How Much Does a Security Clearance Cost and Who Pays It?

A U.S. security clearance costs you nothing out of pocket. The sponsoring federal agency or cleared contractor pays for the background investigation, and in fiscal year 2026 that bill ranges from $197 for the lowest tier of vetting up to $6,240 for a Department of Defense Top Secret investigation with adjudication bundled in.¹ You cannot start the process on your own, and no legitimate clearance process will ever ask you to pay a fee.

The Actual Price Tags

The Defense Counterintelligence and Security Agency publishes its billing rates each fiscal year. These are what the sponsoring agency pays, not what you pay. For FY 2026, the standard rates charged to non-DoD agencies are:¹

Tier 1, low-risk positions: $197
Tier 3, Secret clearance: $455
Tier 5, Top Secret clearance: $5,890
Tier 5 reinvestigation: $3,230

Department of Defense agencies pay higher rates because their investigations now include adjudication services inside the price. A DoD Tier 5 investigation runs $6,240 at the standard rate and $6,739 for priority processing.¹ DCSA handles personnel vetting for the DoD and more than 100 other federal agencies, so these rates cover most of the federal clearance workload.²

The gap between $455 for Secret and $5,890 for Top Secret reflects scope. A Tier 3 investigation looks at a narrower set of records. A Tier 5 investigation digs into ten years of your life, with more extensive interviews, financial record reviews, and checks with references and former employers.³

Why You Can’t Pay for One Yourself

A common misconception is that you can go out and buy a clearance. You cannot. The State Department states plainly that applicants cannot initiate a security clearance application on their own and must have a conditional offer of employment for a position that requires one.⁴ The sponsoring agency or cleared contractor decides what level of investigation you need and submits the request to DCSA.⁵

From your side, the sequence goes: conditional job offer, employer submits the request, DCSA sends you an electronic questionnaire to fill out. If anyone asks you to pay upfront for a security clearance or offers to “pre-clear” you before a job offer, that’s a scam.

What You Might Actually Spend

You’ll never see a bill for the investigation. But some expenses land on you around the edges of the process:

Document retrieval. You may need certified copies of birth certificates, marriage certificates, academic transcripts, or similar records. Fees vary by jurisdiction but typically run $10 to $25 per document.
Travel. If the investigation requires an in-person interview away from your home or workplace, transportation and meals are on you. Most interviews happen at or near your work site, so this is uncommon.
Lost wages. Time spent in interviews or gathering documents during working hours can mean lost income for hourly workers.

These costs stay modest compared to the investigation itself. There’s no advance checklist of documents to buy; what you need depends on your personal history and what the investigator asks for.

The Time Cost

The heaviest cost most applicants feel isn’t money. It’s the wait. As of the third quarter of fiscal year 2025, the average end-to-end timeline for a background investigation was 243 days: 19 days to initiate, 215 to investigate, and 9 to adjudicate. That figure is pulled up by complex Top Secret cases. Tier 3 investigations for a Secret clearance moved considerably faster, averaging about 138 days total.⁶

Some employers let you start on unclassified work while your investigation runs. Others cannot bring you on until the clearance comes through. If you’re leaving an existing job to take a cleared position, that gap is real financial exposure worth planning for.

What Pushes the Investigation Bill Higher

Several factors add cost above the base rate. None of these come out of your pocket, but they explain why some employers are selective about which candidates they sponsor for higher-level clearances.

Foreign connections. Extensive international travel, foreign contacts, or time living abroad triggers an international coverage add-on of $990 per investigation.¹
Complicated personal history. Past financial difficulties, legal issues, or employment gaps may require additional interviews. A triggered enhanced subject interview alone adds $1,056.¹
Polygraph requirements. Certain agencies and positions, particularly in the intelligence community, require polygraph examinations on top of the standard investigation. These are funded separately by the requiring agency.
Sensitive Compartmented Information access. SCI access goes beyond a standard Top Secret clearance and involves additional vetting by the sponsoring intelligence agency.

A company bidding on a government contract has to budget for these investigation costs, so a candidate with a complicated file is a more expensive bet for the sponsor.

Costs If Your Clearance Is Denied

A denial is the point where costs can shift directly to you. The investigation and initial adjudication are still paid for by the government. Fighting a denial is your financial responsibility. Through the Department of Defense, you can appeal a denial or revocation in writing to your component’s Personnel Security Appeals Board, or you can elect a personal appearance hearing before a Defense Office of Hearings and Appeals administrative judge. The DOHA judge makes a recommendation, and the PSAB uses it in making the final determination.⁷

A written appeal costs little beyond your time. Hiring a security clearance attorney is different. Legal fees can run from a few thousand dollars for straightforward cases into the tens of thousands for complex ones involving multiple adjudicative guidelines. Add travel to the hearing location, costs of gathering supporting medical or financial documentation, and potentially expert opinions.

One thing worth knowing: these legal fees are not tax-deductible. The Tax Cuts and Jobs Act eliminated the miscellaneous itemized deduction that previously let employees deduct unreimbursed business expenses like employment-related legal fees. That suspension, originally set to expire at the end of 2025, was made permanent by the One Big Beautiful Bill Act.⁸

Facility Clearances Are a Separate Cost Picture

If you’re asking about clearance costs on behalf of a business rather than yourself, the numbers look different. Companies that work on classified contracts need a facility security clearance in addition to individual clearances for their employees. The government funds the FCL application and processing at no charge to the contractor.⁹

The real cost is the physical infrastructure. If a contract requires a Sensitive Compartmented Information Facility, construction runs anywhere from $350 to $1,000 per square foot depending on the security specifications.¹⁰ Even without a full SCIF, companies need GSA-approved security containers for storing classified documents, and shipping alone runs $400 to $1,500 depending on delivery method and location.¹¹ Companies also need a Facility Security Officer to manage the clearance program and act as the primary point of contact with DCSA. For smaller contractors, that’s often a part-time role added to existing duties. Larger defense contractors employ full-time security teams, and those staffing costs are typically built into contract bids.
