Rural Agricultural land in India is not considered a 'capital asset' as per sec 2(14) of the income tax act. As a result capital gain tax is not applicable on the same when it is sold.

TDS is also not applicable for the same reason and u/s 194IA which talks about TDS on sale of immovable property, sale of rural Agricultural land in India is excluded.

Inorder to get a certificate to show to the bank you can consult a practising CA in your area who will guide you in the matter.

what are the likely costs for this . 

Thanks
