How Do Candidates Raise Money? Sources, Limits, and Disclosure

Federal candidates raise money from five main sources: individual donors, political action committees (including Super PACs), political party committees, their own personal funds, and — for presidential candidates only — a government matching-fund program. The Federal Election Campaign Act sets a cap on how much any one person or group can give directly to a campaign while leaving certain kinds of outside spending uncapped. For the 2025–2026 cycle, an individual can give up to $3,500 per election to a federal candidate, and those limits reset for inflation every two years.1Federal Election Commission. Contribution Limits for 2025-2026 Every source below sits inside that framework, but each one plays by different rules.

Individual Donations

Private citizens supply the bulk of most campaign budgets. Under federal law, no person may give more than $3,500 to a single candidate’s campaign for any one election during the 2025–2026 cycle.2Office of the Law Revision Counsel. 52 USC 30116 – Limitations on Contributions and Expenditures The primary and the general count as separate elections, so a maxed-out supporter can effectively give $7,000 across both contests to the same candidate.

The same law caps giving to other political entities each year: $5,000 to any single PAC, $10,000 combined to state, district, and local party committees, and $44,300 to a national party committee. Another $132,900 per year can go to special national party accounts earmarked for conventions, headquarters buildings, or election recounts.3Federal Election Commission. Contribution Limits Chart 2025-2026

Disclosure turns on a $200 threshold. If your total giving to one campaign stays at $200 or less across the cycle, the campaign keeps your information internally and leaves your name off public reports.4eCFR. 11 CFR Part 104 – Reports by Political Committees and Other Persons Cross that line and your name, address, occupation, and employer become part of the public record. Campaigns and reporters use that boundary as the practical divide between “small-dollar” and “large-dollar” donors, and the volume of unitemized small-dollar receipts is often read as a proxy for grassroots support.

Online Small-Dollar Fundraising

The mechanics of individual giving changed dramatically in the last decade. Platforms like ActBlue on the Democratic side and WinRed on the Republican side let campaigns collect $5 and $25 contributions from millions of supporters with a few clicks. WinRed alone processed $1.8 billion from 4.5 million individual donors during the 2024 cycle, with the average donation dropping to $23.

The practical result is that a candidate with a strong online following can outraise one relying on maxed-out wealthy donors. Recurring monthly donations are especially valuable because they generate predictable cash flow. Every dollar collected still counts against the $3,500-per-election individual limit, but most online donors never come near the ceiling. The infrastructure isn’t free: both platforms charge processing fees, and campaigns spend heavily on digital ads to drive donation traffic.

PACs, Super PACs, and Hybrid PACs

A traditional political action committee pools contributions from members of a corporation, union, or interest group and gives directly to candidates. To qualify as a “multicandidate” PAC — the most common type — a committee must have been registered for at least six months, received contributions from more than 50 people, and made contributions to at least five federal candidates. A qualifying multicandidate PAC can give up to $5,000 per candidate per election.5eCFR. 11 CFR 110.2 – Contributions by Multicandidate Political Committees The same disclosure rules that cover individual donations cover PAC giving.

Super PACs work on completely different terms. After the Supreme Court’s 2010 ruling in Citizens United v. FEC, which held that independent political spending is protected speech and cannot be capped, a class of committee emerged that can raise unlimited amounts from individuals, corporations, and unions.6Federal Election Commission. Citizens United v. FEC The tradeoff is strict. A Super PAC may never give money to a candidate or coordinate its spending with any campaign. It can only make independent expenditures, such as running its own ads for or against a candidate. Coordination between a Super PAC and a campaign exposes both to serious legal consequences.

A less familiar hybrid, called a Carey Committee, splits the difference. These groups keep two separate bank accounts. One operates under normal PAC contribution limits and can give directly to candidates. The other accepts unlimited funds but may only be used for independent expenditures.7Federal Election Commission. Registering as a Hybrid PAC The wall between the accounts must be airtight; money from the unlimited side cannot fund direct contributions or coordinated spending.

501(c)(4) “Dark Money” Groups

Not every dollar flowing into an election comes through an entity that discloses its donors. Certain tax-exempt organizations, particularly 501(c)(4) “social welfare” groups, can spend on election-related activity without publicly revealing who funds them. Federal tax rules require these organizations to keep donor names and addresses on file, but that information goes only to the IRS on request, not into any public filing.8IRS. Instructions for Schedule B (Form 990)

The legal constraint is that political activity cannot be the group’s primary purpose. The IRS evaluates that by looking at whether political expenditures make up a majority of total spending. As long as the group spends more on social welfare, issue advocacy, or community programs than on election activity, it can run ads that clearly favor or oppose candidates without ever naming its funders publicly. That’s where the term “dark money” comes from. Critics say it undermines the transparency the disclosure laws were built to create. Defenders say it protects donors’ associational privacy.

Political Party Committee Support

National and state party committees back their nominees two ways: modest direct contributions and much larger coordinated expenditures. Coordinated expenditures cover things like polling, media buys, and voter outreach that the party pays for in consultation with the campaign. Federal law ties these limits to the office and, for Senate races, to the state’s voting-age population.

For 2025, coordinated expenditure limits run from $63,600 for a House nominee in a multi-district state up to $3,946,100 for a Senate nominee in the largest states.9Federal Election Commission. Coordinated Party Expenditure Limits Adjusted for 2025 In single-district states, the House limit rises to $127,200. These figures adjust yearly for inflation. Beyond coordinated spending, party committees run voter registration drives, get-out-the-vote operations, and generic party advertising that benefits everyone on the ticket without counting against any single candidate’s limits.

Joint fundraising committees add another tool. When a candidate, a national party committee, and several state parties combine forces for one fundraiser, a written agreement spells out how each dollar gets split.10eCFR. 11 CFR 102.17 – Joint Fundraising by Committees Other Than Separate Segregated Funds A donor writes one large check, and the fundraising committee allocates portions to each participant under the pre-set formula, returning any amount that would push the donor over a limit.

Personal Funds and Self-Funding

A candidate can bankroll their own campaign with no dollar limit. The Supreme Court settled that in 1976 in Buckley v. Valeo, holding that capping a candidate’s personal spending violates the First Amendment because it directly restricts political expression.11Justia Supreme Court Center. Buckley v. Valeo, 424 U.S. 1 (1976) The candidate still reports every dollar to the FEC, whether it enters the campaign as a contribution the candidate does not expect back, or as a loan the campaign can later repay.

The loan path used to carry a meaningful cap: campaigns could only use $250,000 in post-election donations to repay a candidate’s personal loans. The Supreme Court struck that cap down in 2022 in FEC v. Ted Cruz for Senate, holding it unconstitutionally burdened candidates who wanted to loan money to their own campaigns. A candidate can now loan any amount and be fully repaid using contributions raised after Election Day. Critics say this creates a corruption risk because post-election donors know exactly whom they are enriching. The Court found no evidence such arrangements had produced actual corruption.

Self-funding is still a gamble. Voters sometimes punish candidates who look like they’re buying a seat, and personal money spent on a losing race is simply gone. The candidate also has to show the funds are genuinely personal, not money funneled through them by someone else to skirt the contribution limits.

Who Cannot Contribute

Federal law flatly bars several categories of people and organizations from giving to any federal campaign. Getting this wrong can lead to fines, criminal prosecution, or both.

Campaigns are responsible for screening contributions against these prohibited sources. Accepting a donation from a foreign national or a federal contractor, even unknowingly, can trigger an FEC enforcement action. Most campaigns build compliance checks into their donation processing, but mistakes still happen, especially when money moves through intermediaries.

Presidential Public Financing

Presidential candidates have one option no one else on the federal ballot shares: a government matching-fund program paid for by the $3 checkoff on individual income tax returns. During the primaries, a candidate qualifies by raising more than $5,000 in matchable contributions in each of at least 20 states, with only the first $250 of any donation counting.15Federal Election Commission. Commission Certifies Primary Matching Fund Payments Once certified, the government matches those small-dollar contributions dollar for dollar, up to $250 per donor.

The catch is that taking matching funds means agreeing to overall primary spending limits. In the general election, major-party nominees can accept a lump-sum grant meant to cover the entire campaign, but accepting it means raising no additional private money.16Office of the Law Revision Counsel. 26 USC 9004 – Entitlement of Eligible Candidates to Payments The grant hasn’t kept pace with modern campaign costs. No major-party presidential nominee has taken general-election public funding since 2008, when private fundraising began outstripping the grant by hundreds of millions of dollars. The program still exists, and some primary candidates still use the matching funds, but it plays a marginal role in today’s presidential races.

Disclosure and Penalties

Every campaign committee, PAC, and party committee files regular financial disclosure reports with the FEC. Quarterly filers in 2026 face deadlines on April 15, July 15, and October 15 for the first three quarters, plus a pre-general report due October 22 covering activity through October 14.17Federal Election Commission. 2026 Quarterly Reports Committees tied to a primary file an additional report 12 days before that primary. Every contribution received and every expenditure made appears on these reports, which form the public record journalists, opponents, and voters use to follow the money.

Missing a deadline gets expensive. The FEC calculates fines using a formula that weighs whether the report was election-sensitive, how late it was, the size of the financial activity involved, and how many prior violations the committee has.18Federal Election Commission. Calculating Administrative Fines For a late election-sensitive report, the base penalty starts above $1,600 and climbs by more than $200 for each additional day, with each prior violation adding another 25 percent. A committee that never files a non-election-sensitive report at all can be fined an amount equal to the total activity that should have been reported. Those numbers compound quickly and can cut into a campaign’s operating budget.
