Good and Services (GST) Overview
Singapore passed legislation effective Jan 1, 2020, requiring non-resident entities selling digital services to collect and remit a 9% Goods and Services Tax (GST) on its sales to customers located in Singapore. Non-residents are only required to apply GST on Business to Customer (B2C) transactions. Business to Business (B2B) transactions will not be charged GST if a valid GST number is provided by the B2B customer.
When will Twilio SendGrid start charging GST in Singapore?
Twilio Sendgrid will begin collecting GST on services sold to customers located in Singapore starting November 2025.
How can I be tax exempt for GST?
B2B customers will not be taxed with a valid GST number, which should be entered in the Sendgrid Account Details Page. However, B2B customers should self-assess the GST through the reverse charge mechanism.
Question: I am a business, but do not have a GST number. I am not required to register for GST since my business falls under the required sales threshold for registering.
Answer: The GST laws for nonresidents are designed to capture GST from B2C consumers and from B2B consumers that fall under the sales threshold. Unless a B2B customer can provide a valid GST number, they will be considered a B2C and the transaction will be subject to tax. Nonresidents are not required to tax B2B customers with valid GST numbers since B2B customers are required to self-assess the GST on their end.
How do I enter my GST number?
B2B customers can enter their 9-10 character GST number in the “GST Number” in the Account Details Page
You can validate your GST, NRIC, or UEN number at the Singapore GST Registered Business Search
How is GST determined?
GST is applicable based on the type of products or services that are purchased. We have determined that all of Twilio Sendgrid’s services are subject to GST.
Please ensure your service address is up to date in the Account Details Page for correct taxation.
What rate is GST charged in Singapore?
Twilio SendGrid's services will be subject to the 9% GST rate as determined by the Inland Revenue Authority of Singapore (IRAS)
For example, a customer in November 2025 would be charged the GST standard rate of 9% for all taxable sales. If this customer spends $1,000 with Twilio Sendgrid out of which $1,000 is taxable, they would be charged an additional $90 for GST, for a total of $1,090
Total taxable sales: $1,000
Goods and Services Tax (GST) @ 9%: $90
= Total including taxes: $1,090
I forgot to enter my GST number, but am a GST registered B2B customer - can I request a refund?
If you are a B2B customer with a valid GST number in Singapore, please contact our Support team for a credit of the GST amount charged within 90 days of the initial charge. For invoices issued in closed periods, we will credit the VAT charged in the following month’s invoice.
Where can I see the GST charged on my Invoice?
You can see the GST amount charged in the Tax Summary section of your invoice. Your invoice will continue to show subscription charges, usage and taxes in the same currency as before.
