GSTR Filing GSTR-1 & 3B on the same day

Due date for GSTR-1 filing will be 11th of subsequent month & 20th for GSTR-3B.

What will happen if we do both on 3rd or 4th ?

GSTR-1 is filed & GSTR-3B is also filed without generating the summary.But GSTR-1 details autopopulated

Quick Summary
This discussion explores the feasibility of filing GSTR-1 and GSTR-3B on the same day, specifically around the 3rd or 4th of the month. While technically possible to file both, members highlight a significant issue: Input Tax Credit (ITC) from GSTR-1 filings may not be fully reflected until the 14th of the month. Filing GSTR-3B before this date can lead to incomplete ITC, impacting the accuracy of your return. The consensus suggests filing GSTR-1 first and then waiting for the ITC to reflect before filing GSTR-3B to avoid practical problems.

You can't file gstr 3b before 14 th of the subsequent month.. because only by 14th the itc will get fully reflected from all gstr 1 filed by suppliers
ITC is not there for above case.
Better to do it after 14th as said by above member .

Do GSTR-1 filing first and then wait for summary to avoid practical issues
If ITC is not there then I can file GST returns on 3rd or 4th of subsequent months
