GST Return

By September 2019 you will have to file return gstr-3b and gstr-1

You have to file GSTR 3B by 20th Aug for the month of July 19 and if you have selected quaterly return filing then file GSTR 1 in the month of Oct 19 and if monthly then 11th of next month for the month for which return has to be filed
e.g. for july 11th Aug

I hv wrongly filed Gstr1 of any client ...I had to file gsr1 quarterly but I have fill sale invoices of only one month. so how can I improve this mistake in next return

For the month of July 2019 : GSTR-3B needs to be filed within 20th August 2019 inorder to avoid late fees of Rs. 25/50 per day.

And if you have opted for Quarterly filing of GSTR-1 ( Statement of Outward Supply commonly known as Sales ) , then for the Q2 you are required to file within 31.10.2019. Whereas, if you have opted for monthly GSTR-1 , then the due date to file GSTR-1 is 11th of the following month ( i.e 11th August 2019 for July month )

NOTE : GSTR-3B and GSTR-1 will be replaced by NEW RETURNS FORMAT. GSTR-3B will be replaced by FORM GST RET-01 and GSTR-1 will be replaced by FORM GST ANX-01. From January 2020 onwards, all taxpayer ( Small as well as Large ) will be filing GST RET-01 and GSTR-3B will be completely phased out.

Warm Regards.

Sir, GSTR-1 for the month of July-19 to be filed as per previous format only?

Yes Ma'am...
