This legislation aims to expand retirement savings opportunities for younger workers by lowering the minimum age for participation in certain plans. It amends the Employee Retirement Income Security Act of 1974 (ERISA) and the Internal Revenue Code of 1986 to reduce the eligibility age for pension plans and qualified trusts from 21 to 18 years old . This change allows individuals to begin contributing to their retirement savings earlier in their careers. Specifically, the bill modifies ERISA Section 202(c)(1) and Internal Revenue Code Section 401(k)(2)(D) to incorporate the new age requirement, while also retaining provisions for employees who complete two consecutive 12-month periods with at least 500 hours of service. A special rule is introduced for ERISA reporting, stipulating that employees participating solely due to the new age 18 rule are not counted as participants for five years for certain independent qualified public accountant opinions. These amendments are set to take effect for plan years beginning on or after one year following the bill's enactment.
