Is E-Invoice Compulsory for Your Business?
GSTZone Desk · Updated 2026
Short answer
Yes, if your aggregate turnover has crossed ₹5 crore in ANY financial year since GST began (2017-18 onward) — the current notified threshold. And once it applies, it keeps applying going forward even if your turnover later drops below that figure.
In detail
The e-invoicing threshold has been progressively lowered several times since it was first introduced, moving from an initial ₹500 crore requirement down through ₹100 crore, ₹50 crore, ₹20 crore, ₹10 crore, and now ₹5 crore (effective from 1 August 2023 per the applicable notification).
The test looks backward at ANY preceding financial year, not just your current one. A business that had a single high-turnover year some time ago, then scaled down, is still within scope — the obligation, once triggered, doesn’t switch off just because turnover later falls below the threshold.
E-invoicing applies specifically to B2B supplies and exports — invoices to unregistered consumers (B2C) are generally outside its scope, even for a business that’s otherwise required to e-invoice its B2B transactions.
GSTZone tip
Check your turnover figure across every financial year since GST began, not just your most recent one, before concluding e-invoicing doesn’t apply to you — a lot of businesses miss this because they only look at the current year’s number.

What if I’m a new business that just crossed ₹5 crore this year?+
The requirement applies from the date you cross the threshold in the notified manner — check the specific effective-date rules, since there’s usually a short transition period after first becoming liable.
Does e-invoicing apply to exempt supplies?+
No — e-invoicing is meant for taxable B2B supplies and exports; purely exempt supplies generally don’t need to go through the e-invoice registration process.
