This step is required if your business is e-Filing its GST return for the first time or when you want to authorise/re-authorise a person for e-Filing.
Log in to e-Services Authorisation System (EASY) using your business' Access Code and your SingPass / IRAS PIN to authorise yourself, a staff or a third party (e.g. tax agent) for e-Filing. If your Access Code is misplaced or has expired, please fax/mail us your completed Access Code application form (113KB).

If you are a GST-registered sole-proprietor, or under GST Group or Divisional registration, you will need to set up a GST CorpPass Admin account under your GST registration number.
The GST CorpPass Admin account can only be used to authorise staff or third-parties to access IRAS’ GST e-Services and is different from the CorpPass Admin account which may have already been set up under your business’ UEN for other government digital services.
Complete the relevant form below to appoint new GST CorpPass Admin or make changes to your existing GST CorpPass Admin. Send the form to IRAS as a pdf attachment via myTax Mail (click on "Email Us" after logging into myTax Portal) at least 5 working days in advance. - For GST-registered Sole-proprietor (appointment of second administrator only) - For Group/Divisional GST registration
All GST-registered sole-proprietors and group/divisional GST registrants will receive an email by Aug 2018 for the creation of their GST CorpPass Admin accounts.
Once you are authorised, you can log in to myTax Portal for "Organisation/ Business Tax Matters" to retrieve your organisation's GST return (e.g. GST F5).
You can log in to myTax Portal using your SingPass or IRAS PIN.
CorpPass will be the ONLY login method. You will need a CorpPass account to log in to myTax Portal to file your GST returns.
