Small-employer retirement plan combining employee salary deferrals with required employer contributions, individual IRA accounts, and simplified administration.
A SIMPLE IRA, or Savings Incentive Match Plan for Employees, is an employer-sponsored retirement plan that deposits employee salary deferrals and required employer contributions into an IRA established for each eligible employee. It is designed for qualifying smaller employers that want less administration than many 401(k) plans require.
An eligible employer generally has 100 or fewer employees who received at least a specified amount of compensation in the preceding year and generally does not maintain another retirement plan for employees during the same year. The tax law contains transition and other rules, so an employer near the limit or involved in an acquisition should not rely on headcount alone.
The employer adopts a plan document, arranges a SIMPLE IRA for each eligible employee, provides required notices and an election period, processes salary reductions through payroll, and deposits contributions on time.
The plan is available to qualifying businesses and can include a self-employed individual. It is not limited to corporations, and choosing a SIMPLE IRA creates responsibilities for eligible employees rather than only for owners.
The standard statutory eligibility test generally covers an employee who:
An employer may use less restrictive requirements. Limited exclusions can apply, including certain collectively bargained employees and certain nonresident aliens without U.S. compensation from the employer.
An eligible employee can elect no salary deferral, but that does not necessarily remove the employee from the plan. Under a nonelective employer contribution, an eligible employee can receive an employer contribution even after choosing not to defer salary.
| Contribution | Who decides? | General operation |
|---|---|---|
| Employee salary reduction | Employee, within annual limits and plan procedures | Payroll redirects elected compensation to the employee’s SIMPLE IRA |
| Employer matching contribution | Employer selects the method for the year under plan rules | Standard design generally matches employee deferrals dollar for dollar up to 3% of compensation |
| Employer nonelective contribution | Employer selects the method for the year under plan rules | Standard design generally contributes 2% of compensation for each eligible employee, including employees who do not defer |
| Additional or enhanced provisions | Employer if current law and plan terms permit | SECURE 2.0 added options for certain plans; current IRS guidance and the adopted document control |
The employer must communicate its contribution method through the required annual notice. A standard match can be reduced only under specific conditions and frequency limits. Employers should not assume they can skip contributions during a weak business year.
Roth SIMPLE IRA contributions may be available if the plan and custodian support them. Traditional and Roth salary reductions have different current income-tax treatment, and employer contribution treatment depends on applicable law and plan elections.
Assume an eligible employee earns $60,000 and elects to defer 5% of salary. Ignore annual limits and catch-up contributions for this illustration.
The employee does not receive a match on the final 2 percentage points because the standard match stops at 3% of compensation. If the employer instead elected the standard 2% nonelective method, the employer contribution would be $1,200 whether the employee deferred $3,000 or zero.
Actual payroll, compensation definitions, annual limits, enhanced provisions, and plan documents can change the result.
| Feature | SIMPLE IRA | SEP IRA | 401(k) plan |
|---|---|---|---|
| Employee salary deferrals | Yes | Generally no under a current SEP | Yes |
| Employer contribution | Required under selected SIMPLE method | Employer funded and generally discretionary by year | Depends on plan design; match or nonelective contribution may be offered or required |
| Vesting | Immediate | Immediate | Employee deferrals immediate; employer contributions can have a schedule unless rules require otherwise |
| Loans | Not permitted | Not permitted | May be permitted by the plan |
| Administration | Simplified IRA-based structure | Often simplest employer-funded structure | More design flexibility and generally more administration |
| Typical decision issue | Balance payroll saving with required employer funding | Flexible employer funding, especially for owners and small staffs | Higher design flexibility, testing, and administrative responsibilities |
The best comparison depends on employee demographics, owner goals, payroll, contribution capacity, plan costs, tax treatment, and whether the business expects to grow.
Operational errors can undermine a plan even when the design is appropriate. Employers should verify:
An excluded employee or incorrect employer contribution may require correction and earnings adjustments. The IRS SIMPLE IRA Fix-It Guide describes common failures and correction approaches.
An employee owns the account and can request a distribution, but access can create tax consequences. Taxable distributions are generally included in income. An additional tax can apply to an early distribution unless an exception applies.
During the two-year period beginning when the employee first participates, the additional tax on an otherwise taxable early distribution is generally 25% rather than 10%. During that period, tax-free transfers generally must go to another SIMPLE IRA. After the period, broader rollover destinations can become available under the applicable rules.
The two-year period begins with participation as defined by IRS rules, not simply the calendar year or employment start date. Before moving or withdrawing funds, confirm the first contribution date, receiving account type, transfer method, and any exception.
