Shri Kasturiji Sir,
At very outset, refund of any tax paid (whether it is of zero rated (including export) or unutilized ITC) is governed by Section 54(1) of CGST Act. It is further bifurcated as for refund of unutilized ITC which will be governed by Section 54(3). The refund amount is required to be credit to welfare fund, but in terms of provision of Section 54(8) the refund amount is to be given in cash. For the tax paid for export of goods or service or both, is to be refunded in cash (refer Section 54(8)(a)).
In the given circumstances, it is important to peruse term “refund” which is given below for ready reference
“(1) “refund” includes refund of tax paid on zero-rated supplies of goods or services or both or on inputs or input services used in making such zero-rated supplies, or refund of tax on the supply of goods regarded as deemed exports, or refund of unutilised input tax credit as provided under sub-section (3).”
The services exported with payment of tax, will be governed by Section 54(1) for the purpose of limitation period of two years from relevant date. Considering that service has been exported and Invoice was also raised, but payment is not received. In this case, Explanation (2) (c) will not be applicable as for (i) receipt of payment in convertible foreign exchange or in Indian rupees wherever permitted by the Reserve Bank of India1, where the supply of services had been completed prior to the receipt of such payment, for (ii) is for advance payment.
In the present circumstance there is no receipt of payment, therefore, (c)(i) is also not applicable sub-section (h) is applicable and two years of time limit can also be invoked.
Moreover, the refund is for tax paid on export of service, one of the two interpretation can be made;-
(1) Service provided, Invoice issued and tax paid but no consideration is received is out of ambit of “Supply”, therefore, excess tax paid
(2) Service provided, Invoice issued and Tax paid, deemed to be supply and refund of tax paid.
Here, refund is of tax paid. Time of supply is relevant in the present case, as payment of tax is to be made, for purpose of filing of refund claim and to arrive at the relevant date (Refer Explanation given at Section 13, which determines the time of supply (erstwhile point of taxation) (also refer Section 7(5) of IGST Act)
These are my view.
With Regards
