Prostitution laws by country fall into four broad models: total prohibition, full decriminalization, legalized regulation, and buyer-only criminalization. The same transaction that triggers a prison sentence in one jurisdiction generates licensed business tax revenue in another, and several countries split authority among states or provinces so the rules change at an internal border. Beyond the criminal statute itself, prostitution-related activity carries immigration, tax, and digital-platform consequences that reach well past the country where the conduct occurred.
Total Prohibition
Under total prohibition every side of the transaction is criminal: selling, buying, running a brothel, and facilitating the exchange. Most of the Middle East and large parts of Africa follow this model, with enforcement grounded in religious or moral codes and penalties ranging from fines and jail time to far harsher consequences for repeat offenders or organizers.
Most U.S. states also prohibit all sides of the transaction through their penal codes. A first offense is typically a misdemeanor; repeated convictions can be elevated to a felony. The notable exception is Nevada, where licensed brothels are legal in counties with fewer than 700,000 residents. Ten of Nevada’s sixteen counties currently permit licensed operations, but the two counties containing Las Vegas and Reno do not, and prostitution outside a licensed brothel remains illegal statewide.
The theory behind prohibition is that criminalizing every participant will shrink the market. In practice, enforcement tends to fall most heavily on sellers and street-level activity rather than on buyers or organizers.
Full Decriminalization
Full decriminalization removes criminal penalties specific to sex work and lets the industry operate under the same employment, health, and business laws that cover any other occupation. New Zealand is the leading example through its Prostitution Reform Act of 2003, which replaced prior criminal sanctions with a framework built around human rights, occupational safety, and public health.
Under the New Zealand model, sex workers have a statutory right to refuse any particular client or sexual practice, and consent can be withdrawn at any point during a transaction. Workers can use the same employment dispute resolution processes available in any other field, and refusing sex work does not affect eligibility for social benefits. Brothel operators must hold an operator certificate issued by a District Court registrar, applicants can be disqualified based on serious criminal convictions, and certificates are renewed annually. Oversight sits with labor inspectors and public health officials rather than police.
UNAIDS has estimated that decriminalization could avert 33 to 46 percent of HIV infections among sex workers and their clients over a ten-year period, primarily because criminal environments discourage condom use and limit access to health services.1UNAIDS. HIV and Sex Work – Human Rights Fact Sheet Series 2024
Legalization With Government Licensing
Legalization differs from decriminalization in a meaningful way: sex work is permitted, but only through active participation in government licensing, registration, and oversight. Operating outside that system remains criminal. Germany and the Netherlands are the clearest examples.
Germany
Germany’s Prostitutes Protection Act (Prostituiertenschutzgesetz), in force since July 2017, requires every person providing sexual services to register personally with local authorities before beginning work.2Federal Ministry for Family Affairs, Senior Citizens, Women and Youth. The New Prostitute Protection Act Registered workers must attend a health consultation annually, or every six months for those under 21. These sessions cover available health services, social legislation, and counseling resources rather than clinical screenings. The law mandates condom use during all paid sexual services.
Brothel operators need specialized permits involving background checks, building inspections, and compliance with operational rules. Violations such as operating without a permit or failing to register can result in significant fines, and the state can revoke business licenses for noncompliance. Taxes are collected on earnings the same way they would be in any other regulated industry.
The Netherlands
The Netherlands treats sex work as a legal profession, but municipalities control the licensing. Each city decides whether to issue operating permits and sets its own conditions, including where a sex business may be located.3Business.gov.nl. Working as an Operator in the Sex Industry Operators must be at least 21, register with the Netherlands Chamber of Commerce, and often submit a business plan covering hygiene, worker independence, anti-trafficking measures, safety, and working conditions.
Operators and workers pay income tax and submit VAT returns like any other business.4Government of the Netherlands. Salaries Tax and Social Insurance Contributions Forcing a sex worker into prostitution is a criminal offense, and clients who knowingly use services provided under coercion also face prosecution.3Business.gov.nl.

Criminalization of Buyers (the Nordic Model)
The Nordic model, sometimes called the abolitionist approach, flips traditional enforcement. The buyer commits a crime; the seller does not. The reasoning is that demand drives the market, so penalizing buyers should shrink the industry without further marginalizing people who sell sex.
Sweden
Sweden pioneered this approach when its Sex Purchase Act took effect on January 1, 1999, as part of the Kvinnofrid (Women’s Peace) legislation. The prohibition was later incorporated into Chapter 6, Section 11 of the Swedish Penal Code. Paying for a sexual service carries a fine or imprisonment of up to one year.5Government Offices of Sweden. 11.4 Purchase of Sexual Services The law reaches both the person who pays directly and anyone who takes advantage of a sexual service paid for by someone else.6Legal Information Institute. Brottsbalk (Criminal Code)
Canada
Canada adopted a similar framework through the Protection of Communities and Exploited Persons Act, which for the first time in Canadian criminal law created an offense specifically for purchasing sexual services or communicating for that purpose.7Department of Justice. Prostitution Criminal Law Reform – Bill C-36, the Protection of Communities and Exploited Persons Act Because the purchase is criminal every time a transaction occurs, prostitution is effectively illegal from the buyer’s side while the seller is not prosecuted for selling.8Justice Laws Website. Protection of Communities and Exploited Persons Act
France and Norway
France banned the purchase of sex in 2016 while keeping the sale legal. A first offense carries a €1,500 fine, rising to €3,750 for a repeat conviction, and convicted buyers must complete a mandatory awareness course on the harms of the sex trade. Norway followed a similar path in 2009, with fines for buyers typically running between 15,000 and 25,000 Norwegian kroner (roughly $1,400 to $2,400 USD).
Sellers in these countries are not prosecuted for selling, but anti-brothel and anti-pimping provisions that remain on the books often prevent them from sharing indoor spaces, advertising, or hiring security. Research across Sweden, Norway, and Finland has found that support services tend to focus on exit counseling rather than health or legal assistance.
Countries With Internal Patchworks
Some countries leave sex work regulation to state, provincial, or municipal governments, producing systems where an activity that is legal on one side of a border becomes criminal on the other.
Australia is the most visible example. New South Wales decriminalized street-based sex work in 1979 and legalized brothels in 1995, making it one of the earliest jurisdictions to adopt full decriminalization. Queensland and Victoria have also moved toward decriminalization. South Australia keeps brothels and public solicitation illegal, though the act of selling sex itself is not criminalized there, and several reform efforts in that state have failed since the late 1970s.
Mexico has no federal legislation addressing sex work at all. Each state and municipality sets its own rules through local health, public order, and zoning regulations. Some municipalities operate tolerance zones with health requirements; others prohibit the activity outright. A person’s legal rights change the moment they cross a municipal line.
U.S. Federal Law on Top of State Rules
Even where a U.S. state permits some form of sex work, federal statutes create separate criminal exposure that is easy to overlook.
The Mann Act (18 U.S.C. § 2421) makes it a federal crime to knowingly transport someone across state lines or international borders with the intent that they engage in prostitution. The penalty is up to 10 years in prison, a fine, or both.9Office of the Law Revision Counsel. 18 USC 2421 – Transportation Generally The statute has been in force since 1910 and remains actively prosecuted, particularly in trafficking investigations.
In 2018, the FOSTA-SESTA legislation (codified at 18 U.S.C. § 2421A) created a new federal crime targeting website operators. Anyone who owns, manages, or operates an online platform with the intent to promote or facilitate prostitution faces up to 10 years in prison. If the platform facilitates five or more people or acts in reckless disregard of sex trafficking, the maximum rises to 25 years.10Office of the Law Revision Counsel. 18 USC 2421A – Promotion or Facilitation of Prostitution and Reckless Disregard of Sex Trafficking The law also stripped Section 230 immunity from platforms that knowingly host prostitution-related content, which led to the rapid shutdown of several well-known advertising sites.
On the tax side, the IRS requires taxpayers to report income from illegal activities, including prostitution, on their federal return. Publication 525 states that such income must be reported on Schedule 1 or Schedule C.11IRS. Publication 525 (2025), Taxable and Nontaxable Income Failing to report it creates tax-evasion exposure on top of any state criminal charges.
Immigration Consequences That Cross Borders
Prostitution-related activity carries immigration consequences that extend well past any criminal sentence. Under U.S. immigration law, anyone who has engaged in prostitution within the 10 years preceding a visa application, admission, or adjustment of status is inadmissible. The same 10-year bar applies to anyone who has procured others for prostitution or received proceeds from it.12Office of the Law Revision Counsel. 8 USC 1182 – Inadmissible Aliens
This provision triggers even when the conduct was legal where it occurred. A person who worked lawfully in a licensed German brothel or a New Zealand-certified business can still be barred from entering the United States for a decade. Owning, managing, or supervising a prostitution business can be classified as an aggravated felony for immigration purposes, which carries deportation and permanent bars on reentry. Applicants with prior prostitution-related activity who seek U.S. permanent residency typically need a formal waiver of inadmissibility, and approval is not guaranteed.
Public Health and the Policy Debate
International health bodies have taken a clear position in the debate over which model best protects public health. UNAIDS has called for ending the criminalization of all aspects of sex work on the grounds that criminalization increases HIV risk and limits access to prevention and treatment.1UNAIDS. HIV and Sex Work – Human Rights Fact Sheet Series 2024 The World Health Organization’s consolidated guidelines for key populations align with this view.
A cross-country analysis cited by UNAIDS found that sex workers in countries that criminalize the trade were over seven times more likely to be living with HIV than those in countries with partial legalization.1UNAIDS. HIV and Sex Work – Human Rights Fact Sheet Series 2024 One commonly cited mechanism is police use of condom possession as evidence of prostitution, which discourages workers from carrying them. UNAIDS has also noted that criminalizing only buyers under the Nordic model produces negative outcomes for sellers, including reduced condom use and increased violence. Countries that maintain prohibition or buyer-only criminalization generally counter that decriminalization normalizes exploitation and raises trafficking risk, and the two camps show little sign of converging.
