Roth Solo 401(k) for Self-Employed Entrepreneurs

If you are an entrepreneur, independent contractor, Realtor, consultant, or small-business owner, you probably spend a tremendous amount of time thinking about how to grow your business. But there is another question that deserves just as much attention: What are you doing to build your retirement outside of your business?

For many entrepreneurs, the answer is real estate. I understand that thinking. As a Realtor and someone passionate about building generational wealth, I absolutely believe real estate can be an incredible wealth-building tool. But I also believe that building wealth should not depend on one asset class. Real estate, business ownership, life insurance, retirement accounts, cash reserves, and other investments can each play different roles in a well-designed financial strategy.

That is why self-employed entrepreneurs should understand a potentially powerful retirement tool: the Roth Solo 401(k). A Solo 401(k), also referred to by the IRS as a one-participant 401(k) plan, can provide eligible business owners with an opportunity to save significant amounts for retirement while potentially building a source of tax-free qualified retirement income.

What Is a Roth Solo 401(k)?

A Solo 401(k) is a 401(k) retirement plan designed for a business owner with no common-law employees other than potentially the owner’s spouse. Unlike a Roth IRA, which is an individual retirement account, a Solo 401(k) is an employer-sponsored retirement plan connected to the owner’s business.

When the plan permits designated Roth contributions, an eligible business owner may make employee elective deferrals to the Roth portion of the Solo 401(k). Those Roth contributions are made with after-tax dollars. In other words, you generally don’t receive a current income-tax deduction for the Roth contribution. In exchange, qualified distributions from the Roth account, including associated investment earnings, can generally be received free from federal income tax.

For 2026, the employee elective-deferral limit for a 401(k) is $24,500. Participants age 50 or older generally have an additional $8,000 catch-up opportunity, while a special $11,250 catch-up limit applies to participants ages 60 through 63. The overall defined-contribution limit is $72,000 for 2026 before applicable catch-up contributions.

The actual amount a business owner can contribute depends on factors including compensation, business structure, other retirement plans, plan provisions, and applicable tax rules. That’s why establishing and funding a Solo 401(k) should be coordinated with qualified tax and financial professionals.

Who Is Eligible for a Solo 401(k)?

This is where the strategy becomes particularly interesting for entrepreneurs. A one-participant 401(k) is generally intended for a business owner with no common-law employees other than a spouse. That can make it relevant to independent contractors, consultants, freelancers, and many other self-employed professionals.

That potentially includes Realtors.

Many real estate professionals operate as independent contractors and think about their real estate businesses primarily as sources of current income. A strong year means more commissions, more transactions, and perhaps another investment property. But successful entrepreneurship should also create opportunities to convert some of today’s income into assets designed to support tomorrow’s lifestyle.

A Solo 401(k) is particularly interesting because the owner can participate in two capacities: employee and employer. That structure can create retirement-saving opportunities that are considerably different from simply making a contribution to an IRA. The calculations can also become more complicated for self-employed individuals, making professional tax guidance especially important.

Why the Roth Component Can Be So Powerful

The word Roth describes how certain contributions and eventual distributions are treated for tax purposes. With traditional pre-tax retirement contributions, you may receive a tax benefit today and generally pay income taxes when taxable money is withdrawn later. With designated Roth contributions, you pay taxes on that income now in exchange for the potential to receive qualified distributions tax-free later.

Think about what that could mean over several decades.

Suppose an entrepreneur consistently contributes to the Roth portion of a Solo 401(k) and invests that money for long-term growth. The account could potentially experience years, or decades, of compounded investment growth. When applicable requirements for qualified distributions are eventually satisfied, those distributions, including associated earnings, can generally be excluded from federal gross income.

Nobody knows what federal tax rates will look like 20 or 30 years from now. Having retirement assets with different tax characteristics may provide additional flexibility when planning future retirement income.

Realtors Should Diversify Beyond Real Estate

Real estate professionals can understandably develop a preference for real estate because it is what we know. We see appreciation, rental income, leverage, equity, and investment opportunities every day. Real estate can absolutely be part of a long-term wealth strategy, but that doesn’t mean every available investment dollar needs to go into another property.

Properties require maintenance. Tenants can leave. Markets change. Property taxes and insurance costs can increase. Properties can sit vacant, and accessing equity may require selling or borrowing against the asset. A diversified retirement portfolio can provide something different.

This isn’t an argument for choosing a Roth Solo 401(k) instead of real estate. It’s about considering whether your financial strategy should include both.

Imagine reaching retirement with investment properties producing income, a business or other assets creating value, life insurance supporting your legacy strategy, cash reserves providing liquidity, and retirement accounts containing investments that have compounded for decades. Different assets are doing different jobs instead of requiring one asset class to accomplish everything.

That is what diversification means to me.

Turn Today’s Business Success Into Tomorrow’s Freedom

Entrepreneurs frequently reinvest everything into their businesses. There is always another marketing campaign, piece of equipment, investment opportunity, property, employee, or expansion plan competing for capital. Building the business matters, but entrepreneurs shouldn’t become so focused on funding the business that they forget to fund themselves.

A Roth Solo 401(k) can provide a structured way for an eligible entrepreneur to take some of the income the business produces today and intentionally direct it toward the future.

The objective isn’t simply to become wealthy on paper. The objective is to create options. Retirement planning can help create the financial freedom to work because you want to work rather than because you have to work.

If you’re self-employed, particularly if you’re a Realtor, independent contractor, or small-business owner, consider asking your CPA, tax professional, or financial professional whether a Solo 401(k) with a Roth contribution option belongs in your retirement strategy. You worked hard to create your business. Now consider putting that business to work building your retirement and your legacy.
