What is a Salary Reduction Simplified Employee Pension Plan (SARSEP)?

A Salary Reduction Simplified Employee Pension Plan (SARSEP) is a type of retirement savings plan designed for small businesses that allows employees to make pre-tax contributions to an Individual Retirement Account (IRA). SARSEPs were widely available prior to 1997 but are now restricted to plans established before that year. While no new SARSEPs can be created, businesses that set them up before 1997 can still maintain and contribute to them.

Key Features of SARSEP

Eligibility Criteria for Employers
To establish a SARSEP, an employer must meet certain criteria:

• The business must have had 25 or fewer eligible employees during the previous year.
• At least 50% of eligible employees must participate in the plan.
• The plan must allow employees to elect to have their salary reduced and contribute the reduced amount to their SEP-IRA.
• Only employees who are at least 21 years old, have worked for the employer in at least three of the last five years, and earned at least $750 in the previous year are eligible to participate in a SARSEP.

Employee Contributions
The defining feature of a SARSEP is the salary reduction option. Employees can choose to reduce their salary by a certain percentage or amount and contribute that money, pre-tax, to a SEP-IRA. The maximum contribution limit is the lesser of 25% of the employee's compensation or the standard contribution limit set by the IRS for elective deferrals. In 2024, for example, this elective deferral limit was $23,000, with an additional catch-up contribution of $7,500 for employees aged 50 or older.

Employer Contributions
Employers can also contribute to the SEP-IRAs of eligible employees. These contributions are optional and must be made equally for all eligible employees, regardless of whether they participate in the salary reduction option. The combined employer and employee contributions cannot exceed 25% of an employee’s compensation, up to an annual maximum set by the IRS.

Vesting
All contributions to a SARSEP are immediately vested. This means that employees have 100% ownership of their SEP-IRA balances from the moment the funds are deposited. There are no vesting schedules or waiting periods for accessing the funds.

Tax Advantages

Pre-Tax Contributions
One of the primary advantages of SARSEPs is that employee contributions are made with pre-tax dollars. This reduces the employee's taxable income for the year, lowering their immediate tax liability. For example, if an employee earns $50,000 annually and contributes $5,000 to their SEP-IRA through salary reduction, their taxable income for that year would be reduced to $45,000.

Tax-Deferred Growth
The funds in a SEP-IRA grow tax-deferred until the employee withdraws them, typically in retirement. This means that no taxes are paid on investment earnings (such as interest, dividends, or capital gains) until the funds are withdrawn. This tax deferral can help the account grow more quickly over time, as compounding occurs without the drag of annual taxes.

Tax on Withdrawals
Withdrawals from a SEP-IRA, like those from traditional IRAs, are taxed as ordinary income in the year they are taken. Early withdrawals (before age 59½) are generally subject to a 10% penalty in addition to ordinary income tax unless they meet certain exceptions, such as for qualified educational expenses, first-time home purchases, or specific medical expenses.

Disadvantages and Limitations

Restricted Availability
The most significant limitation of a SARSEP is that new plans cannot be established. Businesses that did not set up a SARSEP by 1997 must use other types of retirement plans, such as a SEP-IRA (without the salary reduction feature), a SIMPLE IRA, or a 401(k).

Limited to Small Employers
SARSEPs are only available to small businesses with 25 or fewer eligible employees. Companies that grow beyond 25 employees or fail to meet the 50% participation requirement cannot continue using a SARSEP.

Contribution Limits
While SARSEP contribution limits are generous, they may not be as high as those for other retirement plans. For example, a 401(k) plan may allow for higher total contributions when including employer matches, profit-sharing, or other employer contributions.

SARSEP vs. Other Retirement Plans

SARSEPs vs. SEP-IRAs
Both SARSEPs and SEP-IRAs are employer-sponsored retirement plans, but the key difference is that SARSEPs allow for employee salary reductions, while SEP-IRAs do not. Employers can still contribute to both types of plans, but only a SARSEP offers the option for employees to defer part of their salary into the plan.

SARSEPs vs. 401(k) Plans
While SARSEPs offer a simpler and less administratively burdensome option than a 401(k), they are more restrictive in terms of employee numbers and participation requirements. A 401(k) plan offers higher contribution limits, more investment options, and greater flexibility for larger employers.

SARSEPs vs. SIMPLE IRAs
SIMPLE IRAs, introduced after SARSEPs were discontinued for new plans, are designed specifically for small businesses. They offer a similar structure, allowing employee contributions and employer matches, but with lower contribution limits than a 401(k) plan and less administrative complexity.

The Bottom Line

A Salary Reduction Simplified Employee Pension Plan (SARSEP) is a retirement savings option designed for small businesses with 25 or fewer employees, combining employer contributions and employee salary deferrals. While new SARSEPs cannot be created, those established before 1997 continue to provide a tax-advantaged way for employees to save for retirement. The key benefits include immediate vesting, pre-tax contributions, and tax-deferred growth. However, SARSEPs are limited to smaller employers and have stricter contribution limits compared to more modern retirement plans like 401(k)s or SIMPLE IRAs.
