Due dates, tax bills, and penalties

Tax bills are mailed on or about April 10 each year. Spring and fall payment coupons are included in that mailing, and there is no fall mailing.

The Spring property tax due date is May 11, 2026. The Fall property tax due date is November 10, 2026. Payments sent by mail are considered on time if the envelope is postmarked on or before the tax due date, but postmarks do not apply to properties going to tax sale.

If a payment is missed, a 5% penalty is added to the unpaid balance when there are no other delinquencies and the taxes are paid within 30 days of the due date. After 30 days, or when other delinquencies exist, the penalty is 10% of the unpaid balance.

Scam alert: The Allen County Treasurer's Office does not text or call taxpayers who are delinquent on property taxes.

Payment plans and automatic payments

Allen County offers payment options for taxpayers who want to spread payments out or automate installments. These options do not extend legal tax due dates.

  • Spring/Fall Auto Debit authorizes spring or fall installments to be deducted from a checking account on the property tax due day.
  • Recurring scheduled payments allow a specified amount to be deducted each month from a checking or savings account.
  • The recurring payment plan is for paying taxes ahead, not for extending due dates or paying delinquent tax.
  • Monthly pay plan access requires account registration in the payment portal.

Tax bill copies, receipts, and payment verification

Users can reprint a tax bill through Public Access Tax Information or Low Tax Info. The Treasurer's FAQ states there is no charge to reprint a tax bill.

For mailed payments, a bank statement showing the payment acts as the receipt. For in-person payments, bring the full tax bill so the Treasurer's Office can stamp the bill after collecting the payment coupon.

To verify that a payment has posted, use Low Tax Info to search by name, property address, duplicate number, or parcel number. The Treasurer's Office can also verify payment status by phone when the duplicate number is available.

Deductions, credits, and tax bill estimates

The Allen County Auditor's Office handles property tax deductions and credits. The Auditor processes benefit forms that may reduce a property assessment or tax bill when the owner qualifies.

Homeowners may apply online or in person for the Homestead Deduction / Credit, Over 65 Credit, and Blind / Disabled Credit. Several deductions were eliminated effective January 1, 2025 for taxes payable in 2026, and some prior deductions were replaced by credits.

Allen County also provides tax bill calculator information for users who want to estimate a tax bill. The Indiana Gateway tax bill estimator gives estimates only and should not be treated as a statement of true tax liability.

Mailing address changes

Mailing address changes are handled by the Allen County Auditor's Office. The online change form asks for property information, the new mailing address, owner information, email address, phone number, and an electronic signature.

Submitting a primary residence address change may affect deductions on a former property, so review any deduction needs after the address change is processed.

Delinquent taxes and tax sale information

A property with a balance due from the spring of the prior year or before is eligible for tax sale. Allen County states that tax sale notices are sent in July and a $45 fee is applied at that time.

If a property is delinquent for three or more installments, it is eligible for tax sale. The 2025 Tax Sale was scheduled for September 24, 2025, and tax sale details may change.

The delinquent property list is informational only and is not the tax sale list. It is subject to change daily and is not updated after posting for that year.
