Many filers assume the deduction removes all overtime from taxable income. It doesn't. Only the premium portion that the Fair Labor Standards Act (FLSA) requires can qualify, and the deduction is capped and phased out at higher incomes.
This guide covers the eligibility test, the 2026 W-2 reporting, the form flow, the calculation and the records to keep. The 2026 Form 1040 and Schedule 1-A line numbers below come from IRS draft forms, so confirm them against the final versions before filing.
Key Takeaways
- Overtime stays taxable wages; only the FLSA-required premium may be deducted.
- The 2026 cap is $12,500 ($25,000 joint), phasing out above $150,000 ($300,000 joint) of MAGI.
- Claim it on Schedule 1-A, which feeds Form 1040 line 13a in the 2026 draft, not Schedule 1.
- Your employer should report qualified overtime in W-2 box 12, code TT.
What Counts as Qualified Overtime Compensation?
Qualified overtime is overtime required under section 7 of the FLSA and paid above your FLSA regular rate. A payment labelled "overtime" isn't enough. The IRC section 225 rules apply for calendar years 2025 to 2028, which includes 2026.
The premium-only rule
For ordinary time-and-a-half, only the "half" qualifies, not the straight-time pay for those hours. Take 10 overtime hours at a $20 regular rate. You receive $300, but only the $100 premium is potentially deductible.
Double time works the same way. The IRS example has 10 hours at double time producing $400, yet only the $100 FLSA-required half-time premium qualifies, not the full $200 extra actually paid.
What may not qualify
- Overtime required only by state law, an employment contract, a collective bargaining agreement or employer policy
- Pay for employees exempt from the FLSA, such as bona fide executive, administrative, professional, outside sales and certain computer employees
- Holiday or weekend pay where no FLSA overtime was owed (the day alone doesn't create overtime)
Job titles don't decide exemption. Duties and salary requirements do, so check the Department of Labor's Fact Sheets 17A and 23 rather than assuming every hourly worker qualifies.
2026 limits and conditions
| Rule | Most filers | Married filing jointly |
|---|---|---|
| Maximum deduction | $12,500 | $25,000 per return, not per spouse |
| MAGI phaseout starts above | $150,000 | $300,000 |
| Reduction | $100 per $1,000 over | Same |
These amounts are fixed by statute, not indexed for inflation. Other conditions:
- Married taxpayers must file jointly; married filing separately can't claim it.
- Each recipient needs an employment-valid Social Security number issued by the return due date, including extensions.
- MAGI is AGI plus amounts excluded under sections 911, 931 or 933.
The cap applies first, then the income reduction. The deduction can't fall below zero.
Where to Report Qualified Overtime on the 2026 Form 1040
Don't enter the deductible amount on the wage line. Report full wages on Form 1040 as usual, and claim the overtime deduction on Schedule 1-A (not Schedule 1).
The form flow (2026 drafts)
- Form 1040 line 1a: report W-2 box 1 wages, which already include all overtime pay.
- Schedule 1-A, Part III (lines 16 to 27): list each W-2 with employer name, EIN and the code TT amount, then apply the cap and phaseout. Line 27 is your overtime deduction.
- Schedule 1-A, Part VI, line 44: total your additional deductions.
- Form 1040 line 13a: carry the line 44 total here.
The IRS draft Schedule 1-A was posted in September 2026. The 2025 final form used different numbers (deduction on line 21, total on line 38 flowing to Form 1040 line 13b), so don't reuse last year's lines.
What your W-2 should show
For 2026, employers report qualified overtime compensation separately in box 12, code TT. That figure is the qualified premium reported by the employer, not your final deduction. Your cap and phaseout still apply.
Effect on your tax
The deduction isn't an above-the-line adjustment, so it doesn't reduce AGI. It lowers taxable income after AGI is calculated, and you don't need to itemise. It also doesn't reduce Social Security and Medicare taxes, which still apply to overtime wages.
Filing checklist
- Confirm W-2 box 1 wages and box 12 code TT
- Identify which overtime was FLSA-required
- Complete Schedule 1-A, Part III
- Carry line 44 to Form 1040 line 13a
- Check MAGI against the phaseout threshold
- Keep payroll records
How to Calculate and Claim the 2026 Overtime Deduction
For most employees, the qualified premium is hours over 40 in the workweek × one-half × your FLSA regular rate. Other FLSA section 7 arrangements can differ, so this isn't universal.
Step by step
- Add up the code TT amounts from each W-2.
- Check them against your pay stubs: overtime hours, rates and the regular rate.
- Remove anything not FLSA-required, such as contractual or state-only overtime.
- Enter the amounts on Schedule 1-A lines 16 to 17, then combine them on line 20.
- Apply the cap (line 21): the smaller of qualified overtime or $12,500/$25,000.
- Apply the phaseout (lines 22 to 26): subtract the threshold from MAGI, divide by $1,000, round down to a whole number, then multiply by $100.
- Subtract that reduction on line 27. If it's zero or less, enter zero.
Worked example
Assumptions: single filer, FLSA-covered and non-exempt, $20 regular rate, 50-hour week, 10 overtime hours at time-and-a-half.
- Regular pay for 40 hours: $800
- Overtime pay: 10 × $30 = $300
- Qualified premium: 10 × $10 = $100
Annualised, say the premium totals $4,000 and MAGI is $160,000. That is $10,000 over the threshold:
- Phaseout units: $10,000 ÷ $1,000 = 10
- Reduction: 10 × $100 = $1,000
- Deduction after phaseout: $3,000
If code TT is missing or wrong
For 2025 only, the IRS allowed alternative calculation methods using pay records. That relief doesn't carry into 2026. Under the IRS 2026 FAQs, omitted amounts need an employer-issued Form W-2c, and Form 4852 can't be used to establish this deduction. If the W-2 overstates qualified overtime, claim only the actual qualified amount.
Records, Special Situations, and Common Mistakes
Documents to keep
- Form W-2 and any corrected W-2c
- Pay stubs showing overtime hours and rates
- Employer statements and your employment classification details
- Your calculation worksheet
- Correspondence about payroll corrections
Keep these documents at least as long as the limitations period on the return.
Special situations
- Multiple employers: List each on Schedule 1-A (draft lines 16a to 16e); the cap applies once per return.
- Holiday or double-time pay: Count only the FLSA-required premium.
- Bonuses: Fold nondiscretionary bonuses into the regular rate; the bonus itself is not deductible.
- State or contract overtime: Assess each payment separately.
Common mistakes
- Deducting total overtime pay instead of the premium
- Treating every "OT" label as FLSA-qualified
- Entering the deduction on Schedule 1 or an old line number
- Estimating the amount when payroll records and the W-2 conflict

Frequently Asked Questions
Where do I report overtime on my Form 1040?
Overtime wages go in your W-2 total on line 1a. The qualified overtime deduction is calculated on Schedule 1-A and carried to Form 1040 line 13a in the 2026 draft. Verify against final forms.
Does overtime count as taxable income?
Yes. Overtime remains taxable wages, included in W-2 box 1, and is still subject to Social Security and Medicare tax. Only a qualifying premium may be deducted separately.
How do I calculate the tax on my overtime pay?
Payroll withholding is an estimate. Your actual tax comes from your total taxable income, less the allowable overtime deduction, under your filing status's rates.
Can I deduct overtime on my tax return?
Only qualified FLSA-required overtime premium can be deducted, up to $12,500 ($25,000 joint), reduced above the MAGI thresholds. Married couples must file jointly and need valid SSNs.
What is OT premium on a W-2?
It's the additional half-rate portion of overtime pay, reported in box 12 code TT for 2026. It's usually much smaller than your total overtime wages.
What is a Form 1040 U.S. Individual Income Tax Return?
Form 1040 is the main federal individual income tax return. Schedules such as Schedule 1-A support it, calculating deductions that carry into the return.
