You are not eligible for the VCES Scheme, rather no meaning in thinking of it.
Under VCES a declaration can be made only in respect of “tax dues”. A case where no tax is pending, but return has not been filed, does not come under the ambit of the Scheme. However, rule 7C of the Service Tax Rules provides for waiver of penalty in deserving cases where return has not been filed and, in such cases, you may seek relief under rule 7C.
