1. What is Gross Income Tax Return Calculation?

The Gross Income Tax Return calculation determines the tax amount based on gross income minus allowable deductions, multiplied by the applicable tax rate. This is commonly used in the Philippines tax system to calculate income tax liabilities.

2. How Does the Calculator Work?

The calculator uses the tax calculation formula:

Where:

• \( Gross \) — Total gross income in PHP
• \( Allowances \) — Allowable deductions in PHP
• \( Rate \) — Applicable tax rate as a decimal

Explanation: The formula calculates taxable income by subtracting allowances from gross income, then applies the tax rate to determine the final tax amount.
