Services covered by the authorisation
Published on 23 July 2025, the guide covers filing income tax returns, checking employer income submissions, amending bills, viewing or transferring parenthood tax rebate and requesting a filing extension. The authorisation also covers updating dependent details, viewing individual notices, using myTax Mail, updating contact and notification preferences, paying tax, appealing penalty waivers and viewing account summaries and GIRO plans. Agents can access client mail submitted after the portal refresh; the guide does not promise access to every historical message.
Appointing a tax agent
Log in with Singpass under Personal Tax, then open Profile and Manage Tax Agent Authorisation. Enter the firm’s identification type and tax reference. An agent email is optional but enables timely updates; otherwise inform the agent separately. The start date defaults to the current date, while the end date is optional. Continue to review the particulars and declaration, then submit. Retain the acknowledgement. Processing is stated to take up to 15 minutes, with an SMS or email sent to the taxpayer and an email to the agent where an address was supplied.
Changing the period or email
Use the pencil beside the effective period to amend the end date. The new end date must be today or a future date; backdating is not allowed. Review the change, accept the declaration and submit. To amend an existing agent email, use its edit control, enter the address, accept the terms and save. Where no email is recorded, the guide directs the user to Update Contact and Notification Preferences instead. Confirm the acknowledgement shown after saving.
Terminating an appointment
Select the termination control for the agent and continue through the confirmation screen. Preserve the acknowledgement. The guide expressly states that termination cannot be undone; a period amendment and termination are different actions. Dates displayed in sample screens illustrate the procedure rather than prescribing an appointment term.
