Iowa Capital Gain Deduction - for certain business/farm assets ONLY (Line 23)
You must complete and include the applicable IA 100 with your return to claim the Iowa Capital Gain Deduction. Gains on the sale of stocks or bonds do not generally qualify for the capital gain deduction. Capital gains from the sale of investment property do not qualify for the capital gain deduction, even if sold to lineal descendants of the owners of the property. Non-farm rental property may qualify. In addition to the instructions and guidance found in the applicable IA 100, flowcharts to assist in determining if a gain qualifies are found in the Online Expanded Instructions.
