What a SEP IRA is
SEP stands for Simplified Employee Pension. A SEP IRA is a retirement account that lets self-employed individuals and small business owners save far more than a standard IRA allows, with relatively little paperwork.
It works much like a traditional IRA on the tax side: contributions are generally deductible, and the money grows tax-deferred until you withdraw it in retirement.
How it works
With a SEP IRA, the contribution comes from the business side. If you are self-employed, you contribute a percentage of your net business income to your own account. If you have employees, you generally must contribute the same percentage for them.
The contributions reduce taxable income now, and the account follows the same tax-deferred, eventually-taxed pattern as a traditional IRA.
Why the limits are so high
The headline appeal of a SEP IRA is its high contribution ceiling. You can contribute a substantial share of your net self-employment income, up to a cap set each year, which is many times the limit on a standard IRA.
That makes it a powerful tool for freelancers and business owners with strong income who want to shelter a large amount for retirement.
💡 Built for higher earners who are self-employed:Because the limit is tied to a percentage of business income, a SEP IRA rewards self-employed people with healthy profits who want to save aggressively with minimal admin.
Who it suits
A SEP IRA fits one-person businesses, freelancers, and contractors who want high contribution limits without the complexity of other plans. It is simpler to run than some alternatives, though it lacks features like employee salary deferrals and catch-up contributions.
For solo business owners weighing options, it is often compared with a solo 401(k), which can allow even larger contributions in some cases but involves more administration.
Frequently asked questions
Who can open a SEP IRA?
A SEP IRA is designed for self-employed individuals and small business owners. Freelancers, contractors, and one-person businesses commonly use them, and a business with employees can offer them too, with rules about contributing for staff.
How much can I contribute to a SEP IRA?
You can contribute a substantial percentage of your net self-employment income, up to a cap set each year, which is many times the limit on a standard IRA. Because the figures change, it is worth checking the current year’s limits.
What is the difference between a SEP IRA and a traditional IRA?
Both are tax-deferred, but a SEP IRA is funded from the business side and allows far higher contributions, making it suited to the self-employed. A traditional IRA has a much lower limit available to most workers with earned income.
SEP IRA or solo 401(k)?
Both suit the self-employed. A SEP IRA is simpler to set up and run, while a solo 401(k) can allow larger contributions in some situations and offers features like salary deferrals, but it involves more administration. The best fit depends on your income and preferences.
