Many people think you need a traditional job with a corporate HR department to open a Roth 401(k). The truth is, if you’re self-employed, you can open a Roth Solo 401(k) and access powerful retirement savings benefits—without having an employer.
Whether you’re a freelancer, independent contractor, small business owner, or side hustler, this guide will walk you through how it works.
Watch: Learn how the self-employed can also open a Roth 401k
1. Understanding the Roth Solo 401(k)
A Roth Solo 401(k) is designed for self-employed individuals with no non-owner full-time employees. You can operate as:
-
A sole proprietor (filing Schedule C)
-
An LLC or S corporation
-
A partnership
You simply need earned income from self-employment. Your spouse can also participate if they work in your business.
2. Roth Solo 401(k) vs. Roth IRA
While both are after-tax accounts, they differ in key ways:
| Feature | Roth Solo 401(k) | Roth IRA |
|---|---|---|
| Annual Contribution Limit (2025) | Up to $23,500 (employee) + employer contributions, potentially reaching $70,000 | $7,000 |
| Employer Contributions | Allowed (and can be Roth) | Not applicable |
| Mega Backdoor Roth Option | Yes, via voluntary after-tax contributions and conversion | No |
| Loan Option | Yes — borrow up to $50,000 or 50% of account balance | Not allowed |
3. How Much You Can Contribute
For 2025:
-
Employee Roth contributions: Up to $23,500
-
Employer Roth contributions: Up to 20–25% of self-employment income (depending on entity type)
-
Mega Backdoor Roth: Voluntary after-tax contributions up to the $70,000 overall limit, then converted to Roth
Example:
If your S-corp pays you $100,000 in W-2 wages, you could contribute:
-
$23,500 (employee Roth)
-
$25,000 (employer Roth)
-
$21,500 (voluntary after-tax → converted to Roth)
Total Roth Contributions: $70,000
You also may choose to solely make voluntary after-tax solo 401k contributions up to the overall limit which is $70,000 for 2025 and then convert the contribution to the Roth Solo 401k or the Roth IRA as part of the mega backdoor Roth Solo 401k strategy.
4. Who Qualifies
You qualify if you:
-
Have self-employment income
-
Do not employ non-owner W-2 employees working 1,000+ hours/year
-
Want to maximize Roth savings beyond IRA limits
Even if you have a day job with a 401(k), you can still open a Solo 401(k) for your side business.
