Property Factor The property factor is a fraction, the numerator of which is the average value of the corporation’s real and tangible personal property owned or rented and used in this State during the income year and the denominator of which is the average value of all the corporation’s real and tangible personal property owned or rented and used during the income year. The numerator includes not only inventories actually located in North Carolina but also inventories in transit with a North Carolina destination. Property owned by the corporation is valued at its original cost. Property rented by the corporation is valued at eight times the net rent paid during the current income year. Net annual rent is the annual rent paid by the corporation less any annual rent received by the corporation from subrentals except that subrentals are not deductible when they constitute apportionable income. Any property under construction or any property not actually used or operated in the corporation’s business during the income year and any property the income from which constitutes nonapportionable income are excluded in the computation of the property factor. The average value of property is determined by averaging the values at the beginning and end of the income year, but in all cases the Secretary may require the averaging of monthly or other periodic values during the income year if required to reflect properly the average value of the corporation’s property. A corporation that ceases its operation in this State before the end of its income year for any reason whatsoever must use property values as of the first day of the income year and the last day of its operations in this State in determining the average value of property; however, the Secretary may require the averaging of monthly or other periodic values during the income year.
