(a) The department shall, in determining need, take into consideration any income or resources of any relative claiming aid to families with dependent children, whose needs the department determines would be considered in determining the need of a child or relative claiming such aid, as well as any expense reasonably attributed to the earning of any such income.

(b) Income, as used in subsection (a), includes any benefit in cash which is in fact currently available to the individual or is received by him as a result of current or past labor or service, or business activities.

(c) To be considered in determining eligibility for, and amount of grant, income must, in fact, be currently available to the applicant or recipient. However, the applicant or recipient shall, as a necessary condition of determining eligibility:

(1) provide all information necessary to income determination;

(2) take all actions necessary to obtain unconditionally available income. Income shall be considered unconditionally available if the applicant or recipient has only to claim or accept such income, including any type of governmental benefits, social insurance, and private pension or benefits plan.

(d) The department shall require evidence which establishes the gross and net amount of income received and the time and frequency of receipt. Documents and records in the possession of the applicant or recipient together with a written statement made under penalty of perjury that such information is correct and complete to the best of the applicant or recipient’s knowledge or belief constitute adequate sources of evidence in absence of conflicts. Such documents or records shall be returned promptly to the applicant or recipient after necessary copies have been made and placed in the case records.
