How Employer Contributions Work
Employers must choose one of two contribution options each year:
Option 1: Matching Contributions (Most Common)
Dollar-for-dollar match of employee contributions up to 3% of compensation.
| Employee Salary | Employee Contributes (6%) | Employer Match (3%) | Total Annual Savings |
|---|---|---|---|
| $40,000 | $2,400 | $1,200 | $3,600 |
| $60,000 | $3,600 | $1,800 | $5,400 |
| $80,000 | $4,800 | $2,400 | $7,200 |
| $100,000 | $6,000 | $3,000 | $9,000 |
Employers can reduce the match to as low as 1% in 2 out of every 5 years.
Option 2: 2% Non-Elective Contribution
Employer contributes 2% of each eligible employee’s pay, regardless of whether they contribute.
| Employee Salary | Employer Contribution (2%) |
|---|---|
| $40,000 | $800 |
| $60,000 | $1,200 |
| $80,000 | $1,600 |
| $100,000 | $2,000 |
Maximum compensation considered: $350,000 (so max 2% contribution = $7,000).

Key SIMPLE IRA Rules
Eligibility
| Requirement | Detail |
|---|---|
| Business size | 100 or fewer employees |
| Other plans | Cannot maintain another retirement plan |
| Employee eligibility | Earned $5,000+ in any 2 prior years AND expects $5,000+ this year |
| Employer deadline | Must set up by October 1 for current year |
Withdrawals
| Situation | Tax Treatment | Penalty |
|---|---|---|
| After age 59½ | Taxed as ordinary income | None |
| Before 59½ (after 2 years in plan) | Taxed as ordinary income | 10% early withdrawal penalty |
| Before 59½ (within first 2 years) | Taxed as ordinary income | 25% early withdrawal penalty |
| Rollover to IRA (after 2 years) | No tax | None |
| Rollover to IRA (within 2 years) | No tax | Only to another SIMPLE IRA |
Important: The 25% penalty (instead of 10%) during the first 2 years is a unique and harsh SIMPLE IRA rule. Avoid withdrawals in the first 2 years.
Required Minimum Distributions
Like traditional IRAs, SIMPLE IRAs require RMDs starting at age 73.
Advantages of a SIMPLE IRA
- Easy to set up and maintain — less paperwork than a 401(k)
- No annual filing — no Form 5500 required
- Guaranteed employer contribution — employees always get match or 2%
- Immediate vesting — all contributions (employee and employer) are immediately yours
- Lower costs — no discrimination testing, simpler administration
Disadvantages
- Lower contribution limits than 401(k) ($16,500 vs. $23,500)
- No Roth option — all contributions are pre-tax
- No loans — unlike 401(k)s, SIMPLE IRAs don’t allow plan loans
- 25% early withdrawal penalty in first 2 years
- Required employer contributions — employer must contribute every year
- October 1 setup deadline — can’t establish mid-year for current tax year
Who Should Use a SIMPLE IRA?
| Business Type | SIMPLE IRA Good Fit? | Better Alternative |
|---|---|---|
| Small business (5-50 employees) | Yes | Consider 401(k) if higher limits needed |
| Solo freelancer | Maybe | Solo 401(k) (higher limits + Roth) |
| Business wanting simplicity | Yes | |
| High-earning self-employed | No | SEP IRA (up to $70K) |
| Business wanting Roth option | No | 401(k) with Roth |

- Easiest plan to maintain — no annual filing, no discrimination testing
- Watch the 2-year rule — 25% penalty on early withdrawals in the first 2 years
