How it works
The US uses progressive brackets: each slice of taxable income is taxed at its own rate. We subtract the 2026 standard deduction and apply the 2026 federal brackets. State and local income taxes, credits, and itemized deductions are not included. This is an estimate, not tax advice.
Formula
Taxable = Income − pre-tax deductions − standard deduction Tax = Σ (income in each bracket × bracket rate)
Example
A single filer earning $85,000 in 2026 has $68,900 of taxable income and owes roughly $9,800 in federal tax.

Frequently asked questions
Does moving into a higher bracket reduce my take-home pay?
No. Only the income above each threshold is taxed at the higher rate.
What's the difference between effective and marginal rate?
Marginal rate applies to your last dollar earned. Effective rate is your total tax divided by total income.
