Fitment in GST slabs: Announcement of details could go beyond May, says Hasmukh Adhia

So Delay in announcing Slab Rates under GST is intentional. They have declared general rates and shared few ideas like Zero Tax on Some Segments of Food Items, Education, Health, Transport & high tax on luxury items etc. But complete list would be treated as a budget item, to be declared on last moment. Govt afraid if announced in advance, the smart tax payer will have enough time to change category of items from high tax rate slab to low or nil tax rate slab. As in past some smart companies have been accused for the same practice. Changing category of goods/services. But It won't make any difference in processes, so keep working on your accounting or ERP customization. Thanks.
