What this calculator is doing
The 2025 tax law lets you deduct qualified overtime compensationfor tax years 2025 through 2028. Qualified overtime is not your overtime paycheck. It is only the premium the Fair Labor Standards Act requires on top of your regular rate — the extra half in “time-and-a-half.”
So if you earn $24 an hour and work 8 overtime hours, that week pays $288 in overtime, and $96 of it is qualified. Over 48 weeks that is $4,608 of deduction, not $13,824.
The cap and the phase-out
The deduction is capped at $12,500, or $25,000 if you are married filing jointly. Above $150,000 of modified adjusted gross income ($300,000 joint) it shrinks by $100 for every $1,000 you are over, and it can reach zero.
Why your paycheck stays the same
Withholding tables were not rewritten for this deduction. Your employer takes out the same tax it always did, and the deduction is applied on your return. If you want the money sooner rather than as a refund, the only lever is your Form W-4 — and adjusting it wrongly means owing money later, so that is a conversation for a tax professional.
What your employer has to report
Starting with tax year 2026, qualified overtime has to be reported separately on your W-2. Only overtime reported that way is deductible, which means an employer that does not track it correctly can cost you the deduction. If your pay stub does not separate the premium, ask payroll before January.
