This section does not apply to electric companies or combined companies, or to electric light companies for which an election made under Ohio R.C. 5745.031 is in effect.
(A) In the taxation of income which is subject to municipal income taxes, if the books and records of a taxpayer conducting a business or profession both within and without the boundaries of a municipal corporation shall disclose with reasonable accuracy what portion of its net profit is attributable to that part of the business or profession conducted within the boundaries of the municipal corporation, then only such portion shall be considered as having a taxable situs in such municipal corporation for purposes of municipal income taxation. In the absence of such records, net profit from a business or profession conducted both within and without the boundaries of a municipal corporation shall be considered as having a taxable situs in such municipal corporation for purposes of municipal income taxation in the same proportion as the average ratio of:
(1) The average net book value of the real and tangible personal property owned or used by the taxpayer in the business or profession in such municipal corporation during the taxable period to the average net book value of all of the real and tangible personal property owned or used by the taxpayer in the business or profession during the same period, wherever situated.
As used in the preceding paragraph, real property shall include property rented or leased by the taxpayer and the value of such property shall be determined by multiplying the annual rental thereon by eight;
(2) Wages, salaries, and other compensation paid during the taxable period to persons employed in the business or profession for services performed in such municipal corporation to wages, salaries, and other compensation paid during the same period to persons employed in the business or profession, wherever their services are performed excluding compensation that is not taxable by the municipal corporation under Ohio R.C. 718.011;
(3) Gross receipts of the business or profession from sales made and services performed during the taxable period in such municipal corporation to gross receipts of the business or profession during the same period from sales and services, wherever made or performed.
In the event that the foregoing allocation formula does not produce an equitable result, another basis may, under uniform regulations, be substituted so as to produce such result.
(B) As used in division (A) of this section, "sales made in a municipal corporation" means:
(1) All sales of tangible personal property which is delivered within such municipal corporation regardless of where title passes if shipped or delivered from a stock of goods within such municipal corporation;
(2) All sales of tangible personal property which is delivered within such municipal corporation regardless of where title passes even though transported from a point outside such municipal corporation if the taxpayer is regularly engaged through its own employees in the solicitation or promotion of sales within such municipal corporation and the sales result from such solicitation or promotion;
(3) All sales of tangible personal property which is shipped from a place within such municipal corporation to purchasers outside such municipal corporation regardless of where title passes if the taxpayer is not, through its own employees, regularly engaged in the solicitation or promotion of sales at the place where delivery is made.
