The Retirement Gap for Detroit's Independent Workers
W2 employees often receive an employer match on their 401k contributions — free money deposited automatically every pay period. They may also have automatic enrollment that begins building retirement savings from their first day of work. Self-employed workers receive none of this.
Detroit freelancers fund retirement entirely on their own, from income that may vary significantly month to month, without the behavioral nudges of auto-enrollment. The result is a significant retirement savings gap for Detroit's independent workforce. FHR's Protection Score data consistently shows retirement as one of the lowest-scoring gaps among Detroit freelancers.
The opportunity: While the lack of employer support is a real disadvantage, self-employed workers have access to retirement accounts with significantly higher contribution limits than standard employee 401k plans. A Detroit freelancer maxing a Solo 401k in 2026 can contribute up to $70,000 — far more than the $23,500 employee-only limit in a standard workplace plan.[1]
Solo 401k: The Most Powerful Option for Detroit Freelancers
The Solo 401k (also called an Individual 401k or Self-Employed 401k) is available to self-employed individuals with no full-time employees other than a spouse. It allows contributions in two capacities: as an employee and as the employer.
2026 Solo 401k Contribution Limits
As an employee, you can contribute up to $23,500 of net self-employment income, or 100% of net SE income if it is less than $23,500. Adults 50 and older can make an additional $7,500 catch-up contribution, and adults 60-63 can contribute up to $11,250 as a catch-up under SECURE 2.0 rules.[1]
As the employer, you can contribute up to 25% of net self-employment income (after the SE tax deduction). The combined employee and employer contributions cannot exceed $70,000 in 2026 ($77,500 for those 50 or older).[1]
Solo 401k Roth Option
Many Solo 401k providers offer a Roth option for employee contributions. Roth contributions are made with after-tax dollars and grow tax-free, with qualified withdrawals in retirement also tax-free. For Detroit freelancers who expect to be in a higher tax bracket in retirement, the Roth Solo 401k can be advantageous. The employer portion of Solo 401k contributions must be traditional (pre-tax).
Solo 401k Loan Provision
Unlike IRAs, Solo 401k plans can include a loan provision allowing you to borrow up to 50% of your vested balance or $50,000, whichever is less. This provides a liquidity option for Detroit freelancers who may face income gaps, though FHR does not recommend routine reliance on retirement account loans.
Solo 401k Administrative Requirements
Once your Solo 401k balance exceeds $250,000, you are required to file Form 5500-EZ with the IRS annually. Below that threshold, administration is minimal. You must establish the plan by December 31 of the year for which you want to make contributions, though contributions themselves can be made until your tax filing deadline including extensions.[2]

The Simplified Employee Pension IRA (SEP IRA) is the simplest retirement account option for self-employed workers. It requires no special plan documents and can be opened and funded up to your tax filing deadline including extensions.[2]
2026 SEP IRA Contribution Limits
SEP IRA contributions are limited to 25% of net self-employment income (after the SE tax deduction) up to a maximum of $70,000 in 2026.[1] Unlike the Solo 401k, there is no employee contribution component — only the employer percentage applies.
This means at lower income levels, the SEP IRA allows smaller contributions than the Solo 401k. At $40,000 in net SE income, the SEP IRA maximum is $10,000, while the Solo 401k allows up to $23,500 (the full employee contribution) plus the employer percentage.
SEP IRA Disadvantages
The SEP IRA has two significant limitations. First, it does not offer a Roth option — all SEP IRA contributions are traditional (pre-tax), meaning withdrawals in retirement are taxed as ordinary income. Second, if you hire full-time employees, you must make proportional SEP IRA contributions for eligible employees, which can be costly. Solo 401k plans do not have this requirement.
Comparing Solo 401k and SEP IRA for Detroit Freelancers

FHR's General Guidance
For most Detroit freelancers, the Solo 401k is the superior choice because it allows significantly higher contributions at lower income levels, offers a Roth option, and has a loan provision. The SEP IRA is appropriate for freelancers who want maximum simplicity, are approaching retirement and primarily need the employer contribution percentage, or are considering hiring employees in the near future.

When to Open Your Retirement Account
The most common mistake Detroit freelancers make with retirement accounts is waiting. Every year of delay has compounding consequences that are difficult to recover from later. FHR's guide When to Start Your Retirement Account walks through the math of delayed contributions at common Detroit freelancer income levels.
The general principle: open your retirement account in your first year of self-employment even if your initial contributions are small. The habit, the account structure, and the compounding foundation all matter more than the initial contribution size.
Tax Benefits of Retirement Contributions for Detroit Freelancers
Retirement contributions to Solo 401k and SEP IRA plans reduce your adjusted gross income dollar for dollar, lowering your federal income tax, Michigan state income tax, and potentially your Detroit city income tax. Importantly, retirement contributions also reduce your MAGI for ACA Marketplace subsidy purposes, which can increase health insurance subsidies for Detroit freelancers in the relevant income range.

Frequently Asked Questions
Can I have both a Solo 401k and a SEP IRA?
Generally no — you cannot contribute to both a Solo 401k and a SEP IRA for the same business in the same year. You choose one for each tax year. If you have income from multiple businesses or a W2 job alongside freelance work, the rules are more complex and FHR recommends consulting a CPA.
Where do Detroit freelancers open a Solo 401k?
Major brokerages including Fidelity, Schwab, and Vanguard offer Solo 401k plans with no annual fees. Fidelity's Solo 401k includes a Roth option. Setup typically takes 15-30 minutes online and the account must be established by December 31 of the contribution year.
What happens to my Solo 401k if I hire employees?
If you hire a full-time employee who is not your spouse, you can no longer contribute to a Solo 401k for that year. You would need to convert to a different plan structure. This is a consideration for Detroit freelancers who may be growing toward hiring. The SEP IRA allows employees but requires proportional contributions for eligible staff.
Are retirement contributions deductible on my Michigan state return?
Yes. Solo 401k and SEP IRA contributions that reduce your federal AGI also reduce your Michigan taxable income, providing state tax savings at Michigan's 4.25% rate in addition to the federal deduction.
