Unlawful sexual conduct with a minor is one of the most heavily punished categories of crime in American law, with penalties that depend on the minor’s age, the age gap between the parties, and whether aggravating factors are present. Charges can run from a low-level felony or misdemeanor for an older teenager and a small age difference, up to a federal mandatory minimum of 30 years when the victim is under 12. On top of prison time, a conviction brings sex offender registration, residency and travel limits, and exposure to a civil lawsuit from the victim.
How Age of Consent Determines the Charge
Every state sets an age below which a person cannot legally consent to sexual activity. A majority of states set it at 16. Roughly a dozen set it at 18, and a handful place it at 17. Once someone older engages in sexual conduct with a person under the applicable age, the act is a crime whether the younger person seemed willing or not. Consent is not a defense when the other person is underage.
Two variables drive the severity of the charge. The first is the minor’s age. The second is the age gap between the two people. A 19-year-old with a 15-year-old sits in very different legal territory than a 35-year-old with a 12-year-old, and offense tiers reflect that. Younger victims and larger gaps produce the steeper charges.
A third factor can push the charge up another level: a position of trust. When the older person is a teacher, coach, counselor, clergy member, or family member, many states elevate the offense class even if the minor is close to the age of consent. The authority imbalance counts as an aggravator in its own right.
Close-in-Age Exemptions
About 45 states have some form of what is commonly called a Romeo and Juliet law. These provisions reduce or eliminate liability when two young people close in age engage in consensual activity and one or both are under the age of consent. The permitted gap is usually two to four years, with a few states allowing up to five. Some states additionally require the younger party to be at least 14 or 15.
The protection takes different forms depending on the state. It may reduce a felony to a misdemeanor, remove the registration requirement, or serve as a complete defense. The exemptions are narrow. One year outside the permitted gap means the full statutory rape law applies. A handful of states have no close-in-age exemption at all.
Federal Penalties
Federal law reaches these cases when the offense occurs on federal land, in federal prisons, across state lines, or in other areas of federal jurisdiction. The sentences are severe, and federal judges have far less discretion than state judges to go below the statutory floor.
Sexual abuse of a minor under federal law covers a victim between 12 and 15 when the offender is at least four years older. The maximum is 15 years in federal prison.1Office of the Law Revision Counsel. 18 USC 2243 – Sexual Abuse of a Minor For sexual contact short of a full sexual act, the maximum is two years for that same age group, doubling when the victim is under 12.2Office of the Law Revision Counsel. 18 USC 2244 – Abusive Sexual Contact
Aggravated sexual abuse applies when the victim is under 12, or when force or threats are used against any minor. The mandatory minimum is 30 years, and the maximum is life. A second federal conviction for the same offense produces a mandatory life sentence.3Office of the Law Revision Counsel. 18 USC 2241 – Aggravated Sexual Abuse A mandatory minimum means the judge cannot sentence below the floor regardless of mitigating circumstances.
State-Level Penalties
Most prosecutions happen under state law because most offenses occur entirely within one state’s borders. The numbers vary, but the structure is similar across states: graduated offense categories built around the type of contact, the victim’s age, and any aggravating factors.
At the lower end, sexual contact involving older teenagers and smaller age gaps may be charged as a misdemeanor or lower-level felony with a sentence of one to several years. At the upper end, penetration offenses against young children routinely draw 25 years to life, and many states attach mandatory minimums to those top-tier categories. Factors that push a sentence higher include:
- Use of force or threats, which elevates the charge and often triggers enhanced mandatory minimums.
- A position of trust, with teachers, coaches, foster parents, and similar authority figures facing higher felony classifications.
- A pattern of abuse across multiple incidents or multiple victims, which can produce consecutive sentences.
- Very young victims, with many states carving out separate categories for children under 12 or under 10.
Fines accompany prison sentences in most states and can reach into the hundreds of thousands of dollars for the highest felony classes. Courts frequently order restitution covering the victim’s counseling, medical expenses, and related costs. Those financial obligations survive the prison term.
Does Believing They Were Older Help
A common question is whether thinking the minor was old enough counts as a defense. In most situations the answer is no.
A majority of states treat these offenses as strict liability crimes. The prosecution does not need to prove the defendant knew the victim’s age. A fake ID, a lie about age, or a mature appearance does not matter. If the victim was underage, the crime is complete. That is a deliberate departure from the general rule that serious crimes require proof of a guilty mental state.
Federal law is slightly more forgiving in one narrow slice. For sexual abuse of a minor between 12 and 15, the defendant can raise the defense that they reasonably believed the other person was at least 16, but the defendant has to prove that belief by a preponderance of the evidence.1Office of the Law Revision Counsel. 18 USC 2243 – Sexual Abuse of a Minor “She told me she was 16” is not enough without corroborating circumstances. For offenses involving children under 12, no mistake-of-age defense exists at either the federal or state level.
Sex Offender Registration
The federal Sex Offender Registration and Notification Act sets a baseline every state must meet, and states can impose more. SORNA sorts offenders into three tiers based on the underlying offense:
- Tier I covers sex offenses that do not qualify for the higher tiers. Registration runs 15 years with annual in-person verification, and a clean 10-year record can shave five years off that period.4Office of the Law Revision Counsel. 34 USC 20915 – Duration of Registration Requirement
- Tier II covers offenses punishable by more than one year involving trafficking, enticement, abusive sexual contact against a minor, or production and distribution of child sexual abuse material. Registration runs 25 years with in-person verification every six months.5Office of the Law Revision Counsel. 34 USC 20911 – Relevant Definitions
- Tier III covers aggravated sexual abuse, sexual abuse, abusive sexual contact against a child under 13, and kidnapping of a minor. Registration is for life with in-person verification every three months.5Office of the Law Revision Counsel. 34 USC 20911 – Relevant Definitions
Registration means providing a current address, employment, and vehicle details to local law enforcement. Most states publish online registries with photographs and conviction details open to the public. Falling out of compliance by failing to register or failing to update after a move or job change is itself a federal crime carrying up to 10 years in prison.6Office of the Law Revision Counsel. 18 USC 2250 – Failure to Register If a violent crime is committed while unregistered, the penalty jumps to 5 to 30 years on top of the sentence for the new crime.
Life After a Conviction
The restrictions that follow a conviction often prove as disruptive as the sentence itself.
International Travel
Under International Megan’s Law, the State Department prints an identifier inside the passport of any covered sex offender stating that the bearer was convicted of a sex offense against a minor. Passport cards cannot be issued to covered offenders at all.7U.S. Department of State. Passports and International Megan’s Law Registered offenders must notify their local registry at least 21 days before any international travel, and the U.S. Marshals Service forwards that notice to the destination country.8U.S. Marshals Service. International Megan’s Law Complaint Form for Traveling Sex Offenders Failing to give notice or giving false information is punishable by up to 10 years in federal prison.6Office of the Law Revision Counsel. 18 USC 2250 – Failure to Register Even with proper notice, many countries refuse entry to registered sex offenders outright.
Where You Can Live and Work
Many states and cities bar registered offenders from living within a set distance of schools, parks, playgrounds, and childcare facilities. The buffer is typically 1,000 feet but ranges from 500 to 2,500 feet.9National Institute of Justice. Sex Offender Residency Restrictions: How Mapping Can Inform Policy In dense urban areas, these zones can wipe out most available housing.
Employment follows the same pattern. Registered offenders are generally barred from working in schools, childcare centers, and other settings serving children, and some jurisdictions extend bans to any job within a measured distance of such places. Professional licenses in education, healthcare, and social work are typically revoked or denied on conviction. The usable job market shrinks for the entire length of the registration period.
How Long Prosecutors Have to Charge
The window for bringing charges has expanded sharply. At the federal level, there is no statute of limitations for any felony sexual offense covered by the relevant chapters of Title 18, including sexual abuse of a minor and aggravated sexual abuse.10Office of the Law Revision Counsel. 18 USC 3299 – Child Abduction and Sex Offenses Federal prosecutors can bring charges decades after the fact.
States have moved in the same direction. As of late 2025, 44 states had eliminated the criminal statute of limitations for child sexual abuse. The remaining states generally allow prosecution for at least 10 years after the offense or after the victim reaches adulthood. Many states have also extended or eliminated civil deadlines, and roughly 30 have opened revival windows that let victims file civil claims after old deadlines had already run.
Civil Lawsuits on Top of Criminal Charges
A criminal prosecution is not the only legal exposure. Victims can file a separate civil lawsuit seeking money damages, and the civil case runs independently from any criminal case. A defendant acquitted at trial can still lose the civil case because the burden of proof is lower: preponderance of the evidence, meaning more likely than not, rather than beyond a reasonable doubt.
Civil damages typically cover therapy and medical costs, lost future earnings, and emotional suffering, and courts can add punitive damages in egregious cases. Unlike criminal fines, civil judgments go directly to the victim, and they can reach substantial amounts.
