The Union Cabinet on Wednesday approved changes suggested by a Rajya Sabha Select Committee to the Goods & Services Tax Constitution Amendment Bill, including compensating the States for five years for loss of revenue.
With this approval, the Government is all set to bring a revised Constitution Amendment Bill before the Rajya Sabha. The GST, to be rolled out from April 1, 2016, will replace all indirect taxes, including excise and sales tax, on all products, except alcohol. It has already been passed by the Lok Sabha but has been pending in the Upper House.
