Property tax rates and levies. Allows the county auditor to reduce a taxing unit's assessed value used to set property tax rates for the following year to enable the unit to absorb the effects of reduced property tax collections expected to result from successful assessed value appeals. Limits the amount of the reduction. For property taxes first due and payable in 2006, sets a civil taxing unit's maximum property tax levy at the amount that would have applied for taxes payable in 2005 if the 2004 change had not been enacted that eliminated unused maximum levy capacity from the determination of the next year's maximum levy. Reverses that change for future years.
