Side-by-Side Comparison

SIMPLE IRA

Pros

+Employees can contribute too — up to $16,500 in 2026 ($20,000 if 50+)
+Employer match (up to 3%) or flat 2% contribution — employees love this
+Easy to set up and administer — minimal paperwork vs a 401(k)
+No annual filing requirements — no Form 5500 headaches
+Available to businesses with 100 or fewer employees

Cons

-Lower contribution limits than SEP IRA or Solo 401(k)
-Employer must contribute every year — either match or 2% flat, no skipping
-25% early withdrawal penalty if you leave within the first 2 years (not just 10%)
-No Roth option — all contributions are pre-tax only

Best For

Small businesses with employees who want a retirement benefit, owners who want to attract and retain talent, and businesses too small for a 401(k) but wanting employee participation.

SEP IRA

Pros

+High contribution limits — up to 25% of compensation or $69,000 in 2026
+100% employer-funded — simple, one decision per year
+No annual filing requirements — easiest plan to maintain
+Flexible contributions — contribute a lot in good years, nothing in lean years
+Can be set up and funded as late as your tax filing deadline (including extensions)

Cons

-Employees cannot make their own contributions — employer only
-Must give the same percentage to all eligible employees — gets expensive with staff
-No Roth option available
-No catch-up contributions for those 50+

Best For

Self-employed individuals and freelancers with no employees, small business owners who want maximum flexibility, and anyone who wants the simplest high-limit retirement plan.

Glen's Verdict

Former hedge fund manager, current index fund enthusiast

It depends entirely on whether you have employees. Solo with no staff? SEP IRA wins on contribution limits and flexibility — contribute up to $69K and skip years when business is slow. Have employees? SIMPLE IRA is better because employees can contribute their own money (they'll appreciate it), and your mandatory match is capped at 3%. With a SEP, you'd have to give every employee the same percentage you give yourself, which gets wildly expensive. Know your situation, pick accordingly.
