Historical availability and incoming documents
The FAQ last updated 19 October 2023 says the service began 1 February 2008, with older acknowledgements/correspondence unavailable. It states an acknowledgement takes three working days to upload and illustrates a 1 February filing becoming viewable 4 February 2008. It only displays IRAS-sent correspondence, not messages sent to IRAS; the initial document types described are GST registration and cancellation notifications. These historical descriptions should not be presented as a current service catalogue.
Legacy browser and file instructions
The troubleshooting sequence uses Internet Options > Security > Custom Level to enable automatic download prompts, then allows IRAS popups and restarts the browser if needed. It gives Save As instructions for Internet Explorer and Firefox. Notices are PDFs compressed as ZIP files, requiring PDF viewing and unzip capability. References to Windows XP/Vista, old Microsoft support and browser menus are legacy context, not a recommendation to adopt obsolete software or weaken every site’s settings.
Document-management restrictions
The FAQ says notices cannot be deleted, a read item cannot be reset to unread and the system does not onward-forward documents to another party. Saving locally is separately explained. Preserve these distinctions: viewing, saving and built-in forwarding are different functions.
