SORNA Registration Tiers After a Federal Conviction.

Last Updated on: 4th August 2026, 01:33 am

Unlike the state-level SORNA registration tiers, the federal SORNA registration tiers are offense-based. In other words, the federal registration tiers are based on the specific offense(s) for which an individual has been convicted, rather than an individualized risk score.

A federal registration tier determines:

• The length of the registration period
• How frequently an individual must verify their information

There are three registration tiers under SORNA. Tier I offenses require registration for a minimum of 15 years, with verification of registration information every year; Tier II offenses require registration for a minimum of 25 years, with verification of registration information every six months; and Tier III offenses require registration for the lifetime of the individual, with verification of registration information every three months.

Federal registration requirements and state registration requirements may both apply after a conviction. The SORNA registration period begins upon release from custody for an individual sentenced to imprisonment, and at sentencing for an individual who is not sentenced to imprisonment.

The federal and state registration periods run concurrently, and the state registration periods can exceed the federal registration period. Registration is required in each jurisdiction where the individual resides, works, or attends school, and initially in the jurisdiction of conviction if it differs from the jurisdiction of residence.

Many states also have registration and verification requirements beyond what is required under SORNA, and compliance with both state and federal law is required. For more information, we recommend contacting one of our attorneys.

Registration triggers may include:

• Federal conviction for a registered sexual offense
• State conviction for a registered sexual offense (sentencing for state offenses is governed by state law and procedure)
• Federal or state sentencing after a guilty plea or no-contest plea
• Other circumstances determined to be grounds for registration under federal or state law

For information on what to do if you are facing registration under SORNA, we recommend speaking with a lawyer who has experience with these issues.

How Long Does a Federal SORNA Tier Last?

A Tier I offense requires registration for a minimum of 15 years under 34 U.S.C. § 20915. Tier I registrants must also verify their registration information in person once each year.

A Tier II offense requires registration for a minimum of 25 years under 34 U.S.C. § 20915. Tier II registrants must also verify their registration information in person every six months.

A Tier III offense requires registration for the individual’s lifetime under 34 U.S.C. § 20915. Tier III registrants must also verify their registration information in person every three months.

The registration period begins at the time of sentencing if no imprisonment is imposed. If imprisonment is imposed, the registration period begins at the time of the individual’s release from prison.

In order to remain compliant with SORNA, the individual must also abide by state registration laws. As noted, the registration period under federal and state law will run concurrently, and states are allowed to impose longer registration periods than are mandated under federal law. States can also impose different verification requirements.

The registration period will begin to run at the time of sentencing in the case of a federal conviction only where no term of imprisonment is imposed; if the individual is sentenced to imprisonment, registration must be completed before the individual finishes serving that sentence. If the state of the individual is requiring registration under a separate state law, that registration period will run from the date of sentencing.

Any state or states in which the individual resides, has previously resided, or is employed are states that require registration in each case. Again, it is possible for federal and state registration requirements to both be applicable.

If you have been sentenced to a Tier I, Tier II, or Tier III offense, and are wondering whether you have registration requirements under federal law, state law, or both, or what the requirements are, we recommend speaking with an attorney who can assess your situation in more detail.

How do common federal convictions map to federal SORNA tiers?

The federal SORNA tiers are described in a large list under 34 U.S.C. § 20911. This list includes a broad range of offenses and their corresponding tiers. Some of the key provisions of § 20911 include:

• Federal Child Pornography Possession Convictions. Whether federal child pornography possession convictions trigger registration under SORNA depends on whether the offense qualifies as a “sex offense” under 34 U.S.C. § 20911. The statute of 34 U.S.C. § 20915 also contains language that requires registration in any case where a person is convicted of a sexual offense, regardless of whether it is listed. The statute lists 18 U.S.C. § 2422(b) (sexual enticement of a minor), 18 U.S.C. § 2423 (interstate travel in aid of sexual exploitation), and 18 U.S.C. § 2251 (production of child pornography) as example sexual offenses that require registration. Thus, under federal law, it appears that federal child pornography possession convictions trigger registration.
• The Residual Tier. 34 U.S.C. § 20911(2) says that Tier I is the residual tier. In other words, any sex offense conviction that does not meet the definition of a Tier II or Tier III offense is a Tier I offense.
• Tier II Offenses. 34 U.S.C. § 20911(3) lists various offenses that qualify as Tier II offenses. These include:
• U.S.C. § 2422(b) (enticement of a minor)
• 18 U.S.C. § 2423(a) (transportation with intent to engage in criminal sexual activity)
• Production or distribution of child pornography under 34 U.S.C. § 20911(3)(B)(iii).
• Note that child pornography possession is not among the list of child pornography offenses listed in § 20911(3)(B). For example, possession of child pornography under 18 U.S.C. § 2252A(a)(5)(B) or 18 U.S.C. § 2252A(a)(6)(B) is not included. However, these offenses can still require registration as tier I offenses, because they fall within the definition of a “sex offense” in 34 U.S.C. § 20911(5).
• Tier III Offenses. 34 U.S.C. § 20911(4) lists various offenses that qualify as Tier III offenses. The scope of Tier III registration obligations under federal law is similar to the scope of registration requirements under the state sex offender registration laws in the federal government’s “ model” SORNA statute. These include offenses comparable to 18 U.S.C. § 2241 or 18 U.S.C. § 2242 (sexual assault) and abusive sexual contact where the victim was under the age of thirteen. Again, these are just a sampling of the offenses that can require registration.
• In the case of federal charges, prosecutors must meet the requirements of the Federal Rules of Criminal Procedure. These rules establish the rules of criminal trials in the federal district courts. In addition, prosecutors must meet the requirements of the applicable state rules of criminal procedure. These state rules apply if the prosecution is taking place in state court.

Can An Attempt Count or A Prior Offense Change a Federal SORNA Tier?

Depending on the offense in question, it is possible that an attempt count or a prior offense will change the federal SORNA registration tier.

• Attempt or Conspiracy Counts. An attempt or conspiracy to commit an offense listed in 34 U.S.C. § 20911(3)(A) is itself a Tier II offense. Similarly, an attempt or conspiracy to commit an offense listed in § 20911(4)(A) is itself a Tier III offense.
• Aiding and Abetting. In cases involving aiding and abetting, the individual is deemed a principal under 18 U.S.C. § 2. This is true regardless of whether the individual is a Tier I, Tier II, or Tier III sex offender under the statute.
• Recidivism. A repeat offender can have a higher federal SORNA registration tier than a first-time offender when the later offense is punishable by imprisonment for more than one year and occurs after the offender became a Tier I offender. For example, a later qualifying offense may place a Tier I offender in Tier II. Similarly, an individual in a Tier II position may have their classification elevated to Tier III if they commit another sex offense.
• Multiple Victims. While the federal SORNA registration tiers can be elevated due to recidivism, no such provision exists for multiple victims. The definition of the individual tiers in 34 U.S.C. § 20911 do not account for multiple victims.
• Victim Age. The victim’s age can affect whether a federal offense is a Tier I, Tier II, or Tier III offense. Child sex offenses can trigger registration under 34 U.S.C. § 20911 and the registration requirements in 34 U.S.C. § 20913. The age of the victim in an abusive sexual contact offense also matters, since that offense can be a Tier II offense or a Tier III offense depending on whether the victim was under the age of thirteen.

Who Determines the SORNA Tier Following a Federal Sentencing?

SORNA defines a “jurisdiction” as a State, the District of Columbia, the Commonwealth of Puerto Rico, Guam, American Samoa, the Northern Mariana Islands, the United States Virgin Islands, and, to the extent provided and subject to the requirements of section 20929 of this title, a federally recognized Indian tribe.

SORNA does not identify a federal registry office that is comparable to local offices in various states. Instead, it imposes registration obligations that fall under the authority of “the appropriate registration jurisdiction.”

In the case of a federal conviction, the federal district court’s judgment may state that registration is required as a condition of supervised release. Again, the registration obligation is placed within a “registration jurisdiction.” However, the judgment will not typically designate a particular SORNA tier.

Ultimately, individuals will likely be classified as a registered sex offender according to the policies and procedures of the relevant registration jurisdiction. Often, federal law requires registration when state registries have their own procedures for classifying federal convictions. Again, while these classifications are similar, they do not necessarily result in the same registration requirements.

Even if a state classifies a federal conviction under a state registration statute and applies the relevant state registration obligations, federal law may still mandate registration. Some states have specific provisions in their registration statutes which explicitly acknowledge the application of registration under federal law, and which expressly defer to federal registration tiers and periods in the event of a conflict.

But, the converse is also true. Even if a federal registration period has expired, the individual may still be required to register under state law.

While a reduction of the federal registration period is not uncommon under 18 U.S.C. § 3583(e), such reductions do not inherently terminate registration under state law.

In the case of a reduction based on federal law, whether registration can also be removed under state law, and what procedure can lead to such a removal, depends on the relevant state statute. Again, the federal court’s registration-removal authority depends on the underlying statute that imposed registration and the procedural vehicle brought to the court.

As a result, when it comes to matters of registration removal, it is vital to understand which laws apply. If you have questions about your registration obligations or are looking to determine if registration removal is a possibility, our attorneys can provide more information.

Can a Federal SORNA Registration Period Be Shortened?

Under federal law, there are certain provisions that allow individuals to seek a reduction of their registration obligations. While those provisions are contained in the federal statute 34 U.S.C. § 20915, they are written as permission provisions. This means that, subject to a judicial determination, the court has the authority to grant a reduction, but there is no constitutional right to one.

Specifically, the federal SORNA statute provides for a clean-record reduction in the following cases:

• Tier I Registration Period. Individuals who are Tier I registrants may seek to reduce their federal registration period from 15 years down to 10 years.
• No Tier II or Tier III Reduction for Adult Offenders. Under the current federal SORNA registration statutes, there is no clean-record reduction available for Tier II adult offenders, and there is no clean-record reduction available for Tier III adult offenders.

In order to qualify for a Tier I registration period reduction, an individual must be able to demonstrate a clean record. SORNA defines a “clean record” as one in which the individual has (i) no felony convictions during the registration period; (ii) no convictions for sex offenses during the registration period; (iii) has successfully completed any terms of supervised release, probation, or parole that were imposed during federal sentencing; and (iv) has successfully completed an appropriate sex-offender treatment program certified by a jurisdiction or by the Attorney General.

While the federal SORNA statute only provides for a Tier I clean-record reduction, many state registration statutes provide for reductions of individuals’ registration periods as well. However, as we have discussed throughout this article, the federal registration period runs concurrently with the state registration period. As a result, even if an individual obtains a reduction of their state registration period, a federal registration period will still apply for the minimum number of years mandated under federal law.

Again, while SORNA allows for a reduction of the Tier I registration period, it does not grant the individual a right to one. Instead, it allows the court to grant the request as it deems appropriate. It is therefore possible to seek the reduction, but it will be up to the federal judge’s determination as to whether the request should be granted.

We recommend speaking with a lawyer in order to fully understand your registration obligations. Additionally, if you are seeking to seek a reduction of your registration period, we recommend speaking with a lawyer who can advise you based on the federal and state registration statutes and your specific circumstances.

Can Missed Registration Become a Separate Federal Case?

Yes. Failure to register can lead to a separate federal case under 18 U.S.C. § 2250. Under § 2250, if a registered sex offender either fails to register or fails to renew their registration and “knowingly” does so, they face criminal penalties. Under 18 U.S.C. § 2250, this can include a maximum prison term of ten years, along with supervision and fines.

Importantly, since violation of registration requirements under SORNA constitutes a separate federal offense, it can be charged even if the offender’s original sex offense was not a federal offense. This means that a registration violation under SORNA can lead to a separate federal case regardless of whether the original offense was federal, state, tribal, territorial, or occurred in foreign jurisdictions.

• Registration Violation as a Revocation Trigger for Supervised Release. In the case of a federal conviction and federal sentencing, a registration violation can also trigger revocation of the individual’s federal supervised release. In this scenario, the offense of failure to register may become a matter for enforcement under the terms of supervised release.

The scope of 18 U.S.C. § 2250 includes criminal offenses prosecuted under:

• Federal Law
• Military Law
• D.C. Law
• Tribal Law
• Territorial Law

State law registered sex offenders may also qualify to be prosecuted under 18 U.S.C. § 2250. However, state offenders must generally demonstrate that they are in federal jurisdiction, because they were convicted under state law. In order to establish federal jurisdiction in state cases, a prosecution under § 2250 must generally demonstrate that the individual qualifies under § 2250(a)(2)(B).

Pursuant to 18 U.S.C. § 2250(a)(2)(B), a state offender is in federal jurisdiction if they:

• In the course of a travel that has been commenced and continued within the United States or between the United States and a foreign country, move from one state or territory to another state or territory
• Are a member of an Indian tribe or are affiliated with an Indian tribe, and commit a sex offense on Indian lands
• Travel in or from the United States with the intent to commit a sex offense in a foreign country

Conversely, in the case of a federal sex offense conviction, the individual is already in federal jurisdiction. This means that any prosecution for failure to register under 18 U.S.C. § 2250(a)(2)(A) does not need to meet the criteria of travel under § 2250(a)(2)(B).
