SIMPLE IRA

A SIMPLE IRA (Savings Incentive Match Plan for Employees) is a low-overhead retirement plan designed for small businesses with 100 or fewer employees. The employer must contribute either a 2% or 3% match of each employee’s salary or a flat 2% non-elective contribution, and employees can contribute up to roughly $16,000 annually, but funds cannot be withdrawn penalty-free for two years after entry.

A mini-plan for small employers

The SIMPLE IRA arrived in 1996 to give small businesses a retirement plan without the paperwork and cost of a full 401(k). If you run a sole proprietorship or small company with fewer than 100 employees, you can set one up easily. The employer’s job is simple: contribute 2% or 3% of each employee’s gross pay, or match employee deferrals up to 3%. That’s it. No safe-harbor testing, no complicated compliance, no annual filings with the Department of Labor.

The catch is the lock-in: if an employee withdraws funds within two years of opening the account (or joining), the penalty is 25%, not the standard 10% for early withdrawal. This steep penalty discourages raiding the plan during the first twenty-four months. After two years, the money is treated like any other IRA, and standard early withdrawal rules apply.

The employer match: 3% or 2%

Employers choose one of two paths. The 3% match means: for each 1% an employee defers up to 3% of salary, the employer adds 1%. So if an employee contributes 2% of salary, the employer adds 2%; if the employee contributes 3%, the employer adds 3%. The employee can defer up to 100% of salary (within the dollar limit), but the match caps at 3%.

The second option is a 2% non-elective contribution. The employer contributes 2% of every eligible employee’s salary—whether or not the employee defers anything. This ensures all staff benefit from the plan without requiring them to contribute. The drawback: you pay for employees who do not use the plan.

Most small employers choose the 3% match because it rewards participation: employees who care about saving get the full match; those who skip the plan cost the employer less.

Much lower contribution limits than a 401(k)

The annual employee deferral limit is around $16,000 (as of 2024), with a $3,500 catch-up for workers 50 and older. A traditional 401(k) allows roughly $23,500, and a Solo 401(k) for self-employed workers permits even higher aggregate contributions. The SIMPLE IRA is intentionally modest—it is meant for workers who cannot access an employer plan elsewhere and for employers who want low complexity.

For a sole proprietor or small business owner wanting to save more, the SIMPLE IRA is a trap. You cannot contribute enough as an employee through deferral alone. However, you can also open a SEP IRA alongside it (or instead of it), or a Solo 401(k) if you have no employees. Many small employers later switch to a Solo 401(k) as they grow or want higher savings.

The two-year penalty: why it matters for rollovers

Here is the critical rule: a SIMPLE IRA withdrawal within two years of the account opening (or an employee joining) triggers a 25% penalty instead of the 10% early-withdrawal penalty. After two years, the 25% penalty goes away, and the standard early withdrawal rules apply—10% if you are under 59½, with exceptions for hardship, substantially equal payments, or other IRS-approved reasons.

The 25% lock-in has a surprising consequence for rollovers. You cannot roll a SIMPLE IRA to a traditional IRA or 401(k) during the first two years if you do it through a trustee-to-trustee transfer. The IRS treats this as an indirect rollover, which is subject to the 25% early-withdrawal penalty if the two-year window has not closed. However, many custodians interpret the rules loosely and permit the move anyway; you should verify with your plan administrator.

After two years, rollover restrictions lift entirely. You can move SIMPLE IRA funds to a traditional IRA, a Roth IRA (via Roth conversion), or an employer 401(k) if you change jobs. This flexibility makes the SIMPLE IRA less of a cage once you survive the lock-in period.

Who offers SIMPLE IRAs?

Any business with 100 or fewer employees can set one up. You do not need to be incorporated; sole proprietors, partnerships, and S-corporations all qualify. Once you exceed 100 employees, you must close the SIMPLE IRA and offer a 401(k) or other plan instead (or you can keep it frozen for existing participants).

Many small employers stick with SIMPLE IRAs throughout the life of the business because the compliance burden is light. Employers must file a one-page Form 5304-SIMPLE or 5305-SIMPLE with the IRS, but there are no annual testing requirements and no filing of Form 5500 (the 401(k) equivalent). Some plans are offered through banks or mutual funds with pre-built documents, making setup nearly instantaneous.

Tax treatment: pre-tax deferrals, employer match not taxed

Employee deferrals to a SIMPLE IRA are pre-tax—they reduce your taxable income in the year you contribute. The employer’s match or non-elective contribution is not taxable income to the employee either. Growth inside the account is tax-deferred. You pay ordinary income tax on withdrawals starting at age 59½ (or at any age via Roth conversion).

Some employers offer a “SIMPLE Roth IRA” option—the employee’s deferrals are after-tax (like a Roth), but the employer’s match still arrives pre-tax. This is less common than the traditional SIMPLE because employers and employees find the hybrid structure confusing.

When a SIMPLE IRA makes sense

A SIMPLE IRA suits very small employers (fewer than 25–30 employees) who want a bare-bones plan with minimal paperwork. It also appeals to side-gig founders or consultants who hire a few contractors or part-time staff. If you are the only employee, a Solo 401(k) or SEP IRA usually saves more and offers better flexibility.

Employees should understand the two-year lock-in before enrolling. If you expect to change jobs within two years, the 25% penalty on early withdrawal is steep. After the two-year hurdle, a SIMPLE IRA is just a traditional IRA and behaves like any other retirement savings.
