Cancelling in Tally doesn't cancel the IRN:
• An IRN can be cancelled only on the IRP (directly, or through your software's API) within 24 hours of generation. Deleting or cancelling in Tally Prime after that window doesn't cancel the IRN. The invoice auto-populates in GSTR-1.
• If more than 24 hours have passed: you can't cancel. Issue a credit note (also via IRP) for the full value. Or, if the invoice wasn't actually supplied, delete or amend it in GSTR-1 before filing (Table 4 auto-populated invoices can be deleted in GSTR-1 if not yet filed, and that's allowed since IRP data is only a draft source).
• If GSTR-1 hasn't been filed yet: delete the auto-populated record in the GSTR-1 draft. GST law allows not reporting a cancelled invoice. But the IRN remains valid on the IRP, so keep documentation of non-supply.
