What is a Safe Harbor 401k

A Safe Harbor 401(k) plan is a type of retirement savings plan offered by employers that provides certain protections against lawsuits by employees. These plans are designed to meet specific requirements set forth by the Internal Revenue Service (IRS) and are often used by employers who want to offer a retirement savings plan to their employees but are concerned about potential liability. Safe Harbor 401(k) plans have specific rules regarding employee eligibility, employer contributions, and vesting, which are intended to make the plan more attractive to employees and reduce the risk of discrimination claims.

Employer Contributions

One of the main benefits of a safe harbor 401(k) plan is that it provides employers with a safe harbor from the top-heavy rules and the non-discrimination testing requirements. This means that employers do not have to worry about whether their plan meets these requirements if they make the required contributions to their employees’ accounts.

  • Matching contributions: Employers can make matching contributions to their employees’ accounts up to a certain percentage of their compensation. The maximum matching contribution is 100% of the employee’s contribution, up to a limit of $58,000 in 2023 ($64,500 for employees who are age 50 or older).
  • Non-matching contributions: Employers can also make non-matching contributions to their employees’ accounts. The maximum non-matching contribution is 100% of the employee’s compensation, up to a limit of $66,000 in 2023 ($73,500 for employees who are age 50 or older).
    Contribution TypeMaximum Contribution
    Matching contributions100% of employee’s contribution, up to $58,000 ($64,500 for employees age 50+)
    Non-matching contributions100% of employee’s compensation, up to $66,000 ($73,500 for employees age 50+)

    Employers can choose to make either matching contributions or non-matching contributions, or a combination of both. However, they must make the same type of contribution to all of their employees who are eligible for the plan.

    Safe Harbor 401k Plans

    Safe Harbor 401k plans are employer-sponsored retirement plans that offer unique advantages to both employers and employees. These plans meet specific requirements set by the Internal Revenue Service (IRS), which provide employers with a “safe harbor” from certain nondiscrimination testing requirements.

    One of the key benefits of Safe Harbor 401k plans is automatic enrollment, which is a feature that helps employees save for retirement without requiring them to take any action.

    Automatic Enrollment

    • All eligible employees are automatically enrolled in the plan.
    • Employees may choose to opt out of the plan within 90 days of enrollment.
    • Default contribution rates are typically set between 3% and 6% of the employee’s salary.
    • Employees may increase or decrease their contribution rate at any time.

    Safe Harbor 401k plans also offer generous employer matching contributions, which can significantly boost employees’ retirement savings.

    Employer Contribution TypeMinimum Contribution
    Matching Contributions100% of the first 3% of compensation, plus 50% of the next 2% of compensation
    Nonelective Contributions3% of compensation for all eligible employees

    Overall, Safe Harbor 401k plans are a valuable retirement savings tool for both employers and employees. They provide a simplified and automatic way to save for retirement, while also offering generous employer contributions.

    Forfeiture Provisions

    Forfeiture provisions allow employers to reclaim unvested (i.e., not yet owned) contributions if an employee leaves the company before meeting certain conditions, such as:

    • Working for a specified period
    • Reaching a certain age
    • Becoming vested

    However, Safe Harbor plans have more restrictive forfeiture provisions than traditional 401(k) plans, prohibiting forfeiture once an employee becomes vested. This protection ensures that employees have full ownership of their vested contributions, regardless of when they leave the company.

    Safe Harbor 401k Plans

    A safe harbor 401k is a qualified retirement plan that is designed to help employers comply with complex nondiscrimination rules. Here are the key features of a safe harbor 401k plan:

    Nondiscrimination Testing

    Safe harbor 401k plans are not subject to regular nondiscrimination testing. This means that employers do not have to prove that their plan does not discriminate in favor of highly compensated employees.


    There are some exceptions to this rule. For example, employers must still test their plan if they make significant changes to the plan’s design or if the plan fails to meet the safe harbor requirements for two consecutive years.

    The table below summarizes the nondiscrimination testing requirements for safe harbor 401k plans:

    Safe Harbor TypeNondiscrimination Testing
    Traditional Safe HarborNot required
    Enhanced Safe HarborRequired if plan fails to meet certain conditions
