FIT tax: What it is and how it affects wages and withholding

A significant part of understanding payroll for small businesses is Federal Income Tax withholding, (FIT). If you’re a small business owner, it’s essential to have a basic understanding of what it is, how to withhold it, and the purpose it serves. Read on for more insight…

What is FIT tax?

Federal income tax is withheld from each W-2 employees’ paychecks throughout a tax year. FIT tax pays for federal expenses like defense, education, transportation, energy and the environment, and interest on the federal debt.

There is also state income tax, or SIT, that goes towards state expenses, and is another line item on your employees’ paychecks.

How much is FIT tax?

FIT tax is calculated based on an employee’s Form W-4. Employers withhold FIT using either a percentage method, bracket method, or alternative method. The percentage method is based on the graduated federal tax rates (0%, 10%, 12%, 22%, 24%, 32%, 35%, and 37%) for individuals. The employee is responsible for this amount, and the FIT tax is drawn from each of their paychecks.

FIT tax is calculated using the following employee-related information:

  • ​Taxable earnings                                   
  • Pay frequency (such as weekly, biweekly, semimonthly, or monthly)                                                
  • Filing status
  • Number and type of dependents
  • Additional income, credits, deductions and other withholding requested on Form W-4

FIT taxable wages

The amount an employee pays for FIT tax depends on their FIT taxable wages. FIT taxable wages are different than FICA taxable wages.

FIT taxable wages for the purposes of FIT withholding and supplementary withholding include:

  • Bonuses
  • Salaries
  • Tips
  • Prizes and awards given to employees
  • Other taxable compensation and benefits

Some employee benefits are typically not included in wages subject to FIT withholding, such as employer provided health insurance coverage.

FIT withholding

You should calculate an employee’s federal income tax withholding with their Form W-4. The amount of FIT withholding will vary from employee to employee.

For example, a single employee making $500 per weekly paycheck may have $27 in federal income tax withheld per paycheck in 2021 if the employer uses the wage bracket method for standard withholding.
