How your paycheck is calculated
Federal income tax
Your employer withholds federal tax from each paycheck based on your W-4 form. The amount depends on your filing status, income, and allowances.
FICA taxes
Social Security (6.2% up to $176,100) and Medicare (1.45% + 0.9% Additional Medicare above $200,000) are withheld automatically from every paycheck.
State income tax
41 states and DC levy their own income tax. Rates vary from 1% (North Dakota) to 13.3% (California). 9 states have no income tax at all.
Pre-tax deductions
401(k) contributions, HSA, and health insurance premiums reduce your taxable income before tax is calculated, saving you money on both income tax and FICA.
How withholding works behind every paycheck
Your employer is required to estimate the federal income tax you will owe for the year and withhold that estimate in equal slices across your pay periods. The mechanism the IRS publishes is in Publication 15-T (Federal Income Tax Withholding Methods): payroll software annualises your period gross, subtracts the per-pay-period equivalent of the standard deduction, applies the brackets, then divides back into per-period withholding. Your W-4 form controls three knobs: filing status (which bracket schedule), multiple jobs / spousal income adjustment (step 2), and any additional withholding you specifically ask for (step 4c).
FICA payroll tax runs on a separate track. Social Security tax is a flat 6.2% of gross wages up to that year's wage base ($176,100 in 2025, $184,500 in 2026). Once you cross the base, no more Social Security withholding for the rest of the year — Medicare keeps going at 1.45% with no cap, plus an additional 0.9% on wages above $200,000 ($250,000 MFJ). Your employer matches every dollar of regular FICA, but does not match the 0.9% additional Medicare surtax. Self-employed earners pay both halves (15.3% combined) and reconcile via Schedule SE.
State income tax withholding follows each state's own bracket schedule. Nine states have no income tax at all (Alaska, Florida, Nevada, New Hampshire, South Dakota, Tennessee, Texas, Washington, Wyoming). The other 41 plus DC have rates ranging from a flat 2% (e.g. Indiana, Pennsylvania) up to 13.3% (California's top bracket on income over $1M). Some cities and counties also levy local income tax — New York City adds 3.0–3.9%, Philadelphia adds 3.75% wage tax for residents, and most Ohio municipalities add 1–2.5%.
Payroll thresholds for 2025 and 2026
The thresholds below are the ones every payroll system reads off the IRS and SSA publications each year. Numbers come from this site's central config — same source the calculator widget above uses — and update whenever new IRS Rev. Procs. or SSA fact sheets are released.
| Limit | 2025 | 2026 | Source |
|---|---|---|---|
| Social Security wage base | $176,100 | $184,500 | SSA Oct 2025 COLA |
| Additional Medicare threshold (single) | $200,000 | $200,000 | Statutory, unindexed |
| Additional Medicare threshold (MFJ) | $250,000 | $250,000 | Statutory, unindexed |
| 401(k) elective deferral (base) | $23,500 | $24,500 | IRS Notice 2025-67 |
| 401(k) catch-up (age 50+) | $7,500 | $8,000 | IRS Notice 2025-67 |
| HSA limit (self-only) | $4,300 | $4,400 | IRS Rev. Proc. 2025-19 |
| HSA limit (family) | $8,550 | $8,750 | IRS Rev. Proc. 2025-19 |
The Social Security wage base reset happens on 1 January every year. If you crossed the base mid-year in 2025, your January 2026 paycheck will see Social Security tax resume — a common surprise that catches high-earners who budget off November/December net pay.
Pre-tax deductions and how they reshape take-home pay
Three classes of pre-tax deduction reduce your paycheck differently — the tax savings depend on which payroll-tax bases each one bypasses.
Triple-shielded (federal + state + FICA)
- HSA contributions ($4,300 self / $8,550 family, 2025) routed through payroll
- Section 125 cafeteria-plan health insurance premiums
- Dependent care FSA (up to $5,000 MFJ)
- Medical FSA
- Commuter / transit pre-tax benefits
These bypass federal income tax, state income tax, AND the 6.2% / 1.45% FICA base — the biggest combined saving per dollar deferred.
Federal + state only (NOT FICA)
- Traditional 401(k) elective deferrals
- Traditional 403(b) / 457(b) deferrals
- Pre-tax pension contributions
Save federal + state income tax, but you still pay 7.65% FICA on the deferred amount. A $1,000 deferral in the 22% bracket saves $220 federal but not the $76.50 FICA.
Post-tax (reduces net but not tax)
- Roth 401(k) contributions
- After-tax mega-backdoor contributions
- Employee Stock Purchase Plan (ESPP) payroll deductions
- Garnishments / wage levies
- Union dues, charitable payroll giving
These reduce take-home but generate no current-year payroll-tax savings. Roth contributions buy future tax-free withdrawals instead.

Common paycheck mistakes worth avoiding
- A W-4 left at "Single, 0" after marriage. The post-2020 W-4 has no allowances — filing status alone now controls the bracket schedule used. If your W-4 still says single after you got married, you are over-withholding by 5–15% of paycheck.
- Forgetting step 2 when both spouses work. The default W-4 assumes only one earner; two earners filing MFJ will under-withhold unless step 2 is filled in. The W-4 withholding calculator and W-4 withholding optimizer show the correction.
- Routing HSA outside payroll. A direct-to-HSA bank-transfer contribution gets the federal-tax deduction at filing but NOT the FICA saving. Payroll-routed HSA bypasses FICA — typically $200+ extra savings per $3,300 family contribution.
- Ignoring the SS wage-base reset. Mid-year hires who started above the wage base often miscalculate January take-home because Social Security tax resumes on day 1 of the new year.
- Forgetting state-of-work vs state-of-residence for remote work. Some states (NY, NJ, CT, NE, PA convenience rule) tax remote workers based on the employer location, not where you sit. The multi-state allocator walks through the split.
- Treating a bonus as taxed at a higher rate. Bonuses use 22% flat supplemental withholding (or 37% above $1M), but your actual marginal rate depends on annual taxable income. See the bonus tax calculator.
Frequently asked questions
What is FICA tax?
FICA stands for the Federal Insurance Contributions Act and funds Social Security and Medicare. In 2025, employees pay 6.2% for Social Security on wages up to $176,100 and 1.45% for Medicare on all wages, for a combined FICA rate of 7.65%. Your employer pays a matching 7.65% on your behalf.
How much Social Security tax is withheld from my paycheck?
Social Security tax is withheld at 6.2% of your gross wages up to the 2025 wage base of $176,100. Once your cumulative earnings for the year exceed that threshold, no additional Social Security tax is withheld for the rest of the year. Medicare tax of 1.45% has no wage cap, and an additional 0.9% Additional Medicare Tax applies to wages above $200,000.
How does a 401(k) contribution affect my take-home pay?
Traditional 401(k) contributions are deducted from your paycheck before federal income tax is calculated, which lowers your taxable income and reduces your tax withholding. However, 401(k) contributions are still subject to FICA taxes. Contributing $500 per paycheck typically reduces take-home pay by only $350–$400, depending on your tax bracket.
What is the difference between gross and net pay?
Gross pay is your total earnings before any deductions, including your full salary or hourly wages plus any overtime or bonuses. Net pay (take-home pay) is what you actually receive after subtracting federal income tax, FICA taxes, state taxes, and any pre-tax deductions like 401(k) contributions or health insurance premiums. The IRS publishes Publication 15-T with the official federal-withholding tables that determine how much your employer holds back each pay period.
How does my pay frequency (weekly, biweekly, semi-monthly, monthly) change anything?
It changes the per-period dollar number, but not the annual tax. Biweekly pay yields 26 cheques per year (52 ÷ 2). Semi-monthly is exactly 24 (twice a month). Monthly is 12. Weekly is 52. The withholding software annualises whichever per-period gross you have, computes the annual tax, then divides back down — so swapping from biweekly to semi-monthly only smooths the bumps; total annual federal tax is the same.
Why is my first paycheck of the year smaller than my last one?
Because Social Security tax restarts on 1 January. If you crossed the wage base in November or December, Social Security stopped withholding for the rest of that year — your December paycheck was inflated by the 6.2% that no longer applied. Once January 1 hits, the 6.2% Social Security withholding resumes from dollar one until you cross the new base.
What is the cliff at $200,000 / $250,000 of wages?
That's the start of the 0.9% Additional Medicare Tax. Your employer is required to withhold the extra 0.9% on YOUR wages above $200,000 regardless of filing status. But the actual liability is computed on a household basis: $200,000 single / $250,000 MFJ / $125,000 MFS. Couples filing MFJ where both earn just under $200,000 individually may face the surtax even though no single paycheck triggered employer withholding — reconcile on Form 8959.
How is overtime taxed?
For 2025 OBBBA introduced a federal-tax deduction (no tax on the overtime premium portion) up to certain caps. The Social Security and Medicare portion of overtime still apply normally. The no-tax-on-overtime calculator models the OBBBA benefit.
What is the difference between traditional and Roth 401(k) contributions on a paycheck?
Traditional 401(k) is pre-tax: it reduces federal taxable wages now (and state, for most states) but you still pay 7.65% FICA on it. Roth 401(k) is post-tax: it does NOT reduce taxable wages, so your federal withholding stays the same — Roth shrinks net pay by the full contribution amount. Both share the same elective deferral cap ($23,500 in 2025, $24,500 in 2026, plus catch-up amounts for age 50+).
Are employer 401(k) match contributions taxed on my paycheck?
No. Employer match goes directly into the 401(k); it does not appear in Box 1 wages or in your gross pay number. Traditional employer match is pre-tax (taxed on withdrawal). The SECURE 2.0 Act allows employers to offer Roth match starting 2024 — if you elect Roth match, the match amount is added to your Box 1 wages and taxed in the year contributed.
Why does the IRS withholding always seem off by a few dollars?
Federal withholding uses estimation tables that round and group income across brackets — designed to land close to your actual liability but not exact. Year-end reconciliation on Form 1040 corrects any difference: a refund if over-withheld, a balance due if under-withheld. Big differences point to a stale W-4 or missing step-2 multi-job adjustment.
Does state tax come out of every paycheck in every state?
In states with income tax, yes — employers withhold based on state W-4 forms and state-specific bracket schedules. Nine states (Alaska, Florida, Nevada, New Hampshire, South Dakota, Tennessee, Texas, Washington, Wyoming) have no state income tax. Some cities and counties (NYC, Philadelphia, Cleveland, most Ohio municipalities) layer on local income tax with separate withholding lines.
