How Property Tax Works

Allen County, Indiana operates under a property tax system that funds essential local services including schools, police and fire protection, libraries, parks, and county operations. Property taxes are calculated based on assessed value multiplied by the local tax rate, which varies significantly by location within the county due to different combinations of taxing districts.

For fiscal year 2025-2026, the base county tax rate is 0.11%, but your actual effective tax rate will be higher when combined with school district levies, municipal taxes, and special district assessments. Most property owners in Allen County can expect total effective tax rates ranging from 1.8% to 3.2% depending on their specific taxing districts. It's important to note that Indiana uses a complex system of tax credits that can reduce your final tax bill, but most require annual application and are not automatically applied.

Pro tip: If you pay through mortgage escrow, your lender splits these payments across your monthly mortgage. If you pay directly, set calendar reminders to avoid late penalties.
Section 4

Supplemental Tax Bills

Supplemental property taxes in Allen County are triggered by specific events that change property ownership or value during the tax year, primarily new construction completion, property improvements, or ownership transfers that reveal market value changes. Unlike the regular tax bills sent in April, supplemental taxes are calculated and billed when these triggering events occur.

Supplemental taxes are calculated by taking the difference between the old assessed value and new assessed value, multiplying by your property's tax rate, and prorating for the remaining months in the fiscal year. For example, if you complete a $50,000 home addition in September and your total tax rate is 2.5%, you would owe approximately $625 ($50,000 × 0.025 × 6/12 months remaining) in supplemental taxes. These bills are typically issued within 60-90 days of the triggering event and have their own due dates separate from regular property tax installments.

Section 5

Escrow & Property Taxes

Most mortgage lenders in Allen County require property tax escrow accounts, collecting monthly payments equal to 1/12th of your annual property tax bill plus insurance premiums. Your lender pays property taxes directly to the Allen County Treasurer on the May 10 and November 10 due dates, ensuring timely payment and avoiding penalties.

Lenders typically conduct annual escrow analyses each fall, comparing collected funds to actual tax bills paid. If your property taxes increase due to assessment changes or rate increases, your monthly escrow payment will be adjusted accordingly, with any shortage spread over 12 months. You can verify escrow payments by checking that your lender paid the correct amounts on time through the Allen County Treasurer's online payment portal, and you should receive annual escrow statements showing all transactions and the projected balance for the coming year.

Most credits require annual application through the Allen County Auditor's office.

Q: How does the Homestead Credit work? A: The Homestead Credit limits annual assessment increases to 10% for your primary residence and provides additional tax relief. You must file Form 43902 with the Auditor's office - it's not automatic. The credit continues until you sell or change primary residence.

Q: How often are properties reassessed in Allen County? A: Indiana conducts annual reassessments, with trending updates most years and comprehensive reappraisals every 4-6 years. The next major reassessment is scheduled for 2026.

Q: How do I appeal my assessment? A: File Form 130 with the Allen County Property Tax Assessment Board of Appeals by July 15 following the assessment date. Appeals are heard based on market value evidence you provide.

Q: What are the penalties for late payment? A: A 10% penalty is added to unpaid taxes after the due date, with additional interest accruing monthly. Delinquent taxes can result in tax sale after three years.

Q: Can I pay property taxes online? A: Yes, visit the Allen County Treasurer's website for online payments using bank accounts or credit cards. Convenience fees apply for credit card payments.

Q: Why did my taxes increase when my rate stayed the same? A: Tax increases typically result from higher assessed values, new special district levies, or loss of temporary credits. Your property may also have moved into a different tax bracket or lost eligibility for certain credits.

Q: What if I live in a special taxing district? A: Special districts (TIF zones, fire districts, parks) add extra levies to your tax bill. Your total rate includes county, school, municipal, and all applicable special district rates for your specific property location.

Q: Do I need to file for credits every year? A: Most credits require initial application only and continue automatically, but some (like Over-65 or Disabled Veteran) may require periodic renewal. Contact the Allen County Auditor's office to verify your specific credit requirements.
