Prostitution is partially legal in Maine. Since 2023, selling sex is no longer a crime under state law, but buying sex, promoting prostitution, and sex trafficking all remain illegal and carry penalties that range from a few months in jail to decades in prison. Federal law adds more risk when the activity crosses state lines or moves online, and immigration consequences can attach even without a conviction.
What Changed in 2023
Maine repealed Title 17-A, Section 853-A, the statute that had made it a crime for a person to engage in prostitution.1Maine Legislature. Maine Code Title 17-A 853-A – Engaging in Prostitution Before that repeal, both sides of the transaction could be charged. Now, only the buyer faces criminal liability under state law.
The repeal did not legalize prostitution more broadly. Running a prostitution operation, paying for sex, and trafficking people into the sex trade all remain crimes. What changed is that a person selling sex can now approach law enforcement, seek services, or report violence without being charged for the underlying conduct. People with old convictions for selling sex may also seek to have those convictions vacated, which can matter for employment, housing, and immigration proceedings.
Buying Sex Is Still a Crime
Under Title 17-A, Section 853-B, paying or agreeing to pay for a sexual act is a Class E crime — up to six months in jail and a $1,000 fine. The sex act does not have to happen; the offer plus something of value is enough.2Maine State Legislature. Maine Code Title 17-A 853-B – Engaging Person for Prostitution3Maine State Legislature. Maine Code Title 17-A 1604 – Imprisonment for Crimes Other Than Murder4Maine State Legislature. Maine Code Title 17-A 1704 – Maximum Fine Amounts Authorized for Convicted Individuals
A second or later conviction within two years is a Class D crime, punishable by up to 364 days in jail and a $2,000 fine.2Maine State Legislature. Maine Code Title 17-A 853-B – Engaging Person for Prostitution The two-year window matters: a prior conviction older than two years does not trigger the upgrade.
Buying Sex From a Minor
Title 17-A, Section 855 treats buyers of minors more harshly and splits the offense into two tiers based on knowledge. If the buyer does not know the other person is under 18, it is a Class D crime — up to 364 days in jail and a $2,000 fine.5Justia Law. Maine Code Title 17-A 855 – Patronizing Prostitution of Minor If the buyer knows the person is under 18, it becomes a Class C crime — up to five years in prison and a $5,000 fine.4Maine State Legislature. Maine Code Title 17-A 1704 – Maximum Fine Amounts Authorized for Convicted Individuals
Prosecutors do not have to show that the buyer checked ID. The setting, the minor’s appearance, and prior communications can all support a finding that the buyer knew.
Promoting Prostitution and Sex Trafficking
Title 17-A, Section 853 covers sex trafficking in the sense of promoting prostitution. The definition is broad: recruiting people into prostitution, running a location where it occurs, transporting someone within the state for that purpose, or taking a share of the proceeds all qualify.6Maine Legislature. Maine Code Title 17-A 851 – Definitions A first offense is a Class D crime.7Maine State Legislature. Maine Revised Statutes Title 17-A Chapter 35 – Sex Trafficking, Prostitution and Public Indecency
With two or more prior convictions for sex trafficking or related offenses, the charge upgrades to a Class C crime, carrying up to five years in prison and a $5,000 fine.7Maine State Legislature. Maine Revised Statutes Title 17-A Chapter 35 – Sex Trafficking, Prostitution and Public Indecency
Aggravated Sex Trafficking
Title 17-A, Section 852 covers the most serious conduct. Compelling someone into prostitution through force, threats, drugs, or deception is aggravated sex trafficking, as is promoting the prostitution of a minor aged 15 to 17 or a person with a mental disability. These are Class B crimes, punishable by up to 10 years in prison and $20,000 in fines.8Maine Legislature. Maine Code Title 17-A 852 – Aggravated Sex Trafficking4Maine State Legislature. Maine Code Title 17-A 1704 – Maximum Fine Amounts Authorized for Convicted Individuals
The statute defines “compelling” broadly. It includes drugging someone, withholding substances from a person who is dependent, making false promises, taking passports or immigration documents, using debt bondage, and threatening to report someone to immigration authorities.8Maine Legislature. Maine Code Title 17-A 852 – Aggravated Sex Trafficking
Trafficking a child aged 14 or younger is the most severely punished offense in this chapter. It is a Class A crime, with fines up to $50,000 and the longest available prison term under Maine law.8Maine Legislature. Maine Code Title 17-A 852 – Aggravated Sex Trafficking9Maine Legislature.

Courts can also impose probation, restitution, counseling, or community service. Judges retain discretion to order alternative sentencing for lower-level offenses, particularly first-time buyers, but a conviction still creates a criminal record.3Maine State Legislature.

Federal Charges Are Separate
State lines change the picture. Under the Mann Act, 18 U.S.C. § 2421, knowingly transporting a person across state lines or international borders with the intent that they engage in prostitution is a federal crime punishable by up to 10 years in prison. Federal prosecutors do not need to prove that prostitution actually occurred; transportation plus intent is enough.10Office of the Law Revision Counsel. 18 U.S. Code 2421 – Transportation Generally
Online activity creates a second federal exposure. Under 18 U.S.C. § 2421A, operating a website or online platform with intent to promote or facilitate prostitution carries up to 10 years in federal prison. If the platform facilitates prostitution involving five or more people, or if the operator acts in reckless disregard of sex trafficking, the maximum rises to 25 years, and courts must order restitution in trafficking-related cases.11Office of the Law Revision Counsel. 18 U.S. Code 2421A – Promotion or Facilitation of Prostitution and Reckless Disregard of Sex Trafficking
Someone arranging paid sex through an app or website while traveling through Maine can face state and federal charges at the same time.
Immigration Consequences Still Apply
For non-citizens, a prostitution-related arrest can have consequences far worse than the criminal penalties. Under federal immigration law, a person who has engaged in prostitution within the past 10 years is inadmissible to the United States, as is a person who procured prostitutes or received the proceeds of prostitution.12Office of the Law Revision Counsel. 8 U.S. Code 1182 – Inadmissible Aliens
Several details catch people off guard. Inadmissibility for engaging in prostitution does not require a conviction; immigration authorities can rely on arrest records, police reports, or admissions during an interview. The 10-year clock runs from the date of the visa or green card application, not from the date of the conduct. And Maine’s 2023 decriminalization only removes state criminal liability. The same conduct can still trigger federal immigration consequences, because state and federal systems operate independently.
Offenses involving the management or operation of a prostitution business can be treated as aggravated felonies for immigration purposes, which cuts off nearly all forms of relief from deportation. Waivers are sometimes available, but they are difficult to obtain.
How Enforcement Actually Works
With selling sex no longer a crime, Maine enforcement now focuses on the demand side. Undercover stings are the primary tool: officers pose as sex workers online or in known areas, and an agreement to pay for sex, even by text message, provides enough evidence for arrest.
State agencies work with the FBI and Homeland Security Investigations on cases involving trafficking networks or interstate activity. Those joint operations tend to produce the heaviest charges, since federal prosecutors can layer Mann Act violations on top of state offenses.
Some Maine courts offer diversion programs for first-time buyers, with education courses, counseling, or community service in exchange for reduced or dismissed charges. Availability is limited. For people who were previously convicted of selling sex, the 2023 law change opens the door to vacating those convictions, which can matter for jobs, housing, and immigration.
