How to Prepare Your BIR Annual Information Return Philippines

If you have employees or pay other people for services, one specific filing wraps up your entire year of withholding tax activity into a single return. The BIR Annual Information Return Philippines requirement covers exactly this, summarizing every peso of tax you withheld throughout the year for the BIR to review. The short answer is that preparing this return well ahead of its deadline saves you from a stressful scramble every January. Here is everything you need to get it right.

What This Return Covers and Who Needs to File

The Annual Information Return summarizes all the withholding tax you collected and remitted during the year, tying together every monthly and quarterly filing into one comprehensive report. Annual return employer Philippines obligations mainly involve three versions of this return: Form 1604-C for compensation withheld from employees, Form 1604-F for final withholding taxes, and Form 1604-E for expanded withholding taxes on payments to suppliers and professionals.

This applies to any employer withholding tax on employee compensation, and to any business acting as a withholding agent on payments to contractors, professionals, or suppliers. If you have even one employee or one supplier you withhold tax from, you generally need to file the corresponding version of this return.

Our employer BIR guide covers the broader responsibilities tied to having staff. Since this return depends heavily on the same data, our BIR Form 1604C guide walks through that specific filing in more depth.

Step-by-Step: Preparing Your Annual Information Return

Here is exactly how to get this return ready and filed correctly.

Gathering Your Data

1. Reconcile your monthly withholding tax filings, such as BIR Form 1601-C or 0619-E, against your actual payroll and supplier payment records for the full year.
2. Complete year-end annualization for every employee, calculating their total taxable compensation and tax due for the year.
3. Gather every employee and payee’s TIN, full name, address, and total compensation or income paid during the year.
4. Download the current Alphalist Data Entry and Validation Module from the BIR eBIRForms page.

Preparing and Filing the Return

1. Encode every employee or payee’s details into the Alphalist module, double-checking TIN accuracy to avoid validation errors.
2. Validate your alphalist within the module, then generate your .DAT file for attachment.
3. Open the applicable annual return, either 1604-C, 1604-F, or 1604-E, in the eBIRForms Offline Package, and enter your year-end totals.
4. Confirm every figure matches your alphalist exactly, since mismatches are a common cause of rejected submissions.
5. Submit the form along with your attached alphalist .DAT file, then save your confirmation or acknowledgment receipt as proof of filing.

Annual Information Return Deadlines Table

Form	What It Covers	Typical Deadline
BIR Form 1604-C	Annual return on compensation withheld from employees	January 31 of the following year
BIR Form 1604-F	Annual return on final withholding taxes	January 31 of the following year
BIR Form 1604-E	Annual return on expanded withholding taxes	March 1 of the following year
Alphalist of Employees and Payees	Required attachment listing every employee or payee	Filed together with the corresponding form

Verify the latest deadline with the BIR website or ask BB for the most current information, since these dates can shift slightly if they fall on a weekend or holiday.

How to Pay Any Related Withholding Taxes via GCash

This annual return itself typically has no payment attached, but any related monthly or quarterly withholding remittances do.

1. Confirm your outstanding withholding tax due from your monthly or quarterly filings tied to the annual period.
2. Go to the BIR online payment portal and select GCash as your payment channel.
3. Enter your TIN, the form type, and the applicable tax period.
4. Confirm the amount and complete payment through your GCash app.
5. Save your payment confirmation, since your annual return totals should align with everything you already remitted throughout the year.

Keeping your monthly remittance confirmations organized all year makes your January and March reconciliation much faster.

Common Mistakes When Preparing This Return

These errors cause rejected submissions or unwanted BIR attention.

1. Using an outdated version of the Alphalist Data Entry Module, which can trigger validation errors.
2. Letting your annual return totals not match your alphalist figures exactly, down to the peso.
3. Confusing which version of the return applies, filing 1604-C when your situation actually calls for 1604-E as well.
4. Waiting until the last week of January or February to start reconciling a full year of withholding data.
5. Forgetting that employees also need their BIR Form 2316 issued by the same January 31 deadline as your 1604-C filing.

A Filipino Example: Leo’s Small Logistics Company in Rizal

Leo runs a small logistics company in Rizal with 10 employees, paying a combined ₱320,000 in monthly compensation. He also pays several independent truck maintenance contractors subject to expanded withholding tax throughout the year.

In early January, he downloaded the current Alphalist module and encoded his 10 employees’ annual compensation details for his 1604-C filing, validating the file and catching one TIN typo before generating his final data file. He submitted this alongside his employees’ Form 2316 certificates by January 25.

For his contractor payments, Leo prepared a separate alphalist tied to his 1604-E filing, giving himself until early February to reconcile those figures well ahead of the March 1 deadline.

Final Thoughts

Preparing your BIR Annual Information Return Philippines filing really comes down to three habits. Reconcile your withholding data against what you already remitted, validate your alphalist before touching the form itself, and file each version, 1604-C, 1604-F, or 1604-E, by its own specific deadline.

Starting your data reconciliation early in January instead of the final days turns this from a stressful scramble into a routine task. BB is available 24/7 if a specific version or validation error has you stuck. Get your figures organized now, and this filing season will be far less painful.
