How to Claim No Tax on Overtime

The four steps

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. 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. 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. 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 generally may claim only the qualified overtime compensation your employer actually reported in box 12 code TT. 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.

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.
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?

If the reported figure is understated, you generally need a corrected Form W-2 (Form W-2c) from your employer before claiming a larger deduction. You cannot substitute your own calculation for the reported amount. Start with your payroll department and explain which overtime hours you believe were left out.

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.
