Adding a GST Number

101domain is required to charge a 7% GST on services or goods sold to customers in Singapore that are not registered for GST.

GST, or Goods and Service Tax, is a consumption tax and in general, it is due when goods and/or services are sold and invoiced by the supplier selling goods or services and collected from the customer.  A GST  is a unique identifier assigned to a business or person registered under the GST Act in Singapore. It can be checked at the Inland Revenue Authority of Singapore‚Äôs website. If you can provide a valid GST Number to 101domain before your purchase, 101domain will not charge GST on the next invoice or future invoices issued to you.
