Such determination shall be made as of the date shown by the report to have been the beginning of the corporation's annual accounting period that includes the first day of January of the tax year. The total value, as shown by the books of the financial institution, of its capital, surplus, whether earned or unearned, undivided profits, and reserves shall be determined as prescribed by section 5733.056 of the Revised Code for tax years 1998 and thereafter. The net income allocated to this state as provided by section 5733.051 of the Revised Code. The amount of Ohio apportioned net income from sources other than those allocated under section 5733.051 of the Revised Code, which shall be determined by multiplying the corporation's net income by a fraction. The denominator of the fraction is one hundred, provided that the denominator shall be reduced by twenty if the property factor has a denominator of zero, by twenty if the payroll factor has a denominator of zero, and by sixty if the sales factor has a denominator of zero.
Property rented by the corporation is valued at eight times the net annual rental rate.
The average value of property shall be determined by averaging the values at the beginning and the end of the taxable year, but the tax commissioner may require the averaging of monthly values during the taxable year, if reasonably required to reflect properly the average value of the corporation's property. The payroll factor is a fraction the numerator of which is the total amount paid in this state during the taxable year by the corporation for compensation, and the denominator of which is the total compensation paid everywhere by the corporation during such year. There shall be excluded from the numerator and the denominator of the payroll factor the total compensation paid in this state to employees who are primarily engaged in qualified research. The sales factor is a fraction the numerator of which is the total sales in this state by the corporation during the taxable year, and the denominator of which is the total sales by the corporation everywhere during such year. In determining the numerator and denominator of the sales factor, receipts from the sale or other disposal of a capital asset or an asset described in section 1231 of the Internal Revenue Code shall be eliminated.
