N.D. Admin. Code § 81-09-02-05 — Extension of due date for filing a return or paying tax

1. A taxpayer may request that the due date for payment of the tax be extended by a maximum of fifteen days. In addition, a taxpayer may request that the due date for filing a return be extended. However, if tax is due with the return, the due date for filing will only be extended by a maximum of fifteen days. 2. A taxpayer may request an extension of time either verbally or in writing. A verbal request must be made on or before the due date for paying the tax or filing the return. A written request must be received by the commissioner on or before the due date for paying the tax or filing the return. Both a verbal and written request must advise the commissioner as to why the extension of time is needed. 3. If a request for an extension of time is approved verbally, the taxpayer shall submit written notice to the commissioner confirming this fact within five days of the date the request was approved. If a request is not approved verbally, the commissioner shall promptly notify the taxpayer in writing as to whether the request is approved or denied. 4. If a request for an extension of time for filing a return is approved, the taxpayer shall compute and pay with the return extension interest at the rate of twelve percent per annum. The daily interest rate is .000333. Interest is computed from the original due date of the return to the date the tax is paid, which is the date the payment is mailed or an electronic payment is initiated.
