Federal overtime and premium pay are governed by a system that was designed for a different era of federal work. Title 5 overtime rules date to the early 20th century. The Fair Labor Standards Act, originally passed in 1938, was extended to federal employees in 1974. The two frameworks were never fully reconciled — instead, Congress layered them, creating a split that persists today. Nonexempt employees get FLSA overtime; exempt employees get Title 5 overtime. They are not the same. The hourly rate can differ. The caps differ. The interaction with premium pay differs. The tax treatment, starting with 2025 returns, now differs as well.
For most federal employees, overtime is a small fraction of total compensation and the mechanics rarely come into sharp focus. For employees in positions that regularly involve overtime — emergency management, law enforcement, IT operations, field engineering, any role with surge requirements — the rules determine thousands of dollars of annual pay and determine whether the employee accepts cash, accepts comp time, or declines the overtime. This guide covers the framework for both populations and the specific situations where the rules produce non-obvious results.
FLSA status is not a matter of rank or salary — it is a matter of duties. A GS-7 administrative assistant and a GS-14 cybersecurity specialist can both be FLSA-nonexempt if their actual duties do not meet the exemption tests. Agencies determine status based on the position description under 5 CFR Part 551, and the determination appears on the SF-50. Employees who assume "high grade equals exempt" miss the range of nonexempt positions at GS-13 and GS-14. Employees who assume exemption means higher overtime pay routinely discover the GS-10 step 1 cap reduces their overtime rate below what a GS-10 nonexempt employee earns. Read your SF-50. The rest of this guide flows from that one code.
Section I FLSA-exempt vs. nonexempt
The Fair Labor Standards Act — 29 U.S.C. 201 et seq. — sets minimum wage and overtime requirements for covered workers. Federal employees were brought under the FLSA by 1974 amendments. Not all federal employees are covered; exemptions apply to employees whose duties meet specific tests.
How status is determined
Under 5 CFR Part 551, agency HR offices determine FLSA coverage based on the actual duties an employee performs, as documented in the position description. The three primary exemption categories — executive, administrative, and professional — each have specific duties tests. A position is exempt only if the duties meet the applicable test; salary level alone does not determine status. After the agency determines status, it is reflected on the SF-50 in Block 35 as E (exempt) or N (nonexempt).
What each status means for overtime
FLSA-nonexempt employees are covered by 29 U.S.C. 207 and receive overtime at 1.5 times their regular rate for hours worked over 40 in a workweek. The regular rate includes most premium pays but excludes certain exclusions specified in the FLSA. Agencies must pay nonexempt employees for work "suffered or permitted" — meaning the agency allowed the employee to work, even without an explicit overtime order.
FLSA-exempt employees are not covered by FLSA overtime provisions. They may be eligible for overtime under Title 5 (5 U.S.C. 5542), which operates under different rules including the GS-10 step 1 cap. Title 5 overtime requires that work be "officially ordered or approved" — the agency-permitted standard does not apply.
Who is not eligible for any overtime
Certain categories of federal employees are excluded from overtime entirely. Members of the Senior Executive Service do not receive overtime — their compensation includes expectation of the full workload. Certain other senior positions may be excluded based on 5 U.S.C. 5541 definitions. Some categories of firefighters have special rules under 5 U.S.C. 5545b with different hour thresholds (53 hours per week or 106 hours biweekly).
Checking your status
Pull your most recent SF-50 from your eOPF. Find Block 35 (FLSA Category) and confirm whether you are coded E or N. If the status seems incorrect — for example, an employee whose duties clearly do not meet an exemption test is coded E — the employee can request an FLSA exemption status determination from OPM. FLSA claims are subject to a two-year statute of limitations (three years for willful violations) and should be filed with the Classification Appeals and FLSA Claims Program Manager at OPM, Room 6484, 1900 E Street NW, Washington, DC.
Section II Title 5 overtime and the GS-10 cap
Title 5 overtime under 5 U.S.C. 5542 covers FLSA-exempt employees. The calculation is simpler than FLSA overtime but subject to a cap that reduces the effective rate for higher-grade employees.
When Title 5 overtime applies
5 U.S.C. 5542 authorizes overtime pay for hours of work officially ordered or approved in excess of applicable overtime standards — generally 8 hours in a day or 40 hours in an administrative workweek. The work must be formally ordered or approved by the supervisor; suffered-or-permitted work is not covered. A minimum of 2 hours is paid for unscheduled overtime work requiring return to the workplace or work on a nonscheduled workday.
The basic calculation
For employees whose rate of basic pay is at or below GS-10 step 1 (including locality pay), the Title 5 overtime rate is 1.5 times the employee's own hourly rate of basic pay. A GS-7 exempt employee earning $50,000 base plus locality effectively earns overtime at 1.5x their actual rate.
The GS-10 step 1 cap
For employees whose rate of basic pay exceeds GS-10 step 1 (including locality), 5 U.S.C. 5542(a)(2) specifies that the overtime hourly rate is the greater of: 1.5 times the GS-10 step 1 hourly rate (including locality and any applicable special rate), or the employee's own hourly rate of basic pay. This is the cap. A GS-13 or GS-14 exempt employee who works overtime receives the capped rate, not 1.5 times their higher hourly rate.
The 2003 amendment
Before 2003, higher-grade employees could earn less per overtime hour than their regular hourly rate — because 1.5 times GS-10 step 1 was sometimes less than the employee's own hourly rate. Section 1121 of the FY2004 NDAA amended 5 U.S.C. 5542(a)(2) to guarantee the employee at least their own hourly rate for overtime. Now the rate is the greater of the two figures, ensuring higher-grade employees are not penalized.
Practical effect
A GS-13 step 5 exempt employee in the Washington-Baltimore locality works 10 hours of approved overtime. Their hourly basic pay exceeds GS-10 step 1, so the overtime rate is the greater of 1.5 × GS-10 step 1 or their own hourly rate. In practice, the GS-10 step 1 × 1.5 calculation often produces an overtime rate that is higher than the employee's own hourly rate (because of the 1.5 multiplier) but significantly below what the employee would earn if they received 1.5 times their own rate. The cap effectively reduces the effective overtime premium for higher-grade exempt employees.
Section III FLSA overtime calculation
FLSA overtime under 29 U.S.C. 207 covers FLSA-nonexempt employees and operates without the Title 5 cap.
The 40-hour standard
FLSA requires overtime at 1.5 times the regular rate for hours worked over 40 in a workweek. The workweek is a fixed and regularly recurring period of 168 hours (seven consecutive 24-hour periods), not necessarily coincident with the calendar week. Averaging hours over two or more weeks is not permitted — overtime is calculated on each workweek independently.
The "regular rate"
FLSA overtime is calculated on the "regular rate," which is a broader concept than basic pay. The regular rate includes basic pay plus certain pays like night differentials, Sunday pay, and some premium pays. Specific exclusions are listed in the FLSA. OPM's "How to Compute FLSA Overtime Pay" fact sheet provides the detailed calculation methodology for federal nonexempt employees.
No Title 5 cap
FLSA overtime pay is not subject to the GS-10 step 1 cap. A nonexempt GS-13 earns FLSA overtime at 1.5 times their own regular rate. This produces the somewhat counterintuitive result that a nonexempt GS-13 may earn more per overtime hour than an exempt GS-13, despite identical grade and step.
Suffered or permitted work
FLSA-covered employees must be compensated for work that is "suffered or permitted" — meaning the agency allowed the employee to work even without an explicit overtime order. Supervisors cannot avoid overtime liability by declining to formally order work the employee is actually performing with supervisor knowledge. Title 5 overtime, by contrast, requires formal approval.
Minimum wage
FLSA also imposes minimum wage requirements. For federal employees, minimum wage is rarely a binding constraint — the lowest GS rates substantially exceed federal minimum wage — but the protection exists for certain categories of federal workers.
Section IV Premium pay and the biweekly cap
"Premium pay" is a Title 5 category that includes Title 5 overtime, night differential, Sunday pay, holiday premium, standby duty pay, administratively uncontrollable overtime (AUO), and availability pay for criminal investigators. It does not include FLSA overtime pay.
The biweekly cap
Under 5 U.S.C. 5547(a) and 5 CFR 550.105, premium pay cannot be paid to General Schedule employees to the extent it would cause the employee's basic pay, Title 5 overtime pay, dollar value of compensatory time off, night pay, annual premium pay, Sunday premium pay, and holiday premium pay to exceed, in any biweekly pay period, the greater of: the biweekly rate for GS-15 step 10 at the employee's locality (or applicable special rate), or the biweekly rate for Executive Schedule Level V.
What the cap does not limit
FLSA overtime pay and FLSA compensatory time off are excluded from the premium pay definition and are not subject to the biweekly or annual limitations. Nonexempt employees can earn FLSA overtime above the cap that would apply to exempt employees' Title 5 overtime. Compensatory time off for travel, religious comp time, credit hours, and hazardous duty pay are also excluded from the cap.
The annual cap exception
Under 5 U.S.C. 5547(b), for employees performing emergency work (as determined by the agency head or OPM) or mission-critical work (as determined by the agency head), premium pay may be capped annually rather than biweekly. The annual cap is the greater of: the annual rate for GS-15 step 10 at the employee's locality, or the annual rate for Executive Schedule Level V. This allows more concentrated overtime work during emergencies without employees hitting the biweekly cap mid-pay-period.
Special rules for specific premium pays
Standby duty pay under 5 U.S.C. 5545(c)(1), AUO pay under 5 U.S.C. 5545(c)(2), and availability pay for criminal investigators under 5 U.S.C. 5545a remain subject to biweekly limitation even when other premium pays are under the annual cap. These specific premium pays have detailed operational rules depending on the agency and position type.
Section V Compensatory time, credit hours, religious comp
Three commonly confused categories of accrued time off, each governed by different authorities.
Regular compensatory time off
5 U.S.C. 5543 authorizes compensatory time off in lieu of monetary overtime pay for FLSA-exempt employees. The agency may require irregular or occasional overtime to be taken as comp time rather than cash for employees whose rate of basic pay exceeds GS-10 step 1. Comp time is earned hour-for-hour at the overtime rate. The dollar value counts toward the biweekly premium pay cap — the number of comp time hours an employee may accrue in a pay period cannot exceed what they could have received as monetary overtime.
Comp time has a use-it-or-lose-it timeline: the employee must use accrued comp time by the end of the 26th pay period after the pay period in which it was earned, or the hours are forfeited. Agency policies may convert unused comp time to cash in specific circumstances, but the 26-pay-period window is the governing rule.
Credit hours under alternative work schedules
Credit hours under 5 U.S.C. 6121-6126 are fundamentally different from comp time. They are earned when an employee on a flexible work schedule works additional hours voluntarily, within the basic 80-hour biweekly requirement, to be used later as time off. Credit hours are not overtime, do not require approval as overtime, and do not count toward the premium pay cap. They are available only to employees on flexible work schedules (not to employees on compressed work schedules, which have fixed daily hours).
Credit hour caps: full-time employees can carry up to 24 credit hours at the end of a pay period; part-time employees have proportional limits. Credit hours cash out at the employee's current basic pay rate when the employee separates or changes schedules.
Religious compensatory time
5 U.S.C. 5550a authorizes religious compensatory time off — additional hours worked specifically to make up time taken off for religious observance. Unlike regular comp time, religious comp time does not expire. Unlike credit hours, religious comp time is tied to the specific purpose of religious accommodation rather than general schedule flexibility. The authority is separate from regular comp time and credit hours.
Compensatory time off for travel
Authorized by 5 U.S.C. 5550b, this is earned when an employee travels on non-work time for official duty. It is distinct from both regular comp time and religious comp time, has its own accrual and use rules, and is not counted in the premium pay biweekly cap calculation.
Section VI Night differential, Sunday, and holiday premium
Beyond overtime and comp time, several premium pay categories apply to specific timing of work.
Night differential
Under 5 U.S.C. 5545, night pay is a 10 percent differential for regularly scheduled work between 6:00 p.m. and 6:00 a.m. The differential applies to hours actually worked during the night period; it does not apply to the entire shift if only part of the shift falls within the night window. Night differential is part of basic pay for FLSA purposes (affecting the regular rate for FLSA overtime) but counts toward the premium pay biweekly cap for exempt employees.
Sunday premium
Under 5 U.S.C. 5546, Sunday premium is a 25 percent differential for regularly scheduled non-overtime work performed on Sunday. The premium applies to full-time employees whose regular schedule includes Sunday work; it does not apply to overtime work on Sunday (which is paid as overtime, not Sunday premium) or to part-time employees whose Sunday hours are not part of a regular schedule.
Holiday premium
Under 5 U.S.C. 5546(b), employees who perform work on a designated federal holiday receive holiday pay at 1.5 times their regular rate for non-overtime hours worked on the holiday (in addition to the regular pay they receive for the holiday itself). Holiday premium is separate from overtime — an employee working overtime on a holiday can receive both holiday pay and overtime pay, subject to the biweekly cap.
The detailed rules
The interactions between night differential, Sunday premium, holiday premium, overtime, and the biweekly cap are complex. Employees in positions with regular rotating shifts or on-call duties should request their agency's payroll office provide a written explanation of how premium pay is calculated for their specific work pattern. See our forthcoming guide on night differential, Sunday premium, and holiday pay for more detailed rules.
Section VII The 2025 OBBBA overtime tax deduction
A significant 2025 federal tax change affects how overtime compensation is treated for individual income tax purposes — adding a new layer for federal FLSA-nonexempt employees to understand.
The OBBBA provision
The One Big Beautiful Bill Act (OBBBA), P.L. 119-21, enacted in 2025, created a new individual income tax deduction for qualified overtime compensation. IRS Notice 2025-69 and subsequent guidance in IR-2026-10 provide the calculation methodology for tax year 2025. The deduction is available to individuals who meet eligibility criteria and received qualified overtime compensation during the tax year.
What qualifies as "qualified overtime compensation"
Qualified overtime compensation is the premium portion — the "half" in "one and one-half times" — of overtime pay required under section 7 of the Fair Labor Standards Act (29 U.S.C. 207). Only the FLSA-required premium portion qualifies; any amount paid beyond the FLSA requirement does not qualify. For example, if an employer pays double the regular rate for overtime, only the half-rate portion relied upon to comply with the FLSA requirement is qualified overtime compensation under OBBBA.
Who can claim the deduction
Federal FLSA-nonexempt employees who receive FLSA overtime compensation may be eligible for the deduction on their individual tax return. Federal FLSA-exempt employees receiving Title 5 overtime generally do not qualify under the statute, because Title 5 overtime is not FLSA-required overtime. Specific eligibility depends on the employee's filing status, income, and other factors not covered by this guide — consult IRS Notice 2025-69 and instructions to Schedule 1-A of Form 1040 for details.
Employer reporting
For tax years 2026 and later, employers (including federal agencies) are required to separately report qualified overtime compensation. Forms W-2, 1099-NEC, and 1099-MISC are being updated for this separate reporting. Federal employees should confirm their 2025 W-2 includes the information needed to calculate the deduction if they received FLSA overtime during the year.
Practical implications
The OBBBA deduction does not change the federal employee's paycheck — the overtime is still paid the same way. It changes the employee's tax return calculation. Federal nonexempt employees who worked significant FLSA overtime in 2025 or 2026 should consult their tax preparer or IRS guidance to ensure the deduction is properly claimed. The premium-only limitation is important: an employee who earned $3,000 of total FLSA overtime pay (1.5x the regular rate) has $1,000 of qualified overtime compensation (the 0.5x premium portion).
What to do this quarter
- Pull your most recent SF-50 and check Block 35. Confirm you are coded E (exempt) or N (nonexempt). If the status seems inconsistent with your actual duties, consult your HR office.
- If you are FLSA-exempt above GS-10 and regularly work overtime, calculate the effective overtime rate you are actually receiving. The GS-10 cap may be reducing your effective premium below 1.5x your hourly rate.
- If you accumulate regular comp time, track the 26-pay-period window and schedule usage before the forfeiture date. Agencies do not proactively remind employees.
- If you are FLSA-nonexempt and received FLSA overtime in 2025 or 2026, review IRS Notice 2025-69 and Schedule 1-A instructions to determine whether you can claim the OBBBA qualified overtime deduction.
- If your work regularly involves night, Sunday, or holiday hours, request a written premium pay calculation from your agency payroll office. The interactions with the biweekly cap can produce surprises.
Section VIII Frequently asked questions
FLSA exemption status is determined by the actual duties an employee performs, not by grade level alone. The agency's servicing HR office determines FLSA coverage based on 5 CFR Part 551 and the employee's position description. The status appears on the SF-50 in Block 35 as E (exempt) or N (nonexempt). FLSA-nonexempt employees are covered by the Fair Labor Standards Act and receive overtime at 1.5 times their regular rate of pay for hours worked over 40 in a workweek. FLSA-exempt employees are not covered by the FLSA but may be eligible for overtime under Title 5 of the U.S. Code, which operates under different rules and caps. The distinction affects every premium pay calculation.
Under 5 U.S.C. 5542(a)(2), for FLSA-exempt employees whose basic pay exceeds GS-10 step 1, the overtime hourly rate is the greater of one and one-half times the GS-10 step 1 hourly rate, or the employee's own hourly rate of basic pay. This effectively caps overtime compensation for higher-grade exempt employees at the GS-10 step 1 figure — meaning a GS-13 or GS-14 exempt employee earns overtime at a rate lower than 1.5x their own hourly rate. A 2003 amendment under the FY2004 NDAA guarantees the employee at least their own hourly rate for overtime, correcting an earlier problem where higher-grade employees could earn less per overtime hour than their regular hourly rate. The cap does not apply to wage employees or to FLSA overtime pay.
Under 5 U.S.C. 5547(a) and 5 CFR 550.105, the total of basic pay plus premium pay (including Title 5 overtime, the dollar value of compensatory time, night pay, Sunday premium, and holiday premium) in any biweekly pay period cannot exceed the greater of: the biweekly rate for GS-15 step 10 at the employee's locality, or the biweekly rate for Executive Schedule Level V. The cap applies to FLSA-exempt employees but does not apply to FLSA overtime pay earned by nonexempt employees. For employees performing emergency or mission-critical work, the agency head or OPM may authorize an annual cap instead, under 5 U.S.C. 5547(b).
Three distinct categories with different rules. Regular compensatory time under 5 U.S.C. 5543 is time off granted in lieu of monetary overtime pay, earned hour-for-hour at the overtime rate. Regular comp time must generally be used within 26 pay periods or forfeited. Credit hours under 5 U.S.C. 6121-6126 are earned under alternative work schedules by choosing to work additional hours within the basic 80-hour biweekly requirement; they are not overtime and carry different rules. Religious compensatory time off under 5 U.S.C. 5550a is earned by working additional hours specifically for the purpose of making up time taken off for religious observance; unlike regular comp time, it does not expire.
Yes. The One Big Beautiful Bill Act (OBBBA), P.L. 119-21, created a new individual income tax deduction for qualified overtime compensation. Under IRS Notice 2025-69 and guidance in IR-2026-10, qualified overtime compensation is the premium portion (the half in 'one and one-half times') of overtime pay required under FLSA section 7. For tax years 2026 and later, employers are required to report qualified overtime compensation separately on Forms W-2, 1099-NEC, and 1099-MISC. Federal FLSA-overtime-eligible employees should review the OPM FLSA overtime fact sheet and their agency payroll for specific calculation guidance. The deduction applies to the FLSA-required premium only; any amount paid beyond the FLSA requirement does not qualify.
