1.     a.    Any person sixty-five years of age or older or permanently and totally disabled, in the year in which the tax was levied, with an income that does not exceed the limitations of subdivision c is entitled to receive a reduction in the assessment on the taxable valuation on the person’s homestead. An exemption under this subsection applies regardless of whether the person is the head of a family.

b.    The exemption under this subsection continues to apply if the person does not reside in the homestead and the person’s absence is due to confinement in a nursing home, hospital, or other care facility, for as long as the portion of the homestead previously occupied by the person is not rented to another person.

c.    The exemption must be determined according to the following schedule:

(1) If the person’s income is not in excess of forty thousand dollars, a reduction of one hundred percent of the taxable valuation of the person’s homestead up to a maximum reduction of nine thousand dollars of taxable valuation.

(2) If the person’s income is in excess of forty thousand dollars and not in excess of seventy thousand dollars, a reduction of fifty percent of the taxable valuation of the person’s homestead up to a maximum reduction of four thousand five hundred dollars of taxable valuation.

d.    Persons residing together, as spouses or when one or more is a dependent of another, are entitled to only one exemption between or among them under this subsection. Persons residing together, who are not spouses or dependents, who are co-owners of the property are each entitled to a percentage of a full exemption under this subsection equal to their ownership interests in the property.

e.    This subsection does not reduce the liability of any person for special assessments levied upon any property.

f.    Any person claiming the exemption under this subsection shall sign a verified statement of facts establishing the person’s eligibility. Any income information contained in the statement of facts is a confidential record.

g.    The assessor shall attach the statement filed under subdivision f to the assessment sheet and shall show the reduction on the assessment sheet.

h.    An exemption under this subsection terminates at the end of the taxable year of the death of the applicant.

2.     a.    Any person who would qualify for an exemption under subdivisions a and c of subsection 1 except for the fact that the person rents living quarters is eligible for    refund of a portion of the person’s annual rent deemed by this subsection to constitute the payment of property tax.

b.    For the purpose of this subsection, twenty percent of the annual rent, exclusive of any federal rent subsidy and of charges for any utilities, services, furniture, furnishings, or personal property appliances furnished by the landlord as part of the rental agreement, whether expressly set out in the rental agreement, must be considered as payment made for property tax. When any part of the twenty percent of the annual rent exceeds four percent of the annual income of a qualified applicant, the applicant is entitled to receive a refund from the state general fund for that amount in excess of four percent of the person’s annual income, but the refund may not be in excess of four hundred dollars. If the calculation for the refund is less than five dollars, a minimum of five dollars must be sent to the qualifying applicant.

c.    Persons who reside together, as spouses or when one or more is a dependent of another, are entitled to only one refund between or among them under this subsection. Persons who reside together in a rental unit, who are not spouses or dependents, are each entitled to apply for a refund based on the rent paid by that person.

d. Each application for refund under this subsection must be made to the tax commissioner before the first day of June of each year by the person claiming the refund. The tax commissioner may grant an extension of time to file an application for good cause. The tax commissioner shall issue refunds to applicants.

e.    This subsection does not apply to rents or fees paid by a person for any living quarters, including a nursing home licensed pursuant to section 23-16-01, if those living quarters are exempt from property taxation and the owner is not making a payment in lieu of property taxes.

f.    A person may not receive a refund under this section for a taxable year in which that person received an exemption under subsection 1.

3.    All forms necessary to effectuate this section must be prescribed, designed, and made available by the tax commissioner. The county directors of tax equalization shall make these forms available upon request.

4.    A person whose homestead is a farm structure exempt from taxation under subsection 15 of section 57-02-08 may not receive any property tax credit under this section.
