(b) Due to the administrative cost of processing, the refundable credit authorized by this section may not be refunded if less than $10.
(c) The credit for each property tax year shall be claimed by filing a claim for refund within twelve months after the real property taxes are paid on the homestead.
(d) For the purposes of this section:
(1) "Gross household income" is defined as federal adjusted gross income plus the sum of the following:
(A) Modifications in subsection (b), section twelve of this article increasing federal adjusted gross income;
(B) Federal tax-exempt interest reported on federal tax return;
(C) Workers' compensation and loss of earnings insurance; and
(D) Nontaxable Social Security benefits; and
(2) For the tax years beginning before January 1, 2008, "real property taxes paid" means the aggregate of regular levies, excess levies and bond levies extended against the homestead that are paid during the calendar year and determined after any application of any discount for early payment of taxes but before application of any penalty or interest for late payment of property taxes for property tax years that begin on or after January 1, 2008.
(e) A homeowner is eligible to benefit from this section or section twenty-one of this article, whichever section provides the most benefit as determined by the homeowner. No homeowner may receive benefits under both this section and section twenty-one of this article during the same taxable year. For tax years beginning on and after January 1, 2009, any person who is required to pay the federal alternative minimum income tax in the current tax year is disqualified from receiving any tax credit provided under this section. Nothing in this section denies those entitled to the homestead exemption provided in section three, article six-b of this chapter.
(f) No homeowner may receive a refundable tax credit imposed by this article in excess of $1,000. This amount shall be reviewed annually by the Legislature to determine if an adjustment is necessary.
