An act relating to the expansion of existing income tax credits

H 483 expands Vermont's tax credit programs to provide greater financial support for low- and middle-income residents. It extends the Vermont Child Tax Credit to cover children six years old or younger (previously age five), increases the Earned Income Tax Credit for individuals without qualifying children to 100% of the federal credit amount, and raises income thresholds for exempting Social Security and retirement income from state taxes. These changes directly affect families with young children, low-income workers without children, and retirees with modest incomes. The bill modifies specific Vermont tax code sections to implement these eligibility expansions and benefit increases.
