(1) Until the state treasurer certifies that the assets in the nongame fish and wildlife trust fund created in the nongame fish and wildlife trust fund act exceed $6,000,000.00, a taxpayer may designate on his or her annual return that a contribution of $2.00 or more of his or her refund be credited to the state of Michigan nongame fish and wildlife trust fund created in part 439 (nongame fish and wildlife trust fund) of the natural resources and environmental protection act, Act No. 451 of the Public Acts of 1994, being section 324.43901 to 324.43907 of the Michigan Compiled Laws. If a taxpayer’s refund is not sufficient to make a contribution under this section, the taxpayer may designate a contribution amount and that contribution amount shall be added to the taxpayer’s tax liability for the tax year.

    (2) The contribution designation authorized in this section shall be clearly and unambiguously printed on the first page of all state individual income tax return forms, if practicable.

    (3) Notwithstanding the other allocations and disbursements required by this act, an amount equal to the cumulative designations made under this section, less the amount appropriated to the department of treasury for the purpose of implementing this section, shall be deposited in the state of Michigan nongame fish and wildlife trust fund and shall be appropriated solely for the purposes of the fund.
