The 2006 Legislative Summary is available online only.

The phase-out of tax on Social Security benefits does not begin until January 1, 2007. Therefore, the phase-out is not calculated on the 2006 IA 1040.

The increase in filing thresholds for taxpayers 65 and older does not begin until January 1, 2007. Therefore, the change does not apply to the 2006 IA 1040.

The alternate tax calculation for taxpayers 65 or older does not begin until January 1, 2007. Therefore, it is not available on the 2006 IA 1040.

Capital gains deduction: Beginning January 1, 2006, Iowa follows Federal holding period rules. The material participation requirements have not changed.

In addition to the legislative change, the department has revised its position on another aspect of the capital gains deduction. Previously, the department had taken the position that in order to claim a capital gain exclusion for individual income tax, a taxpayer must be in a net capital gain position on the federal return. If a taxpayer was in a net capital gain position, then the capital gain exclusion could exceed the capital gains reported on the federal return if the qualifying gain was offset by non-qualifying capital losses (such as stock sales). After a review by the Attorney General's office, the department has changed its position on this issue and will allow a capital gain exclusion from qualifying gains even if the taxpayer was in a capital loss position on the federal return.

Other legislative changes are incorporated in the Line Changes information below.
