Corporate Income Tax is paid on a company's taxable income, which includes revenue minus expenses. Expenses include cost of goods sold (COGS), general and administrative (G&A) expenses, selling and marketing, research and development, depreciation, and other operating costs. Every corporation that does business in North Dakota, has sources of income in North Dakota, and/or has federal unrelated business taxable income (UBTI) must file a Form 40 – Corporation Income Tax Return.

Filing requirements for non-apportioning ND corporations (business operating solely in the state of ND) are broken out as follows:
  • Corporations that do business in North Dakota or have sources of income in North Dakota: Every corporation that does business in North Dakota or has sources of income in North Dakota must file a Form 40 – Corporation Income Tax Return. A signed Form 40 is required along with a minimum of the first 6 pages of the Federal 1120 and any relevant schedules. The return is due on April 15 of each year. Date for fiscal filers is on or before the 15th day of the 4th month following the end of the tax year. (The date may vary if the due date lands on a weekend or state holiday.)
    • Parent and subsidiary corporations that file a federal consolidated tax return must file a state consolidated corporation income tax return using the combined report method.
  • Corporation that is tax exempt for federal income tax but has taxable income in North Dakota: A corporation that is tax exempt for federal income tax purposes and has federal unrelated business taxable income (UBTI) is required to file a Form 40 - Corporation Income Tax Return. A signed Form 40 is required along with a Federal Form 990-T. Returns of tax-exempt organizations UBTI are due on the 15th day of the 5th month following the close of the tax year. For cooperatives that the Federal 1120C is required, returns are due on the 15th day of the 9th month following the close of the tax year. (The date may vary if the due date lands on a weekend or state holiday.)
  • Corporations that are tax exempt for federal income tax purposes and has no taxable income in North Dakota: A corporation that is tax exempt for federal income tax purposes and has no federal unrelated business taxable income (UBTI) is tax exempt for North Dakota corporate income tax purposes and does not need to file a North Dakota return for that year.
Filing requirements for apportioning ND corporations (businesses doing business in multiple US states) can elect to file in one of the two ways: 
  1. The standard method is to utilize the standard apportionable formula, which identifies the percentage of ND property, payroll and sales attributed to the total taxable income. 

    ND Apportionment Formula- Property, Payroll and Sales

  2. Business can elect to use a 100% sales only factor, which remains in effect for a five-year period.  
Filing requirements for two or more corporations are conducting a unitary business (activities of two or more affiliated corporations depend upon, contribute to, or are integrated with each other) require a unitary combined report which includes:
  • The total apportionable income of all members of the unitary group.
  • Any/all affiliated corporations that have more than 50% of its voting stock owned directly or indirectly by a common parent, which is also a member of the group

Filing requirements for corporations operating on a world-wide basis follow the unitary concept which means the total apportionable income includes income of all affiliated companies of the unitary group, whether those companies are incorporated within or outside the U.S. A corporation may elect to apportion its income using the water’s edge approach. Under such an election, the corporation must comply with the following:

  • The election must be made on the return as originally filed.
  • The water’s edge election is binding for five consecutive years.
  • The water’s edge report must include the income and apportionment factors of the water’s edge group, 30% of foreign dividends, and 30% of net book income from 80/20 corporations. An 80/20 corporation refers to an affiliated corporation incorporated in the U.S., but having less than 20% of its property and payroll assigned to U.S. locations.
  • North Dakota taxable income is subject to an additional 3.5% surtax.
