Felony Sex Crimes: Federal Tiers, Registration, and Restrictions

Federal felony sex crimes are classified by letter grade rather than by degree, and every conviction for a qualifying offense triggers mandatory sex offender registration under the Sex Offender Registration and Notification Act (SORNA). Federal law sorts all felonies into Classes A through E based on the maximum prison term the statute authorizes, with Class A carrying life or death and Class E carrying more than one year but less than five.¹ SORNA then places the person into one of three tiers that dictate how often they must report in person and for how many years — 15, 25, or life.

Federal Classification Uses Letters, Not Degrees

First-, second-, and third-degree labels come from state criminal codes. Federal law has no degree system. A federal sex offense is a Class A, B, C, D, or E felony depending on the maximum authorized sentence, and that grade drives collateral consequences like supervised release terms and statute of limitations rules.¹

Federal jurisdiction over sex offenses is also narrower than many people assume. The core sexual abuse statutes reach conduct within the special maritime and territorial jurisdiction of the United States — federal land, military installations, national parks, Indian country — and inside federal prisons.² Offenses involving children under twelve and the production of child sexual abuse material reach further because they include interstate elements. Most sex crime prosecutions happen in state court under state statutes. SORNA registration, however, applies nationwide regardless of whether the underlying conviction is federal, state, military, or tribal.

The Main Federal Sex Offenses and Their Penalties

Aggravated Sexual Abuse

This is the most severely punished federal sex offense. It covers a sexual act committed by force, by threats of death or serious injury, or by drugging or rendering someone unconscious. The authorized sentence is any term of years up to life. When the victim is under twelve, the mandatory minimum is 30 years, and a second conviction in this category carries mandatory life.²

Sexual Abuse

One step down, this statute covers sexual acts against a person who cannot understand what is happening or is physically unable to resist or communicate unwillingness. The ceiling is any term of years up to life, though guidelines and judicial discretion often produce shorter sentences where no weapon or extreme violence is involved.³

Sexual Abuse of a Minor or Ward

This offense applies when someone commits a sexual act with a person who is at least twelve but under sixteen, and at least four years younger than the offender. It also covers sexual acts with someone in the custody or supervision of the offender in a federal institution. Maximum sentence: 15 years.⁴

Abusive Sexual Contact

This statute reaches sexual touching rather than a full sexual act. The maximum depends on which more serious statute the contact would have violated had it been a sexual act: 10 years if it corresponds to aggravated sexual abuse, 3 years if it corresponds to sexual abuse, and 2 years for the minor or ward variant or for other nonconsensual contact. When the victim is under twelve, each of those maximums doubles.⁵

Sexual Exploitation of Children

Producing child sexual abuse material carries a first-offense range of 15 to 30 years. A second conviction raises the floor to 25 years and the ceiling to 50. A third or subsequent conviction carries 35 years to life. If the offense results in a death, the sentence is either death or 30 years to life.⁶ Because this statute reaches anyone who uses interstate commerce or the mail system, it has nationwide applicability.

Who Must Register and When

A person convicted of a qualifying sex offense in any state, D.C., a U.S. territory, a federally recognized tribe, the federal system, or the military must register under SORNA. Every jurisdiction has to maintain a registry meeting SORNA’s minimum standards.⁷

Registration is due before release from prison. If there is no prison sentence, it is due within three business days of sentencing. The person must register in every jurisdiction where they live, work, or attend school.⁷

Registrants must provide their full name and any aliases, Social Security number, every residence, every employer’s name and address, any school attended, license plate and description of every vehicle they own or drive, and detailed plans for any international travel including dates, destinations, carrier and flight numbers, and purpose.⁸ Any change to name, address, employer, or school enrollment must be reported in person within three business days.⁷

The Three Registration Tiers

SORNA sorts every registrant into one of three tiers based on the offense. The tier controls two things: how often the person must appear in person to verify their information, and how long the registration obligation lasts.

Tier I: 15 Years, Yearly Check-Ins

Tier I is the residual category. It captures any qualifying sex offense that does not meet the definition of Tier II or Tier III.⁹ Verification is annual, and the obligation runs 15 years.¹⁰ A Tier I registrant who maintains a clean record for 10 years, completes supervised release, and completes an approved treatment program can shorten that period by five years, ending it at 10.¹¹ “Clean” for this purpose means no new conviction carrying more than a year of imprisonment and no new sex offense conviction.

Tier II: 25 Years, Semiannual Check-Ins

Tier II covers offenses punishable by more than one year of imprisonment that involve minors, including sex trafficking of children, enticement of a minor, using a minor in a sexual performance, and producing or distributing child sexual abuse material. Abusive sexual contact with a minor also falls here, as does any sex offense committed by someone who is already a Tier I offender.⁹ Verification is every six months for 25 years.¹⁰ Federal law does not offer Tier II registrants a clean-record reduction.

Tier III: Lifetime, Quarterly Check-Ins

Tier III is reserved for the most serious offenses: aggravated sexual abuse, sexual abuse as defined in the federal statutes, abusive sexual contact against a child under thirteen, kidnapping of a minor by anyone other than a parent, and any sex offense committed by someone already registered as a Tier II offender.⁹ Verification is every three months, and the obligation lasts for life.¹⁰ Federal law provides no petition process to remove a Tier III adult offender from the registry. The single narrow exception applies to a person whose Tier III status comes from a juvenile delinquency adjudication, who can earn a reduction after 25 clean years.¹¹

Time in custody or civil commitment does not count toward any of these periods.¹¹ The clock starts on release, not on the date of conviction.

Missing a Registration Deadline Is a Separate Federal Crime

Failing to register or update registration information carries up to 10 years in federal prison on its own. If the person commits a violent crime while unregistered, the penalty jumps to a mandatory minimum of five years and a maximum of 30, served consecutively to the sentence for the violent crime.¹² Each state must also criminalize failure to register with a maximum term greater than one year, so a missed deadline can be prosecuted at both levels.⁷

Restrictions That Come With Registration

Where You Can Live

Many jurisdictions impose buffer zones prohibiting registrants from living near schools, playgrounds, day care centers, and parks. Typical distances range from 500 to 2,500 feet, and they vary by jurisdiction and offense type. Violating a buffer can trigger arrest and revocation of parole or probation, and the compliant portions of many urban areas are small enough that finding housing is one of the biggest post-release challenges registrants face.

Where You Can Work

Most jurisdictions bar registrants from jobs involving contact with children — teaching, coaching, child care — and often extend the bar to healthcare and transportation involving vulnerable populations. Professional licenses in fields like law, medicine, and nursing are frequently revoked or denied automatically on a felony sex crime conviction.

International Travel and Your Passport

SORNA requires registrants to notify their registry officials of planned international travel at least 21 days before departure, with destination country, flight details, dates, and purpose.¹³ Skipping that notice is grounds for federal prosecution.

The International Megan’s Law also requires the State Department to print a unique identifier inside the passport of any covered sex offender whose registration obligation is still active.¹⁴ The identifier reads: “The bearer was convicted of a sex offense against a minor, and is a covered sex offender pursuant to 22 USC 212b(c)(1).”¹⁵ Passport cards are not issued to covered sex offenders at all, and moving abroad does not remove the identifier — it stays as long as registration is required.

Social Media and Online Identifiers

The Supreme Court struck down a blanket state ban on registered sex offenders using social media in Packingham v. North Carolina, holding that such a prohibition violates the First Amendment.¹⁶ Narrower laws — for instance, prohibiting a registrant from using a platform to contact minors — remain permissible. Regardless of what a platform allows, registrants must still disclose all email addresses, usernames, and other online identifiers to law enforcement under SORNA; that information is used for monitoring and is not published on public registry websites.

Civil Commitment Can Extend Custody Past the Sentence

Prison time is not always the outer boundary of federal custody. Under 18 USC 4248, the Attorney General can certify a person in federal custody who is nearing release as sexually dangerous, which freezes the release date pending a hearing.¹⁷ If a court finds by clear and convincing evidence that the person meets the standard, it commits the person to the custody of the Attorney General. The government must first try to transfer the person to the state where they live or were convicted; if no state accepts, the person stays in a federal facility. Commitment has no fixed end date. It continues until a court finds by a preponderance of the evidence that the person no longer poses a danger, either outright or under supervised treatment. Civil commitment is rare, but it can extend confinement by decades beyond the original prison sentence.
