Do I need to pay Income Tax if i am running a escrow service in India
This may be closed as not quite PF, but really "startup" as it's a business question.  In general, you should talk to a professional if you have this type of question, specifics like this regarding your tax code. I would expect that as a business, you will use a proper paper trail to show that money, say 1000 units of currency, came in and 900 went out. This is a service, no goods involved. The transaction nets you 100, and you track all of this. In the end you have the gross profit, and then business expenses. The gross amount, 1000, should not be the amount taxed, only the final profit.
