Global Daily Tax News, Guernsey Extends Personal Tax Return Deadline, (Dec 1, 2025)

The Guernsey Government has announced an extension to the deadline for filing 2024 tax returns.

The extension, until January 31, 2026, is on account of technical issues with the Revenue Service System in recent weeks, the Government said, stating: "Providing additional time will help ensure the online service is stable and accessible for customers who wish to file digitally."

Nig Garland, Acting Director of Revenue Service, said: "Extending the deadline ensures that everyone has enough time to submit their returns. However, while the deadline has been extended, customers are encouraged to file as early as possible to help reduce pressure on the system and support a smoother flow of processing and assistance. To continue to help customers, the Revenue Service will provide additional support this week at Edward T. Wheadon House, to assist with online registration and submission."
