Political Organization Filing Requirements: Form 1120 POL Reporting by Organization that Did Not Report Required Items on Form 8871

What does a political organization that is not exempt because it did not file Form 8871 report on Form 1120-POL?

In addition to reporting its investment income as discussed in Form 1120-POL Reporting, the political organization reports its exempt function income (contributions, etc.) as other income.  It may deduct the expenses directly related to earning that income (such as fundraising expenses), but may not deduct its political campaign expenses.
