Do you have to e-invoice? — GST e-invoice applicability checker

Enter your aggregate annual turnover and whether you raise B2B invoices. See if GST e-invoicing is mandatory for you, and if the 30-day reporting rule applies.

Free · no sign-up · a first check, not advice for your return: confirm it with your CA.

₹ crore

Example: ₹12 crore turnover, B2B invoices

Mandated — and the 30-day reporting rule applies

With AATO ≥ ₹10 crore, every B2B invoice/CN/DN must get an IRN from the IRP, and it must be reported within 30 days of the document date (in force from 1 Apr 2025, continuing FY 2026-27). Miss the window and the document cannot be reported at all.

Thresholds as of 30 October 2026: mandate > ₹5 cr AATO; 30-day reporting ≥ ₹10 cr (from 1 Apr 2025). Confirm the current CBIC/GSTN notification for your period — these have only moved downward.

From when it applied to you

Your peak turnover and the year you first crossed the line give the date the mandate started for your PAN.

₹ crore

Example: ₹7 crore, first crossed in 2023-24

Liable since 1 Apr 2024 — ~31 months of non-compliance

Every B2B invoice issued without an IRN since 1 Apr 2024 is not a valid tax invoice under Rule 48(5), your buyers' input tax credit on those invoices is contestable, and Section 122 penalties apply per document. Work out the exposure with the calculator in the deadlines guide, then talk to your CA this week, not this quarter.

Governing notification: 10/2023 – Central Tax. Assumes turnover stayed above the tier once crossed; trajectory edge cases exist, so confirm your exact start date with your CA.

How the answer is worked out

What this checker answers

Whether GST e-invoicing applies to you, from when, and whether the 30-day reporting rule binds you.

The rules come from GST notifications, which move the threshold by date, so every line carries the date it was checked. Read the answer as a first check, then confirm it with your CA for your own period.

What it rests on

  1. The turnover threshold and its historyCBIC notifications under Rule 48(4) of the CGST Rules, with notification numbers in the guide.
  2. The 30-day reporting windowGSTN's advisory on the time limit for reporting invoices to the IRP.
  3. Who is outside the mandateThe exemptions under Rule 48(4), in the deadlines guide's explorer.

What this cannot tell you

Four things to check before you rely on the answer, and who made it.

  1. Whether your entity is exemptBanks, insurers, NBFCs, GTAs, SEZ units and some others are outside the mandate. The guide's exemption explorer checks your category.
  2. The turnover the portal computedThe checker takes the figure you type. The GST portal shows the aggregate turnover it computed for your PAN; use that.
  3. A notification after our checkThe threshold moves by notification. Every rule here was checked on the date below; confirm the current one for your period.
  4. Your returnThis is a first check, not advice. When it decides money, ask your CA.
