Notice of return for cancelled registration and closed business

Wait for the penalty waiving scheme...i think government is thinking regarding and will give opportunity in about September...so wait upto September..

Thank you sir for your reply
but the notice states to file the return within 15 days otherwise the tax liability will be assessed under section 63 of the act.
though there is no tax liability only penalty of 10 k has been imposed.
Is it going to impact my current business as my old as well as new one both are attached to my pan only. please help.

Yes .... correct the proceedings under Section 63 will be initiated 'Assessment under Best judgements' & in non compliance of notice the Officer can assess the tax liability based on his best judgement.

So, should I file the return with penalty for Nil GST of closed business within 15 days? or I should wait for the next step of Assessing officer?
wat would be the final consequence on my current business for non filing?

are you ready to accept the tax liability assess by tax officer .... why you want get into the litigation. so its my view better to complete all your compliance before 15 days
