Across the federal government, roughly 2% of final security clearance applications are denied each year. That number understates the real attrition, though: it excludes applicants who withdraw or are dropped before a formal decision, intelligence community agencies deny at rates several times higher than the Department of Defense, and interim clearances — the temporary access granted while your investigation is still running — are declined 20% to 30% of the time. So the honest answer to how often security clearances are denied depends heavily on which agency, which clearance level, and which stage of the process you’re asking about.
Final Denial Rates by Agency and Level
The Office of the Director of National Intelligence publishes annual reports on clearance determinations, but no single government-wide denial rate exists that covers every agency and level. The public data that does exist tells a consistent story. Final denial rates at most agencies sit in the low single digits. Intelligence community agencies run noticeably higher.
The Department of Defense handles the vast majority of clearance adjudications, and its final denial rate has historically been well under 5%. The National Security Agency has historically led federal agencies in combined denial and revocation rates, with the Central Intelligence Agency close behind. Exact percentages shift year to year, and by the time breakdowns become public they are often several years old.
Clearance level matters too. Top Secret investigations are more thorough than Secret ones, and denial rates rise with them. The logic is straightforward: the deeper investigators dig, the more potentially disqualifying information turns up. At agencies that require a polygraph for Top Secret or TS/SCI access, the added exposure pushes denial rates higher still.
One caveat rides on top of all these numbers. The 2% figure counts formal denials, not everyone who fails to end up with a clearance. Applicants with serious issues frequently withdraw, get dropped by their sponsoring agency, or never finish the paperwork. The share of people who start the process and don’t come out the other end with access is meaningfully higher than 2%.
Why Interim Clearances Are Declined So Much More Often
An interim clearance lets you start working with classified material while the full background investigation continues. The declination rate for interims runs 20% to 30%, an order of magnitude above the roughly 2% for final decisions. That gap surprises a lot of applicants.
The reason is procedural. Interim decisions are made quickly, off a single review of your SF-86 and an initial records check. There’s no full investigation behind them and no layered adjudicative review. Anything on your form that raises a concern — even something you could easily mitigate with context — can trigger a decline. Final decisions, by contrast, run through multiple levels of adjudicative review that weigh favorable and unfavorable information together.
An interim decline is not a final denial. You cannot appeal it, and the agency isn’t required to explain it. You wait for the investigation to finish and for a final adjudicator to look at the complete picture. Plenty of applicants who lose an interim end up with a favorable final determination.
Why Clearances Get Denied
Adjudicators work from 13 guidelines laid out in Security Executive Agent Directive 4, covering allegiance to the United States, foreign influence, foreign preference, sexual behavior, personal conduct, financial considerations, alcohol consumption, drug involvement and substance misuse, psychological conditions, criminal conduct, handling protected information, outside activities, and use of information technology systems.1Office of the Director of National Intelligence. SEAD 4 – National Security Adjudicative Guidelines No single factor decides the outcome. Adjudicators apply a “whole person” analysis, weighing everything available, good and bad, to judge whether granting access would create unacceptable risk.
Financial Problems
Financial issues are the single most common reason clearances are denied. The concern isn’t the debt itself but what it signals about judgment and vulnerability. Someone financially overextended is considered at greater risk of taking illegal steps to get money, including espionage.1Office of the Director of National Intelligence. SEAD 4 – National Security Adjudicative Guidelines There’s no dollar threshold that automatically disqualifies. Someone owing $5,000 can be denied; someone owing $150,000 can be approved. The pattern matters more than the total: an inability to satisfy debts, a history of missed obligations, and unfiled or unpaid federal and state taxes.
Tax problems draw especially sharp scrutiny. DOHA cases regularly show applicants who ignored filings for multiple years fighting uphill even after catching up. A structured repayment plan, financial counseling, or evidence that the debt came from circumstances beyond your control — job loss, medical emergency, divorce — can mitigate the concern.
Drug Involvement
Any illegal drug use raises concerns under Guideline H. As of early 2026, marijuana remains a Schedule I controlled substance under federal law, and use is disqualifying regardless of state legalization. A December 2025 executive order directed the Attorney General to begin reclassifying marijuana to Schedule III, but that process isn’t complete, and reclassification wouldn’t eliminate marijuana as a security concern. Misusing any substance, prescription or otherwise, in a way inconsistent with its intended purpose raises reliability and judgment questions.1Office of the Director of National Intelligence. SEAD 4 – National Security Adjudicative Guidelines Individual agencies and contractors may also have their own marijuana policies, and violating those creates a separate concern.
Past use isn’t automatically fatal. Adjudicators look at recency, frequency, circumstances, and whether you’ve shown clear intent not to use again. Experimental marijuana use in college several years ago is treated very differently from regular use in the months before your application. What usually is fatal: lying about drug use on the SF-86. That’s worse than almost any use you’d be trying to hide.
Personal Conduct and Dishonesty
Guideline E covers personal conduct, and dishonesty during the application itself is one of the fastest routes to denial. Deliberately omitting or falsifying information on the SF-86 signals exactly the untrustworthiness the process is designed to catch. Adjudicators expect imperfect backgrounds. They don’t expect deception.
Foreign Influence and Preference
Close relationships with foreign nationals, financial interests abroad, or holding foreign citizenship raise concerns under Guidelines B and C. The worry is that these ties could be exploited by a foreign intelligence service to pressure you into compromising classified information. A foreign-born spouse or relatives abroad don’t automatically disqualify you, but they trigger closer scrutiny, especially when the country involved is treated as a heightened intelligence threat.
Everything Else
Criminal conduct, alcohol-related incidents, and psychological conditions that impair judgment or reliability fill out the rest of the commonly cited guidelines. Adjudicators also consider prior mishandling of protected information and outside activities that could create conflicts of interest.
The Polygraph
At some intelligence community agencies, the polygraph is part of the process. A clearance cannot be denied solely on a polygraph result, and SEAD 4 states explicitly that no adverse action may be taken based only on polygraph technical calls without other adjudicatively significant information. But information disclosed during the exam absolutely can support a denial. That is the point of the exam: to surface what records checks miss.
What Happens If You’re Denied
A denial comes with a Statement of Reasons identifying the specific guidelines and concerns behind the decision. Response deadlines vary by program. DoD Directive 5220.6 gives applicants in the DOHA industrial security program 20 days from receipt of the SOR to respond. DoD Manual 5200.02, covering military and civilian DoD employees, allows 30 calendar days with a possible 30-day extension. Intelligence community agencies operating under ICPG 704.3 allow 45 days. Other agencies set their own.
Your response can include a written rebuttal, mitigating evidence, and supporting documentation. For defense contractors, the process runs through the Defense Office of Hearings and Appeals under DoD Directive 5220.6. DOHA’s industrial security program handles contractor cases for DoD and more than 30 other federal agencies under the National Industrial Security Program.2Defense Office of Hearings and Appeals. Overview of DOHAs Industrial Security Mission You can request a hearing before a DOHA administrative judge, present witnesses and evidence, and appeal the judge’s decision to the DOHA Appeal Board.3Defense Office of Hearings and Appeals. DOHA Appeal Board Decisions
Military personnel and civilian DoD employees follow a different track. DOHA still conducts personal appearance hearings for them, but the administrative judge issues a recommendation rather than a final decision. That recommendation goes to the Personnel Security Appeals Board, which makes the final call.4Defense Counterintelligence and Security Agency.

Reapplying
No universal waiting period governs reapplication. Timing depends on which guideline was cited, why the denial happened, and whether you can demonstrate real change. Time alone rarely suffices. Adjudicators want evidence the underlying problem is resolved, not just months on the calendar. For financial issues, that means a track record of paying down debt and filing taxes. For drug involvement, sustained abstinence and lifestyle changes.
What a Denial Means for Your Job
Losing or being denied a clearance doesn’t automatically cost you your federal job. Your agency may reassign you to a role that doesn’t require access, though in many defense and intelligence positions that simply isn’t possible. For contractors, denial often means termination because the contract itself requires cleared personnel. The clearance determination and the employment decision are technically separate, even when they’re linked in practice.
A denial at one agency also doesn’t formally bar you from being cleared elsewhere, but it becomes part of your record. Any gaining agency will review the prior adjudication and the reasons behind it. Different agencies can reach different conclusions when the underlying concerns have been resolved, though as a practical matter it’s an uphill path.
