Find notices rather than acknowledgement pages
In myTax Portal choose Notices/Letters > S45. For Category Notices choose a document type and enter a notice date or date range, which is mandatory; initial non-resident-name characters or a filing acknowledgement number may refine the search. Click Filter. A Confirmation of Payment letter is not issued merely for paying without e-filing the withholding-tax submission: e-file by the due date. The IRAS Website link lists available notice types.
Acknowledgement filters and result pages
Category Acknowledgement offers S45 EFILING E-ACKNOWLEDGEMENT, S45 ODE E-ACKNOWLEDGEMENT and notification-preference acknowledgement. Here the mandatory date/range is submission to IRAS, optional refinement is filing acknowledgement number, and non-resident name is not usable. Only e-file records from 1 June 2020 onward appear. Results show a total and 200 at a time; the Displaying range selector moves to the next group. Notices sort by notice date, acknowledgements by submission date; unread items have a blue left-border line.
Open or download all/selected documents
Select a row to view. The source requires pop-ups to be allowed for viewing/download and illustrates Edge, Chrome and Safari settings. Download retrieves the currently displayed documents; choose another 200-record range and download again to retrieve further groups. Alternatively tick individual checkboxes and use Download Selected. Save the zipped PDF collection locally; the guide describes a 50 MB zipped-PDF file size. Do not assume one displayed-group download contains every search result.
