  Question
 

Q. When is my tax return due?

  Answer
 

A. If you are required to pay your sales and use taxes or withholding tax by electronic funds transfer (EFT), you must use the TSC-BUS  to file your tax return electronically.  If you initiate a payment of sales and use tax through the TSC-BUS, to avoid possible penalty and interest charges, beginning on or after January 1, 2012, (due February 29th), ACH Debit taxpayers must initiate their transaction no later than midnight on, or before, the actual due date of the tax to be considered timely.

If you do not initiate payment of sales and use tax through the TSC-BUS, your tax return is due on or before the due date. If you initiate a payment of withholding tax,

To avoid possible penalty and interest charges, beginning on or after January 1, 2012, (due February 29th), ACH Debit taxpayers must initiate their transaction no later than midnight on, or before, the actual due date of the tax to be considered timely.  Your withholding return is due at the same time as your withholding tax payment.

For taxes you are not required to file electronically, your return is filed timely if received or if the date shown by the U.S. Post Office cancellation mark is on or before the due date.  If the due date falls on a Saturday, Sunday, or legal holiday, the next business day is the due date.
