In promulgating regulations under this subsection, the Secretary shall consult with the Secretary of Health and Human Services in order to assure that, to the extent feasible and consistent with the purposes of this chapter and the Social Security Act [ 42 U.S.C. 301 et seq.], the income of households receiving benefits under this chapter and title IV–A of the Social Security Act [ 42 U.S.C. 601 et seq.] is calculated on a comparable basis under this chapter and the Social Security Act. The Secretary is authorized, upon the request of a State agency, to waive any of the provisions of this subsection (except the provisions of paragraph (2)(A)) to the extent necessary to permit the State agency to calculate income for purposes of this chapter on the same basis that income is calculated under title IV–A of the Social Security Act in that State.
