1. What Is Payroll Income Tax?

Payroll income tax is the amount withheld from an employee's gross pay for federal and state income taxes. Employers are required to withhold these taxes based on IRS guidelines and employee W-4 information.

2. How Does The Calculator Work?

The calculator uses the payroll tax formula:

Where:

• \( Tax \) — Amount of tax withheld ($)
• \( Gross \) — Gross income amount ($)
• \( Withholding Rate \) — Tax withholding rate (%)

Explanation: The formula calculates the tax amount by multiplying gross income by the withholding rate percentage, then converts it to dollar amount.

3. Importance Of Tax Withholding

Details: Proper tax withholding ensures compliance with tax laws, avoids underpayment penalties, and helps employees manage their tax liability throughout the year rather than facing large tax bills at filing time.

4. Using The Calculator

Tips: Enter gross income in dollars and withholding rate as a percentage. The calculator will compute both the tax amount and net pay after tax withholding.
