On 22 October 2026, IRAS announced a planned service downtime for the myTax Portal from 16 to 28 December 2026 to implement system enhancements. During this period, digital services including corporate and individual tax filing, GST returns, and property tax transactions will be progressively unavailable. Taxpayers and tax agents are advised to complete time-sensitive submissions before the maintenance window or immediately after services resume.
Key Takeaways
- Extended Year-End Maintenance Window: The 13-day downtime coincides with critical year-end filing deadlines, requiring proactive planning for GST F5/F8 returns and corporate tax computations.
- Phased Service Restoration: IRAS indicated services will be restored progressively, meaning some functions may remain offline longer than others; users should monitor the IRAS website for real-time updates.
- Alternative Filing Arrangements: Taxpayers unable to meet deadlines due to the outage should document their attempts and contact IRAS for administrative concessions, though statutory deadlines remain legally binding unless formally extended.
