Firm closed, but not filed retuns

Did you file cancellation of of gst
and if yes then after getting the cancellation order did you fill the annual return or say your final return with in the due date?

Cancellation of GST registration is not filed. GSTR 3B filed upto 31.03.'19. No other returns filed.

If you closed the business and no intention of doing it then you have to cancelled your GST as well as file GSTR10 so that the department know that you stop the business
otherwise you have to file your gst the way you filing earlier
file nil return till now if you made no purchase and sales transaction then cancel your registration after receiving cancel order in protal GSTR10 due date will appear then file with in that date .

My question is While filing the monthly return will I be liable pay late fee

Yes you will pay late fees

Thanks
