One of the most overlooked advantages of being self-employed is how much control you have over your retirement savings. The plans available to you are not just slightly better than what a typical employee gets through their company. For most self-employed people earning a decent income, the contribution limits are substantially higher, and the tax savings can be genuinely significant.
The challenge is that there are several plan options and the right one depends on factors that vary considerably from one freelancer to the next: how much you earn, whether you have employees, how old you are, and how much administrative complexity you are willing to manage. This guide walks through every meaningful option available in 2026, how they compare, and how to figure out which one makes sense for your situation.
Why Retirement Savings Matter Even More When You Are Self-Employed
When you work for a company, retirement contributions often happen automatically through payroll deduction, and employers commonly match a percentage of what you put in. When you work for yourself, none of that happens unless you set it up deliberately.
The tax argument for doing so is strong. Every dollar you contribute to a traditional SEP-IRA, Solo 401k, or SIMPLE IRA reduces your taxable income dollar for dollar, which lowers both your federal income tax and the income base used to calculate your self-employment tax. At a combined marginal rate of 30 to 40 percent, a $20,000 contribution translates to $6,000 to $8,000 in immediate tax savings before the investment even grows. That is a return no savings account or short-term investment can match in year one.
The Main Plans Available to Self-Employed People
There are five plan types worth understanding, and they serve meaningfully different situations.
SEP-IRA (Simplified Employee Pension): The most common choice for solo freelancers who want simplicity above all else. A SEP can generally be established as late as the due date of the employer’s tax return, including extensions, which allows the contribution decision to be made when the tax picture is clearer rather than months earlier. The SEP-IRA contribution limit for 2026 is the lesser of $72,000 or up to 25 percent of compensation or net self-employment earnings, with a $360,000 limit on compensation that can be used to factor the contribution. There is no employee deferral and no catch-up contribution for people over 50, which is the primary limitation compared to a Solo 401k. Virtue CPAsExpertHelp Blog
Solo 401k (One-Participant 401k): The most powerful option for owner-only businesses who want to maximize contributions, particularly at lower and moderate income levels. The owner can contribute both as employee and as employer, and that dual-contribution framework is what often makes the Solo 401k the most efficient savings vehicle for owner-only businesses. For 2026, the basic elective deferral limit is $24,500, the general catch-up limit for ages 50 and over is $8,000, and the higher catch-up limit for ages 60 through 63 is $11,250. Total contributions including both sides cannot exceed $72,000, or $80,000 with standard catch-up contributions. The plan must be established by December 31 of the year you want it to count for, unlike the SEP-IRA which can be opened after year-end. Virtue CPAsVirtue CPAs
SIMPLE IRA (Savings Incentive Match Plan for Employees): Designed for small businesses with up to 100 employees rather than solo operations. For 2026, employee contributions are capped at $17,000 with a catch-up contribution of $4,000 for those age 50 or older, and a higher catch-up of $5,250 for ages 60 through 63 under SECURE 2.0 rules. The employer contribution is mandatory, either a match or a nonelective contribution for all eligible employees. There is also a rollover constraint worth knowing: during the first two years of participation, a distribution from a SIMPLE IRA qualifies as a rollover only if it is transferred to another SIMPLE IRA, and early withdrawals during that period can trigger a 25 percent additional tax rather than the usual 10 percent.

Defined Benefit Plan: The most powerful tax shelter available to self-employed business owners, with actuarially determined contributions that can exceed $200,000 per year depending on age and income, far above what any defined contribution plan allows. A pension actuarially calculates what you need to contribute each year to fund a promised retirement benefit, which means older, higher-earning freelancers can shelter dramatically more income than any other plan permits. The trade-off is cost and complexity: these plans require an actuary to calculate contributions annually, administrative overhead is significant, and contributions are mandatory every year once the plan is in force. SmallBizHandbook
Traditional or Roth IRA: The contribution limit for 2026 is $7,000, or $8,000 if you are 50 or older. These accounts work best as a supplement to one of the higher-limit plans above rather than as a primary retirement vehicle, since the contribution room is modest by comparison. Our Roth IRA vs Traditional IRA guide covers how these fit alongside larger self-employed plans.

How the Contribution Gap Works at Different Income Levels
The most important practical comparison for most freelancers is between the SEP-IRA and Solo 401k, since those are the two plans they will realistically consider. The difference in how much you can contribute at the same income level is the main decision driver.
A concrete example makes this clear: if an individual at least age 50 made $40,000 as a sole proprietor, they would only be able to contribute 25 percent of their $40,000 in income, which comes to $10,000, in a SEP-IRA. In a Solo 401k, the same individual could make an employee deferral contribution of $32,500 plus a 25 percent employer contribution of $10,000 for a total deferral of $42,500, more than four times what the SEP-IRA allows at that income level.

That gap closes as income rises. Once you are earning enough that the employer-side contribution alone approaches the $72,000 ceiling without needing the employee deferral to fill it in, the difference between the two plans shrinks. But for most freelancers earning between $40,000 and $200,000, the Solo 401k allows meaningfully larger contributions at the same income level, which translates directly into more tax savings today and more compounding growth over time.
Who the SIMPLE IRA Is Actually For
The SIMPLE IRA exists for a specific use case that does not apply to most solo freelancers: a small business with employees that wants to offer a retirement benefit without the administrative burden of a full group 401k.
A SIMPLE IRA is not just a low-friction plan for the owner. It is a commitment to making annual contributions for staff under the applicable formula. Its strategic value is that it provides a meaningful employee benefit without requiring a full 401k administration setup. For a freelancer who has grown their business and brought on part-time or full-time staff, the SIMPLE IRA fills a real gap between the solo plans and a full corporate 401k. Virtue CPAs
The early withdrawal penalty structure is worth emphasizing again because it is genuinely unusual: withdrawals in the first two years of participation carry a 25 percent penalty rather than the standard 10 percent, which means this plan rewards a longer time horizon and punishes changes of plan shortly after setup.
When a Defined Benefit Plan Makes Sense
A defined benefit plan is worth taking seriously once you are earning well over $200,000 in net self-employment income annually and have already maxed out a Solo 401k or SEP-IRA. The actuarial contribution calculation can allow contributions far above the $72,000 ceiling that caps all defined contribution plans, and older business owners benefit the most because the formula assumes a shorter runway to retirement and therefore requires larger contributions to fund the target benefit.
The mandatory annual contribution is the main risk. If you have a bad year and cannot fund the required amount, you may need to amend the plan, which involves additional cost and IRS interaction. This makes defined benefit plans most appropriate for self-employed people with high, consistent income rather than those with significant year-to-year variability.
Some high earners combine a defined benefit plan with a Solo 401k, using the defined benefit plan to shelter the majority of income and the Solo 401k for the Roth deferral component that a defined benefit plan cannot provide. This combination requires careful actuarial coordination and is almost always best set up with a CPA or retirement plan specialist.
The Tax Mechanics Across Plan Types
All traditional contributions, whether to a SEP-IRA, Solo 401k, SIMPLE IRA, or defined benefit plan, reduce your taxable income in the year the contribution is made. For sole proprietors and partners, self-employed retirement plan contributions are based on a reduced-rate calculation that takes the self-employment tax adjustment into account rather than a simple 25 percent of net income, which is one of those areas where it makes sense to run the numbers with a CPA or plan provider before deciding how much to contribute.

The deduction appears on Schedule 1 of your Form 1040 rather than on Schedule C, but it reduces the same adjusted gross income figure that determines your income tax bracket, your ACA marketplace subsidy eligibility, and several other calculations that flow from your MAGI.
For the Roth option available in Solo 401k plans, contributions go in after tax with no current deduction, but all future growth and qualified withdrawals come out completely tax-free. This is particularly useful for younger freelancers who expect to be in a higher bracket in retirement, or for anyone who wants some portion of their retirement savings completely insulated from future tax rate changes.

The One Question That Narrows the Choice Quickly
Before comparing contribution limits and features, the most useful question to ask is whether you have any employees other than possibly a spouse. If the answer is yes, a Solo 401k is off the table, and your realistic options are a SEP-IRA, a SIMPLE IRA, or a full group 401k depending on how many employees you have and how formal a plan they need.
If you are solo, or you and your spouse are the only people in the business, the choice is almost always between a SEP-IRA and a Solo 401k, and the contribution comparison at your specific income level usually makes that decision clear. If you want simplicity and flexibility on timing, the SEP-IRA wins. If you want to maximize what you put away at your current income, particularly if you are under $200,000 in net earnings, the Solo 401k wins on contribution math in almost every scenario.
Frequently Asked Questions
Can I contribute to both a SEP-IRA and a Solo 401k in the same year?
Technically yes, but since both are defined contribution plans, the total combined contributions cannot exceed the $72,000 overall limit. Having both does not unlock additional room. The more common transition is from a SEP-IRA to a Solo 401k when the contribution advantage becomes clear, or maintaining a SEP for one business entity while running a Solo 401k for another separate operation.
What happens to my Solo 401k if I hire a full-time employee?
If your business grows beyond the point where a Solo 401k is eligible, you generally cannot continue contributing to it as a one-participant plan. At that point you would need to either roll the funds into an IRA or convert the plan into a full 401k that covers employees, which involves significantly more administration and cost. Accounting Portal
Can I start a retirement plan if I had a loss year?
You need net self-employment income to make contributions. If your Schedule C shows a net loss or zero profit, you cannot contribute to a SEP-IRA or Solo 401k for that year. A Roth IRA contribution also requires earned income. A loss year is a legitimate reason to skip a contribution rather than force one.
Is there a minimum contribution required each year?
For a SEP-IRA and Solo 401k, contributions are completely discretionary. You can contribute the maximum one year and nothing the next with no consequence. A SIMPLE IRA requires the employer contribution every year once established. A defined benefit plan also requires annual funding based on the actuarial calculation, which is the main reason it is reserved for people with consistent, high income.
Final Thoughts
The right retirement plan for a self-employed person is the one that fits both your current income and your capacity for administrative complexity. For most solo freelancers earning under $200,000 who want to maximize contributions without significant paperwork, the Solo 401k is the stronger tool, primarily because the employee deferral component allows meaningfully larger contributions at most income levels than a SEP-IRA alone. For freelancers who want simplicity and the flexibility to decide their contribution after year-end, the SEP-IRA delivers that with minimal overhead. For those who have grown their operation to include staff, the SIMPLE IRA bridges the gap before a full group 401k becomes necessary. And for high earners who have outgrown defined contribution limits, a defined benefit plan is one of the few remaining tools capable of sheltering large amounts of income from tax in a single year.
