 Linode collects the European Union's Value Added Tax (VAT) for customers that are subject to it. Starting on October 1st, 2019, Linode will also collect Australia and India's Goods and Services Tax (GST) for customers in those countries.
 
+Additionally, starting September 1st, 2020, Linode will collect Singapore's 7% Goods and Services Tax (GST) for customers in Singapore.

If your business is registered for GST but you do not add your GST ID to your account, your invoice for usage in September will include the 7% GST charge.
