Statutory Rape in PA: Laws, Penalties, and Age Exceptions

In Pennsylvania, what people commonly call statutory rape is prosecuted under a law titled statutory sexual assault, 18 Pa.C.S. § 3122.1. It makes sexual intercourse with someone under 16 a felony whenever the other person is at least four years older, regardless of consent. How serious the felony gets, and how long a conviction follows the person afterward, depends almost entirely on the age gap between the two people involved.

Who the Law Reaches

Pennsylvania’s age of consent is 16. The statutory sexual assault law criminalizes intercourse with a person under 16 only when the other party is at least four years older.¹ Once the younger person turns 16, an age-based statutory charge under § 3122.1 no longer fits, though other sex offenses involving force, incapacitation, or an authority relationship still can.

A separate and much harsher statute takes over when the child is under 13. That one, discussed below, does not care about the age gap at all.

Felony Grades by Age Gap

The statute splits statutory sexual assault into two felony grades tied to how much older the defendant is.

Second-Degree Felony

The charge is a second-degree felony when the minor is under 16 and the older person is at least four years older but fewer than eleven. The statute internally divides this into a four-to-eight-year gap and an eight-to-eleven-year gap. Both carry the same criminal penalty, but the split matters for sex offender registration later on.¹

First-Degree Felony

Once the age gap reaches eleven years or more, statutory sexual assault becomes a first-degree felony. That is the most serious grade of the § 3122.1 offense and it triggers lifetime registration.¹

When the Child Is Under 13: Rape of a Child

Cases involving a child under 13 are not charged as statutory sexual assault at all. Pennsylvania prosecutes them as rape of a child under 18 Pa.C.S. § 3121(c), a first-degree felony that applies regardless of how old the other person is or how close in age they are. The statute has no minimum age for the actor, so even a 14-year-old who has intercourse with a 12-year-old can technically be charged under it.²

If the child suffers serious bodily injury during the offense, § 3121(d) applies. It remains a first-degree felony but carries a much higher sentencing cap.²

Prison Time and Fines

Pennsylvania’s felony sentencing framework sets these maximums:

Statutory sexual assault, second-degree felony: up to 10 years in prison and a fine of up to $25,000.³
Statutory sexual assault, first-degree felony: up to 20 years in prison and a fine of up to $25,000.³
Rape of a child under 13: up to 40 years in prison. The statute overrides the normal 20-year cap for a first-degree felony.²
Rape of a child with serious bodily injury: up to life in prison.²

Judges sentence within these caps using state sentencing guidelines and the facts of the individual case.

The Close-in-Age Exception

Because § 3122.1 only applies when the older person is at least four years older, Pennsylvania has a built-in close-in-age carve-out, sometimes called a Romeo and Juliet provision. Two teenagers separated by less than four years fall outside the statute. A 17-year-old and a 14-year-old are three years apart, so their relationship is not statutory sexual assault.¹

That protection ends when the younger person is under 13. Rape of a child has no age-gap requirement, so a close-in-age situation involving a child that young can still produce a first-degree felony charge.²

Mistake of Age

Whether a defendant can argue they thought the minor was older depends on how young the minor actually was. If the charge requires the minor to be under 14, mistake of age is not a defense at all. What the minor said, what they looked like, whether an ID was checked, none of it matters.¹

When the charge turns on a threshold age above 14, such as the under-16 line, the defendant can raise a defense by proving, by a preponderance of the evidence, that they reasonably believed the minor was above that age. The defense exists in the statute but is narrow and hard to win.¹

Corruption of Minors

Prosecutors routinely add a corruption of minors count. Under 18 Pa.C.S. § 6301, any person 18 or older whose conduct violates Pennsylvania’s sexual offense laws with a minor under 18 commits a third-degree felony. Because this statute uses 18 as its cutoff rather than 16, it can reach a relationship that avoids statutory sexual assault entirely.⁴

An 18-year-old in a consensual relationship with a 16-year-old is past the age of consent for § 3122.1 but can still be charged with corruption of minors. The statute says explicitly that prosecution under it does not block prosecution under any other statute, so the counts can run in parallel.⁴

How Long Prosecutors Have to File

Prosecutors have 12 years from the date of the offense to bring charges for statutory sexual assault and other major sexual offenses.⁵ Because § 3122.1 victims are by definition under 16, that 12-year window often gives prosecutors well into the victim’s adult years to file.

Sex Offender Registration

A conviction triggers mandatory registration under Pennsylvania’s Megan’s Law. The tier, and how long registration lasts, depends on the specific subsection of the statute the person was convicted under, not just the felony grade.

Tier II, 25-year registration: a conviction under § 3122.1(a)(2), covering an eight-to-eleven-year age gap. Tier II registrants report in person twice a year.⁶
Tier III, lifetime registration: a conviction under § 3122.1(b), the first-degree felony for an eleven-year-or-greater gap. Tier III registrants report in person quarterly.⁶

On top of the periodic check-ins, registrants must appear within three business days of any change in home address, employer, school enrollment, phone number, email address, vehicle, or internet screen name, and at least 21 days before any international travel.⁶

Federal Passport Marking

The International Megan’s Law adds a consequence at the federal level. Under 22 U.S.C. § 212b, the State Department will not issue a passport to a covered sex offender unless it carries a unique identifier stating the person was convicted of a sex offense against a minor. Existing passports without the identifier can be revoked. International travel is not banned outright, but the marking stays on the passport for as long as registration is required, and leaving the country does not end that requirement.⁷
