My CA had said that he had filed GSTR 3B for the month of December.

But i manually checked the Portal and it says that GST 3b has been submitted (ie not filed).

ques) Whether there will be default and late fees or penalty will be leviable in case CA did not File it (till due date which is 20th jan)???

Thank You!
