Age of Consent in Massachusetts: Penalties and Registration

The age of consent in Massachusetts is 16. Sexual intercourse with anyone under that age is a felony under Chapter 265, Section 23, punishable by up to life in state prison, and the law applies regardless of whether the younger person appeared willing, said they were older, or initiated the contact.¹

Massachusetts is strict compared to many other states. There is no close-in-age exception, consent from the minor is not a defense, and a defendant’s honest belief that the other person was 16 or older does not matter.

What the Statute Actually Prohibits

Section 23 is titled “rape and abuse of a child” and covers all sexual intercourse or unnatural sexual intercourse with a person under 16, whether or not force was used. To convict, the prosecution has to prove two things: that sexual intercourse occurred, and that the other person was under 16.²

The younger person’s behavior, statements about their age, or apparent maturity are legally irrelevant to guilt. They may affect sentencing, but they do not affect whether a crime occurred.

No Romeo and Juliet Exception

Many states have close-in-age laws that reduce or eliminate criminal liability when both people are teenagers close in age. Massachusetts does not. Two 15-year-olds who have sex can both technically be charged under Section 23, and the law has been applied that way.²

A 17-year-old dating a 15-year-old is committing a felony under Massachusetts law, even where the same relationship would be legal or lightly penalized in other states. This is one of the most commonly misunderstood pieces of state consent law.

Defenses That Do Not Work

Two defenses people commonly assume would apply are unavailable:

Consent of the minor. A child under 16 is legally incapable of consenting to sexual activity. Even if the minor initiated everything, consent is not a defense under Section 23.²
Mistake about the victim’s age. Massachusetts courts have held that statutory rape can be committed “with or without any knowledge on the defendant’s part of the age of the victim.” A defendant who genuinely thought the other person was of age still has no defense if they were actually under 16.²

This makes Section 23 a strict liability offense with respect to age. The prosecution does not need to show the defendant intended to have sex with someone underage or was reckless about it. The act plus the victim’s actual age is enough.

Penalties

A conviction under Section 23 carries imprisonment in state prison for life or any term of years, or a sentence in a jail or house of correction. Judges have wide discretion. A case involving a 19-year-old and a 15-year-old typically draws a very different sentence than one involving a 40-year-old and an 11-year-old, even though both are charged under the same statute.¹

One procedural detail matters: a Section 23 prosecution cannot be continued without a finding or placed on file. The case cannot be quietly shelved or resolved with a disposition that avoids a formal guilty finding. It ends in a conviction or an acquittal.¹

When a 10-Year Mandatory Minimum Applies

Section 23A imposes a mandatory minimum of 10 years in state prison when any of three aggravating factors is present:

The victim is under 12 and the defendant is more than 5 years older.
The victim is between 12 and 16 and the defendant is more than 10 years older.
The defendant is a mandated reporter (teachers, coaches, doctors, and others required to report child abuse), regardless of the age gap.

Under Section 23A, the sentence cannot be reduced below 10 years, suspended, or made subject to probation, parole, work release, or furlough until those 10 years have been served. Good-conduct credits do not apply toward the mandatory minimum.³

Sexual Conduct Short of Intercourse

Section 13B of Chapter 265 covers indecent assault and battery on a child under 14, addressing sexual touching that does not amount to intercourse. Conviction carries up to 10 years in state prison or up to two and a half years in a house of correction. A child under 14 is treated as incapable of consenting, and like Section 23, a Section 13B case cannot be continued without a finding or placed on file.⁴

Separately, Chapter 272, Section 35A criminalizes “unnatural and lascivious acts” with a child under 16, covering sexual conduct that does not involve intercourse. A first offense carries a fine of $100 to $1,000, up to five years in state prison, or up to two and a half years in a house of correction. A defendant over 18 convicted of a second offense faces a mandatory minimum of five years in state prison.

Chapter 265 also contains separate provisions for rape of a child involving force (Section 22A), rape of a child committed during other offenses (Section 22B), and enhanced penalties for repeat sex offenders (Section 23B). Each carries severe penalties and, like the other child-victim offenses, cannot be continued without a finding.

Sex Offender Registration

A conviction for statutory rape or a related offense triggers mandatory sex offender registration. Massachusetts classifies offenders into three levels based on risk of reoffending:⁵

Level 1 (low risk): information is maintained by the Sex Offender Registry Board but is not publicly available online.
Level 2 (moderate risk): the offender must register with local police, and the information is available to the public.
Level 3 (high risk): the offender must register with local police, and the information is actively disseminated to the community and published online.

Registration is not a one-time event. Offenders re-register annually, and the classification process includes a hearing where the offender can challenge the assigned level.⁶ Registered offenders routinely face difficulty finding employment and housing, and for Level 2 and Level 3 offenders the public status can follow them for decades.

No Statute of Limitations

Massachusetts has no statute of limitations for most sexual offenses against children. Charges under Section 23, Section 23A, Section 13B, and several other child-victim offenses can be brought at any point after the crime.

There is one safeguard: if charges are filed more than 27 years after the offense, the prosecution must present independent evidence corroborating the victim’s account, and that corroborating evidence cannot consist solely of opinions from mental health professionals. Any time the defendant spent living outside Massachusetts does not count toward the 27-year threshold. Someone who committed statutory rape decades ago can still face prosecution if evidence surfaces.

Federal Law Can Reach Higher Than 16

Even when Massachusetts law would allow sexual activity because the younger person is 16 or older, federal law can still apply when interstate travel is involved. Under 18 U.S.C. § 2423, knowingly transporting someone under 18 across state lines with the intent that they engage in sexual activity that violates any criminal law carries a mandatory minimum of 10 years in federal prison and a maximum of life.⁷

Federal law also prohibits traveling in interstate commerce with the intent to engage in “illicit sexual conduct” with someone under 18, carrying up to 30 years in prison. The federal threshold is 18, not the state’s age of consent. A Massachusetts resident in a legal relationship with a 17-year-old under state law could still face federal charges if interstate travel for sexual activity is involved.⁷

Marriage Is Not a Workaround

Massachusetts previously had no minimum marriage age, which created a legal gray area where marriage could theoretically affect the application of consent laws. That loophole is closed. Massachusetts became one of the first states to set the minimum marriage age at 18 with no exceptions, eliminating any argument that marriage could serve as a defense to statutory sexual conduct with a minor.
