Employer Obligations as a BIR Withholding Agent
Every employer in the Philippines — including foreign-owned companies — is a withholding agent for income tax on compensation. This means the company is legally responsible for computing the correct tax on each employee’s salary, deducting it at source, and remitting it to the Bureau of Internal Revenue (BIR) on schedule.
The liability sits with the employer. If withholding is incorrect or remittance is late, the company — not the employee — faces penalties, surcharges, and potential compromise assessments.
2026 Tax Bracket Table (Monthly)
The TRAIN Law Phase 2 brackets, in force from January 2023 onwards, continue to apply in 2026. The monthly withholding table is:
| Monthly Taxable Compensation | Tax |
|---|---|
| Up to ₱20,833 | Exempt (₱0) |
| ₱20,834 – ₱33,333 | 15% of excess over ₱20,833 |
| ₱33,334 – ₱66,667 | ₱1,875 + 20% of excess over ₱33,333 |
| ₱66,668 – ₱166,667 | ₱8,541.80 + 25% of excess over ₱66,667 |
| ₱166,668 – ₱666,667 | ₱33,541.80 + 30% of excess over ₱166,667 |
| Over ₱666,667 | ₱183,541.80 + 35% of excess over ₱666,667 |
The ₱20,833 monthly exemption corresponds to the ₱250,000 annual tax-exempt threshold (₱250,000 ÷ 12).
What Is “Taxable Compensation”?
Taxable compensation is not the same as gross pay. Before applying the tax table, employers subtract:
- Employee-share statutory contributions (SSS, PhilHealth, Pag-IBIG) — these are deductible in computing taxable income
- De minimis benefits within current thresholds — raised for 2026 by BIR Revenue Regulation No. 29-2025, effective 6 January 2026: rice subsidy up to ₱2,500/month (was ₱2,000), clothing/uniform allowance up to ₱8,000/year (was ₱6,000), actual medical assistance up to ₱12,000/year (was ₱10,000), laundry allowance ₱400/month (unchanged), and other categories enumerated in the regulation. Use the 2026 figures — several payroll references still cite the pre-2026 ceilings.
- 13th-month pay and other benefits up to the ₱90,000 tax-exempt ceiling — a combined pool covering 13th-month pay, other bonuses, and any de minimis amounts that exceed their individual ceilings above
Getting these exclusions right matters: over-withholding harms employees and creates year-end reconciliation headaches; under-withholding creates BIR deficiency interest.
Semi-Monthly Payroll and Monthly Withholding
If you run a semi-monthly payroll cycle, withholding is still computed and remitted monthly. The standard approach is to annualise each cut’s taxable income, compute the tax, then divide proportionally. Chamberlain handles this correctly across both cuts so the remittance to BIR ties out each month.
BIR Filing Requirements
| Filing | Form | Deadline |
|---|---|---|
| Monthly remittance | BIR Form 1601-C | 10th or 15th of the following month (electronic filers: 15th) |
| Annual information return | BIR Form 1604-C | 31 January of the following year |
| Per-employee certificate | BIR Form 2316 | 31 January of the following year |
BIR Form 2316 must be signed and provided to each employee. For employees with only one employer during the year and whose tax has been correctly withheld, Form 2316 substitutes for the individual income tax return — this is the “substituted filing” arrangement.
Year-End Tax Adjustment
Before 31 December, employers must perform a year-end tax adjustment to true up accumulated withholding against the employee’s actual annual tax liability. Any over-withheld amount is refunded to the employee in the December payroll; any under-withheld amount is collected. Chamberlain handles this reconciliation automatically as part of the annual payroll cycle.

Frequently asked questions
What is withholding tax on compensation in the Philippines?
It is the income tax withheld by the employer from an employee's salary each pay period and remitted to the BIR on the employee's behalf. The employer is a withholding agent — failing to withhold or remit correctly creates direct liability for the company.
What tax rates apply in 2026?
The TRAIN Law (RA 10963) Phase 2 rates apply. Monthly taxable compensation up to ₱20,833 is exempt; income above that is taxed at graduated rates from 15% to 35%, depending on the bracket.
What BIR forms must employers file for withholding tax?
Employers file BIR Form 1601-C monthly and BIR Form 1604-C annually. Each employee must also receive BIR Form 2316 on or before 31 January of the following year, showing total compensation and tax withheld.
