Solo 401k: The Retirement Move Founders Keep Skipping
Many founders answer the retirement question the same way, telling a widely shared 24/7 Wall St analysis that they will simply sell the company one day. A solo 401k offers a steadier path, and in 2026 it lets a self-employed owner shelter up to $80,000.
That gap between a hopeful exit and a funded account is the real story. Selling a business is one uncertain event, while a retirement plan compounds quietly for decades. Founders already track small business profitability with care, so applying the same discipline to personal savings is a natural next step.
Why Betting on a Sale Is Risky
A business sale looks like a retirement plan, yet it behaves like a gamble. Buyers can walk away, valuations can compress, and industries can shift faster than expected. A health scare can also force an early exit at a weak price.
When all of that lands on one transaction, your entire retirement rides on timing you do not control. In contrast, a tax-advantaged account keeps growing no matter what the market does to your company’s value.
Consider the odds too. Most small businesses never sell for a life-changing sum, and many never sell at all. Building a separate account means your future does not depend on finding the perfect buyer at the perfect moment.
How the Solo 401k Works in 2026
The solo 401k is built for owners with no full-time employees besides a spouse. You contribute as both the employee and the employer, which is why the limits run high. For 2026, total contributions reach up to $72,000 for owners under 50 and up to $80,000 for those 50 and older with catch-ups.
| Owner age | Maximum total contribution |
|---|---|
| Under 50 | Up to $72,000 |
| 50 and older | Up to $80,000 |
Because you wear both hats, you can move large sums in strong years and less in lean ones. You also get flexibility on taxes, since many providers let you choose traditional contributions that lower your bill today or Roth contributions that grow tax-free for later.
The IRS explains the current rules and deadlines on its one-participant 401k page, which is worth a careful read before you open one.
The Savings Signal Founders Should Not Ignore
Personal savings are getting thinner across the country. The household savings rate slipped from about 6.2 percent in early 2024 to 3.9 percent by early 2026, even as per-person disposable income rose to $68,391. In other words, people earn more yet keep less.
Meanwhile, the amount Americans think they need for retirement climbed to roughly $1.46 million in 2026. For founders who reinvest every dollar into the company, that target can feel out of reach without a deliberate plan.
That mix of thinner savings and higher targets is exactly why a structured account matters now. A solo 401k answers both problems at once, because it forces a habit of paying yourself first and shelters growth from taxes along the way.
Fit It Into Your Tax Strategy
Retirement saving works best beside your other tax moves. Founders already use tools like the capital gains tax exclusion to keep more of an eventual exit. A solo 401k adds a second lever that lowers taxable income today.
Health coverage belongs in the same plan. Owners weighing ICHRA health benefits can pair those savings with retirement contributions to stretch limited cash further. Together, these choices turn scattered decisions into one coherent framework.
How to Think About the First Step
Start small if you must, but start this year. Even a modest contribution builds the habit and opens the account before the December deadline. You can raise the amount as cash flow improves.
Then automate it. Set a recurring transfer so saving no longer competes with daily fires. Above all, keep it boring and consistent, because steady contributions in a low-cost account almost always beat a dramatic bet on one exit.
