3. As used in this section, unless the context otherwise requires, the following terms mean:
(1) "Apportionable income" :
(a) All income that is apportionable under the Constitution of the United States and is not allocated under the laws of this state, including:
a. Income arising from transactions and activity in the regular course of the corporation's trade or business; and
b. Income arising from tangible and intangible property if the acquisition, management, employment, development, or disposition of the property is or was related to the operation of the corporation's trade or business; and
(b) Any income that would be allocable to this state under the Constitution of the United States, but that is apportioned rather than allocated pursuant to the laws of this state;
(2) "Commercial domicile" , the principal place from which the trade or business of the corporation is directed or managed;
(3) "Financial organization" , any bank, trust company, savings bank, industrial bank, land bank, safe deposit company, private banker, savings and loan association, credit union, cooperative bank, small loan company, sales finance company, investment company, or any type of insurance company;
(4) "Nonapportionable income" , all income other than apportionable income;
(5) "Public utility" , any business entity:
(a) Which owns or operates any plant, equipment, property, franchise, or license for the transmission of communications, transportation of goods or persons, except by pipeline, or the production, transmission, sale, delivery, or furnishing of electricity, water or steam; and
(b) Whose rates of charges for goods or services have been established or approved by a federal, state, or local government or governmental agency;
(6) "Receipts" , all gross receipts of the corporation that are not allocated under the provisions of this section, and that are received from transactions and activity in the regular course of the corporation's trade or business; except that receipts of a corporation from hedging transactions and from the maturity, redemption, sale, exchange, loan or other disposition of cash or securities, shall be excluded.
4. For purposes of allocation and apportionment of income under this section, a corporation is taxable in another state if:
(1) In that state it is subject to a net income tax, a franchise tax measured by net income, a franchise tax for the privilege of doing business, or a corporate stock tax; or
(2) That state has jurisdiction to subject the corporation to a net income tax regardless of whether, in fact, the state does or does not do so.
5. Rents and royalties from real or tangible personal property, capital gains, interest, dividends or patent or copyright royalties, to the extent that they constitute nonapportionable income, shall be allocated as provided in subsections 6 to 9 of this section.
6. (1) Net rents and royalties from real property located in this state are allocable to this state.
(2) Net rents and royalties from tangible personal property are allocable to this state:
(a) If and to the extent the property is utilized in this state; or
(b) In their entirety if the corporation's commercial domicile is in this state and the corporation is not organized under the laws of or taxable in the state in which the property is utilized.
(3) 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 corporation, tangible personal property is utilized in the state in which the property was located at the time the rental or royalty payer obtained possession.
7. (1) Capital gains and losses from sales of real property located in this state are allocable to this state.
(2) Capital gains and losses from sales of tangible personal property are allocable to this state if:
(a) The property had a situs in this state at the time of the sale; or
(b) The corporation's commercial domicile is in this state and the corporation is not taxable in the state in which the property had a situs.
(3) Capital gains and losses from sales of intangible personal property are allocable to this state if the corporation's commercial domicile is in this state.
8. Interest and dividends are allocable to this state if the corporation's commercial domicile is in this state.
9. (1) Patent and copyright royalties are allocable to this state:
(a) If and to the extent that the patent or copyright is utilized by the payer in this state; or
(b) If and to the extent that the patent or copyright is utilized by the payer in a state in which the corporation is not taxable and the corporation's commercial domicile is in this state.
(2) A patent is utilized in a state to the extent that it is employed in production, fabrication, manufacturing, or other processing in the state or 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 corporation's commercial domicile is located.
(3) 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 corporation's commercial domicile is located.
10. All apportionable income shall be apportioned to this state by multiplying the net income by a fraction, the numerator of which is the total receipts of the corporation in this state during the tax period and the denominator of which is the total receipts of the corporation everywhere during the tax period.
11. Receipts from the sale of tangible personal property are in this state if the property is received in this state by the purchaser. In the case of the delivery of goods by common carrier or by other means of transportation, including transportation by the purchaser, the place at which the goods are ultimately received after all transportation has been completed shall be considered as the place at which the goods are received by the purchaser. Direct delivery into this state by the taxpayer to a person or firm designated by a purchaser from within or without the state shall constitute delivery to the purchaser in this state.

a. That is rented, leased, or licensed, if and to the extent the property is used in this state, provided that intangible property utilized in marketing a good or service to a consumer is "used in this state" if that good or service is purchased by a consumer who is in this state. Franchise fees or royalties received for the rent, lease, license, or use of a trade name, trademark, service mark, or franchise system or provides a right to conduct business activity in a specific geographic area "are used in this state" to the extent the franchise is located in this state; and

(a) Separate accounting;
(b) The inclusion of one or more additional factors which will fairly represent the corporation's income applicable to this state; or
(c) The employment of any other method to effectuate an equitable allocation and apportionment of the corporation's income.
(3) The party petitioning for, or the director requiring, the use of any method to effectuate an equitable allocation and apportionment of the corporation's income pursuant to subdivision (2) of this subsection shall prove by a preponderance of evidence:
(a) That the allocation and apportionment provisions of this section do not fairly represent the extent of the corporation's income applicable to this state; and
(b) That the alternative to such provisions is reasonable.
(4) If the director requires any method to effectuate an equitable allocation and apportionment of the corporation's income, the director cannot impose any civil or criminal penalty with reference to the tax due that is attributable to the corporation's reasonable reliance solely on the allocation and apportionment provisions of this section.
(5) A corporation that has received written permission from the director to use a reasonable method to effectuate an equitable allocation and apportionment of the corporation's income shall not have that permission revoked with respect to transactions and activities that have already occurred unless there has been a material change in, or a material misrepresentation of, the facts provided by the corporation upon which the director reasonably relied.
14. Any corporation described in subdivision (1) of subsection 1 of section 143.441 organized in this state or granted a permit to operate in this state for the transportation or care of passengers shall report its gross earnings within the state on intrastate business and shall also report its gross earnings on all interstate business done in this state. Such report shall be subject to inquiry for the purpose of determining the amount of income to be included in Missouri taxable income. This subsection shall not apply to a railroad.
15. A corporation described in subdivision (2) of subsection 1 of section 143.441 shall include in its Missouri taxable income all income arising from all sources in this state and all income from each transportation service wholly within this state, from each service where the only rails and lines of such corporation used are those in this state, and such proportion of revenue from each service where the facilities of such corporation in this state and in another state or states are used, as the mileage used over the rails and lines of such corporation in the state shall bear to the total mileage used over the rails and lines of such corporation. The corporation may elect to compute the portion of income from all sources within this state in the following manner:
(1) The income from all sources shall be determined as provided;
(2) The amount of investment of such corporation on December thirty-first of each year in this state in fixed transportation facilities, real estate and improvements, plus the value on December thirty-first of each year of any fixed transportation facilities, real estate and improvements in this state leased from any other railroad shall be divided by the sum of the total amount of investment of such corporation on December thirty-first of each year in fixed transportation facilities, real estate and improvements, plus the value on December thirty-first of each year, of any fixed transportation facilities, real estate and improvements leased from any other railroad. Where any fixed transportation facilities, real estate or improvements are leased by more than one railroad, such portion of the value shall be used by each railroad as the rental paid by each shall bear to the rental paid by all lessees. The income shall be multiplied by the fraction thus obtained to determine the proportion to be used to arrive at the amount of Missouri taxable income.
16. A corporation described in subdivision (3) of subsection 1 of section 143.441 shall include in its Missouri taxable income one-half of the net income from the operation of a bridge between this and another state. If any such bridge is owned or operated by a railroad corporation or corporations, or by a corporation owning a railroad corporation using such bridge, then the figures for operation of such bridge may be included in the return of such railroad or railroads; or if such bridge is owned or operated by any other corporation which may now or hereafter be required to file an income tax return, one-half of the income or loss to such corporation from such bridge may be included in such return by adding or subtracting the same to or from another net income or loss shown by the return.
17. A corporation described in subdivision (4) of subsection 1 of section 143.441 shall include in its Missouri taxable income all income arising from all sources within this state. Income shall include revenue from each telephonic or telegraphic service rendered wholly within this state; from each service rendered for which the only facilities of such corporation used are those in this state; and from each service rendered over the facilities of such corporation in this state and in other state or states, such proportion of such revenue as the mileage involved in this state shall bear to the total mileage involved over the lines of said company in all states. The corporation may elect to compute the portion of income from all sources within this state in the following manner:
(1) The income from all sources shall be determined as provided;
(2) The amount of investment of such corporation on December thirty-first of each year in this state in telephonic or telegraphic facilities, real estate and improvements thereon, shall be divided by the amount of the total investment of such corporation on December thirty-first of each year in telephonic or telegraphic facilities, real estate and improvements. The income of the corporation shall be multiplied by the fraction thus obtained to determine the proportion to be used to arrive at the amount of Missouri taxable income.
18. From the income determined in this section to be from all sources within this state shall be deducted such of the deductions for expenses in determining Missouri taxable income as were incurred in this state to produce such income and all losses actually sustained in this state in the business of the corporation.
19. If a corporation derives only part of its income from sources within Missouri, its Missouri taxable income shall only reflect the effect on Missouri taxable income of the deduction for net operating loss allowed by Section 172 of the Internal Revenue Code. The extent applicable to Missouri shall be determined by multiplying the amount that would otherwise affect Missouri taxable income by the ratio for the year of the Missouri taxable income of the corporation for the year divided by the Missouri taxable income for the year as though the corporation had derived all of its income from sources within Missouri. For the purpose of the preceding sentence, Missouri taxable income shall not reflect the deduction.
20. Any investment funds service corporation organized as a corporation or S corporation which has any shareholders residenced in this state shall be subject to Missouri income tax as provided in this chapter.
