If you worked overtime in 2026, your W-2 contains an important piece of information that can help you understand whether you may qualify for the federal qualified overtime deduction.
For 2026 and later tax years, employers are required to report qualified overtime compensation separately on Form W-2 using Box 12, Code TT. This makes your W-2 especially useful when preparing your tax return.
However, Code TT does not mean that your overtime pay is tax-free. It reports the amount of qualified overtime compensation that may be relevant when calculating the federal deduction.
You can use our No Tax on Overtime Calculator to estimate your potential federal tax savings, but your final deduction should be based on your actual tax documents and tax-return information.
What Is W-2 Box 12 Code TT?
For 2026, employers use Box 12, Code TT to report qualified overtime compensation.
The amount reported under Code TT represents the qualified overtime amount that may be used when determining the federal overtime deduction.
This is different from your total overtime paycheck.
For example, suppose your regular rate is $20 per hour and you receive time-and-a-half overtime pay.
Your overtime rate would be:
$20 × 1.5 = $30 per hour
The additional overtime premium is:
$30 – $20 = $10 per hour
The qualified overtime amount is generally based on this additional premium rather than the entire $30 overtime wage.
That distinction is important.
Where Do I Find the Overtime Amount on My W-2?
Look at your Form W-2 after receiving it from your employer.
You will generally see:
- Box 1 – Wages, tips, other compensation
- Box 3 – Social Security wages
- Box 5 – Medicare wages and tips
- Box 12 – Additional information and codes
For 2026, look in Box 12 for:
Code TT
The amount next to Code TT is the qualified overtime compensation reported by your employer.
Your Box 12 may contain other codes as well, so do not assume that every amount in Box 12 relates to overtime.
Is Code TT the Same as My Total Overtime Pay?
No.
This is one of the most important points to understand.
Your total overtime pay can include:
- Your normal hourly compensation for the overtime hours
- The additional overtime premium
For a common time-and-a-half arrangement, only the additional premium portion generally represents qualified overtime compensation for this federal deduction.
Simple Example
Suppose:
- Regular hourly rate = $20
- Overtime hours = 100
- Overtime rate = $30
Total overtime wages:
100 × $30 = $3,000
The additional premium:
100 × ($30 – $20) = $1,000
The qualified overtime amount could therefore be approximately $1,000 in this simplified example.
The exact amount reported by your employer on Code TT is what you should use when preparing your tax return.
Why Is My Code TT Amount Smaller Than My Overtime Pay?
This is normally expected.
The federal deduction is designed around qualified overtime compensation rather than the entire amount of overtime wages.
With time-and-a-half overtime, the extra half of the regular rate is the portion generally associated with the qualified overtime premium.
For example:
| Regular Rate | Overtime Rate | Total OT Pay for 100 Hours | Additional Premium |
|---|---|---|---|
| $15 | $22.50 | $2,250 | $750 |
| $20 | $30 | $3,000 | $1,000 |
| $25 | $37.50 | $3,750 | $1,250 |
| $30 | $45 | $4,500 | $1,500 |
These examples are simplified and assume the overtime qualifies under the applicable FLSA rules.
What If I Worked Double-Time Overtime?
Not every dollar above your normal wage automatically becomes qualified overtime compensation.
If you receive a higher overtime rate, the calculation can become more complicated.
For example, an employer might pay 2 times your regular rate.
The total amount paid for the overtime hour is:
Regular rate × 2
But the qualified federal overtime amount is generally tied to the FLSA-required premium rather than simply treating the entire additional payment as deductible.
Your W-2 Code TT amount is therefore more useful than trying to estimate the qualified amount from your total overtime wages alone.
What Are the 2026 Overtime Deduction Limits?
For 2026, the maximum federal qualified overtime deduction is:
| Filing Status | Maximum Deduction |
|---|---|
| Single | $12,500 |
| Head of Household | $12,500 |
| Married Filing Jointly | $25,000 |
| Married Filing Separately | $12,500 |
The deduction is also subject to an income-based phaseout.
The phaseout begins when modified adjusted gross income exceeds:
- $150,000 for most individual filers
- $300,000 for married taxpayers filing jointly
This means your reported Code TT amount is not necessarily the same as the final amount you can deduct.
How Does MAGI Affect the Deduction?
The overtime deduction is subject to an income limitation.
As income increases above the applicable threshold, the maximum available deduction is reduced.
For example, for a taxpayer subject to the $150,000 threshold, the phaseout calculation applies to the amount by which MAGI exceeds $150,000.
The reduction is calculated in $100 increments based on the applicable IRS rules.
Because of this, two workers with the same qualified overtime amount may receive different deductions if their income levels are different.
Does Overtime Become Tax-Free?
No.
This is an important distinction.
Qualified overtime compensation is not simply removed from your paycheck or excluded from all taxes.
Your overtime wages can still be subject to:
- Federal income tax withholding
- Social Security tax
- Medicare tax
- Applicable state and local taxes
The federal qualified overtime deduction is a tax-return deduction. It does not mean your employer should stop withholding taxes from your overtime paycheck.
Why Was Federal Tax Still Withheld From My Overtime?
Because withholding and your final tax liability are different things.
Your employer generally calculates paycheck withholding under payroll rules.
The qualified overtime deduction is determined when you calculate your federal income tax.
Therefore, you may see federal income tax withheld from overtime during the year even if you later qualify for a federal overtime deduction when filing your return.
This is one reason an overtime paycheck can appear to be taxed heavily.
What If My Employer Does Not Show Code TT?
For 2026 and later, employers are required to report qualified overtime compensation using the applicable W-2 reporting requirements.
If your W-2 appears to be missing or incorrectly reporting qualified overtime compensation, contact your employer or payroll department.
If necessary, you may need a corrected Form W-2, commonly called a W-2c.
Do not simply enter an amount that you calculated yourself if your tax documents do not support it.
Can I Calculate the Deduction From Box 1?
Box 1 and Code TT serve different purposes.
Box 1 reports wages and other compensation included in federal income.
Code TT separately reports qualified overtime compensation for the applicable reporting year.
Do not subtract your Code TT amount from Box 1 yourself and assume the result is your taxable income.
The federal tax return uses its own calculation rules.
How to Use the W-2 With Our Calculator
Our No Tax on Overtime Calculator is designed to provide an estimate of potential federal tax savings.
For a basic estimate, you can enter information such as:
- Filing status
- Regular hourly rate
- Overtime hours
- Weeks worked
- Estimated MAGI before overtime
- Tax year
The calculator estimates qualified overtime compensation and applies the applicable federal limits and phaseout rules.
For the most accurate tax-return calculation, use your actual W-2 and the applicable IRS forms and instructions.
Example: Reading a W-2 for Overtime
Suppose you receive a W-2 showing:
- Regular wages included in Box 1
- Additional overtime wages during the year
- Box 12 Code TT showing $6,000
The $6,000 Code TT amount is not necessarily $6,000 of tax savings.
Instead, it is the reported qualified overtime compensation amount that may be used in determining your deduction.
If your income is below the applicable phaseout threshold and the amount is below the annual deduction limit, the full qualifying amount may potentially be deductible.
Your actual result can be different depending on your filing status, MAGI, other tax-return information, and IRS rules.
W-2 Code TT vs Total Overtime Pay
| Item | What It Represents |
|---|---|
| Regular wages | Your normal compensation |
| Total overtime pay | Full amount paid for overtime hours |
| Overtime premium | Additional amount above the regular rate |
| W-2 Code TT | Employer-reported qualified overtime compensation |
| Federal overtime deduction | Amount ultimately allowed under the tax rules |
Keeping these terms separate can prevent many common mistakes.
Common W-2 Overtime Mistakes
Mistake 1: Treating all overtime pay as deductible
The federal deduction does not generally apply to your entire overtime paycheck.
Mistake 2: Treating Code TT as tax savings
Code TT reports qualified overtime compensation. It does not tell you how much tax you will save.
Mistake 3: Ignoring the income phaseout
Higher MAGI can reduce the amount of deduction available.
Mistake 4: Assuming overtime is exempt from payroll taxes
The deduction does not generally eliminate Social Security or Medicare taxes.
Mistake 5: Using your own estimate when the W-2 is available
When you have an actual W-2, use the employer-reported information and applicable IRS instructions rather than relying only on an estimate.
