How to Issue an Export Invoice under GST with LUT
GST Expert Team
Updated 9 April 2026
Is GST applicable on Exports?
Under GST law, export of goods and services is considered a "zero-rated supply." This means you don't have to pay tax on the final output, and you can also claim Input Tax Credit on your expenses.
Option 1: Export under LUT (Letter of Undertaking)
Most service exporters (Freelancers, Agencies) choose this option. You file a simple LUT form on the GST Portal at the start of every financial year.
- No IGST is charged on the invoice.
- The invoice must mention: "Supply Meant For Export Under Bond Or Letter Of Undertaking Without Payment Of Integrated Tax."
Option 2: Export with Payment of IGST
You charge IGST on the invoice and later claim a refund from the government. This is less common for service providers as it blocks working capital.
Mandatory Invoice Fields for Export
- Recipient's full international address.
- Currency of transaction (e.g., USD, EUR).
- Foreign Inward Remittance Certificate (FIRC) details (post-payment).
