What Businesses Need to Know (RMC No. 110-2025)
The Bureau of Internal Revenue (BIR) continues its push toward digitalization with the release of Revenue Memorandum Circular (RMC) No. 110-2025, announcing the availability of the 2026 BIR Interactive Tax Calendar on the official BIR website RMC No. 110-2025.
This initiative is designed to help taxpayers stay on top of their tax obligations by providing a centralized, user friendly reference for all recurring tax deadlines throughout the year.
What Is the 2026 BIR Interactive Tax Calendar?
The 2026 BIR Interactive Tax Calendar is an online tool that consolidates monthly tax filing and payment deadlines for various taxes, including:
- Income Tax
- Withholding Tax
- Value Added Tax (VAT)
- Percentage Tax
- Excise Tax
- Documentary Stamp Tax
- Other recurring tax obligations and required submissions
Instead of relying on printed calendars or manually tracking deadlines, taxpayers can now access an updated digital reference anytime.
Key Features Businesses Will Find Useful
Beyond deadlines, the Interactive Tax Calendar includes several practical features that simplify compliance:
1. Direct Access to BIR Forms
Each tax obligation is linked to the corresponding BIR form, allowing users to quickly identify and download the correct document.
2. Required Attachments and Reports
The calendar guides taxpayers on the necessary schedules, attachments, and supporting documents required for each tax return.
3. Updated BIR Directory
Users can access the latest contact details and addresses of BIR offices, including the names of the Head and Assistant Head of each office.
4. Authorized Agent Banks (AABs)
The tool links to an updated list of banks authorized to accept tax payments, reducing confusion during payment.
5. Official BIR Social Media Channels
Taxpayers are redirected to verified BIR social media accounts for official announcements and updates.
6. Guide on How to Use the Interactive Calendar
A built in guide helps users navigate the platform efficiently, even for first time users.
No More Printed BIR Tax Calendars
As part of the BIR’s digital transformation and cost saving efforts, the printing of physical BIR tax calendars has been officially discontinued. All taxpayers are now encouraged to rely on the online Interactive Tax Calendar as their primary reference.
What This Means for Business Owners
While the tool makes deadlines easier to track, it does not remove the responsibility of ensuring correct tax filing, accurate computations, and complete documentation. Missing deadlines or submitting incorrect forms can still result in penalties, surcharges, and interest.
The Interactive Tax Calendar is best viewed as a support tool, not a substitute for proper tax planning and professional advice.
