What this bill does

Plain-language analysis by the nonpartisan Legislative Reference Bureau

This bill repeals various tax credits that taxpayers may no longer earn because of sunset provisions related to each of those credits, repeals various obsolete tax provisions, and updates other tax provisions to reflect those changes. Current law allows taxpayers to carry forward certain unused nonrefundable tax credits to future years.

The bill repeals, among others, the following tax credits and other obsolete tax provisions:

1. The armed forces member credit.

2. The biodiesel fuel production credit.

3. The community development finance credit.

4. The dairy and livestock farm investment credit.

5. The development, development opportunity, development zone additional research, and enterprise development zones credits.
