Online trading via eBay: VAT / GST / CST?

to import the goods, u need PAN /IE Code/ VAT

to sale the goods u need PAN/VAT/CST ( mandatory if turnover exceeds 5 lacs otherwise optional)

but its preferred to have vat registered to claim back the Special Additional Duty paid at the time of import. 

Hi,

You are required to get VAT registration even if you are doing trading online. Once you sell taxable goods in any state, you need to get registration and collect and pay vat to the state(subject to certain conditions).
