Which organizations must file a Form 1120-POL?

An exempt organization that is not a political organization must file Form 1120-POL if it is treated as having political organization taxable income under section 527(f)(1).

When is Form 1120-POL due?

Form 1120-POL is due by the 15th day of the 3rd month after the end of the tax year. Thus, for a calendar year taxpayer, Form 1120-POL is due on March 15 of the following year. If any due date falls on a Saturday, Sunday or legal holiday, the organization can file the return on the next business day.

What to do next

  • Write down the date on the letter today.
  • Look the number up on irs.gov yourself. Don’t trust a link or phone number from anyone else.
  • If it says you owe money or proposes changes to your return, take it to a licensed CPA, EA or tax attorney before that date.
