1. What is Tax Deduction in Salary?

Tax deduction from salary refers to the amount withheld from an employee's gross salary for tax purposes, which may include additional allowances that affect the final tax calculation.

2. How Does the Calculator Work?

The calculator uses the tax deduction formula:

Where:

• \( \text{Salary} \) — Gross salary amount
• \( \text{Tax Rate} \) — Applicable tax rate as decimal (e.g., 0.20 for 20%)
• \( \text{Allowances} \) — Additional tax allowances or adjustments

Explanation: The formula calculates the basic tax amount (salary × rate) then adds any additional allowances that affect the total tax deduction.

3. Importance of Tax Calculation

Details: Accurate tax deduction calculation ensures proper withholding, prevents underpayment penalties or overpayment, and helps in financial planning.

4. Using the Calculator

Tips: Enter salary amount, tax rate as decimal (e.g., 0.15 for 15%), and any additional allowances. All values must be non-negative.
