§ 475. General powers of the tax commission. The powers conferred upon the tax commission by sections one hundred seventy-one and one hundred seventy-one-b of this chapter shall, so far as applicable, be exercisable with respect to the provisions of this article. Such commission may require returns to be filed with it at such times and containing such information as it may prescribe and in such event the fact that a person's name is signed to the return shall be prima facie evidence for all purposes that the return was actually signed by such person. Notwithstanding any other provision of this article, the tax commission may enter into an agreement with any city of this state which is authorized to impose a tax similar to that imposed by this article to provide for the joint administration, in whole or in part, of such taxes.
