When did the 30-day rule begin?

The IRP states it took effect from 1 April 2025 for taxpayers with AATO of ₹10 crore and above.

Does every GST-registered business need e-invoicing?

No. Applicability depends on threshold, taxpayer type and exemptions.

Is a self-created QR code enough?

No. It is not a substitute for the required IRN/e-invoice process.

Check GSTIN enablement

The IRP guidance says the GST system identifies eligible GSTINs and taxpayers should check e-invoice enablement status; exemptions can apply.

Watch the 30-day restriction

For taxpayers with aggregate annual turnover of ₹10 crore and above, the IRP introduced a 30-day reporting restriction from 1 April 2025 for invoices, credit notes and debit notes.

Validate data before submission

Check GSTINs, document type and number, date, taxable value, tax amounts, HSN/SAC and supply details. Current API and validation changes should be tested against the live specification.

A PDF is not automatically an e-invoice

A professional PDF is still a document. An e-invoice is generated through the notified IRP process and associated with the IRN/QR data returned by that process.

Use the generator for preparation

FinTaxLife’s Invoice Generator helps prepare a clean invoice document; IRN generation and government registration still happen through the required e-invoicing workflow.
