Instruction Year

Enter the total of other allowable adjustments as described below. Include an explanation for each adjustment.

Do not include any deduction for the small business health insurance tax credit that was not allowed as a deduction on the federal return.

a. Accrual method

Taxpayers who had capital gains in 2017 that were reported on the installment method for federal tax purposes and the entire gain was reported for Iowa in a prior year do not have to report installments.

b. Active duty military pay

Members of the armed forces, armed forces military reserve and the national guard in an active duty status can exclude pay received from the federal government for military service performed, to the extent it was included in line 15, Gross Income.

c. Alternative motor vehicle deduction

Alternative motor vehicle deduction of $2,000 for those completing federal form 8910 (Alternative Motor Vehicle Credit)

The Internal Revenue Service certifies whether or not a vehicle qualifies. A complete list of vehicle models that have been certified for the Alternative Motor Vehicle Credit can be seen on the IRS website.

d. Capital gain from installment sales reported on the 2001 Iowa return using the accrual method

The installment method for reporting capital gain for accrual accounting taxpayers is adopted for Iowa individual income tax purposes for tax years beginning on or after January 1, 2002. However, if you used the accrual method of accounting and reported the entire capital gain on the 2001 Iowa return which was reported on the installment method for federal tax purposes, deduct the amount reported of any additional installments from that capital gain on this line.

e. Capital or ordinary gain from involuntary conversion related to eminent domain

An exclusion of both capital gain and ordinary gain is available for individual income taxpayers relating to capital or ordinary gain income realized by a taxpayer as a result of the involuntary conversion of property due to eminent domain. Eminent domain relates to the authority of certain government agencies or instrumentalities of government to condemn private property for any public improvement, public purpose, or other public use.

If there is no ordinary or capital gain recognized for tax purposes because the converted property is replaced with property that is similar to, or related in use to, the converted property, there is no exclusion allowed for Iowa tax purposes until the remaining gain is recognized for federal tax purposes or until the time of disposition of the replacement property. Any exclusion allowed for Iowa tax purposes does not alter the basis of the property as established for federal tax purposes, so the basis will remain the same for both federal and Iowa tax purposes.

f. Claim of Right Deduction

If income was repaid in the 2017 tax year and was reported and taxed on a prior Iowa return, that income may be deducted on the 2017 tax return. However, it may be to your advantage to take a credit on line 62. You may take either the deduction on line 24 or take a credit on line 62, but not both.

Example of Claim of Right Deduction: A taxpayer reported $7,000 in unemployment benefits on the 2014 Iowa return. In early 2017 the taxpayer was notified that $4,000 of the unemployment benefits had to be repaid. The benefits were repaid by the end of 2017. The taxpayer may claim a $4,000 income adjustment on line 24 of the 2017 Iowa return.

g. College Savings Iowa or Iowa Advisor 529 Education Savings Plans

If you or your spouse participate in the College Savings Iowa 529 Plan (Iowa Educational Savings Plan Trust) or the Iowa Advisor 529 Plan, each may deduct an amount contributed not to exceed $3,239 per beneficiary. These are Iowa Section 529 Plans.

You must be the "participant" in the Iowa 529 plan in order to deduct your contributions. If you are not the "participant" in the Iowa 529 plan, you may not deduct your contributions to that plan.


Adam and Tara have 2 children; Charlie and Ruth.  Adam opens two 529 accounts – one for Charlie and one for Ruth.  Tara also opens two 529 accounts for both Charlie and Ruth.  Both Adam and Tara can take up to $3,239 per child’s account.  Adam and Tara each are eligible for a deduction of up to $6,478.  Adam and Tara’s total potential deduction amount is $12,956.

Only contributions to these two Iowa 529 plans qualify for a deduction on the Iowa return; however, a rollover from another state's 529 plan to one of the Iowa plans qualifies toward the deduction for Iowa income tax.

Be sure you have properly shown these contributions as a deduction for one of these plans.  Most computer software programs will ask for this information and correctly indicate the appropriate reason for the deduction.

Beginning with tax year 2015, individuals making a contribution on or before the Iowa income tax return filing deadline (April 30 for calendar year tax filers), excluding extensions, can elect to have that contribution treated as though it was made on the last day of the preceding calendar year, which allows them to claim the income tax deduction for the most recently completed tax year.

Prior to tax year 2015, contributions had to be made during the calendar year in order to be deductible on the Iowa return for that year.

h. Disability income exclusion

You may exclude from Iowa tax a portion of the disability pay you received in 2017 if you meet ALL of the following conditions:You received disability pay, and

  • You received disability pay, and
  • You were not yet 65 when your tax year ended, and
  • You retired on disability and were totally and permanently disabled when you retired, and
