A possible reason is that your effective period of authorisation has ended. If so, you have to delete your authorisation record in EASY and re-authorise yourself again. To allow an unlimited effective period, you may leave the “Effective Date To” as blank during authorisation.
You may download a printable copy of GST e-Filing User Guide (4.47MB) for step-by-step instructions on deleting authorisation record and authorising staff/ third party.
You should ensure that you are authorised for your organisation’s GST matters at e-Service Authorisation System (EASY) and you have selected “My Organisation's/Business' Tax Matters” at the login page.
If you are logging in to myTax Portal on behalf of your client, you should ensure that you are authorised for your client’s GST matters at EASY and you have selected “My Client’s Tax Matters” at the login page.
GST F5 will only be available for e-Filing one day after the end of your accounting period. For example, GST F5 for the accounting period that ends on 31 Dec 2009 will be available from 1 Jan 2010.
If you encounter this problem after the end of your accounting period, you should ensure that you are authorised for your GST matters at e-Service Authorisation System (EASY) and you have selected “My Organisation's/Business' Tax Matters” at the login page.
No. You see a <Submit for Approval> button because you have been authorised as a “preparer” in e-Service Authorisation System (EASY). If you click on the button, your GST F5 will only be submitted to the person who has been authorised as the “approver”. Thereafter, the approver needs to log in to myTax Portal , retrieve the GST F5 for approval and click on <Submit> button for submission to IRAS. The approver will see an Acknowledgement page upon successful submission.
If you had wrongly authorised yourself as a “preparer” (i.e. can only prepare GST return online) instead of an “approver” (i.e. can prepare and submit GST return to IRAS online), you can log in to EASY to change your role. You may refer to the step-by-step instructions on editing authorisation records.
Upon successful submission of your GST F5, you will see an acknowledgement page. Alternatively, you can check under “View return status” at myTax Portal . For step-by-step instructions, you may refer to Check return status. You do not need to call IRAS to get a confirmation.
If you do not see an acknowledgement page and your return status for that accounting period indicates “Pending for approval”, it means that the GST F5 form has only been submitted to the person who has been authorised as the “approver”. For submission to IRAS, please refer to FAQ Q4 above.
If you have forgotten to print the acknowledgement page, you may retrieve the acknowledgement page from “View Correspondence/ Notices” at myTax Portal . It will be available 3 working days after your submission of the GST return. For step-by-step instructions, you may refer to Check acknowledgement page/ correspondence/ notices.
You may request for a GST F7 for the affected prescribed accounting period at myTax Portal to disclose the errors made. Please complete the GST F7 with the revised figures (including all adjustments) for all boxes as it will supercede the previous GST return (GST F5 or a previous GST F7) submitted for the accounting period. For step-by-step instructions on requesting for GST F7, you may download a printable copy of GST e-Filing User Guide (4.47MB).
However, depending on the nature and amount of the error made, you may be allowed to adjust for the error in your GST F5 for the next accounting period. Please refer to Correct errors made in GST return for more details on the conditions.
