For 4 income tax years beginning in 2022, the act creates a refundable income tax credit for an early childhood educator who: Has an adjusted gross income that is less than or equal to $75,000 for an individual filing a single return or $150,000 for an individual filing a joint return; Holds an early childhood professional credential for at least part of the income tax year; and For at least 6 months of the income tax year, is either the licensee or employee of an "eligible program", as defined by the act. The amount of the credit is dependent on the eligible early childhood educator's credentialing level, with higher levels receiving a larger credit, and is annually adjusted for inflation. The department of human services, or a successor department, is required to annually provide the department of revenue with an electronic report of each individual who held an early childhood professional credential during the previous calendar year for which the credit is allowed. (Note: This summary applies to this bill as enacted.)
