The govt on Tuesday introduced a Constitution Amendment Bill in the Lok Sabha to facilitate implementation of the Goods and Service Tax (GST), an indirect tax regime that would subsume levies like excise, service tax and sales tax.

The Bill, introduced by Finance Minister Pranab Mukherjee seeks to amend the constitution with a view to confer simultaneous powers on centre and states to levy taxes on goods and services.

"The GST would replace a number of indirect taxes presently being levied by the central government and the state governments and is intended to remove cascading of taxes and provide a common national market for goods and services", said the statement of objects and reasons of the Bill.

The Bill provides for creation of a GST Council to be headed by Union Finance Minister.

The Council will be empowered to recommend tax rates and exemption and threshold limits for good and services.

Besides, the bill proposed a GST Dispute Settlement Authority to deal with grievances of the centre and the state with regard to GST.

The GST, which is considered to be a major tax reform, has been pending for the last four years due to differences between centre and some states over the structure of the new tax regime.

"The decision to table the bill is a positive development. The Finance Minister was committed to bring it in the current session and he is doing that," Ernst and Young Tax Partner Harishanker Subramaniam said.

The Finance Ministry has worked on the final draft Constitution Amendment Bill, the fourth since the discussions on the new tax regime commenced.

Earlier, the first three drafts prepared by the Centre were rejected by the states citing autonomy issues.

The fourth draft, a hybrid of the second and third draft, has proposed setting up of a modified GST council through a presidential order for taking decisions on all important matters.

In addition, the composition of the GST Dispute Resolution Authority, proposed to be a part of the Constitution Amendment, will be decided by Parliament.

Furthermore, petroleum, natural gas, diesel and ATF have been kept out of the GST ambit in the final draft.

Last year, a draft Constitution Bill proposed by the Centre to the states had suggested a council chaired by the Union Finance Minister, with states as members, to make changes in GST.

The states, especially NDA-ruled ones, had raised objections to the proposal, saying it would give veto power to the Union Finance Minister over state taxation issues.

The Centre subsequently provided another draft to states, suggesting that changes in GST could be made only if there was a consensus on those issues in the council.

However, some state finance ministers did not agree to even this suggestion.

Taking into consideration the states' concerns, the Finance Ministry had then floated a third draft on the GST Constitution Amendment Bill.
