Best Retirement Account Options for Self-Employed People

Being self-employed gives you freedom over your work—but it also means no built-in 401(k) or employer match. If you want retirement savings, you have to create your own system.

The good news: self-employed people actually have some of the most flexible and powerful retirement account options available. The challenge is choosing among them.

This guide walks through the main retirement account options for self-employed people, how they work, and the trade-offs to think about—so you can see what might fit your situation.

The main retirement account options for self-employed

Most self-employed people end up looking at some mix of:

• Traditional or Roth IRA
• SEP IRA
• Solo 401(k) (also called individual or one-participant 401(k))
• SIMPLE IRA
• Less common: defined benefit / cash balance plan

Here’s a quick comparison before we dive deeper:

Exact contribution limits and rules change over time and depend on your income and structure (sole prop, LLC, S-corp, etc.), so treat ranges as directional, not precise numbers.

Step one: understand the basic tax choices

When you save for retirement, you’re usually choosing between two basic tax setups:

1. Pre-tax (traditional) accounts

   • Contributions may be tax-deductible now
   • Money grows tax-deferred
   • You pay ordinary income tax when you withdraw in retirement

2. After-tax (Roth) accounts

   • Contributions use after-tax dollars (no deduction now)
   • Money grows tax-free
   • Qualified withdrawals in retirement are tax-free

Self-employed plans can offer:

• Traditional-only (SEP IRA, many SIMPLE IRAs)
• Roth-only (rare on its own)
• Both traditional and Roth options (common with solo 401(k)s)

Which is better for you depends heavily on things like:

• Your current tax bracket vs. expected bracket in retirement
• How much flexibility you want later (tax-free income, required distributions, etc.)
• How long your money has to grow

You don’t have to pick “team Roth” or “team traditional” forever. Many people use a mix over time.

Option 1: Traditional and Roth IRAs

Almost anyone with earned income can open an IRA (Individual Retirement Account), even if you only have a small side business.

How IRAs work

• Opened through a bank, brokerage, or robo-advisor
• You choose between:
  • Traditional IRA – possibly tax-deductible contributions now, taxed later
  • Roth IRA – no deduction now, tax-free later (if rules are followed)
• Contribution limits are lower than self-employed plans, but still meaningful
• Investment choices are usually broad: stocks, bonds, funds, etc.

Whether your traditional IRA contribution is tax-deductible may depend on:

• Your income
• Whether you (or a spouse) are covered by a workplace plan
• Tax law in the year you contribute

Roth IRA contributions are limited or phased out at higher income levels. That doesn’t affect your eligibility for other plans (like SEP or solo 401(k)); it only affects Roth IRA itself.

When IRAs tend to be a fit

IRAs are often useful if:

• You’re just starting self-employment or have low/variable income
• You want something simple, widely available, and easy to manage
• You already max out other plans and still want to save more in a tax-advantaged account (within IRS rules)

Even high earners sometimes use IRA strategies (like non-deductible contributions and Roth conversions) but those get into more complex territory where individual tax advice is usually important.

Option 2: SEP IRA (Simplified Employee Pension)

A SEP IRA is a retirement plan designed specifically for self-employed people and small businesses.

Key features of a SEP IRA

• Funded with employer contributions only
  • When you’re self-employed, you’re both employer and employee
• Contribution is a percentage of your net self-employment income or wages
• Contributions are generally tax-deductible to the business
• Easy to set up and maintain compared with 401(k)s
• You must contribute the same percentage to eligible employees as you do for yourself, if you have employees

So if you contribute, say, 10% of your eligible compensation to your own SEP, you often need to contribute 10% for each eligible employee as well. That can be generous—or expensive—depending on your situation.

When SEPs tend to be a fit

A SEP IRA often works best if:

• You’re self-employed with no employees, or
• You’re comfortable contributing for employees at the same rate as for yourself
• Your income is sometimes high, and you want the potential to save significantly in high-income years
• You want something simpler than a 401(k) with fewer formal paperwork requirements

One limitation: SEPs are traditional-only. There’s no built-in Roth option, though people sometimes use Roth conversions later if that fits their tax planning.

Option 3: Solo 401(k) (Individual 401(k))

A solo 401(k) is a 401(k) plan designed for a business owner with no employees other than a spouse.

This is one of the most powerful tools available to self-employed people.

Who can use a solo 401(k)?

• Self-employed individuals with no common-law employees
• That includes sole proprietors, freelancers, single-member LLCs, and often owners of corporations
• Your spouse can also participate if they work in the business

If you hire non-spouse employees who meet eligibility rules, you may have to convert to a full 401(k) or adopt a different plan.

How solo 401(k)s work

They have two layers of contributions:

1. Employee contribution (elective deferral)

   • You, as the “employee,” can contribute up to a set limit each year, across all 401(k)s you have
   • This can usually be traditional (pre-tax) or Roth if the plan allows

2. Employer contribution

   • Your business can contribute a percentage of your compensation (similar to SEP logic)
   • These are pre-tax, not Roth

Because you’re wearing both hats (employee + employer), your total potential contribution can be much higher than with an IRA, especially at moderate to high income levels.

Why some self-employed people like solo 401(k)s

• Higher savings potential at many income levels compared with a SEP or IRA
• Possible Roth option for employee contributions
• Often allows loans from the plan, depending on the provider and current rules
• Flexibility to adjust contributions based on your income year to year

More moving parts, though:

• Typically requires formal plan documents
• May require additional filings once the plan grows above certain asset sizes
• Contribution amounts and deadlines can be more nuanced

For people with no employees and meaningful self-employment income, a solo 401(k) is often one of the strongest options to at least explore.

Option 4: SIMPLE IRA (Savings Incentive Match Plan for Employees)

A SIMPLE IRA is designed for small businesses, including self-employed people with a few employees, who want a retirement plan that’s easier than a full 401(k).

Key traits of a SIMPLE IRA

• You and your employees can make salary deferral contributions (like a 401(k) but with lower limits)
• The employer (you) generally must:
  • Match contributions up to a set percentage of pay, or
  • Make a fixed contribution for all eligible employees
• Plan rules are more straightforward and less expensive to administer than a standard 401(k)
• Many SIMPLE IRAs are traditional-only; Roth options are less common (but evolving)

When SIMPLE IRAs tend to be a fit

They often work well if:

• You’re self-employed with a few employees and want:
  • Something simpler and cheaper than a standard 401(k)
  • A way to offer employees a retirement benefit without heavy admin
• You’re okay with mandatory employer contributions each year (in one form or another), regardless of profits

Compared with a solo 401(k), SIMPLE IRAs usually:

• Have lower contribution limits
• Are availability-friendly for businesses with employees
• Are simpler but less flexible

Option 5: Defined benefit or cash balance plans

At the more complex end are defined benefit or cash balance plans.

These are pension-style plans that aim to provide a promised benefit in the future, which determines how much you can contribute now.

Why some self-employed people use them

They can allow very large, tax-deductible contributions, especially for:

• High earners
• People who are older and started saving later
• Professionals (doctors, lawyers, consultants) with strong, stable income

But they come with:

• Complex rules and required annual calculations
• Ongoing funding obligations—you can’t just stop and start as casually as with other plans
• The need for specialized professionals to set up and maintain them

This is usually not a beginner move. It’s more common for people who are already maxing other plans and need additional, structured savings.

How having employees changes your options

Whether you have employees—and how many—matters a lot.

If you have no employees (just you, maybe your spouse)

You can usually choose among:

• Traditional/Roth IRAs
• SEP IRA
• Solo 401(k)
• Defined benefit plan (less common, more complex)

In this scenario, solo 401(k) and SEP IRA are often the main contenders if you want to save more than an IRA alone allows.

If you have employees

Your landscape shifts:

• Solo 401(k) is generally off the table once certain employees qualify
• SEP IRA is possible, but:
  • You must contribute the same percentage for eligible employees as for yourself
• SIMPLE IRA can work for small teams that want an easier setup than a full 401(k)
• A traditional 401(k) or safe harbor 401(k) could also be options, but they come with more complexity and cost

The key variable here:
Are you willing and able to fund contributions for employees, and do you want your plan to double as an employee benefit?

Key variables that shape which account might fit you

Since there’s no single “best” plan for every self-employed person, it may help to think through these core questions:

1. How much do you realistically want to save each year?

• If you’re saving a relatively modest amount, an IRA may cover your needs.
• If you’re aiming to save significantly more, options like a solo 401(k), SEP, or even defined benefit plan may matter more.

2. Do you have employees now—or will you soon?

• No employees: you have maximum flexibility (solo 401(k) and SEP are on the table).
• A few employees: SIMPLE IRA or a full 401(k)-type plan may be more realistic.
• Planning to hire soon: what works this year (like a solo 401(k)) may need to change later.

3. Is your income steady or highly variable?

• Highly variable income:
  • Flexible options like SEP IRAs and solo 401(k)s let you dial contributions up and down.
• Steadier income:
  • You might be more comfortable with plans that involve required employer contributions (like SIMPLE IRA) or even defined benefit plans.

4. How much complexity are you willing to manage?

Think of it on a spectrum:

• Simplest: IRA → SEP IRA
• Moderate: SIMPLE IRA → Solo 401(k)
• Most complex: Traditional 401(k) with employees → Defined benefit plans

If you want to keep paperwork and record-keeping to a minimum, that tilts the decision.

5. Are you more focused on tax savings now or flexibility later?

If you:

• Want to cut taxes this year: traditional SEP, solo 401(k) employer contributions, or traditional IRA (if deductible) are geared toward that.
• Want tax-free income in retirement: Roth IRA or solo 401(k) with Roth deferrals might be more appealing.

Many people mix both, using some pre-tax and some Roth over their working years.

How multiple accounts can work together

You’re not locked into a single account type forever. Common combinations include:

• Solo 401(k) + Roth IRA

  • Use the solo 401(k) for big contributions and flexibility
  • Use the Roth IRA to build tax-free income later

• SEP IRA + Traditional or Roth IRA

  • SEP handles larger, business-level contributions
  • IRA gives flexibility and possibly Roth access if income allows

• Defined Benefit Plan + Solo 401(k)

  • Seen more with high earners wanting maximum deductions and savings
  • Comes with high complexity and professional oversight

The exact limits and interactions between accounts depend on:

• Whether you have other jobs with their own retirement plans
• How your business is structured (sole proprietor vs S-corp, etc.)
• Current tax law, which can change over time

Practical questions to ask yourself before choosing

To evaluate what fits you, it may help to sit with questions like:

1. How much can I comfortably set aside for retirement this year—and in a typical year?
2. Do I expect to hire employees or grow a team? If so, when?
3. Am I more focused on cutting today’s taxes, or on having more tax flexibility in retirement?
4. How much administrative work (forms, filings, plan documents) am I willing to take on—or pay someone else to handle?
5. Do I have income from another job with its own 401(k) or retirement plan? (That affects what you can contribute where.)
6. Is my self-employment income steady enough to support required contributions (like in a SIMPLE IRA or defined benefit plan)?

Your answers won’t spit out a single “correct” account type, but they’ll make it clearer where each option lines up—or doesn’t—with your reality.

Where planning basics meet your specific situation

All of these accounts—the IRA, SEP IRA, solo 401(k), SIMPLE IRA, and defined benefit plan—are just containers for your long-term savings with different:

• Tax treatments
• Contribution limits
• Rules about employees
• Levels of complexity

The “best” retirement account option for a self-employed person depends on your income level, whether you have employees, your appetite for complexity, and your tax priorities.

Once you understand the landscape, the next step is narrowing down options based on:

• What you can realistically save
• How your business might grow
• How much admin work you’re willing to accept
• And how important current tax deductions vs. future tax-free income are to you

That’s the line between planning basics (what we’ve covered here) and personal advice tailored to your situation. Knowing the basics puts you in a much stronger position to ask the right questions and choose an account type—or mix of them—that matches your goals and how you actually work.
