Retirement Planning for Self-Employed and Freelancers

Without an HR department setting up a 401(k) or providing a company match, self-employed individuals and freelancers must build their own retirement infrastructure. The good news is that the IRS provides specialized accounts with massively higher contribution limits than standard employee plans.

The Solo 401(k): The Gold Standard

For solopreneurs with no employees (other than a spouse), the Solo 401(k) is unparalleled. You act as both the employee and the employer. In 2025, you can contribute $23,500 as the "employee," plus 20% of your net self-employment income as the "employer" profit-sharing contribution, up to a massive combined maximum of $69,000. It also allows for a Roth option.

The SEP IRA: Simplicity

The Simplified Employee Pension (SEP) IRA is easier to set up and administer than a Solo 401(k). You can contribute up to 25% of your net self-employment income (or 20% depending on tax structure), up to $69,000. The drawback is there is no "employee" deferral, meaning if your income is modest, you can contribute far less to a SEP than you could to a Solo 401(k).

Managing Irregular Income

Freelancers face feast-or-famine income cycles. The best strategy is to establish a larger-than-normal emergency fund (6 to 12 months instead of 3 to 6) to smooth out cash flow. Wait to make large retirement contributions until the fourth quarter when your tax liability and total income for the year are clear.

The Self-Employment Tax Reality

Self-employed individuals pay the full 15.3% FICA tax (both the employee and employer halves). While pre-tax retirement contributions (like to a SEP IRA) reduce your income tax liability, they do NOT reduce your self-employment FICA tax liability. Planning for this tax burden is critical to avoid cash flow crunches.

Key Takeaways

• Self-employed workers have access to accounts with massive contribution limits (up to $69,000).
• The Solo 401(k) allows for the highest contributions at lower income levels.
• The SEP IRA is simpler to administer but lacks the employee deferral feature.
• Maintain a larger emergency fund to manage irregular cash flows.
• Pre-tax contributions reduce income tax, but not FICA self-employment taxes.

Frequently Asked Questions

Can I have a Solo 401(k) if I have a W-2 day job?
Yes, if you have a side hustle with 1099 income. However, the $23,500 employee deferral limit is shared across ALL 401(k)s you have.

What if I hire an employee?
If you hire W-2 employees (who work more than 1,000 hours/year), you can no longer use a Solo 401(k). You must transition to a standard 401(k), SEP IRA, or SIMPLE IRA.

Can I do a backdoor Roth with a SEP IRA?
Having a SEP IRA balance interferes with the Backdoor Roth strategy due to the IRS pro-rata rule. A Solo 401(k) does not trigger the pro-rata rule.
