From 1 Jan 2020, if you are a local business with an overseas branch/ head office, you are required to register for GST under the Overseas Vendor Registration (OVR) regime in Singapore if your overseas branch/ head office:
(i) has an annual global turnover exceeding S$1 million; and
(ii) makes B2C supplies of digital services exceeding S$100,000 to non-GST registered customers in Singapore. From 1 Jan 2023, you will also have to include B2C supplies of non-digital services (i.e. in addition to digital services) as well as low-value goods.
Under the OVR regime for low-value goods, GST only applies to low-value goods imported into Singapore via air or post. If you are unable to determine at the point of sale the mode of shipment of the goods, please also submit the “Application to Charge GST on LVG Imported via sea/land” at https://go.gov.sg/lvg-imported-via-sea-land immediately after submitting this application.
