No tax on overtime
The deduction is for qualified overtime compensation above the regular rate. It is claimed on the tax return. It does not stop Social Security or Medicare withholding.
What this estimate uses
The premium is half the hourly rate times overtime hours times 52. The cap and the phase-out are then applied. Tips have their own cap of $25,000, which is not doubled for a joint return. The phase-out reduces the overtime deduction first.
Questions
What is the cap?
$12,500 for single, head of household, and married filing separately. $25,000 for married filing jointly.
When does it phase out?
The deduction shrinks by $100 for each whole $1,000 of income over $150,000, or over $300,000 for married filing jointly.
Does a higher overtime multiplier increase the deduction?
Not in this estimate. The deductible piece stays at half the regular rate times the overtime hours.
Can I put this on Form W-4?
You can raise Step 4(b) if you want less federal income tax withheld. That does not change FICA, and this page does not fill out the form for you.
