Few sale invoices missed while filing gstr3b for march 2019

As per CBEC Circular 26/26/17 dt 29th dec 2017 clarification has been issued on rectification of various errors in gst returns in a tabular format. In case you have filed GSTR 3B for a month with error, you have to rectify it in the next month GSTR 3B. If you are yet to file GSTR 1 for jan 19 to march 19, you should include it in the GSTR 1 itself.

Thanks for the reply. So will i have to pay tax amount with interest in April Gstr3b ?

You should pay the tax amount along with interest in April GSTR 3B
