A Top Secret clearance lasts five years before it must be reinvestigated, and a Secret clearance lasts ten. That five-year clock starts the day your background investigation closes, not the day you first walk into a vault or start a new job. Two things complicate the simple answer: the government is replacing the fixed five-year cycle with continuous vetting, and your clearance can end early either through revocation or by sitting unused for too long after you leave a cleared position.1U.S. Department of State. Continuous Evaluation (CE) Program
The Five-Year Reinvestigation Cycle
Under the traditional model, Top Secret eligibility is reinvestigated every five years. The same five-year timeline applies if your clearance includes Sensitive Compartmented Information access. Secret-level clearances run on a ten-year cycle by comparison.1U.S. Department of State. Continuous Evaluation (CE) Program
The investigation that supports a Top Secret clearance is called a Tier 5 (formerly the Single Scope Background Investigation). It covers years of personal history and pulls in employment records, financial data, criminal records, interviews with references and neighbors, and foreign travel and contacts. You feed most of that information into Standard Form 86, the questionnaire for national security positions.2U.S. Office of Personnel Management. Standard Form 86 – Questionnaire for National Security Positions Because the process takes months, plan on the reinvestigation being initiated well before the five years are up rather than exactly at the deadline.
Continuous Vetting Is Changing the Timeline
The fixed five-year cycle is being phased out. Under a government-wide initiative called Trusted Workforce 2.0, periodic reinvestigation is giving way to continuous vetting, an automated system that monitors cleared personnel on an ongoing basis rather than waiting for a scheduled review every few years.3Defense Counterintelligence and Security Agency. Continuous Vetting
Continuous vetting draws from criminal, terrorism, and financial databases along with public records at any point during your period of eligibility. If something concerning shows up, such as a new arrest, a financial judgment, or a foreign contact, it gets flagged for review in near real time instead of sitting undiscovered until the next scheduled reinvestigation.3Defense Counterintelligence and Security Agency. Continuous Vetting The earlier Continuous Evaluation program ran automated checks between reinvestigation cycles; continuous vetting goes further by aiming to eliminate the fixed cycle entirely.4Office of the Director of National Intelligence. Continuous Evaluation Overview
Rollout has been phased across the federal workforce, so many clearance holders are currently subject to both the legacy periodic reinvestigation and continuous vetting. Whether you are fully under the new system depends on your agency and when your population was onboarded. For planning purposes, treat the five-year cycle as still operative until your security office tells you otherwise.
What Keeps Your Clearance Alive Between Reviews
Between reinvestigations, your clearance is not on autopilot. Security Executive Agent Directive 3 requires you to self-report certain events as they happen. Failing to report can itself become a security concern, sometimes a worse one than whatever you failed to report.
- Contact with a known or suspected foreign national that touches classified or sensitive information, could create a conflict of interest, or could be used as leverage.5Office of the Director of National Intelligence. Security Executive Agent Directive 3 – Reporting Requirements
- Planned unofficial foreign travel, per your agency’s procedures.5Office of the Director of National Intelligence. Security Executive Agent Directive 3 – Reporting Requirements
- Significant financial trouble such as bankruptcy or wage garnishment.5Office of the Director of National Intelligence. Security Executive Agent Directive 3 – Reporting Requirements

How a Clearance Can End Early
A Top Secret clearance can be suspended or revoked at any point during its validity period. The adjudicative guidelines list thirteen categories of concern, and four drive most losses.
Financial irresponsibility is the single most common reason clearances are denied or revoked, on the theory that someone buried in debt is more vulnerable to bribery or coercion. The guidelines flag inability to satisfy debts, a pattern of missed obligations, and deceptive practices like tax evasion or check fraud.7Office of the Director of National Intelligence. SEAD 4 – National Security Adjudicative Guidelines There is no bright-line debt-to-income ratio, but recent bankruptcy, multiple collections, or debts rising while income stays flat all draw scrutiny. Financial concerns are also among the most mitigatable if you can show a repayment plan and changed behavior.
Criminal conduct raises doubts about judgment and applies whether or not you were formally charged. Drug and alcohol issues have separate guidelines; illegal drug use after being granted a clearance is extremely hard to mitigate. Foreign influence covers close ties to foreign nationals or governments that could create divided loyalties or coercion risk.7Office of the Director of National Intelligence. SEAD 4 – National Security Adjudicative Guidelines
If a revocation is proposed, Executive Order 12968 gives you written reasons, access to the documents behind the decision, the right to respond in writing, the right to appear in person, and the right to appeal to a panel of at least three members with two from outside the security field. Response deadlines are short, typically 20 days from a Statement of Reasons, so time matters.8GovInfo. Executive Order 12968 – Access to Classified Information
The 24-Month Rule After You Leave a Cleared Job
Your clearance does not vanish the day you leave a cleared position, but it does go inactive. Under Department of Defense policy, eligibility can be reinstated without a new investigation if three conditions are met: your last investigation closed within the previous five years, you have been separated from government service for no more than 24 months, and there is no indication you no longer meet eligibility standards.9Department of Defense. DoD Manual 5200.02 – Procedures for the DoD Personnel Security Program You will also certify in writing on an SF-86C that nothing has changed, and an appropriate records check must come back clean.
Past 24 months without a sponsoring employer, reinstatement generally requires a new Tier 5 investigation from scratch, with the same timeline and cost as the original. If you are leaving cleared work and think you might return, line up the next position inside that window. It is a hard cutoff.
Interim Top Secret Clearances
Because a full Tier 5 investigation takes months, agencies can grant an interim Top Secret clearance based on the minimum investigative checks while the full investigation runs. That lets you start work before the final determination.
An interim Top Secret gives access to most Top Secret information but restricts COMSEC, NATO, and Restricted Data to the Secret and Confidential levels. It does not include SCI access, which requires a completed investigation and often a polygraph. Roughly 20 to 30 percent of interim clearances are denied, but that is not a prediction of the final outcome; the final denial rate for completed investigations sits near one percent. An interim denial usually means the quick screening surfaced something that needs the full investigation to resolve.
