If You are correctly filed Your GSTR 1 return then no need to worry about GSTR 1 return...
But Your GSTR 3B return is not correctly filed by You. Also GSTR 3B is based on transactions like inwards and Outwards. After set off we have the exact details of ITC / Payable tax liability in every month... If we missed some invoices then it will penalize at the time of Audit and annual return...
We are give just advice and based on current situation. Follow up only on Your end...
Sir thank q for advice and quick responce, my doubt is filing this month sales in next month gstr 3b may lead to double payment of tax as I had already shown previous month sales in gstr 1 of that month and for that I need to pay tax in gstr 3 which was yet file
Now payment is payable based on GSTR 3B return... GSTR 3 is available now..
In case GSTR 3 is available then it's based on Our all previous filings, payments and adjustment... it's not Perform individually itself... So, No way for double tax payments...
