In general, Section 527 political organizations are required to report tax-related information to the Internal Revenue Service (IRS). Other information, such as disclosure of contributions and expenditures, is reported to either the IRS or the Federal Election Commission (FEC) depending on whether the political organization is also a political committee. Those that are political committees report to the FEC; while political organizations that are not political committees report to the IRS. Section 527 political organizations include the entities colloquially known as "527s" or "527 groups" that have been controversial during recent election cycles. The following chart compares the timing of election activity reporting requirements imposed by the Internal Revenue Code and the Federal Election Campaign Act. Selected Legislation

No legislation has yet been introduced in the 111 th Congress that would amend the timing of the reporting requirements in the IRC or FECA.
One way that federal law regulates groups participating in election activities is by requiring them to report information on such things as their contributions and expenditures. Reporting requirements are imposed on "political organizations" by the Internal Revenue Code (IRC) and "political committees" by the Federal Election Campaign Act (FECA). Some of the requirements are similar; in which case, entities are generally subject to either the ones in the IRC (and report to the Internal Revenue Service) or those in FECA (and report to the Federal Election Commission). Included in the entities that report to the IRS are those colloquially known as "527s" or "527 groups." No legislation has yet been introduced in the 111th Congress that would affect the timing of the reporting requirements under the IRC or FECA.
