For Indian exporters of goods, software developers, cross-border SaaS companies, and international service freelancers, managing liquidity is critical. Under Section 16 of the Integrated Goods and Services Tax (IGST) Act, exports of goods and services are classified as 'Zero-Rated Supplies'. Exporters have two statutory routes: pay IGST upfront at invoice generation and claim a refund later, or execute a Letter of Undertaking (LUT) in Form GST RFD-11 to export without paying any IGST upfront, preserving 100% of their working capital.
Statutory Framework & Key Operational Rules
Filing an LUT online is available to all registered taxpayers who intend to export goods or services or supply to Special Economic Zone (SEZ) developers/units, provided they have not been prosecuted for any offence involving tax evasion exceeding ₹250 Lakhs under the CGST Act. The LUT must be furnished online on the GST Common Portal before commencing export shipments or raising cross-border invoices for the relevant Financial Year. An LUT is valid for one entire Financial Year (April 1 to March 31) and must be renewed annually.
Maintaining accurate books of accounts and reconciling statutory ledgers (GSTR-2B, Form 26AS, AIS/TIS) prior to filing prevents automated scrutiny notices, penal interest under Section 50/234, and disallowed business expenditures.
Procedural Compliance & Professional Advisory
While exporting under an LUT eliminates output tax payment, exporters remain fully entitled to accumulate Input Tax Credit (ITC) on domestic procurement of business assets, software subscriptions, office rent, and raw materials. This accumulated unutilized ITC can be refunded directly into the exporter's bank account by filing Form GST RFD-01 under Rule 89(4). Furthermore, export of services requires realization of convertible foreign exchange within 1 year as per FEMA and RBI regulations to maintain zero-rated status. Expert tax advisors streamline LUT submissions and secure rapid ITC export refunds.
