When is my sales tax return and sales tax payment due?

Your sales tax return and payment due date depend on your filing frequency. Most taxpayers are on either a quarterly, or a quarterly prepay reporting schedule. Quarterly taxpayers only pay once each quarter. Quarterly Prepay taxpayers make a payment every single month.
