What Is the FIT Deduction on My Paycheck?

by David Sarokin ; Updated September 11, 2015

A paycheck generally includes a bewildering collection of terms, acronyms and numbers that detail your gross earnings and numerous adjustments and deductions to arrive at your take-home pay. Adding to the confusion, employers are not required to use consistent terminology on earnings statements. Some employers use the acronym FIT to indicate deductions for federal income tax.

Earnings Statement

Employees generally receive a paycheck along with additional information -- an earnings statement -- explaining how the amount on the check was calculated. The information can be printed on a pay stub attached to the check or can be provided as a separate document. The earnings statement also includes information on accrued sick leave, annual leave and other benefits such as contributions to a retirement plan.

Gross Pay and Net Pay

Your earnings statement indicates your gross pay, which is the total amount of money earned for the pay period prior to any deductions. The statement also has an entry for net pay, which is the actual amount of money you have left, known as take-home pay, after reductions are made for taxes and other deductions.


FIT represents the deduction from your gross pay to pay federal withholding, also known as income taxes. FIT deductions are typically one of the largest deductions on an earnings statement.

Other Deductions

The federal government also requires deductions from gross earnings for Social Security and Medicare. There are generally deductions for state or local taxes as well. Deductions for other categories may also be listed, such as union dues or employee contributions to retirement plans.

Additional Information

Earnings statements typically contain information beyond an accounting of gross earnings, deductions and net pay for the pay period. The details vary from employer to employer, but earnings statements often include cumulative earnings and deductions for the year, the amount of annual leave accrued and used, summary of sick leave accrued and used, details of hours worked and the types of hours, such as straight time or overtime.
