Safe Harbor 401(k): 2024 Guide For Employers
Navigating the world of retirement plans can be overwhelming, especially when deciding between traditional 401(k) plans and safe harbor 401(k) plans. Safe Harbor plans help ensure employees reap the benefits of tax-advantaged retirement savings and help enable executives to max out their personal contributions to the new 2024 contribution limits ($69,0000 or $76,500 for employees 50+). In 2023, 35% of small businesses offered a safe harbor plan because they’re easy to administer and popular with employees.
What is a Safe Harbor 401(k) Plan?
A safe harbor plan is a type of 401(k) that ensures all eligible employees receive a company contribution (like a company match). Unlike a traditional 401(k), a safe harbor plan doesn’t require business owners to perform annual nondiscrimination testing. Specifically, Safe Harbor plans allow you to automatically pass non-discrimination tests and are great for family-owned businesses and plans with low participation. If a plan includes the following safe harbor provisions, it automatically passes non-discrimination tests:
- A minimum safe harbor contribution to employees (typically 3% Safe Harbor Non-elective contribution to every employee or a 4% Safe Harbor Match).
- Immediate vesting of employer safe harbor contributions.
The Benefits of Safe Harbor Plans
The Safe Harbor 401(k) plan is an innovative approach that allows employers to bypass the daunting IRS nondiscrimination testing. This allows employers to maintain a balanced 401(k) plan without facing the potential complexities and penalties of traditional 401(k) plans. Additionally, Secure Act 2.0 provides tax credits which may cover up to 100% of employer costs and greatly subsidize Safe Harbor contributions. To create a Safe Harbor 401(k), employers generally commit to providing a company 401(k) contribution between 3% to 6% of employee pay.
Types of Safe Harbor 401(k) Plans
There are three types of safe harbor 401(k) plans, each with its own features and requirements. The success and cost of a Safe Harbor 401(k) depend heavily on key decisions: the contribution formula, eligibility, vesting and auto-enrollment.
Traditional Safe Harbor
A traditional safe harbor plan requires employers to contribute between 3% and 4% of eligible employee pay to the 401(k). These contributions must also be 100% vested immediately. Employers have two choices on how to make contributions: a 3% Non-elective contribution to every eligible employee's pay, or a 4% Match (a 100% match on the first 3% of an employee’s contribution and a 50% match on the next 2%).
Enhanced Safe Harbor
Enhanced safe harbor contributions must also vest immediately; however, employers can structure their contribution to be more generous than the traditional safe harbor plan. For example, employers may match 100% of the first 4%, 5%, or 6% of compensation. However, the enhanced Safe Harbor match cannot require employees to contribute more than 6% of their pay to get the full match.
Qualified Automatic Contribution Arrangement (QACA)
QACA plans are a great choice for employers that want a safe harbor but also want to vest contributions. QACAs require employers to automatically enroll employees in the plan but allow for a 2-year cliff vesting schedule. This is a great option for employers setting up a new 401(k) plan because it automatically complies with the SECURE 2.0 Act of 2022, which requires all plans starting in 2024 to adopt automatic enrollment. Another benefit of QACAs is that the employer match is 3.5% — lower than the 4% match of a traditional safe harbor plan.
Safe Harbor Contribution Comparison
The following table outlines the different contribution formulas and vesting requirements based on the plan design:
| Plan Design | Required Contribution | Vesting Schedule |
|---|---|---|
| Traditional Safe Harbor (Match) | 4% Match (100% on first 3%, 50% on next 2%) | Immediate |
| Traditional Safe Harbor (Non-elective) | 3% of compensation for all eligible employees | Immediate |
| QACA Safe Harbor | 3.5% Match (100% on first 1%, 50% on next 5%) | Up to 2-year cliff |
| Enhanced Safe Harbor | At least 4% Match (e.g., 100% on first 4%) | Immediate |
Selecting the right Safe Harbor contribution option is one of the most effective ways to control plan costs and help you meet your goals. Safe Harbor plans help ensure employees reap the benefits of tax-advantaged retirement savings and help enable executives to max out their personal contributions.
