Export goods and services without paying IGST upfront — the Letter of Undertaking that keeps your working capital out of the refund queue.
Starts at ₹1,499 + government fees, if any
A Letter of Undertaking (LUT, Form RFD-11) lets exporters supply goods and services — including services billed to foreign clients — at zero-rated GST without paying IGST first and claiming refunds later. It is valid for one financial year and must be refreshed every April; miss the renewal and your exports technically require IGST payment from day one of the new year.
Every freelancer, agency and SaaS company billing clients abroad should hold a current LUT — the alternative locks 18% of every invoice into the refund pipeline for months. FilingBase files it the same week, calendars the renewal, and checks that your invoices carry the required LUT declaration.
