The assessor may require taxpayers to provide information on tax returns on property value and factor. The property factor also may be used in appropriate circumstances in determining an apportionment variation, as provided under 36 M.R.S. §5211(17). The property factor is a fraction, the numerator of which is the average value of the taxpayer's real and tangible personal property owned or rented and used in Maine during the tax period, and the denominator of which is the average value of all the taxpayer's real and tangible personal property owned or rented and used during the tax period.
Generally, the average value of all property owned by the taxpayer is determined by averaging the values at the beginning and ending of the tax period. However, the assessor may require or allow averaging of monthly values if substantial fluctuations in the values of the property exist during the taxable year or if property is acquired after the beginning of the taxable year or disposed of before the end of the taxable year.
If property is used at no charge or rented for a rate other than a reasonable market rate, the property must be included in the property factor on the basis of a reasonable market rental rate.
The "annual rental rate" is the amount paid as rent for the property for a twelve-month period. When property is rented for less than a twelve-month period, the net rent paid for the actual period of rental constitutes the "annual rental rate" for the tax period.
However, when a taxpayer has rented property for a term of 12 or more months and the current tax period covers a period of less than 12 months, the net rent paid for the short tax period must be annualized. If the rental term is for less than 12 months, the rent must not be annualized beyond its term. Rent will not be annualized because of the uncertain duration when the rental term is on a month-to-month basis.
"Rent" is the actual sum of money or other consideration payable, directly or indirectly, by the taxpayer or for its benefit for the use of the property and includes:
"Rent" does not include incidental day-to-day expenses such as hotel or motel accommodations, daily rental of automobiles, etc. "Rent" does not include royalties based on extraction of natural resources, whether represented by delivery or purchase. For this purpose, a royalty includes any consideration conveyed or credited to a holder of an interest in property that constitutes a sharing of current or future production of natural resources from such property, irrespective of the method of payment or how such consideration may be characterized, whether as a royalty, advance royalty, rental or otherwise.
Leasehold improvements are treated as property owned by the taxpayer regardless of whether the taxpayer is entitled to remove the improvements or of whether the improvements revert to the lessor upon expiration of the lease.
