63-3026A. COMPUTING IDAHO TAXABLE INCOME OF PART-YEAR OR NONRESIDENT INDIVIDUALS, TRUSTS AND ESTATES. (1) For nonresident individuals, trusts, or estates the term "Idaho taxable income" includes only those components of Idaho taxable income as computed for a resident which are derived from or related to sources within Idaho. This is to be computed without the deductions for either the standard deduction or itemized deductions or personal exemptions except as provided in subsection (4) of this section.

(2) For part-year resident individuals, trusts or estates the term "Idaho taxable income" includes the total of: (a) Idaho taxable income as computed for a resident for the portion of the tax period during which a taxpayer is domiciled in or is residing in Idaho, plus (b) those components of Idaho taxable income which are derived from or related to sources within Idaho for that portion of the tax period during which a taxpayer is not domiciled in and is not residing in Idaho. This is to be computed without the deductions for either the standard deduction or itemized deductions or personal exemptions except as provided in subsection (4) of this section.

(3) For the purposes of subsections (1) and (2) of this section:

(a) Income shall be considered derived from or relating to sources within Idaho when such income is attributable to or resulting from:

(i) Any business, trade, profession or occupation conducted or carried on in this state, including the distributive share of partnership income and deductions, and the pro rata share of S corporation income and deductions. Partnership income, including guaranteed payments pursuant to section 707 of the Internal Revenue Code, is sourced to Idaho based upon the Idaho apportionment factor of the partnership; excluding:

1. Guaranteed payment to a retired partner per 4 U.S.C. section 114(b)(1)(I) that is sourced to the recipient’s state of domicile;

2. Guaranteed payment to an individual partner up to two hundred fifty thousand dollars ($250,000) in any calendar year is sourced as compensation for services. The amount of the guaranteed payment in excess of two hundred fifty thousand dollars ($250,000) is sourced to Idaho based upon the partnership’s Idaho apportionment factor. The two hundred fifty thousand dollar ($250,000) amount will be adjusted annually by multiplying the amount by the percentage (the consumer price index for the calendar year immediately preceding the calendar year to which the adjusted amount will apply divided by the consumer price index for calendar year 2013) as defined in section 63-3024, Idaho Code;

(ii) The ownership or disposition of any interest in real or tangible personal property located in this state;

(iii) The ownership or disposition of any interest in intangible personal property only to the extent that such property is employed in a business, trade, profession or occupation conducted or carried on in this state. Provided however, that interest income from an installment sale of real or tangible personal property shall constitute income from sources within this state to the extent that the property sold was located within this state. Provided further, that interest income received by a partner or shareholder of a partnership or S corporation from such partnership or S corporation shall constitute income from sources within this state to the extent that the partnership or S corporation is transacting business within this state;

(iv) A resident estate or trust; provided however, that income distributed to beneficiaries of an estate or trust shall constitute income from sources within this state only to the extent the income would be Idaho source income if such income had been received directly by a nonresident individual;

(v) A nonresident estate or trust to the extent the income and deductions of the nonresident estate or trust were derived from or related to sources within this state;

(vi) The conduct of pari-mutuel wagering, charitable gaming or any other form of gambling taking place within this state, except as expressly limited in section 67-7439, Idaho Code;

(vii) Gains or losses realized from the sale or other disposition of a partnership interest or stock in an S corporation to the extent of the partnership’s or S corporation’s Idaho apportionment factor in the taxable year immediately preceding the year of sale. In the case of a nonresident individual who sells the nonresident’s interest in a publicly traded partnership defined in section 7704 of the Internal Revenue Code doing business in Idaho, the gains or losses shall be determined using the amount described in section 751 of the Internal Revenue Code, multiplied by the apportionment factor for the year in which the sale occurred.

(b) Notwithstanding the provisions of subsection (3)(a) of this section, transactions and investments made, placed or directed by Idaho resident registered broker-dealers and investment advisers or institutions exempt from registration under the Idaho securities act in securities listed with or through the New York Stock Exchange, the American Stock Exchange or any other stock exchange registered with the United States securities and exchange commission and approved by the director of the department of finance which generate dividends, interest, capital gains or similar profits or returns for nonresidents not otherwise subject to Idaho income taxation shall not result in the intangible property being deemed to have a situs outside the domicile of the owner.

(c) Nonresident individuals shall not be taxable on investment income from a qualified investment partnership. For purposes of this paragraph, a "qualified investment partnership" means a partnership, as defined in section 63-3006B, Idaho Code, that derives at least ninety percent (90%) of its gross income from investments that produce income that would not be taxable to a nonresident individual if the investment were held by that individual.

(d) Compensation paid by the United States for active service in the armed forces of the United States, performed by an individual not domiciled in this state, shall not constitute income derived from or related to sources within this state.

(e) The income of nonresident or part-year resident individuals, trusts or estates which is derived from or related to sources both within and without this state shall be attributable to this state in the manner prescribed in the rules of the state tax commission.

(4) In computing the Idaho taxable income of a part-year or nonresident individual, trust or estate, the standard deduction or itemized deductions, as defined in section 63-3022(j), Idaho Code, if applicable, and the exemptions, as defined in section 151 of the Internal Revenue Code or any allowance in lieu of such deduction, shall be allowed in the proportion that paragraph (a) of this subsection bears to paragraph (b) of this subsection:

(a) The Idaho taxable income of the taxpayer modified as follows:

(i) No allowance shall be made for either the standard deduction or itemized deductions;

(ii) No deduction shall be made for personal exemptions or any allowance in lieu of such deduction.

(b) The Idaho taxable income as would be calculated for a resident of Idaho modified as follows:

(i) No allowance shall be made for either a standard deduction or itemized deductions;

(ii) No deduction shall be made for personal exemptions or any allowance in lieu of such deduction;

(iii) Compensation for active military service in the armed forces shall not be deducted;

(iv) Income earned within the original exterior boundaries of any federally created Indian reservation by an enrolled Indian in a federally recognized Indian tribe on a federally recognized Indian reservation shall be added if not otherwise included.

(5) An adjustment may be made to eliminate distortions in the amount of net income attributable to a taxpayer’s activities within the state of Idaho. Such deductions shall be limited to circumstances involving itemized deductions as referred to in subsection (4) of this section and which reflect:

(a) A failure to reflect the net income or deduction after reimbursements have been received; or

(b) A failure to reflect the net amount of mortgage interest income or expense from activities within Idaho.

(6) For the purposes of subsections (1) and (2) of this section, deductions and adjustments allowed in computing the Idaho taxable income of nonresident and part-year resident individuals, trusts and estates shall be prescribed in the rules of the state tax commission. Such rules shall be based upon:

(a) Whether or not the deduction or adjustment is related to the production of income reportable to Idaho;

(b) Whether or not the deduction or adjustment is related to income received, expenses paid, or events of tax consequence which occurred during a portion of a taxable year that the taxpayer was domiciled in or residing in Idaho; or

(c) Any other appropriate basis for making the adjustment. An "appropriate basis" is one which the state tax commission finds is needed to insure that the amount of Idaho taxable income is fairly and reasonably related to a taxpayer’s activities in this state.
