Retirement savings are a crucial part of financial planning, and recent legislative changes are making it easier for employees to build their nest eggs. With the passage of the SECURE 2.0 Act, new automatic enrollment requirements for 401(k) and 403(b) plans will take effect in 2025. These updates are designed to increase participation in employer-sponsored retirement plans, ensuring that more employees are actively saving for their future.

If you own a business or manage employee benefits, understanding these changes is essential for compliance and effective financial planning. Below, we break down the key details of the new automatic enrollment rules and what they mean for both employers and employees.


What Are the New Automatic Enrollment Requirements?

Starting in 2025, most new 401(k) and 403(b) plans will be required to automatically enroll eligible employees. Here’s what you need to know:

1. Automatic Enrollment at 3% to 10%

  • Employers must automatically enroll eligible employees at a contribution rate of at least 3% but no more than 10% of their pre-tax earnings.
  • Employees will have the option to opt out or adjust their contribution percentage.

2. Annual Auto-Escalation of Contributions

  • Each year, the employee’s contribution rate must increase by 1% until it reaches at least 10%, but no more than 15% (unless they choose a different percentage).

3. Applicability to New Plans

  • These requirements only apply to new plans established after December 31, 2024.
  • Plans in place before this date are grandfathered in and do not need to implement automatic enrollment.

4. Exemptions

Some employers and plans are exempt from the new requirements, including:

  • Businesses with 10 or fewer employees
  • New businesses (less than 3 years old)
  • Government and church plans

Why Is This Change Important?

1. Boosting Retirement Savings

Studies show that automatic enrollment significantly increases participation in retirement plans. By making enrollment the default option, more employees will start saving early, leading to greater financial security in retirement.

2. Employer Benefits

Employers who comply with these changes may benefit from:

  • Increased employee retention and satisfaction
  • Tax credits for starting new retirement plans
  • A more financially secure workforce, reducing stress-related productivity issues

3. Compliance and Avoiding Penalties

Failing to comply with these new rules can lead to IRS penalties and legal complications. Employers should take steps now to update their retirement plan policies and ensure compliance by 2025.


How Employers Can Prepare for the Change

  1. Review Your Current Retirement Plan

    • If you already offer a 401(k) or 403(b), determine whether your plan is grandfathered in or if changes are needed.
  2. Update Plan Documentation and Policies

    • Work with your payroll and benefits provider to update your automatic enrollment features and employee communication strategies.
  3. Educate Employees

    • Make sure employees understand how automatic enrollment works, their contribution options, and how to opt out if they choose.
  4. Consult a Tax Professional

    • These new requirements could have tax implications. Speak with a tax expert to understand how compliance affects your business tax filings and potential deductions.
