Federal income tax is the tax that the IRS (Internal Revenue Service of the United States) charges annually on individual earnings, as well the income of trusts, corporations, and other entities. Income can be from jobs, investment capital gains, and many other sources. The federal tax is separate from state income tax.

Federal income tax is the biggest source of US government revenue. The federal government uses it to fund programs ranging from infrastructure projects to disaster relief to education. It also pays government workers, sends relief to the poor, funds special projects like space exploration, and much more.

How Much Is Federal Income Tax?

Federal income tax is calculated yearly based on a percentage of your income. What percentage is used? This depends on the tax bracket you are currently in, which is based on your income level. Tax law changes each year, so these numbers can be different from one year to the next. For 2020 taxes, for example, these are the percentages of income you pay in tax and the income amounts that put you in that bracket:

10%

Single (and Married Filing Separately): $0–$9,875
Married Filing Jointly: $0–$19,750
Head of Household: $0–$14,100

12%

Single (and Married Filing Separately): $9,876–$40,125
Married Filing Jointly: $19,751–$80,250
Head of Household: $14,101–$53,700

22%

Single (and Married Filing Separately): $40,126–$85,525
Married Filing Jointly: $80,251–$171,050
Head of Household: $53,701–$85,500

24%

35%

One other nuance of the federal income tax system is that you owe a given percentage of tax only on the income within that bracket. For example, a single person who earned $30,000 during 2020 would owe 10% on the first $9,875 of her income and 12% on her income between $9,876 and $30,000.
