When a non-Singapore Citizen employee ceases employment, goes on an overseas posting, or plans to leave Singapore for more than three months, employers must notify IRAS at least one month in advance and withhold all monies due to the employee from the date of awareness. This process is known as tax clearance and applies to all work pass holders as well.
