We have exported some goods in January 2020 which were purchased in November 2019. The ITC claimed in GSTR-3B is very less. We have already claimed refund for December 2019 for exports done in December 2019. Now how can we claim due ITC refund for January 2020 exports as GST-3b for January has very less ITC claimed. I want to know can we claim more refund than ITC claimed in GSTR-b for particular month.
