Income tax for the sales in amazon, flipkart etc.
I am planning to sell items in amazon. These items are collected from villages and hoseholds where there is no proof for purchase.
I am aware there is GST involved. But what about the income tax. Apart from GST, do I have to include the money from sales while considering my income for ITR filing.?
1. Should I consider sales or profit?
2. As there is no proof of purchase, ow can I submit evidence for the profit?
3. Which ITR, if I have other salary as well?
Thanks in advance
