How Paychecks Are Taxed in 2026: Federal, FICA & State Explained

Answer first: a 2026 paycheck loses money to three layers — federal income tax (10%–37% brackets after a $16,100 single standard deduction), FICA payroll tax (6.2% Social Security to $184,500 plus 1.45% Medicare), and state income tax (0% in eight states, up to 13.3% in California). On a $75,000 single salary in California that means $58,651.65 take-home; in Texas, $61,592.50.

The three layers on every pay stub

Every US paycheck passes through the same three deductions, in this order:

1. Pre-tax deductions (401(k), HSA/FSA) come off gross pay first and shrink everything below.
2. Federal income tax applies to the remainder minus the standard deduction, using marginal brackets.
3. FICA applies to nearly all wages, and state tax applies per your work state.

Layer 1: Federal income tax (2026 brackets)

For 2026 (IRS Rev. Proc. 2025-32) the seven rates are unchanged — 10%, 12%, 22%, 24%, 32%, 35%, 37% — but every threshold moved up about 4% for inflation. Single-filer bands start at $12,400, $50,400, $105,700, $201,775, $256,225, and $640,600.

Crucially, brackets are marginal: a single filer with $100,000 of taxable income does not pay 22% on all of it. They pay 10% on the first slice, 12% on the next, and 22% only above $50,400 — about $16,712 total, a 16.7% effective rate. Quoting your bracket overstates your bill.

Layer 2: FICA — the flattest tax you pay

Component	2026 rate	Applies to
Social Security	6.2%	Wages up to $184,500
Medicare	1.45%	All wages, no cap
Additional Medicare	0.9%	Wages over $200k single / $250k joint

Two subtleties matter. First, 401(k) contributions escape income tax but not FICA — most calculators model this wrong. Second, HSA/FSA money through payroll escapes both. The paycheck calculator handles the split the way payroll actually works.

Layer 3: State income tax — $0 to 13.3%

Eight states levy no wage income tax at all: Alaska, Florida, Nevada, New Hampshire, South Dakota, Tennessee, Texas, and Wyoming (Washington taxes capital gains only). Fifteen states use a single flat rate; the rest graduate up to California's 13.3%. Watch for what brackets hide: New York City tax, Maryland county taxes (~2.4% average), and California disability insurance all sit outside the state tables.

Worked example: $75,000 single in California vs Texas

	California	Texas
Gross (biweekly)	$2,884.62	$2,884.62
Federal income tax	$7,670	$7,670
FICA	$5,737.50	$5,737.50
State income tax	$2,940.85	$0
Take-home / paycheck	$2,255.83	$2,368.94

The state line alone is worth $3,000+ a year here — before considering that Texas funds itself with higher property and sales taxes. Compare total budgets, not just paychecks, with the Texas and California calculators side by side.

When to recheck your withholding

• After every raise or job change — withholding tables annualize each paycheck, so mid-year changes drift.
• After moving states — the state line can swing thousands overnight.
• After marriage or a new 401(k) rate — both rewrite your taxable income.
• Every fall — compare a late-year stub against the calculator and fix your W-4 before April.
