If you are employed in the United States, your earnings are reported as W-2 income. Federal income tax is automatically withheld from these wages, but many taxpayers are still unsure how the process works. This article explains how federal income tax applies to W-2 income in a clear and simple way.
What Is W-2 Income?
W-2 income refers to wages earned as an employee. Employers report this income to both the employee and the IRS using Form W-2, which shows:
- Total wages earned during the year
- Federal income tax withheld
- Social Security and Medicare taxes
- Employer details
Employers must issue Form W-2 by January 31 following the end of the tax year.
How Federal Income Tax Is Withheld From W-2 Income
Federal income tax on W-2 income is withheld by the employer from each paycheck. The amount withheld depends on:
- Your gross wages
- Filing status selected on Form W-4
- Any additional withholding requested
The IRS uses withholding tables to determine how much federal tax should be deducted from each pay period.
Understanding Federal Income Tax Brackets
The U.S. federal income tax system is progressive, meaning different portions of income are taxed at different rates. Lower portions of income are taxed at lower rates, while higher portions are taxed at higher rates.
This does not mean your entire salary is taxed at the highest rate you fall into. Only the portion above each threshold is taxed at that higher rate.
Deductions That Affect W-2 Income
Deductions reduce the amount of income subject to federal tax. Common deductions for W-2 employees include:
Standard Deduction
Most taxpayers claim the standard deduction, which automatically lowers taxable income.
Pre-Tax Payroll Deductions
Some deductions reduce taxable income before taxes are calculated, such as:
- Employer-sponsored retirement contributions
- Health insurance premiums
- Health Savings Account (HSA) contributions
Tax Credits Available to W-2 Employees
Tax credits reduce the actual tax owed. Depending on income and eligibility, W-2 earners may qualify for:
- Child Tax Credit
- Earned Income Tax Credit
- Education-related tax credits
These credits can significantly reduce overall federal tax liability.
Why You May Owe Tax or Receive a Refund
At tax filing time, the IRS compares total federal tax withheld with the actual tax owed.
You may receive a refund if excess tax was withheld or if you qualify for refundable credits.
You may owe additional tax if withholding was insufficient, if you worked multiple jobs, or if your W-4 details were not updated.
