How it's calculated

How federal income tax is calculated

US federal income tax is progressive — only the dollars inside each bracket are taxed at that bracket's rate. FICA is flat (mostly) and applies to gross wages, not taxable income.

Taxable = Wages − pre-tax 401k/HSA − std/itemized deduction
Federal tax = progressive 2026 brackets on taxable income
FICA = 6.2% SS (cap $184,500) + 1.45% Medicare
State tax = your state's effective rate on taxable income

2026 federal brackets at a glance

Brackets are inflation-adjusted each year. For 2026 the standard deduction is $16,100 (single) / $32,200 (MFJ) / $24,150 (HoH).

  • • Single: 10% to $12,400 → 12% → 22% → 24% → 32% → 35% → 37% above $640,600.
  • • MFJ: 10% to $24,800 → 12% → 22% → 24% → 32% → 35% → 37% above $768,700.
  • • Social Security wage base (2026): $184,500. Earnings above are SS-exempt but still owe 1.45% Medicare (+0.9% Additional Medicare > $200k single).

Pre-tax accounts that lower your bill

Every dollar into a traditional 401(k), HSA, or pre-tax health premium reduces taxable income at your marginal rate. For a 24%-bracket earner, $10,000 into a 401(k) saves $2,400 federal — and often another $400–900 in state tax.

  • • 401(k) / 403(b) employee deferral 2026: $24,500 ($32,500 with 50+ catch-up).
  • • HSA 2026: $4,400 self-only / $8,750 family ($1,000 catch-up at 55+).
  • • Traditional IRA: $7,500 / $8,600, deductibility phases out by income + workplace plan coverage.

FAQ

Why is my paycheck withholding higher than this estimate?

Withholding tables (W-4) are conservative on purpose so you don't owe at filing. Your true liability is closer to what we estimate here. Many people get refunds because they over-withhold.

Does this include the Additional Medicare tax?

Wages above $200,000 (single) / $250,000 (MFJ) implicitly trigger the 0.9% Additional Medicare. We don't break it out on a separate line at this view.

Where do refundable credits like the CTC fit?

We don't model individual credits (CTC, EITC, dependent care). Those reduce liability further. Confirm with your filing software or accountant.

Important: this is not tax advice

Calculations use simplified, current published brackets for United States (2025). US estimates layer the selected state's 2025 income tax rate on top of federal — local city taxes (e.g. NYC, Philadelphia) and progressive within-state brackets are not modelled.They do not account for credits, alternative minimum tax, the Net Investment Income Tax, foreign income, R&D credits, or your personal circumstances. Always confirm with a licensed CPA, chartered accountant, or registered tax agent before filing.
