18 USC 209: Salary Supplementation Bans, Exceptions, and Penalties

18 USC 209 prohibits federal employees from receiving any salary, contribution to salary, or supplement to salary from a source outside the United States government as compensation for their official duties. The ban runs in both directions: the employee who accepts the payment and the person or organization who provides it face the same criminal exposure. A willful violation carries up to five years in prison and a fine of up to $250,000.¹

What the Statute Prohibits

The rule is simple in principle. If you work for the federal government, no one outside the government can pay you for that work. The prohibition reaches private companies, nonprofits, trade associations, and individuals, and it covers salary, stipends, bonuses, honorary payments, and expense arrangements that function as a supplement to your government compensation.¹

Labels do not control. An arrangement called a “consulting fee,” “research grant,” or “fellowship” still violates the statute if the money is really compensation for what the employee does in their government role. The Office of Government Ethics has laid out four elements that must all be present for a violation: the employee received pay or a salary supplement; it was given as compensation; the compensation was for services rendered as a government employee; and it came from a non-government source.² If any one of those elements is missing, the statute does not apply.

You do not need to have solicited the payment. Accepting it and keeping it is enough. And the person or entity on the paying end faces the same criminal statute the recipient does.

Who Is Covered

The statute applies to officers and employees of the executive branch, independent federal agencies, and the District of Columbia government. It covers career civil servants, political appointees, and people in temporary or part-time positions alike. Rank does not matter.¹

The most important carve-out is for special government employees and for anyone serving the government without compensation. A special government employee is someone appointed to perform temporary duties for no more than 130 days during any period of 365 consecutive days.³ Many advisory committee members and part-time consultants fall in this category, and their outside employers can keep paying them without either side violating the statute. This is the exemption that makes short-term government advisory work practical for private-sector professionals.

Military Personnel

Enlisted members of the Armed Forces are excluded from the statute’s definition of “officer or employee” entirely.³ For reserve and Space Force members called to active duty, the statute contains a specific allowance: a civilian employer can continue paying the salary or wages the member would have earned if military service had not interrupted the job.¹ A Reserve or National Guard officer who voluntarily serves on extended active duty beyond 130 days is reclassified as a regular government officer and loses the special government employee exemption.

Government Contractors

Contractors are generally not federal employees and sit outside this statute. Individuals whose work is so closely tied to government functions that they are effectively acting as government personnel may draw scrutiny under related ethics rules, but 18 USC 209 itself keys off employee status.

Payments That Are Not Prohibited

Not every payment from outside the government to a federal employee runs afoul of the statute. Several categories are permitted.

Pay for Work Unrelated to Your Government Job

Compensation for services that have nothing to do with your federal duties is allowed. A federal attorney can earn royalties on a novel. A policy analyst can teach an evening course on an unrelated subject and be paid for it. The test is whether the payment is for work rendered to the private party rather than for your government services.² Separate ethics regulations restrict compensation for teaching, speaking, and writing that relates to your official duties, so clearing an outside arrangement under 209 does not necessarily clear it under every other rule.

Former Employer Benefits

You can continue to participate in a bona fide pension, retirement plan, group life insurance, health insurance, accident insurance, profit-sharing plan, stock bonus plan, or other employee welfare or benefit plan maintained by a former employer.¹ This covers ongoing participation in vested plans, not new payments a former employer starts making after you enter government service.

State and Local Government Contributions

Contributions from the treasury of a state, county, or municipality are exempt.¹ The exception matters mainly for intergovernmental programs where state or local funds help support a position with federal duties.

Executive Exchange and Fellowship Programs

Relocation expenses for participants in executive exchange or fellowship programs do not violate the statute, provided the program was established by law or executive order, the appointment lasts no more than 365 days, and any extension does not exceed 90 additional days (or 365 days for overseas assignments).¹

Bona Fide Awards

An award recognizing public service or other meritorious achievement is not a prohibited supplement. The Office of Government Ethics has concluded that such awards carry no intent to compensate an official for performing specific duties and therefore fall outside the statute.⁴ An award chosen by an independent committee for career achievement is not the same thing as a payment dressed up as an award but timed and targeted to reward specific official actions.

Training-Related Travel From Nonprofits

Under a separate authority, 5 U.S.C. 4111, federal employees may accept travel expense payments from U.S. tax-exempt organizations when the travel is for training purposes. The exception is narrow and requires advance agency approval, but it comes up often for employees attending conferences or professional development events hosted by nonprofits.

Holding Two Government Jobs

Collecting pay from more than one federal position is a different question, governed by 5 U.S.C. 5533, which generally limits dual pay to no more than 40 hours of work per calendar week and includes several exceptions.⁵ The Office of Personnel Management can grant waivers in emergencies or other unusual circumstances.⁶

Penalties

The penalty depends on whether the conduct was willful. The statute draws a sharp line between someone who stumbles into a violation and someone who knowingly circumvents the rule.

Beyond criminal prosecution, the Attorney General can file a civil action seeking a penalty of up to $50,000 per violation or the amount of compensation the person received or offered, whichever is greater. A civil penalty does not foreclose criminal prosecution on the same conduct. The Attorney General can also seek an injunction ordering the conduct to stop.⁷

In serious cases, prosecutors may add charges under bribery or conspiracy statutes carrying steeper sentences. The collateral consequences reach further still: termination, loss of security clearance, and disqualification from future federal employment can follow a conviction or, in some cases, an unresolved investigation.

How Violations Come to Light

Investigations usually start inside the employee’s own agency. Each federal agency has an Office of Inspector General with statutory authority to investigate matters related to the agency’s programs and operations, including the power to issue subpoenas and take sworn testimony.⁹ Tips from coworkers, compliance reviews, and annual financial disclosure filings are common starting points.

Investigators look at financial records, employment agreements, and communications between the employee and outside entities. Credible evidence of a criminal violation can be referred to the Department of Justice. Not every case ends in charges. Agencies sometimes resolve matters through administrative action, particularly when the conduct was not willful.

When to Get Ethics Advice

The right time to ask is before you accept any financial arrangement that touches your government role. Agency ethics offices handle these questions routinely, and clearing an unsolicited offer with them before you take it is the simplest way to stay out of trouble. Private organizations that want to support government personnel through grants, fellowships, or sponsorships should get the same guidance, because many legitimate programs work inside the statute’s exemptions and the line between a lawful fellowship and a prohibited salary supplement is not obvious from the outside.

If you are already under investigation or have been told your financial arrangements are being reviewed, talk to a private attorney experienced in federal ethics law. The gap between a willful and non-willful violation is the gap between a misdemeanor and a felony, and how you respond early shapes which side of that line you end up on.
