How to Use the DOF Tax Calculator

A DOF Tax Calculator is a digital tool that helps individuals and businesses estimate their tax obligations based on their annual income using the Department of Finance’s tax brackets.

This calculator is particularly useful for employees, freelancers, and business owners who want to quickly understand how much of their income goes to taxes and how much remains as take-home pay. Instead of manually computing your tax dues using tax tables, the calculator automates the process in seconds.

What the DOF Tax Calculator Does

The DOF Tax Calculator applies the official progressive tax brackets defined by the government (in this example, based on the Philippines’ TRAIN Law). It estimates:

Your total annual tax due
Your net take-home pay after taxes

By entering your annual income, you instantly get a clear breakdown of your financial obligations.

How to Use the Calculator

Open the calculator in your browser.
It runs on simple HTML, CSS, and JavaScript—no installation required.
Enter your annual income.
Input your gross yearly income in Philippine pesos (₱).
Click "Calculate Tax."
The calculator will display three key results:
- Your Annual Income
- Your Estimated Tax Due
- Your Take-Home Pay after tax

Example

If you earn ₱500,000 annually:

Tax = ₱30,000 + 25% of (500,000 – 400,000) = ₱55,000
Take-Home Pay = ₱445,000

The calculator shows these numbers instantly, saving you time.

Why Use a DOF Tax Calculator?
