Political action committees, or PACs, are federally regulated groups that pool contributions from donors to support or oppose candidates, parties, and ballot measures. In federal politics, what a PAC can actually do depends on which kind of PAC it is: a traditional committee tied to a corporation or union, an independent issue or leadership committee, a Super PAC that spends without limits but never gives to candidates, or a hybrid that runs both books at once. The Federal Election Commission sets the rules, and the differences between the categories decide who can donate, how much, and where the money can go.
The Four Main Types of Federal PACs
Separate Segregated Funds
A separate segregated fund (SSF) is a PAC formally attached to a sponsoring organization, typically a corporation, labor union, or trade association. The sponsor can pay the PAC’s administrative and fundraising costs out of its own treasury, so more of the donor money flows into political activity rather than overhead.1Office of the Law Revision Counsel. 52 USC 30118 – Contributions or Expenditures by National Banks, Corporations, or Labor Organizations
The trade-off is a narrow pool of donors. A corporate SSF may solicit only its stockholders, executive and administrative personnel, and their families. A union SSF is limited to members, executive and administrative personnel, and families.2eCFR. 11 CFR 114.5 – Separate Segregated Funds
Nonconnected Committees
Nonconnected committees operate on their own, without a sponsor. They usually form around a policy cause, an ideology, or an officeholder’s political goals. Because no parent organization covers overhead, every dollar of administrative and fundraising expense comes out of the contributions the PAC raises. In exchange, they can solicit any member of the general public who is legally allowed to give in federal elections.3eCFR. 11 CFR 100.5 – Political Committee
Leadership PACs are a familiar subtype. These are nonconnected committees established, financed, or controlled by a sitting federal officeholder or candidate but not authorized by that person’s campaign committee.4Federal Election Commission. Leadership PACs Identify Their Sponsors on FEC Form 1 Members of Congress often use them to raise money for other candidates and build relationships inside their party. The sponsoring officeholder has to be named on the committee’s Statement of Organization.
Super PACs
Independent expenditure-only committees, commonly called Super PACs, grew out of two 2010 court decisions. In Citizens United v. FEC, the Supreme Court held that restricting independent political expenditures by corporations and unions violated the First Amendment.5Justia Law. Citizens United v. FEC, 558 US 310 (2010) Weeks later, the D.C. Circuit ruled in SpeechNow.org v. FEC that contribution limits could not constitutionally apply to groups making only independent expenditures, reasoning that such spending “cannot corrupt or create the appearance of corruption.”6Federal Election Commission. SpeechNow.org v. FEC The result: a committee that can accept unlimited contributions from individuals, corporations, and unions.
The strict condition is that Super PACs cannot give money to federal candidates or their campaign committees.7Federal Election Commission. Limits on Contributions Made by Nonconnected PACs Their spending has to be independent, meaning uncoordinated with any campaign. If the FEC finds the spending was coordinated, it becomes an in-kind contribution to the candidate, which is prohibited.8Federal Election Commission. NPRM on Coordinated Communications
Hybrid PACs
A hybrid PAC operates as both. Under the 2011 ruling in Carey v. FEC, a nonconnected committee can maintain two bank accounts: a federal account that accepts contributions within normal FEC limits and makes direct candidate contributions, and a non-contribution account that takes unlimited money and spends only on independent expenditures.9Federal Election Commission. Nonconnected PACs – Part 1 The wall between the two must hold. Money from the non-contribution account can never be used, directly or through coordination, to support a candidate.10Federal Election Commission. Advisory Opinion 2022-11
How Much Money Can Move Through a PAC
Contribution limits run on a two-year election cycle, with several figures indexed for inflation. For the 2025–2026 cycle, an individual may give up to $5,000 per year to any traditional PAC, whether an SSF or a nonconnected committee.11Federal Election Commission. Contribution Limits for 2025-2026 That cap applies per PAC, so a donor can support multiple committees without the amounts combining against one limit.
What a PAC can give out to a candidate depends on whether it qualifies as a multicandidate committee. That status kicks in after the committee has been registered with the FEC for at least six months, has received contributions from more than 50 people, and has made contributions to five or more federal candidates.12Office of the Law Revision Counsel. 52 USC 30116 – Limitations on Contributions and Expenditures A qualified multicandidate PAC can give up to $5,000 per candidate per election. A PAC that hasn’t met all three tests is capped at $3,500 per candidate per election for the 2025–2026 cycle, the same limit that applies to an individual donor.11Federal Election Commission. Contribution Limits for 2025-2026
Super PACs raise unlimited sums but contribute nothing to candidates. Hybrid PACs follow both sets of rules depending on which account holds the funds.
Who Cannot Contribute
Some donors are off-limits regardless of PAC type. Foreign nationals, including foreign governments, foreign corporations, and individuals who are neither U.S. citizens nor lawful permanent residents, are barred from making any contribution or donation in connection with a federal, state, or local election. Soliciting or accepting such a contribution is equally illegal.13Office of the Law Revision Counsel. 52 USC 30121 – Contributions and Donations by Foreign Nationals
Federal contractors face a separate ban. Any person or entity negotiating or performing a federal contract cannot contribute to a political party, committee, or candidate for the duration of the contract, and the prohibition covers the contractor’s own funds, not just funds tied to the contract. Soliciting from a federal contractor is also unlawful.14eCFR. 11 CFR 115.2 – Prohibition
Forming a PAC and the Treasurer’s Role
A PAC has to register with the FEC within 10 days of being formed. Before it can take in a single contribution or spend a single dollar, it must designate a treasurer. If the treasurer is unavailable and no assistant treasurer has been named on the Statement of Organization, all activity stops.15Federal Election Commission. Treasurer’s Liability
That role carries real exposure. The treasurer deposits receipts within 10 days, authorizes expenditures, monitors contribution limits and prohibited sources, and files every report on time. Consultants and staff can do the daily work, but legal responsibility stays with the treasurer. In FEC enforcement actions, both the committee and the treasurer are named as respondents, and a treasurer who knowingly violates the law, recklessly ignores duties, or deliberately avoids learning the facts can be held personally liable.15Federal Election Commission. Treasurer’s Liability
Public Disclosure
Every political committee files periodic reports with the FEC disclosing all receipts and disbursements. Reports are cumulative for the calendar year and filed either monthly or quarterly depending on the committee’s choice and the election cycle.16eCFR. 11 CFR 104.3 – Contents of Reports
Any individual whose contributions total more than $200 in a calendar year has to be itemized by name, mailing address, occupation, and employer.17Office of the Law Revision Counsel. 52 USC 30104 – Reporting Requirements Committees have to make a good-faith effort to gather that information, and if a donor doesn’t supply it, the treasurer must follow up in writing within 30 days.18Federal Election Commission. Individual Contributions to Federal Candidates and Committees The reports are posted in the FEC’s public database, so anyone can see who is funding a given committee.
Penalties for Getting It Wrong
Campaign finance violations carry civil and criminal consequences that scale with the amount involved and whether the conduct was intentional. On the civil side, the FEC can resolve matters through conciliation agreements imposing penalties of up to $10,000 or 200% of the amount at issue, whichever is greater. If the matter goes to court, the penalty can reach the same threshold. The FEC also runs an Administrative Fines Program with mandatory civil penalties for late or missing reports.19Federal Election Commission. Committees Fined for Filing Reports Late
Criminal charges are reserved for knowing and willful violations. When the violation involves $25,000 or more in contributions, expenditures, or reporting failures in a calendar year, the maximum penalty is five years in prison, a fine, or both. Violations between $2,000 and $25,000 carry up to one year of imprisonment.20GovInfo. 52 USC 30109 – Enforcement Routing contributions through straw donors to hide the true source triggers steeper penalties, including mandatory fines of at least 300% of the amount involved.
