SIMPLE IRA
A SIMPLE IRA (Savings Incentive Match Plan for Employees) is a retirement plan for small businesses and self-employed people. Employees contribute pre-tax salary, and the employer makes mandatory or matching contributions, all with minimal administrative overhead.
For self-employed only, see SEP IRA; for larger businesses or more complex needs, see 401(k) plan; for individual retirement accounts, see traditional IRA.
How it works
A SIMPLE IRA is a straightforward retirement plan for small businesses. Employees contribute pre-tax salary (up to $16,000 per year for 2024). The employer is required to make contributions in one of two ways:
- Matching contributions. The employer matches 100% of employee contributions up to 3% of salary. For example, an employee earning $50,000 who contributes 3% ($1,500) receives a $1,500 match.
- Non-elective contributions. The employer contributes 2% of all eligible employees’ salaries, regardless of whether they contribute.
This is less complex than a 401(k) and less generous (to employers) than a SEP IRA, making it the middle ground for small firms with employees.
Who should use SIMPLE
- Small businesses with 5–100 employees. A SIMPLE is much simpler than a 401(k) while still providing meaningful employer contributions.
- Self-employed with employees. Unlike a SEP IRA, a SIMPLE allows you to employ others without having to contribute equal percentages for everyone.
- Businesses wanting to match employee contributions. Unlike a 401(k), the matching rules are simpler and mandatory.
Setup and administration
A SIMPLE IRA is easy to set up. You complete a short form with your chosen financial institution (bank or brokerage), notify employees, and begin operations. There is no Form 5500 annual filing (unlike a 401(k)), making compliance minimal.
Employers must file Form 5498-SIMPLE annually with the IRS and provide a copy to each employee, but this is routine.
Contribution limits
Employee contributions (2024): Up to $16,000 per year ($19,500 with catch-up at 50+).
Employer contributions: Matching (100% of the first 3% of salary) or 2% non-elective. In practice, most employers choose the matching formula, as it ties contributions to employee participation.
Withdrawal and tax rules
SIMPLE IRAs follow standard IRA withdrawal rules:
- Penalty-free withdrawals at 59½.
- 10% penalty (plus income tax) for withdrawals before 59½ (with exceptions).
- Required minimum distributions begin at age 73.
- All withdrawals are taxed as ordinary income.
One exception: there is a 25% early-withdrawal penalty (instead of 10%) if you withdraw within the first two years of opening the SIMPLE.

| Feature | SIMPLE | SEP IRA | 401(k) |
|---|---|---|---|
| Eligible employers | Up to 100 employees | Any size | Any size |
| Max employee contribution (2024) | $16,000 | None (not employee contributions) | $23,500 |

| Admin burden | Low | Very low | Moderate to high |
| Annual IRS filing | Form 5498-SIMPLE | No (if no employees) | Form 5500 (if balance > $250k) |
| Loan option | No | No | Yes (if plan allows) |
Changing or terminating
If an employer wants to switch to a 401(k) or SEP, or terminate a SIMPLE, there are rules about timing and notification. Generally, the employer must give employees 30 days’ notice.
