When you work for yourself, there's no HR department enrolling you in a 401(k), no employer match landing in your account each payday. Retirement saving is entirely on you — which is exactly why so many self-employed people put it off until their 40s or 50s, then panic. The good news: the retirement plans available to the self-employed are actually more generous than most employee plans. You just have to choose one and fund it.
The three main options — SEP IRA, Solo 401(k), and SIMPLE IRA — each suit different situations. The right choice depends on your income level, whether you have employees, and how much complexity you'll tolerate. Here's the honest breakdown.
Which Retirement Plan Is Best for Self-Employed People?
For most solo self-employed people earning a solid income, the Solo 401(k) wins. It lets you contribute both as employee and employer, with combined limits reaching $70,000+ per year (higher if you're over 50), and it allows Roth contributions and even loans against the balance in some plans. If your net self-employment income is above roughly $60,000-80,000 and you have no employees besides a spouse, it's hard to beat.
The SEP IRA is the simplest option and the best pick if you might hire employees soon or want minimal paperwork. You can contribute up to 25% of compensation (capped annually — check current IRS limits), setup takes minutes, and there's virtually no annual administration. The tradeoff: no Roth option, no catch-up contributions structured the same way, and if you do hire employees, you must contribute the same percentage for them as for yourself — which gets expensive fast.
The SIMPLE IRA fits a narrow niche: self-employed people with a few employees who want a middle ground. Contribution limits are lower than the other two, setup is easy, and there's a small mandatory employer contribution. It's rarely the best choice for a true solo operator.
The IRS guide for self-employed retirement plans lays out the current contribution limits and eligibility rules, which change most years — always verify before you contribute.
How Much Should You Actually Contribute?
Financial planners generally suggest 15-20% of income toward retirement, and the self-employed should aim for the higher end since there's no employer match padding the total. On $80,000 of net income, that's $12,000-16,000 a year — which sounds daunting until you remember the tax deduction. Contributions to a SEP IRA or traditional Solo 401(k) reduce your taxable income dollar for dollar, which at a 22% marginal rate turns a $12,000 contribution into roughly $9,360 out of pocket.
If cash flow is tight — and for many self-employed people it is — start smaller and automate. Even $300 a month started at 30 beats $1,000 a month started at 45, thanks to compounding. Set up automatic monthly transfers so saving happens before you can spend the money. You can increase contributions in good months; most plans allow flexible timing as long as you hit annual deadlines.
Quick decision guide
- Solo, higher income ($60k+), want max contributions and Roth option: Solo 401(k)
- Solo or may hire soon, want simplest setup: SEP IRA
- Have employees and want easy plan with modest limits: SIMPLE IRA
- Income varies wildly year to year: SEP IRA (contributions are flexible, skip bad years)
- Want to borrow from your retirement savings in emergencies: Solo 401(k) (loans allowed by many plans)
Common Mistakes Self-Employed Savers Make
The biggest mistake is waiting for a ‘good year’ to start. There's always a reason to delay — slow quarter, new equipment, tax bill — and the years slip by. Open the account now with whatever you can contribute; you can fund it more heavily later. SEP IRAs can even be opened and funded up until your tax filing deadline, giving you months after year-end to decide.
Second mistake: contributing but never investing. Money sitting in the account's cash sweep earning 0.5% isn't a retirement plan — it's a savings account with extra steps. Choose a simple diversified investment (a target-date fund matching your expected retirement year is a fine default) and let it ride. Third: forgetting that retirement contributions interact with your quarterly estimated taxes. Big deductible contributions lower your taxable income, which can reduce what you owe each quarter — coordinate with your tax planning, not against it. If taxes confuse you, our overview of taxes for the self-employed covers the essentials.
Setting One Up This Week
Opening any of these takes under an hour at major brokerages like Fidelity, Schwab, or Vanguard — all offer low-cost Solo 401(k) and SEP IRA options with no setup fees. You'll need your EIN (see EIN basics if you don't have one), and for a Solo 401(k) you'll adopt a plan document the brokerage provides. Fund it with an initial transfer, set up automatic contributions, pick your investments, and you're done. Future you — the one who gets to actually retire — says thanks.
Tax Angles Worth Knowing
Retirement contributions are one of the few levers self-employed people have to meaningfully cut their tax bill, so coordinate them with your overall tax picture. Traditional contributions reduce this year's taxable income — valuable in a high-earning year. Roth contributions (available in Solo 401(k)s and IRAs) give you no deduction now but tax-free withdrawals later — often smarter in lower-earning years or when you're young and in a low bracket.
Don't overlook the Saver's Credit either: lower-income filers can get a tax credit (not just a deduction) for retirement contributions, worth up to $1,000. And remember that as a self-employed person you can also deduct half your self-employment tax and fund an HSA if you have a qualifying high-deductible health plan — the HSA triples as retirement savings since contributions are deductible, growth is tax-free, and withdrawals for medical costs are tax-free at any age.

The Practical Takeaway
Solo and earning well? Open a Solo 401(k). Want simplicity or planning to hire? Go SEP IRA. Either way, contribute 15-20% if you can, automate it monthly, and actually invest the money instead of letting it sit in cash. The best retirement plan for the self-employed isn't the one with the highest limits on paper — it's the one you fund consistently for decades. Open the account this week.
