Computing for Withholding Tax on Compensation is one of the most critical regulatory requirements for employers in the Philippines. The Bureau of Internal Revenue (BIR) mandates that employers withhold the correct amount of tax from their employees' salaries and remit it to the government monthly. Failure to do so can result in hefty penalties. This guide breaks down the correct methodology for computing taxes under the current TRAIN Law.
1. Understanding the TRAIN Law Tax Brackets
Since the implementation of the Tax Reform for Acceleration and Inclusion (TRAIN) Law, employees earning a taxable income of PhP 250,000 and below annually are exempt from withholding tax. For those earning above this threshold, the BIR provides specific tax tables categorized by payroll frequency (Daily, Weekly, Semi-Monthly, and Monthly).
Starting January 1, 2023, the tax rates were further reduced, providing higher take-home pay for most employees. The current brackets range from 15% to 35% depending on the income level.
2. Step-by-Step Tax Computation
To accurately compute the withholding tax, you must first determine the exact amount of money that is actually subject to tax. This is called the Net Taxable Income.
Step A: Determine Gross Pay
Include the basic salary, overtime pay, holiday pay, night differential, and any taxable allowances or bonuses.
Step B: Deduct Non-Taxable Items
Not all income is taxed. You must deduct the following to get the Net Taxable Income:
- Statutory Deductions: The employee's share of SSS, PhilHealth, and Pag-IBIG contributions are strictly non-taxable.
- De Minimis Benefits: Allowances that meet BIR's specific criteria (e.g., rice allowance up to PhP 2,000/month, uniform allowance up to PhP 6,000/year, medical cash allowance) are exempt from tax.
- Late and Absence Deductions: Deductions for missed work hours reduce the gross pay and, consequently, the taxable base.
Formula: Gross Pay - Non-Taxable Allowances - Statutory Deductions - Lates/Absences = Net Taxable Income.
Step C: Apply the BIR Tax Table
Once you have the Net Taxable Income, locate the correct bracket in the BIR Withholding Tax Table (e.g., the Semi-Monthly table). Find the row where the Net Taxable Income falls.
Computation: Tax = Prescribed Minimum Tax + [ (Net Taxable Income - Compensation Level/Bracket Base) x Bracket Percentage ]
3. The 13th Month Pay and Other Bonuses
Under Philippine law, the 13th-month pay and other benefits (like productivity bonuses or Christmas bonuses) are tax-exempt up to a total of PhP 90,000 per year. Any amount exceeding this PhP 90,000 threshold must be added to the employee's gross taxable income and subjected to withholding tax in the payroll period it was given.
4. Year-End Tax Annualization
In December, or when an employee resigns, employers must perform an "Annualization" process. Because monthly withholding is just an estimate based on a single month's salary, fluctuations (like unpaid leaves, sudden promotions, or taxable bonuses) can cause the withheld amount to be slightly inaccurate over the course of a year.
During annualization, the employer totals the actual gross taxable income for the entire year, computes the exact true annual tax due using the Annual Tax Table, and compares it to the total tax already withheld from January to November. The difference is then either deducted from or refunded to the employee in their final pay for the year. This ensures that the BIR Form 2316 (Certificate of Compensation Payment/Tax Withheld) perfectly balances to zero.
