No Tax on Overtime: Why Your W-2 Counts Only the Half

You picked up ten extra hours most weeks this year. Holiday rush, a coworker on leave, a manager who kept asking. You heard about no tax on overtime and assumed every overtime dollar would come back to you at tax time.

Then your W-2 arrives in late January. There is a new line in box 12, marked code TT, and the number is about a third of the overtime on your pay stubs. Nothing went wrong. That smaller number is the deduction, and this is the first year your employer's figure is the only one you are allowed to use.

This guide shows how the number is built, what it saves on a real wage, who gets nothing, and what both workers and small employers should check before the forms go out.

What Changes on This Year's W-2

Last year, employers got a pass. The IRS waived the separate reporting requirement for that first year, so many workers saw no overtime figure at all and estimated their own.

That relief is over. In its updated IRS fact sheet FS-2026-13, published in August, the agency says employers must report qualified overtime on Form W-2, box 12, code TT. The same document states the hard rule for workers: you can deduct only the qualified overtime that your employer put on a properly furnished W-2.

The IRS General Instructions for Forms W-2 and W-3 set the deadline at February 1 for both handing W-2s to employees and filing them with the Social Security Administration. A few workers will see the figure elsewhere. If someone counts as an employee under federal wage law but is paid as a contractor, the amount goes on Form 1099-NEC (box 1d) or 1099-MISC (box 14). The IRS calls that case rare.

One thing does not change. Overtime is still part of your wages. It still shows in box 1, and Social Security and Medicare taxes still come out of it. The break happens later, on Schedule 1-A of your Form 1040, and the deduction is scheduled to run through the 2028 tax year.

Only the Half Counts: How Qualified Overtime Is Measured

Here's where most people's math goes wrong. "Qualified overtime compensation" is not your overtime pay. It is only the extra part the federal Fair Labor Standards Act requires, the "half" in time-and-a-half.

The IRS gives employers a formula for each workweek:

• Hours worked over 40 in that workweek
• times one-half
• times your regular rate of pay

Three details decide whether that number is right.

The workweek, not the pay period

The IRS defines a workweek as a fixed 168-hour stretch. Each one stands alone, with no averaging across weeks. Work 45 hours one week and 35 the next, and you still earned five hours of premium in the first week.

The regular rate includes more than your base wage

Under federal law, the regular rate covers all pay for the work, including things like production bonuses and shift differentials, divided by hours actually worked. A bonus raises your regular rate, which raises the premium.

Extra generosity does not count

Many employers pay more than the law demands. The IRS is blunt about it: only the amount "minimally necessary" under federal law qualifies. Its own example uses a $20 hourly worker who logs 50 hours and gets double time. The employer pays $400 for the 10 overtime hours, but federal law required $300, so only $100 is qualified overtime.

The same logic shuts out overtime that exists only because of a state rule or a union contract. Daily overtime after eight hours, weekend premiums and overtime after 35 hours are generous, but they fall outside the formula unless the week also crosses 40 federal hours.

Worked Example: What No Tax on Overtime Saves on a $24 Wage

Take a warehouse lead earning $24 an hour who works 48 hours a week for 20 busy weeks. Her pay stubs show overtime at $36 an hour.

• Overtime pay on the stubs: 8 hours x $36 x 20 weeks = $5,760
• Qualified overtime (code TT): 8 hours x $12 x 20 weeks = $1,920
• Deduction: $1,920, well under the $12,500 cap

If her income sits in the 12% federal bracket, the deduction cuts her federal income tax by about $230. In the 22% bracket, it is about $422. Those are real savings. They are also far below the $5,760 she might have expected to shield.

Now suppose her employer's payroll system reports the full $5,760 in code TT by mistake. The IRS says she may claim only what was actually qualified, $1,920. Claiming the inflated figure invites a notice later, so compare code TT with your own count before you file. A quick check: for straight time-and-a-half, code TT should be roughly one-third of your total overtime pay.

If you also want to see how a raise or extra hours shift your bracket, our breakdown of what the new tax brackets let your raise keep walks through the same math from the other direction.

Who Gets Nothing From the Deduction

A large share of people who work long weeks will see no code TT at all. If federal law does not require your employer to pay you overtime, none of your overtime qualifies, even if you are paid for it.

• Exempt salaried staff: executive, administrative and professional employees, many computer roles and outside sales.
• Certain industries: some commissioned retail staff, motor carrier and railroad workers, seasonal amusement employees and some farm workers, according to the IRS list.
• Owners on payroll: an employee who holds at least a 20% equity stake and actively manages the business counts as an exempt executive, the IRS says.
• Married people filing separately: you must file jointly to claim it.
• Workers without a valid Social Security number for employment.

Higher earners lose some or all of it too. The deduction shrinks once modified adjusted gross income passes $150,000 for single filers or $300,000 for joint filers.

Small business owners already juggling pay floors should note the overlap. Some states tie the overtime-exempt salary to their minimum wage, as our guide to why minimum wage increases cost more than the hourly raise explains. Move a manager from exempt to hourly and that person starts generating code TT.

If Your W-2 Is Wrong, Only a W-2c Fixes It

This is the part that catches workers off guard. In past years, if a W-2 was missing information, you could often reconstruct it. For this deduction, you cannot.

The IRS fact sheet walks through the scenarios:

• Code TT too low: ask your employer for a corrected Form W-2c. If you get one, you claim the corrected amount.
• Employer refuses or cannot correct it: you are stuck with the lower figure, even if you can prove you earned more.
• Substitute W-2 (Form 4852): not accepted for this deduction.
• Code TT too high: you may claim only the overtime actually qualified.

So the window that matters is before you file. Pull your last pay stub of the year and add up the weeks you went over 40. Then multiply the overtime hours by half your regular rate and compare. If the gap is large, raise it with payroll in writing in early February. A small employer correcting a few forms is far easier than one that has moved on to spring.

What Small Employers Should Do Before February 1

For a business with a dozen hourly staff, the work is mostly a data problem. Payroll registers record overtime pay, not the federal premium, so the two rarely match.

1. Rebuild hours by workweek. Pull timekeeping data, not just pay-period totals, so overtime split across two paychecks is caught.
2. Recompute the regular rate. Fold in nondiscretionary bonuses and differentials, then take half of that rate for each overtime hour.
3. Strip non-federal overtime. Daily overtime, double time beyond the federal half and overtime paid to exempt staff stay out of code TT.
4. Use the pay date. The IRS ties timing to when wages are paid, so a late-December week paid in January belongs to next year's W-2.
5. Keep your worksheet. Employees will ask, and you will need it for any W-2c.

Errors carry a price. The IRS information return penalty page lists, for returns and statements due in 2027, $60 per form if corrected within 30 days, $130 if corrected by August 1, and $340 after that. For 15 employees with a wrong code TT fixed in the spring, that is $1,950 at the middle tier, before any time spent on corrections.

Withholding is the one thing you should not change on your own. The IRS says employers may not reduce withholding for the deduction unless the employee hands in a new Form W-4 that accounts for it. If you are tidying up other paperwork before the year closes, our list of year-end tax moves for small business owners covers the rest.

Frequently Asked Questions

Is overtime pay tax free now?

No. Overtime is still taxable wages and still has Social Security and Medicare taxes taken out. The no tax on overtime rule is a federal income tax deduction for the premium half of required overtime, claimed on Schedule 1-A, up to $12,500 per return or $25,000 on a joint return.

What does code TT mean on my W-2?

Code TT in box 12 is the total qualified overtime your employer paid you during the year. It is the federal premium only, so for time-and-a-half pay it is about one-third of your overtime earnings. It is your starting number on Schedule 1-A, and the caps and income limits are applied there.

Can I claim the overtime deduction if my employer did not report it?

Not for this tax year onward. The IRS says workers can deduct only qualified overtime reported in box 12, code TT. If the amount is missing or too low, you need a corrected Form W-2c from your employer. A substitute Form 4852 does not count.

Does double time or daily overtime qualify for the deduction?

Only partly. If you earn double time, only the half-rate premium required by federal law qualifies. Overtime owed only under a state daily rule or a union contract does not qualify unless the hours also push the week over 40.

Check the Number Before You File

No tax on overtime is a real break, but a narrower one than the name suggests. The deduction follows the federal premium, the federal workweek and, from now on, the exact figure your employer prints in box 12.

It's worth ten minutes in early February to run your own estimate against code TT. Workers should flag gaps while payroll can still fix them. Employers should rebuild overtime by workweek now, because a W-2c in February costs far less than a wave of them in April.
