The Rajya Sabha Select Committee, which adopted the report after scrutiny of the Constitution Amendment Bill, is likely to submit the report to the Upper House later in the week.
Besides Congress, sources said, left parties too are likely to file dissent note on the report.
The Congress, they said, in the dissent note has objected to the proposed composition of the GST Council, imposition of 1 per cent additional manufacturing tax by states and demanded safeguarding of revenue of panchayats and municipal bodies.
The dissent note, sources said, stresses that the current bill is full of compromises, exclusions and exceptions.
Congress is also demanding a ceiling of 18 per cent GST rate to avoid any burden on consumers, especially the poor.
It is also for compensation to states for revenue loss for five years, a demand which has been accepted by the government, sources added.
The opposition party is also seeking that the states representation in the GST Council, which will overseas implementation of the law, should be increased to three-fourth from the proposed two-third.
The government aims to roll out the GST, a new indirect tax regime, from April 1, 2016.
