Liability to pay GST after the cancellation of registration

If he has purchased from registered dealer he has paid tax
..
then he has unsold stock.
he can either sale it .
remain as it is.
while submitting returns he has to declare in his return.
It is advisable not to cancel registration.
Change the objects of business and apply for new business.
wait for sometime...

But situation is he has unsold stock which he has to sell out. Registration is cancelled. Now whether he is liable for GST on sale or not???

That stock is gst paid...

it is not a manufacturing business.
there is no value addition.

So u mean there is no liability of GST????

If A person took the registration voluntarily in composition scheme. Later on, he voluntarily cancelled the registration because his turnover is less than 40 lakh.

In this case, he is liable to pay GST on closing stock which he purchased while he was registered in GST and taken ITC of same in GSTR 3B return at time of cancellation of registration itself, not when he sold that stock in future.
You have to pay GST on remaining stock at time of cancellation if ITC is taken

Note: Above is for normal Taxpayer, if you are composition taxpayer than there is no liability.

Since the query has already mentioned that turnover is less then 40 lakhs
and assumed it is a trading business.
closing stock is tax paid.

@ Sabyasachi ji
"Closing stock is tax paid"
Than you means to say that for composition tax payers on cancellation , no need to pay GST on closing stock ??
