A 4-tier GST tax structure of 5, 12, 18 and 28 per cent, with lower rates for essential items and the highest for luxury and de-merits goods that would also attract an additional cess, was decided by the all- powerful GST Council today.

With a view to keeping inflation under check, essential items including food, which presently constitute roughly half of the consumer inflation basket, will be taxed at zero rate.

The lowest rate of 5 per cent would be for common use items while there would be two standard rates of 12 and 18 per cent under the Goods and Services Tax (GST) regime targetted to be rolled out from April 1, 2017.
