How to Claim No Tax on Overtime

Which box on your W-2, which form on your return, and what to do when the number is wrong.

The short answer

Find your qualified overtime compensation in W-2 box 12, code TT (required from tax year 2026; for 2025 many employers used box 14 instead). Enter it on Schedule 1-A, Additional Deductions, attached to your Form 1040 — no itemizing required. Apply the $12,500 cap ($25,000 joint) and the phase-out above $150,000 of modified AGI ($300,000 joint). You need a valid SSN, and if married you must file jointly. If the reported figure is too low, get a corrected W-2 (W-2c) — you cannot substitute your own math.

The four steps

  1. 1. Find your qualified overtime figure

    For tax year 2026 and later, it is reported in W-2 box 12 under code TT. For tax year 2025, separate reporting was not required — many payroll providers used box 14 with a label such as "FLSA OT Prem", and some reported nothing at all.

  2. 2. Complete Schedule 1-A

    Schedule 1-A (Additional Deductions) is the form the IRS created for this group of deductions. Attach it to your Form 1040, 1040-SR or 1040-NR. You do not have to itemize — this sits alongside the standard deduction rather than replacing it.

  3. 3. Apply the cap and the phase-out

    The deduction is limited to $12,500 ($25,000 joint) and is reduced by $100 for each $1,000 of modified AGI over $150,000 ($300,000 joint). The form walks the arithmetic; the figure your employer reports is the starting point, not the answer.

  4. 4. Check the filing conditions

    A valid Social Security number must be on the return, and married taxpayers must file jointly. Filing separately disqualifies the deduction entirely.

The reported number wins, not your calculator

This is the single most important thing on this page. From tax year 2026, you may claim only the qualified overtime compensation your employer actually reported in box 12 code TT. That is not IRS preference, it is the statute: 26 U.S.C. §225(a) allows a deduction for qualified overtime included on statements furnished to you. The tax-year 2025 relief that let you compute the figure yourself does not carry forward. A calculator — including ours — is a planning tool. It tells you whether extra shifts are worth taking and roughly what your refund might look like. It does not produce a figure you can enter on a return in place of the reported one.

The practical use for the estimate is as a check. If your own arithmetic says roughly $6,000 of qualified premium and box 12 says $1,200, that gap is worth a conversation with payroll before you file.

When the W-2 is understated

Ask your employer for a Form W-2c, the corrected wage statement. Common causes of a low figure: overtime paid under a contract or state daily rule that payroll did not treat as FLSA-required, a mid-year payroll system change, or a bonus that should have been folded into the regular rate before the overtime premium was calculated. That last one also means your overtime pay itself may have been short — the overtime calculator helps you check the gross figure independently.

Push on this, because the downside is real and it is not appealable. If your employer will not issue the W-2c, the deduction you lose is simply gone — you may claim only the reported amount. A substitute W-2 (Form 4852), the form normally used when an employer fails to furnish a W-2, does not rescue it either: 26 U.S.C. §225(a) allows the deduction only for qualified overtime on a statement furnished under the W-2 rules, and Form 4852 is not one. The mirror case is worth knowing too: if box 12 is overstated, you may only count the qualified overtime you were actually paid.

Getting it in your paycheck instead

The deduction does not change your withholding by itself, and your employer is not permitted to lower your overtime withholding on its own initiative. If you would rather have the money during the year than as a refund, furnish a new Form W-4: the 2026 version added step 4(b) for the deductions you expect, and the IRS Tax Withholding Estimator was updated to account for qualified overtime. Be conservative — overtime schedules change, and withholding too little means a bill in April.

Tax year 2025 was different

The first year of the deduction ran under transition relief. Employers were not required to report qualified overtime separately, so W-2s varied: box 14 with a descriptive label, a separate statement, or nothing at all. If you have an unclaimed 2025 deduction, payroll can usually still produce the figure. The dates and what changed between the two years are on when it starts.

Before you file

  • Confirm you are eligible at all — who qualifies.
  • Check the phase-out against your modified AGI — income limits.
  • Sanity-check the reported figure against your own arithmetic — worked examples.
  • Confirm you are reading current rules — IRS guidance tracks which fact sheet supersedes which.
  • If married, remember that filing separately forfeits the deduction entirely.
  • Remember your state may tax the overtime the federal government now lets you deduct. Check your state revenue department; the state pages cover the labor-law side.

Claiming it — FAQ

How do I claim the no tax on overtime deduction?
Take the qualified overtime compensation your employer reported — W-2 box 12, code TT for tax year 2026 and later — and enter it on Schedule 1-A (Additional Deductions), attached to your Form 1040. Apply the $12,500 cap ($25,000 joint) and the modified-AGI phase-out. You do not need to itemize, but you do need a valid SSN, and married filers must file jointly.
What is W-2 box 12 code TT?
It is the box where employers report qualified overtime compensation, required from tax year 2026 onward. The amount shown is the total qualified overtime your employer paid you during the year — the FLSA-required premium half only, not your full overtime earnings. Your employer reports the full qualified amount even if caps or phase-outs mean you cannot deduct all of it.
What if my employer reported the wrong amount?
It depends which way it is wrong. If the figure is UNDERSTATED, you must request a corrected Form W-2 (Form W-2c) from your employer — and if the employer is unwilling or unable to issue one, you may only deduct the amount that was reported, even though you genuinely earned more. A substitute W-2 (Form 4852) does not work here, because 26 U.S.C. §225(a) requires the amount to be on a W-2 furnished by the employer. If the figure is OVERSTATED, you may only count what you were actually paid, not the inflated figure. Start with payroll, in writing, and name the overtime hours you believe were left out.
Can I get the benefit in my paycheck instead of waiting for a refund?
Yes, by adjusting your withholding yourself. Your employer may not reduce withholding on overtime to account for this deduction on its own initiative — but you can furnish an updated Form W-4 that reflects the deduction you expect for the year. The 2026 Form W-4 added step 4(b) for exactly this, and the IRS Tax Withholding Estimator was updated to handle it. Estimate conservatively: if you over-adjust and your overtime dries up, you will owe at filing.
What if nothing was reported for 2025?
That was permitted — 2025 ran under transition relief with no mandatory separate reporting. Ask payroll what your qualified overtime compensation was for the year; many can produce the figure even though they were not required to print it on the W-2. If you were eligible and did not claim it on a return you already filed, ask a tax professional about amending.
Do I need special tax software?
Any software that supports Schedule 1-A handles it, and the major consumer products added it for the 2025 filing season. If you file on paper, the schedule attaches to your 1040 like any other. What matters is having the reported qualified overtime figure in front of you before you start.
