First time filing taxes, where do I start and what documents do I need to have ready?

I created a thread yesterday asking if I should file ITR if my income did not exceed the taxable threshold. I was advised to do so and I have decided to follow it and submit my ITR this time.But since this is my first time I have no clue where to start and need you help with it. Is it possible to do it myself (cleartax online) or will I need to consult with a CA? If I do it through a CA how much is it going to cost?I have 3 bank accounts, 2 Fixed deposits, 1 LIC policy and 1 ICICI health insurance.What documents do I need to have ready?Any other advice is very welcome.Thanks! via /r/IndiaTax https://ift.tt/36Ttx8M
