Pennsylvania Age of Consent: Close-in-Age Rule and Penalties

The age of consent in Pennsylvania is 16. Sexual intercourse with someone younger becomes a crime once the older person is at least four years older, and the charge grows more serious as that gap widens. The threshold effectively rises to 18 when the older person is a teacher, coach, guard, or anyone else in a position of authority over the minor, and separate rules apply when the younger person is under 13.

How the 16 Threshold Is Set

No Pennsylvania statute announces “the age of consent is 16” in those words. The number comes out of 18 Pa.C.S. § 3122.1, the statutory sexual assault law, which criminalizes intercourse with a complainant “under the age of 16” when the older party exceeds specified age gaps. Because the offense only reaches conduct involving someone under 16, a 16- or 17-year-old is treated as legally capable of consenting to sex with a partner of any age, subject to the authority-figure and corruption-of-minors rules discussed below.¹

The statute grades the offense by how far apart the two people are in age:

Four to seven years older than a complainant under 16: felony of the second degree.
Eight to ten years older: also a second-degree felony, under a separate subsection that carries different registration consequences.
Eleven or more years older: felony of the first degree.

All three provisions require that the parties are not married to each other. Marriage to the complainant takes the conduct outside the statute.¹

The Close-in-Age Rule

When the older person is less than four years older, § 3122.1 does not apply at all. A 17-year-old with a 15-year-old, for example, falls outside the statute because the gap is under four years. People sometimes call this a “Romeo and Juliet” exemption, though that phrase appears nowhere in Pennsylvania’s criminal code. The practical effect is that teenagers close in age are not prosecuted under the statutory sexual assault law for consensual activity.¹

The four-year threshold runs through the rest of Pennsylvania’s sexual offense chapter as well. Involuntary deviate sexual intercourse, aggravated indecent assault, and indecent assault each include age-based provisions that only engage when the older party is four or more years older than a complainant under 16.²³

The close-in-age rule is not a blanket shield. If the younger person is under 13, the age gap is irrelevant. Rape of a child under 13 is a first-degree felony no matter how old the other person is.⁴

When the Age Effectively Rises to 18

Two other statutes make sex with a 16- or 17-year-old a crime in circumstances where the older person holds authority over the minor or is themselves an adult.

Institutional Sexual Assault

Under 18 Pa.C.S. § 3124.2, employees and agents of certain institutions face charges for sexual contact with a minor in their institution’s care, even when the minor is 16 or 17. The statute reaches correctional facilities, youth development centers, juvenile detention centers, licensed residential programs for children, and mental health institutions, and covers inmates, detainees, patients, and residents under 18.⁵

Schools have their own subsection. Any employee, volunteer, or person with direct contact with students who has sexual intercourse or indecent contact with a student commits a third-degree felony. Child care centers are covered by a parallel provision. Peace officers are also covered when the other person is in their custody or is serving as a confidential informant.⁵

The result: a 17-year-old student can legally consent to sex with an unrelated 25-year-old, but not with a teacher, coach, or guard.

Corruption of Minors

Pennsylvania’s corruption of minors statute, 18 Pa.C.S. § 6301, applies to anyone 18 or older whose conduct corrupts or tends to corrupt the morals of a minor under 18. It is ordinarily a first-degree misdemeanor, but when the conduct involves an offense under Chapter 31 (the sexual offenses chapter), it becomes a third-degree felony.⁶

This is the provision that reaches conduct § 3122.1 does not. A 20-year-old having sex with a 16-year-old cannot be charged with statutory sexual assault because the complainant is 16. Prosecutors can still bring a corruption of minors charge on the theory that the conduct tends to corrupt the minor’s morals. Whether they do varies by county and circumstance, but the exposure is real. A reasonable-mistake-of-age defense is available when the minor is 16 or 17, but disappears entirely when the minor is under 16.⁶

Children Under 13

Pennsylvania treats sexual contact with a child under 13 as its most serious category of sex crime. No age gap, no perceived consent, and no mistake-of-age argument matters.

Rape of a child occurs when anyone has sexual intercourse with a complainant under 13, and is a first-degree felony. When the child suffers serious bodily injury, an enhanced first-degree offense applies with greater sentencing exposure.⁴ Involuntary deviate sexual intercourse with a child under 13 is also a first-degree felony, but carries a maximum of 40 years rather than the ordinary 20-year cap.⁷

Aggravated indecent assault involving a child under 13 is a second-degree felony by default and can be charged as a first-degree felony where forcible-compulsion provisions also apply.² Indecent assault with a child under 13 is a first-degree misdemeanor that can escalate to a third-degree felony for repeat conduct or when intimate parts are involved.³

What a Conviction Carries

Maximum prison terms in Pennsylvania are set by 18 Pa.C.S. § 1103. A first-degree felony carries up to 20 years, a second-degree felony up to 10 years, and a third-degree felony up to 7 years. The 40-year maximum for involuntary deviate sexual intercourse with a child under 13 is a specific exception. The maximum fine is $25,000 for both first- and second-degree felonies.⁸⁹

A concrete example: a 25-year-old convicted of statutory sexual assault involving a 14-year-old faces a second-degree felony because the gap is at least 8 years but less than 11. Push the older person to 28 with the same complainant, and the gap crosses 11 years, making it a first-degree felony with double the prison exposure.¹

Sex Offender Registration

A conviction for a sexual offense involving a minor triggers mandatory registration under Pennsylvania’s Sex Offender Registration and Notification Act, in Title 42 of the Pennsylvania Consolidated Statutes. The state uses three tiers: Tier I requires 15 years of registration, Tier II requires 25 years, and Tier III is lifetime.¹⁰

Statutory sexual assault falls into different tiers depending on the subsection. A conviction under § 3122.1(a)(2), covering an 8-to-10-year gap, is a Tier II offense with 25 years of registration. A conviction under § 3122.1(b), covering an 11-plus-year gap, is Tier III with lifetime registration.¹⁰¹¹ Registration information goes to the Pennsylvania State Police and becomes publicly accessible. Failing to comply is a separate crime.

Federal Consequences

Registration has federal follow-on effects. A registered sex offender must notify the registration jurisdiction at least 21 days before any international travel; leaving the country without doing so is a federal crime carrying up to 10 years.¹²¹³ Under the International Megan’s Law, the State Department also stamps a visual identifier on the passport of anyone currently required to register, and many countries refuse entry on the strength of it.¹⁴

Anyone subject to lifetime registration is permanently barred from federally assisted housing, including public housing and Section 8 vouchers.¹⁵ Registration status also appears on background checks and can be considered by employers, particularly in education, healthcare, child care, and government roles.
