You can get the circle rate for your land from sub registrar.
If the difference between circle rate and your sale price is more than 5% and if circle rate is higher it will be considered as your sale for capital gain.
What else do you want to know.
If you need any detailed discussion you can have a phone consultation.
Hope you find the information helpful if you do please rate it 5 and provide your valuable feedback for my improvement.
Thank you
