RBI direct G sec securities

You are right Maheshji..In a scenario explained by you of GSEC being purchased from RBI direct retail and repaid on maturity, no capital gain will be applicable.  Simply any interest paid in between will be taxable. 

@ Ravish ji ...thanks for reply.

Sir, My point is if I buy from  RBI trading platform ( not directly first issued by rbi) and amounts directly credited to my account on MATURITY , then in this scenario, will it be LTCG/STCG??

Above query is different from scenario where I get allotment on 1 St instance directly from auction by RBI and account credited on maturity ( here only int is taxable.....no qs of LTCG/STCG) as i am buying on 1 St auction and on maturity directly credited in a/c
