One of the quieter costs of leaving traditional employment is losing the built-in retirement infrastructure that comes with it — no automatic payroll deduction, no employer match, no HR department nudging you toward enrollment. If you are self-employed, freelance, or run your own business, saving for retirement becomes your responsibility entirely, from choosing an account to actually funding it consistently. The good news is that the accounts available to self-employed people are often more generous than a standard employer 401(k), once you understand how to use them.
This guide walks through the main retirement account options for people without an employer plan, how much you can actually contribute, and how to build a savings habit that survives the unevenness of running your own business.
Why This Requires More Deliberate Planning
When you work for someone else, retirement saving is often semi-automatic: you set a contribution percentage once, it comes out of every paycheck, and an employer match sweetens the deal. Self-employment removes every part of that system. There is no default contribution, no match, and no one flagging it if you go a year without saving anything. On top of that, your income may vary significantly month to month, which makes a fixed contribution schedule harder to sustain than it would be for a salaried employee.
The result is that self-employed retirement savers need to actively choose an account, actively decide how much to contribute, and actively transfer the money — usually in irregular amounts tied to cash flow rather than a steady paycheck. None of this is complicated once set up, but it does not happen by default the way it does with a workplace plan.
SEP IRA
A Simplified Employee Pension IRA, or SEP IRA, is one of the most popular retirement accounts for self-employed individuals because of its simplicity and high contribution ceiling. As the employer, you contribute a percentage of your compensation or net self-employment earnings — up to 25 percent, capped at a dollar limit that is adjusted for inflation most years. There is no employee salary-deferral component; the entire contribution comes from the “employer” side, even when you are both the employer and the only employee.
The appeal of a SEP IRA is administrative simplicity: setup is quick, ongoing paperwork is minimal, and most major brokerages offer them with no account fees. The tradeoff is that contribution amounts are entirely tied to a percentage of income, so in a lower-earning year, your maximum contribution shrinks accordingly, and there is no separate employee-deferral bucket to fall back on the way there is with a solo 401(k). If you have any employees other than yourself, you are generally required to contribute the same percentage on their behalf, which is worth factoring in if you plan to hire.
Solo 401(k)
A Solo 401(k) — sometimes called a one-participant 401(k) — is generally the most flexible and often the highest-ceiling option for a self-employed person with no other employees. It lets you contribute in two separate capacities: as the “employee,” through a salary deferral, and as the “employer,” through a profit-sharing contribution based on a percentage of compensation. Combined, these two layers frequently allow you to save significantly more than a SEP IRA would at the same income level, particularly if your net self-employment income is moderate rather than very high.
At lower income levels, this structure gives Solo 401(k) plans a real edge over SEP IRAs: because the employee deferral is not tied to a percentage of income the way the employer contribution is, someone earning a modest income can still make a meaningful contribution through the deferral alone, something a SEP IRA does not allow. That gap narrows the higher your income climbs, and at high enough income levels, both accounts land in similar territory. A Roth option is available through many providers for the employee-deferral portion, letting you choose between pre-tax and after-tax treatment for at least part of your contribution.
Two administrative details matter here that do not apply to a SEP IRA: the plan itself generally must be established by the end of the calendar year in which you want to contribute, and employee deferrals typically need to be made by year-end as well, while the employer contribution can often follow later, up to your tax filing deadline including extensions. If you think a Solo 401(k) might fit, set it up well before December rather than waiting until tax season.
Traditional and Roth IRAs
Even with a SEP IRA or Solo 401(k) in place, you can generally still contribute to a Traditional or Roth IRA, subject to their own separate — and much lower — annual limits, and subject to income restrictions for Roth eligibility at higher earnings. These accounts are worth using either as your primary retirement vehicle when you are just starting out, and contribution amounts are modest, or as a supplemental account alongside a larger SEP IRA or Solo 401(k) once your income grows.
A Roth IRA in particular is worth considering if you expect to be in a similar or higher tax bracket in retirement than you are now, since qualified withdrawals in retirement are tax-free. A Traditional IRA offers an upfront tax deduction instead, which can be valuable in a high-earning year when reducing taxable income matters more.
SIMPLE IRA
A SIMPLE IRA is generally better suited to a small business with a handful of employees rather than a solo operator, because its contribution limits are meaningfully lower than a SEP IRA or Solo 401(k), and it typically requires the employer to make mandatory contributions on employees’ behalf, which becomes costly as headcount grows. It is easier to set up and administer than a full 401(k) plan, which is its main advantage if you expect to hire a small team but want to avoid the compliance overhead of a traditional employer 401(k).
How Much Should You Actually Be Saving
A common guideline suggests aiming to save somewhere between 15 and 20 percent of your income toward retirement when you do not have an employer match to supplement your contributions — higher than the roughly 10 to 15 percent often recommended for salaried workers, precisely because there is no employer contribution filling part of the gap. This is a general benchmark rather than a strict rule; your actual target depends on your age, how much you have already saved, your expected retirement age, and your broader financial goals.
Given irregular income, it often makes more sense to think in percentages rather than fixed dollar amounts. Setting aside a consistent percentage of every payment as it arrives — similar to how you might set aside a percentage for taxes — keeps retirement saving proportional to what you are actually earning, rather than becoming a fixed obligation that feels unmanageable in a slow month and underused in a strong one.
Building the Habit Without an Automatic Paycheck Deduction
The biggest practical challenge is not choosing the right account — it is actually funding it consistently without the automation a traditional payroll system provides. A few approaches make this easier. Set up an automatic transfer from your business or personal checking account into your retirement account on a recurring schedule, even if it is a modest amount, and treat it the same way you would treat a non-negotiable bill. Alternatively, if your income is highly variable, consider a percentage-based approach where you transfer a set percentage of every client payment into a designated retirement savings sub-account, then formally contribute that accumulated amount to your SEP IRA or Solo 401(k) on a quarterly or annual basis.
Because SEP IRA and Solo 401(k) profit-sharing contributions are typically due by your tax filing deadline (including extensions), some self-employed people use a strong year-end or tax-season lump sum contribution as their main savings mechanism, after seeing their full-year numbers and knowing exactly how much they can afford to set aside. This works, but it carries the risk of becoming an afterthought if the business has a rough year and cash is tight right when the contribution is due — which is why pairing it with smaller recurring transfers throughout the year tends to produce more consistent results.
Defined Benefit Plans for High Earners
If you are a high-earning solo consultant or business owner later in your career and want to save well beyond what a SEP IRA or Solo 401(k) allows, a defined benefit plan (sometimes called a cash balance plan) is worth exploring. Unlike the contribution-limit accounts above, a defined benefit plan is built around a target retirement benefit, and the allowable contribution is calculated actuarially based on your age, income, and years until retirement — which can allow six-figure annual contributions for someone in their 50s with high, consistent income. These plans require more administrative setup, typically an actuary and annual filings, and work best for established businesses with predictable income rather than early-stage freelancers still finding their footing. They are also less flexible year to year than a SEP IRA, since the contribution formula is largely fixed once the plan is established, so they suit business owners who can commit to consistent funding.
Common Mistakes to Avoid
A few patterns trip up self-employed savers repeatedly. The first is waiting until the business feels “stable enough” before opening any retirement account at all — a delay that often stretches years, quietly costing significant compounding growth in the process. The second is choosing an account based on what a friend or online forum recommends without checking whether it matches your income level and business structure; a SEP IRA and a Solo 401(k) can produce very different maximum contributions depending on how much you earn and how that income is structured.
A third mistake is treating retirement contributions as whatever is left over after every other expense, rather than as a planned percentage set aside proactively. Money that is only saved “if there’s extra” tends to disappear into business reinvestment or lifestyle creep instead. A fourth is missing plan-establishment deadlines — particularly relevant for a Solo 401(k), which generally must be opened before the end of the tax year you want it to apply to, unlike a SEP IRA, which can often be opened as late as your filing deadline. Missing that window can mean losing an entire year of tax-advantaged contribution room.
Working With a Tax Professional
Because contribution limits, deduction rules, and deadlines vary by account type and can change from year to year, it is worth reviewing your retirement plan with a CPA or financial advisor at least once, particularly when your income changes significantly, or you are deciding between a SEP IRA and a Solo 401(k) for the first time. This is also the point where entity structure matters: how you are taxed — as a sole proprietor, S-corp, or otherwise — affects exactly how your contribution limits are calculated, and a professional can help you avoid over- or under-contributing.
Final Thoughts
Losing access to an employer 401(k) does not mean losing access to strong retirement savings options — in many cases, the accounts available to self-employed people allow for higher contributions than a typical workplace plan. The real challenge is discipline rather than access: choosing an account that fits your income pattern, automating contributions wherever possible, and treating retirement saving as a fixed priority rather than something you get to eventually once the business is more established. The earlier you build that habit, the more time your contributions have to compound — and compounding, more than any single account choice, is what actually builds a comfortable retirement.
