As an individual taxpayer, I would not pay to use ClearTax. I have filed returns both on the Indian Government website and ClearTax. I do not see an added advantage with ClearTax, they show the same bunch of fields and as a last step, submit the data to the government website (I am not sure if the Government website crashes, how this will help ClearTax). I assume the only advantage is they can read your Name, addresses and gross salary data from the two page PDF you upload, not a big deal IMO. As someone who has freelanced a bit, I would still not purchase their INR 5000+ plans. I have had CAs do it for 2500 or less. I assume the site is popular among first-timers or people who have not really tried the Income Tax website recently.
