Political action committees, known as PACs, are organizations that pool contributions and spend the money to influence federal elections. They come in several forms, and the form dictates almost everything else: who is allowed to donate, how much a donor can give, how much the PAC can hand to a candidate, and whether it can work with a campaign at all. For the 2025–2026 cycle, a standard PAC can give a candidate up to $3,500 per election, a qualified multicandidate PAC can give $5,000, and a Super PAC can raise unlimited sums but cannot give a candidate a single dollar.
The Main Types of PACs
Federal election law recognizes several distinct PAC structures. The differences are not cosmetic. Each type carries its own fundraising pool and its own restrictions on what the money can do.
Separate Segregated Funds
A separate segregated fund (SSF) is a PAC set up by a corporation, labor union, or trade association. The parent organization pays the committee’s overhead, but the political money has to come from a narrow group. Corporate SSFs solicit shareholders and management-level employees; union SSFs solicit their members. Treasury money from the parent cannot flow into the PAC’s political account.1Federal Election Commission. Who Can and Cant Contribute
Nonconnected Committees
A nonconnected PAC has no parent corporation or union standing behind it. It can solicit contributions from the general public, but it also has to pay its own rent, salaries, and fundraising costs from the money it raises.2Federal Election Commission. Understanding Nonconnected PACs Issue-focused groups, ideological organizations, and single-candidate supporters commonly use this structure.
Leadership PACs
Members of Congress and other political figures often set up leadership PACs to support other candidates and build influence within their party. A leadership PAC is legally separate from the sponsoring politician’s own campaign committee, and its funds cannot be routed back to pay for that politician’s personal federal campaign.3Federal Election Commission. Leadership PACs
Super PACs
Super PACs, formally called independent expenditure-only committees, emerged from the Citizens United v. FEC and SpeechNow.org v. FEC decisions. They can accept unlimited contributions from individuals, corporations, unions, and other PACs. The trade is absolute. A Super PAC cannot give any money directly to a candidate and cannot coordinate its spending with any campaign.1Federal Election Commission. Who Can and Cant Contribute In practice, Super PACs spend on television, digital ads, and other messaging that supports or opposes candidates without the candidate’s involvement.
Hybrid PACs
A hybrid PAC, sometimes called a Carey Committee after the Carey v. FEC decision, splits the difference by maintaining two separate bank accounts. One follows normal contribution limits and can give directly to candidates. The other accepts unlimited funds from individuals, corporations, and unions and can only be used for independent expenditures. The wall between the two accounts has to be airtight, and money in the unlimited account can never be used to make contributions to candidates.4Federal Election Commission. Nonconnected PACs Part 1
Who Can and Cannot Contribute
U.S. citizens and lawful permanent residents (green card holders) are the primary funding source for traditional PACs. Federal law flatly prohibits contributions from foreign nationals who lack permanent residency, and the ban covers indirect financial support as well as direct donations at every level of U.S. elections.1Federal Election Commission. Who Can and Cant Contribute
Corporations and labor unions cannot contribute from their treasuries to traditional candidate-focused PACs. They can set up SSFs that raise money from eligible individuals within the organization, and they can send unlimited treasury funds to Super PACs and to the non-contribution accounts of hybrid PACs.1Federal Election Commission. Who Can and Cant Contribute
Federal government contractors face a separate ban. Anyone under contract with the U.S. government, whether for personal services, materials, or building projects paid with appropriated funds, cannot make political contributions from the start of contract negotiations through the completion or termination of the contract. The prohibition covers the contractor itself and extends to promises of future contributions. A contractor’s employees can still contribute personally, and the contractor can establish and administer an SSF.5Office of the Law Revision Counsel. 52 US Code 30119 – Contributions by Government Contractors
Contribution Limits for 2025–2026
The dollar amounts a PAC can give, and receive, depend on whether it qualifies as a multicandidate committee. The FEC adjusts some of these limits for inflation every two years.
Non-Multicandidate PACs
A standard PAC that has not yet earned multicandidate status can contribute up to $3,500 per candidate per election for the 2025–2026 cycle.6Federal Election Commission. Contribution Limits for 2025-2026 Limits apply separately to each election, so a PAC contributing the maximum in both the primary and the general can give a single candidate $7,000 across the two contests.7Office of the Law Revision Counsel. 52 USC 30116 – Limitations on Contributions and Expenditures Individuals donating to a non-multicandidate PAC are capped at $3,500 per election.
Multicandidate PACs
A PAC qualifies for multicandidate status once it has been registered for at least six months, received contributions from more than 50 people, and made contributions to five or more federal candidates.7Office of the Law Revision Counsel. 52 USC 30116 – Limitations on Contributions and Expenditures Once qualified, the PAC can give up to $5,000 per candidate per election. That figure is set by statute and is not indexed for inflation. Individuals can give a multicandidate PAC up to $5,000 per calendar year.6Federal Election Commission. Contribution Limits for 2025-2026
Super PACs and Hybrid PAC Non-Contribution Accounts
Because Super PACs never give money directly to candidates, no contribution limits apply on the receiving end. An individual, corporation, or union can write a check for any amount. The same rule applies to the non-contribution account of a hybrid PAC. The only constraint is complete independence from the candidates the committee supports.
Penalties for Going Over
Blowing past contribution caps carries real consequences. For a standard violation, the FEC can pursue a civil penalty up to the greater of $24,885 or the amount of the illegal contribution. If the violation was knowing and willful, the ceiling jumps to the greater of $53,088 or 200% of the contribution involved.8eCFR. 11 CFR 111.24 – Civil Penalties
The Independence Rule for Super PACs
The legal wall between Super PACs and candidates is the single most consequential rule in this space. A Super PAC that coordinates with a campaign turns its “independent expenditure” into an in-kind contribution, subject to the same dollar limits as any other PAC donation. For a committee spending millions on advertising, that reclassification can create massive violations overnight.
The FEC uses a three-part test to decide whether a communication counts as coordinated. It looks at who paid for it, whether the content is campaign-related, and whether the candidate’s team was materially involved in creating or distributing it. All three elements have to be present before the spending is treated as a coordinated contribution.
To stay on the right side of the line, PACs that share personnel with campaigns are expected to set up written firewall policies. The firewall must block the flow of information between the people working on the PAC’s communications and anyone currently or previously providing services to the candidate featured in those communications. The policy has to be in writing and distributed to every employee, consultant, and client it covers.9Federal Election Commission. Campaign Guide for Nonconnected Committees A written firewall is not an absolute shield. The FEC can still find coordination based on the facts, but the policy satisfies a regulatory safe harbor that makes enforcement much less likely.
Registration and Public Disclosure
Every PAC must register with the FEC within 10 days of becoming a political committee, which happens once it takes in contributions or makes expenditures exceeding $1,000 in a calendar year.10Office of the Law Revision Counsel. 52 USC 30103 – Registration of Political Committees From that point on, the committee enters a cycle of regular financial reporting that continues until it formally shuts down.
PACs must itemize every contribution over $200 from a single source within a calendar year, including the contributor’s full name, mailing address, occupation, and employer.11Federal Election Commission. Recording Receipts All disbursements have to be detailed as well, creating a public trail of where political money goes. The FEC publishes this information in a searchable online database, so anyone can look up who funds a committee and how that committee spends its money.
PACs choose either monthly or quarterly filing and have to stick with the same schedule for the entire calendar year. During election years, the regular schedule is interrupted by mandatory pre-election and post-election reports. Missing or late reports feed into the FEC’s Administrative Fine Program, which escalates penalties based on how sensitive the report was to an upcoming election, how late it was filed, how much money was involved, and how many prior violations the committee has on its record.12Federal Election Commission. Calculating Administrative Fines Each prior violation increases the fine by 25%.
