A high-profile row with foreign investors had erupted late last year following the retrospective imposition of the minimum alternative tax (MAT) on funds, including Aberdeen Asset Management .
With foreign investors holding a quarter of the shares on the main Sensex board, the controversy rattled Indian markets and there was relief after the government announced on Tuesday that it would waive those tax demands.
"The fact that government has acted on the recommendations so fast shows that they really don't want to rock the boat," U.R. Bhat Managing Director at Dalton Capital, a Mumbai-based fund that caters exclusively to foreign investors, said.
"What's clear is the government really wants to resolve its tax disputes with foreign investors."
The government's about-face comes at a time when equity markets around the world are suffering due to volatility in China. India has been no exception, with foreigners selling a record amount of Indian shares last month.
