Increasing the eligible credit amount for the earned income tax credit.

HB 2620 increases Kansas' earned income tax credit (EITC) by raising the state credit percentage from 17% to 18% of the federal EITC amount for tax years 2010-2012, then maintaining 17% for all subsequent years. It directly affects low-to-moderate-income Kansas residents who qualify for the federal EITC and claim it on their state tax returns. The bill modifies how the state credit is calculated (based on the federal credit amount) and ensures any excess credit beyond state tax liability is refunded to the taxpayer. This change updates Kansas law to align with the federal credit percentage, effective upon publication in the statute book.
