Hi Ravi,
It is better for you to revise your last year's return rather than booking in this year. Further, question to ask whether any income generated on such investments and if yes whether such income has been shown for tax purpose in last year itself?
If income generated therefrom in last year also and you are not showing such income from that investment made, then it is highly advisable to revise ur return. Otherwise UR assessing officer may levy penalty under section 271(1)(c) of the income tax act for concealment of income gerenated from such investment.
Hope This solves ur query.
Thanks and Regards,
Manoj B. Gavali
