SEP IRA for Self-Employed

If you're self-employed — freelancer, consultant, small business owner, gig worker, or independent contractor — a SEP IRA (Simplified Employee Pension) is one of the simplest and most generous retirement accounts available. It takes minutes to set up, has almost no paperwork, and lets you contribute up to $70,000 per year (for 2025). For high-earning self-employed individuals, it's one of the fastest ways to slash your tax bill while building retirement wealth.

How It Works

A SEP IRA is an employer-contributed retirement plan where you are both the employer and the employee. You set up the account at any brokerage (Fidelity, Schwab, Vanguard are popular choices), and contributions are made by the "employer" (you, as your own business) on behalf of the "employee" (also you).

Contributions are 100% tax-deductible as a business expense. They reduce your self-employment income, which reduces both your income tax and your self-employment tax. The money grows tax-deferred inside the account — no taxes on gains, dividends, or interest until you withdraw in retirement.

Contribution limit for 2025: The lesser of 25% of net self-employment income or $70,000. "Net self-employment income" means your profit minus the deductible half of self-employment tax — so the effective maximum percentage is closer to 20% of gross self-employment profit.

Who Should Use a SEP IRA

The SEP IRA is ideal for:

• Solo self-employed individuals with no employees (or only a spouse employee)
• High earners who want to shelter a large amount of income — up to $70,000 per year
• People who want simplicity — no annual tax filings (like a Form 5500), no compliance testing, no administrative burden
• Those with variable income — contributions are completely flexible. You can contribute the maximum one year and nothing the next

SEP IRA vs Solo 401(k)

This is the most common question, and the answer depends on your situation.

SEP IRA advantages: Simpler to set up and maintain. No annual reporting requirements. Good choice if you want minimal paperwork.

Solo 401(k) advantages: Allows both employee contributions ($23,500 for 2025) and employer contributions (25% of income), potentially allowing higher total contributions at lower income levels. Also offers a Roth option, and allows loans from the account.

The crossover point: If your net self-employment income is below about $200,000, a Solo 401(k) often lets you contribute more total dollars because of the employee contribution component. Above $200,000, the two accounts converge and the SEP's simplicity wins.

The Math

If you're a freelance consultant earning $150,000 in net self-employment income, your maximum SEP contribution is about $27,900 (roughly 20% of net after the self-employment tax deduction). At the 24% tax bracket, that saves you roughly $6,700 in income taxes plus reduces your self-employment tax.

At $300,000 in net income, your maximum contribution is about $55,800 — saving over $13,000 in taxes.

Invested for 20 years at 9% annual returns, a $28,000 annual contribution becomes approximately $1.6 million. A $56,000 annual contribution becomes approximately $3.2 million. That's the power of combining high tax-deductible contributions with decades of tax-deferred growth.

Important Rules

Deadline: SEP IRA contributions can be made up to your tax filing deadline, including extensions. If you file for an extension, you have until October 15 to make contributions for the prior tax year. This is extremely valuable — you can see your final income for the year and then optimize your contribution.

Employee considerations: If you have employees (other than a spouse), you must contribute the same percentage for them as you do for yourself. This can make SEP IRAs expensive for businesses with multiple employees — in that case, a SIMPLE IRA or 401(k) may be more appropriate.

No Roth option: SEP IRAs are traditional (pre-tax) only. There's no Roth SEP IRA. If you want Roth contributions, you need a Solo 401(k) or a separate Roth IRA.

Pro-rata rule: Having a SEP IRA affects your ability to do a Backdoor Roth IRA. The SEP balance is included in the pro-rata calculation, which can create an unexpected tax bill on Roth conversions. If you plan to use the Backdoor Roth strategy, a Solo 401(k) is usually better because the balance doesn't trigger the pro-rata rule.
