Have you ever noticed the 'FIT' on your pay stub and wondered what it is for? FIT stands for Federal Income Tax and is one of “the taxes on pay stub”. They calculate this tax based on your earning level and filing status. So invest time in acquainting yourself with a FIT, and you'll be on your way to financial success!


You will see the FIT tax when using your last pay stub to file taxes. The FIT tax, also known as the Federal Income Tax, is one of the essential taxes you will see on your pay stub. Furthermore, they typically withhold this tax from your paycheck and use it to fund the federal government. The amount of FIT tax you pay depends on your income level, filing status, and the number of allowances you claim on your W-4 form. 

What is 'FIT' On A Pay Stub

The  Federal Income Tax, or "FIT tax,” as it is known on the list of pay stub abbreviations, is a government-issued mandatory system. Moreover, this system dictates that the government should take a certain amount of money from any and every dollar you receive. In turn, the authorities will use this money to fund the government and make it run. Thus, they earmark this deduction on your pay stub. 

Federal Income Tax (FIT) Withholding

Knowing how to calculate payroll taxes, including Federal Income Tax (FIT) withholding, is an integral part of how people pay taxes in the United States. You'll see the FIT tax withheld every time you receive a pay stub. And they compute this by taking stock of your filing status, allowances, and other deductions.

How the FIT tax is Calculated

The calculation of the FIT tax begins with calculating the total net income for the business during the fiscal year. And this includes all revenue from operations minus any expenses related to doing business. It also considers any additional income generated from investments or other sources and any deductions for taxes paid in other countries, such as the United States. Once they calculate the net income for the fiscal year, they apply the FIT tax to this figure.

Example Calculation

To calculate the FIT tax, you'll need to take each employee's annual wages, subtract the applicable deductions, and multiply that amount by the current tax rate for that employee. For example, let's say Employee A has an annual salary of $50,000 and is eligible for a standard deduction of $6,300. After subtracting the deduction, the amount of taxable income is $43,700. Multiply that by the current tax rate of 22%, and the FIT tax you’ll pay is $9,614.

What Percentage of FIT is Taken Out of Paycheck?

Well, the answer is: it depends.  The authorities calculate this based on your income and other factors that vary depending on your filing status. Consequently, when you get your paycheck, you will see a deduction for FIT, usually around 10-15% of your gross pay. So that percentage can go up or down depending on your income, deductions, and other factors.
