Overtime deduction phaseout: worked examples above the income threshold
Apply the deduction cap, complete-$1,000 income steps, and zero floor with examples for single and joint filers.
A correctly calculated overtime premium can be larger than the deduction your return allows. The annual cap and the income phaseout are separate steps, and applying them in the wrong order can produce a misleading estimate.
The examples below isolate that arithmetic. They assume an eligible taxpayer, correctly supported qualified overtime, and the stated modified adjusted gross income. They are original planning examples, not a completed return or a forecast of your refund.
Start with qualified compensation and the correct income measure
For the federal overtime deduction, the annual cap is $12,500 for an eligible non-joint return and $25,000 for a joint return. The income reduction begins above $150,000 of MAGI, or $300,000 for joint filers. Married taxpayers generally must file jointly to claim this deduction.
MAGI is not your take-home pay, and it is not necessarily your base salary. Schedule 1-A starts with adjusted gross income and adds specified excluded amounts. In a household worksheet, include the complete income picture before assessing whether overtime puts you near a threshold. Do not subtract the planned overtime deduction first to make the income test easier.

Cap first, then apply the income reduction
The current calculation uses $100 of reduction for each complete $1,000 above the applicable threshold. The published 2025 Schedule 1-A explicitly rounds the number of thousands down. Subtract the reduction from the smaller of qualified compensation and the cap, with a minimum result of zero.
The linked 2025 form documents that arithmetic; it is not a filing form for 2026. Use the final form and instructions for the year you are filing. The examples express the calculation independently so a line-number change does not change the explanation.
The planning sequence
- Starting amount = smaller of qualified compensation and the filing-status cap.
- Excess income = greater of MAGI minus the threshold, or zero.
- Complete steps = excess income ÷ $1,000, rounded down.
- Reduction = complete steps × $100.
- Allowed amount = greater of starting amount minus reduction, or zero.

Original example: $8,000 qualified compensation and $173,450 MAGI
Assume an eligible single filer has $8,000 of qualified compensation. The cap does not reduce that starting amount because $8,000 is below $12,500. MAGI is $23,450 above the threshold, giving 23 complete thousand-dollar steps.
The resulting $5,700 deduction is an income reduction, not a $5,700 tax saving. If that entire deduction happened to offset income taxed at 24%, the simplified savings would be $1,368. That final multiplication is only an illustration; a full tax calculation may involve multiple brackets and other interactions.
Single-filer calculation
- Starting amount: min($8,000, $12,500) = $8,000.
- Excess MAGI: $173,450 − $150,000 = $23,450.
- Complete steps: floor($23,450 ÷ $1,000) = 23.
- Reduction: 23 × $100 = $2,300.
- Deduction: $8,000 − $2,300 = $5,700.
Original example: apply the joint cap before the phaseout
Assume an eligible joint return has $30,000 of combined qualified overtime and $312,900 MAGI. The cap reduces the starting amount to $25,000. The income reduction then subtracts $1,200, producing $23,800.
Subtracting $1,200 from $30,000 and only then applying the cap would incorrectly produce $25,000. The sequence matters when qualified compensation exceeds the cap. The joint limit is a return-level limit; do not apply a new full cap separately to every employer statement.
Joint-return calculation
- Starting amount: min($30,000, $25,000) = $25,000.
- Excess MAGI: $312,900 − $300,000 = $12,900.
- Complete steps: 12; reduction: 12 × $100 = $1,200.
- Deduction: $25,000 − $1,200 = $23,800.
A smaller deduction can disappear earlier
The often-quoted full phaseout endpoint assumes a taxpayer started with the maximum deduction. If a single filer has only $2,000 of qualified compensation, a $2,000 reduction is enough to eliminate it. At $170,000 MAGI, twenty complete steps produce exactly that result.
This is why a calculator should apply a dollar reduction to your actual capped amount rather than simply test whether income is below a maximum endpoint. At $169,999 MAGI in the same illustration, nineteen complete steps leave $100. At $170,000, twenty steps leave zero. These examples use stated whole-dollar MAGI and isolate the phaseout logic.
Check the assumptions before making a financial decision
Keep the source of each input beside the number: employer qualified-overtime reporting, chosen filing status, and the income estimate used for MAGI. When comparing additional overtime shifts, include the additional wages in the projected income as well as the additional premium; changing only one side produces an inconsistent scenario.
Finally, separate deduction, estimated income-tax savings, and paycheck withholding in your notes. The phaseout calculation addresses only the first. It does not calculate state tax, payroll tax, benefit eligibility, or the entire economic value of working an extra shift.
- Do not phase out gross overtime wages instead of qualified compensation.
- Do not round partial thousand-dollar steps up in this calculation.
- Do not apply the cap after subtracting the phaseout.
- Do not assume every taxpayer retains a deduction until the maximum-cap endpoint.
