We export services but forgot to renew the LUT for FY 2026-27 and have invoiced without IGST since April. What now?

The rule is that a Letter of Undertaking in Form RFD-11 should be furnished before exporting without payment of IGST, and it is valid for one financial year. Circular 37/11/2018-GST (paragraph 4) states that where an LUT is filed late, the delay may be condoned and the facility allowed on an ex post facto basis, provided the exporter was otherwise eligible. Eligibility is simple: you must not have been prosecuted for evasion above ₹2.5 crore. File the LUT on the portal today (it is accepted instantly without officer approval), keep the acknowledgement, and quote this circular if a notice ever arrives.

Two things to put in order: make sure each export invoice carries the words "supply meant for export under LUT without payment of IGST", the client's address outside India, and the place of supply; and reconcile the ₹70 lakh of receipts with FIRCs or bank advices showing convertible foreign exchange. Exports must be realised within nine months of the invoice under FEMA; unrealised invoices beyond that period lose zero-rating and attract tax with interest.

Also check that these invoices were reported in GSTR-1 table 6A as exports without payment of tax and in GSTR-3B table 3.1(b); if they went into the regular taxable line by mistake, amend in the next GSTR-1.
