Self-Employed IRA Contribution Limits for 2026: SEP, SIMPLE, Solo 401(k), and Personal IRAs

In 2026 you may be eligible for several types of IRA-based retirement savings plans, each having their own annual limits. You could be eligible to participate in a Personal Traditional or Roth IRA, a SIMPLE IRA (salary contributions limited to $17,000 plus an additional employer contribution made to yourself) or SEP IRA (limited to 25% of your net earnings from self-employment, up to the dollar amount set by the IRS as the SEP cap for that year). A Solo 401(k) Plan is both an employee-deferred plan and a Profit Sharing plan where you are considered both an employee making salary deferrals and the employer providing profit sharing contributions. At lower income levels, it will allow you to reach a contribution ceiling similar to the SEP's. Which one is best suited for you largely depends on your income level and whether you have employees.

What are the self-employed IRA contribution limits for 2026?

For 2026 you can contribute to an IRA as self employed in four ways, and the two options you need to consider are how much will come from your employer (as defined by your business) and how much will come from you personally. Your personal traditional or roth ira contribution is limited by the personal IRA contribution limit and it will be added on top of which ever employer plan you choose to use.^[3] In terms of contributions made through your employer there is a flat dollar amount you elect out of your own pay when using a SIMPLE IRA,^[2] a SEP-IRA allows for a percentage based contribution and that contribution increases with income,^[1] and a Solo 401(k) contributes through both mechanisms. The stacking order for these plans would look like this:

Two ways to make this table friendlier than it appears are as follows: (1) The personal IRA layer is stacked on top of any retirement plan provided by an employer. Therefore, contributing to a SEP will not consume your available Roth IRA contribution space. However, if you have been actively participating in an employer-sponsored plan, the ability to deduct contributions made into your traditional IRA may be phased out at higher income levels. (2) In the case of self-employment income, "compensation" refers to net earnings from self-employment after accounting for the self-employment tax adjustment. Thus, the behavior of 25% under the SEP will mirror that of 20%. IRS Publication 560 provides step-by-step instructions for calculating compensation.

How does income level decide the winner?

The percentage-based plans (SEP, the employer half of a solo 401(k)) reward high earners. The deferral-based plans (SIMPLE, the employee half of a solo 401(k)) reward everyone else, because a flat dollar deferral is worth more at modest incomes.

As a rough map:

• Under about $90,000 net: SIMPLE IRA generally provides the greatest value in dollars vs. hassle. See the full SIMPLE limits.
• Above that, no employees: you will have one of two options, Solo 401(k) or SEP. The Solo 401(k) provides more than the other option at any given level of income (percentage in addition to deferral), however there is a slight additional amount of paperwork. You can open and fund your SEP as late as when filing taxes and fund it retroactively if needed.
• Any income, with employees: percentages are bad when you have employees. A lot of that money goes to the staff because what you give yourself will ultimately end up going to them as well. The math behind this can be found in SEP IRA vs. SIMPLE IRA.

What rules do self-employed savers miss?

You may miss the SIMPLE IRA's exclusive-plan rule when you're self-employed. The SIMPLE IRA requires that if any contributions are made to a SIMPLE plan in a given year, this must be your only employer-sponsored plan for that year. Therefore, you cannot have both a SEP and a SIMPLE (or a solo 401(k)) at the same time. Additionally, there is timing involved with opening a new SIMPLE plan as well. To qualify for contributions for the current year, a SIMPLE must be established on or before October 1 of that year. However, SEPs can be started and funded at any time until your filing deadline (including extension deadlines).^[1] In addition to these restrictions, many individuals also overlook some smaller but still significant details:

• Deadlines differ: you may make different deadline decisions regarding SEP contributions. You can decide about your contribution and deposit it in conjunction with filing. SIMPLE deferrals must run through actual payroll (or draws) throughout the year.
• Roth options: personal IRAs have always had Roths. SIMPLE IRAs allow Roth deferrals since SECURE 2.0, while SEPs remain effectively pre-tax at most custodians.
• State mandates: any state-mandated program such as CalSavers, that requires employers to provide retirement savings options for their employees, will be satisfied if an employer has established one of the above-listed types of employer plans (e.g., SEP, SIMPLE or a solo 401(k)) once you have employees. See the CalSavers employer guide.
• Deduction phase-outs: active participation in an employer-sponsored retirement plan may cause you to have a reduced deduction on your traditional IRA contribution based upon your income level. The IRS sets income limitations for Roth IRA eligibility.

How much can a solo 401(k) hold compared to a SEP or SIMPLE?

You can put the most money in a Solo 401(k) of any self-employment plan at your income level because you are able to stack contributions from both of the other contribution methods (SEP and SIMPLE) that the IRA based plans treat separately. As an employee, you defer compensation like a SIMPLE participant but at a higher limit, and as the employer, you add up to 25% of your compensation like a SEP but still under the same annual dollar amount as for the SEP. For paper work, a Solo 401(k) does require a formal plan document, and when it gets too big it will need to file annually with the IRS which SEPs or SIMPLEs do not have to do. If you make less than the amount that would put you near the ceiling, then stacking gives you bigger benefits than if you were doing a SEP. When you get near the ceiling then using an SEP is better due to much less paperwork requirements.

What should you do in practice?

Most self-employees are happy with an automatic 2-tiered approach: max out the personal IRA every year, then add the employer plan, SIMPLE if your net earnings from your business are below about $90,000 per year, a solo 401(k) or SEP Plan if they are above that. Once you have hired one employee (W-2), go back and evaluate again. This will be when the SIMPLE IRA's fixed 3% employer cost normally wins over all other options based on percentages, and this is also the point at which IRAPilot can help guide you through process: It will create the necessary documents and notifications for the plan and show you how to enter payroll information into each of your accounts (self-matched contributions and deferral amounts) along with tracking each required deposit date.

The Bottom Line

In 2026 a self employed individual is able to stack a personal IRA on top of one employer plan. The SEP gives up to 25% of pay (which would be approximately 20% of net earnings). The SIMPLE gives a flat $17,000 deferral plus the amount they match themselves. Finally, if they choose the solo 401(k) plan, it combines both of these options for the maximum ceiling allowed. Choose the SIMPLE below approximately $90,000 of net earnings or a solo 401(k) or SEP option above that, then go back when you hire your first employee, because at that point the SIMPLE will generally outperform due to its capped cost.
