(Bismarck, ND) — Taxpayers who filed for an extension on their individual income tax returns this past spring have less than a week to file submissions. Those with a federal extension can submit their state returns without penalty through October 15th. Electronic filing is highly encouraged to meet the deadline, but paper returns will still be accepted if postmarked by the deadline date. Taxpayers also have the option to hand-deliver their returns to the North Dakota Office of State Tax Commissioner, located on the 8th floor of the State Capitol.
