Access and entity closure
Authorised company staff and authorised staff of its tax agent can view notices for their authorised YAs. A struck-off company or non-surviving amalgamating entity ceases to exist and loses Corporate Tax digital service access. Download necessary notices before ACRA strike-off or amalgamation.
Available documents and authorisation dates
The service displays filing acknowledgements and most IRAS-issued letters, including Certificates of Residence and Notices of Assessment. Staff counts vary by authorised YAs. Tax-agent staff see documents issued from the firm’s authorisation date: firm authority from 1 January 2022 means notices from that date; firm authority from 15 September 2021 remains that starting date even if an individual employee was authorised only on 1 January 2022.
Read status and service limits
Read/unread status belongs to the company or tax agent, not each staff member. A document read by any authorised staff is read for that company or agent and cannot be reset to unread. The service cannot forward documents, reply to letters, display messages you sent to IRAS or delete notices. Use the upper-left print or save icon to retain a local copy.
Historical viewing window
The 18 May 2022 edition states the current year plus three previous years, illustrated by 2022 and 2019–2021. This is the source’s historical window, not a promise that all older assessments remain accessible indefinitely.
