Column A should be used to report additions to federal taxable income and Column B should be used to report subtractions from federal taxable income. Report all amounts as a positive number.

Line 1: Interest

Column A: Enter interest from state and municipal securities, to the extent not already included in federal taxable interest on the IA 1040, line 2, unless specifically exempt from Iowa tax.

Amounts received from the cancellation of a participation agreement or other non-qualifying withdrawal to the extent the amount was previously deducted on the IA 1040. Qualifying withdrawals may include up to $10,000 per beneficiary per year for tuition expenses of attending an accredited elementary or secondary (K-12) school in Iowa or an out-of-state elementary or secondary school that educates a beneficiary who is a child “requiring special education” under Iowa Code section 256B.2. The $10,000 per-beneficiary cap applies even if the beneficiary receives money from multiple College Savings Iowa or Iowa Advisor 529 Plan accounts. The $10,000 annual cap does not apply to withdrawals used to pay qualified education expenses related to higher education. Qualifying withdrawals include withdrawals for certain expenses related to participation in an apprenticeship program and withdrawals, up to $10,000, used to pay either principal or interest on a qualified education loan on behalf of a beneficiary or a beneficiary’s sibling. If you withdrew funds from a 529 Plan to pay qualified higher education expenses and you received a refund of those funds, the refund amount is considered a qualifying withdrawal if it is recontributed to the same Iowa 529 Plan account from which it was withdrawn within sixty (60) of the date of the refund.

Non-qualified withdrawals required to be added back here are assessed a penalty equal to 10% of the amount of the withdrawal, unless the non-qualifying withdrawal was made by reason of the death of the account holder or certain other circumstances. If an account holder makes a non-qualifying withdrawal, they are not permitted to claim a deduction for any future contribution to any First-time Homebuyer Savings Account. All withdrawals (qualifying and non-qualifying) from your First-time Homebuyer Savings Account must be reported to the Department on the Iowa First-time Homebuyer Savings Account Withdrawal Form within 90 days of the date of withdrawal.

n. Net Premium Tax Credit

The Net Premium Tax Credit from the 2022 federal 1040, Schedule 3, line 9 will be reported as Other Income on this line. The Net Premium Tax Credit is reportable income to the extent these credits were a reimbursement for health insurance premiums deducted from Iowa income in a prior year.

If the deduction is taken on the IA 1040 Schedule A (for tax years prior to 2023), then the federal tax guidance should be followed when addressing the complications due to the impact of the Federal Excess Advance Premium Tax Credit repayment and the Net Premium Tax Credit.

However, if the deduction is taken on IA 1040, line 18 (for tax years prior to 2023), then the IA 1040, Schedule 1, Line 11, must reflect the impact of the Federal Excess Advance Premium Tax Credit repayment and the Net Premium Tax Credit. The Iowa expanded instructions for this line and IA 1040, Schedule 1, line 15 set forth the Department’s guidance for the correct reporting of these amounts.

Line 12: Total modifications to federal total income

Add lines 1 through 11.

Line 13: Net modifications to federal total income

Subtract line 12, column B from line 12, column A.

Line 14: Federal income tax refund or overpayment received in 2023

To find out the amount of your federal refund, contact the IRS at 1-800-829-1040 or www.irs.gov. If you received a federal tax refund in 2023, you must report the amount on IA 1040 Schedule 1, line 14. It must be reported even if you used the standard deduction on the prior year’s Iowa return. The federal refund must be included on this line because you benefited from being able to deduct federal taxes on the prior year’s Iowa return, which reduced your Iowa taxable income for that year. The amount reported on the IA 1040 Schedule 1, line 14 should not exceed the total amount of any federal tax deduction taken on the prior year(s) Iowa return. The total overpayment is reported on Schedule 1, line 14.

Any portion of the federal refund received due to the fuel tax credit must be reported on the Iowa return. Include any amount received in 2023 due to excess FICA payments if the amount was claimed as a federal tax payment on the 2022 Iowa return. Report any federal income tax refund received in 2023 for tax year 2022 or any other years that were amended or filed late.

Do not include the portion of the federal refund attributable to the following :

  • Do not include federal refundable credits such as earned income tax credit, additional child tax credit, refundable education credit, net premium tax credit, or recovery rebate credit.
  • You are filing an Iowa return for 2023 for the first time. A refund of federal tax received in 2023 is not reported if the tax was not deducted from Iowa income in a prior year.
  • The refund you received was from a year in which you did not take a deduction for the payment of federal tax because your income was less than the minimum amount for paying Iowa tax or your tax for that year was calculated using the alternate tax computation.
  • You were a nonresident for the tax year of the refund and were not required to file an Iowa return for that year.

Married Separate Filers:
If the refund received in 2023 was from a jointly-filed federal return, it must be divided between the spouses in the ratio of the spouses’ Iowa net incomes in the year for which the refund was issued.

Line 15: Health Insurance Deduction

For taxpayers who are 65 years of age or older and whose Iowa taxable income is less than $100,000, enter 100% of the amount paid for health and dental insurance premiums paid with post-tax funds. Typically, employer health insurance premiums are made on a pre-tax-basis when they are deducted from wages. Do not include any amount of health insurance that was used as a deduction in the computation of federal taxable income, this includes amounts reported on federal 1040, Schedule A, line 1, and federal 1040, Schedule 1, Part II, line 17. 

Enter 100% of the amount paid for:

  • health insurance premiums paid with post-tax dollars
  • supplemental health insurance, such as:
    • Medicare B supplemental medical insurance
    • Medicare D voluntary prescription drug insurance
  • dental insurance premiums paid with post-tax dollars
  • long-term nursing home coverage premiums paid with post-tax dollars regardless of age

Do NOT include:

  • “Medicare tax withheld” on your W-2
  • premiums paid with pre-tax dollars
  • premiums which are later reimbursed, in the same tax year

The $100,000 taxable income limitation is calculated without regard to filing status, meaning that a single taxpayer, a married taxpayer filing separately, and a couple that files married filing jointly will all have a $100,000 taxable income limitation. 

To calculate taxable income for purposes of this deduction, add back:

  • Pensions or other retirement income received from a source that is not taxable in Iowa;
  • Federal itemized or standard deduction to the extent it does not exceed federal adjusted gross income;
  • Federal personal exemption deduction ($0 for 2023);
  • Federal qualified business income deduction;
  • Reportable Social Security income. See Reportable Social Security Benefits.

The deduction must be reduced by the amount of any premium reimbursement from Health Reimbursement Arrangements (HRAs).

Federal Health Insurance Credits

Any Excess Advance Premium Tax Credit repayment from the 2022 federal form 1040, Schedule 2, line 2 will be entered on IA 1040, Schedule 1, line 15 in the year paid (For tax years 2023 and later). Any repayment calculated on your 2023 federal return cannot be included on the 2023 IA 1040, Schedule 1, line 15.

The Net Premium Tax Credit from the 2023 federal form 1040, Schedule 3, line 9 will be reported as Other Income on the 2024 IA 1040, Schedule 1, line 11. The federal Net Premium Tax Credit is reportable income to the extent this credit was a reimbursement for health insurance premiums deducted from Iowa income in a prior year.

If the deduction is taken on the IA 1040, Schedule A (For tax years prior to 2023), then the federal tax guidance should be followed when addressing the complications due to the impact of the Federal Excess Advance Premium Tax Credit repayment and the Net Premium Tax Credit.

Married Separate Filers:
If both spouses have self-employment income, the deduction for self-employed health insurance must be allocated between the spouses in the ratio of each spouse’s self-employment income to the total self-employment income of both spouses. If health insurance premiums are paid directly by one spouse, that spouse will claim the entire deduction.

If both spouses paid through a joint checking account, the deduction is allocated between the spouses in the ratio of each spouse’s Iowa taxable income to the total Iowa taxable income of both spouses. For this Iowa taxable income calculation, do not include the health insurance deduction. If one spouse is employed and has post-tax health insurance premiums paid through wages, that spouse will claim the entire deduction. If both spouses pay post-tax health insurance premiums through their wages, each spouse will claim what each spouse paid.

Line 16: Capital Gains Deduction

You must complete and include the applicable IA 100 with your return to claim the Iowa capital gain deduction. In addition to the instructions and guidance found in the applicable IA 100, flowcharts to assist in determining if a gain qualifies can be found on the Department’s website.

Married Separate Filers:
Divide the capital gain deduction based on ownership of the asset.

  • Jointly held: Divide equally between spouses.
  • If other than jointly held: Divide between spouses based on percentage of ownership.

Each spouse must file a separate form of the applicable IA 100.

Line 17: Iowa Net Operating Loss (NOL) prior to 1/1/23

Enter the Iowa NOL carried forward from a tax year prior to January 1, 2023 from IA 124, Part II, line 5. Include the IA 124 with your return.

Line 18: Federal Tax Paid for Prior Years

Enter the amount of additional federal income tax paid during 2023 for tax year 2022 and any prior tax years. The amount of additional federal income tax paid is deductible only if Iowa income tax returns were required to be filed for the year for which the additional federal income tax was paid. Include only the actual federal income tax payments made in 2023, but do not include penalties and interest. 

For taxpayers whose reporting method was to report the amount of self-employment, household tax,  or other federal taxes in the following year, reduce the amount of federal tax paid reported on line 18 by the following:

  • Excess advance premium tax credit repayment reported on the 2022 federal 1040, Schedule 2, line 2
  • Federal self-employment tax reported on the 2022 federal 1040, Schedule 2, line 4
  • Total additional Social Security and Medicare tax reported on the 2022 federal 1040, Schedule 2, line 7

  • Repayment of first-time homebuyer credit reported on the 2022 federal 1040, Schedule 2, line 10
  • Additional Medicare tax from federal form 8959 reported on the 2022 federal 1040, Schedule 2, line 11
  • Uncollected social security and Medicare or RRTA tax on tips or group-term life insurance from Form W-2, box 12, reported on the 2022 federal 1040, Schedule 2, line 13
  • Interest on tax due on installment income from the sale of certain residential lots and timeshares reported on the 2022 federal 1040, Schedule 2, line 1
  • Interest on the deferred tax on gain from certain installment sales with a sales price over $150,000 reported on the 2022 federal 1040, Schedule 2, line 15
  • Recapture of low-income housing credit reported on the 2022 federal 1040, Schedule 2, line 16
  • Other additional federal taxes reported on the 2022 federal 1040, Schedule 2, line 18

Note: If line 18 results in a negative amount, due to the adjustments reported above, report this amount as a positive figure and add this amount to the amount reported on Schedule 1, line 14.

Married Separate Filers:
The additional federal tax paid must be divided between the spouses in the ratio of the spouses’ Iowa net incomes for the prior years for which they paid additional federal income tax.

Line 19: Other Adjustments

Enter the total of other allowable adjustments as listed below. Include an explanation for each adjustment on a separate form or schedule. Column A should be used to report additions to federal taxable income and Column B should be used to report subtractions, deductions and exclusions from federal taxable income. Report all amounts as a positive number.

a. Accrual method

Taxpayers who had capital gains in 2023 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. RESERVED FOR FUTURE USE

c. RESERVED FOR FUTURE USE

d. RESERVED FOR FUTURE USE

e. RESERVED FOR FUTURE USE

f. Claim of Right Deduction

If income was repaid in the 2023 tax year and was reported and taxed on a prior Iowa return, that income may be deducted on the 2023 tax return. However, it may be to your advantage to take a credit on line 26. You may take either the deduction on Schedule 1, line 19 or take a credit on line 26, but not both.

Example: A taxpayer reported $7,000 in unemployment benefits on the 2022 Iowa return. The taxpayer’s 2022 AGI exceeded $150,000 without including the unemployment income. The taxpayer did not qualify for the unemployment exclusion. In early 2023 the taxpayer was notified that $4,000 of the unemployment benefits had to be repaid. The benefits were repaid by the end of 2023. The taxpayer may claim a $4,000 income adjustment on the 2023 IA 1040, Schedule 1, line 19.

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 $3,785 per beneficiary. This deduction is only available for contributions to Iowa 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.

Example: 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 one for Charlie and one for Ruth. Both Adam and Tara can take up to $3,785 per child’s account. Adam and Tara each are eligible for a deduction of up to $7,570. Adam and Tara’s total potential deduction amount is $15,140.

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. If you received a refund of any qualified higher education expenses from an eligible educational institution and recontributed the refund amount consistent with Iowa Code section 422.7(22)(c)(1)(f)(i), you may not deduct the recontribution amount when calculating your Iowa taxable income and the recontribution amount will not be considered when determining whether you have met the annual deduction cap.

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.
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.

h. Disability income exclusion

You may exclude from Iowa taxable income a portion of the disability pay you received in 2023 if you meet ALL of the following conditions:

  • 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
  • On January 1, 2023, you had not yet reached the age when your employer's retirement program would have required you to retire.

If you meet all of these conditions, include form IA 2440. You MUST complete form IA 2440 to take this exclusion. A doctor's statement must accompany each year's return attesting to the taxpayer's complete and permanent disability.

j. First-Time Homebuyer Savings Account qualifying contributions

You may deduct up to $2,181 ($4,363 for married filing jointly) in qualifying Iowa First-Time Homebuyer Savings Account contributions made during the tax year. This deduction limitation is based on the account holder, so even though you may have contributed to multiple accounts for more than one beneficiary, your total deduction may not exceed $2,181 ($4,363 for married filing jointly).

The Account Holder and Designated Beneficiary Form must be submitted to the Department by the due date of the Iowa individual income tax return, April 30 for calendar year filers, of the calendar year following the year in which you opened the account to the address on that form.

The Account Holder and Designated Beneficiary Form must be submitted to the Department separately from your 2023 Iowa income tax return.

Taxpayers are also required to complete an Iowa Department of Revenue annual report form and include it with their Iowa income tax return.

Complete and send a First-time Homebuyer Withdrawal Form, 41-163 to the Iowa Department of Revenue when money is withdrawn. Note: this form must be submitted to the Department within ninety (90) days of the date of any withdrawal of funds in any amount from the First-Time Homebuyer Savings Account.
