Federal income tax filing separately, 2024
This works out one number from the Tax Brackets figures published for 2024. 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.
Not the one you need? The same year also has federal income tax for a single filer, federal income tax for a married couple filing jointly.

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, married filing separately, $11,600 and 12% rate, 12% and 22% rate, married filing separately, $47,150 and 22% rate, 22% and 24% rate, married filing separately, $100,525 and 24% rate, 24% and 32% rate, married filing separately, $191,950 and 32% rate, 32% and 35% rate, married filing separately, $243,725 and 35% rate, 35% and 37% rate, married filing separately, $365,600 and Top rate, 37%, published above.
