When Are Tax Bills Mailed?

Allen County generally mails property tax bills on or about April 10 each year.

One important thing to remember:

Both the spring and fall payment coupons are included in the same mailing.

Allen County does not normally send another tax bill in the fall.

Keep the fall coupon when you receive your spring bill.

Didn’t Receive a Tax Bill?

Not receiving a tax bill doesn’t remove your responsibility to pay the taxes by the deadline.

If you:

Didn’t receive your bill
Lost your bill
Recently moved
Recently purchased the property
Need another copy

you can look up and reprint your property tax bill online.

What Happens If You Pay Late?

Late property tax payments are subject to penalties.

Allen County states that if you have no other delinquent taxes and pay within 30 days after the due date, a 5% penalty is generally added to the unpaid balance.

After 30 days—or if other delinquent taxes are already owed—the penalty is generally 10% of the unpaid balance.

Does the Postmark Count?

Yes.

For regular property tax payments, Allen County considers a payment timely when the envelope is postmarked on or before the tax due date.

The postmark rule does not apply to properties going to tax sale.

Recurring payments allow you to pay ahead throughout the year, but they do not extend the property tax deadline.

What If Your Mortgage Company Pays?

If your property taxes are included in your mortgage escrow, your mortgage company generally pays the spring and fall installments.

It’s still a good idea to verify that the county received the payment, especially after:

Refinancing
Changing mortgage companies
Buying a home
Paying off your mortgage

Can You Make Partial Payments?

Yes. Allen County accepts partial property tax payments.

However, the full amount must still be paid by the applicable deadline to avoid penalties on the unpaid balance.

Delinquent Property Taxes

Don’t ignore overdue property taxes.

Allen County states that parcels with a balance due from the spring of the prior year or earlier may become eligible for tax sale.

Additional notices, fees and costs can apply.

If you’re significantly behind, contact the Treasurer at 260-449-7693.

Before the Deadline

Before each spring and fall deadline:

Check the exact due date for the current year.
Verify the amount due.
Check whether your mortgage company is paying.
Locate your payment coupon.
Allow enough time for mailed payments.
Save your payment confirmation.
Verify that the payment posted.

Local Tip

Don’t wait for another tax bill before the fall payment. Allen County normally sends one bill in the spring containing both the spring and fall payment coupons.

Put the fall deadline on your calendar when the spring bill arrives, and check the Treasurer’s website for the exact due date for the current year.
