Key Points
Overview
Beginning in 1997, small employers became permitted to offer a Savings Incentive Match Plan for Employees (SIMPLE plan), provided they do not maintain another qualified retirement plan. SIMPLE plans were created by Congress specifically to give small businesses an easy, low-cost way to offer employees a retirement savings vehicle with elective deferrals — filling the gap left when new SARSEPs were prohibited after 1996.
SIMPLE plans may be structured as:
- a SIMPLE IRA — employer contributions and employee deferrals are deposited into individual IRA accounts for each participant, or
- a SIMPLE 401(k) — contributions are deposited into a 401(k) plan maintained by the employer.
SIMPLE plans allow employees to make elective salary deferrals each year. They also require a minimum annual employer contribution — either a matching contribution or a non-elective contribution. In exchange for these mandatory contributions, SIMPLE plans are exempt from the complex nondiscrimination testing, top-heavy rules, and burdensome reporting obligations that apply to traditional 401(k) and other qualified plans.
Why SIMPLE Plans?
Small employers face a dilemma when offering retirement benefits: traditional 401(k) plans provide powerful savings tools but come with significant administrative complexity and cost — annual nondiscrimination testing, top-heavy rules, Form 5500 filings, and ERISA compliance. For small businesses, the cost and burden often outweigh the benefits.
SIMPLE plans offer a purpose-built solution:
| Feature | SIMPLE Plan | Traditional 401(k) |
|---|---|---|
| Employer size limit | 100 or fewer employees | No limit |
| Employee elective deferrals | Yes — $17,600 (2026) | Yes — $24,500 (2026) |
| Mandatory employer contribution | Yes (3% match or 2% non-elective) | No |
| ADP/ACP nondiscrimination testing | Not required | Required (unless Safe Harbor) |
| Top-heavy rules | Not applicable | Apply if top-heavy |
| Form 5500 filing (SIMPLE IRA) | Not required | Required |
| Can maintain another qualified plan | No | Yes |
| SIMPLE IRA 2-year restriction | Yes — 25% early withdrawal penalty | N/A |
Congress prohibited new SARSEPs (salary reduction SEPs) after December 31, 1996, and introduced SIMPLE plans as the replacement vehicle for small employers wanting to offer employee elective deferrals. SIMPLE plans are simpler to administer than SARSEPs while providing similar employee deferral benefits, mandatory employer contributions, and exemption from most nondiscrimination testing.
2026 Contribution Limits
| Item | 2026 Limit |
|---|---|
| Employee elective deferral | $17,600 |
| Catch-up (age 50–59 and 64+) | $3,850 additional |
| Super catch-up (age 60–63, SECURE Act 2.0) | $5,250 additional (150% of standard catch-up) |
| Employer matching contribution (standard) | Dollar-for-dollar up to 3% of compensation |
| Employer matching contribution (reduced — max 2 of 5 years) | As low as 1% of compensation |
| Employer non-elective contribution (alternative) | 2% of compensation for all eligible employees |
| Compensation cap for non-elective contribution | $360,000 |
SIMPLE plan deferral limits are separate and lower than 401(k) deferral limits ($24,500). An employee who participates in a SIMPLE plan and also defers into another elective plan must count both amounts toward their respective limits.
