If you think you can cheat India Government by not using cc, you are fool. Incometaxindia knows everything you do by your pp or ap account. If you only transfer money between ap accounts or pp accounts its useless until you receive your money in Indian bank to see some real cash. If incometax wants all Indians financial information from any payment processor, they can do that and all payment processors have to obey their rules and guideline. If you belief that you are earning over the tax slap you just have to file incometax return, show your money as misslenious earning. If they get proper income tax, they will not bother you to know how you earn this money.
IF THEY WANT YOU CANT HIDE ANYTHING. THEY KNOW ALL YOUR EARNINGS. THEY WILL CATCH YOU, IF YOU DON'T PAY THE TAX.
