Hi, this is a practical case im currently facing. A company had raised an intra state invoice to another company and had paid CGST and SGST for the month of august in GSTR 3B. However during october the company or the area was notified as SEZ. Now during January when im filing GSTR 1 for the month of august the portal is automatically considering the supply as inter state for the GSTIN i provided.
Is there anyway to avoid discharging differential tax amount with GSTR3B and GSTR1?
Thanks in advance.
