What is the top income tax rate in United States in 2026?

37%, applied to taxable income in the highest bracket. Lower slices of income are taxed at lower rates — the top rate never applies to your whole income.

What is the difference between marginal and effective tax rate?

The marginal rate is the tax on your next unit of income (your current bracket). The effective rate is total tax divided by total income — always lower, because earlier slices were taxed at lower rates. Budget with the effective rate; evaluate a raise or side income with the marginal rate.

United States Income Tax Calculator (2026)

Computes United States personal income tax for 2026 using the official progressive brackets, and explains the number the way it actually works: your marginal rate versus your effective rate, how far you are from the next bracket, and exactly what this model excludes.

Basis: 2026 rates · IRS Rev. Proc. 2025-32 (tax year 2026), single filer

The numbers

Take-home (after income tax): 67,330; 5,611 / month
Income tax: 7,670
Effective rate: 10.2%
Marginal rate: 22%
Taxable income: 58,900

The operator’s read

Worth knowing

Your marginal rate is 22% but your effective rate is only 10.2% — only the income inside the top slice is taxed at 22%. A raise is never "eaten by the bracket": earning more always increases take-home.

Worth knowing

You are 46,800 of taxable income below the next bracket (24%). Crossing it only taxes the amount above 105,700 at the higher rate.

Caution

This models income tax only — it excludes state income tax, FICA (Social Security + Medicare), and credits; single filer with the standard deduction. Treat the take-home figure as an upper bound, not a paycheck prediction.

Methodology

Cumulative progressive calculation: each slice of taxable income is taxed at its bracket's rate — 10% up to 12,400, 12% up to 50,400, 22% up to 105,700, … up to 37% at the top. Taxable income = annual income − deductions.

Basis: IRS Rev. Proc. 2025-32 (tax year 2026), single filer. Bracket tables are updated when the jurisdiction publishes new rates; the tax year is stated in the tool name so you never mistake stale rates for current ones.

Scope: personal income tax only. Excluded: state income tax, FICA (Social Security + Medicare), and credits; single filer with the standard deduction. Real filings involve credits, reliefs, and personal circumstances this calculator deliberately does not guess at.
