Troubleshooting

Common Hamilton Township Tax Bill Problems and What to Do Next

Most tax bill problems are solved by matching the right account, right office, and right payment method before you pay twice or miss the grace period.

Bill not found online

Try block and lot, property address, prior owner name, and sewer account details. If you recently purchased the property, the record may still show the previous owner.

Owner name is wrong

The FAQ says a new owner may take six to eight weeks to appear. If more than eight weeks passed, contact the title company or attorney about county recording.

Never received a bill

Use WIPP to check payment status and amounts. Not receiving a bill does not make the due date disappear.

Payment crossed in mail

If you paid recently and received a delinquent notice, the township FAQ says the notice and payment may have crossed. Verify payment status before paying again.

Returned check

Replace funds only after the Tax Collector is notified, then follow certified-funds and returned-check fee instructions.
