Last updated: July 2026 · Contribution limits are set by the IRS and change each year. The 2026 figures below reflect the official limits; always confirm the current numbers before you fund an account.
For most self-employed savers, the solo 401(k) is the strongest retirement account, letting you contribute up to $72,000 in 2026 with a Roth option. Choose a SEP IRA if you want the simplest high-limit plan, a SIMPLE IRA if you have a few employees, and a Roth IRA alongside any of them for tax-free growth on the side.
Choosing a retirement account is the biggest money decision most freelancers put off. Every account promises tax advantages, yet they differ sharply in how much you can save, when you pay tax, and how much paperwork you take on. Pick the right one and you shelter tens of thousands of dollars a year. Pick the wrong one and you leave real money on the table.
This guide is the hub for our Retirement & Benefits cluster. It compares the retirement accounts that matter to the self-employed: the solo 401(k), the SEP IRA, the SIMPLE IRA, the traditional IRA, and the Roth IRA. You will see the 2026 contribution limits side by side, a plain review of who each account suits, and a simple decision path so you can stop guessing and open the right one.
There is no single best retirement account for everyone. The right choice depends on your income, whether you have employees, how much you want to save, and whether you value tax savings now or tax-free income later. By the end of this page you will know which account fits your situation, and which cluster guide to read next for the finer details.
Retirement accounts compared at a glance
Here is how the main options stack up on the numbers that decide most choices. All contribution limits are the official 2026 figures. The right column names the saver each account serves best, which is the fastest way to shortlist your pick before reading the detail below.
| Account | 2026 limit | Roth option | Employees allowed? | Best for |
|---|---|---|---|---|
| Solo 401(k) | Up to $72,000 | Yes | Owner + spouse only | Highest savings, one-person business |
| SEP IRA | Up to $72,000 | Rarely | Yes | Simple high-limit plan |
| SIMPLE IRA | $17,000 + employer | Limited | Yes (under 100) | Small teams with staff |
| Traditional IRA | $7,500 | No (pre-tax) | N/A (individual) | A tax deduction now |
| Roth IRA | $7,500 | Yes (all Roth) | N/A (individual) | Tax-free growth later |
The pattern is clear. The two workplace-style plans, the solo 401(k) and SEP IRA, allow far larger contributions than the IRAs. The IRAs are smaller but simpler and open to almost anyone with earned income. Most self-employed savers end up using one big plan plus a Roth IRA on the side.
Two questions that narrow your choice fast
Before the detail, two questions do most of the sorting. First, how much do you want to save each year? If the answer is more than the roughly $7,500 an IRA allows, you need a solo 401(k), a SEP IRA, or a SIMPLE IRA, because only those reach into the tens of thousands. If a few thousand a year is your reality right now, an IRA is enough to start.
Second, do you have employees? A solo 401(k) is only for a business with no full-time staff beyond a spouse, so hiring your first employee rules it out. A SEP IRA and a SIMPLE IRA both allow employees, but they require you to contribute for them too. Answer those two questions and you have usually narrowed five accounts down to one or two. Now the detail on each.
Solo 401(k)
Best for the highest savings in a one-person business. The solo 401(k), also called an individual 401(k), is the most powerful account a self-employed person with no employees can open. You contribute in two roles. As the employee you can defer up to $24,500 in 2026, and as the employer your business can add up to 25% of net earnings, for a combined ceiling of $72,000, or more with catch-up contributions after age 50.
Its edge is flexibility. A solo 401(k) offers both traditional and Roth contributions, and many plans allow participant loans, so you can borrow from your own balance in a pinch. The trade-off is a little more setup than an IRA and an annual Form 5500-EZ filing once your balance passes $250,000. For a profitable freelancer or one-person S-corp, no account shelters more.

SEP IRA
Best simple high-limit plan. The SEP IRA matches the solo 401(k) on the headline number, letting you contribute up to 25% of compensation to a cap of $72,000 in 2026, but it does it with far less paperwork. There is no annual filing to worry about, and setup at most brokerages takes minutes. For a self-employed saver who wants a big limit without the admin, it is the easy button.
The simplicity comes with limits. A SEP IRA is funded entirely by the employer, so there is no separate employee deferral, and that means you often cannot contribute as much at lower income as a solo 401(k) can. Most SEP IRAs are pre-tax only, with no built-in Roth option and no loan feature. If you have employees, you must contribute the same percentage of pay for each eligible one, which can get expensive.
Compare SEP vs solo 401(k) contributions →Skip it if: you want a Roth option, a loan feature, or the highest possible contribution at a modest income. A solo 401(k) usually wins there.
SIMPLE IRA
Best for a small business with a few employees. The SIMPLE IRA is built for the self-employed owner who has grown past a one-person shop but is not ready for a full 401(k). In 2026 you can defer up to $17,000 of your pay, with a required employer contribution on top, either a match of up to 3% or a flat 2% of compensation for each eligible worker. It suits businesses with fewer than 100 employees.
Its strength is easy team coverage. A SIMPLE IRA lets you offer staff a retirement benefit without the cost and complexity of a traditional 401(k). The weakness is the lower limit. Its $17,000 deferral trails the solo 401(k) and SEP IRA by a wide margin, so a high earner with no staff will save far less here than in the other plans. It is a people plan, not a maximum-savings plan.

Traditional IRA
Best for a straightforward tax deduction now. The traditional IRA is the simplest retirement account there is. Anyone with earned income can contribute up to $7,500 in 2026, plus a $1,100 catch-up at age 50 or older. Contributions may be tax-deductible depending on your income and whether you have a workplace plan, and your money grows tax-deferred until you withdraw it in retirement.
Think of it as a foundation, not a ceiling. The limit is small next to the self-employed plans, so it will not carry a serious saver alone. But it is effortless to open, requires no business paperwork, and gives you an upfront deduction that lowers this year’s tax bill. Many freelancers use a traditional IRA in a lean year and a bigger plan when income allows.
Estimate your tax savings →Skip it if: you can save more than $7,500 and want to shelter it. Pair it with, or replace it by, a solo 401(k) or SEP IRA.
Roth IRA
Best for tax-free growth in retirement. The Roth IRA flips the tax deal. You contribute up to $7,500 in 2026 with money you have already paid tax on, and in return every dollar of growth and every qualified withdrawal in retirement is tax-free. For a younger saver, or anyone who expects higher tax rates later, that trade is often the best deal in the entire tax code.
The catch is an income limit. In 2026 the ability to contribute directly phases out between $153,000 and $168,000 for single filers, and between $242,000 and $252,000 for married couples filing jointly. Earn above the top of your range and you cannot contribute directly, though a backdoor Roth strategy can still get you in. Most self-employed savers pair a Roth IRA with a bigger plan for the best of both worlds.
Check your Roth eligibility →Skip it if: your income sits above the phase-out and you want to avoid the backdoor route. A traditional IRA or a plan Roth may fit better.
2026 contribution limits, side by side
The numbers decide more than any feature list, so here they are in one place. These are the official 2026 limits, and they show at a glance why the workplace-style plans dominate for serious savers while the IRAs play a supporting role.
| Account | Employee / individual | Catch-up (50+) | Total 2026 limit |
|---|---|---|---|
| Solo 401(k) | $24,500 deferral | $8,000 ($11,250 at 60–63) | Up to $72,000 |
| SEP IRA | Employer only | None | Up to $72,000 |
| SIMPLE IRA | $17,000 deferral | $4,000 ($5,250 at 60–63) | Deferral + employer |
| Traditional IRA | $7,500 | $1,100 | $8,600 |
| Roth IRA | $7,500 | $1,100 | $8,600 |
Look at the gap. A solo 401(k) or SEP IRA can shelter nearly ten times what an IRA allows. That is the whole case for doing the extra setup of a self-employed plan once your income can support it. The IRAs remain useful, especially the Roth, but they work best as a companion to a larger account rather than the main event.

Start with your headcount, because it eliminates options fast. If you are a one-person business and want to save aggressively, the solo 401(k) is almost always the answer, with the SEP IRA as the lower-admin alternative. If you employ a small team, a SIMPLE IRA covers everyone without the weight of a full 401(k), and a SEP IRA works too if you can afford equal contributions for staff.
Then layer in tax strategy. If you want tax-free income in retirement, add a Roth IRA on the side, or use the Roth option inside a solo 401(k). If you want the biggest deduction today, lean on the pre-tax side of a solo 401(k) or a SEP IRA. Many self-employed savers run a two-account plan: a solo 401(k) or SEP IRA for the large tax-advantaged space, and a Roth IRA for tax-free growth. Match the accounts to your income and your team, open them before the relevant deadline, and let compounding do the rest.
Conclusion
Comparing retirement accounts comes down to three things: how much you want to save, whether you have employees, and when you want your tax break. For a one-person business that wants to save the most, the solo 401(k) wins, with the SEP IRA close behind for its simplicity. A SIMPLE IRA fits a small team, and the traditional and Roth IRAs round out any plan with a modest but valuable boost.
The best move is rarely a single account. Most self-employed savers pair a high-limit plan with a Roth IRA, capturing both a big deduction and tax-free growth. Decide which combination fits your income and your business, run your exact numbers, and open the accounts in time to count for this tax year. Whichever you choose, the sooner you start, the more the tax advantages compound in your favor.
