FAQs

The tax consultant handles expatriates’ employment income information. Can this information be excluded from the electronic submission?

Employers must submit the employment income information of all employees, including expatriates and directors who receive director's fees, unless the director is a non-resident director who received only director's fees.

Employers should authorise their tax consultants via Corppass to submit the employment income information of expatriates.

Can we submit hardcopy IR8A if we are already in the scheme?

No. AIS participating organisations must submit all employees' employment income information electronically.

How do employers determine the number of employees for compulsory AIS participation? (E.g., number of employees at the beginning of the year or end of the year)

In determining the number of employees for AIS participation, employers should include the total number of employees in the year (e.g., 1 Jan 2024 to 31 Dec 2024 for YA 2025), including employees who had left the organisation during the year. However, in submitting the employment income information of employees, employer should exclude employees for whom tax clearance had been sought.

Employers who have been identified by IRAS to join the AIS will receive a notification letter. Employers who fall within the gazette under S68(2) of the Income Tax Act (PDF, 128 KB) but have not received any notification for YA 2025 should come forward and register for AIS by 31 Dec 2024. Employers who missed the registration deadline of 31 Dec may register for the next Year of Assessment between Apr to Dec 2025.
