The all-powerful GST Council today revised rates on 29 items and 53 categories of services, and decided to make the process of filing GST returns simpler to ease compliance burden for small businesses. The new GST rates will be applicable from January 25. Briefing reporters after the meeting, Finance Minister Arun Jaitley, who heads the panel, said the next meeting of the Council may consider bringing items like crude oil, natural gas, petrol, diesel, ATF and real estate within the GST purview. Nandan Nilekani, co-founder of Infosys, presented a detailed model on filing GST returns. The Council will be meeting again via video conferencing before the Union Budget to finalise on the new model presented by Nilekani.
