GST Implication on Interunit Sales

I suggest take registration for each plant as different business verticals.

Then, though, supply will attract GST, the recipient will get ITC.

If you do not get registered then it will be a case of raising invoice on self.

Dear MC,

for your case, you have to raise/use STOCK TRANSFER under GST. there is no need to charge GST, because you obtain a single registration.

if we have two plant in same state and using same registration number and raising invoice on each other. what will be the gst invoicing procidure 
 

You need two different registration numbers to raise B2B invoice.

In case you don't want to take different registration in same state then do not raise invoice.

Send item as stock transfer as told earlier by Respected Satya Ji.
