There is a specific kind of expensive mistake that new homeowners in Marion County make, and it happens quietly. They close in March or October, get their keys, start unpacking. Somewhere in that inch-thick closing packet, they assume someone handled the property tax exemption. Nobody did. The homestead exemption in Indiana is not automatic. It doesn’t transfer from the prior owner. The title company won’t file it. The deadline to capture it for the 2026 assessment year is January 5, 2027 — and for a lot of buyers, the holiday season is exactly when that date disappears into the noise.
This piece gives you the actual math, the actual steps, and the specific things that trip people up in Marion County. No one should lose $1,000 a year because they didn’t know to ask.
How Much the Exemption Actually Saves You
The Indiana homestead exemption works in two layers. Together they reduce the assessed value on which your property tax bill is calculated — not the bill itself, but the taxable base. That distinction matters when you want to understand why the savings vary by township.
Here’s the calculation for a typical Marion County home. The Assessor’s office and the Indiana Department of Local Government Finance should confirm the current median assessed value for 2026; this example uses $225,000, which reflects the approximate figure for a median single-family home in Marion County in recent years. Verify before publication.
Standard Deduction (IC 6-1.1-12-37)
The standard deduction is the lesser of 60 percent of assessed value or $45,000. For a $225,000 home, 60 percent gets you to $135,000 — well above the cap. So the deduction is a flat $45,000, leaving a remaining assessed value of $180,000. For any Marion County home assessed above $75,000, which is essentially all of them, this deduction is always $45,000. That part’s simple.
Supplemental Deduction (IC 6-1.1-12-37.5)
This is the one most new owners don’t know exists, and it actually delivers more total relief than the standard deduction for a median-priced home. It applies to whatever remains after the standard deduction, at 35 percent of that remaining value, on up to $600,000 of remainder. Confirm the current tier structure with DLGF.
For our example: 35 percent of $180,000 is $63,000. Net assessed value drops to $117,000.
A home assessed at $225,000 ends up taxed on $117,000 after both deductions — a reduction of $108,000 in taxable base.
What That Means on Your Tax Bill
Your actual dollar savings depend on your township’s tax rate, and the differences are real. Center Township, which covers much of Indianapolis’s urban core, carries a higher consolidated rate than Perry Township on the south side or Washington Township on the north. Marion County effective rates run roughly 1.0 to 1.3 percent depending on township. Confirm current certified rates with the Assessor’s office or the DLGF rate database before publishing specific figures.
At those rates, a $108,000 reduction in taxable base produces annual savings somewhere between $1,080 and $1,400 for this example. For a median-assessed home, accounting for where you land in the township rate range, realistic savings run from around $600 to over $1,000 per year. Over ten years of ownership, the unfiled exemption costs somewhere between $6,000 and $10,000. That is not an abstraction.
One more thing worth understanding: Marion County homestead properties are subject to Indiana’s circuit breaker cap, which limits property taxes to 1 percent of gross assessed value. Owners of lower-value homes may already be hitting that cap, which reduces the marginal benefit of the exemption. For most Marion County homeowners above the threshold, the full deduction delivers real savings.

The One Mistake New Buyers Make
Here is what the Marion County Assessor’s office hears constantly: “I thought my title company took care of it.”
They almost certainly didn’t. Indiana law places no obligation on title companies to file the homestead exemption on your behalf. Some include exemption forms in the closing packet as a courtesy — a pamphlet, a pre-filled cover sheet. Submitting that form is entirely your responsibility. No legal mechanism triggers automatic filing at closing. No county system detects a new owner and opens an exemption application.
The Assessor’s office receives frequent calls from new buyers who arrive shocked by a higher-than-expected tax bill, only to discover that no exemption was ever on file. Staff describe this as one of the most common calls they field in late spring, after May tax bills arrive. Whether buyer notification has improved in recent years is worth asking the Assessor — but don’t count on it having improved enough to protect you.
If you closed on a Marion County home in 2026 and haven’t independently filed the homestead exemption, assume it is not on file. Pull up the Assessor’s property search portal, which shows current exemption status by parcel. Then file.
The Exemption Does Not Transfer from the Prior Owner
When you browse your home’s listing on Zillow or look at old tax documents from closing, you may see “homestead exemption” listed. That exemption belonged to the prior owner. When the property sold, it expired. You must file independently, from scratch, as if the exemption never existed on that parcel.
The Marion County Assessor’s system is supposed to catch this at reassessment — when a sale is recorded, the exemption should be flagged for removal. In practice the notification process is inconsistent. Some buyers go months without any direct communication from the Assessor’s office telling them they need to file. The first sign that something went wrong is often a May tax bill that’s significantly higher than what the listing or closing documents suggested. By then, the January 5 deadline has already passed.
If your closing documents or your real estate agent told you the home “already has the homestead exemption,” that’s technically accurate for the seller’s final tax year. It is not true for you. If you’re weighing the full financial picture of buying versus staying put, what the rental market in Indianapolis is actually doing in 2026 is worth reading alongside the ownership costs this exemption affects.
The January 5, 2027 Deadline and What Happens If You Miss It
File by January 5, 2027, and the exemption appears on your May 10, 2027 spring installment. Full annual savings apply. Miss it and you lose the exemption for the entire 2026 assessment year — Indiana provides no grace period and no voluntary retroactive filing for missed years. You can file starting January 6 for the following year, but the missed year’s savings are gone. For a median-assessed Marion County home, that’s $600 to $1,000 you cannot recover.
The timing creates a specific hazard that doesn’t get enough attention. January 5 falls in the first week of the new year, which means the filing window runs directly through the holiday period. The Assessor’s office may operate on a reduced schedule between Christmas and New Year’s Day — confirm any adjusted hours before this article goes live. The safest approach: treat December 20 as your real deadline. File before the holidays start. The online portal accepts filings outside business hours, which is a genuine advantage. If you need to file in person or run into a problem with your online application, waiting until the last week of December is a gamble that has cost people a year’s worth of savings. Don’t make that bet.
How to Apply Online
The Marion County Assessor’s office processes homestead exemption applications through an online portal. The current URL must be confirmed with the Assessor’s office (317-327-4907) before publication. Confirm whether 2026 assessment year filings route through the Marion County Assessor’s own portal or through the state DLGF gateway — this has changed in some Indiana counties recently.
Start by finding your parcel number. It’s on your most recent property tax statement. No statement yet? Use the Marion County Assessor’s property search tool, search by address, and the parcel number appears in the property record. While you’re there, check whether any exemption is currently listed for your parcel. If the prior owner’s homestead exemption has already been removed, you’ll see nothing. Don’t assume you’re covered if the record hasn’t been updated. File anyway.
You’ll need your Indiana driver’s license or state ID — showing your current address matching the property address — plus your Social Security number and your spouse’s if the property is jointly owned. The address match on your license is a hard requirement, not a technicality. If you relocated from out of state and your license still shows a prior address, update your Indiana license first. The BMV has multiple Marion County locations. Get that handled, then file the exemption. Don’t let a license update be the thing that costs you a year of savings.
The portal walks you through parcel number, identification, and a certification that the property is your primary residence. It’s designed to be completed in a single session. Save your confirmation number or email when the application submits. A few weeks after filing, check the Assessor’s property search again to confirm the exemption appears on your parcel record. If it doesn’t, call the Assessor’s office to confirm receipt.
How to Apply In Person
For homeowners who want a paper trail, can’t complete the online process, or have a complicated situation — trust ownership, a recent name change, an address discrepancy — the in-person option is available.
Marion County Assessor’s Office
City-County Building
200 E. Washington St., Indianapolis, IN 46204
Confirm current weekday hours with the Assessor before publication. Standard hours are typically 8 a.m. to 4:30 p.m. weekdays, but confirm any variation, extended December hours, or holiday closures. Also confirm whether the Assessor accepts filings at any satellite locations — since the 2009 consolidation eliminated functioning township assessor offices for this purpose, the City-County Building is the primary location, but verify.
Metered street parking is available on Washington Street. The City Market parking garage is the closest structure, about a block and a half away.
Bring your Indiana driver’s license or state ID showing the property address, your parcel number, and your Social Security number (and your spouse’s, if applicable). If the property is held in trust, bring documentation showing the trust beneficiary occupies the home as their primary residence — confirm the current Marion County requirement with the Assessor’s office, as the documentation package can vary. Ask the counter staff for a stamped copy of your filing before you leave. Don’t walk out without it.
Edge Cases That Standard Guidance Ignores
Mid-Year Closings
If you purchased after March 1, 2026, the prior owner’s homestead exemption covers the taxes owed for the 2026 pay year. Your spring and fall 2026 bills are calculated using the prior owner’s exemption status. Your job is to file by January 5, 2027 for the 2026 assessment year going forward. Confirm with the Assessor whether any transitional provisions apply specifically to closings in the final quarter of 2026 — October, November, and December buyers are also the ones most likely to be distracted by a new house during the filing window.
New-construction buyers in fast-growing areas of northeast Marion County and in Decatur Township should pay particular attention. Builders and lenders do not file homestead exemptions. First-year assessed values on new construction can run significantly higher than the purchase price might suggest. File regardless of whether your first tax bill has arrived.
Properties Held in Trust
If your home is owned by a revocable living trust, you can still qualify for the homestead exemption, but additional documentation is required to show that the trust beneficiary occupies the home as their primary residence. Contact the Marion County Assessor’s office for the current documentation package. Don’t assume the standard online application covers a trust-owned property without checking first.
Rental and Investor-Owned Properties
The homestead exemption is for owner-occupants only — people who own the property and live in it as their primary residence. It doesn’t apply to rentals, short-term rentals, Airbnb units, or properties owned by LLCs or investors who don’t personally reside there. Marion County’s active investor market makes this a recurring problem. Properties purchased by investors or converted to rentals sometimes carry a homestead exemption from a prior owner-occupant’s filing that should have been removed. If you’re a landlord reviewing your portfolio, check that no exemption you didn’t legitimately qualify for is attached to your parcels. The Assessor’s office audits for this.
If You Already Missed a Year
If you bought in 2024 or 2025 and you’re reading this with the sinking realization that you never filed, your options are limited but not zero. Indiana generally doesn’t allow voluntary retroactive filings for missed exemption years. If you simply didn’t file in time, that year’s savings are gone.
There is one exception worth knowing. If the exemption was incorrectly denied or never processed due to an administrative error — not a missed deadline on your part, but a failure in the Assessor’s processing — limited corrective action may be available. That distinction is meaningful. It’s worth a direct call to the Assessor’s office if you believe the error was on their end, not yours. Confirm the exact policy and the documentation burden with the Assessor directly; their answer should be quoted or summarized in this piece.
File now for the current year, accept that prior missed years are most likely unrecoverable through normal channels, and treat January 5 as a date that does not move.
