As per Note given by Ministery of Finance to Standing Committee on Finance and presented on 9-3-2012 in 49th report of Committee:
The Income-tax
Act, 1961, has
been subjected to numerous amendments since
its passage fifty years ago. It has been considerably revised, not less
than thirty-four times, by amendment Acts besides the amendments
carried out through the annual Finance Acts. These amendments were
necessitated by policy changes due to the changing economic environment, increasing sophistication of commerce, increase in international transactions
as a result
of globalization, development
of information technology, attempts to minimize tax avoidance and in order
to clarify the statute in relation to judicial decisions. As a result of all these amendments, the basic structure of the Income-tax Act has been
over burdened
and its language
has become complex. In
particular, the numerous amendments have rendered the Act difficult to decipher by the
average tax-payer. The Wealth-tax
Act,
1957 has
also witnessed amendments.
