The Internal Revenue Service has published a final rule that applies to employers that want to set up qualified automatic contribution arrangement programs.
Employers that sponsor 401(k) plans can use QACAs to avoid running afoul of antidiscrimination rules.
When employers set up QACA programs, employees must take active steps to opt out of a 401(k) plan to avoid having to contribute to the plan.
The final QACA regulations take effect today and are based on a draft published in November 2007.
