You built something real. Revenue is up. Your business runs without you micromanaging every decision. By every external measure, you've made it. But here's the question most entrepreneurs never stop to honestly answer: when the business stops, what do you actually have?
This is the core challenge of retirement planning for business owners, and it's one of the most common financial blind spots we see at Moment Private Wealth. High earners who have been generating serious income for years, sometimes decades, but have little to show for it outside the business itself. If you want to learn more
With greater income comes greater responsibility. Business owners who fail to structure their finances correctly don't just miss opportunities; they leave serious money on the table. Having the right financial team isn't optional. It's the difference between building real wealth and simply earning a high income. If you want to learn more, here is Moment's Guide To Retirement For Entrepreneurs.
In this blog, we're going to break down exactly why this happens, what the IRS is actually offering entrepreneurs in terms of tax-advantaged retirement savings, and what a real plan looks like. The numbers might surprise you, both how far behind many business owners are and how quickly that gap can close with the right structure.
Person Wealth VS. Business Wealth
This is the distinction that changes everything once you truly internalize it, and it's the core reason most high-income business owners arrive at retirement underprepared.
When you reinvest profits back into the business, you are building business value. That's a good thing. But it is also a concentrated bet, a bet that when the time comes, you will be able to sell the business, extract that value, and live comfortably on what's left after taxes, deal fees, and the reality of what buyers are actually willing to pay.
Personal wealth is different. It is what you own independently of whether the business succeeds, sells, or survives. It's the retirement account growing while you sleep. It's the investment portfolio that doesn't care if you lose your biggest client. It's the financial foundation that lets you make business decisions from a position of strength, not desperation.
Most business owners spend 90% of their financial energy building one and almost no energy building the other.
Your Wealth Building Machine
Think about it in terms of compounding. Two business owners, both earning $500,000 per year. One starts aggressively funding a Solo 401(k) at age 35. The other starts at age 48. Assuming a 7% average annual return, by age 65, the difference in that single account can exceed $4.5 million, from the same annual contribution.
Missing years of tax-advantaged contributions is not a minor issue. It is one of the most consequential financial decisions a business owner can make, even when it doesn't feel like a decision at all.
The Service Time Equivalent for Business Owners: Contribution Years
Just like MLB service time determines a player's pension benefits, contribution years determine the foundation of a business owner's retirement. Every year you're eligible to max a retirement plan and don't is a year you can't get back. Here's what that looks like in practice.
The three biggest retirement benefits available to business owners are:
Tax-deferred growth through a Solo 401(k) or SEP-IRA
Tax-free growth through a Roth 401(k) (available inside a Solo 401(k))
Dramatically accelerated contributions through a defined benefit or cash balance plan
Contribution Limits
These numbers are significant. A business owner in the 37% federal bracket who maxes a Solo 401(k) is saving $26,640 in federal taxes in a single year, money that stays invested and compounds rather than going to the IRS.
The right plan depends on your business structure, income, and whether you have employees. Contribution limits vary meaningfully between an S-Corp and a sole proprietorship.
Solo 401(k) vs. SEP-IRA: Which Is Right For You?
Both are powerful. But they are not the same, and the right choice depends on your business structure and income.
Solo 401(k)
Best for sole proprietors, single-member LLCs, and S-Corp owners with no full-time W-2 employees (other than a spouse). The Solo 401(k) allows both an employee deferral and an employer profit-sharing contribution, making it the most powerful savings vehicle available for most self-employed business owners.
Most business owners don't realize their Solo 401(k) can include a Roth designation on the employee deferral portion. This is one of the most underutilized planning tools available to high-income entrepreneurs, and it works differently from a Roth IRA in one critical way: there are no income limits.
A Roth IRA contribution in 2026 phases out at $153,000 for single filers and $242,000 for married filing jointly. Most of our clients are well above those thresholds and cannot contribute to a Roth IRA directly. But a Roth 401(k) has no income limit whatsoever. Any business owner with a Solo 401(k) can designate their employee deferral, up to $24,500 in 2026, as Roth contributions.
The trade-off: Roth contributions are made with after-tax dollars, so you give up the immediate tax deduction. But the growth and all qualified distributions in retirement are completely tax-free, including decades of compounding on a potentially large balance. For business owners who expect to be in a high tax bracket in retirement, or who want tax diversification across their accounts, the Roth 401(k) is worth a serious look.
SEP-IRA
Simpler to administer, but structurally less powerful for most high earners. The SEP-IRA only allows employer contributions, no employee deferral. This limits total contributions at lower net income levels compared to the Solo 401(k).
What Happens After You Max Out Your Retirement Accounts?
Maxing your Solo 401(k) at $72,000 is a significant accomplishment, but for many high-income business owners, it's not enough. If you're earning $500,000, $750,000, or more per year, tax-advantaged accounts alone will not get you to retirement. The math simply doesn't work on the timeline most entrepreneurs need.
This is where a taxable brokerage account becomes one of the most important tools in your financial plan, and one of the most overlooked.
The Taxable Brokerage Account: Your Wealth-Building Layer
A taxable brokerage account has no contribution limits, no income restrictions, and no rules about when you can access your money. You can invest as much as you want, in whatever you want, and withdraw at any time without a penalty. For a high-income business owner who has exhausted their tax-advantaged options, it is the natural next layer of a complete wealth strategy.
The tax treatment is also more favorable than most people realize:
• Long-term capital gains, investments held longer than one year, are taxed at 0%, 15%, or 20%, depending on your income, far below ordinary income tax rates
• Qualified dividends are taxed at the same preferential long-term capital gains rates
• Tax-loss harvesting allows you to strategically offset gains by selling underperforming positions, reducing your tax bill while keeping your portfolio on track
• Unlike a traditional IRA or 401(k), there are no required minimum distributions (RMDs) forcing you to withdraw on the government's schedule
The right investment strategy inside a taxable account matters. Tax-efficient funds, asset location strategy, and disciplined rebalancing all play a role in keeping more of your returns. This is not a set-it-and-forget-it account; it is an active part of your overall tax and wealth plan.
What a Real Retirement Plan for a Business Owner Actually Looks Like
A real plan is not a retirement calculator from a website. It is not a rough idea that you'll figure out when the time comes.
A real plan answers four specific questions:
• How much do I need to retire and maintain my lifestyle?
• What do I currently have outside the business working toward that number?
• What is the gap, and what does the business sale realistically contribute?
• What specific accounts, contribution targets, and milestones close that gap on my timeline?
A critical piece of that plan is an honest business valuation. Business owners almost always overestimate what their company is worth on the open market, and underestimate the taxes, deal fees, and earnout risk that reduce the net proceeds. A plan that relies entirely on a business sale is a plan with enormous risk built in.
The businesses we see sell cleanly and at strong valuations are almost always the businesses whose owners didn't need to sell. They had personal wealth built outside the business, which meant they could be patient, selective, and negotiate from strength.
If you are a business owner who wants a clear answer to what retirement actually looks like for you, schedule a call, and talk with a Moment founder.
