(c) Notwithstanding subdivision (a), during any period that Section 362 of Title 11 of the United States Code applies, any tax lien that would otherwise attach to property by reason of subdivision (a) shall not take effect, unless the tax is a debt of the debtor that will not be discharged in the bankruptcy proceeding and the property or its proceeds are transferred out of the bankruptcy estate to, or otherwise revested in, the debtor.
