An authority or developer shall semiannually submit to said commissioner a sworn statement setting forth such information with respect to the tenants and rentals for each housing project hereunder and the costs of operating each housing project under its jurisdiction as said commissioner requires. Any person who makes a false statement concerning the income of the family for which application for admission to or continued occupancy of housing projects is made may be fined not more than five hundred dollars or imprisoned not more than six months or both.

However, if a family's income has decreased, nothing in this section shall preclude an interim recertification
