The Internal Revenue Service handles tax returns, Social Security numbers, bank account information and other sensitive financial data for most of the country. Before anyone sits down at an IRS desk, whether as a contact representative, a revenue agent, an IT specialist or a seasonal filing season clerk, the agency runs them through a background screening process built on federal suitability law rather than a simple criminal records pull. This article explains what that process generally includes, where the tax compliance piece fits, how public trust risk levels work, and what tends to raise a flag.
Reveal Background is a consumer reporting agency that performs employment and tenant background checks for private employers. We are not the IRS and we do not conduct federal suitability or security clearance investigations. This article is written for IRS applicants and for employers who want to understand how federal hiring screening differs from a commercial background check.
The hiring sequence the IRS describes
According to the IRS Careers hiring process page, once a candidate receives a tentative job offer, the next step is a fingerprinting appointment at an approved site. After fingerprinting, the agency states that it “will initiate a preliminary background check, tax compliance check, and investigate any previous conduct issues,” and it refers to this combined review as a suitability check. Only after a favorable result does the agency issue a firm job offer with a start date and position details.
That sequence tells applicants two useful things. First, the tax compliance check is treated as its own distinct step, separate from the fingerprint based criminal history search and separate from the general conduct review. Second, the suitability check happens between the tentative offer and the firm offer, so a problem found during this window can affect whether the firm offer is extended at all.
What a tax compliance check is actually looking at
The IRS Careers site does not publish the exact mechanics of its internal tax compliance review, so this article will not guess at specifics the agency has not made public. What is documented is the underlying federal rule that makes a tax compliance check possible in the first place. Under the Office of Personnel Management suitability regulation at 5 CFR Part 731, one of the specific factors an agency may consider in a suitability determination is “failure to comply with financial obligations or generally applicable civil legal obligations, such as timely filing of tax returns.” That language is written into the general suitability rule that applies across the federal government, and it is the legal basis an agency such as the IRS can rely on when it reviews whether an applicant or employee has filed and paid their own taxes.
For an agency whose mission is tax administration, an employee who has not filed their own returns on time presents an obvious integrity concern, separate from whether that person has ever been charged with a crime. Employers outside the federal government generally cannot run a parallel check on a job applicant’s personal tax filing history, since that information is not part of a standard consumer background report and is protected by federal tax confidentiality law.
Suitability factors under 5 CFR Part 731
The suitability regulation lists the factors OPM and agencies may weigh when deciding whether someone is suitable for federal employment. The table below summarizes the factors found at 731.202.
| Suitability factor | What it generally covers |
|---|---|
| Misconduct or negligence in employment | Theft or misuse of government property, or failing to honor nondisclosure obligations tied to federal employment |
| Criminal conduct | Any criminal conduct, weighed along with its nature, seriousness, circumstances and how recent it was |
| Material false statement, deception or fraud | Lying, concealing information or committing fraud during the application or examination process |
| Dishonest conduct | General dishonesty not already captured by the other factors |
| Failure to meet financial or civil legal obligations | Includes the timely filing of tax returns, the regulatory hook for a tax compliance review |
| Excessive alcohol use | Considered when there is no evidence of rehabilitation and it could affect job performance or safety |
| Illegal use of controlled substances | Considered when there is no evidence of rehabilitation |
| Violent conduct | Weighed as its own factor separate from criminal conduct generally |
| A statutory or regulatory bar on employment | Examples given in the rule include citizenship or nationality requirements for the position |
That last line matters for the citizenship question many applicants ask. The suitability rule itself lists “citizenship or nationality requirements” as an example of a legal bar that can prevent lawful employment in a given position, and the rule separately allows an agency to inquire into an applicant’s citizenship status, Selective Service registration, military service or prior work history before extending a conditional offer. Most competitive service positions, including the large majority of IRS jobs, require United States citizenship, though the specific requirement and any exceptions depend on the position and the hiring authority used, so applicants should confirm citizenship eligibility against the individual job announcement rather than assuming a blanket rule.
Public trust and position risk levels
Most IRS jobs are not national security positions, but nearly all of them involve access to federally protected tax information, so they are generally designated at a moderate or high public trust risk level rather than a low risk, non sensitive level. The OPM Position Designation Tool, built jointly with the Defense Counterintelligence and Security Agency, is the standard federal method for assigning that designation. It separates two dimensions: a national security sensitivity level (non critical sensitive, critical sensitive or special sensitive) and a public trust risk level (low, moderate or high). A critical sensitive or special sensitive national security designation automatically carries a high risk public trust designation, and a noncritical sensitive designation automatically carries at least a moderate risk designation, unless the position’s duties call for something higher.
In everyday federal hiring language, these risk levels are often shorthanded as investigative tiers, with a moderate risk public trust review commonly referred to as a Tier 2 investigation and a high risk public trust review commonly referred to as a Tier 4 investigation. The tier label is informal shorthand used across agencies rather than a term defined in the position designation regulation itself, and the actual designation of a specific IRS position, and the investigation it requires, is set by the position’s own duties and access level, not by the label alone.
Credit and financial review
Because factor five of the suitability rule covers financial and civil legal obligations, a credit based review can be part of a federal suitability investigation, particularly for positions with access to financial systems, procurement authority or taxpayer accounts. The suitability regulation also addresses timing: agencies may make inquiries into an applicant’s Selective Service registration, military service, citizenship status or prior work history before a conditional offer, and the rule separately restricts when a full credit inquiry can be made, generally requiring a conditional offer first unless an exception applies under the related hiring regulations. This mirrors the sequencing consumer employers already know from the Fair Credit Reporting Act, where consent and disclosure come before adverse use of a report, though the federal suitability process runs under its own regulation rather than the FCRA.
Seasonal and temporary IRS staff
The IRS regularly brings on temporary and seasonal workers, particularly for filing season processing and taxpayer assistance roles. The IRS Careers page describing student and temporary appointments confirms that some positions are purely temporary, expected to last less than a year, without eligibility to convert to a permanent competitive service role. Nothing in the agency’s published hiring process suggests that temporary or seasonal status removes the fingerprinting, tax compliance and suitability review described above. Anyone handling taxpayer data, even for a short assignment, is working in a position that the agency has to designate and screen like any other.
Why oversight of IRS employee access matters
Suitability screening at hiring is only one layer. The Treasury Inspector General for Tax Administration provides independent oversight of the IRS, including its program for detecting unauthorized access to taxpayer accounts, sometimes referred to inside the agency as UNAX. A TIGTA audit report on the IRS unauthorized access program looked at how well the agency’s internal controls detect employees who look up or use taxpayer information outside their job duties, which is a separate and ongoing safeguard that exists precisely because employees who pass an initial background check still have broad access to sensitive records once hired.
What can disqualify an applicant
Based on the suitability factors above, an applicant may be found unsuitable, or an existing employee may face a suitability action, for reasons that generally fall into a few categories: criminal conduct weighed against its nature and how recent it was, dishonesty or false statements made during the application process, failure to meet financial obligations including the applicant’s own tax filing history, substance use without evidence of rehabilitation, violent conduct, or a legal bar such as a citizenship requirement the applicant does not meet. OPM and agencies are directed to weigh additional context, including how long ago the conduct occurred, the person’s age at the time, and evidence of rehabilitation, so a single past issue does not automatically mean a lifetime bar. Because these are case by case determinations made under federal regulation, applicants with a specific concern about an open balance with the IRS, a past conviction or a citizenship question should review the individual job announcement and may want to speak with the hiring agency directly rather than assume an outcome.
Frequently asked questions
Does the IRS run a credit check on every applicant?
A financial review may be part of the suitability process for positions where it is job related, since the suitability regulation lists failure to meet financial obligations as one of the factors an agency may weigh. Whether a full credit report is pulled, and when, depends on the position and generally follows a conditional job offer.
Can someone who owes back taxes still be hired by the IRS?
Not necessarily disqualifying on its own. The suitability rule treats failure to meet financial obligations, including timely tax filing, as one factor among several, and the agency also weighs the nature, recency and circumstances of the issue. An unresolved or undisclosed tax compliance problem is more likely to be a concern than a resolved one that was disclosed honestly.
Do seasonal or temporary IRS employees go through a background check?
The published hiring process describes fingerprinting, a tax compliance check and a conduct review as part of reaching a firm job offer, and nothing in IRS Careers materials exempts temporary or seasonal appointments from that process. Anyone with access to taxpayer information is screened and designated like any other position.
Is United States citizenship required for IRS jobs?
Most competitive federal positions, including most IRS roles, require citizenship, and federal suitability regulation specifically lists citizenship or nationality requirements as an example of a legal bar to employment in a given position. Exceptions and specific requirements vary by job announcement, so applicants should confirm the citizenship requirement listed for the specific position.
How long does the IRS suitability review usually take?
The agency’s own hiring process page describes the preliminary background, tax compliance and conduct review together as the suitability check, and states it normally spans a few weeks once fingerprinting is complete. Actual timing can vary by position and caseload.
Does screening stop once someone is hired?
No. Independent oversight continues after hiring, including monitoring for unauthorized access to taxpayer accounts, and OPM regulation also allows suitability actions against current employees, not only applicants, when a covered factor arises during employment.
For comparison, two other federal roles follow a similar public trust screening model: our census worker background check overview and our TSA officer background check requirements guide both walk through federal suitability screening for different agencies.
