API Enhancement Notice
(Updated as of 24/01/2022)
The Check GST Register API will be enhanced in the later part of 2022 to let you know whether a GST-registered business is currently registered under the Simplified Pay-only Regime, which is applicable to overseas suppliers and electronic marketplace operators under the Overseas Vendor Registration Regime.
The enhancements will involve new data element(s) to be introduced in the response payload, and depending on how your software is designed, these enhancements may require some changes to your software.
