I am a proprietor of a supermarket.If I have a stock with old VAT rate 14.5% when Gst comes the rate of tax will be changed to 18%. I had already taken Input tax credit on 14.5% in vat. can I able to get any relief due to the change in rate of tax. how much tax I have to collect from customer. ? will I get any tax relief ? 18% of gst means sgst -9% + cgst 9% is these correct or not ?
