LONG TERM CAPITAL GAIN AND TAX LIABILITY

Learned Members,

We had purchase some shares (physical) worth Rs 25000 in the year 1990

After getting dmated in year 2010, we had sold the shares, paid STT and earned Rs 200000 from the said shares...

We have not paid any tax at time of purchase or selling except STT.

We have received a notice from the IT department for the said year

Do we need to pay LTCG??
Are we supposed to pay any other taxes??

Thanks in advance.....
