We often get many phone calls close to the tax due date regarding why a payment is not showing posted or why a check has not cleared the bank.  While it is always recommended the taxpayer make sure their tax payment has been received and is posted properly, please give our staff ample time to post and process all of our payments from the various payment sources.

All payments are processed in the order they are received.  As the due date approaches our in-office cashiers get busy with walk-in customers and process mail received in between customers, in the date order in which it was received in our office.  Since our volume of mail naturally increases three fold at this time, it is not unusual for our staff to be anywhere from two days to two weeks behind in processing these payments.

All payments made using your checking account, regardless of the payment channel used, are subject to being removed after posted if the check or ACH fails to clear your account for any reason.

All payments made on the due dates or mailed with a postmark on the due date will be posted as on time payments regardless of when they are actually posted to our system.

To help you, we have put together an approximate posting timeline for the various payment options.  Please note Holidays will delay all posting by one to two business days.
