How Withholding Tax Works in the Philippines

Withholding tax is the Philippine government's method of collecting income tax at the source. Instead of paying your entire annual tax bill in one lump sum, your employer deducts a portion of your salary every payday and sends it directly to the Bureau of Internal Revenue (BIR).

Think of it as a “pay-as-you-earn” system. By the end of the year, most of your income tax obligation has already been collected through these regular deductions.

Most employees in the Philippines are subject to withholding tax. However, these groups are exempt:

• Minimum wage earners — those receiving only the statutory minimum wage for their region are exempt from income tax regardless of the amount.
• Employees earning PHP 250,000 or less per year — under the TRAIN Law, the first PHP 250,000 of annual taxable income is tax-free.

Self-employed individuals and freelancers also pay income tax but through a different mechanism (quarterly filings via BIR Form 1701Q).

The basic formula is:

Follow these steps:

1. Determine annual gross compensation. Multiply your monthly basic salary by 12 and add other taxable benefits (overtime, commissions, etc.).
2. Subtract mandatory deductions. Deduct your employee share of SSS, PhilHealth, and Pag-IBIG contributions. This gives you your taxable income.
3. Locate your tax bracket in the TRAIN Law table above.
4. Apply the formula. Take the base tax for your bracket, then add the tax rate multiplied by the amount your income exceeds the bracket floor.
5. Divide by 12 (or by the number of pay periods) to get your monthly withholding tax.

Employers use the BIR's Revised Withholding Tax Table to determine how much to deduct from each payroll. The amount depends on the employee's pay frequency (monthly, semi-monthly, weekly, or daily) and their taxable compensation for that period.

At year-end (usually in December), the employer performs an annualization: they compute the actual annual tax based on total compensation, compare it to the total amount already withheld, and either refund the excess or collect the shortfall through the final payroll.

• Forgetting to subtract mandatory contributions. Your taxable income is your gross pay minus SSS, PhilHealth, and Pag-IBIG. Using gross pay directly will overestimate your tax.
• Confusing the tax rate with the effective tax rate. If you fall in the 15% bracket, it does not mean 15% of your entire income goes to tax. Only the amount exceeding PHP 250,000 is taxed at 15%.
• Not accounting for 13th-month pay and bonuses. Under the TRAIN Law, the first PHP 90,000 of 13th-month pay and other benefits is tax-exempt. Any excess is added to your taxable income.
• Not filing BIR Form 2316. Even if your employer handles withholding, make sure you receive your Certificate of Compensation Payment/Tax Withheld (BIR Form 2316) every year for your records.
• Assuming minimum wage = automatic tax exemption. You are only exempt if your pay is exactly the statutory minimum wage. If you receive any amount above minimum wage (such as night differential or overtime beyond legal limits), the excess may be taxable.
