New Delhi, Jan 2 (PTI) The government today ruled out having a single rate for all commodities under the Goods and Services Tax (GST) saying items like food products have been placed at minimum taxation levels while luxury goods were in the higher categories.

During the Question Hour in Rajya Sabha, Finance Minister Arun Jaitley said there were countries which had applied a uniform tax rate on all commodities but these were nations where the entire population was above the poverty line.

In India, food items have been placed in zero or the minimum slab while luxury items get taxed more, he said.

While the question of a single slab in India does not arise, the process of rationalisation would continue, he said.

Many items which were earlier in the 28 per cent bracket were brought into the 18 per cent bracket and this process of rationalisation would continue, the minister said.

He also said the GST council had formed a committee under the convenorship A B Pandey, chairman GSTN, to look into issues relating to the filing of returns and suggest a simpler mechanism to mitigate the compliance requirements for tax payers.

"The committee shall recommend changes to be made in the process of filing of returns in GST, including the threshold, if any, for quarterly filing," he said.

The report of the committee will be placed before the GST council for making recommendations on this issue, Jaitley said.

GST rate structure affirms differentiated taxation with essentials at minimum and luxuries higher; reform of returns filing planned. Differentiated GST taxation is maintained with essentials given the lowest tax treatment and luxuries higher; the government continues a process of rate rationalisation to move items into lower brackets. A committee will examine returns filing procedures and recommend simplified compliance mechanisms, including possible thresholds and filing frequency, with its report to inform further policy recommendations.
