The problem

Manual Excel reconciliation between GSTR-2B and purchase registers takes hours for even a mid-sized business. Mismatches in invoice numbers, GSTIN formatting, and date discrepancies go undetected until a notice arrives. Meanwhile, ITC eligibility keeps evolving — auto-restriction under Sec. 16(2)(aa) (ITC only for invoices appearing in GSTR-2B), the 180-day payment condition in the second proviso to Sec. 16(2), and the retrospective CGST (Amendment) Act 2024 that overrode Safari Retreats for Sec. 17(5)(d) construction ITC — all require constant vigilance.

Ask TaxMarg

A real question, a cited answer

app.taxmarg.ai · sample answergrounded
Our India-based SaaS company invoices a US customer for subscription access. Does this qualify as an export of service under IGST Sec. 2(6), and can we opt for LUT to avoid paying IGST upfront?
Based on TaxMarg's knowledge and sources3.8s · 4 sources
Yes. A SaaS subscription supplied to a US recipient is a supply of service, and qualifies as an export of services under Sec. 2(6) of the IGST Act, 2017 if all five conditions are met: (a) the supplier is located in India; (b) the recipient is located outside India; (c) the place of supply is outside India (default rule under Sec. 13(2) IGST Act for B2B online / cross-border services); (d) payment is received in convertible foreign exchange (or INR wherever permitted by RBI); and (e) the supplier and recipient are not merely establishments of a distinct person under Explanation 1 to Sec. 8. [Sec. 2(6)] Export of services is a zero-rated supply under Sec. 16(1)(a) of the IGST Act. [Sec. 16(1)(a) & Sec. 16(3)] You have two options under Sec. 16(3): (i) supply under an LUT (Letter of Undertaking filed in Form GST RFD-11) without payment of IGST and claim refund of unutilised input tax credit; or (ii) pay IGST on the supply and claim refund of the IGST paid. Most SaaS exporters prefer route (i) to avoid the working-capital hit. [Rule 96A + Form GST RFD-11] Remember the 30-day BRC requirement — foreign exchange must be realised within the period allowed under FEMA (default 9 months for software exports, extendable).
