Philippines Tax Calendar 2026 | Ascentium Philippines

The Bureau of Internal Revenue (BIR) annually releases deadlines for tax reporting, submission, filings, and reportorial requirements from Philippine government agencies for individual and corporate taxpayers in the Philippines. Foreign and local business owners must respect and adhere to the deadlines to continue operating their businesses lawfully in the Philippines.

We offer a comprehensive list of essential deadlines to help your company stay current and meet applicable tax deadlines with the BIR.

Our tax calendar includes:

Tax Returns and Remittance Forms
List of Requirements (for tax filings)
National and Special Non-Working Holidays
List of Authorized Agent Banks (AABs)

This calendar is a general source of information for all taxpayers seeking to file their tax filings on or before the due dates, referencing BIR’s online tax calendar.

A Philippine tax calendar is a schedule of important tax filing and payment deadlines that businesses need to monitor throughout the year. It helps companies keep track of recurring obligations to the BIR, including monthly, quarterly, and annual submissions. Using one makes it easier to stay organized and avoid missed deadlines.

Monthly tax deadlines often involve recurring tax filings and related payment obligations required by the BIR. The exact forms and due dates depend on the nature of the business, its registration, and the taxes it is required to file. Because monthly obligations can come quickly, businesses should review their compliance calendar at the start of each month.

Quarterly deadlines usually cover tax filings that are submitted every three months, such as certain income tax and percentage tax obligations, depending on the taxpayer’s profile. These deadlines are important because they support year-round compliance and help businesses track their tax position before annual filings.

Annual tax deadlines often include year-end reporting and income tax compliance requirements. These filings usually require more complete financial records, reconciliations, and supporting schedules than monthly or quarterly submissions.

A business should seek professional tax support when its filing obligations become more complex, deadlines are hard to manage, or internal records need review before submission. This is also helpful for new companies, foreign-owned entities, and businesses handling multiple tax types.
