# Colorado HB 21-1164 (2021A) — Total Program Mill Levy Tax Credit

For the 2020 property tax year, the existing statute corrects the total program mill levies for school districts that are not subject to constitutional property tax revenue restrictions but whose mill levies were erroneously reduced. Each school district that levies a higher number of mills as a result of the correction must grant a tax credit for the number of mills by which the levy is increased.The act requires the department of education to adopt a correction schedule to begin phasing out the tax credits in the 2021 property tax year. The correction schedule must apply consistently to each affected school district; must require each district's tax credit to phase out as quickly as possible, but by no more than one mill per year; and must ensure that the tax credits are fully phased out in 19 years.The act specifies that, until the general assembly determines that stabilizing the state budget no longer requires a reduction in the appropriation for the state share of total program, the general assembly shall annually ensure that the savings to the state share that occurs as a result of the decrease in the temporary property tax credits is appropriated to fund a portion of the state share of total program.(Note: This summary applies to this bill as enacted.)
