Decriminalizing sex work in the US means repealing the state and local laws that make solicitation and commercial sex criminal offenses, so that consensual adult transactions are no longer prosecuted. That is the local piece, and several cities and a handful of states have taken partial steps toward it. The harder piece is federal: a set of statutes on trafficking, interstate travel, money laundering, and immigration continues to apply regardless of what any state does, which is why no U.S. jurisdiction has yet achieved the kind of full decriminalization seen in New Zealand.
What Decriminalization Actually Means
Decriminalization removes sex work from the criminal code. Police lose the authority to arrest for it, and courts cannot impose criminal penalties. Whatever civil and labor law already governs any workplace is what remains.
This is different from legalization, which brings the industry under a dedicated regulatory system: mandatory registration, health screenings, licensed premises, designated zones. Step outside those terms under legalization and the conduct is criminal again. Decriminalization skips that apparatus entirely.
It is also different from the Nordic or Equality Model, which Sweden introduced on January 1, 1999. That approach decriminalizes the sale of sex but keeps the purchase criminal, along with third-party involvement.1Office of Justice Programs. Evaluation of the Swedish Legislation Criminalising the Purchase of Sexual Services Sellers avoid arrest, but the market itself remains illegal, which affects how workers can screen clients or report violence. When people ask about decriminalizing sex work, they sometimes mean this partial model and sometimes mean full decriminalization. The two produce very different day-to-day realities.
Full decriminalization removes criminal penalties for everyone in a consensual adult transaction: seller, buyer, and business operator. New Zealand’s Prostitution Reform Act of 2003 is the standard reference point. Contracts for commercial sexual services are legally enforceable there, ordinary workplace health and safety law applies, and workers have a statutory right to refuse any client or practice.2The Warnath Group. Prostitution Reform Act 2003 Nothing structurally comparable exists in the United States.
Federal Statutes That Keep Applying
Even in a state or city that stops enforcing prostitution laws, a separate layer of federal criminal law stays in force. This is the piece most decriminalization conversations underestimate.
FOSTA-SESTA and Online Platforms
The Allow States and Victims to Fight Online Sex Trafficking Act, passed in 2018, amended Section 230 of the Communications Decency Act to strip platform immunity in this area. The operative statute is 18 U.S.C. § 2421A. Owning or operating an online platform with the intent to facilitate the prostitution of another person carries up to 10 years in prison. If the conduct involves five or more people, or if the operator acts with reckless disregard that the platform contributed to sex trafficking, the maximum rises to 25 years.3Office of the Law Revision Counsel. 18 USC 2421A – Promotion or Facilitation of Prostitution and Reckless Disregard of Sex Trafficking
After the law passed, platforms that workers had used to screen clients, describe services, and set terms in advance either shut down or restricted content heavily. Affected communities reported losing the ability to vet clients before meeting, and a shift toward less safe working conditions. The statute applies whether or not local authorities prosecute the underlying activity.
The Mann Act
18 U.S.C. § 2421 makes it a federal crime to knowingly transport any person across state lines with the intent that they engage in prostitution, punishable by up to 10 years in prison.4Office of the Law Revision Counsel. 18 USC 2421 – Transportation Generally The statute dates to 1910 and sweeps broadly. A worker who travels between states, or anyone who arranges that travel, can face federal charges even if neither state prosecutes the work itself.
The Travel Act
18 U.S.C. § 1952 targets anyone who uses interstate commerce or the mail to promote or facilitate “unlawful activity,” which the statute defines to include prostitution offenses under state or federal law. Violations carry up to five years in prison.5Office of the Law Revision Counsel. 18 USC 1952 – Interstate and Foreign Travel or Transportation in Aid of Racketeering Enterprises Because the definition of unlawful activity points back to state law, the statute can reach conduct connected to any state that still criminalizes sex work, even when the person is located in one that does not.
Money Laundering and Asset Forfeiture
The federal exposure extends to money. Under 18 U.S.C. § 1956, conducting a financial transaction involving proceeds of “specified unlawful activity” with the intent to promote it or conceal the source is money laundering.6Office of the Law Revision Counsel. 18 USC 1956 – Laundering of Monetary Instruments Travel Act violations involving prostitution qualify.
Civil forfeiture is the practical consequence. 18 U.S.C. § 981 lets the federal government seize property traceable to proceeds of specified unlawful activity, and “proceeds” is defined broadly to cover gross revenue rather than net profits.7Office of the Law Revision Counsel. 18 USC 981 – Civil Forfeiture Vehicles, electronics, cash, and real property used in connection with the activity can all be seized, and the government can bring a civil forfeiture case without any criminal conviction.
Immigration Consequences for Noncitizens
For anyone who is not a U.S. citizen, this is often the most consequential piece, and it does not depend on a conviction. Under 8 U.S.C. § 1182(a)(2)(D), a noncitizen who has engaged in prostitution within 10 years of applying for a visa, admission, or adjustment of status is inadmissible.8Office of the Law Revision Counsel. 8 USC 1182 – Inadmissible Aliens The same provision covers anyone who directly or indirectly procures prostitution or has received proceeds from it within that 10-year window. A separate clause reaches noncitizens coming to the United States to engage in any unlawful commercialized vice.
The engagement itself is what triggers inadmissibility. There is no requirement of arrest, charge, or conviction. Local decriminalization does not override this. A person can work lawfully under a city’s non-prosecution policy and still create a bar to future immigration benefits through the same activity.
Tax and Banking Realities
The IRS treats income as income regardless of its legal status. Earnings from sex work must be reported, and in a decriminalized setting this is generally done on Schedule C as self-employment income, with self-employment tax owed alongside income tax. Where the underlying work remains illegal under state law, workers often avoid filing because the paper trail can be used in other proceedings, but the tax obligation itself does not disappear.
Banking is a persistent problem even where local law has changed. Financial institutions routinely close accounts or decline applications tied to the sex industry, citing anti-money laundering compliance. A joint statement from FinCEN, the Federal Reserve, the FDIC, the OCC, and the NCUA has clarified that no rule requires terminating a customer relationship based solely on industry, and that customers of a particular type do not automatically pose uniformly higher risk. The practice of “de-risking” whole categories of customers continues anyway. Basic checking accounts, card processing, and business insurance remain difficult to obtain.
How Far U.S. Reform Has Actually Gone
No U.S. state has fully decriminalized sex work. What exists instead is a mix of prosecutorial discretion at the local level and narrower legislative measures at the state level.
Several district attorneys have adopted non-prosecution policies. Manhattan’s district attorney moved to dismiss more than 900 pending prostitution cases, some decades old, and instructed the office’s Human Trafficking Response Unit to decline prosecution going forward. Baltimore’s former state’s attorney announced in 2020 that the city would stop prosecuting prostitution as part of a public health approach. Brooklyn and other jurisdictions have taken similar steps.
These policies matter, but they are fragile. A successor prosecutor can reverse them. The state statutes remain on the books, so police can still arrest even when charges will be declined, and the arrest itself carries consequences: a booking record, potential job loss, and immigration exposure. Some offices have paired non-prosecution with motions to vacate old convictions, which addresses the lasting barriers a prostitution record creates for housing, employment, and immigration eligibility.
At the state legislative level, 2025 saw a record number of decriminalization-related bills, though most targeted limited immunity rather than full repeal. Hawaii and Rhode Island enacted laws granting immunity to sex workers who report crimes or seek medical help, without extending protections to clients. New York’s legislature passed an immunity bill. Nevada passed a similar safe harbor measure that the governor vetoed. Broader bills that would remove criminal liability for all parties in consensual adult transactions remain pending in states including Massachusetts. The direction of travel is toward incremental safe-harbor protections rather than removing sex work from the criminal code.
The federal layer is the ceiling on how far any of this can go. A state cannot override 18 U.S.C. § 2421A, the Mann Act, or the Travel Act. Because the Travel Act defines unlawful activity by reference to state law, interstate activity can still trigger federal prosecution as long as sex work remains illegal in any state connected to the transaction. Decriminalizing sex work in the US in the full sense would require either federal action or a state-by-state effort thorough enough to eliminate the state-law predicates the federal statutes rely on.
