A homeowner is eligible for the full benefits identical to the benefits of the repealed law in any taxable year that the homeowner meets the requirements of the repealed law.

A homeowner shall receive a property tax credit under this section equal to the greater of the 2 amounts calculated under subsection (d) of this section. If a surviving spouse of a homeowner has not remarried and meets the qualifications of the repealed law except for age or disability, the property tax credit under this section is available to the unmarried surviving spouse.
