An individual has invested whole of the proceeds received on sale of capital asset in construction of another capital asset in the same financial year.

Sec 54f being an Exemption of Income but NOT a Deduction of Income, please suggest whether filing of Income tax return before due date is mandatory for claiming exemption under sec 54? Is it enough if we file the return of Income only when the assessing officer serves a notice in future?
