We are a freelancer and providing export of services and accepting payment through Paypal. We are duly registered under GST since our receipt exceeding rs 20 lakh. In f.y. 2019-20, we made export of service amounting rs 1 crore. out of which paypal transffered rs 90 lakh to our bank account, and for remaining rs 10 lakh it has issued us a GST invoice charging IGST for its services. When we applied firc to citi bank, it has issued us firc of only rs 90 lakh. Now we have firc of rs 90 lakh and service bill of paypal rs 10 lakh including IGST. Now we want to claim refund of that IGST charged by paypal. Now my question is this that our export was of rs 1 crore and we have firc of rs 90 lakh only. So will it create any problem while issuing us the refund amount.
