Carry forward of EXCISE DUTY paid.

if you have invoice on which excise duty is shown separately than you will get full credit, provided goods are not older than 12 month as on 1st July (means invoice date is not older than 12 months)....
if you don't have excise invoice than you will get only 20% of the value of goods, if gst rate is 12 or less and 30% if gst rate is 18% or higher. this credit will be allowed only when you sold these goods and you have reduced the price to customer by the amount of benefit you are getting from the credit....the above mentioned percentage is on the amount of igst......in case cgst and sgst is charged, credit will be 40 and 60 percent respectively of the amount of cgst.....
