Iowa Admin. Code r. 701-502.18
For tax years beginning on or after January 1, 1992, and before January 1, 2005, corporations may claim a deduction for 60 percent of the amount of the registration fee paid for a multipurpose vehicle under Iowa Code section 321.124, subsection 3, paragraph "h." In order to qualify for this deduction, no part of the multipurpose vehicle registration fee may have been deducted as an ordinary and necessary business expense.
For tax years beginning on or after January 1, 2005, the deduction for Iowa corporation income tax for multipurpose vehicle registration fees is the same as allowed under Section 164 of the Internal Revenue Code for federal tax purposes.
This rule is intended to implement Iowa Code section 422.35.
