Provides for voluntary contributions by taxpayers on gross income tax returns to State aid for public schools.

S 1778 allows New Jersey taxpayers to voluntarily add a portion of their state income tax refund to a dedicated "School Aid Contribution Fund" when filing their tax returns. This fund supplements existing state school funding under the School Funding Reform Act of 2008, rather than replacing it. Taxpayers simply indicate their contribution choice on their tax form, and collected funds are annually allocated by the Legislature to public school districts. The bill ensures these voluntary contributions cannot reduce the regular state appropriation for school aid each year. It applies to all New Jersey taxpayers filing gross income tax returns.
