Check clearing is an automated process that with the expeditied funds availability act checks clear quite quickly from the point they are deposited in the stream of clearing. Physical checks no longer need to be presented, only images of them. As such, the clearing process is extremely fast. this is the principal reason kiting is quickly discovered. Therefore your question is really a question about the effeciency of the tax collector to present your check. Typically your check would have been presented by now. you can contact the taxing body and confirm reciept. In the future you could sent those important payments by way of certified mail or overnight carrier to ensure reciept and your proof of payment.
