No Tax on Overtime Deduction 2026: How to Claim Up to $12,500

What the No Tax on Overtime Deduction Is (in 2026)

The One Big Beautiful Bill Act (Public Law 119-21), signed July 4, 2025, created a new federal deduction for “qualified overtime compensation.” It lets eligible workers subtract a slice of their overtime pay from taxable income on their 2025 through 2028 returns.

Most articles bury the part that actually matters. Only the FLSA half premium is deductible. That’s the extra 0.5× you earn on top of your regular rate when time-and-a-half kicks in. The base hour itself still gets taxed normally.

If you make $25/hour and earn $37.50 for an overtime hour, the deductible piece is $12.50 (the half), not $37.50 (the whole). A common myth says the entire overtime check is tax-free. It isn’t.

The deduction is above-the-line, which means you can claim it whether you itemize or take the standard deduction. You still owe Social Security, Medicare, and state and local income tax on the overtime premium. This break is federal income tax only.

How Much You Can Deduct: Caps and the MAGI Phase-Out

The headline cap is $12,500 for single filers (or head of household) and $25,000 for married filing jointly. Married filing separately is excluded entirely, so couples who want the deduction must file a joint return.

The cap is the ceiling, not the floor. You can only deduct up to the actual FLSA premium you earned in the year. If you earned $3,200 in premium pay, your deduction is $3,200, not $12,500.

A Modified Adjusted Gross Income (MAGI) phase-out also applies. The deduction starts shrinking when MAGI exceeds $150,000 single or $300,000 joint. For every $1,000 of MAGI above the threshold, your maximum deduction drops by $100.

That puts the hard cutoffs at $275,000 single and $550,000 joint. Above those numbers you get nothing, no matter how much overtime you worked.

A quick worked phase-out. A single filer with $175,000 MAGI is $25,000 over the threshold. That trims the max deduction by $2,500 (25 × $100), so the ceiling drops from $12,500 to $10,000. If they only earned $4,000 in FLSA premium, they still get the full $4,000.

Who Qualifies (and Who Doesn’t)

You qualify if you are an FLSA non-exempt employee, the kind of worker legally entitled to overtime under federal law. You also need a valid Social Security Number. Joint filers must file jointly to claim it.

Several categories of “overtime-ish” pay don’t count. This is where workers in daily-overtime states get tripped up:

• State-mandated overtime. California’s daily overtime after 8 hours, Alaska’s daily 8-hour rule, Colorado’s daily 12-hour rule, and Nevada’s daily 8-hour rule for lower-paid workers all push you above straight time. None of those state-only hours count toward the federal deduction unless you also crossed 40 hours in the workweek.
• Union or contract overtime above FLSA. If your CBA requires time-and-a-half after 35 hours, the gap between 35 and 40 is contract OT, not FLSA OT, and is not deductible.
• Shift differentials and bonuses. Night-shift premiums, weekend differentials, holiday pay at 2×, and lump-sum bonuses paid at a higher rate are not FLSA overtime.
• Salaried exempt employees. If you are exempt from FLSA overtime, there is nothing to deduct.

The rule of thumb: if Section 7 of the FLSA (hours over 40 in a single workweek) doesn’t require your employer to pay you overtime on those hours, they aren’t qualified overtime.

What Changed in 2026: W-2 Box 12 Code TT

For tax year 2025, employers were not required to separately report qualified overtime compensation. Workers filing in early 2026 often opened their W-2 and saw nothing about overtime in Box 12 or Box 14. The IRS published Schedule 1-A as the form for the deduction, but the input number had to be self-calculated from pay stubs.

Tax year 2026 changes that. On January 9, 2026, the IRS finalized the new W-2 Box 12 Code TT, which employers must use to report total qualified overtime compensation. The same number appears on 1099-MISC Box 14 and 1099-NEC Box 1d for independent contractors who somehow earned FLSA-qualifying overtime through a payer.

That sounds like a fix, but it shifts the problem more than it removes it. Payroll systems still have to correctly distinguish FLSA OT from state OT, shift differentials, and bonuses. If your employer’s payroll software lumps California daily overtime into the Code TT total, your W-2 will overstate qualified overtime. If they miss a workweek where you crossed 40 hours, your W-2 will understate it.

Either way, the IRS expects the number on your return to match reality, and the burden of proof falls on you. That’s why a parallel record kept during the year matters more in 2026 than it did in 2025.

How to Claim It on Your 2025 or 2026 Return

The deduction lives on Schedule 1-A (Additional Deductions), Part III. The flow looks like this:

1. Enter qualified overtime compensation on line 14a (from W-2 Box 12 Code TT, or your reconstructed figure).
2. Run the phase-out worksheet if your MAGI exceeds $150,000 single or $300,000 joint.
3. Apply the cap ($12,500 single, $25,000 joint).
4. Transfer the final allowed deduction to Form 1040 line 13b.

A worked example, end to end:

• Regular rate: $25.00/hour
• FLSA overtime rate: $37.50/hour
• FLSA premium (the half): $12.50/hour
• Overtime hours in the year: 200
• Qualified overtime compensation: 200 × $12.50 = $2,500

This filer is single, MAGI $68,000, so no phase-out. The $2,500 goes on Schedule 1-A line 14a, flows through to Form 1040 line 13b, and reduces taxable income by $2,500. At a 22% marginal rate, that’s about $550 in federal income tax savings. Social Security, Medicare, and state tax on those overtime hours are unchanged.

Two pitfalls to avoid:

• Don’t enter total overtime pay ($7,500 in the example above). That triple-counts the deduction and will trigger a notice.
• Don’t forget that the phase-out reduces the cap, not the amount you earned. A high-income earner with $5,000 of premium and a phased-out cap of $3,000 deducts $3,000, not $5,000.

If Box 12 Code TT is blank or looks wrong, reconstruct the number from pay stubs. Pull each week where you exceeded 40 hours, multiply the overtime hours by your half premium for that week (regular rate × 0.5), and sum across the year. If you tracked hours independently, this takes a few minutes. If not, it can turn into a weekend project.

How to Track Qualified Overtime During the Year

This is the operational gap most tax articles skip. The deduction is only as accurate as the input number, and the input number is only as accurate as your records.

Pay stubs are a partial solution. Most show gross overtime pay (the full $37.50 per hour in the earlier example), not the FLSA half premium ($12.50). To get to the deductible figure you have to back out the regular rate, which requires you to know the workweek hours and the regular rate of pay used by payroll.

Payroll portals are sometimes better but inconsistent. Some show a year-to-date “OT premium” line; many do not. None of them flag a quarter where you are on pace to exceed the $12,500 cap, which is a question that matters for high-overtime workers in healthcare, manufacturing, and trades.

A workflow that works:

1. Log every shift with clock-in, clock-out, and breaks.
2. Tag each shift with the job so multi-job filers can apply the FLSA 40-hour rule per employer (each employer’s hours are tracked separately for federal OT).
3. Calculate the weekly FLSA premium as (hours over 40) × (regular rate × 0.5).
4. Reconcile each paycheck against your tracker. If your tracker says $312.50 in premium for the period and your stub disagrees, ask payroll.
5. Check year-to-date premium quarterly. If you’re headed past $12,500, you know the cap will bite and can plan withholding.

That’s the workflow ClockWage44 was built around: per-job shift logging with a weekly overtime mode that calculates the FLSA half premium to the cent on-device, no cloud upload required. The same engine that resolves your take-home pay also gives you a number you can drop straight into Schedule 1-A line 14a in January.

If you just want to run scenarios before committing to a tracker, the overtime calculator walks through the regular pay, overtime pay, and premium math for a single week. For the full picture across jobs and pay periods, see the hours-to-pay conversion guide for the underlying math.

A Note for Employers and Payroll Folks

If you run payroll, the 2026 reporting change adds a column. You need a payroll system that can:

1. Identify FLSA overtime hours by workweek per employee (not by pay period).
2. Separate FLSA OT from state daily OT, contract OT, shift differentials, and holiday premium.
3. Compute the half premium (overtime rate minus regular rate, times overtime hours) for each workweek.
4. Sum the annual figure into W-2 Box 12 Code TT (and the equivalent boxes on 1099-MISC and 1099-NEC).

Most modern payroll providers shipped Code TT support in early 2026, but small employers running spreadsheets or older systems are at higher risk of misreporting. A common error is including California’s daily-over-8 hours in the federal total. Another is failing to use the FLSA regular rate of pay (which includes non-discretionary bonuses) when computing the half premium.

The IRS estimates roughly 17 million workers will benefit from the deduction, with average tax cuts above $1,400 (Tax Policy Center) and a 10-year cost of $89 billion (Joint Committee on Taxation). That’s a lot of W-2s where the Box 12 Code TT number needs to be right.

Frequently Asked Questions

Is overtime really tax-free in 2026?

No. Only the FLSA half premium of time-and-a-half is deductible from federal income tax. Your base hourly rate, Social Security, Medicare, and state taxes still apply to overtime hours.

How much can I deduct under the no tax on overtime rule?

Up to $12,500 if filing single or head of household, or $25,000 on a joint return, capped at the actual FLSA premium you earned.

Does state overtime (like California’s daily over-8-hours rule) count?

No. Only overtime required by Section 7 of the FLSA (over 40 hours in a workweek) qualifies. State-only OT, union-contract OT above FLSA, shift differentials, and bonuses are excluded.

What is W-2 Box 12 Code TT?

Starting with 2026 W-2s (filed in early 2027), employers must enter your total qualified overtime compensation in Box 12 with code TT. For 2025 W-2s it was optional, so many workers had to calculate it themselves from pay stubs.

How do I claim the deduction on my tax return?

File Schedule 1-A (Additional Deductions), Part III. Enter qualified overtime on line 14a, follow the phase-out worksheet, and transfer the final number to Form 1040 line 13b.

What if my W-2 doesn’t show Box 12 Code TT or the number looks wrong?

Reconstruct it from pay stubs or your payroll portal. Multiply your overtime hours by the premium (the difference between your overtime rate and your regular rate), not the full overtime pay. An hours tracker with FLSA overtime calculation can produce this figure to the cent.

Does the deduction apply if I itemize?

Yes. It is above-the-line, so it works whether you itemize or take the standard deduction.

How long is the no tax on overtime deduction in effect?

Tax years 2025 through 2028, unless Congress extends it.
