State income tax deadlines are approaching, but families saving for education expenses may still have time to reduce their 2024 taxable income.

Over 30 states, including the District of Columbia, offer a state income tax deduction or credit for 529 plan contributions. Most states have a contribution deadline of the end of the calendar year (December 31) to qualify for a 529 plan tax deduction on their tax return for that tax year. However, taxpayers in the states listed below have until April of the following year.
