Kindly allow me elaborate my earlier views by explaining GST implications in slightly different situation.
Instead of export, let's take same situation for a domestic supply where tax-payer / supplier had raised a tax-invoice charging applicable GST while removing subject goods from his place of business, vehicle carrying those goods got stolen & goods were never recovered, sale remained incomplete & intended buyer never paid anything to the supplier and there was no insurance taken by the supplier. Question is what are GST implications in this situation. And my views are as follows:
A. As supply & taxable event is already taken place as per GST Law/s, and hence, supplier is bound to pay applicable taxes.
B. There is no provision under GST laws which allows such supplier to claim refund against such taxes so paid.
C. Credit-note u/s 34(1) of the CGST Act, 2017 cannot be issued by the supplier as above scenario is NOT captured in section 34(1).
D. And as those goods are already supplied, there is no question of any ITC reversal u/s 17(5)(h). Para 2(A)(ii) of the Circular no 92/11/2019 F NO 20/16/04/2018 GST date 7/3/2019 is worth noting in this regard.
E. Accounting treatment (as per applicable accounting standards) given in books of accounts does not change above position of GST implications.
Now, coming back to original situation raised by the querist (i.e. where goods were exported) read with my earlier post/s:
Just because Dept. cannot recover any taxes there-against as outward supply (as same was zero-rated supply as per Section 16(1) of the IGST Act, 2017), ITC reversal cannot be forced on the tax-payer using Section 17(5)(h) as those goods were already supplied as per GST law/s. This is NOT 'either / or' situation (i.e. same goods cannot be 'stolen' as well as 'supplied' under same law).
And difference/s between 'GST laws & its implications', 'accounting methodology as per applicable standards' and 'RBI / FEMA regulations' etc. can be properly explained & legally defended (i.e. as, if and when so required)
Of-course, as always the case for every controversial / litigation-prone issue, it is for every tax-payer who has to take these calls 'individually / for himself' depending upon so-many different factors (such as risk-appetite, quantum involved, willingness to go through judicial process/es & costs thereof, professional calibre and past record of his consultant handing complicated cases & so on).
