This is a sandbox testing service for “Form IR21 Submission” API. It allows software developers to incorporate within their payroll software the feature for employers to validate and submit Form IR21 (Notification of a Non-Citizen Employee’s Cessation of Employment or Departure from Singapore) to IRAS directly for tax clearance purpose.

It is designed to mimic the functions of the actual “Form IR21 Submission” API so that software developers can test the API integration before subscribing to the actual API.

Developers will need to submit test data based on a pre-defined set of testing scenarios. A submission reference number will be provided within the API response for every successful submission. You can refer to IRAS website for more information on the validation test and the specifications for this API service.
