How to make most from tax returns?

I am the owner of a small business on social media. My annual turnover is less than 15 lakhs. I wanted to ask: how do I get the most out of my tax returns? I was recently going through another site:  https://getsatisfaction.com/intuitindia that has helped me to some extent. They are offering their services for free. I would like to get some more info on the same. Thanks!!
