The remedies in G.S. 105-241.11 through G.S. 105-241.18 set out the exclusive remedies for disputing the denial of a requested refund, a taxpayer's liability for a tax, or the constitutionality of a tax statute. Any other action is barred. Neither an action for declaratory judgment, an action for an injunction to prevent the collection of a tax, nor any other action is allowed.
