The cost of a public trust clearance to you is zero for the investigation itself. The hiring federal agency or contractor pays the Defense Counterintelligence and Security Agency (DCSA) to run the background check, and there is no application fee for the applicant.1Defense Counterintelligence and Security Agency. Federal Investigations Notice 24-01 – FY25 and FY26 Billing Rates What can cost you is everything around it: fingerprinting fees, certified documents, unpaid time waiting for the investigation to finish, and, in the worst case, legal help if the determination goes against you.
Why the Investigation Itself Is Free to You
Federal regulations put the bill on the requesting agency. DCSA will not open a case without a funded interagency agreement in place, and it can reject requests that arrive without funding documents.1Defense Counterintelligence and Security Agency. Federal Investigations Notice 24-01 – FY25 and FY26 Billing Rates If you are being hired as a contractor, the company absorbs the investigation cost as part of its contract price. Either way, no invoice reaches you.
For context, the government’s own cost for FY2026 runs from $197 for a low-risk Tier 1 investigation to $455 for a moderate-risk Tier 2 public trust check and $4,460 for a high-risk Tier 4 investigation.1Defense Counterintelligence and Security Agency. Federal Investigations Notice 24-01 – FY25 and FY26 Billing Rates Those numbers are useful to know only so you can recognize what a scam looks like. If someone claiming to represent a federal agency asks you to pay for your own background investigation, walk away. Legitimate federal hiring does not charge applicants for the investigation.
The Indirect Costs You Actually Pay
The investigation is free, but a handful of small expenses sit around the edges of the process.
Fingerprinting
Fingerprints are standard. Some agencies collect them in-house at no charge. Others send you to a third-party vendor for digital live scan prints, where fees typically run from $10 to $50. Ask the hiring agency what they want before you book anything, because paying out of pocket at the wrong vendor is a common and avoidable mistake.
Certified Documents
You will complete Standard Form 85P, the questionnaire for public trust positions, through the e-QIP electronic system.2U.S. Office of Personnel Management. Questionnaire for Public Trust Positions SF 85P and Supplemental The form asks about your employment history, residences, education, financial record, and any criminal history.3U.S. Office of Personnel Management. Questionnaire for Public Trust Positions Standard Form 85P Answering accurately sometimes means ordering certified copies of birth certificates, marriage licenses, court records, or military discharge paperwork. Fees vary by jurisdiction, generally from a few dollars up to around $40 per document.
Travel and Time Off
Higher-tier investigations may include an in-person interview, and travel to it is not always reimbursed. If you are still working somewhere else while the investigation runs, taking time off for appointments and interviews is a cost you absorb yourself.
The Biggest Hidden Cost: Waiting
The single largest financial impact for most applicants is the gap between your last paycheck at your old job and your first paycheck at the new one. You generally cannot start (and cannot start earning) until the investigation reaches at least a preliminary favorable status. Timelines vary sharply by risk level:
- Low-risk investigations: roughly one to three months
- Moderate-risk Tier 2: roughly three to six months
- High-risk Tier 4: six months to over a year
Some agencies grant interim favorable determinations that let you start work provisionally while the full investigation continues, but whether that option exists depends on the agency and the position. If you are leaving another job for a public trust role, plan for the possibility of a long unpaid stretch. A six-month gap can do more damage to your finances than every other cost in this process combined.
The Worst-Case Cost: Legal Help After an Unfavorable Determination
Most investigations end favorably and most applicants never need an attorney. If yours does not, this is where real money changes hands. Under 5 CFR Part 731, an unfavorable suitability action can include cancellation of eligibility or removal, and you generally have the right to respond before a final decision.4eCFR. 5 CFR Part 731 – Suitability and Fitness
Attorneys who handle federal suitability cases commonly charge $500 or more per hour. Flat-fee arrangements for responding to a formal notice or preparing for a hearing typically run from $3,500 to $7,500 or higher, depending on the stage of the case. Legal representation is the one expense in the whole public trust process that comes entirely out of your pocket.
One way to lower the odds of getting there: if you have unresolved debts, delinquent taxes, judgments, or a bankruptcy in your history, start addressing them before you apply. The SF-85P asks about all of it.3U.S. Office of Personnel Management. Questionnaire for Public Trust Positions Standard Form 85P No specific dollar figure is automatically disqualifying, but a pattern of financial trouble, especially for a role with access to financial systems, can lead to an unfavorable determination. A repayment plan already in place looks far better than an unexplained delinquency.
If You Already Have a Clearance
Executive Order 13488 generally requires a new federal employer to honor your existing favorable public trust determination, as long as the new role does not require a higher level of investigation, no new disqualifying information has come up, and you have had no break in federal employment.5GovInfo. Executive Order 13488 – Granting Reciprocity on Excepted Service and Contractor Employees Reciprocity spares you another SF-85P and another months-long wait.
The exception is when the new position carries a higher risk designation. Moving from a Tier 2 moderate-risk role to a Tier 4 high-risk role means starting the full process again, with the longer timeline and deeper scrutiny that goes with it, and with the same indirect costs to absorb a second time.
