SIMPLE IRA vs. Roth IRA: What’s the Difference — and Can You Have Both?

Correction: We corrected withdrawal and rollover summaries, Roth SIMPLE qualifications and contribution coordination. Earlier corrections remain in the history. See corrections and updates.

A SIMPLE IRA plan is an employer retirement arrangement; a regular Roth IRA is a personal retirement account. For 2026, SIMPLE salary reductions are generally limited to $17,000, or $18,100 for an eligible enhanced arrangement, before catch-ups. The regular IRA limit is $7,500, or $8,600 at 50+, with compensation and Roth income requirements. You can use both if eligible: their contribution limits are separate, but other tax rules connect them.

Who sets it up, and when is the money taxed?

A SIMPLE IRA plan is generally available to an employer with 100 or fewer employees who received at least $5,000 of compensation in the preceding year. It generally cannot coexist with another employer retirement plan, but exceptions include specified plan-replacement rules. An employer sets up the arrangement, employees can make salary reductions, and the employer contributes under a permitted formula.

A regular Roth IRA is not an employer plan. You choose a provider and make eligible regular contributions. A qualifying joint-return spousal contribution can be available even if one spouse has no compensation of their own.

Traditional SIMPLE contributions generally receive pre-tax treatment, and taxable distributions are ordinary income. A plan may instead offer Roth SIMPLE contributions. That option is not automatic: the employer must offer it and the employee must affirmatively elect Roth treatment before the contribution is made. Roth contributions are included in income, while qualified Roth distributions are tax-free.

Traditional SIMPLE balances have owner RMDs at the applicable starting age. Roth SIMPLE IRAs, like regular Roth IRAs, have no owner lifetime RMDs. Beneficiary rules still apply. For the wider plan rules, see SIMPLE IRA rules.

2026 contribution limits side by side

The age-60–63 SIMPLE amount replaces the ordinary catch-up; it is not added on top of it. Ask the employer which limit applies to the plan. Enhanced arrangements have eligibility and employer-contribution conditions; a higher headline limit does not automatically apply to every small employer.

Traditional and Roth salary reductions under the same SIMPLE plan share the SIMPLE limit. Deferrals to other workplace plans may also require coordination. The regular $7,500/$8,600 IRA limit is shared across your regular Traditional and Roth IRA contributions, not a separate allowance for each account.

What employer money should you expect?

The usual formulas are a dollar-for-dollar match up to 3% of compensation or a 2% nonelective contribution for eligible employees, subject to the applicable compensation rules and cap. A nonelective contribution does not depend on the employee making salary reductions. Permitted reduced-match years and enhanced arrangements can change the formula, so use the employer's actual notice.

SIMPLE contributions are fully vested: the employee owns both their own and the employer's contributions. That does not remove distribution taxes or rollover restrictions.

Can you contribute to both in the same year?

Yes. A 40-year-old eligible for the standard SIMPLE and a full regular Roth contribution in 2026 could contribute $17,000 + $7,500 = $24,500, plus the employer contribution. This example assumes sufficient qualifying compensation remains to support the Roth contribution, no other regular IRA contributions, no conflicting workplace deferrals and income within Roth eligibility limits.

Participating in a SIMPLE does not itself bar a regular Roth IRA contribution. Actual room still depends on compensation, filing status, modified AGI and prior regular IRA contributions. Traditional salary reductions and other adjustments can affect those calculations. Workplace coverage also matters for a separate Traditional IRA deduction.

The Traditional SIMPLE two-year rule

The two-year period starts when contributions are first deposited in your SIMPLE IRA under the plan. For a Traditional SIMPLE distribution in that period, an early distribution that would otherwise face the 10% additional tax generally faces 25% instead. This is not a tax on every withdrawal: age 59½ and other applicable exceptions still matter. Ordinary income tax on the taxable amount is separate.

Rollovers generally must stay within SIMPLE IRAs during those first two years. An otherwise ineligible transfer to a regular Traditional IRA or Roth IRA is not rescued merely by moving the money directly between custodians. Notice 2024-2, Q&A G-4, describes a specific exception for distributions from a terminated SIMPLE plan rolled to qualifying 401(k) or 403(b) arrangements; it is not a general permission to convert early.

After the two-year period, an eligible Traditional SIMPLE amount can generally be rolled to a Traditional IRA or converted to a Roth IRA. A conversion generally creates income tax on its pre-tax portion. Required minimum distributions cannot be rolled over or converted.

Do not apply this Traditional-balance summary mechanically to Roth SIMPLE money. Confirm the account type, the plan's records and the applicable Roth distribution and transfer rules with the provider.

A regular Roth IRA has a different withdrawal order

Nonqualified withdrawals generally return remaining regular contribution basis first, then conversions and certain rollovers in year order, then earnings. Recent taxable conversions can face the 10% additional tax before age 59½ if their separate five-tax-year period is unfinished and no exception applies. It is therefore incorrect to say that only earnings have withdrawal restrictions.

Qualified Roth earnings withdrawals are tax-free. The usual age-based route needs both 59½ and the Roth five-tax-year period. Age 59½ removes the usual early-distribution tax even if the earnings qualification clock is unfinished, but those earnings can still be taxable.

The backdoor Roth connection

Form 8606 generally aggregates your Traditional, traditional SEP and traditional SIMPLE IRA balances for the pro-rata calculation. A pre-tax Traditional SIMPLE balance can therefore make a conversion partly or mostly taxable even if the new Traditional IRA contribution was nondeductible. Roth IRA balances are not part of that Traditional IRA aggregation.

See the backdoor Roth guide before treating a nondeductible contribution followed by a conversion as automatically tax-free.

Which should you fund first?

There is no universal order. Start by identifying whether employee contributions are needed to receive the employer's match; a nonelective formula works differently. Then compare current and future tax treatment, fees, investment choices, access needs and eligibility for the regular Roth contribution. A workplace Roth SIMPLE option changes the comparison with a pre-tax-only plan.

The separate limits create choices, not a requirement to fund one account before the other. This is an educational framework, not a recommendation for a particular saver.

September 24, 2026 — Correction: Corrected the earnings-only description of Roth restrictions, the blanket two-year transfer and penalty statements, Roth SIMPLE owner-RMD and election qualifications, and compensation/pro-rata coordination. Removed an unsupported adoption claim and universal funding-order recommendation. Correction record.

August 28, 2026 — Correction: We corrected the enhanced SIMPLE catch-up, Roth-option and employer-formula language, and qualified the two-year additional-tax rule. See the correction record.
