1. What is Withholding Tax?

Withholding tax is income tax withheld from employees' wages and paid directly to the government by the employer. The amount withheld is a credit against the income taxes the employee must pay during the year.

2. How Does the Calculator Work?

The calculator uses the withholding formula:

Where:

• \( \text{income} \) — Gross income amount
• \( \text{rate} \) — Applicable tax rate (as decimal)
• \( \text{allowances} \) — Tax allowances or deductions

Explanation: The formula calculates the estimated tax to be withheld based on income, tax rate, and any applicable allowances.

3. Importance of Withholding Tax Calculation

Details: Accurate withholding ensures employees don't owe large amounts at tax time while also avoiding over-withholding that reduces take-home pay unnecessarily.

4. Using the Calculator

Tips: Enter income in dollars, tax rate as a percentage (e.g., 20 for 20%), and allowances in dollars. All values must be non-negative.
