Ariz. Admin. Code § 15-2D-507
Current through Register Vol. 30, No. 50, December 13, 2024
In most cases an allowable deduction of a taxpayer will be applicable only to the business income arising from a particular trade or business or to a particular item of nonbusiness income. In some cases an allowable deduction may apply to the business incomes of more than one trade or business or to several items of nonbusiness income. In these cases the deduction shall be prorated among the trades or businesses and the items of nonbusiness income in a manner that fairly distributes the deduction among the classes of income to which it applies.
