What Are Eligible Automatic Contribution Arrangements (EACAs)?#

Eligible Automatic Contribution Arrangements (EACAs) are provisions within employer-sponsored qualified retirement plans (such as 401(k)s, 403(b)s, or SIMPLE IRAs) that automatically deduct a preset percentage of an employee’s paycheck for retirement savings—unless the employee explicitly opts out.

In other words, if an employee does not provide explicit instructions about pretax contributions to their retirement account, the employer will automatically enroll them at a default contribution rate. EACAs are designed to increase retirement plan participation by reducing the "inertia" that often prevents employees from saving—they turn "opt-in" into "opt-out."

How Do EACAs Work?#

EACAs follow a straightforward process to ensure employees are enrolled in retirement savings unless they choose otherwise:

Step 1: Employer Establishes the EACA#

The employer first sets up an EACA as part of their qualified retirement plan. This involves defining key parameters, such as the default contribution percentage, notice requirements, and investment options for default contributions.

Step 2: Employee Notification#

Before automatic enrollment begins, the employer must provide written notice to employees. This notice includes:

• The default contribution rate (e.g., 3% of pay).
• How to opt out or change the contribution rate.
• Information about the plan’s investment options (including the default investment, such as a target-date fund).
• Details about pretax vs. Roth contribution options (if available).

Step 3: Automatic Enrollment#

If the employee does not respond to the notice (i.e., does not opt out or adjust contributions), the employer automatically deducts the default percentage from their pretax pay and deposits it into their retirement account.

Step 4: Employee Flexibility#

Employees retain full control: They can opt out entirely, increase/decrease the contribution rate, or switch to Roth contributions (if offered) at any time.

Key Features of EACAs#

EACAs have several defining characteristics that set them apart from voluntary retirement plans:

1. Default Contribution Rate#

The default contribution rate is typically between 3% and 6% of an employee’s compensation, though employers may set higher rates. The IRS does not mandate a specific rate, but most plans use 3% as a starting point to balance savings incentives with affordability.

2. Opt-Out Mechanism#

EACAs are "opt-out," not "opt-in." Employees are automatically enrolled unless they actively choose to opt out. This reverses the traditional model, where employees must take action to start saving.

3. Notice Requirements#

Employers must provide a 30- to 90-day advance notice before automatic enrollment begins. This gives employees time to review the plan details and make informed decisions (opt out, adjust contributions, etc.).

4. Default Investment Options#

To protect employees, EACAs require default contributions to be invested in prudent, diversified options. Common defaults include target-date funds (which adjust asset allocation based on retirement age) or balanced funds, reducing the risk of poor investment choices.

5. Pretax Contributions (Typically)#

Most EACAs default to pretax contributions, meaning the amount is deducted from the employee’s paycheck before income taxes are applied. This lowers the employee’s taxable income in the short term, though taxes are owed when funds are withdrawn in retirement. Some plans may offer Roth (after-tax) options as well.

Benefits of EACAs for Employers and Employees#

For Employees#

• Overcomes Procrastination: Many people delay saving for retirement due to busy schedules or indecision. EACAs "force" saving by default, turning inaction into action.
• Compound Growth: Even small, consistent contributions (e.g., 3% of pay) can grow significantly over time thanks to compound interest.
• Tax Advantages: Pretax contributions reduce current taxable income, lowering annual tax bills.
• Flexibility: Employees can adjust contributions or opt out if their financial situation changes.

For Employers#

• Higher Participation Rates: EACAs dramatically increase retirement plan participation, which helps employers meet regulatory requirements (e.g., nondiscrimination testing) and demonstrates a commitment to employee financial wellness.
• Reduced Administrative Burden: Automatic enrollment streamlines the onboarding process, as employers don’t need to chase employees to join the plan.
• Tax Incentives: Employers may qualify for tax credits (e.g., under the SECURE Act) for adopting automatic enrollment features like EACAs.

Compliance and Regulatory Requirements#

EACAs are governed by federal regulations, primarily under the Employee Retirement Income Security Act (ERISA) and the Internal Revenue Code (IRC). Key compliance rules include:

• Notice Timing: Employers must provide written notice 30–90 days before automatic enrollment.
• Default Investment Safety: Default investments must be "qualified default investment alternatives" (QDIAs), such as target-date funds, to ensure prudent management.
• Opt-Out Rights: Employees must be allowed to opt out within a reasonable timeframe (typically 30 days) and receive a refund of contributions if they opt out promptly.
• Recordkeeping: Employers must maintain records of notices, employee elections, and contributions to comply with IRS and DOL audits.

Note: EACAs differ from Qualified Automatic Contribution Arrangements (QACAs), which have stricter requirements (e.g., higher default contribution rates and mandatory employer matching contributions). EACAs are more flexible for employers.

Key Takeaways#

• EACAs automatically enroll employees in retirement plans at a default contribution rate unless they opt out.
• They simplify retirement saving by reducing inertia, boosting participation rates.
• Key features include a default contribution rate (3–6%), opt-out mechanisms, advance notice, and prudent default investments.
• Benefits include compound growth for employees and higher plan participation for employers.
• Compliance with ERISA and IRS rules (e.g., notice timing, QDIAs) is critical for employers.
