Introduction
When you work for yourself, nobody enrolls you in a 401(k) or matches your contributions. You build the retirement structure from scratch, and you may need to plan for employees too.
Many owners put it off. A Pew analysis found only about 13% of self-employed workers ages 50 to 64 in single-person firms participated in a retirement plan.
Each plan differs in eligibility, contribution mechanics, tax treatment, paperwork, and employee obligations. This guide walks through the main options and the criteria for choosing among them.
Key Takeaways
- Options include Solo 401(k)s, SEP IRAs, SIMPLE IRAs, standard or safe-harbor 401(k)s, IRAs, HSAs, and defined benefit plans.
- Employees, income pattern, tax goals, and growth plans drive the right choice.
- Confirm current IRS limits and deadlines before funding anything.
- A plan is only the account; investments and withdrawals still need a strategy.
What Are Retirement Plans for Self-Employed People?
A self-employed retirement plan is a tax-advantaged account or plan that lets a business owner save from business income through personal contributions, employer contributions, or both. Sole proprietors, independent contractors, partnerships, and S corporations can all use them, though compensation calculations vary by entity.
Without automatic enrollment, you must set a savings rate, pick a plan, manage investments, and fit it all around cash flow and taxes.
Two cautions:
- "Self-employed" does not automatically mean Solo 401(k) eligible. Common-law employees, a working spouse, and hiring plans change your options.
- S-corporation shareholder distributions are not earned income for plan purposes. Only wages count.
All figures below are for tax year 2026 unless noted. Confirm them against current IRS guidance.
Retirement Plan Options for Self-Employed People
Solo 401(k)
A Solo 401(k), also called a one-participant 401(k), generally fits an owner with no common-law employees other than a spouse. You contribute in two roles: as employee and as employer.
- Employee deferrals: up to $24,500, or 100% of compensation if less
- Employer contributions: generally up to 25% of compensation, using a special earned-income calculation for the self-employed
- Total annual additions: capped at $72,000, before catch-ups
- Catch-up: $8,000 at 50+, or $11,250 at ages 60 to 63
Roth deferrals, loans, and self-directed investing depend on your plan document and provider. The IRS contribution limits page lists the current figures. Form 5500-EZ is generally required once plan assets reach $250,000 at year-end.
SEP IRA
A SEP IRA is employer-funded and simple to run. Only the employer contributes, and employees cannot defer salary. You can skip a year, but when you contribute, every eligible employee gets the same percentage of pay that you give yourself.
- Limit: the lesser of 25% of compensation or $72,000
- Standard eligibility: age 21, work in 3 of the last 5 years, and at least $800 of pay
- Deadline: your business tax return due date, including extensions
SEPs suit variable profits, since contributions flex with income. The trade-off is cost: as you hire, matching percentages for staff add up fast.
SIMPLE IRA
A SIMPLE IRA suits employers with 100 or fewer employees and no other retirement plan. Employees defer salary, and the employer must contribute every year.
- Employee deferral: $17,000 (up to $18,100 for certain arrangements), plus catch-up of $4,000 at 50+
- Employer choice: match up to 3% of pay, or a 2% contribution for all eligible employees
- Early withdrawals in the first two years face a 25% additional tax
Contribution ceilings sit below 401(k) levels, but administration is lighter. SEP and SIMPLE plans generally cost less to administer than a 401(k).
Standard or safe-harbor 401(k)
If you have employees or expect to hire, a traditional or safe-harbor 401(k) may beat a Solo 401(k). Standard plans face ADP and ACP nondiscrimination testing. Safe-harbor designs avoid most testing in exchange for required employer contributions: a 3% nonelective contribution or a basic match.
Expect annual Form 5500 reporting, fiduciary duties, fee oversight, and often a third-party administrator. The Department of Labor treats plan fee review as an ongoing fiduciary responsibility.
Traditional or Roth IRA and HSA supplements
IRAs can sit alongside a business plan. The combined 2026 limit is $7,500, or $8,600 at 50+. Traditional contributions may be deductible; qualified Roth withdrawals are tax-free. Roth eligibility phases out at $153,000 to $168,000 of income for single filers.
An HSA adds separate savings if you are in an eligible high-deductible health plan. The 2027 limit is $4,500 self-only or $9,000 family, with a $1,000 catch-up at 55+.
Defined benefit or cash balance plan
These plans target a promised retirement benefit and can allow far larger contributions for older, high-earning owners. The 2026 benefit limit is generally the lesser of $290,000 or 100% of your highest three-year average pay.
The costs are real: actuarial work, higher fees, mandatory annual funding, and employee coverage rules. Treat this as a specialized option for stable cash flow, not a default.

How to Choose the Right Retirement Plan
Pick by fit, not popularity, headline limits, or one year's deduction.
Business structure, employees, and growth plans
Ask whether you have no employees, a working spouse, current staff, or hiring plans. Hiring eligible employees ends Solo 401(k) status. With staff, a SEP requires the same contribution percentage for everyone, and a SIMPLE requires an annual employer contribution.
Income pattern and savings objective
- Stable high income: Solo 401(k) or, with staff, a safe-harbor 401(k); a defined benefit plan if you want to save much more
- Variable or seasonal income: SEP, since contributions are optional each year
- Modest profits: SIMPLE or Solo 401(k) deferrals can work well
- Catch-up goals: 401(k) and SIMPLE plans offer catch-ups
Contribution math depends on how compensation is defined for your entity, so run your own numbers with a professional.
Tax strategy and desired account treatment
Pre-tax contributions give a deduction now, while Roth contributions offer tax-free qualified withdrawals later. Mixing both can diversify your tax picture, though results still depend on income, filing status, other plans, and changing law.
Administration, fees, and employer responsibilities
Compare the full cost of ownership, not just contribution limits:
- Setup and annual administration fees
- Recordkeeping, testing, and employee notices
- Required employer contributions
- Investment costs
A SEP mainly requires the employer to contribute by the tax deadline. A 401(k) carries far more ongoing obligations. Weigh total cost and duties together.

Investment control, distributions, and professional support
Review the investment menu, self-directed options, withdrawal rules, rollovers, and creditor protection. Self-directed does not mean risk-free. You still need a coherent strategy and regular monitoring.
What to Check Before Finalising a Plan
What to Check Before Finalizing a Plan
- Test the math. Don't choose a plan only because it advertises the highest limit. Confirm it works for your compensation, cash flow, entity type, and workforce.
- Verify the rules. Check IRS guidance on adoption and funding deadlines, eligibility, required notices, filing duties, and catch-up provisions. Sole proprietors with no employees can adopt a 401(k) after year-end by the return due date, without extensions.
- Compare providers. Look at fees, fiduciary responsibilities, and service levels. North Carolina owners seeking personalized fiduciary guidance can talk with Lewis & Associates Capital Advisors, LLC, an independent advisory firm in Holly Springs and Raleigh that offers tailored wealth and retirement planning, including SEP and SIMPLE plans. Take tax and legal questions to your own qualified professionals.
- Look beyond the plan. Emergency reserves, succession, insurance, estimated taxes, Social Security coordination, and a retirement income plan all matter too.

Conclusion
Self-employed workers have many choices, and each fits a different mix of business size, employee needs, income pattern, tax goal, and tolerance for paperwork. Revisit the decision as your business grows, you add staff, your income shifts, or retirement nears.
Verify current rules and coordinate financial, tax, and legal advice before you commit.
Frequently Asked Questions
How do you save for retirement if you're self-employed?
Use a Solo 401(k), SEP IRA, SIMPLE IRA, 401(k), IRA, HSA, or a defined benefit plan. The right one depends on your employees, income, tax goals, and appetite for administration.
Can I open my own 401(k) if I'm self-employed?
Yes, if you have no common-law employees other than a spouse. Hiring eligible employees generally ends one-participant status, so verify plan and entity rules first.
What is the best retirement plan for a self-employed person with employees?
SIMPLE IRAs are cheap and easy but require annual employer contributions. SEPs require equal percentages for everyone. Safe-harbor 401(k)s cost more to run but allow higher limits. Weigh fees and your growth plans when you choose.
What are the key differences between a Solo 401(k) and a SIMPLE IRA?
A Solo 401(k) is for owners without employees and allows higher contributions. A SIMPLE IRA covers employers with up to 100 employees, requires employer contributions, and has lower limits and lighter administration.
What is the most overlooked retirement tax break?
It varies by person. Ask a tax professional about employer contribution deductions, catch-up provisions, and startup credits of up to $5,000 per year for eligible small employers.
What is the biggest mistake most people make regarding retirement?
Not starting, or contributing inconsistently. Others pick a plan without considering future hires and fees, or ignore retirement income and tax planning. Review your plan periodically.
