If you see FITW on your paycheck, it stands for Federal Income Tax Withholding.
FITW is the amount of federal income tax your employer withholds from your wages and sends to the Internal Revenue Service (IRS) on your behalf.
Unlike FICA taxes, FITW is based on your income, filing status, and the information you provided on your Form W-4.
What Does FITW Mean on a Paystub?
FITW simply means your employer is withholding federal income tax from your paycheck.
You may also see it labeled as:
• Federal Tax
• Fed Tax
• FIT
• FWT
• Federal Withholding
All of these refer to federal income tax being deducted from your wages.
How Is FITW Calculated?
Federal income tax withholding depends on several factors:
1. Your Gross Pay
The more you earn, the more federal tax you may owe.
2. Your W-4 Elections
Your Form W-4 tells your employer:
• Your filing status
• Whether you have dependents
• Whether you want extra tax withheld
• Whether you have multiple jobs
These selections directly affect how much FITW is deducted.
3. IRS Tax Brackets
Federal income tax is progressive. That means higher portions of income are taxed at higher rates.
Your employer uses IRS withholding tables to calculate how much to deduct each pay period.
Why Is FITW Different Each Paycheck?
FITW can change because:
• Your hours worked changed
• You received overtime or a bonus
• You updated your W-4
• You started a new job
• You moved into a different tax bracket
Bonuses, in particular, may have a higher withholding rate applied.
Does FITW Reduce My Take-Home Pay?
Yes.
FITW is deducted from your gross wages before you receive your net pay.
Example:
If you earn $1,500 in gross pay and $200 is withheld for FITW, your take-home pay will be reduced by that amount, along with other deductions such as FICA.
What Is the Difference Between FITW and FICA?
This is one of the most common paycheck questions.
FITW:
• Federal income tax
• Based on tax brackets
• Determined by your W-4
• Funds general government operations
FICA:
• Payroll tax
• Fixed percentage rates
• Funds Social Security and Medicare
• Required for most workers
They are separate deductions and calculated differently.
Can I Reduce My FITW?
You may be able to adjust your federal withholding by submitting a new Form W-4 to your employer.
However, reducing withholding too much could result in owing taxes when you file your annual return.
If too much FITW is withheld during the year, you may receive a tax refund.
Why Is My FITW So High?
Common reasons include:
• You selected “Single” filing status
• You did not claim dependents
• You have multiple jobs
• You received a large bonus
• You requested extra withholding
If you believe too much tax is being withheld, review your W-4 elections carefully.
Where Can I Verify My Federal Withholding?
You can:
• Review IRS Form W-4 instructions
• Use the IRS Tax Withholding Estimator
• Check your annual Form W-2
Your W-2 will show total federal income tax withheld for the year in Box 2.
