Key takeaways
An EACA is a retirement plan feature that automatically enrolls employees at a uniform default contribution rate unless they opt out or change their election.
Employees in an EACA may have a 30- to 90-day window to withdraw their automatic contributions without the typical 10% early withdrawal penalty.
Employers using an EACA for all eligible participants receive an additional six months to correct failed nondiscrimination tests without incurring an excise tax.
What is an Eligible Automatic Contribution Arrangement (EACA)?
An Eligible Automatic Contribution Arrangement (EACA) is a feature within a retirement plan like a 401(k) that allows employers to automatically enroll employees at a set default contribution rate. It was established under the Pension Protection Act of 2006 to help boost participation in workplace retirement plans by removing the need for employees to actively sign up.
The idea is simple: instead of waiting for employees to opt in, the employer sets a default percentage of compensation that's automatically contributed to the plan on the employee's behalf. This rate must be uniform, meaning the same default percentage applies to all employees covered by the arrangement.
Importantly, employees aren't locked in. After receiving the required notice from their employer outlining the default rate, their investment options, and their rights, they can choose to adjust their contribution rate, change their investments, or opt out entirely.
One other detail worth noting: employees are 100% vested in their automatic enrollment contributions from day one, meaning there's no waiting period before that money is fully theirs.
How an EACA Works
EACAs are meant to simplify the onboarding process for retirement savings. However, there are strict compliance rules that employers must follow to maintain this status.
The permissive withdrawal window
One of the most distinct features of an EACA is the permissive withdrawal. This rule allows employees who were automatically enrolled to change their minds. Within a window of 30 to 90 days after the first automatic contribution is withheld from their paycheck, the employee can request to withdraw their contributions and any related earnings.
Crucially, these permissive withdrawals are not subject to the 10% early withdrawal penalty that usually applies to distributions taken before age 59½.
Savers who choose to withdraw these funds often reallocate them to liquid accounts, such as high-yield savings accounts, to maintain flexibility while keeping cash accessible.
Uniformity and notice requirements
For a plan to qualify as an EACA, it must meet two core requirements.
The first is uniformity. The default contribution rate must be the same percentage for all employees covered by the arrangement. An employer can't set a higher rate for one group and a lower rate for another.
The second is notice. Employers must provide written notice to all covered employees before automatic contributions begin. This notice needs to clearly explain:
The default contribution percentage
The employee’s right to change that percentage or opt out entirely
How the contributions will be invested in the absence of an employee's choice (typically a Qualified Default Investment Alternative, or QDIA)
EACA vs. QACA: Key Differences
While both EACAs and QACAs (Qualified Automatic Contribution Arrangements) involve automatic enrollment, they serve different compliance purposes.
The QACA is a "Safe Harbor" plan, meaning the employer is exempt from annual nondiscrimination testing because they have committed to specific matching or nonelective contributions.
An EACA does not provide this exemption, but it does offer more flexibility in plan design and employer cost.
Here’s a quick breakdown of the differences:
Feature | EACA | QACA |
Employer match | Optional | Required (has specific formulas) |
Vesting | Immediate (for employee funds) | Can have a two-year cliff for employer funds |
Safe harbor status | No (does not automatically pass tests) | Yes (automatically passes ADP/ACP tests) |
Withdrawal window | 90-day permissive withdrawal optional | Permissive withdrawal optional |
Corrective action | Six-month extension for testing | N/A (testing is bypassed) |
Benefits for savers and employers
The EACA structure offers tangible advantages for both sides of the employment relationship.
For savers, it removes the "friction" of starting a retirement account. Many employees intend to save but fail to fill out the paperwork. Or, they may plan to do so “next year,” but forget when the time comes around. An EACA ensures they begin building a nest egg from their first paycheck.
For employers, there are benefits, too. If an EACA covers all eligible employees, the business gets an extension to correct failed Actual Deferral Percentage (ADP) or Actual Contribution Percentage (ACP) tests. Normally, employers must distribute excess contributions by March 15 to avoid a 10% excise tax. Under an EACA, this deadline is extended to six months after the end of the plan year.
Bottom line
An Eligible Automatic Contribution Arrangement (EACA) can help increase retirement plan participation through automatic enrollment.
While it provides a flexible "out" for employees via the 90-day permissive withdrawal rule, the primary goal is to establish a consistent habit of saving. For employers, the primary draw is the administrative grace period for nondiscrimination testing.
Understanding these arrangements is a key step in financial education, ensuring you know exactly where your paycheck is going and what rights you have to manage those funds. And with a retirement strategy in place, many savers balance their portfolio by building an emergency fund and liquid cash through high-yield savings for well-rounded financial stability.
Frequently asked questions
What is the main difference between an EACA and a QACA?
The primary difference between an EACA and a QACA lies in "Safe Harbor" status and employer contributions.
A QACA is a Safe Harbor plan that requires the employer to make specific matching or nonelective contributions in exchange for an exemption from annual nondiscrimination testing.
An EACA, meanwhile, doesn’t require employer contributions and doesn't exempt the plan from testing. That said, it does grant a six-month extension for correcting failed tests.
Can I withdraw my money from an EACA if I was enrolled automatically?
Yes, you can withdraw your funds from an EACA if you were enrolled automatically. You typically have a window of 30 to 90 days from the date of your first automatic contribution to request a refund of your deferrals plus any earnings. These specific withdrawals are exempt from the 10% early withdrawal penalty, though the amount is still considered taxable income for the year it is received.
Are employer matches required in an EACA?
No, employer matching is not a requirement for an Eligible Automatic Contribution Arrangement. While many employers choose to offer a match to incentivize saving, an EACA can function solely as a mechanism for automatic employee deferrals.
How does an EACA benefit 401(k) plan testing?
An EACA provides a significant administrative advantage by extending the deadline for corrective distributions. If a 401(k) plan fails its annual ADP or ACP nondiscrimination tests, the employer normally has 2.5 months to fix the issue or pay a 10% excise tax. If the plan is an EACA covering all eligible employees, this deadline is extended to six months, giving the company more time to avoid penalties.
