Freelancer, contractor, or small business owner? You have powerful retirement options — often with higher limits than a regular 401(k). Here's exactly which plan fits your situation.

When you're self-employed, no employer is automatically putting money aside for your future. That means it's entirely on you — but it also means you have access to retirement plans that allow far higher contributions than a standard employee 401(k).
There are roughly 16 million self-employed Americans, including freelancers, gig workers, consultants, and small business owners. Many leave significant tax savings on the table by not using the right plan. Every dollar you contribute to a qualifying retirement account reduces your taxable self-employment income — a double win.
💡 Key insight: A self-employed person earning $150,000 can contribute up to $62,000 to a Solo 401(k) in 2026 — vs. just $23,500 in a regular employee 401(k). That's a massive tax advantage.
Best for: Self-employed individuals and business owners with no full-time employees (spouse may participate)
The Solo 401(k) — also called an Individual 401(k) or One-Participant 401(k) — is the most powerful retirement vehicle for self-employed people. You wear two hats: employee and employer. That means you can make contributions in both roles, stacking up to $72,000 in 2026.
How the contribution math works in 2026:
💡 Pro tip: At $100K net self-employment income, a Solo 401(k) lets you contribute $49,500 — nearly double what a SEP IRA allows at the same income level. See the comparison table below.
Best for: Self-employed individuals, sole proprietors, freelancers, and small business owners who want a simple plan — with or without employees
The SEP IRA is the simplest high-limit retirement plan available to self-employed individuals. You can open one in minutes, contribute up to $72,000 in 2026, and the paperwork is minimal. There's no annual filing requirement with the IRS.
The catch: your contribution rate must be the same percentage for you and any eligible employees. This makes SEP IRAs less attractive if you have employees — you're required to contribute the same percentage of their salary.
Best for: Small businesses with 1–100 employees who want to offer a retirement benefit without the complexity of a traditional 401(k)
SIMPLE stands for Savings Incentive Match Plan for Employees. Unlike a SEP, employees can make salary deferrals, making this feel more like a traditional 401(k). Employers are required to either match employee contributions up to 3% of salary or contribute a flat 2% for all eligible employees.
The 2026 contribution limit is $16,500 for employees (plus $3,500 catch-up if 50+). This is significantly lower than the Solo 401(k) or SEP IRA, but SIMPLE IRAs are an excellent middle ground for business owners who want to offer employees a real retirement benefit.
Best for: Anyone starting out, lower income earners, or as a supplement to a Solo 401(k) or SEP IRA
The standard IRA — Traditional or Roth — is available to anyone with earned income, including self-employed individuals. The 2026 contribution limit is $7,500 (under 50) or $8,600 (50+). While the limits are lower, IRAs offer flexibility and are a great place to start before setting up a more complex plan.
Roth IRA income limits for 2026: Phase-out begins at $150,000 for single filers and $236,000 for married filing jointly. If you earn above those thresholds, consider a "backdoor Roth IRA" — consult a tax advisor.

Open Roth IRA at Fidelity →⚠️ Watch the deadlines: A Solo 401(k) must be established by December 31 of the tax year. A SEP IRA can be opened as late as your tax filing deadline (including extensions — typically October 15). Don't miss the Solo 401(k) window if you want to maximize 2026 contributions.
Yes — in many cases, you can stack plans. For example, you can have a Solo 401(k) and a Roth IRA, as long as your total contributions don't exceed IRS limits for each account type. Some self-employed individuals also contribute to both a SEP IRA and a Roth IRA. Always verify with a tax professional, as the calculations can get complex.
High earners (typically $200K+ net income) who want to shelter even more income may consider a Defined Benefit (DB) Plan — essentially a private pension. Contribution limits can exceed $300,000 per year depending on your age and income. These plans are complex and expensive to administer, typically requiring an actuary. They're worth exploring with a CPA if you're in that income range.
The Solo 401(k) is almost always the best choice for a self-employed individual with no employees (other than a spouse). It offers the highest contribution limits of any plan available to solopreneurs — up to $72,000 in 2026 — plus a Roth option and loan provision.
For most self-employed individuals, yes — especially at lower income levels. At $100,000 in net self-employment income, a Solo 401(k) allows up to $49,500 in contributions vs. only $18,587 for a SEP IRA. The SEP IRA's main advantage is simplicity. If you want to maximize tax savings, the Solo 401(k) wins at almost every income level.
Yes — it's called a Solo 401(k) or Individual 401(k). It works the same way as a traditional employer 401(k) but is designed for business owners with no full-time employees (a spouse may participate). You act as both employee and employer and can make contributions in both capacities.
No. Contributions to a Solo 401(k) or SEP IRA reduce your federal income tax, but they don't reduce your self-employment tax (Social Security + Medicare). Self-employment tax is calculated on net earnings before retirement contributions. However, the tax deduction still saves you a significant amount at income tax rates.
You must establish a Solo 401(k) by December 31, 2026 to make contributions for the 2026 tax year. However, you can make the actual contribution itself until your tax filing deadline, including extensions (typically October 15, 2027 for 2026 taxes). This is different from a SEP IRA, which you can establish and fund up until the tax deadline.
Yes. SEP IRA contributions are made by you as the "employer" and do not affect your individual IRA contribution limits. You can contribute up to $72,000 to a SEP IRA and still make a separate $7,500 Roth IRA contribution in 2026 — subject to Roth income limits.
If you're using a Solo 401(k) and hire a full-time employee (someone who works 1,000+ hours per year), you'll need to convert your plan to a regular 401(k) or choose a different plan like a SIMPLE IRA or SEP IRA. Plan accordingly before hiring.
