Why the B2C and HSN B2C totals not matching in the GSTR-1 report?

The totals in the B2CS and HSN B2C sections of GSTR-1 may not match because:

  • B2CS includes the amounts of all invoices with products, regardless of whether those products have HSN codes.
  • HSN B2C shows totals only for products that have valid HSN codes.

So, if some of your products don’t have valid HSN codes, they’ll appear in B2CS but not in HSN B2C, leading to a difference in totals.
