Quick Answer: A SEP-IRA lets only the employer contribute, up to the lesser of $72,000 or 25% of compensation, with immediate 100% vesting. A SIMPLE IRA requires both employee deferrals (up to $17,000) and mandatory employer contributions, capped at employers with 100 or fewer employees, with a steep 25% early withdrawal penalty in the first 2 years.
7,000) and mandatory employer contributions, capped at employers with 100 or fewer employees, with a steep 25% early withdrawal penalty in the first 2 years.For small businesses and self-employed individuals, setting up a full 401(k) plan can be complex and expensive. SEP-IRAs and SIMPLE IRAs offer simpler alternatives with meaningful retirement savings capacity.
How Does a SEP-IRA Work?
A SEP-IRA allows the employer to contribute directly to employees' individual retirement accounts with minimal administrative burden.
What Are the Key Features?
- Maximum contribution (2026): lesser of $72,000 or 25% of compensation
- Compensation cap (2026): $360,000 (only the first $360,000 of an employee's pay is considered)
- Only the employer contributes; no employee elective deferrals (except under a Salary Reduction SEP (SAR-SEP) grandfathered before 1997)
- Ideal for self-employed individuals and small businesses
- Immediate 100% vesting; once the employer contributes, the money belongs to the employee
- Contributions are tax-deductible for the employer
- Very simple to establish; completed by filing the IRS SEP setup form
Who Must an Employer Cover?
Employers must generally cover employees who:
- Are at least age 21
- Have worked for the employer in at least 3 of the last 5 years
- Received at least $800 in compensation (2026)
Exam Tip: Gotchas
- SEP-IRA contributions come from the employer only. Employees do not make elective deferrals.
- Both SEP and SIMPLE IRAs vest immediately with no vesting schedule.
How Does a SIMPLE IRA Work?
A SIMPLE IRA is designed for small employers and provides both employee deferrals and mandatory employer contributions.
What Are the Eligibility Requirements?
- Available to employers with 100 or fewer employees who earned at least $5,000 in the preceding year
- The employer generally cannot maintain any other retirement plan
What Are the 2026 Contribution Limits?
- Employee deferral limit: $17,000 ($18,100 for a SIMPLE plan of an employer with 25 or fewer employees, under a SECURE 2.0 enhanced-limit election)
- Age 50+ catch-up: $4,000
- Age 60-63 super catch-up: $5,250
- Employer must either:
- Match employee contributions dollar-for-dollar up to 3% of compensation, OR
- Make a 2% non-elective contribution for all eligible employees (regardless of whether they contribute)
Exam Tip: Gotchas
- The $18,100 enhanced deferral limit only applies to SIMPLE plans sponsored by small employers (25 or fewer employees) that elect the higher limit. The standard $17,000 limit applies to every other SIMPLE IRA.
Why Does SIMPLE Have a 25% Early Withdrawal Penalty?
This is a key SIMPLE IRA rule:
- Distributions within the first 2 years of participation carry a 25% early withdrawal penalty (instead of the standard 10%)
- After 2 years, the standard 10% penalty applies for withdrawals before age 59-1/2
- During the first 2 years, a SIMPLE IRA can only be rolled over to another SIMPLE IRA
- After 2 years, rollovers to a traditional IRA or other qualified plan are permitted
Exam Tip: Gotchas
- SIMPLE IRA early withdrawals within the first 2 years carry a 25% penalty, not the standard 10%. The 2-year period starts from the date of the employee's first participation in the plan, not from each contribution.
- SIMPLE IRA employer contributions are mandatory: the employer must match up to 3% or make a 2% non-elective contribution.
How Do SEP-IRA and SIMPLE IRA Compare?
| Feature | SEP-IRA | SIMPLE IRA |
|---|---|---|
| Who contributes | Employer only | Both (employee deferrals + employer match/non-elective) |
| Max contribution (2026) | $72,000 or 25% of comp | $17,000 employee + employer match |
| Employer size limit | None | 100 or fewer employees |
| Employer contribution | Discretionary | Mandatory (match or 2% non-elective) |
| Vesting | Immediate (100%) | Immediate (100%) |
| Early withdrawal penalty | Standard 10% | 25% in first 2 years |
| Ideal for | Self-employed, small business | Small employers wanting employee participation |
What Should You Check on Exam Day?
- Remembered only the employer contributes to a SEP-IRA; a SIMPLE IRA requires both employee deferrals and a mandatory employer match or non-elective contribution.
- Confirmed SIMPLE IRA eligibility is capped at employers with 100 or fewer employees; SEP-IRA has no such employer-size cap.
- Applied the SIMPLE IRA's 25% early withdrawal penalty only within the first 2 years of participation, measured from the date of first participation, not each contribution.
- Checked both SEP-IRA and SIMPLE IRA vest immediately at 100%, unlike employer plans with graded or cliff vesting schedules.
