How are US federal taxes calculated in 2026?
US federal income tax is calculated using a progressive bracket system. For 2026, taxpayers subtract the standard deduction ($14,600 for single filers, $29,200 for married filing jointly) from their gross income to determine their taxable income. This taxable income is then tiered across incremental tax brackets ranging from 10% to 37%. Use the calculators below to project your exact federal liability, self-employment taxes, and state withholdings.
