Idaho Code § 63-701
As used in this chapter:
(1) "Claimant" means a person who has filed an application under section 63-602G, Idaho Code, and has filed a claim under the provisions of sections 63-701 through 63-710, Idaho Code. Except as provided in section 63-702(2), Idaho Code, on January 1 or before April 15 of the year in which the claimant first filed a claim on the homestead in question, a claimant must be an owner of the homestead, a claimant must have lawful presence in the United States pursuant to section 67-7903, Idaho Code, and on January 1 of said year a claimant must be:
(5) "Income" means the sum of federal adjusted gross income as defined in the Internal Revenue Code, as defined in section 63-3004, Idaho Code, and to the extent not already included in federal adjusted gross income:
(g) The gross amount of loss of earnings insurance.
It does not include gifts from nongovernmental sources or inheritances. To the extent not reimbursed, the cost of medical care as defined in section 213(d) of the Internal Revenue Code, incurred and paid by the claimant and, if married, the claimant’s spouse, may be deducted from income. To the extent not reimbursed, personal funeral expenses, including prepaid funeral expenses and premiums on funeral insurance, of the claimant and claimant’s spouse only, may be deducted from income up to an annual maximum of five thousand dollars ($5,000) per claim. "Income" does not include veterans disability pensions received by a person described in subsection (1)(e) of this section who is a claimant or a claimant’s spouse if the disability pension is received pursuant to a service-connected disability of a degree of forty percent (40%) or more. "Income" does not include dependency and indemnity compensation or death benefits paid to a person described in subsection (1) of this section by the United States department of veterans affairs and arising from a service-connected death or disability. "Income" does not include lump sum death benefits made by the social security administration pursuant to 42 U.S.C. 402(i). Documentation of medical expenses may be required by the county assessor and state tax commission in such form as the county assessor or state tax commission shall determine. For purposes of this chapter only and in the case of a claimant who owns and whose homestead is a certified family home as defined in section 39-3502, Idaho Code, "income" does not include payments that the claimant received as an enrolled medicaid provider from the medical assistance program. "Income" shall be that received in the calendar year immediately preceding the year in which a claim is filed. Where a claimant and/or the claimant’s spouse does not file a federal tax return, the claimant’s and/or the claimant’s spouse’s federal adjusted gross income, for purposes of this section, shall be an income equivalent to federal adjusted gross income had the claimant and/or the claimant’s spouse filed a federal tax return, as determined by the county assessor. The county assessor or state tax commission may require documentation of income in such form as each shall determine, including, but not limited to: copies of federal or state tax returns and any attachments thereto; and income reporting forms such as the W-2 and 1099.
For determining income for certain married individuals living apart, the provisions of sections 2(c) and 7703(b) of the Internal Revenue Code shall apply.
(7) "Owner" means a person holding title in fee simple or holding a certificate of motor vehicle title (either of which may be subject to mortgage, deed of trust or other lien) or who has retained or been granted a life estate or who is a person entitled to file a claim under section 63-702, Idaho Code. "Owner" shall also include any person who:
(c) Has retained or been granted a life estate.
"Owner" includes a vendee in possession under a land sale contract. Any partial ownership shall be considered as ownership for determining initial qualification for property tax reduction benefits; however, the amount of property tax reduction under section 63-704, Idaho Code, and rules promulgated pursuant to section 63-705, Idaho Code, shall be computed on the value of the claimant’s partial ownership. "Partial ownership," for the purposes of this section, means any one (1) person’s ownership when property is owned by more than one (1) person or where the homestead is held by an entity, as set forth in this subsection, but more than one (1) person has the right of occupancy of such homestead. A person holding either partial title in fee simple or holding a certificate of motor vehicle title together with another person, but who does not occupy the dwelling as his primary dwelling place, shall not be considered an owner for purposes of this section, if such person is a cosignatory of a note secured by the dwelling in question and at least one (1) of the other cosignatories of the note occupies the dwelling as his primary dwelling place. The combined community property interests of both spouses shall not be considered partial ownership as long as the combined community property interests constitute the entire ownership of the homestead, including where the spouses are occupying a homestead owned by an entity, as set forth in this subsection, and the spouses have the primary right of occupancy of the homestead. The proportional reduction required under this subsection shall not apply to community property interests. Where title to property was held by a person who has died without timely filing a claim for property tax reduction, the estate of the deceased person shall be the "owner," provided that the time periods during which the deceased person held such title shall be attributed to the estate for the computation of any time periods under subsection (8)(a) or (b) of this section.

(a) "Primary dwelling place" means the claimant’s dwelling place on January 1 or before April 15 of the year for which the claim is made. The primary dwelling place is the single place where a claimant has his true, fixed and permanent home and principal establishment, and to which whenever the individual is absent he has the intention of returning. A claimant must establish the dwelling to which the claim relates to be his primary dwelling place by clear and convincing evidence or by establishing that the dwelling is where the claimant resided on January 1 or before April 15 and:
