What Is a SIMPLE IRA?
In plain English
A SIMPLE IRA (Savings Incentive Match Plan for Employees) is a retirement plan for small businesses with 100 or fewer employees. Both employees and employers contribute. Employers must either match employee contributions dollar-for-dollar up to 3% of compensation or make a flat 2% contribution for all eligible employees regardless of whether they contribute.
What Are the SIMPLE IRA Contribution Limits?
In 2026, employees can defer up to $16,500 to a SIMPLE IRA, with a $3,500 catch-up contribution for those 50 and older. This is lower than the 401(k) limit but significantly higher than the IRA limit. SECURE 2.0 introduced enhanced catch-up contributions for ages 60–63, allowing up to $5,250 additional beyond the standard catch-up.
What Are the Rules for Withdrawing From a SIMPLE IRA?
Withdrawals are taxed as ordinary income. If you withdraw within two years of starting the plan, the early withdrawal penalty is 25% instead of the usual 10% — a critical distinction. After the two-year period, the standard 10% penalty applies to withdrawals before age 59½. This two-year rule also affects rollovers; you can only roll a SIMPLE IRA to another SIMPLE IRA within that period.
How Does a SIMPLE IRA Compare to a 401(k) for Small Businesses?
A SIMPLE IRA is easier and cheaper to administer than a 401(k) — no annual IRS filing required (Form 5500) and minimal administrative overhead. However, it has lower contribution limits, mandatory employer contributions, and restrictive withdrawal rules. A 401(k) provides more flexibility and higher limits but requires more administrative work. SIMPLE IRAs are best suited for very small businesses wanting a straightforward plan.
Frequently asked questions
Can employees opt out of a SIMPLE IRA?
Yes. Employees can choose not to make their own contributions, but the employer must still make the required 2% non-elective contribution for all eligible employees who earned at least $5,000 if they selected that option. Employees who participate retain all contributions immediately — SIMPLE IRAs have immediate vesting.
Can I have a SIMPLE IRA and a traditional IRA?
Yes, you can contribute to both. However, since you participate in an employer plan, your traditional IRA contribution may not be deductible based on your income. Roth IRA contributions remain available within income limits regardless of SIMPLE IRA participation.
