529 Expansion and Modernization Act of 2018 This bill allows tax-exempt distributions from qualified tuition programs (known as 529 plans) to be used for: apprenticeship programs, early education expenses for children under the age of 5, career and technical education programs, and industry intermediary education programs. The bill also allows employers to make contributions to an employee's 529 plan as a fringe benefit that is excluded from the gross income of the employee. The contributions per employee may not exceed $500 per year (adjusted for inflation after 2019) and must be made in connection with a payroll deduction contribution program.
