E-Invoicing Threshold Reduced to ₹5 Crore

E-invoicing (electronic invoicing) has been progressively expanded to cover more businesses. As of 2026, all businesses with annual aggregate turnover exceeding ₹5 crore in any preceding financial year must generate e-invoices for all B2B (Business-to-Business) transactions.

What is E-Invoicing? E-invoicing does not mean creating an invoice in electronic format — it means uploading the invoice to the Invoice Registration Portal (IRP) and receiving an IRN (Invoice Reference Number) and QR code before sharing with the buyer
Who Needs to Comply? B2B suppliers with aggregate turnover > ₹5 crore. Does NOT apply to: B2C (individual consumers), banking/financial services, insurance, SEZ units, government departments
Penalty for Non-Compliance E-invoice not generated = Invoice is invalid for ITC purposes. Buyer CANNOT claim ITC. Penalty: 100% of tax due or ₹10,000, whichever is higher per invoice
How to Generate Use any IRP-compliant accounting software (Tally, Busy, Zoho Books) or directly on einvoice1.gst.gov.in. Upload invoice JSON, receive IRN & QR code, embed in PDF invoice
Coming Soon: The government has indicated e-invoicing will be extended to businesses with turnover above ₹1 crore in the near future. Prepare your systems now.

New GSTR-1A Amendment Return

One of the most taxpayer-friendly changes in 2026 is the introduction of GSTR-1A — a new return that allows you to amend details in GSTR-1 after filing, but before GSTR-3B is submitted for the same period.

What Can Be Amended? Incorrect B2B invoice details (GSTIN, amount, tax rate), HSN summary errors, document summary mistakes, missing invoices that were accidentally omitted
When to File? GSTR-1A can be filed between the due date of GSTR-1 and the due date of GSTR-3B. Once GSTR-3B is filed, GSTR-1A cannot be filed for that period
Process Go to GST Portal → Returns → GSTR-1A. Select the tax period. Make corrections and submit. The amended data automatically updates GSTR-2B of your buyers
Limitations GSTR-1A cannot increase tax liability beyond what is declared in GSTR-1 for that period. For increasing outward tax liability, you must amend in the next month’s GSTR-1

Stricter ITC Rules 2026 — What Changed

Input Tax Credit (ITC) rules have been significantly tightened in 2026. The era of provisional ITC based on self-declaration is over. ITC is now strictly linked to GSTR-2B — the auto-populated statement of available ITC.

No Provisional ITC The 20% provisional ITC (allowing you to claim ITC even before supplier files GSTR-1) has been completely phased out. You can only claim ITC that appears in your GSTR-2B
GSTR-2B Reconciliation Before filing GSTR-3B, reconcile purchase register with GSTR-2B. Any ITC claimed in GSTR-3B that is NOT in GSTR-2B is at risk of reversal with 18% interest + penalty
Time Limit for ITC Claim ITC on invoices must be claimed by the earlier of: (a) November 30th of the following financial year, or (b) the date of filing annual return (GSTR-9). Missing this deadline = permanent ITC loss
Blocked ITC ITC remains blocked (Section 17(5)) on: personal expenses, motor vehicles (with exceptions), food & beverages, club memberships, works contract services for immovable property
Action Required: Ensure all your suppliers are filing GSTR-1 on time. Follow up with defaulting suppliers before month end. Use GSTR-2B monthly reconciliation as a standard process. TaxGyani’s team helps businesses with GST return filing and ITC reconciliation.

HSN Code Reporting Now Mandatory at 6-Digit Level

Turnover < ₹5 Crore 4-digit HSN code mandatory for B2B invoices. Optional for B2C invoices
Turnover > ₹5 Crore 6-digit HSN code mandatory for all invoices (B2B and B2C). This was extended in 2026 and strictly enforced through e-invoice validation
GSTR-1 HSN Summary HSN-wise summary in GSTR-1 is now auto-validated against the HSN codes in individual invoices. Mismatches are flagged and can block GSTR-1 filing
Wrong HSN Penalty Incorrect HSN classification can lead to demands for differential tax (if rate varies by HSN), penalty of ₹50,000 per return, and potential litigation

Frequently Asked Questions

What are the major GST changes in 2026?
+
Major GST changes in 2026 include: e-invoicing threshold reduced to ₹5 crore turnover, introduction of GSTR-1A amendment return, complete phase-out of provisional ITC (strict GSTR-2B based ITC), mandatory 6-digit HSN codes for businesses above ₹5 crore, and enhanced AI-based scrutiny of ITC mismatches between GSTR-1 and GSTR-3B.
What is GSTR-1A and when to file it?
+
GSTR-1A is a new amendment return that allows you to correct errors in GSTR-1 (outward supplies) after it is filed, but before GSTR-3B is submitted for that period. File it on the GST portal → Returns → GSTR-1A between the GSTR-1 due date and GSTR-3B due date. It automatically updates buyers’ GSTR-2B.
Can I claim ITC if my supplier has not filed GSTR-1?
+
No. From 2026, ITC can only be claimed if it appears in your GSTR-2B, which is auto-populated from your suppliers’ GSTR-1. If a supplier has not filed GSTR-1, the invoice will not appear in GSTR-2B and ITC cannot be claimed. This makes it essential to work with GST-compliant suppliers who file returns on time.
Is GST being reduced on insurance in 2026?
+
As of April 2026, the reduction of GST on health and term insurance is under active consideration by the GST Council. The current rate is 18%. A reduction to 12% or even NIL for pure term insurance has been proposed but not yet officially approved. Check taxgyani.com for the latest update when the decision is announced.
What happens if I claim wrong ITC under GST?
+
Wrong or excess ITC claims are treated as tax evasion under GST. The consequences are: 100% penalty on wrongly availed ITC + 18% annual interest from the date of ITC claim to reversal. Serious cases can attract Section 132 prosecution. Always reconcile GSTR-2B before claiming ITC and get CA support for complex ITC calculations.
