Step 1: Determine Gross Salary

The first step in calculating your income tax on salary is determining your gross salary. Gross salary is the total amount of money you earn before any deductions are made, including:

  • Basic salary
  • Overtimes
  • bonuses and allowances
  • travel allowances


Step 2: Deduct Statutory Deductions

The next step is to subtract the statutory deductions from your gross salary. Statutory deductions are mandatory contributions that are deducted from your salary and include the following:

  • SSS (Social Security System) contributions
  • PhilHealth contributions
  • Pag-IBIG contributions

These deductions are not only used to provide social security benefits to workers but also serve to reduce your taxable income.


Step 3: Determine Taxable Salary

Once you have subtracted the statutory deductions from your gross salary, the next step is determining your taxable salary. Taxable salary is the amount of money you must pay income tax.


Step 4: Determine the Tax Bracket

Once you have determined your taxable salary, the next step is to determine your tax bracket. There are multiple tax brackets in the Philippines, each with a different tax rate. The tax rate that applies to you depends on the amount of your taxable salary.


Step 5: Calculate Tax Liability

Once you have determined your taxable salary and tax bracket, the final step is calculating your tax liability. The calculation is simple and involves multiplying your taxable salary by the tax rate that applies to your tax bracket.

It is important to note that the tax calculation in the Philippines is progressive, meaning the tax rate increases as your taxable salary increases. This is designed to ensure that those who earn more pay a higher percentage of their income in taxes.


Step 6: Pay Your Taxes

The final step in calculating your income tax on salary is to pay your taxes. In the Philippines, taxes are paid to the Bureau of Internal Revenue (BIR) every quarter. Taxpayers can pay their taxes online through the BIR website or by visiting a BIR office in person.
