What is a SIMPLE IRA?

A SIMPLE IRA (Savings Incentive Match Plan for Employees) is an employer-sponsored retirement plan built for small businesses. It sits between a traditional IRA and a 401(k): higher contribution limits than an IRA, mandatory employer contributions, and far less administrative burden than a 401(k).

Eligibility is the defining constraint. Only employers with 100 or fewer employees who earned at least $5,000 in the prior year can offer one, and the employer generally cannot maintain another qualified retirement plan at the same time.

How Contributions Work

Two sources fund a SIMPLE IRA, and unlike most plans, the employer half is not optional.

Employee deferrals come out of your paycheck up to an annual limit set by the IRS. The limit is lower than a 401(k) but roughly double a traditional IRA, with an additional catch-up allowance from age 50. SECURE 2.0 added higher limits for employers with 25 or fewer employees, and an elective higher limit for employers with 26 to 100 employees who increase their match. Contribution limits change annually and the tiering makes them unusually easy to get wrong, so confirm the current figures for your employer size before contributing.

Employer contributions are mandatory. The employer must choose one of two formulas each year:

The 3% match can be reduced to as low as 1% in two out of any five consecutive years, provided employees are notified in advance. Outside that exception, the employer contribution is a real obligation, which is the main reason a business chooses a SIMPLE IRA deliberately rather than by default.

If your employer matches, contributing at least 3% of your salary is the difference between capturing that money and leaving it behind.

The Two-Year Rule

This is the SIMPLE IRA’s sharpest edge and the detail most participants never hear about.

Withdrawals taken within two years of your first contribution to the plan face a 25% early distribution penalty in place of the usual 10%. The clock runs from your first contribution date, not from each contribution.

Importantly, the 25% substitutes for the standard early withdrawal penalty rather than adding a new one, so it only bites where that penalty would apply anyway. If you are 59 1/2 or older, or another exception covers you, no penalty is due at all.

The same two-year window restricts rollovers. During it, you can only roll a SIMPLE IRA into another SIMPLE IRA. Rolling into a traditional IRA or a 401(k) before the two years are up is treated as a distribution, so the balance becomes taxable income, with the 25% penalty on top if you are under 59 1/2.

After two years the account behaves like a traditional IRA: the early withdrawal penalty reverts to the standard 10% where it applies, and you can roll the balance anywhere.

SIMPLE IRA vs. Other Small Business Plans

A SIMPLE IRA is generally the right answer for a small business that wants to offer something meaningful to employees without payroll-plan complexity. A self-employed person with no staff can almost always contribute more through a solo 401(k).

Other Details Worth Knowing

Immediate vesting. All contributions, including the employer’s, are 100% yours from day one. There is no vesting schedule, which is a genuine advantage over many 401(k) plans.

Roth contributions are now allowed. SECURE 2.0 permits Roth treatment of SIMPLE IRA deferrals, though adoption depends on whether your employer and custodian support it.

No loans. Unlike a 401(k), you cannot borrow against a SIMPLE IRA.

Contributions are pre-tax by default, reducing your adjusted gross income in the contribution year, with distributions taxed as ordinary income later.

Whether to prioritize a SIMPLE IRA over other savings depends on the match, your bracket now versus in retirement, and what else is available to you.

Frequently Asked Questions

How much can I contribute to a SIMPLE IRA? More than a traditional IRA, less than a 401(k), with a catch-up allowance from age 50 and higher limits for employers with 25 or fewer employees under SECURE 2.0. Limits change annually, so confirm the current figure for your employer size.

Does my employer have to contribute? Yes. Employer contributions are mandatory: either a dollar-for-dollar match up to 3% of your compensation, or 2% of compensation for every eligible employee regardless of whether they contribute.

What is the SIMPLE IRA two-year rule? Withdrawals within two years of your first contribution face a 25% early distribution penalty instead of the usual 10%, and during that window the account can only be rolled into another SIMPLE IRA. The penalty only applies if you would otherwise owe the early withdrawal tax, so it does not affect participants who are 59 1/2 or older.

Can I have a SIMPLE IRA and a Roth IRA? Yes. They have separate limits. Roth IRA eligibility still depends on your income, and participating in a SIMPLE IRA counts as workplace plan coverage for traditional IRA deductibility purposes.

What happens to my SIMPLE IRA if I leave the job? It stays yours, fully vested. After the two-year window you can roll it into a traditional IRA or a new employer’s plan, or leave it where it is.

Can I take a loan from a SIMPLE IRA? No. SIMPLE IRAs follow IRA rules, which prohibit loans. A 401(k) is the plan type that generally permits borrowing.
