How Often Do Sex Offenders Have to Register Under SORNA?

Under the federal Sex Offender Registration and Notification Act (SORNA), how often sex offenders have to register depends on the tier assigned to their offense: Tier I registrants appear in person once a year, Tier II every six months, and Tier III every three months.¹ States can and do impose stricter or differently structured rules, so the schedule that actually governs any individual registrant is the one set by the state where they live, work, or attend school.

Which Tier Sets Your Schedule

SORNA sorts offenses into three tiers by severity, and the tier decides both check-in frequency and how many years the obligation lasts.²

Tier I is the catch-all category for any sex offense that doesn’t meet the Tier II or Tier III definition. Verification is annual, and the registration period runs 15 years.

Tier II covers offenses punishable by more than a year in prison that involve conduct such as sex trafficking of a minor, enticement of a minor, using a minor in a sexual performance, or distributing child sexual abuse material. It also captures any Tier I registrant who commits a new qualifying offense. Check-ins are every six months for 25 years.

Tier III is reserved for the most serious offenses punishable by more than a year, including aggravated sexual abuse, sexual abuse, sexual contact with a child under 13, and kidnapping of a minor by a non-parent. Anyone who reoffends after reaching Tier II also lands here. Verification is quarterly, and the obligation is for life.

A number of states don’t use SORNA’s offense-based tiers at all. Some classify registrants by individualized risk assessment instead, which can raise or lower both the frequency and the duration set by federal law. Check the registry rules in your state, not just the federal categories, to know what schedule applies to you.

What Happens at Each Check-In

The scheduled visit has to be in person, at a designated law enforcement office. SORNA requires each appearance to include a new photograph and a review of the physical description and other identifying information on file.¹ In practice, an officer walks through the details on record: home address, employer, any school enrollment, vehicles. Anything that has changed gets updated on the spot.

These visits can’t be skipped or postponed indefinitely. A missed appearance is treated the same as any other registration violation.

Updates That Can’t Wait for the Next Visit

The tier schedule is a floor, not the whole picture. Separate from the annual, semiannual, or quarterly appearance, a registrant has to report certain changes as they happen. SORNA requires that registration be kept current in every jurisdiction where the person lives, works, or goes to school.³

The changes that most often trigger a reporting duty are moving to a new address, starting or leaving a job, enrolling in or dropping out of school, and acquiring or changing a vehicle. Most states give registrants a narrow window, commonly three to ten business days, to report the change in person. Waiting until the deadline is risky; reporting as soon as the change happens is the safer approach.

An interstate move creates a double duty: notify the current jurisdiction before leaving, then register in person in the new state after arriving. Because the new state may classify offenses differently, the check-in frequency and remaining duration can shift once you cross the line. Contact the new state’s registry right away to confirm what the schedule looks like going forward.

International travel has its own advance-notice rule. Registrants must notify registry officials of any planned trip abroad at least 21 days before departure, and the registry forwards the information to the U.S. Marshals Service’s National Sex Offender Targeting Center.⁴ Traveling internationally without providing that notice is a separate federal crime.

How Long the Obligation Lasts, and Whether It Can Be Shortened

The registration periods track the tiers: 15 years for Tier I, 25 years for Tier II, and life for Tier III.

Tier I registrants have a statutory path to a shorter period. Ten consecutive years with a clean record cuts five years off the total, ending the obligation after a decade. A clean record under SORNA means no felony or sex offense convictions, successful completion of any supervised release, and completion of an approved sex offender treatment program.

Adult Tier II and Tier III registrants have no equivalent federal reduction. The 25-year or lifetime clock runs its full length unless the state provides its own mechanism to petition for removal, and those procedures vary widely from state to state.

Juvenile Tier III registrants have a separate path: 25 years with a clean record can end the obligation, using the same clean-record standard.⁵

Penalties for Missing a Check-In

Failing to register, or failing to keep the registration current, is a stand-alone crime separate from the underlying conviction. Under 18 U.S.C. § 2250, knowingly failing to register or update as SORNA requires carries up to 10 years in federal prison, a fine, or both.⁶

Federal charges typically come into play when the original conviction was federal or when the registrant has crossed state lines or entered Indian country. States prosecute their own failure-to-register cases too, often at the felony level.

Penalties climb sharply if a registrant commits a violent crime while out of compliance. In that situation, the federal statute imposes a mandatory minimum of 5 years and a maximum of 30 years, served consecutively on top of the sentence for the violent crime and any sentence for the registration violation itself.⁶

There is one narrow defense in the statute. A registrant can try to show that uncontrollable circumstances prevented compliance, that they did not recklessly contribute to those circumstances, and that they complied as soon as the obstacle was removed. All three elements have to be established, and courts read the defense strictly.⁶
