BEHIND THE NUMBERSOvertime tax savings begin with a deduction, not a special tax rate on every overtime dollar. This calculator separates gross overtime pay, qualified compensation, and the estimated federal income tax reduction.

01
From qualified overtime pay to federal tax savings
First, determine the qualified FLSA premium. Apply the $12,500 non-joint or $25,000 joint limit. Then reduce that amount using the IRS income phaseout if MAGI exceeds $150,000 or $300,000, respectively.
The tax benefit is the difference between estimated federal income tax before and after the allowed deduction. Using taxable income for this comparison matters: MAGI determines the phaseout, while taxable income determines the ordinary income tax brackets.
THE FORMULAEstimated savings = federal income tax before the deduction − federal income tax after the deduction
02
How the 2026 overtime deduction phaseout works
Schedule 1-A first caps qualified compensation, then subtracts an income-based reduction. Its overtime worksheet rounds the number of income increments down to a whole number. Being slightly above the threshold does not necessarily cause an immediate reduction.
The deduction cannot go below zero. The income at which your deduction disappears depends on the qualified amount you started with; a smaller deduction runs out sooner than the maximum deduction. A reported W-2 amount does not bypass this calculation.
03
Overtime withholding and your final tax bill
An overtime paycheck can show substantial withholding even when you expect to claim the deduction. Overtime wages remain subject to federal income tax withholding. IRS guidance allows employees to account for an expected deduction through a valid updated Form W-4.
A refund is the result of your complete return, including tax already paid and applicable credits. The savings shown here are not a promised refund or a prediction of your next paycheck. Payroll taxes and state income taxes are outside this federal income tax estimate.
04
Check your overtime deduction inputs before filing
For 2026 onward, reconcile qualified overtime with box 12, code TT on your W-2. If the amount is missing or too low, request a corrected W-2 from your employer; an estimate based on hours cannot replace that reporting requirement.
Use your tax return's MAGI and deductions when making a filing decision. Wage-only estimates can differ when you have other income, adjustments, itemized deductions, or credits. The examples below isolate the deduction and assume each stated tax rate applies to the entire deductible amount.
