries it in a footnote. That’s a mistake that costs homeowners real money.
The standard deduction is the larger of the two and comes off your gross assessed value first. The supplemental deduction then applies to the net assessed value remaining after the standard deduction is subtracted. Together they determine your final taxable assessed value — the number your Marion County property tax rate actually gets applied to.
Both deductions appear on your annual tax statement and on the property record in the Marion County Assessor’s database. If you don’t see both line items on your record, call to confirm your status.
How Much Will the Exemption Actually Save Me?
Indiana’s standard homestead deduction is calculated as the lesser of 60 percent of your home’s gross assessed value or a statutory cap of $45,000. Verify the current cap with the Marion County Assessor or DLGF before relying on this figure — the legislature has adjusted it before. The supplemental deduction is 35 percent of the net assessed value remaining after the standard deduction comes off.
A $200,000 Home in Irvington or Meridian-Kessler
Gross assessed value: $200,000. The standard deduction would be 60 percent, or $120,000, but it caps at $45,000. Net assessed value: $155,000. The supplemental deduction is 35 percent of that — $54,250. Your final taxable assessed value is $100,750.
Marion County’s effective property tax rate varies by township and by the stack of overlapping taxing units: school district, municipality, library district. County data places the average effective rate across much of Marion County somewhere around 0.85 to 1.0 percent. Verify the rate for your specific township with the Marion County Treasurer — these numbers move.
At a midpoint estimate of 0.925 percent, a $200,000 home without the exemption runs roughly $1,850 a year in property tax. With the exemption, about $932. That’s somewhere around $900 in annual savings. Not a rounding error at any income level. And as assessed values climb — Marion County values have risen substantially in Washington Township, Broad Ripple, and Lawrence since 2020, a trend documented in our Marion County housing market coverage — the dollar value of the exemption grows with them, because the supplemental percentage applies to a larger base.
Worth noting: if you filed for only the standard deduction and missed the supplemental piece, you’re leaving roughly $150 to $200 a year unclaimed. That’s a smaller number but still an entirely avoidable one.
A $130,000 Home in Warren Township or Beech Grove
Gross assessed value: $130,000. The standard deduction would be 60 percent, or $78,000, but again caps at $45,000. Net assessed value: $85,000. The supplemental deduction is 35 percent of that — $29,750. Taxable assessed value: $55,250.
At the same 0.925 percent effective rate, you’re paying roughly $1,203 a year without the exemption and about $511 with it. Savings in the range of $650 to $700 annually — significant at that end of the market, where property tax bills represent a larger share of household income. If your assessed value seems wrong and is costing you more than it should, the process for appealing your Marion County property tax assessment is a separate step worth understanding alongside the exemption filing.
Who Qualifies, and What Knocks You Off the List?
You must own the property and occupy it as your principal place of residence as of March 1 of the assessment year. Indiana code is not ambiguous on this. You live there. It is your primary home.
Rental and investment properties don’t qualify. No exceptions based on assessed value or length of ownership.
The house-hacking scenario — owning a duplex and living in one unit while renting the other — is more complicated. The owner-occupied unit may qualify for the homestead deduction on the portion of assessed value attributable to that unit; the rental unit doesn’t. The Assessor’s office handles these case by case, and the outcome depends on how the property is assessed. If this is your situation, call the Assessor directly rather than assuming either way. The dollar consequences of getting it wrong are real enough to warrant a phone call.
Indiana limits the homestead deduction to one property per qualifying owner. If you own two homes and occupy both at different points in the year, you must designate one as your primary residence. You cannot claim the deduction on both.
Trust-held properties are one of the most commonly misunderstood situations in Marion County estate planning. If your home is held in a revocable living trust — standard in estate planning — the deduction is still available, but only if the beneficiary of the trust occupies the property as their primary residence. Ownership through a trust doesn’t disqualify you. But the residency requirement follows the beneficiary, not the trust instrument. If you recently transferred your home into a trust, confirm with the Assessor that your exemption filing reflects the current ownership structure.
Manufactured homes in Marion County that are taxed as real property rather than personal property — meaning they’re on a permanent foundation and assessed as real estate — may also be eligible. Ask the Assessor’s office directly.
I Just Bought My Home. Do I Need to Refile?
Yes. This is the most important thing in this article for new buyers.
The homestead deduction does not transfer with the deed in Indiana. When you purchase a home, the previous owner’s exemption terminates. You’re a new owner, and the Assessor requires a fresh application before the deduction can be applied to your bill.
The Assessor is supposed to send new owners a notice when a property changes hands. In practice, don’t wait for it. The notice doesn’t always arrive promptly, and if January 5 passes before you file — regardless of whether you ever received anything — you lose the deduction for that tax year. No exceptions.
This problem shows up most clearly in Marion County’s highest-turnover neighborhoods. Broad Ripple, Fountain Square, Meridian-Kessler, Irvington, and Lawrence all see heavy resale volume. Each sale creates another buyer who may not know to refile. Real estate attorneys and title companies don’t consistently flag this at the closing table. It’s a straightforward thing to mention and it almost never gets mentioned.
If you bought your home after January 1 of last year and haven’t filed a homestead application, check your property record now at the Marion County Assessor’s property search portal. If the exemption doesn’t appear on your record under your name, file immediately.
Newly constructed homes follow the same rule. Your first assessment doesn’t automatically include the homestead deduction. File after taking ownership and establishing primary residency.
What Is the Filing Deadline, and What Happens If I Miss It?
Indiana statute sets the homestead deduction filing deadline at January 5 of the year in which the deduction is to apply. For the 2026 tax year, your application must be on file with the Marion County Assessor by January 5, 2026. Confirm the exact date with the Assessor’s office — when January 5 falls on a weekend or holiday, the effective deadline may shift.
If you’re reading this in the fall, you have time. Reading this in February after the deadline has passed? You’ve missed the deduction for 2026 and will file for 2027 instead. Frustrating, but nothing about the Indiana homestead statute is retroactive.
Missing the deadline carries no late fee or penalty. The only consequence is financial: no deduction for the missed year, no retroactive credit. The exemption applies from the first year you successfully file — which is why filing promptly after purchase is the only way to avoid losing money in year one.
How Do I File?
Marion County consolidated its assessment functions years ago, and I still hear people get tripped up on this. The township assessor structure is gone. Searching “Pike Township assessor” or “Warren Township assessor” will turn up references to an office that no longer exists. All homestead exemption filings in Marion County go through the Marion County Assessor’s office, located in the City-County Building at 200 E. Washington St. in downtown Indianapolis. Verify the current suite number, phone number, and hours before visiting.
The online portal at assessor.indy.gov accepts applications directly. It’s the fastest option. Verify that the URL is active and that the portal is currently accepting homestead applications before using it. The system generates a confirmation you can save.
You can also download Form HC10 — the Indiana Homestead Deduction Application — from the Indiana Department of Local Government Finance or pick one up at the Assessor’s office. Mail it to the address on the form or drop it off in person. Verify the current mailing address before sending anything.
For complex situations involving trusts, multi-unit properties, or anything where you’re genuinely unsure of your eligibility, go in person. Staff can walk you through the application and confirm your filing on the spot. Bring something that shows you own the property and that it’s your primary address — a driver’s license with the property address and your most recent mortgage statement or deed are typically sufficient. Confirm what documentation the Assessor currently requires before your visit.
Phone: (317) 327-4907. Treat this as unconfirmed and verify before calling.
How Do I Confirm the Exemption Is Already on My Record?
If you’ve owned your home for a few years and aren’t sure whether you ever filed — or whether a past filing is still active — you can check in about two minutes.
Go to the Marion County Assessor’s property search tool at assessor.indy.gov and look up your address. The assessment record should display the deductions currently applied to your property. You’re looking for two separate line items: the standard homestead deduction and the supplemental homestead deduction. Both there? You’re current. One or neither? Call the Assessor and find out what happened.
The Assessor doesn’t notify owners when an exemption lapses or was never filed. Ownership changes can cause the deduction to drop off the record without any alert to the new owner. Two minutes of checking could save a year’s worth of overpayment.
One scenario worth flagging specifically: a homeowner dies, the property passes to a family member who moves in, and that family member never refiles because they assumed the exemption was part of the property record. It isn’t. Every change in ownership — including inheritance — requires a new filing. The exemption belongs to the owner-occupant, not to the house. When that relationship changes, the clock resets.
