Part-Time Hourly Tax Calculator 2026: What You Take Home
Part-time workers face a different tax math than full-timers. Lower gross income often drops you into a lower federal bracket, but FICA still hits at 7.65% on every dollar. This tool computes accurate 2026 take-home pay for 15, 20, 25, and 30 hour weeks across all states.
How Part-Time Tax Math Differs from Full-Time
The federal tax system is progressive, your effective tax rate is much lower than your top bracket. A part-time worker earning $20,000/year pays roughly $500 in federal income tax after the $16,100 standard deduction, which is an effective rate around 2.5% on gross. Compare that to a full-timer at $50,000 paying about $4,300 (8.6% effective).
FICA is the leveler. The 6.2% Social Security + 1.45% Medicare apply to every dollar of wages regardless of total income. A part-timer keeps far more of each gross dollar as federal income tax, but loses the same 7.65% to FICA.
Add the OBBBA Section 70202 overtime deduction and the picture gets even more interesting for part-time workers who occasionally pick up extra shifts, the overtime premium tax-free up to $12,500 effectively makes those hours worth more than base pay.

Gross annual at 52 weeks. Subtract roughly 7.65% for FICA and 0-12% federal tax depending on level.
Multiple Part-Time Jobs: The Withholding Trap
If you work two part-time jobs each paying $18,000/year, your combined income is $36,000, but each employer withholds as if you only earn $18,000. Both employers think you're below the standard deduction threshold, so they withhold almost no federal tax. Come April, you owe $1,400-$2,000 plus possible underpayment penalty.
Fix this on your W-4 at the higher-paying job: check Step 2(c) (multi-job worksheet) and enter extra withholding on Step 4(c). About $40-60 per pay period extra withholding will close the gap.
Part-Time and Healthcare: ACA Coverage Math
If you're under 30 hours/week, your employer is not required to offer ACA-compliant health coverage. Marketplace plans with premium tax credits can be more affordable than employer coverage at the same income level. The 2026 advance premium tax credit (APTC) phases out at 400% of poverty level, about $60,240 single / $124,800 family of four.
Pre-tax health insurance premiums through your employer reduce both federal AND FICA. ACA marketplace premiums are post-tax (federal deduction only if itemizing). A part-time worker eligible for either should compare net cost after tax effects, not just sticker premium.
