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.
