What is a Roth Solo 401(k)?
A Roth Solo 401(k) (also known as the Roth Individual 401(k)) is a retirement plan designed for self-employed individuals or small business owners with no full-time employees, except a spouse.
Unlike traditional Solo 401(k)s, contributions to the Roth portion are made with after-tax dollars. This means you won’t get a tax deduction up front, but both your contributions and any earnings grow tax-free, and qualified withdrawals in retirement are also tax-free.
The self-directed Roth Solo 401(k) is available to anyone with a Solo 401(k). It’s a benefit to higher-paid employees and self-employed individuals who may have been excluded from having a Roth IRA because of income limitations.
The Roth Individual 401(k) possesses the same benefits of the Individual 401(k) (higher contribution limits than other accounts), as the tax benefits of the Roth IRA. The contribution limits are the same as the Individual 401(k), but you can designate your contributions through salary deferral as Roth contributions.

Benefits of a Roth Solo 401(k)
High contribution limits: The Roth Solo 401(k) offers significantly higher contribution limits compared to other retirement accounts, allowing you to contribute more toward your future. This flexibility lets you adjust contributions based on your income and business performance, helping you maximize your retirement savings potential.
No required minimum distributions: Unlike traditional retirement accounts, Roth Solo 401(k) accounts are not subject to RMDs during your lifetime, allowing your investments to continue growing tax-free for as long as you want.
Loan options: With a Roth Solo 401(k), you can borrow up to 50% of your account balance or $50,000, whichever is less. Loans must be repaid within five years, offering financial flexibility without taxes or penalties if repaid on time.
Spousal participation: If your spouse works in your business, they can also open and contribute to a Roth Solo 401(k), effectively doubling the contribution potential for your household.

Roth Solo 401(k) Eligibility Requirements
Like the Individual 401(k), the Roth Solo 401(k) is for incorporated and unincorporated businesses, sole proprietorships, partnerships, and corporations. The only requirement for contributions to this plan is that you receive a salary or wage.
The business entity must have no additional employees other than the spouse of the proprietor—or, in the case of a partnership, the only employees must be self-employed partners and their spouses. An Individual 401(k) plan must be the only arrangement maintained by the business that is not included as part of a controlled group under federal tax law.
The deadline for establishing an Individual 401(k) plan is the last day of your business’s tax year (December 31, for a calendar tax year). However, if your business is incorporated, you may want to establish an Individual 401(k) plan early in the tax year to make employee salary deferrals based on the Form W-2 income throughout the year.
This is necessary because you may not defer on compensation that is paid to you from your corporation before you establish the Individual 401(k) plan.
Roth Solo 401(k) Account Rules
Required holding period: To qualify for tax-free distributions of both contributions and earnings, the Roth Solo 401(k) must be held for at least five years. This rule applies even if you are already over 59½.
Qualified distributions: Distributions from the Roth Solo 401(k) are tax-free if you are 59½ or older and have met the five-year holding period. Withdrawals before 59½ or without meeting the holding period may result in taxes and penalties on the earnings portion.
Employer contributions: Employer contributions must be made on a pre-tax basis and cannot be designated as Roth contributions. These contributions will be taxed as ordinary income when withdrawn.
Rollover restrictions: You can roll over a Roth Solo 401(k) into a Roth IRA upon retirement or leaving the business. However, certain rules apply to ensure tax-free treatment, such as the five-year holding period and distribution timing.
Roth Solo 401(k) and Taxes
Contributions to a Roth Solo 401(k) are made with after-tax dollars, meaning they don’t reduce your taxable income in the year they’re made. However, both contributions and any earnings grow tax-free. When you reach retirement age, qualified withdrawals—including contributions and earnings—are completely tax-free.
Employer contributions are made pre-tax and are taxed upon withdrawal. Non-qualified withdrawals from employer contributions or earnings before age 59½ may incur taxes and a 10% early withdrawal penalty.
In addition to after-tax Roth contributions, a Roth Solo 401(k) allows for pre-tax profit-sharing contributions. As an employer, you can contribute up to 25% of your compensation toward the pre-tax portion of the plan.
These contributions may provide a valuable tax deduction in the year they are made, reducing your taxable income. While these profit-sharing contributions grow tax-deferred, they will be subject to taxes when withdrawn during retirement.
