Delaware Department of Revenue offers several payment options for taxpayers to settle their tax obligations. One of the most convenient methods is through their online payment portal, where taxpayers can pay using a debit or credit card. Additionally, electronic funds transfer is available for those who prefer direct bank payments. Taxpayers may also send a check or money order by mail, addressed to the appropriate office as specified on the tax forms. It is important to ensure that the payment is sent with the correct tax form to avoid any processing delays. For specific guidelines and detailed instructions on each payment method, as well as any associated fees, it is best to consult the official website of Delaware Department of Revenue for the most current information.
