Export Invoice Under LUT: Format, Declaration and Currency

Last reviewed

Quick answer

Exports are zero-rated under section 16 of the IGST Act. If you have filed a Letter of Undertaking (LUT, Form GST RFD-11) for the financial year, you can export without paying IGST. The invoice must carry the endorsement “Supply meant for export under Letter of Undertaking without payment of integrated tax”, and show the recipient's name and address, the delivery address and the country of destination. You may invoice in a foreign currency such as USD or EUR.

When is a service an “export of services”?

Under section 2(6) of the IGST Act, the supplier must be in India, the recipient outside India, the place of supply outside India, payment received in convertible foreign exchange (or in Indian rupees where RBI permits), and the two must not be merely establishments of the same person.
