James Ryan Jonas

Year after year, April 15 is a date millions of Filipinos dread. It is because this date is the annual deadline to file income tax returns.

If you’re able to make your own Income Tax Return (ITR) because you fully understand taxation laws, then good for you. But for the majority of us who still rely on accountants or our companies to prepare our ITRs, here’s a simple and concise explanation of the income tax law in the Philippines.


(UPDATE): The income tax rates below have been replaced by the new tax rates under the approved TRAIN Tax Reform of 2018.


Who are required to file Income Tax Returns (ITR)?

According to the Bureau of Internal Revenue (BIR), the following people are required to submit Income Tax Returns:

  • Filipino citizens residing in the Philippines receiving income from sources within or outside the Philippines

  • Domestic corporations receiving income from sources within and outside the Philippines
  • Foreign corporations receiving income from sources within the Philippines
  • Taxable partnerships
  • Estates and trusts engaged in trade or business

As you can see, almost everyone who makes money is required to file and pay income tax.
