N.D. Tax Department extends filing deadline to April 18

Tax Commissioner Cory Fong has announced that North Dakota's individual income taxpayers have three extra days to file and pay their state income tax and still be considered on time.

"The IRS announced earlier that it was extending the due date from April 15 to April 18, 2011 for federal income tax returns or payments," said Fong.  "North Dakota will match the April 18 extended filing date for the state income tax returns and payments that are usually due on April 15."

The extended due date is in recognition of the Emancipation Day holiday in the District of Columbia, which is observed on April 15 this year.  By federal law, the District of Columbia holiday impacts tax deadlines in the same way as federal holidays.  The observance of April 15 as Emancipation Day provides all taxpayers with three extra days to file this year.  Taxpayers requesting an extension will have until October 17 to file their 2010 income tax returns.

"Because April 15 is not a holiday in North Dakota," said Fong, "The Tax Department will be open and staff will be available to help taxpayers with their questions." 

In addition to income tax returns and payments, the April 18 deadline also applies to extension requests, estimated income tax payments, and financial institution tax returns and payments normally due on April 15.  The extended deadline applies whether the returns or payments are submitted electronically (e-filed) or by mail. 

"Even though the date is extended this year, we encourage taxpayers to start preparing their returns now so that they have plenty of time to double-check their entries, including social security and bank routing information," said Fong.  "By double-checking the information, taxpayers can make sure the information is correct, and prevent delays in receiving their refund."
