Tax calculator: Compute your income tax

MANILA, Philippines (UPDATED) – Wondering how your employer is computing your income tax?

You can calculate it yourself.

In our previous story, we enumerated the items you need to consider in computing your salary tax. (READ: What to consider in computing income tax).

Now, we'll show you how to compute it.

Here's a step-by-step guide for manual computation. You may also use the tax calculator below.

Step 1: Determine your taxable income.

To compute your taxable income, follow this formula:

Taxable income = (Monthly Basic Pay + Overtime Pay + Holiday Pay + Night Differential) - (SSS/PhilHealth/Pag-IBIG deductions - Tardiness - Absences)

Let's say Employee A is married with one dependent, and has a basic monthly pay of P25,000. Based on the tables of government contributions, Employee A will pay:

Employee A's taxable income will therefore be P24,006.20. Here's how it is computed:


Step 2: Using your taxable income, compute your income tax by referring to the Bureau of Internal Revenue (BIR) tax table.

In the BIR table below, look for your pay period (usually it's "Monthly" for employed taxpayers), then your status ("S/ME" means single/married with no dependent, "ME1/S1" means married/single with one dependent, and so on). 

There are 8 columns under each pay period. Under the columns are taxable income amounts and their corresponding tax rates. As the taxable income increases, the tax rate also goes up.

In the row indicating your status, look for the highest amount that does not exceed your taxable income.

Let's use Employee A, with status "ME1/S1," as example. The highest amount that does not exceed Employee A's taxable income of P24,006.20 is P17,917 (ME1/S1 row, Column 6). 

The heading of Column 6 reads "1,875.00 + 25% over."

This means Employee A's tax is P1,875 plus 25% of the difference of his taxable income (P24,006.20) and the amount in the table (P17,917).

Here's the computation:
