SIMPLE IRA for Small Business Owners in 2027

Picture a six-person physical therapy clinic. The owner wants to offer a retirement benefit, partly to keep good staff and partly to save for herself. A provider hands her a 401(k) proposal with setup fees, an annual administration contract, and a paragraph about nondiscrimination testing she has to read three times. For a business that size, a SIMPLE IRA for small business owners is often the better fit, and it rarely gets pitched first.

What a SIMPLE IRA Is

A SIMPLE IRA is a workplace plan for employers with 100 or fewer employees. Employees choose to defer part of their pay, and the employer adds money in one of two ways. It can match employee deferrals dollar for dollar up to 3% of pay, or it can contribute a flat 2% of pay for every eligible employee whether they save or not. The IRS overview of SIMPLE IRA plans covers the full eligibility rules.

The appeal is in what’s missing. There is no annual Form 5500 filing and no nondiscrimination testing, and each employee’s money sits in an IRA at a financial institution instead of a plan trust the owner has to oversee.

Why This Matters Now

The limits went up for 2026. According to the IRS announcement of the 2026 limits, employees can defer $17,000 into a SIMPLE IRA. SECURE 2.0 also created a higher tier, $18,100 for 2026, that generally applies automatically to employers with 25 or fewer employees. Workers age 60 through 63 get a larger catch-up of $5,250.

Timing matters too. A new SIMPLE IRA generally has to be set up by October 1 to count for the current year, and employees get a 60-day election window before each plan year starts. That makes fall the season when a January 1 plan gets built.

A Practical Example

Back to the clinic. Assume the owner runs it as an S corporation and pays herself a $120,000 salary. The five other employees earn a combined $300,000.

With a 3% match, her worst-case cost for staff is $9,000 a year, and that only happens if every employee defers at least 3%. Her own 2026 savings would look like this:

• $18,100 in her own deferrals (the higher tier, since she has fewer than 26 employees)
• $3,600 in matching money on her $120,000 salary
• $21,700 total

A 401(k) could let her put away more, since the 2026 401(k) deferral limit alone is $24,500 before any employer money. The real question is whether the extra room is worth the extra cost and paperwork. For many owners at this income level, the answer is no.

Who This Affects Most

SIMPLE IRAs fit best for businesses with roughly 2 to 25 employees, owners who want to offer a real benefit without a compliance project, and owners whose personal savings goal is closer to $20,000 a year than $60,000. Small medical and dental offices, trade businesses, and professional service firms often land right in this range.

The Tradeoff

The simplicity comes with strings attached.

• Lower ceiling. Owners who want to shelter $40,000 or more a year will outgrow it quickly.
• Exclusive plan rule. You generally can’t maintain a SIMPLE IRA and another retirement plan for the same year.
• Immediate vesting. Every dollar you contribute belongs to the employee the day it lands, even if they leave in March.
• Two-year rule. An employee who withdraws in the first two years of participation can owe a 25% additional tax instead of the usual 10%.

Immediate vesting bothers some owners more than the limits do. In my view it’s the wrong thing to fixate on. A 3% match on a $45,000 salary is $1,350, and that is the entire exposure for that employee for the year.

A Strategic Angle

A SIMPLE IRA doesn’t have to be permanent. SECURE 2.0 made it possible to replace a SIMPLE IRA with a safe harbor 401(k) partway through a year, so a growing business can start small and step up once profits and headcount justify it. Picking the plan that fits this year’s numbers, rather than the plan you might need in five years, keeps more cash in the business while it grows.

One Step to Take This Month

Pull last year’s W-2 totals and count the employees who earned at least $5,000. Multiply their combined pay by 3% to find your maximum match cost, then set that number next to your own savings goal. If your goal fits under the SIMPLE limits and the match cost is comfortable, this plan deserves a serious look before next year’s election window opens.
