Tax intelligence

Plain-language guides on capital gains, loss harvesting, F&O filing, and everything you should know before March 31st — written by a trader who built the tool because he kept finding out in April.

How to minimise tax on stock market gains in India — a complete guide

What is tax loss harvesting and how does it work in India — with no wash-sale rule

Does trading F&O mean I have to file ITR-3? Yes. Here's what happens if you don't.
If you traded futures or options at any point during the financial year — even once, even a small position, even if you lost money — you cannot file ITR-2. Here's exactly why, and what getting it wrong costs you.

Know your tax position before your CA does.
