Important Information for Employers

Employees who have sought tax clearance (Form IR21)

Employers are not required to submit the details of employees’ income information for employees who have sought tax clearance. However, if there are additional income for these employees, please submit an additional IR21.

Sole Proprietors and Partners

As Sole-Proprietors and Partners are owners of their own businesses, the salaries drawn from the businesses are taxable as trade income. The income information of these sole-proprietors and partners should be excluded via the Auto-Inclusion Scheme.

Exception
The income information of partners who are engaged under an employment contract with the partnership should be submitted as employment income via the Auto-Inclusion Scheme. Generally, these partners do not assume the liabilities of the partnership and they do not have a share in the profit/ loss of the partnership. They are considered employees of the partnership even though they have the title of ‘partner’.

Non-resident Directors

Employers under AIS have to declare the employment income information of all their employees, including non-resident directors. If Section 45 withholding tax has been paid on director’s fees payable to a non-resident director, indicate select ‘Y’ under ‘Section 45 (applicable to non-resident director) Indicator’ when reporting via AIS. 

Employees Posted Overseas

You are not required to submit their information only when the non-resident director solely receives director’s fees.

As of 1 Jan 2004 (Year of Assessment 2005):

  • remittance from overseas employment is not taxable;
  • any excess CPF contribution by the employer is not taxable; and
  • employee’s CPF contribution is also not deductible
  • Overseas posting incidental to Singapore employment

Employees Rehired within a Year

When an employee leaves and re-joins the organisation in the same year, please consolidate the employment income information and submit as one record.

Trainees and Students on Attachment

Employers must submit the employment income information for students who enter into an employment contract with the employer in Singapore and remuneration is paid for the services rendered.
