Formula & How It Works

e-Invoice Mandatory if: Turnover > ₹5Cr AND Supply Type is B2B / Export AND Entity is not exempt (bank/ISD/GTA/SEZ)
Current threshold: ₹5 Crore (FY 2023-24 onwards)

Worked Example

Scenario: Turnover ₹8Cr, B2B supply, regular taxpayer → MANDATORY

Turnover ₹3Cr, B2B supply → NOT applicable (below ₹5Cr)

Turnover ₹8Cr, B2C supply → NOT applicable (B2C exempt)

When to Use This Calculator

  • Check if new clients need IRN on your invoices
  • Verify compliance before dispatching B2B goods
  • Onboard e-invoice generation before deadline
  • Train billing team on IRN requirements
  • Avoid ITC disputes by issuing valid e-invoices
