Finding a retirement plan that fits a small business budget isn’t always easy. Many owners want to help their employees save for the future but don’t have the time or resources to manage a complex 401k setup. A SIMPLE IRA can be a practical middle ground.
A SIMPLE IRA, or Savings Incentive Match Plan for Employees, is built for businesses with 100 or fewer employees. It keeps things simple — employees can save through pre-tax contributions, and employers must make annual contributions.
Read on to know how a SIMPLE IRA works, who qualifies, 2025 contribution limits, its main benefits and drawbacks, and how it compares with other small business retirement plans like the SEP IRA and Solo 401k.

What Is a SIMPLE IRA?
A SIMPLE IRA, short for Savings Incentive Match Plan for Employees, is a retirement plan designed for small businesses with 100 or fewer employees. It gives business owners a straightforward way to help their team save for retirement without the high setup or administrative costs of a traditional 401k.
Unlike other business retirement plans such as the SEP IRA or Solo 401k, which are often more favorable to the business owner, a SIMPLE IRA is designed mainly to benefit employees. Workers can make contributions using pre-tax dollars, and employers are required to make contributions for every eligible employee each year.
How a SIMPLE IRA Works
A SIMPLE IRA helps employees save for retirement through automatic payroll contributions, with employers making mandatory contributions each year. It’s straightforward to run and doesn’t require complex filings or high administrative costs.
Employee contributions are made with pre-tax dollars, which means they reduce taxable income for the year. These contributions are still subject to Social Security and Medicare taxes but excluded from federal income tax.
Although contribution limits are lower than those of a 401k, every eligible employee receives employer contributions—an advantage that many small business plans don’t guarantee.
Employer Contribution Options
Employers must contribute each year and can choose between two contribution methods:
✅ 2% Nonelective Contribution
Employers contribute 2% of an employee’s compensation, even if the employee doesn’t contribute to the plan.
✏️ Hypothetical Example: If an employee earns $100,000, the employer contributes $2,000 to their SIMPLE IRA.
✅ 3% Matching Contribution
Employers match employee contributions up to 3% of their compensation. Employees must contribute to receive this match.
✏️ Hypothetical Example: If an employee earning $100,000 contributes $3,000, the employer adds another $3,000.
📝 Note: Employers must make contributions every year. However, the match can be temporarily reduced to 1% for up to two out of five years with proper notice. The 2% nonelective option remains available during those years.
Who Is Eligible to Receive a SIMPLE IRA
A SIMPLE IRA is designed for small businesses and their employees. Both employers and employees must meet certain requirements to participate.
✅ For Employers
Any business with 100 or fewer employees can set up a SIMPLE IRA. The business cannot maintain another retirement plan, such as a SEP IRA, Solo 401k, or Traditional 401k, at the same time.
If the company later grows beyond 100 employees, it can continue the SIMPLE IRA for up to two additional years. After that, if the employee count remains above 100, the plan must be discontinued or converted to another eligible retirement plan.
✅ For Employees
Any employee who earned at least $5,000 in any of the two previous years and expects to earn at least $5,000 in the current year is eligible to receive employer contributions.
Employers can choose to lower or remove the $5,000 income requirement, which can make the plan more inclusive for newer or part-time workers.
SIMPLE IRA Contribution Limits
For 2025, employees can contribute up to $16,500 to a SIMPLE IRA. Those aged 50 and older can make an additional catch-up contribution of $3,500, bringing the total to $20,000.
Some SIMPLE IRA plans qualify for higher contribution thresholds under SECURE 2.0. Eligible employees may defer up to $17,600 in 2025. Those aged 60 to 63 can take advantage of a special “super” catch-up contribution of $5,250.
Comparison with a 401k
A 401k plan has higher limits — $23,500 for 2025, with a $7,500 catch-up for those aged 50 and above (total $31,000).
While the SIMPLE IRA has lower contribution limits, it stands out because employer contributions are mandatory. In contrast, 401k employer contributions are usually optional, unless the plan is designed as a safe harbor 401k.
📝 Note: Even with lower limits, a SIMPLE IRA can still be a strong fit for small businesses that value ease of setup and guaranteed employer contributions.
SIMPLE IRA Benefits and Downsides
A SIMPLE IRA can be a practical option for small businesses that want to provide retirement benefits without managing a complex or costly plan. Both employers and employees gain advantages, but there are trade-offs to consider.
For Employers
A SIMPLE IRA offers an easy and affordable way to help employees save for retirement. It’s less expensive and easier to manage than a traditional 401k, making it appealing for small companies with limited administrative resources.
Employer contributions are tax deductible, which can help reduce the business’s taxable income each year.
❌ Potential Drawbacks
Employers must make contributions annually, regardless of business performance. This requirement can be challenging during years with lower revenue.
Another limitation is that employers cannot save as much for their own retirement compared to higher-limit plans such as a SEP IRA or Solo 401k.
For Employees
Employees benefit from mandatory employer contributions, and those funds are immediately vested, meaning they fully own the money as soon as it’s deposited.
Employee contributions are excluded from taxable wages for income tax purposes, allowing them to save more efficiently. They can also contribute to an IRA in the same year, as long as they meet IRA eligibility rules.
Under SECURE 2.0, some plans may also offer a Roth SIMPLE IRA option, letting employees contribute after-tax money for potentially tax-free withdrawals in retirement.
SIMPLE IRA Withdrawal Rules
Withdrawals from a SIMPLE IRA follow similar rules to most other retirement plans. The standard age for penalty-free withdrawals is 59½.
Taking money out before age 59½ triggers a 10% early withdrawal penalty, in addition to regular income taxes on the amount withdrawn.
If the SIMPLE IRA is less than two years old, the early withdrawal penalty increases to 25%. This higher penalty is meant to discourage short-term use of retirement savings.
Qualified Withdrawals
Withdrawals made after age 59½ are penalty-free, though pre-tax contributions and earnings are still taxed as ordinary income.
If the plan includes Roth SIMPLE contributions, those follow Roth IRA rules, meaning qualified Roth withdrawals can be tax-free.
Required Minimum Distributions (RMD)
Like traditional IRAs, SIMPLE IRAs require participants to begin required minimum distributions (RMDs) at age 73.
Failing to take an RMD can result in a 25% excise tax on the amount not withdrawn. If the mistake is corrected promptly, that penalty can drop to 10%.
RMD amounts are calculated using the IRS life expectancy tables, which determine how much must be withdrawn each year.
📝 Note: Even if you’re still working, RMDs from a SIMPLE IRA must begin once you reach the required age, unlike certain employer-sponsored 401k plans that may allow deferral.
SIMPLE IRA vs SEP IRA vs Solo 401k
For self-employed professionals or small business owners, choosing between a SIMPLE IRA, SEP IRA, or Solo 401k usually comes down to business size and contribution goals.
✅ Solo 401k
A Solo 401k can offer the highest flexibility and tax advantages for those with no full-time employees. Contribution limits reach up to $70,000 in 2025, with both pre-tax and Roth options available. It also allows investing in a wide range of assets, as long as you stay within IRS rules on prohibited transactions and collectibles. The main limitation is eligibility—your business cannot have full-time W-2 employees working more than 1,000 hours a year.
✅ SEP IRA
A SEP IRA may suit small businesses with just a few full-time employees. It shares the same overall annual additions limit as the Solo 401k ($70,000 for 2025) and can also include Roth contributions if the employer offers them under SECURE 2.0. However, there’s a trade-off: employer contributions must be made at the same percentage rate for all eligible employees.
✏️ Hypothetical Example:
If an owner contributes 20% of their compensation to their SEP IRA, they must also contribute 20% of each employee’s compensation to their SEP IRAs. This setup can become costly for companies with many employees.
✅ SIMPLE IRA
A SIMPLE IRA can be a practical choice for businesses that want to offer a retirement plan to multiple employees without dealing with heavy administrative requirements or high costs. It’s often considered the middle ground between an IRA and a 401k—simpler to manage than a full 401k, yet more inclusive than a Solo 401k or SEP IRA.
Wrapping Up
A SIMPLE IRA can be a good option if you want an easy way to save for retirement and help your employees do the same. It’s usually less expensive to maintain than a 401k and doesn’t require much ongoing paperwork. Both you and your employees can make contributions, though the annual limits are lower than other business retirement plans.
If you don’t have full-time employees, a Solo 401k could be more flexible since it allows higher contributions. For businesses with just a few employees, a SEP IRA might be simpler.
Before deciding, take time to review your income, business setup, and long-term goals. You can also talk to a tax or financial professional to see which plan best fits your situation.
