BISMARCK – Taxpayers who filed for an extension on their individual income tax returns this past spring should be advised that the Tuesday, Oct. 15, deadline is approaching.

Those with a federal extension can submit their state returns without penalty through Oct. 15. To meet the upcoming deadline, electronic filing is encouraged; however, paper returns are also accepted and must be postmarked by Oct. 15. 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 during business hours, 8 a.m. to 5 p.m.

Note that interest will accrue on any unpaid balance from the April 15 deadline, and penalties will apply if the return is not filed by the extension deadline.

For assistance with state income tax returns, taxpayers can call the North Dakota Office of State Tax Commissioner at 328-1247 to speak with a representative.
