Depending on the circumstances, the Department may grant extensions for filing an excise tax return. The request must be made before the due date.
The Department can waive late return penalties under certain circumstances. If your return or payment is late and you feel you have a qualifying situation, you may request to have the penalty waived.
An account becomes delinquent when the due date for a tax return or other established liability has passed and the amount due remains unpaid.
