What Percent of Taxes Is Deducted From My Paycheck?

Review your paystub for the taxes deducted each pay.

Almost everyone who works for a paycheck has taxes deducted each payday. There is no single percentage of taxes taken out of your paycheck. That is because there are several taxes, each calculated differently. Plus, federal and many state income tax rates vary depending on how much you earn, your filing status and the number of withholding allowances you claim.

Social Security and Medicare

Social Security tax and Medicare tax are two federal taxes deducted from your paycheck. The Social Security tax is 6.2 percent of your total pay until you reach an annual income threshold. The income threshold for 2017 was $127,200, but it is adjusted yearly. The percentage rate for the Medicare tax is 1.45 percent, although Congress can change it. Medicare tax is levied on all of your earnings, with no upper income threshold or limit.

Taxable Income

The federal income tax you pay depends partly on how much of your paycheck is considered taxable income. Taxable income is the amount left over after withholding allowances and other tax-exempt amounts are subtracted from your total pay. For example, in 2017 one withholding allowance was $4,050 annually, or $77.88 per week. If you claimed two allowances and you’re paid weekly, you would subtract $155.77 from your total weekly pay to find your taxable income for figuring federal income tax. You should also deduct any other tax-exempt items such as contributions to an employer-provided retirement plan.

Federal Income Tax

The percentage of federal income tax deducted from your paycheck rises as your taxable income increases. As of 2017, the first $44 per week was not taxed. Federal income tax was 10 percent of your weekly taxable income from $44 to $224. From $224 to $774 per week, the percentage was 15 percent. The percentage tax rises in each successive tax bracket until it reaches a maximum. In 2017, the maximum tax percentage was 39.6 percent for all taxable income in excess of $8,090 per week.

State and Local

Most states and some local governments also levy income taxes. Each state or local government has its own formula for figuring its income tax. To find out how these taxes on your paycheck are calculated, contact your state and/or local government department of revenue or taxation (see Resources).

Overall Percentage

If you’d like to calculate the overall percentage of tax deducted from your paycheck, first add up the dollar amounts of each tax withheld. Divide the total of your tax deductions by your total, or gross, pay. Multiply the result by 100 to convert it to a percentage.
