VAT India and US
This is a great question and we have documentation that goes over this, which I'll link to you here:
More specifically to your question, we are collecting India’s Goods and Services Tax (GST) - and this would apply even if your Linode services are hosted outside of India. The "how much" depends on the cost of your services.
If you have a valid GST/Tax ID number and you provide it to us (details of how to do that are in the guide linked above), you would not be billed the GST.
