If the net income of a corporation, financial institution, or unincorporated business, or the unrelated business income of an exempt organization, is derived from sources within and without the District, the taxpayer shall apportion business income and allocate non-business income as provided in this section.

(c) Allocation of nonbusiness income. —

(1) Rents and royalties from real or tangible personal property, capital gains, interest, dividends, or patent or copyright royalties, to the extent that they constitute non-business income, shall be allocated as provided in paragraphs (2), (3), (4), and (5) of this subsection.

(2)

(A) Net rents and royalties from real property located in the District are allocable to the District.

(B) Net rents and royalties from tangible personal property are allocable to the District:

(ii) In their entirety if the taxpayer’s commercial domicile is in the District and the taxpayer is not organized under the laws of or taxable in the state in which the property is utilized.

(C) The extent of utilization of tangible personal property in a state is determined by multiplying the rents and royalties by a fraction, the numerator of which is the number of days of physical location of the property in the state during the rental or royalty period in the taxable year and the denominator of which is the number of days of physical location of the property everywhere during all rental or royalty periods in the taxable year. If the physical location of the property during the rental or royalty period is unknown or unascertainable by the taxpayer, the tangible personal property is utilized in the state in which the property was located at the time the rental or royalty payer obtained possession.

(3)

(A) Capital gains and losses from sales of real property located in the District are allocable to the District.

(B) Capital gains and losses from sales of tangible personal property are allocable to the District if:

(B) A patent is utilized in a state to the extent that it is employed in production, fabrication, manufacturing, or other processing in the state to the extent that a patented product is produced in the state. If the basis of receipts from patent royalties does not permit allocation to states or if the accounting procedures do not reflect states of utilization, the patent is utilized in the state in which the taxpayer’s commercial domicile is located.

(C) A copyright is utilized in a state to the extent that printing or other publication originates in the state. If the basis of receipts from copyright royalties does not permit allocation to states or if the accounting procedures do not reflect states of utilization, the copyright is utilized in the state in which the taxpayer’s commercial domicile is located.

(d) Apportionment of business income. — Except as provided in subsection (d-1) or (d-2), whichever is applicable, all business income shall be apportioned to the District by multiplying the income by a fraction, the numerator of which is the property factor plus the payroll factor plus the sales factor, and the denominator of which is 3.

(d-1) Apportionment of business income. —

(1) All business income shall be apportioned to the District by multiplying the income by a fraction, the numerator of which is the property factor plus the payroll factor plus the sales factor twice, and the denominator of which is 4.
