Drop ship ecommerce business tax system

Hello Friends,

I am planning to start a drop ship ecommerce business, i need help to understand process for registration and tax filing system.

Here are the details:

I will be operating business from my home. It requires Laptop and Internet connection only. No office is required.

As per my business model i will be doing business in US market. people from USA will place order in USD and orders will be shipped from china. I am not buying or selling anything in India.

Here are my questions:

1) When i do GST registration to get GSTIN number, can i select  constituion of business as Sole Properitor ?

2) Since i am not buying any product from India and not selling to indian costemer ? do i still need to pay GST ? if yes what would be GST filing frequency ?

3) whatever i earn throughtout the year how i am going to pay taxes on that ?

Thanks in advance.

Regards,

Sunita
