How to Compute Your Income Tax in the Philippines
Most people will agree that seeing your tax in your payslip does not create happy thoughts.
How can you be sure that the right amount has been deducted from your hard-earned salary?
To set it straight:
Withholding tax is the tax deducted by your employer from your salary every payday or every month depending on what you have agreed on. The withholding tax is simply the partial payment of your income tax.
Income tax is your tax annually which you have to file to avoid penalties.

How to Compute Withholding Tax?
If you want to understand more about how to compute your tax Philippines, follow these steps.
Step 1: Know the formula for finding your taxable income
Monthly Basic Pay + Overtime Pay + Holiday Pay + Night Differential – Tardiness- Absences – SSS/Philhealth/PagIbig deductions = Taxable income
Your taxable income is your total income minus the deductibles.
The deductibles are expenses which the BIR allows to be deducted from your salary so you will have a lower taxable income. These can be (but not limited to) SSS, GSIS, Philhealth, HDMF and Other Contributions.
Step 2: List down the amount you have earned and the amount deducted from your income.
Let’s say you are earning a basic pay of P15,000 without any other additional income:
- Monthly Basic Pay = P15,000
- Overtime Pay = none
- Holiday Pay = none
- Night Differential = none
- Tardiness = none
- Absences = none
- SSS = P545
- PhilHealth = P187.5
- Pag-IBIG deductions = P100
Total Deductions: P832.50
Taxable Income: P14,167.50
Step 3: Understand the BIR Tax table and compute the withholding tax based on it
BIR Income Tax table
The BIR tax table is the reference the company’s HR or accountant uses. You can easily find a copy online.

The BIR Income Tax Table tells you how much your tax will be. However, it is not simple. You still have to compute based on your civil status, dependents, and income frequency.
Define your salary frequency. Is your salary based on daily, weekly, semi-weekly, or monthly?

Then define your civil status. It highly affects the tax status meaning Philippines. Table A is for single and married individuals without any children. Table B is for single and married individuals with dependent children.
- Status ME1/S1 – has 1 qualified dependent
- Status ME2/S2 – has 2 qualified dependent
- Status ME3/S3 – has 3 qualified dependent
- Status ME4/S4 – has 4 qualified dependent

Based on the table you belong to, find the highest amount which does not exceed your taxable income.
Going back to the example above:
- Monthly Basic Pay = P15,000
- Total Deductions = P832.50
- Taxable Income = P14,167.50
- Civil Status: Single or S/ME
- Dependent: none
- Income: Monthly

The 10,000 is the highest amount, not exceeding the taxable income. It falls in the 5th column.
Withholding Tax
- 708.33 + [(P14,167.50 – 10,000) X 20%]
- 708.33 + [(4, 167.50) x 20%)]
- 708.33 + 833.4
- P1,541.73
Let’s have another example:
You are earning P7,000 every two weeks without any deductions. Therefore your taxable income is still P7,000. You are married with one child.
- Semi-Weekly Basic Pay = P7,000
- Total Deductions = none
- Taxable Income = P7,000
- Civil Status: Married with 0ne (1) dependent

The 6,042 is the highest amount, not exceeding the taxable income. It falls in the 5th column.
Withholding Tax
- 354.17 + [(P7,000 – 6,042) X 20%]
- 354.17 + [(958) x 20%)]
- 354.17 + 191.6
- P545.77
