The General Anti-Avoidance Rules (GAAR), which will target companies and investors routing money through tax havens, had been scheduled to be implemented from April 2014. They will now come into effect from April 1, 2016.

Chidambaram said GAAR will not apply to foreign funds that are not taking any benefit from India's various tax treaties with other nations.

GAAR will also not apply to non-resident Indians running foreign funds, he told a news conference.

The minimum threshold to come under GAAR will be 30 million rupees, Chidambaram said.

India's moves to toughen tax collection last year had triggered an outcry from global industry groups and were blamed for a fall in investment flows into India.

In response, Prime Minister Manmohan Singh set up a panel to look at ways of addressing concerns that the new laws were arbitrary.
