An 1811 special agent is a federal criminal investigator, hired under a job series code assigned by the Office of Personnel Management, who enforces federal law by carrying a firearm, executing warrants, making arrests, and building cases for federal prosecution. The classification covers agents at dozens of agencies, from the FBI, DEA, Secret Service, and U.S. Marshals to the IRS Criminal Investigation division and the inspector general offices spread across the government. Their jurisdiction is federal offenses only, not the traffic stops, burglaries, and state-level crimes that occupy local police.
What the 1811 Series Covers
The Office of Personnel Management assigns four-digit codes to every type of federal job. The 1811 series sits within the 1800 family of investigation and inspection positions, but at the top of it in terms of authority. The public calls these employees “special agents.” The government’s official title is Criminal Investigator.
That distinction separates 1811 from two nearby series people often confuse it with. The 0083 series covers uniformed federal police who handle patrol and access control at government buildings. The 1801 series covers general inspection and compliance work that rarely produces criminal charges. Only the 1811 classification carries the full package of law enforcement retirement, availability pay, and statutory authority to carry a firearm and arrest.
Which Agencies Hire 1811 Agents
The two largest employers are the Department of Justice and the Department of Homeland Security. Inside Justice, the FBI has the biggest force, followed by the Drug Enforcement Administration, the Bureau of Alcohol, Tobacco, Firearms and Explosives, and the U.S. Marshals Service. On the Homeland Security side, Homeland Security Investigations and the Secret Service each employ thousands of criminal investigators. Treasury’s IRS Criminal Investigation division pursues tax fraud and financial crime.
Beyond the well-known agencies, nearly every federal department has an Office of Inspector General staffed with 1811 agents. OIG investigators focus on fraud, waste, and abuse inside their parent agency’s programs. An OIG agent at Health and Human Services, for example, investigates Medicare fraud rather than drug trafficking. When OIG investigators find evidence of broader federal crimes, they refer those matters to the Attorney General for prosecution.1Office of the Law Revision Counsel. Inspector General Act of 1978
What the Job Involves Day to Day
The daily work looks nothing like television. A significant part of every agent’s week is spent writing detailed reports documenting each interview, search, and piece of evidence. Federal prosecutors depend on those reports to bring cases to a grand jury, and sloppy paperwork can sink an otherwise solid investigation.
The investigative work itself varies by agency but shares common elements: surveillance, undercover operations, witness interviews, and suspect interrogations. Agents manage physical evidence and maintain a documented chain of custody so nothing gets thrown out at trial. When a case is ready, they work directly with Assistant U.S. Attorneys to prepare for court and often testify before grand juries and at trial.
Task Force Work
Federal investigations frequently cross agency lines, so 1811 agents routinely work joint task forces alongside state and local officers. The FBI alone runs about 200 Joint Terrorism Task Forces, with at least one in each of its 56 field offices, pulling investigators and analysts from dozens of agencies into a single team.2FBI. Joint Terrorism Task Forces Similar multi-agency structures exist for organized crime, narcotics, financial fraud, and cybercrime.
Legal Authority and Its Limits
Federal criminal investigators can carry firearms on and off duty, execute search warrants issued by federal judges, and arrest anyone they have probable cause to believe has committed a federal crime. That authority reaches across all 50 states and U.S. territories, a geographic span no local department can match.
The specific source of arrest authority differs by agency. FBI agents rely on one set of statutes, DEA agents on another. The common thread is that 1811 agents act under federal authority and the Fourth Amendment’s requirements for searches and seizures. Their jurisdiction is limited to federal offenses. State-level crimes belong to state and local police.
Who Qualifies
Getting hired is competitive. The requirements filter out most applicants well before an academy.
Education and Experience
Most agencies hire entry-level agents at GL-5, GL-7, or GL-9. At GL-5, a bachelor’s degree in any field generally qualifies, though relevant investigative or law enforcement experience can substitute depending on the job announcement.3U.S. Office of Personnel Management. Criminal Investigator Treasury Enforcement Agent 1811 Higher entry grades require graduate education or specialized experience. IRS Criminal Investigation is an outlier: its agents need at least 15 semester hours of accounting plus coursework in finance, economics, or tax law.
Age Limits
Federal law forces 1811 agents into mandatory retirement no later than age 57, extendable to 60 at the agency head’s discretion, once they have completed 20 years of law enforcement service.4Office of the Law Revision Counsel. 5 USC 8425 – Mandatory Separation Because of that ceiling, new agents generally must be appointed before their 37th birthday so they can reach the 20-year mark. Some agencies grant waivers for prior qualifying federal law enforcement experience, and veterans may receive age adjustments for military service.
Background Investigation
Every 1811 candidate goes through an extensive background investigation for a Top Secret security clearance. Some agencies, including the FBI, require the more restrictive Top Secret/SCI level. Investigators review financial history, criminal record, drug use, and personal character, and they interview neighbors, former employers, coworkers, and references going back years. For the FBI, the process includes a polygraph, a personnel security interview, drug testing, and fingerprinting. The average investigation takes about six months and can stretch beyond 18 months depending on where you’ve lived, worked, and traveled.5FBIJOBS. Special Agent Application and Evaluation Process
Physical and Medical Standards
You have to pass a physical fitness test and a thorough medical evaluation. Fitness tests vary by agency but typically include timed runs, push-ups, sit-ups, and pull-ups. Medical standards are strict. Many agencies require corrected distance vision of 20/20 in each eye, and if you wear glasses rather than contacts, your uncorrected vision must meet minimum thresholds too, though the exact numbers differ by agency.6ICE.gov. Medical FAQs for ICE LE Applicants Hearing, cardiovascular health, and other conditions are also evaluated.
Legal Disqualifiers
Certain convictions permanently bar you from the 1811 series. The most notable is any misdemeanor crime of domestic violence. Under federal law, anyone with that conviction is prohibited from possessing a firearm, and there is no law enforcement exception.7Department of Justice Archives. Restrictions on the Possession of Firearms by Individuals Convicted of a Misdemeanor Crime of Domestic Violence Because carrying a firearm is a core function, a qualifying domestic violence conviction makes it legally impossible to serve. Felony convictions and certain drug use histories also disqualify.
Mobility
Most agencies require new agents to sign a mobility agreement, meaning you accept reassignment to any office in the country as a condition of employment. You may list geographic preferences, but the agency decides based on staffing needs.8FBI Jobs. Special Agent FAQ Transfers later in your career, sometimes involuntary, are also possible. If you’re unwilling to relocate, this career will be a poor fit.
How Hiring and Training Work
The road from application to academy typically takes a year or more. Each agency runs its own version, but the pattern is consistent: written application and federal resume, a proctored exam covering logic, reasoning, situational judgment, and personality, a physical fitness test, further testing, and a panel interview with agent assessors.5FBIJOBS. Special Agent Application and Evaluation Process Clearing those stages produces a conditional offer. The word conditional matters: your background investigation, polygraph, medical exam, and a final physical fitness test all have to come back clean before you report to training. Any one can end the process.
New 1811 agents attend one of two training pipelines. The FBI and DEA run their own academies. FBI new agent training runs approximately 18 weeks at Quantico, Virginia, covering more than 800 hours of academics, case exercises, firearms, and operational skills.9Federal Bureau of Investigation. Training
Most other agencies send their new agents to the Federal Law Enforcement Training Centers, with the primary campus in Glynco, Georgia. There, agents complete the Criminal Investigator Training Program, 59 training days covering interviewing, investigative operations, firearms, legal instruction, and defensive tactics.10Federal Law Enforcement Training Centers. Criminal Investigator Training Program After CITP, agents return to their hiring agency for specialized training tied to that agency’s mission. Failing to meet standards on the range, in academics, or on fitness tests results in dismissal.
Pay and Compensation
Compensation is more generous than the base General Schedule numbers suggest, because several pay enhancements stack.
Base Salary and Grade Levels
New agents typically enter at GL-5, GL-7, or GL-9 depending on education and experience. GL stands for General Law Enforcement and mirrors the standard GS pay table. In 2026, base salaries at step 1 start at $34,799 for GL-5, $43,106 for GL-7, and $52,727 for GL-9. Agents advance through a career ladder up to GS-13, where 2026 base pay ranges from $90,925 to $118,204 depending on step.11U.S. Office of Personnel Management. Salary Table 2026-GS Career-ladder promotions are performance-based and require supervisory approval but are non-competitive, so you don’t apply against outside candidates.12US EPA. Special Agent Salary and Benefits
Law Enforcement Availability Pay
On top of base salary, most 1811 agents receive Law Enforcement Availability Pay, or LEAP, a flat 25% increase. In exchange, agents must average at least two additional hours of unscheduled work per day beyond the standard schedule, reflecting the reality that criminal investigations don’t stop at 5 p.m.13Office of the Law Revision Counsel. 5 USC 5545a – Availability Pay for Criminal Investigators LEAP is not optional overtime; it’s a condition of employment for most 1811 positions.
Locality Pay
Federal employees in higher-cost areas receive a locality adjustment. In 2026, these adjustments range from 17.06% to 46.34% across 58 locality pay areas.14Federal Register. January 2026 Pay Schedules Because LEAP is calculated on top of locality-adjusted pay, agents in Washington, D.C., New York, or San Francisco see significantly higher total pay than the base table alone suggests.
What That Adds Up To
A GS-13 step 1 agent in a moderate locality area, say 25%, earns roughly $90,925 base plus $22,731 locality, for about $113,656 in adjusted salary. Add 25% LEAP and total pay reaches approximately $142,070 before any overtime. A journeyman agent in a high-cost city can earn well over $150,000.
Retirement Benefits
The retirement package is substantially better than what general federal employees receive, and it’s one of the biggest financial advantages of the career.
Early Retirement
Unlike most federal workers, law enforcement officers under FERS can retire at age 50 with 20 years of covered service, or at any age after completing 25 years of law enforcement service. This early eligibility is the trade-off for mandatory retirement at 57.
Enhanced Annuity Formula
The FERS calculation for law enforcement uses a more generous multiplier. The first 20 years earn 1.7% of high-three average salary per year. Years beyond 20 earn 1%.15U.S. Office of Personnel Management. Computation A standard federal employee earns only 1% per year, or 1.1% if retiring at 62 or later with 20+ years. An agent retiring at 50 with exactly 20 years and a high-three average of $140,000 would draw an annuity of $47,600, roughly 34% of salary. Five more years lifts that to $54,600.
Special Retirement Supplement
Agents who retire before 62 also receive a Special Retirement Supplement bridging the gap until Social Security begins. It approximates what Social Security would pay for the years of federal law enforcement service and runs until the retiree turns 62 or becomes eligible for actual Social Security, whichever comes first.16Office of Personnel Management. Information for FERS Annuitants RI 90-8 Law enforcement retirees also receive annual cost-of-living adjustments to their annuity before age 62, which general FERS retirees under 62 do not.
