Section 2  of the bill creates a new tax credit. The new tax credit allows taxpayers to claim a refundable tax credit, in addition to the child tax credit and the family affordability tax credit, in an amount determined by the amount and age of the taxpayer's children and the taxpayer's income. The total amount of the new tax credit is adjusted annually based on legislative council staff projections, such that the total amount of the new tax credit claimed in an income tax year is projected to be the same as the amount of revenue raised in sections 3 and 4.     Beginning January 1, 2027, the bill also repeals the downloaded software sales and use tax exemption so that all software that is available for repeated sale and license qualifies as tangible property and thus is subject to sales and use tax. The bill exempts from sales and use tax downloaded software governed by a negotiable license agreement or developed for use by a particular user.      Currently, 15% of the net revenue collected as sales and use tax is credited to the general fund, less 1.655% (allocation percentage), which is credited to the housing development grant fund. Beginning January 1, 2027, the bill reduces the allocation percentage to 1.625%.      The bill allows a county, a municipality, the regional transportation district, and the scientific and cultural facilities district (district) to maintain the taxable status of tangible personal property as downloaded computer software, as those terms are defined on December 31, 2026, unless the district elects to define computer software as tangible personal property, as those terms are defined on January 1, 2027, pursuant to an election that complies with the state constitution.(Note: Italicized words indicate new material added to the original summary; dashes through words indicate deletions from the original summary.)(Note: This summary applies to the reengrossed version of this bill as introduced in the second house.)
