What is an LUT (Letter of Undertaking) in GST?
An LUT is a legal document that a registered taxpayer submits to the GST department. By filing an LUT, you declare and undertake that you will fulfill all the export requirements and receive your payments in freely convertible foreign currency (or INR where permitted) within the timelines prescribed by FEMA regulations.Filing an LUT ensures that you can invoice your international clients with 0% GST instead of paying Integrated GST (IGST) upfront and then running after the government for a tax refund.
Eligibility: Who Needs to File an LUT?
You need to file an LUT if you satisfy the following conditions:
.You provide services to clients located outside India.
.Your place of supply is outside India, and you receive the payment in foreign currency (supported by a FIRC or BRC from your bank).
