Not filled nil service tax return because there is no work

dear ankit plz file all your pending returns before GST applicability. may be there will be any case ( as there in vat) where if tax is nil & penalty is also  nil. so file your return without paying penalty

So it means as your answer i need to asap file nil return within days so it will be good for me? and also i will not need to pay penalty. Right?

penalty is disputable case. but file the return first
