Iowa Admin. Code r. 701—303.11(422) — Reduction in state itemized deductions for certain high-income taxpayers

For tax years beginning after December 31, 1990, the itemized deductions for certain high-income taxpayers are reduced for federal income tax purposes by the lesser of 3 percent of the excess of adjusted gross income (AGI) over the applicable amount, or 80 percent of the amount of itemized deductions otherwise allowable for the taxable year. For 1991, the applicable amount is $100,000 ($50,000 in the case of a married person filing a separate federal return). The applicable amount is to be increased each tax year to reflect inflation in the taxable years after 1991. For example, for 1995 the applicable amount is $114,700 ($57,350 in the case of a married person filing a separate return). This reduction in itemized deductions for certain high- income taxpayers applies for Iowa individual income tax purposes for the same tax years that the provision applies for federal income tax purposes. The following subrules clarify how the reduction in itemized deductions is to be determined on the Iowa individual income tax return: 303.11(1) Itemized deduction worksheet (Form 41-104). High-income taxpayers who are itemizing deductions on the Iowa income tax return and whose itemized deductions for federal income tax purposes were subject to reduction because their federal adjusted gross incomes exceeded certain amounts (the amounts for 1996 were $117,950 for all taxpayers except married taxpayers who filed separate federal returns and $58,975 for married individuals who filed separate federal returns) must complete Itemized Deduction Worksheet (Form 41-104) to determine the amount of federal itemized deductions that can be claimed on the Iowa income tax return. This worksheet must also be used to compute the itemized deductions allowable on the Iowa return for taxpayers who claimed the standard deduction on their federal individual income tax return, but are itemizing deductions for Iowa income tax purposes and whose Revenue deductions would have been subject to reduction, if they had itemized deductions on their federal income tax return. These taxpayers must complete the worksheet (Form 41-104) as if they had itemized deductions on their federal returns. Generally, the itemized deductions allowed on the federal income tax return for high-income taxpayers are also allowed for Iowa individual income tax purposes, except that the Iowa income tax that was allowable as a deduction on the federal Schedule A is not allowed as an Iowa itemized deduction. In addition, the deduction for medical expenses claimed as an itemized deduction on the federal income tax return should be reduced by the amount of health insurance premiums claimed as a deduction on line 18 of the IA 1040. The line references on Form 41-104 are to the federal 1040 and to the federal Schedule A for 1996 and to the IA 1040 for the 1996 tax year. Similar line references will apply on Form 41-104 and to IA 1040 for any later tax year when the taxpayer’s federal itemized deductions were subject to reduction because the taxpayer’s federal adjusted gross income exceeded the threshold amount for that year and the taxpayer itemized deductions on the Iowa income tax return. Note that if a taxpayer’s itemized deductions are less than the Iowa standard deduction amount, the taxpayer may elect to claim the Iowa standard deduction. Form 41-104 follows: 1. Enter the allowable federal itemized deductions as shown on line 34 of the 1040. 1. 2. Add the amounts on federal Schedule A, lines *4, 13, 19 plus any gambling losses including on line 27 and enter the total here. 2. 3. Subtract line 2 amount from line 1 amount. 3. 4. Add the amounts on federal Schedule A, lines *4, 9, 14, 18, 19, 26, and 27 and enter the total here. 4. 5. Subtract line 2 amount from line 4 amount. 5. 6. Divide line 3 by line 5 and enter percentage here. 6. % 7. Enter the amount of Iowa income tax that is included in line 5 of the federal Schedule A. 7. 8. Multiply line 7 by the percentage on line 6. 8. 9. Subtract line 8 from line 1. Enter this amount here and on line 39 of the IA 1040. 9. *The deduction for medical expenses from line 4 of federal Schedule A must be reduced by the amount of any health insurance premiums that were deducted on line 18 of Form IA 1040 in computing the taxpayer’s net income for the tax year. 303.11(2) Reserved.
