Fraudulent emails are currently in circulation that are falsely sent on behalf of the FTA. These emails ask you to update your tax details or contain purported surveys designed to gather personal information. Official emails from the FTA are sent exclusively from addresses ending in @admin.ch or a corresponding subdomain of @***.admin.ch. Please ignore any suspicious messages, do not open any attachments, do not click on any links and do not disclose any personal details. Thank you for your vigilance.
