Business and agent entry points
Business Tax login shows authorised tax-type preferences; use View Details or Account > Profile > Update Notice Preferences. A tax agent uses Tax Agent Login > Business Client, opens the same profile service, selects client ID type such as UEN-LOCAL CO/GSTN, enters the tax reference and Next. A Corppass Approver may update; a Preparer may view only.
Email alerts versus paper notices
Per authorised tax type, choose Email or paper at the registered address. Email allows up to four addresses, each at most fifty characters, and alerts when digital notices become viewable in Notices/Letters. Paper choice sends to registered address without email alerts. The 1 June 2021 guide says changes take effect within seven days; an email alert is not described as the full notice itself.
Apply addresses to all types and save evidence
An Approver authorised for every relevant tax type can use Add this email address to all tax types and Add to populate all available types. Select Save Preference to save, including when editing individually. The acknowledgement is saved the same day in Notices/Letters as Acknowledgement of Notification Preference; use Save As PDF/Print or retrieve it later. Its appearance is distinct from the seven-day effective period.
