Joining AIS for Employment Income: YA 2027 Registration

AIS is compulsory for employers with five or more employees from YA 2022, and for other employers covered by the relevant notice or registration rules. Participation continues after headcount falls.

Source checked · 11 October 2026

Count employees and register

Count employees across the year, including leavers and the specified directors, board members, pensioners and non-resident employees. Smaller employers may join voluntarily, after hiring at least one employee. Registration is now available year-round, with YA 2027 registration open until 1 March 2027. Registration in January–1 March permits the current or next YA choice.

Portal roles and ongoing submission

Registration routes are Personal Tax, Company/Business Tax or Tax Agent login; the latter routes require the stated existing IRAS preparer or approver role. Keep the acknowledgement. Once registered, annual electronic submissions are mandatory and hardcopy reporting cannot replace AIS. Income already subject to tax clearance is excluded from the submission under the stated rules.
