An Act relative to expanding 529 deductions

This bill amends Massachusetts tax law to expand the types of 529 education savings plans eligible for state tax deductions. It removes the restriction that previously limited deductions to plans "established by the commonwealth or an instrumentality of the commonwealth," instead allowing deductions for any plan authorized under federal U.S.C. § 529. This change directly affects Massachusetts residents who contribute to 529 plans, as it now includes federally authorized plans (not just state-run ones) in the deduction eligibility. The key mechanism is a specific update to Chapter 62, Section 3 of the General Laws, broadening the definition of qualifying plans under state tax code.
