Every employer in the Philippines has responsibilities that extend beyond paying salaries. Employers also act as withholding agents of the government, tasked with withholding, remitting, and reporting income taxes on compensation paid to employees. One of the most important year-end tax compliance requirements is the filing of BIR Form No. 1604-C, the Annual Information Return of Income Taxes Withheld on Compensation.
Although many employers diligently remit monthly withholding taxes, mistakes often occur during the annual reconciliation process. Incorrect employee information, unreconciled payroll records, and missed deadlines can result in penalties, employee tax issues, and unnecessary Bureau of Internal Revenue (BIR) inquiries.
This guide explains BIR Form 1604-C, who is required to file it, the filing procedures, compliance deadlines, and common mistakes employers should avoid.
What Is BIR Form 1604-C?
BIR Form No. 1604-C is the Annual Information Return of Income Taxes Withheld on Compensation and Final Withholding Taxes.
It is the annual report filed by employers to summarize:
- Compensation paid to employees;
- Taxes withheld from employee salaries;
- Taxes remitted to the Bureau of Internal Revenue (BIR); and
- Other information required under applicable BIR regulations.
The return serves as the annual reconciliation of the employer’s payroll tax obligations.
Why Is BIR Form 1604-C Important?
The BIR uses Form 1604-C to verify that:
- taxes withheld from employees have been properly remitted;
- payroll records agree with monthly withholding tax returns;
- employees receive accurate Certificates of Compensation Payment/Tax Withheld;
- compensation income reported by employees matches employer records.
Accurate reporting protects both the employer and its employees from future tax issues.
Who Is Required to File BIR Form 1604-C?
Generally, every employer required to withhold taxes on compensation must file BIR Form 1604-C.
This includes:
- Sole proprietorships with employees
- Partnerships
- Domestic corporations
- Resident foreign corporations
- Branch offices
- Representative offices with employees
- Government agencies
- Government-owned and controlled corporations (GOCCs)
- Non-stock and non-profit organizations with employees
Even if only a small number of employees are involved, employers with compensation withholding obligations are generally required to comply.
What Information Is Reported?
Although the exact format may be updated through future BIR issuances, Form 1604-C generally includes:
- Employer information
- Taxpayer Identification Number (TIN)
- Registered business address
- Total compensation paid during the year
- Total compensation tax withheld
- Monthly withholding tax remittances
- Employee information
- Applicable schedules and attachments
The annual return should reconcile with payroll records and previously filed monthly tax returns.
Relationship Between Form 1604-C and Payroll Taxes
Every payroll period, employers compute:
- Gross compensation
- Mandatory deductions
- Taxable compensation
- Compensation tax to be withheld
The withheld taxes are then remitted to the BIR.
At year-end, Form 1604-C consolidates these payroll withholding activities into one annual report.
Relationship Between Form 1604-C and BIR Form 2316
One of the most important responsibilities of employers is the preparation of BIR Form No. 2316 (Certificate of Compensation Payment/Tax Withheld) for employees.
BIR Form 2316
Issued to each employee showing:
- Total compensation received
- Taxes withheld
- Employer information
- Employee information
Employees use this certificate for:
- substituted filing, where applicable;
- annual income tax compliance;
- loan applications;
- visa applications;
- employment verification.
The information reported in Form 2316 should be consistent with the employer’s Form 1604-C.
Filing Procedures
Step 1: Reconcile Payroll Records
Before preparing Form 1604-C, employers should reconcile:
- Payroll registers
- Monthly withholding tax returns
- General ledger accounts
- Compensation expense accounts
- Tax remittance records
Any discrepancies should be resolved before filing.
Step 2: Verify Employee Information
Review each employee’s:
- Name
- Taxpayer Identification Number (TIN)
- Employment status
- Compensation records
- Taxes withheld
Incorrect employee information may result in reporting errors and compliance issues.
Step 3: Prepare BIR Form 2316
Ensure that each employee receives an accurate BIR Form 2316 reflecting:
- Total compensation;
- Taxes withheld;
- Correct employer and employee information.
The figures should match the employer’s annual records.
Step 4: Complete BIR Form 1604-C
Prepare the annual return using the reconciled payroll information and withholding tax records.
Review all totals carefully before submission.
Step 5: Submit the Return
Employers should file Form 1604-C using the filing method prescribed by the BIR, including electronic filing where required.
Always verify the current filing procedures applicable to your taxpayer classification.
Filing Deadline
BIR Form 1604-C is generally required to be filed on or before January 31 of the year following the calendar year, together with the required alphabetical list of employees, where applicable.
Employers should consult the latest BIR issuances to confirm current filing procedures and documentary requirements.
Employee Compliance Responsibilities
Although the employer prepares Form 1604-C, employees also benefit from accurate reporting.
Employees should verify:
- Correct spelling of their names
- Accurate TIN
- Correct compensation reported
- Proper taxes withheld
- Receipt of BIR Form 2316
Errors discovered early are easier to correct before annual filing.
Common Employer Mistakes
Many employers experience compliance issues because of avoidable errors.
1. Incorrect Employee Information
Mistakes involving:
- TINs;
- names;
- employment dates;
may create discrepancies in BIR records.
Employers should verify employee information regularly.
2. Failure to Reconcile Payroll Records
Annual totals should agree with:
- payroll registers;
- monthly withholding tax returns;
- accounting records;
- compensation expense accounts.
Differences often trigger BIR inquiries.
3. Incorrect Tax Withholding
Errors in payroll tax computation may result in:
- under-withholding;
- over-withholding;
- employee tax deficiencies;
- employer penalties.
Periodic payroll reviews reduce these risks.
4. Late Filing
Failure to submit Form 1604-C on time may result in:
- surcharge;
- interest;
- compromise penalties;
- administrative sanctions.
Maintaining a compliance calendar is essential.
5. Failure to Issue BIR Form 2316
Employers should furnish employees with their BIR Form 2316 within the period prescribed by BIR regulations.
Failure to do so may create compliance problems for employees who need the certificate for tax or employment-related purposes.
Best Practices for Employers

Consequences of Non-Compliance
Failure to comply with compensation withholding tax requirements may expose employers to:

- BIR audit findings;

Accurate annual reporting protects both the employer and its workforce.
