Self-employed retirement: your four main options

Self-employed people have four main retirement accounts to choose from: the traditional IRA, the Roth IRA, the SEP IRA, and the solo 401(k). IRAs are the simplest to open and let you contribute a smaller amount each year. The SEP IRA and solo 401(k) are built for business owners and let you set aside much more once you are earning real profit. The best choice depends on your income, whether you have employees, and how much paperwork you can stomach.

Why is retirement harder when you work for yourself?

A job hands you a 401(k) with matching, automatic payroll deductions, and a default fund already picked. You had to opt out to not save. Working for yourself removes every one of those nudges. Nobody enrolls you, nobody matches you, and nobody moves the money before you can spend it.

So retirement becomes one more thing that only happens if you make it happen. The good news is that the self-employed options are genuinely strong, often stronger than what an employer offers, because you can play both the employee and the employer. The catch is that you have to choose the account, open it, and automate the contributions yourself.

The mistake I see most is waiting for a perfect year to start. There is no perfect year. There is only the account you opened and the small contribution you made automatic.

What are the four main self-employed retirement accounts?

Each account trades off contribution room, tax treatment, and effort. Here is the plain-language version, with no dollar limits, because those change and your CPA will give you the current ones.

Traditional and Roth IRA

These are the on-ramp. Anyone with earned income can usually open one at a brokerage in an afternoon. They share the same annual contribution ceiling, which is modest, and the difference between them is timing. A traditional IRA gives you a tax break now and taxes the withdrawals later. A Roth flips it, no break now, tax-free money later. Which one wins depends on whether you think your tax rate will be higher today or in retirement, and that is a real conversation to have with a financial advisor.

SEP IRA

Once your profit climbs, an IRA's ceiling starts to feel small. A SEP IRA lets you contribute far more, as a percentage of your income, and it is still simple to open and run. It is a favorite for solo owners because the paperwork is light. The one thing to know is that if you have employees, a SEP generally requires you to contribute for them too, on the same terms, which changes the math.

Solo 401(k)

For an owner with no employees who wants to save the most possible, the solo 401(k) is usually the winner. It lets you contribute in two roles at once, as the employee and as the employer, which stacks into the highest total of the four. Many versions also offer a Roth side and the option to borrow from the balance. The tradeoff is a bit more setup and, past a certain balance, an annual filing. For high earners socking away serious money, that effort pays off.

How do I pick one without overthinking it?

Do not overthink the first move. The account you will fund beats the theoretically optimal account you keep researching. A simple way to narrow it down.

Whatever you land on, the move that matters is automation. Set a recurring transfer into the account, the same way you run your owner paycheck, so the money leaves before you can spend it. The cleanest setup carves the retirement contribution out of every deposit as one more slice of your deposit-day split. Retirement saving fails on willpower and succeeds on autopilot.

What does starting look like for a real owner?

A consultant I'll call Dana spent three years telling herself she would start retirement savings once revenue felt stable. It never felt stable, because variable income never does. Her profit had grown to around $140,000 a year, and she had nothing set aside.

She opened a SEP IRA in one afternoon and set an automatic monthly transfer of $1,500, a number her worst month could still cover. In a strong quarter she added a lump sum on top. She did not wait for certainty. She picked an account her income could handle and made it boring.

The exact dollars matter less than the shift. Dana went from zero to a funded retirement account running on autopilot, and she can raise the amount as profit grows. If your profit is not yet high enough to fund the account you want, that is the real bottleneck. The Scale Plan turns a few questions about your business into a personalized 30-day growth plan in about 15 minutes, so there is more profit to save from.

Do this next

Pick the account that matches your answers to the four questions above and open it this week, even if your first automatic contribution is small. Then set one recurring transfer so it funds itself. A CPA or financial advisor should confirm the account and the current contribution limits for your specific income and structure before you max anything out. If thin profit is the real blocker, the Scale Plan maps your next 30 days of growth.
