(b)    In computing Maryland taxable income, a corporation shall allocate Maryland modified income derived from or reasonably attributable to its trade or business in this State in the following manner:
(1)    if a corporation carries on its trade or business wholly within the State, the corporation shall allocate to the State all of the Maryland modified income of the corporation; and
(2)    if a corporation carries on its trade or business within and outside the State, the corporation shall allocate to the State the part of the corporation’s Maryland modified income that is derived from or reasonably attributable to the part of its trade or business carried on in the State, in the manner required in subsection (c), (d), or (e) of this section.
(c)    (1)    Except as provided in subsection (d) or (e) of this section, the part of the corporation’s Maryland modified income derived from or reasonably attributable to trade or business carried on in the State may be determined by separate accounting if practicable.
(2)    If in any taxable year a corporation is permitted or required to use the separate accounting method in determining all or a portion of its Maryland taxable income, the portion that is separately accounted for to Maryland shall be taxable whether or not the Maryland modified income of the corporation for the taxable year is zero or less.
(d)    (1)    (i)    In this paragraph:
1.    “manufacturing corporation” means a domestic or foreign corporation which is primarily engaged in activities that, in accordance with the North American Industrial Classification System (NAICS), United States Manual, United States Office of Management and Budget, 1997 Edition, would be included in Sector 11, 31, 32, or 33; and
2.    “manufacturing corporation” does not include a refiner, as defined in § 10–101 of the Business Regulation Article.
(ii)    If a manufacturing corporation carries on its trade or business within and outside the State and the trade or business is a unitary business, the part of the corporation’s Maryland modified income derived from or reasonably attributable to trade or business carried on in the State shall be determined using a single sales factor apportionment formula, by multiplying its Maryland modified income by 100% of the sales factor.
(iii)    In filing its tax return for each year, a manufacturing corporation shall certify that the NAICS Code reported on its Maryland return is consistent with that reported to other government agencies.
(iv)    If the Comptroller determines that a corporation has submitted information that incorrectly classifies the corporation as a manufacturing corporation under subparagraph (i) of this paragraph, the Comptroller shall reclassify the corporation in an appropriate manner.
(2)    Except as provided in paragraphs (1) and (3) of this subsection:
(i)    for a taxable year beginning after December 31, 2017, but before January 1, 2019, if the trade or business is a unitary business, the part of the corporation’s Maryland modified income derived from or reasonably attributable to trade or business carried on in the State shall be determined using a 3–factor apportionment fraction:

2.    the denominator of which is 7;
(iv)    for a taxable year beginning after December 31, 2020, but before January 1, 2022, if the trade or business is a unitary business, the part of the corporation’s Maryland modified income derived from or reasonably attributable to trade or business carried on in the State shall be determined using a 3–factor apportionment fraction:
1.    the numerator of which is the sum of the property factor, the payroll factor, and 6 times the sales factor; and
2.    the denominator of which is 8; and
(v)    for a taxable year beginning after December 31, 2021, if the trade or business is a unitary business, the part of the corporation’s Maryland modified income derived from or reasonably attributable to trade or business carried on in the State shall be determined using a single sales factor apportionment formula, by multiplying its Maryland modified income by 100% of the sales factor.
(3)    (i)    Each year a worldwide headquartered company that filed a federal corporate income tax return for the taxable year may elect to calculate its Maryland modified income derived from or reasonably attributable to trade or business carried on in the State using a 3–factor apportionment fraction:

2.    the denominator of which is 4.
(ii)    To determine under subparagraph (i) of this paragraph the Maryland modified income of a corporation or group of corporations that is a worldwide headquartered company that filed a federal corporate income tax return for the taxable year, gross income from intangible investments, including dividends, interest, royalties, and capital gains from the sale of intangible property, shall be included in the calculation of the numerator based on the average of the property and payroll factors.

(4)    the valuation of rented property included in the property factor; and
(5)    the determination of the extent to which tangible personal property is located in the State.
