After obtaining a valid GST Regn no of a Courier Agent during 17-18 , NIL return has been filed till Sept 2018 but later on i heard by someone that he died and i personally could not trace out his residential address for personal communication . And due to non-communication with his family members , i could not apply for his cancellation of gst no . Problem is that he died on july 2018 most probably but Gstr 3b FILED till Sept 2018 ( i.e, three months return has been filed after his deaths also , ok ).
1) After death of a businessman also , three months return ( GSTR 3B ) has been filed but when i came to know the truth that he was dead then i stop filling his return .
Should i face any problem for the above mistake or Not ? ( totally NIL RETURN )
2) If i could not trace out his address for communication with his family members , then how could i cancel his GST no ?
Regards
