To amend the Internal Revenue Code of 1986 to establish an exception for multiemployer plan participants to the requirements for automatic enrollment.

This bill exempts multiemployer pension plans from automatic enrollment requirements under the Internal Revenue Code. Specifically, it amends Section 414A(c)(3) to explicitly exclude multiemployer plans (defined under Section 414(f)) from rules requiring automatic enrollment in retirement plans. This change directly affects workers enrolled in union-sponsored multiemployer pension plans, allowing these plans to avoid automatic enrollment obligations. The amendment applies to taxable years beginning after December 31, 2024.
