Hard money vs. soft money is the basic dividing line in American campaign finance: hard money is given directly to a candidate’s campaign and comes with strict per-donor limits, while soft money is raised outside those limits for party activity, issue advocacy, or independent spending by outside groups. In the 2025–2026 cycle, an individual can give a federal candidate $3,500 per election in hard money. That same individual can write a check of any size to a Super PAC. The distance between those two numbers is what most fights over money in politics are really about.
What Hard Money Is
Hard money is any contribution made directly to a federal candidate’s campaign committee to influence an election.1Office of the Law Revision Counsel. 52 USC 30101 – Definitions It funds the core work of a campaign: ads that name the candidate and tell voters to support or defeat them, staff salaries, travel, polling, and direct mail. Because the money goes straight to the candidate, it carries the tightest rules. Every dollar has to be tracked, reported to the Federal Election Commission, and kept within contribution limits that Congress adjusts for inflation every two years.2Office of the Law Revision Counsel. 52 USC 30116 – Limitations on Contributions and Expenditures
Individuals and traditional political action committees are the main sources of hard money. Corporations and labor unions cannot give directly to federal candidates from their treasuries, a ban that has applied to corporations since 1907 and to unions since decades later.3Office of the Law Revision Counsel. 52 U.S. Code 30118 – Contributions or Expenditures by National Banks, Corporations, or Labor Organizations They can only participate through a separate PAC funded by voluntary contributions from employees or members. Foreign nationals, meaning anyone who is not a U.S. citizen or lawful permanent resident, are barred from making any contribution in any federal, state, or local election, and it is a separate offense for an American to solicit or accept one on their behalf.4Office of the Law Revision Counsel. 52 USC 30121 – Contributions and Donations by Foreign Nationals Federal government contractors are also prohibited from giving to federal candidates and party committees.
What Soft Money Is
Soft money is money raised outside the federal limits and source restrictions that govern hard money. Before 2002, national political parties could accept unlimited donations from corporations, unions, and wealthy individuals for activities framed as party-building rather than support for a single candidate. Voter registration drives, get-out-the-vote work, and generic party-platform ads all qualified.
The Bipartisan Campaign Reform Act of 2002, known as McCain-Feingold, closed that pipeline for national party committees.5Legal Information Institute (LII) / Cornell Law School. Bipartisan Campaign Reform Act of 2002 National parties now can only raise and spend money that meets federal contribution limits and source rules.6Office of the Law Revision Counsel. 52 USC 30125 – Soft Money of Political Parties State and local party committees kept a narrower ability to use non-federal funds, provided the spending does not refer to a specific federal candidate.
State and local committees can also raise Levin funds, donations of up to $10,000 per person per year from sources that include corporations and unions where state law allows.7Federal Election Commission. Federal Election Activity and Paying Committee Expenses Levin funds pay for voter registration and get-out-the-vote work tied to federal elections. Each local committee has to raise its own; transfers between committees are not allowed, and foreign nationals cannot give Levin funds regardless of state law.
Hard Money Limits for 2025–2026
For the 2025–2026 cycle, the ceilings on hard money contributions are:8Federal Election Commission. Contribution Limits for 2025-2026
- Individual to candidate: $3,500 per election. Primary and general elections count separately, so one donor can give up to $7,000 total to a single candidate.
- Individual to national party committee: $44,300 per year, plus separate $132,900 annual accounts for nominating conventions, legal proceedings, and headquarters buildings.
- Individual to state or local party committee: $10,000 per year combined across all such committees.
- Multi-candidate PAC to candidate: $5,000 per election.
- Individual to PAC: $5,000 per year.
The inflation-adjusted figures reset in odd-numbered years based on the cost of living since 2001. The $10,000 state party limit is fixed by statute and does not adjust.
How Super PACs and Dark Money Changed the Soft Money Side
The Supreme Court’s 2010 decision in Citizens United v. FEC struck down the ban on corporations and unions spending their own funds on independent political communications, holding that independent spending does not create corruption or its appearance.9Federal Election Commission. Citizens United v. FEC Months later, a federal appeals court in SpeechNow.org v. FEC extended that reasoning to contribution limits, ruling that groups making only independent expenditures cannot be capped in what they accept.10Federal Election Commission. SpeechNow.org v. FEC (Appeals Court)
Together those rulings produced Super PACs. A Super PAC can accept unlimited amounts from individuals, corporations, and unions and spend without a ceiling to support or oppose candidates, on one condition: it cannot coordinate with the candidates it is trying to help. That is how a donor limited to $3,500 for a candidate’s own campaign can put seven or eight figures behind the same candidate through a separate committee.
A quieter channel runs through tax-exempt nonprofits, particularly social welfare organizations under Section 501(c)(4) of the tax code. These groups can engage in political activity as long as it is not their primary purpose. Unlike Super PACs, they generally do not have to disclose their donors, which is where the label “dark money” comes from. The combination of unlimited corporate contributions and donor anonymity has made this channel grow substantially since 2010.
The Coordination Rule That Separates the Two
The whole distinction between regulated hard money and less-regulated outside spending rests on coordination. If an outside group coordinates its spending with a candidate’s campaign, the spending is treated as a direct contribution and becomes subject to hard money limits and source restrictions. A Super PAC ad developed in consultation with the candidate’s team is not independent spending; it is an illegal in-kind contribution.
The FEC applies a three-part test that looks at the source of payment, the content of the communication, and the conduct of the people involved, and all three prongs must be met before spending is treated as coordinated.11Federal Election Commission. NPRM on Coordinated Communications In practice, campaigns and outside groups use legal counsel and firewalls to stay on separate sides of the line, and disputes usually turn on shared vendors, staff who switch sides, or leaked strategic material.
Disclosure
Federal candidates and political committees must register with the FEC once they hit certain fundraising thresholds and then file regular financial reports.12Federal Election Commission. Registration and Reporting Donors who give more than $200 in aggregate are listed by name, address, occupation, and employer in reports that anyone can search online. Super PACs register and disclose their donors the same way because they are political committees under federal law.
The transparency drops off with 501(c)(4) nonprofits and similar tax-exempt groups. They report their total political spending to the FEC but usually do not have to name their donors. That is the reporting gap the term “dark money” points to.
Penalties
Campaign finance violations carry both civil and criminal consequences. For a standard violation that is not knowing or willful, the FEC can negotiate a civil penalty up to the greater of $5,000 or the amount of the illegal contribution. If the violation was knowing and willful, the ceiling rises to the greater of $10,000 or 200 percent of the amount involved.13GovInfo. 52 USC 30109 – Enforcement Straw donor schemes, where contributions are funneled through someone else’s name, face a penalty of at least 300 percent of the amount involved.
On the criminal side, McCain-Feingold turned campaign finance offenses from misdemeanors into potential felonies. Violations involving more than $10,000 can bring up to two years in prison; those involving $25,000 or more can bring up to five.14United States Sentencing Commission. Report to the Congress: Increased Penalties for Campaign Finance Offenses Criminal prosecution requires proof that the defendant acted knowingly and willfully, so most enforcement moves through the FEC’s civil process rather than federal court.
