SIMPLE IRA or 401(k)? 4 Key Differences to Share with Small Business Clients
There are a few choices available to small business clients regarding their retirement plan options; chief among them is the SIMPLE IRA (Savings Incentive Match Plan for Employees) and traditional 401(k) plans.

Both 401(k) plans and SIMPLE IRAs allow employees to contribute part of each paycheck to a retirement investment account. The contributions grow tax-free until an employee accesses the funds in retirement. In both plans, employer contributions can lead to even greater savings. However, 401(k) plans and SIMPLE IRAs have their differences.
While a SIMPLE IRA offers certain benefits to small business owners, a 401(k) may offer other advantages. For example, 401(k) plans can be combined with other retirement plans, while SIMPLE IRAs cannot. And as its name implies, the SIMPLE IRA can be easier and less expensive to set up than a 401(k) plan.
As clients seek guidance and counsel, share the following four key differences to help them consider their options:
1. Employee Contribution Limits
Employees with 401(k) plans can contribute more to their retirement savings than those with SIMPLE IRAs. In 2022, for example, the 401(k)-deferral limit for individuals under the age of 50 is $20,500 compared to a deferral rate of just $14,000 for the SIMPLE IRA, and for those over 50, the limits are $27,000 and $17,000, respectively.
The higher contribution limits of a 401(k) plan mean participants can experience greater savings and lower taxable incomes. In addition, a 401(k) can help business owners maximize their own retirement savings while providing a richer retirement option to attract talent. Note that there are additional options to the 401(k) that can help business owners and key employees increase retirement savings.
2. Employer Contributions
With 401(k) plans, employers can choose whether to match contributions and in what amount. On the other hand, employers with SIMPLE IRA plans are required to contribute to their employees’ retirement accounts. This contribution must match up to 3% of an employee’s annual pay or make a contribution regardless of whether an employee contributes to the plan.
Employers who like the flexibility to decide on the contribution amount might lean toward offering a 401(k) plan as this flexibility can help them better address the financial needs of their business.
3. Retirement Plan Eligibility
When determining who is allowed to join a plan, a 401(k) plan gives employers more control with eligibility rules that can help them meet their 401(k) goals and manage expenses.
Eligibility rules for SIMPLE IRAs, on the other hand, are more restrictive. Employers must offer enrollment to all employees who earned $5,000 in the previous two years and are reasonably expected to earn at least $5,000 in the current year. For some small businesses, this could lead to higher expenses.
4. Vesting Schedules and Retention
Employers who offer a 401(k) plan can set up a schedule for when employees can be vested in non-safe harbor employer contributions. For example, a company may require six months, one year, or whatever fits their plan objectives of employment before an employee is vested. This requirement can help companies foster employee longevity and help them retain key talent.
Vesting schedules are not allowed with SIMPLE IRAs. Employees in these plans are immediately vested in their employer contributions, which may put companies that offer SIMPLE IRAs at a disadvantage when it comes to employee retention.
For advisors whose clients are considering converting their SIMPLE IRA to a 401(k) plan, be sure to:
- Ensure the SIMPLE IRA is the plan sponsor’s sole retirement plan and that it has been in effect for the year.
- Inform plan sponsors that their SIMPLE IRAs can’t be terminated mid-year (they would need to be terminated at year-end).
- Ensure plan participants are notified at least 60 days before the SIMPLE IRA is terminated (i.e., before November 2). The soonest a new 401(k) plan can start is January 1 of the year following the termination of the SIMPLE IRA.[1]
Given these considerations and the continued challenges that exist in the recruitment arena, time is of the essence. For millions of working professionals who are thinking of switching careers, the benefits they are offered may determine whether they accept a certain job offer or continue looking elsewhere. Help your small business clients attract and retain new talent by setting themselves up to meet the expectations of the new labor market successfully.
If your clients are thinking about differentiating their retirement plans and benefits packages, remember that those who make a transition later in the year may find it difficult to fulfill notification requirements and get started the following year. It is not too late to get clients ready for 2023, but you may want to consider seizing the opportunity now to make a change for next year.
