Federal Income tax is the largest tax for the government, it raises more money then anything else.
You do not have a set percentage amount that each taxpayer would pay annually in taxes. The tax bracket percentage amounts change for each taxpayers amount of taxable income that they end up having to use to determine the correct amount of their federal income tax liability after the federal income tax return is completed correctly down to the line on the 1040 federal income tax return that says taxable income. Then you would know the amount of your federal income liability for the year and would be able to determine your percent that is being collected from you from your income for the tax year.
