Indiana's 2026 legislature transformed what veteran property tax relief is worth. We covered the substance of that change — the 100%-of-assessed-value deduction for totally disabled veterans, with no home-value cap, extended to surviving spouses — in our HEA 1210 breakdown, and we won't re-explain the law here. This post is about the part that actually determines whether the benefit lands on your bill: the filing mechanics in Marion County. Which benefits exist, which office takes the paperwork, what documents you need in hand, and the deadlines that separate a 2027 bill with relief from one without it.
The benefits on the table
Indiana's veteran property tax framework has two layers right now: the long-standing deductions, and the restructured benefits that first apply to 2026 assessments, payable in 2027.
| Benefit | Statute | What it is |
|---|---|---|
| Wartime service deduction | IC 6-1.1-12-13 | $24,960 off assessed value for wartime veterans with a 10%+ service-connected disability |
| Totally disabled / over-62 deduction | IC 6-1.1-12-14 | $14,000 off assessed value; historically limited by a $240,000 assessed-value cap |
| HEA 1210 total-disability deduction | New for pay-2027 | 100% of assessed value, no value cap, for totally disabled veterans; extends to non-remarrying surviving spouses |
| Restructured partial-disability credits | New for pay-2027 | Flat-dollar credits for veterans rated 10%–90% |
The prior-law amounts are documented in the DLGF's veterans deductions FAQ, and the $240,000 assessed-value cliff sits in IC 6-1.1-12-14 itself; the Indiana Department of Veterans Affairs now documents the restructured benefits. For the partial-disability side, Daily Journal coverage of county veteran service offices describes the new structure as a $350 credit for wartime veterans with at least a 10% service-connected disability and a $250 credit for veterans 62 or older with at least a 10% rating — stackable, for a maximum of $600.
Note
Your 2026 installments (paid May 11 and due November 10) were computed under the old rules. Everything you file in Marion County during 2026 is aimed at the bills payable in 2027 — the first cycle the new benefits apply to.
Where to file in Marion County
Veteran deductions are a county auditor filing, not an assessor filing. In Marion County that means:
| Channel | Details |
|---|---|
| Online | The indy.gov disabled veteran deduction page walks through the application, and the auditor's digital services let you apply for deductions and check what's already on your parcel |
| In person | Marion County Auditor's Office, City-County Building, 200 E. Washington St., Suite 841, Indianapolis |
| By phone (questions) | 317-327-4646 |
Before you file anything, pull your parcel and check which deductions are already on record — the auditor's site lets you search current deductions by address, and Property Lookup shows your assessment and deduction history side by side. A surprising number of veterans qualified under the old rules for years and never filed at all.
The documents you need
The application vehicle is State Form 12662 (Application for Tax Deduction for Disabled Veterans and Surviving Spouses), available from the DLGF's deduction forms page or the auditor's office. Per the Indiana DVA, bring:
- Your VA award or summary letter showing your combined disability percentage — and, for total-disability claims based on individual unemployability, the VA documentation establishing it. Request a fresh letter if yours is more than a year old.
- Your DD-214, Member 4 copy, showing character of discharge and service dates. Wartime-period service matters for the IC 6-1.1-12-13 benefit.
- Surviving spouses: the veteran's records above, plus your marriage certificate and the veteran's death certificate.
Marion County's Veteran Service Office can help you complete Form 12662 before you take it to the auditor — a worthwhile stop if your VA paperwork is incomplete.
The two deadlines that matter
December 30, 2026 — the registration window for the restructured benefits. Registration for the new credits opened July 1 and runs through December 30, 2026, filed with your county auditor on Form 12662 — county veteran service offices and auditors have been urging veterans to file. Critically, veterans already receiving the old deductions are being told to register under the new structure. Do not assume the county converts you automatically.
January 15 — the general deduction backstop. Under the DLGF's standing rule, deduction applications must be completed and filed with the county auditor on or before January 15 of the calendar year in which the taxes are first due. File in 2026 and the benefit reaches the 2026-assessment, pay-2027 bill.
Warning
Treat December 30, 2026 as your real deadline, not January 15. It is the registration cutoff county offices across the state are publicizing for the new credits, and filing early leaves time to fix a rejected document while the window is still open. A missed window means waiting a full billing cycle.
Stacking with homestead and over-65 benefits
Veteran deductions ride on top of the benefits most Marion County homeowners already carry:
- Homestead standard and supplemental deductions apply first if the property is your primary residence — see the homestead guide. For a totally disabled veteran under the new 100% deduction, taxable value goes to zero regardless, but keeping the homestead filing current protects you if your eligibility ever changes.
- The over-65 deduction and credit have their own income and value thresholds, filed separately with the same auditor's office. Our Marion County over-65 walkthrough covers the math — and note the new $250 veteran credit for those 62 and older is a distinct benefit from the over-65 program.
- Wartime + total-disability benefits have always required qualifying for each separately; the same logic carries into the restructured system.
The full menu of everything stackable is in our complete deductions and exemptions list.
Surviving spouses
HEA 1210 extends the total-disability benefit to an eligible surviving spouse who does not remarry — including spouses of veterans who would have qualified. The filing runs through the same Form 12662 process at the auditor's office, with the marriage and death documentation noted above. If your spouse's deduction was on the parcel when they passed, verify with the auditor that the benefit continued rather than silently dropping off; deductions falling away after a title change is one of the most common errors on Marion County bills.
Verify before the window closes
Verify what's actually on your parcel before you assume anything is filed: Property Lookup shows your current deductions, assessed value, and taxing district in one view, and Marion County parcel pages let you confirm the record card matches reality. Then get Form 12662 — with your VA letter and DD-214 — to the auditor well before December 30, 2026, and calendar a check of your spring 2027 bill to confirm the benefit landed.
