Income Tax Return BIR Deadline: What You Need to Know Before You File
The Bureau of Internal Revenue (BIR) has set April 15, 2026 as the deadline for the filing and payment of the Annual Income Tax Return (AITR) in the Philippines. Taxpayers are strongly advised to prepare early to ensure accurate filing, avoid penalties, and prevent system delays during peak submission periods.
Missing the deadline may result in penalties, including surcharges and interest, making early preparation essential for full compliance.

Proper classification is important to determine the correct BIR form and filing requirements.
