Increase the earned income tax credit

LB 710 increases Nebraska's earned income tax credit (EITC) for low- and moderate-income residents who qualify for the federal EITC. It raises the state refundable credit rate from 10% to 20% of the federal EITC amount for tax years beginning January 1, 2025, and adjusts income thresholds. The credit phases out for individuals with federal adjusted gross income above $22,000, reducing by 10% for each $1,000 earned over that amount. This change directly benefits eligible Nebraska residents who currently receive the federal EITC, providing them with additional state tax relief.
