Few charges carry the weight — legally and personally — that allegations of rape in Massachusetts do. The law isn’t a single statute. It’s a layered structure of offenses, each with its own sentencing rules, mandatory minimums, and procedural restrictions. If you’ve been charged, understanding exactly which statute applies to your case isn’t an abstract legal exercise. It directly determines how much prison time you could face, whether a judge has any flexibility in sentencing, and what happens to your life after any sentence ends.
This guide breaks down each charge plainly.
Non-Aggravated Rape — G.L. c. 265, § 22(b)
This is the base rape charge under Massachusetts law: sexual intercourse or unnatural sexual intercourse by force and against a person’s will, without additional aggravating factors.
Maximum penalty: up to 20 years in state prison.
A second or subsequent conviction under this section carries life in state prison or any term of years. While § 22(b) carries less exposure than the aggravated versions, it is still a felony that triggers mandatory sex offender registration. There is no minimum sentence on a first offense, which means judicial discretion plays a significant role in the outcome.
Aggravated Rape — G.L. c. 265, § 22(a)
Aggravated rape applies when certain circumstances accompany the rape itself — most commonly, serious bodily injury to the victim, that the rape was committed during a kidnapping, or that it was committed jointly with another person.
Penalty: up to life in state prison.
Rape While Armed — G.L. c. 265, § 22
If any rape offense under § 22 — aggravated or non-aggravated — is committed while the defendant is armed with a firearm, rifle, shotgun, machine gun, or assault weapon, a mandatory minimum applies regardless of other circumstances.
Mandatory minimum: 10 years in state prison.
The sentence cannot be reduced below 10 years, suspended, or placed on probation. For a second or subsequent offense involving a weapon, that floor rises to 15 years. Defendants serving those repeat-offense sentences are not eligible for furlough or any release program until having served at least two-thirds of the mandatory minimum.
Forcible Rape of a Child — G.L. c. 265, § 22A
Section 22A covers sexual intercourse or unnatural sexual intercourse with a child under 16, where the child is compelled to submit by force or by threat of bodily injury. Unlike statutory rape (§ 23), this charge requires proof of force or a physical threat.
Penalty: up to life in state prison.
For a defendant over 18 convicted of a second or subsequent offense, there is a mandatory minimum of five years.
A prosecution under § 22A cannot be continued without a finding (CWOF) and cannot be placed on file. A judge has no authority to grant a CWOF on this charge.
Aggravated Rape of a Child With Force — G.L. c. 265, § 22B
Section 22B takes the § 22A framework and adds aggravating factors that trigger a mandatory minimum sentence. The charge applies when the forcible rape of a child under 16 is accompanied by one or more of the following:
- Committed during the commission of another serious offense (armed robbery, kidnapping, burglary, home invasion, assault with a dangerous weapon, among others)
- Committed by means of substantial bodily injury to the victim
- Committed while the victim was tied, bound, or gagged
- Committed after the defendant administered alcohol or a controlled substance to the victim without consent
- Committed jointly with others (joint enterprise)
- Committed in a way that could expose the victim to a sexually transmitted disease the defendant knew or should have known they carried
Mandatory minimum: 15 years in state prison.
The sentence cannot be reduced below 15 years, suspended, or placed on probation. No parole, work release, furlough, or good conduct credit applies until the full 15 years are served. As with § 22A, prosecutions under § 22B cannot be continued without a finding and cannot be placed on file.
Statutory Rape — G.L. c. 265, § 23
Section 23 — commonly called statutory rape — covers sexual intercourse or unnatural sexual intercourse with a person under 16. Force is not an element. Consent is not a defense. The Commonwealth does not need to prove the defendant knew the alleged victim’s age, and a genuine, reasonable belief that the person was 16 or older is not a defense under Massachusetts law.
Massachusetts has no “Romeo and Juliet” exception. A 19-year-old and a 15-year-old in a relationship both considered consensual can result in a charge carrying life imprisonment exposure.
Penalty: up to life in state prison, or any term in a house of correction.
A prosecution under § 23 cannot be continued without a finding and cannot be placed on file. Conviction triggers mandatory sex offender registration. The Sex Offender Registry Board (SORB) assigns a classification of Level 1, 2, or 3 based on an individualized assessment of 38 regulatory factors. Even at Level 1 — the lowest classification — registration is required for a minimum of 10 years.
Aggravated Statutory Rape — G.L. c. 265, § 23A
Section 23A elevates statutory rape to an aggravated offense when any of the following are present:
- The defendant is more than 5 years older than the victim, and the victim is under 12
- The defendant is more than 10 years older than the victim, and the victim is between 12 and 16
- The defendant was a mandated reporter (teacher, doctor, nurse, social worker, or other person legally required to report child abuse) at the time of the offense
Mandatory minimum: 10 years in state prison.
The 10-year minimum cannot be reduced, suspended, or subject to probation or parole. The defendant is not eligible for work release, furlough, or good conduct deductions until that minimum is fully served. Prosecutions under § 23A, like § 23, cannot be continued without a finding.
Indecent Assault and Battery — G.L. c. 265, §§ 13B and 13H
Not every sex crime charge involves intercourse. Indecent assault and battery covers intentional, unconsented touching of a sexual nature — touching a person’s genitals, buttocks, or breasts, or other contact that is “fundamentally offensive to contemporary moral values.” There is no exhaustive list; courts assess the conduct on a case-by-case basis.
The penalty depends on the victim’s age:
On a child under 14 — § 13B
Up to 10 years in state prison, or up to 2½ years in a house of correction. A second or subsequent offense carries life in state prison or any term of years. Prosecution under § 13B cannot be continued without a finding and cannot be placed on file. A child under 14 is deemed legally incapable of consenting, so consent is not a defense. Conviction triggers mandatory sex offender registration.
On a person 14 or older — § 13H
Up to 5 years in state prison, or up to 2½ years in a house of correction. If the victim is an elder or person with a disability, the maximum rises to 10 years, and a second or subsequent such offense carries up to 20 years. A CWOF is prohibited on those elder/disability cases.
One important distinction: § 13B is a lesser included offense of § 22A (forcible rape of a child). It is not uncommon for the Commonwealth to charge both, or for a § 22A charge to be resolved as a § 13B. That resolution — while still serious — carries a lower sentencing ceiling than a rape conviction.
What These Charges Share
Every conviction under the statutes above requires sex offender registration under G.L. c. 6, § 178C (with limited judicial discretion for § 13H where the victim is over 14). Registration follows a person after their sentence ends and affects housing, employment, and in higher classifications, community notification. The criminal sentence is only one part of the picture.
The no-CWOF restrictions across §§ 13B, 22A, 22B, 23, and 23A are equally significant. In many areas of Massachusetts criminal law, a CWOF is a common resolution — it avoids a formal conviction while closing the case. For these charges, that option does not exist. Any finding of guilt must be a guilty finding.
Facing These Charges? The Details Matter.
Sex crime cases turn on specifics — the exact language of the allegations, the credibility of witnesses, the forensic evidence, the electronic records, and inconsistencies across prior statements. These cases demand attorneys who understand this area of law in depth: which motions to file, which evidence to challenge, what the Commonwealth actually needs to prove, and when a plea makes sense versus when a case should go to trial.
