(d) In determining the amount of premiums taxable in this state, all premiums written, procured, or received in this state shall be considered written on property or a subject located or resident in this state, except premiums that are properly allocated or apportioned and reported as taxable premiums of another state. In determining the amount of gross premiums taxable in this state, the tax due shall be computed on that portion of the policy premium that is attributable to a subject resident, located, or to be performed in this state and that relates to the kind of insurance being placed as determined by reference to an allocation schedule as follows:
(1) if a policy covers more than one classification,
- (A) for any portion of the coverage identified by a classification on the allocation schedule, the tax shall be computed by using the allocation schedule for the corresponding portion of the premium;
- (B) for any portion of the coverage not identified by a classification on the allocation schedule, the tax shall be computed by using an alternative equitable method of allocation for the property or subject;
- (C) for any portion of the coverage where the premium is indivisible, the tax shall be computed by using the method of allocation that pertains to the classification describing the predominant coverage;
(2) if the information provided is insufficient to substantiate the method of allocation used, or if the director determines that the method is incorrect, the director shall determine the equitable and appropriate amount of tax due to this state as follows:
- (A) by use of the allocation schedule where the subject is appropriately identified in the schedule;
- (B) where the allocation schedule does not identify a classification appropriate to the coverage, the director may give significant weight to documented evidence of the underwriting bases and other criteria used by the insurer or may give consideration to other available information to the extent sufficient and relevant, including the percentage of the insured's physical assets in this state, the percentage of the insured's sales in this state, the percentage of income or resources derived from this state, and the amount of premium tax paid to another jurisdiction for the policy.
