Section 101: Mandatory Automatic Enrollment
Starting with plan years beginning after December 31, 2024, the SECURE 2.0 Act mandates that all new 401(k) and 403(b) retirement plans created after the law’s enactment must include an automatic enrollment feature. This provision aims to boost employee participation by automatically enrolling eligible workers into their employer’s retirement plan unless they choose to opt out. The requirement reflects a significant policy shift toward encouraging retirement savings through default enrollment mechanisms, which have been shown to increase participation rates and help close the savings gap among workers.
Affected Plan Types
- New 401(k) retirement plans established after the enactment date, subject to automatic enrollment rules.
- New 403(b) retirement plans created following the law’s effective date, also required to implement automatic enrollment.
- Exemption for small businesses with fewer than 10 employees, which are not required to implement automatic enrollment under this provision.
- Exemption for newly established businesses less than three years old, which are temporarily exempt from the automatic enrollment mandate.
Effective Dates
The automatic enrollment requirement takes effect starting January 1, 2025, applying to all eligible plans beginning plan years after this date.
This rule applies specifically to retirement plans established on or after December 29, 2022, ensuring that newly created plans incorporate automatic enrollment provisions as part of their design.
Neutral Impact Analysis
The mandatory shift to automatic enrollment is anticipated to raise overall participation rates within the nonprofit and educational sectors by reducing barriers to entry for employees. Employers will face new administrative responsibilities, including setting default contribution rates—typically a minimum of 3% of pay—and establishing automatic escalation features that increase contributions by 1% annually until reaching 10% or 15%. While these changes support long-term retirement savings growth, they also require employers to update plan administration and communication processes to comply with the new standards.
