Hush money is not illegal by itself. Paying someone for their silence, through a settlement or nondisclosure agreement, is a routine and lawful part of resolving disputes in the United States. The payment becomes illegal when it attaches to something else: concealing a crime, interfering with a witness or investigation, violating campaign finance limits, falsifying business records, or evading taxes on the money that changes hands.
So the real question is rarely whether a payment for silence is legal in the abstract. It’s what the payment is for, how it’s documented, and who it affects.
When Paying for Silence Is Legal
Most hush money moves through a confidentiality or settlement agreement. A nondisclosure agreement is a contract: one side provides money, the other promises not to discuss specified information. Businesses use NDAs to protect trade secrets and proprietary data. They also appear routinely in resolving employment disputes, personal injury claims, and commercial disagreements that both sides want to keep out of court.
When an NDA resolves a legitimate claim between willing parties, both the agreement and the payment are lawful. The line sits between resolving a genuine dispute and using money to bury criminal conduct. Two parties agreeing to confidentiality for consideration is a contract. Paying someone to stay silent about your crime is something the law treats very differently.
What an NDA Cannot Silence
Even a lawful NDA has limits that people drafting hush money deals often underestimate. Federal and state law carve out categories of speech that no confidentiality clause can suppress.
The Speak Out Act
The Speak Out Act, signed in December 2022, makes pre-dispute nondisclosure and nondisparagement clauses unenforceable when the underlying dispute involves sexual assault or sexual harassment. A broad NDA signed as part of an employment contract, before any dispute arose, cannot later be used to stop someone from speaking about harassment or assault that violated federal, tribal, or state law.1Office of the Law Revision Counsel. 42 USC Ch. 164 – Speak Out Act The federal law does not void NDAs signed after a dispute has already surfaced; settlement agreements reached once allegations are on the table remain enforceable. It also does not reach trade secret protections.
Nearly 20 states have passed their own laws restricting NDAs in sexual harassment and assault contexts, and some reach further than the federal statute, including into post-dispute agreements.
Reports to the Government
No NDA can legally stop you from reporting a suspected crime or securities violation to a government agency. SEC Rule 21F-17(a) prohibits any person from taking any action to impede someone from communicating with the SEC about a possible securities law violation, including enforcing or threatening to enforce a confidentiality agreement.2eCFR. 17 CFR 240.21F-17 – Staff Communications The SEC has brought enforcement actions over NDA language that could discourage reporting, even where the company never tried to enforce it.
The Defend Trade Secrets Act gives immunity from civil and criminal liability to anyone who discloses a trade secret in confidence to a government official or an attorney for the purpose of reporting or investigating a suspected violation of law.3Office of the Law Revision Counsel. 18 U.S. Code 1833 – Exceptions to Prohibitions Any NDA that purports to override this immunity is unenforceable on that point.
When Hush Money Becomes a Crime
The payment itself usually isn’t the offense. The surrounding conduct is.
Obstruction of Justice
Paying someone to stay silent about criminal activity, especially where an investigation or court proceeding is active or anticipated, can amount to obstruction. Federal law makes it a crime to corruptly influence, obstruct, or impede the administration of justice in connection with court proceedings, carrying up to 10 years in prison.4Office of the Law Revision Counsel. 18 U.S. Code 1503 – Influencing or Injuring Officer or Juror Generally The word “corruptly” does the work. Settling a private dispute is not corrupt. Paying to keep someone from cooperating with a federal investigation is.
Witness Tampering
Paying a witness to change testimony, withhold evidence, or skip a court appearance is a separate and more serious crime. Federal law prohibits using intimidation, threats, or corrupt persuasion to influence, delay, or prevent testimony in an official proceeding, and the same statute covers paying someone to withhold records or other evidence. Convictions carry up to 20 years in prison. Destroying, altering, or concealing documents to keep them out of an official proceeding falls under the same provision and the same maximum.5Office of the Law Revision Counsel. 18 U.S. Code 1512 – Tampering with a Witness, Victim, or an Informant
Extortion and Blackmail
When someone demands money by threatening to expose you, the person making the threat is often the one committing a crime. Federal law punishes anyone who demands or receives money or anything of value by threatening to reveal another person’s violation of a federal law, with up to one year in prison.6Office of the Law Revision Counsel. 18 U.S. Code 873 – Blackmail The federal statute is narrow: it targets threats about federal law violations. Broader extortion, like threatening to release intimate photos or expose an affair, is prosecuted under state blackmail and extortion laws that exist in every state.
In a blackmail scenario, the person paying is the victim. The crime belongs to the one making the threat. But if you initiate a payment to keep someone quiet about your own criminal conduct, the picture changes, and obstruction or tampering liability may apply to you.
Falsifying the Books
A payment that would have been legal on its own can become criminal through the paperwork. Logging a hush money payment as a legal retainer, consulting fee, or any other fabricated line item is where many deals fall apart.
Federal law punishes anyone who knowingly falsifies or makes a false entry in any record or document with intent to obstruct a federal investigation or agency proceeding, with up to 20 years in prison.7Office of the Law Revision Counsel. 18 USC 1519 – Destruction, Alteration, or Falsification of Records The statute reaches any matter within a federal agency’s jurisdiction, not just pending cases. A hush money payment that touches federal taxes, a federally regulated bank, or any entity under federal oversight can bring falsified records within this provision.
Most states also criminalize falsification of business records. In some states, the offense is a misdemeanor on its own but becomes a felony when the false entry is made to commit or conceal another crime. The practical effect: even if the payment is legal, the way you record it can produce independent criminal exposure.
Campaign Finance Exposure
Payments to suppress damaging stories during a political campaign can collide with federal election law. The Federal Election Campaign Act defines a “contribution” as any gift, payment, or deposit of money or anything of value made for the purpose of influencing a federal election.8Office of the Law Revision Counsel. 52 USC 30101 – Definitions That definition is wide enough to pull in a hush money payment made to keep a scandal from derailing a candidacy.
The FEC applies an “irrespective test” to tell campaign expenses from personal ones. A payment that would have been made regardless of the candidacy is personal. A payment whose primary purpose was to protect the candidacy is campaign-related.9Federal Election Commission. Personal Use of Campaign Funds A six-figure payment made weeks before an election, about a matter that had sat dormant for years, is hard to explain as anything other than campaign-motivated.
Once a payment counts as a contribution, it is subject to strict limits. For the 2025–2026 cycle, an individual can give no more than $3,500 per election to a federal candidate.10Federal Election Commission. Contribution Limits 2025-2026 A large hush money payment classified as a contribution blows past that cap on its face. It must also be publicly disclosed. Routing it through a third party to hide the source compounds the violation.
Penalties scale with the amount and intent. A knowing and willful violation involving $25,000 or more in unreported or illegal contributions during a calendar year is a felony carrying up to five years in prison. Violations between $2,000 and $25,000 carry up to one year. The FEC can also pursue civil penalties of up to $10,000 or 200 percent of the amount involved, whichever is greater, for knowing and willful violations.11Office of the Law Revision Counsel. 52 USC 30109 – Enforcement
Tax Consequences on Both Sides
Tax law creates problems for both the person paying and the person receiving.
For the payer, the temptation is to deduct the payment as a business expense. Ordinary legal settlements can be deductible, but Congress carved out an exception: no deduction is allowed for any settlement or payment related to sexual harassment or sexual abuse if the settlement is subject to a nondisclosure agreement. The restriction also reaches the payer’s attorney’s fees for such settlements.12Internal Revenue Service. Certain Payments Related to Sexual Harassment and Sexual Abuse Taking the deduction anyway is tax fraud. Recipients, by contrast, are not barred from deducting their own attorney’s fees.13Internal Revenue Service. Section 162(q) FAQ
For the recipient, the IRS treats settlement proceeds as taxable income under the general rule that income from any source is taxable unless a specific exclusion applies.14Internal Revenue Service. Tax Implications of Settlements and Judgments Not reporting a settlement is tax evasion, and the confidentiality clause is not a defense.
The main exception: damages received on account of personal physical injuries or physical sickness are excluded from gross income, whether paid through a lawsuit or a settlement.15Office of the Law Revision Counsel. 26 U.S. Code 104 – Compensation for Injuries or Sickness Emotional distress alone does not qualify unless it stems from a physical injury. If the payment compensates something else, like reputational harm, embarrassment, or emotional distress without physical injury, the full amount is taxable.16Internal Revenue Service.
