Dear
My considered opinion is like this:
The issuance of a Bank Guarantee by the Dubai-based Bank constitutes an import of financial service under the provisions of the IGST Act, 2017. The service provider is located outside India, while the recipient is situated in India, and the place of supply, as determined under Section 13(2) of the IGST Act, is the location of the recipient. Accordingly, all three conditions under Section 2(11) stand fulfilled.
The transaction, therefore, qualifies as an import of service, and the Indian recipient is duly liable to discharge IGST under the Reverse Charge Mechanism (RCM) in terms of Section 5(3) of the IGST Act read with Notification No. 10/2017-IGST (Rate).
The supply of service does not terminate in Dubai, as the benefit and consumption of the guarantee service occur in India.
I appreciate your analysis.
