Dear Sir We have executed works contract in 2018-19 for a Govt Body, They deducted GST TDS in 2021-22, which we came to know Now ( i.e Nov-24) when EIU mismatch Notice came to us for mismatch of Turnover in TDS return filed by Deductor and Nil GSTR 1 Return filed by us in Nov-21, Till we not accepted the TDS credit. Based on these GST Dept is Demanding Tax and Interest for which we have already Paid Tax in 2018-19 and furnished details in GSTR 1. Just Because Deducter has Made payment and deducted tax and filed return after 3 Years , now what should be done
