An e-invoice generated 2 months after the invoice date:
• An invoice dated 4 August 2023 with IRN generated on 14 October 2023: for AATO below Rs 100 crore in 2023, the 30-day limit didn't apply, so the IRP accepted it. The IRN date differs from the invoice date, but GSTR-1 uses the invoice date (August 2023).
• The invoice auto-populates in the GSTR-1 of the period when the IRN was generated (October). Report it with the original date as a missed invoice (August). If tax wasn't paid in August, pay with interest from the August due date.
• For AATO of Rs 10 crore or more (from April 2025), such late reporting is blocked by the 30-day rule.
