Dear Sir
Thank you for immediate reply to our Query.
1. We have exported goods with payment of IGST and same is credited by Custom after filing GSTR-1 and GSTR-3B as per amount mentioned in GSTR-1 under Export with Payment of IGST details.
2. Second query, I wished to address with following example.
During march 2025 Total sales was Rs 10,00,00,000/- out of which Domestic Sales @ 5% is Rs. 3,00,00,000/- and Export Sales with Payment of IGST @ 5% Rs, 7,00,00,000/-.
Raw Material purchased is @ 18% Tax Rate.
My Question is while applying for Inverted Duty Structure (IDS) refund, in Tunover for Inverted duty refund i.e. lower output sales whether both (Domestic Sales Rs. 3,00,00,000/- and Export Sales with Payment of IGST Rs. 7,00,00,000/- will included or not.
