Tax Annualization in the Philippines: FAQs for Employers

With December being the last payroll month of the year, employers in the Philippines must carry out year-end payroll adjustments, also known as tax annualization, as part of their compliance obligations. This ensures that every employee’s total taxes for the year are accurately computed and correctly filed with the Bureau of Internal Revenue (BIR).

For SMEs, founders, and HR or Payroll managers, this process can be stressful. It requires adjustments to employee tax withholdings, proper employee classification, and strict compliance with Philippine tax law and BIR deadlines. Mistakes can trigger penalties, payroll disputes, and employee dissatisfaction.

To help SMEs navigate tax annualization in the Philippines, we’ve put together answers to the most frequently asked questions.

1. What is Tax Annualization?

Tax annualization is the process of computing the actual income tax due of each employee for the entire year and reconciling this with the taxes already withheld from their salaries.

At year-end, employers must:

  • Adjust employee tax withholdings to reflect their actual income.
  • Identify whether an employee has overpaid (eligible for a refund) or underpaid (additional tax must be withheld).

Why it matters for employers:
Tax annualization ensures full BIR compliance, protects your business from penalties, and maintains employee trust by avoiding sudden deductions or delays in refunds.

2. Why do employees sometimes receive large deductions or refunds at year-end?

Year-end payroll adjustments may result in either:

  • Additional tax deductions – if the total annual tax due is higher than the amount withheld during the year.
  • Tax refunds – if the total annual tax due is lower than the tax already withheld.

This usually happens when:

  • The employee received salary increases, bonuses, or commissions during the year
  • The employee transferred employers mid-year
  • Incorrect withholding tax brackets were applied in earlier months

For employers, these discrepancies can lead to employee relations issues, with staff questioning sudden deductions or delayed refunds. By carrying out proactive and accurate annualization, SMEs can ensure BIR compliance while maintaining transparency and employee trust.

3. How do I compute annualized tax?

Employers must:

  1. Consolidate the employee’s total taxable income for the year.
  2. Apply the BIR’s latest income tax table to determine the total annual tax due.
  3. Deduct the tax already withheld during the year.
  4. Collect any shortfall or release refunds in the December payroll.


Formula for Annual Tax Due:

Annual Tax Due = (Total Net Taxable Income × Applicable Tax Rate)

Taxable Income Includes:

  • Regular salary
  • 13th month pay (above the ₱90,000 exemption)
  • Commissions, allowances, other benefits

Example:

If the net taxable income is Php450,000 for the entire year, the tax due will be Php 32,500

Annual Tax Due = Php 22,500 + 20% (Php450,000 – Php 400,000)
= Php 22,500 + 20% (Php 50,000)
= Php 22,500 + Php 10,000
= Php 32,500

4. Which employees are covered, and what should employers file?

Correct employee classification is critical for compliance as employers who misclassify employees risk BIR penalties and employee disputes.

  • Substituted Employees – Employees who had only one (1) employer for the entire year and no other source of income.
    • Employers must file BIR Form 2316 on their behalf.
    • Employees don’t need to file their own income tax return as they are covered by substituted filing.
  • Non-Substituted Employees –Employees with two or more employers in a year or other sources of income (e.g., freelance, professional services, business)
    • The employer must still issue Form 2316.
    • Employees must file their own Annual ITR (BIR Form 1700/1701), in addition to the employer’s filing.

Here’s A Quick Decision Flow for Employers:

5. What is BIR Form 2316?

BIR Form 2316 (Certificate of Compensation Payment/Tax Withheld) is the official document that summarizes each employee’s total income earned or compensation paid and taxes withheld during the year and remitted to the BIR.

Employers are required to:

  • Issue and provide signed copies of BIR Form 2316 to employees by January 31 of the following year.
  • Submit certified copies to the BIR by February 28 (for substituted employees only)

6. What are the important deadlines for tax annualization?

Employers in the Philippines must follow strict BIR deadlines to remain compliant. Missing these can result in penalties, employee disputes, or unnecessary backlogs.

Key Deadlines for Employers (BIR Requirements):

  • December – Conduct tax annualization adjustments in the last payroll cycle.
  • January 31 – Issue signed BIR Form 2316 to employees.
  • February 28 – Ensure all BIR Form 2316 are signed by all employees and submit signed Form 2316 for substituted employees to the BIR.
