Upon tax clearance, any existing GIRO instalment plan you have with IRAS will be terminated. If the monies withheld by your employer are insufficient to cover your income tax balance, you are required to pay the shortfall as stated in your Income Tax Bill Overview letter within 7 days of the date of the letter, via other electronic payment modes.

However, if you will be re-employed by another Singapore employer immediately after your cessation of employment and wish to continue paying your income tax via GIRO instalments, please email us your request along with the required documents at myTax Portal  using your Singpass or Singpass Foreign user Account (SFA).
