Federal employees keep hearing that overtime is now tax-free. For most GS workers, it isn't. The OBBBA overtime deduction only applies to overtime that the Fair Labor Standards Act itself requires, and most white-collar GS employees are FLSA-exempt. One letter on your SF-50 settles it.
The 60-Second Self-Check: Do You Qualify?
Work through this before you plan a single dollar around the deduction.
Step 1. Pull your SF-50 from eOPF and read Block 35 (FLSA Category).
- E (Exempt): Stop. Your overtime is Title 5 overtime, not FLSA overtime. It does not qualify. If you also receive AUO or LEAP, those don't qualify either.
- N (Nonexempt): Keep going.
Step 2. Did you actually receive overtime pay in 2025 or 2026?
- No: there's nothing to deduct.
- Yes: keep going.
Step 3. Was that overtime FLSA overtime?
- Wage Grade (WG/WL/WS): almost certainly yes.
- Lower-grade GS clerical or technician work: likely yes.
- Federal firefighter above 212 hours in a 28-day period: yes, section 7(k) counts.
- Paid as an AUO percentage or LEAP: probably no. See a CPA.
Step 4. Count only the premium. The deductible amount is the half in time-and-a-half: your regular rate × 0.5 × overtime hours. Not the full overtime check.
Step 5. Apply the caps. Up to $12,500 per person ($25,000 married filing jointly). The deduction starts shrinking at $150,000 MAGI single / $300,000 joint and disappears entirely at $275,000 / $550,000.
Why "No Tax on Overtime" Skips Most GS Employees
The IRS definition is narrow: qualified overtime compensation is pay "required under section 7 of the Fair Labor Standards Act" that exceeds your regular rate. That single phrase decides everything for federal workers, because the government runs two separate overtime systems.
FLSA-nonexempt employees get overtime because federal labor law demands it. That's section 7 overtime, and its premium qualifies.
FLSA-exempt employees still get overtime pay, but under a different law entirely: Title 5 of the U.S. Code (5 U.S.C. 5542). Congress requires it, OPM administers it, and the FLSA has nothing to do with it. So it fails the IRS test by definition, even when the math happens to look like time-and-a-half.
Most GS analysts, specialists, program managers, engineers, attorneys, and IT professionals sit in the exempt bucket under 5 CFR Part 551. Grade alone doesn't decide exemption, duties do, but in practice the white-collar GS workforce above roughly GS-9 is mostly exempt.
There's a second insult buried in Title 5: for employees above GS-10, the overtime rate is capped. You get the greater of 1.5 times the GS-10 step 1 hourly rate for your locality (roughly $32 to $37 an hour in 2026, depending on where you work) or your own straight-time hourly rate. A GS-13 working nights and weekends is often earning overtime at barely more than the regular hourly rate, and now that capped overtime doesn't qualify for the tax deduction either.
The Four Kinds of Federal Overtime, and Which One Counts
| Pay type | Legal authority | Who gets it | OBBBA deductible? |
|---|---|---|---|
| FLSA overtime | FLSA section 7 (29 U.S.C. 207) | Nonexempt feds (Block 35 = N) | Yes, the premium portion |
| Title 5 overtime | 5 U.S.C. 5542 | Exempt feds (Block 35 = E) | No |
| FLSA 7(k) overtime | FLSA section 7(k) | Nonexempt firefighters and some LEOs, over 212 hrs/28 days | Yes, the premium portion |
| AUO / LEAP | 5 U.S.C. 5545(c)(2) / 5545a | Law enforcement, criminal investigators | Almost certainly no |
The AUO and LEAP rows deserve one caveat. The IRS has not addressed either program by name as of August 2026. Both are Title 5 premium pay, not FLSA overtime, so the statutory definition excludes them. But a small set of law enforcement positions receive AUO and also generate separate FLSA 7(k) overtime. In that narrow case, the 7(k) component might qualify while the AUO percentage does not. If that's you, this is a conversation with a CPA, not a DIY deduction. Our LEAP and AUO premium pay guide explains how these programs work.
Two Employees, Same Hours, Very Different Deductions
WG-10 electrician, FLSA-nonexempt. Regular rate $22.45 an hour, 10 hours of FLSA overtime a week. The premium is $22.45 × 0.5 × 10 = $112.25 a week. Over 50 working weeks that's about $5,600 of deductible premium, comfortably under the cap. At a 22% marginal rate, that's roughly $1,235 of real tax savings.
GS-13 program analyst, FLSA-exempt. Same 10 extra hours a week. Overtime paid under Title 5, capped by the GS-10 step 1 formula. Deduction: $0.
Same building, same hours, completely different tax outcomes. The dividing line is which law requires the overtime, not how hard anyone worked.
What Shows Up on Your W-2, and When
Tax year 2025 (filing in early 2026): employers weren't required to break out qualified overtime on the W-2. Some reported it voluntarily in Box 14. If yours didn't, you can reconstruct the premium portion from your Leave and Earnings Statements: regular rate × 0.5 × overtime hours, pay period by pay period. Keep the records.
Tax year 2026 and later: employers, including DFAS, must report qualified overtime separately in Box 12 under Code TT. For 2026 through 2028, only separately reported amounts qualify. If you're nonexempt and your Box 12 shows nothing, chase it with payroll before you file.
The deduction is temporary. It runs through tax year 2028 and disappears in 2029 unless Congress extends it.
The Fine Print That Bites
It's a deduction, not an exemption. A dollar of qualifying premium saves you your marginal rate, not the whole dollar. At 22%, the maximum $12,500 deduction is worth at most $2,750.
The premium-only rule surprises people. $5,000 of total overtime pay is not a $5,000 deduction. The premium buried inside it is roughly $1,667.
States mostly haven't followed. Federal employees in Maryland, Virginia, California, New York, and most other states get no state-level version of this deduction.
MAGI creep is real for feds. The phase-out starts at $150,000 single. A senior nonexempt employee in a high-cost locality, or a dual-fed household filing jointly near $300,000, can watch the deduction shrink or vanish.

Frequently Asked Questions
How do I know if I'm FLSA-exempt or nonexempt?
Check Block 35 on your SF-50, labeled FLSA Category. An E means exempt: your overtime is Title 5 overtime and does not qualify. An N means nonexempt: the premium portion of your FLSA overtime may qualify. The IRS Q&A on this deduction names SF-50 Block 35 specifically as the check for federal employees. Your SF-50 lives in your eOPF.
I'm a GS-12 analyst and worked 300 hours of overtime. Can I deduct it?
Almost certainly not. GS-12 analysts are typically FLSA-exempt, and exempt-employee overtime is paid under Title 5 (5 U.S.C. 5542), not required by FLSA section 7. The IRS definition only covers FLSA-required overtime, so Title 5 overtime fails the test regardless of how many hours you worked.
Does LEAP or AUO qualify?
Almost certainly not. Both are Title 5 premium pay authorities rather than FLSA section 7 overtime, and the IRS hasn't addressed either by name. Write them off for planning purposes. If you receive AUO and separately generate FLSA 7(k) overtime, that 7(k) premium might qualify. That's a CPA question.
Do federal firefighters qualify?
Usually yes. Firefighters typically fall under FLSA section 7(k), which triggers overtime above 212 hours in a 28-day work period. Section 7(k) is part of section 7, so that premium qualifies. Confirm your Block 35 shows an N.
Can I take this alongside the standard deduction?
Yes. It's an above-the-line adjustment on Schedule 1, so it stacks on top of the standard deduction. No itemizing required.
My 2025 W-2 shows no separate overtime amount. Am I stuck?
No. For 2025, separate reporting wasn't required, and the IRS allows you to reconstruct qualifying overtime from your LES records. From tax year 2026 on, your employer must report it in Box 12 Code TT, and only reported amounts count.
