New Delhi: The Union Cabinet on Wednesday recommended an ordinance to ease tax rules for foreign investors in certain categories of securities.Details of the proposal tabled by the Finance Ministry were not immediately available. However, it is being seen as an effort to help strengthen the rupee, which has weakened 6% against the US dollar as foreign portfolio investors pulled out a record Rs 2.6 lakh crore from equities since January.The move is likely part of coordinated action with the Reserve Bank of India, which is likely to announce measures on Friday after its monetary policy committee meeting began on Wednesday.Through measures such as government-guaranteed credit lines for businesses and a package for exporters, in addition to adjustments in duties including on fuel, the government is trying to address concerns of various sectors to protect the economy from the impact of the West Asia war.But the fall of rupee and continuous withdrawal of FPIs from the market has been a matter of concern.Ahead of the Union Budget, representatives of FPIs had demanded tax changes, including a review of the capital gains tax regime for listed securities, and argued against the imposition of capital gains tax and securities transaction tax. Tax experts have said that over the years the government has increased long-term and short-term capital gains tax while imposing STT, making investment in India less attractive.
