Federal income tax for a single filer, 2026
This works out one number from the Tax Brackets figures published for 2026. Every amount it uses is below, with the document it was read from. What you enter is your own: this site has no way to check it, and the answer it produces is not a published figure.

How it is worked out
Each published rate applied only to the part of the amount you enter that falls inside its own band: the lowest rate from nothing up to the published starting amount of the next band, and each rate after that from its own published starting amount up to the next. The total is rounded to the nearest cent. No deduction, exemption or credit is taken off first, so what you enter has to be taxable income.
It uses 10% rate, 10% and 12% rate, single taxpayers, $12,400 and 12% rate, 12% and 22% rate, single taxpayers, $50,400 and 22% rate, 22% and 24% rate, single taxpayers, $105,700 and 24% rate, 24% and 32% rate, single taxpayers, $201,775 and 32% rate, 32% and 35% rate, single taxpayers, $256,225 and 35% rate, 35% and 37% rate, single taxpayers, $640,600 and Top rate, 37%, published above.
Figures in this colour are computed from the amounts above. They are not published figures and no document states them.
