Fort Wayne property taxes are billed by Allen County in two installments, due May 11 and November 10 for the 2026 tax cycle.1Allen County, IN. Treasurer Your total bill on a primary residence cannot exceed 1% of the home’s gross assessed value, and deductions plus recently restructured credits can reduce what you owe further if you file by January 15. The taxes fund Allen County schools, fire protection, law enforcement, libraries, and local infrastructure, and Senate Enrolled Act 1 of 2025 changed several of the deductions longtime homeowners have relied on, so a fresh review is worth your time.
How Your Bill Is Calculated
The Allen County Assessor sets a gross assessed value for your property using state guidelines and a yearly process called trending, which studies recent neighborhood sales to estimate current market value. Your assessed value can change from year to year without anyone visiting the house.2Department of Local Government Finance. Overview – Section: Annual Adjustments
From the gross figure, the county subtracts any deductions you’ve qualified for, leaving your net assessed value. That net number is multiplied by the combined tax rate for your taxing district, which reflects budgets approved by every overlapping local unit: county, city, township, school corporation, library, and any special districts.3Indiana Department of Local Government Finance. Citizens Guide to Property Tax
The Cap on What You Can Owe
Indiana’s constitution puts a ceiling on property tax bills relative to gross assessed value, applied automatically as a credit when the calculated tax would exceed the limit:4Justia. Indiana Code Title 6, Article 1.1, Chapter 20.6 – Credit for Excessive Property Taxes
- Homesteads: 1% of gross assessed value
- Other residential property, agricultural land, and long-term care property: 2%
- Commercial real property and personal property: 3%
For most Fort Wayne homeowners, the 1% cap is the number that matters. On a house with a gross assessed value of $200,000, your total property tax cannot exceed $2,000 in a year, no matter what the underlying rates would otherwise produce.
Deductions and Credits That Lower the Bill
Several deductions and credits either reduce your taxable value or subtract directly from your bill. Some of these changed under SEA 1 of 2025, so information you find on older pages may no longer be accurate.
Homestead Standard Deduction
If you own and live in the home as your primary residence, you qualify for the homestead standard deduction. It equals 60% of assessed value or $48,000, whichever is less.5Department of Local Government Finance. Legislative Changes Concerning Mortgage Deduction Repeal Under SEA 1 of 2025, the standard deduction is being phased down and will reach zero for taxes due in 2031, while the supplemental deduction rises to compensate.
Supplemental Homestead Deduction
Every homestead also receives a supplemental deduction automatically. For taxes first due in 2026, it equals 40% of what remains after the standard homestead deduction is subtracted, capped at 75% of the property’s gross assessed value.6Indiana General Assembly. Indiana Code 6-1.1-12-37.5 – Supplemental Deduction The percentage is higher than in prior years and will keep rising as the standard deduction phases down.
Over 65 Credit
The old Over 65 deduction under IC 6-1.1-12-9 was repealed for assessment dates beginning January 1, 2025.7Department of Local Government Finance. Legislation Affecting Deductions, Exemptions, and Credits SEA 1 replaced it with the Over 65 Credit under IC 6-1.1-51.3-1, a flat $150 subtracted directly from your tax liability rather than a reduction in assessed value. You must be at least 65 by December 31 of the year before you claim it, and your adjusted gross income from two years prior cannot exceed $60,000 for a single filer or $70,000 for a joint return.8Indiana General Assembly. Indiana Code 6-1.1-51.3-1 – Property Tax Credit The new credit has no cap on property assessed value and no residency requirement. A surviving spouse who is at least 60 and has not remarried can also claim the credit if the deceased spouse met the age requirement at the time of death.
Blind or Disabled Credit
Benefits for people who are blind or have a qualifying disability were similarly converted from a deduction to a credit under IC 6-1.1-51.3-2, effective for the January 1, 2025, assessment date. SEA 1 also removed the income limit that used to apply.9Allen County, IN. Credit for Blind or Disabled Persons You must own and live in the property and provide proof of disability, typically a Social Security award letter or a physician’s certification meeting SSA standards.
Veteran Deduction
Veterans with a service-connected disability rating of at least 10% and an honorable discharge can deduct $24,960 from assessed value.10Indiana General Assembly. Indiana Code 6-1.1-12-13 – Deduction for Veteran With Disability Documentation comes from a VA pension certificate, compensation award, or disability check. A surviving spouse can claim the same amount if the veteran met the requirements at death. File through the Allen County Auditor.
Filing Deadline and Moving Out
For deductions applied to the 2025 assessment payable in 2026, applications must be filed on or before January 15, 2026.11Department of Local Government Finance. Deductions and Credits Miss that date and the deduction won’t appear until the following year’s bill. Most deductions carry forward automatically after the first filing.
If you move out of a homestead, you have 60 days to notify the county auditor in writing. Skip that step and the county can back-tax you for the deductions you were no longer entitled to, plus a penalty.
Paying the Bill
Allen County mails tax bills around April 10 each year. The mailing includes both the spring and fall coupons; no separate fall notice goes out.1Allen County, IN. Treasurer The bill itemizes your gross assessed value, deductions applied, net assessed value, and how the total is split among the local units serving your property.
Payments for the 2026 tax year are due May 11 and November 10.1Allen County, IN. Treasurer The Treasurer accepts payments online through its portal (checking or savings account, credit card, Google Pay, PayPal), by phone at 1-844-576-2177, by mail to Allen County Treasurer, PO Box 2540, Fort Wayne, IN 46801-2540, and in person at the Rousseau Centre, 1 E Main Street, Suite 104, weekdays from 8 a.m. to 5 p.m. A drop box on Main Street on the north side of the Courthouse accepts check payments.

You can verify what’s on file, including which deductions were applied, through Allen County’s public access portal by searching your name, address, or Tax ID Number.12Allen County, Indiana. Public Access Tax Information
What Happens If You Pay Late
Missing a due date triggers automatic penalties. Pay within 30 days of the deadline with no prior delinquency on the parcel, and the penalty is 5% of the unpaid amount. Beyond 30 days, or if you already owe delinquent taxes or penalties on the parcel, the penalty is 10%.13Indiana General Assembly. Indiana Code 6-1.1-37-10 – Property Tax Penalty Each additional year of nonpayment adds another 10% penalty on the outstanding principal. Partial payments do not stop penalties from accruing or keep the property off the tax sale list.
A property becomes eligible for the county tax sale once it’s delinquent on three or more installments of at least $25 each. If it sells, you have one year from the sale to redeem it. Redemption requires 110% of the minimum bid if you act within six months, 115% if you wait longer, plus any amount the buyer paid above the minimum bid with 5% annual interest, plus any subsequent taxes the buyer covered. After the redemption period expires, ownership passes.
Appealing Your Assessment
If your assessed value looks too high, you can challenge it, but the window is short. When the county mails your Form 11 (Notice of Assessment) before May 1, you must file by June 15 of the assessment year. If the notice goes out on or after May 1, the deadline shifts to June 15 of the year the tax statement is mailed.14Indiana General Assembly. Indiana Code 6-1.1-15-1.1 – Taxpayers Appeal of an Assessment
You file Form 130 (Taxpayer’s Notice to Initiate an Appeal) with the Allen County Assessor. The process starts with an informal conference where you present evidence to the assessor’s office. Recent appraisals, comparable sales, and documentation of condition problems the assessor wouldn’t know about are the strongest material. The informal stage resolves more disputes than many people expect, so treat it seriously.15Department of Local Government Finance. Appeals Property Tax If the informal conference doesn’t produce a result you accept, the appeal moves to the Property Tax Assessment Board of Appeals, and from there to the Indiana Board of Tax Review and ultimately the Indiana Tax Court. A successful appeal produces a revised net assessed value that lowers future bills and can trigger a refund on overpayment.
A Note for Business Owners
If you run a Fort Wayne business, you have a separate obligation: a personal property tax return covering equipment, furniture, fixtures, and other tangible assets used in the business. The return is due May 15 on Form 103 (short or long version depending on complexity). Businesses claiming exemptions, including the under-$2,000,000 acquisition cost exemption, file the supplemental forms as well. Late filing draws penalties similar to those on delinquent real property taxes.
