The new tax structure is effective from April 1, 2019.

Finance Minister Nirmala Sitharaman announced a slew of measures on Friday to revive sagging investment in country's economy, including a cut in corporate taxes. Ms Sitharaman said that the effective corporate tax rate will be lowered to 25.2 per cent from 30 per cent, which she said would be at par with Asian peers. The new tax structure is effective from April 1, 2019. This change will be made through an ordinance to amend the Income Tax Act, 1961. The centre will have to bear a cost of Rs. 1.45 lakh crore this fiscal to support its decision to reduce corporate tax, Ms Sitharaman said.

Here's what tax experts say on the corporate tax rate cut:

"The corporate tax relief announced by the Government will definitely boost the economy and increase capital investments. Increase in capital investments will lead to more job opportunities and growth. Whilst it may take some time for the investments to materialise, it is a step in the right direction. One should also examine how this move impacts government spending."
