Prostitution is illegal across the United States with one narrow exception: licensed brothels operating in certain rural Nevada counties. Every other state and the federal government criminalize both selling and buying sex, and a conviction can reach well beyond jail time into immigration status, tax exposure, professional licensing, and housing. So when people ask is prostitution legal in the US, the honest answer is almost never, and the Nevada carve-out is smaller than most assume.
The Nevada Exception
Nevada is the only state where prostitution can be conducted legally, and only inside tightly regulated licensed brothels. The population threshold in NRS 244.345 bars counties with 700,000 or more residents from issuing brothel licenses.1Nevada Legislature. Nevada Revised Statutes 244.345 That rule alone makes prostitution illegal in Clark County, which contains Las Vegas and most of the state’s population, and limits legal brothels to a handful of rural counties that have chosen to allow them.
Everything outside those walls remains criminal. Engaging in prostitution or solicitation anywhere other than a licensed house is prosecuted under NRS 201.354.2Nevada Legislature. Nevada Code 201.354 – Unlawful for Customer to Engage in Prostitution or Solicitation for Prostitution Except in Licensed House of Prostitution A licensed worker who meets a client off-site is in the same legal position as a sex worker in any other state.
Workers inside licensed brothels must get a work card from the local sheriff’s office, which involves fingerprints and state and federal background checks.3Nye County Sheriff’s Office.

Nevada Administrative Code 441A.800 – Testing of Sex Workers Failing those requirements can cost a worker their permit or a brothel its license.
How Other States Punish Selling and Buying Sex
Every state besides Nevada criminalizes both sides of the transaction. Most treat a first offense as a misdemeanor. Fines commonly fall between $500 and $10,000 depending on the state, and jail time can reach a year. Solicitation statutes apply to buyers just as prostitution statutes apply to sellers, so paying for sex is a crime of its own.
Repeat convictions change the calculus. A second or third arrest often triggers felony charges, particularly when the earlier convictions fall inside a statutory lookback period. Felony prostitution carries state prison time measured in years and higher fines. Some states layer on location-based enhancements, pushing a misdemeanor into felony territory when the conduct happens near schools or parks.
A small number of states require sex offender registration for prostitution-related convictions, usually only when a minor is involved or when the defendant has stacked felony convictions. Registration rules differ enough that it is worth raising directly with a defense attorney when charges are filed.
Federal Crimes: Crossing State Lines and Online Platforms
Federal prostitution law targets conduct that crosses state or national borders. Under 18 U.S.C. § 2421, knowingly transporting someone across state lines with the intent that they engage in prostitution carries up to 10 years in federal prison.5Office of the Law Revision Counsel. 18 U.S. Code 2421 – Transportation Generally If the person transported is a minor, the statute imposes a mandatory minimum of 10 years and a maximum of life.6Office of the Law Revision Counsel. 18 USC 2423 – Transportation of Minors
The 2018 Allow States and Victims to Fight Online Sex Trafficking Act, known as FOSTA-SESTA, pulled online platforms into the same frame. It narrowed the immunity Section 230 of the Communications Act had given website operators, exposing them to both criminal prosecution and civil suits where conduct involves sex trafficking.7Office of the Law Revision Counsel. 47 USC 230 – Protection for Private Blocking and Screening of Offensive Material It also created a new federal crime: owning or operating a site with intent to promote or facilitate prostitution is punishable by up to 10 years in prison. Where the site facilitates prostitution for five or more people, or shows reckless disregard that its conduct contributes to sex trafficking, the maximum rises to 25 years, and victims of aggravated violations can sue in federal court.8Office of the Law Revision Counsel. 18 USC 2421A – Promotion or Facilitation of Prostitution and Reckless Disregard of Sex Trafficking
Pandering, Pimping, and Sex Trafficking
Third parties who profit from or facilitate someone else’s prostitution face far steeper penalties than the parties to the transaction. Pandering covers recruiting, coercing, or inducing someone into prostitution. In Nevada, pandering an adult without physical force is a category B felony punishable by 3 to 10 years in prison and fines up to $10,000; when the victim is a minor, it becomes a category A felony with a potential life sentence.9Nevada Legislature. Nevada Code 201.300 – Pandering and Sex Trafficking: Definitions, Penalties, Exception Labels and ranges vary by state, but the pattern is consistent.
Living off a sex worker’s earnings is a separate offense. In Nevada, taking money from the proceeds of someone else’s prostitution without providing something of value in return is a felony, with severity depending on whether force was used.10Nevada Legislature. Nevada Code 201.320 – Living From Earnings of Prostitute Other states use terms like “promoting prostitution” or “compelling prostitution” for comparable conduct.
At the federal level, sex trafficking sits at the top of the penalty structure. Trafficking charges apply when force, fraud, or coercion is used to compel someone into commercial sex, or whenever the victim is under 18, regardless of whether coercion was shown. Federal convictions carry a 15-year mandatory minimum, and life imprisonment where the victim is a child or where the offense involved kidnapping or serious bodily injury.
Where the Law Is Changing
No state has fully legalized prostitution outside Nevada’s brothel system, but the enforcement model is loosening in places.
Maine enacted LD 1435 in 2023, which eliminated the crime of engaging in prostitution for sellers while keeping it illegal to buy sex.11Maine Legislature. LD 1435 – An Act to Reduce Commercial Sexual Exploitation The law also increased penalties for buying sex from a child. Maine became the first state to formally decriminalize the sale of sex by statute rather than through prosecutorial policy.
Some local prosecutors have gone further on their own. Washtenaw County, Michigan drew national attention in 2021 when its prosecutor announced the office would no longer pursue criminal charges for consensual sex work between adults on either side of the transaction. Policies like that do not change the underlying state statute; prostitution remains technically illegal in Michigan. They change only the practical reality in that jurisdiction, and they last only as long as the official who adopted them remains in office.
Decriminalization and legalization are not the same thing. Decriminalization removes criminal penalties but creates no licensing, health inspections, or tax collection. Legalization, as in Nevada’s brothel system, builds that regulatory framework around the activity. Neither exists at the federal level.
Immigration Consequences for Non-Citizens
For non-citizens, prostitution-related conduct creates immigration problems that operate independently of the criminal case. Under 8 U.S.C. § 1182(a)(2)(D), any non-citizen who has engaged in prostitution within 10 years of applying for a visa, admission, or adjustment of status is inadmissible to the United States.12Office of the Law Revision Counsel. 8 USC 1182 – Inadmissible Aliens The same provision reaches anyone who has procured or profited from another person’s prostitution during that window.
No conviction is required. An immigration officer can find someone inadmissible based on an admission, a police report, or other evidence of prostitution activity, even if the criminal case was dismissed, diverted, or never charged. A successfully completed diversion program that avoids a criminal record does nothing to neutralize this immigration ground.
Trafficking victims have a separate pathway. Federal law authorizes T nonimmigrant status for people who are or were victims of a severe form of trafficking, are physically present in the US because of that trafficking, and cooperate with law enforcement. The T visa provides temporary legal status and a path toward permanent residence.
The IRS Still Expects Its Cut
Under 26 U.S.C. § 61, gross income includes “all income from whatever source derived,” and federal courts have consistently held that this covers earnings from illegal activity, prostitution included.13Office of the Law Revision Counsel. 26 USC 61 – Gross Income Defined Failing to report that income is tax evasion, which carries its own fines and potential prison time on top of any prostitution charges.
The reporting obligation runs into the Fifth Amendment, and the IRS has resolved the tension by not requiring taxpayers to identify the specific illegal source. You report the amount on your 1040 without labeling it as proceeds from illegal activity. Expenses that are themselves illegal cannot be deducted against this income. Ordinary expenses tied to the activity but not independently illegal, such as legal defense fees, may be deductible; the IRS applies a public-policy test to decide.
What a Conviction Costs Outside the Courtroom
The criminal sentence is often the smaller problem. A misdemeanor record for prostitution or solicitation follows a person into job applications, housing screenings, professional license reviews, and custody disputes. Many employers run background checks, and the stigma attached to this offense is heavier than it is for comparable misdemeanors. Landlords in competitive markets routinely reject applicants with such records.
Professional licensing boards in healthcare, education, law, and finance typically ask about criminal convictions and can deny or revoke a license based on a prostitution-related offense. The standards they apply, often phrased as “moral character” or “fitness to practice,” give them wide discretion, and even a low-level misdemeanor can be disqualifying.
Child custody adds another layer. Family courts weigh criminal history when evaluating a child’s best interests, and a prostitution conviction, especially paired with substance abuse allegations, can shift custody outcomes. These effects persist long after any fine is paid or sentence served.
