𝗣𝗨𝗕𝗟𝗜𝗖 𝗔𝗗𝗩𝗜𝗦𝗢𝗥𝗬 : 𝗕𝗜𝗥 𝗘𝗫𝗧𝗘𝗡𝗗𝗦 𝗗𝗘𝗔𝗗𝗟𝗜𝗡𝗘 𝗙𝗢𝗥 𝗘𝗔𝗙𝗦 𝗦𝗨𝗕𝗠𝗜𝗦𝗦𝗜𝗢𝗡𝗦 𝗨𝗡𝗧𝗜𝗟 𝗠𝗔𝗬 𝟮𝟱

The Bureau of Internal Revenue (BIR) has announced that it is extending the deadline for the submission of the 2025 Audited Financial Statements (AFS) and other mandatory attachments through the Electronic Audited Financial Statements (eAFS) facility until May 25, 2026.

The extension was finalized through Revenue Memorandum Circular No. 46-2026 to provide administrative relief to taxpayers who encountered eAFS system-related technical issues during the recently concluded 2025 Annual Income Tax Return (AITR) filing season.

Under this issuance, penalties arising solely from delayed attachment submissions during this period are waived.

The extension until May 25, 2026, strictly applies to the following taxpayers:

1. Those who were unable to successfully upload their 2025 AFS and attachments through the eAFS platform on or before May 15, 2026, due to system-related issues; and

2. Those who utilized the contingency email submission route on or before May 15, 2026, but have not yet received an official email acknowledgment receipt from their concerned BIR office.

Taxpayers who submitted their attachments through the prescribed contingency email procedure on or before May 15, 2026, and have already received an email acknowledgment from their concerned BIR office, are considered fully compliant.

They are not required to resubmit via the eAFS facility, though they may still choose to do so voluntarily.

The BIR clarified that this extension applies only to the submission of the AFS and related attachments through the eAFS facility. It does not extend the statutory deadline for the filing and payment of the Annual Income Tax Return (AITR) itself.
