As the deadline of April 1, 2010, for introduction of proposed Goods and Services Tax draws closer, Prime Minister Manmohan Singh today asked the states to work towards expeditious implementation of the new indirect tax system.

"The states should work towards early implementation of the Goods and Services Tax," the Prime Minister said at the conference of state food processing ministers here.

He also asked the states to remove subjectivity in treatment and classification of food products.

The Centre and the states are yet to reach at an agreement for goods and services to be included in the GST regime. The decision on a lower levy on food products and exemption to some of them is also yet to be taken.
