The $757,000 Tax Problem That Started It All
When a successful business owner came to me with a staggering $757,000 tax bill, he was understandably upset.
Despite having a CPA, his business structure was literally lighting his money on fire. His situation is all too common among high-earning entrepreneurs who've outgrown their LLC or S-Corporation structure but don't realize there's a better option.
The client's pre-tax planning situation was straightforward but costly:
W-2 income: $175,000
S-Corp business net profit: $2 million
Real estate portfolio: 14 properties & an office building generating depreciation losses
Federal tax rate: 33.5% (in the highest 37% tax bracket)
⚠️ Warning: If your net operating income is $500K+ and you're in an S-Corporation, you're likely overpaying taxes by hundreds of thousands of dollars every year.
Why S-Corps Become Tax Traps for Million-Dollar Businesses
Most CPAs automatically recommend S-Corporations for small businesses, and for good reason—when you're earning under $250,000 (single) or $500,000 (married filing jointly), they can save you money on self-employment taxes.
However, once you cross these thresholds, S-Corps can become expensive tax traps.
Here's why:
S-Corporation income flows directly to your personal tax return (Form 1040), subjecting all profits to individual tax rates up to 37%. When you're generating millions in profit, this structure forces you into the highest tax brackets, resulting in massive tax bills like my client's $757,000 liability.
S-Corporations cannot be restructured tax-free. So when it comes to selling the Company, if partners disagree on exit strategies, there are very limited options to defer or remove taxes (even when receiving the acquirer’s stock in exchange for your company).
S-Corporations should not have highly appreciating assets due to the built-in gain rules. If you are a savvy business owner (have a net operating income of $500K+ or sold to private equity before), you should never be put in an S-Corporation because you will have to pay taxes on the built-in gains trapped in the S-Corporation.
This is why Fortune 500 companies never use these structures because you trip over self-employment taxes (payroll) and lose sight of the huge giant lurking with income taxes.
S-Corporations formed in a high taxed state (like New York or California). These states have the highest income tax rate for individuals in double digits. Yet the corporate income tax rates are in the single digits. Sounds fair right?
Little to no Qualified Business Asset Income (QBAI - Code Section 199A) means you’re not getting the 20% haircut on business net income flowing into your personal tax return (Form 1040).
QBAI relies on how much the Company pays in wages (Form W-2 pay) and qualified property (like buildings, machinery, and equipment) cost basis at the time of acquisition. So if you are services company or solopreneur, you likely have very little QBAI.
The C-Corporation Solution: From 37% to 21% Tax Rate
The solution was elegant: restructure the business as a C-Corporation. This single change immediately dropped the tax rate from 37% to 21%—a flat rate that applies regardless of income level. This represents an automatic 43% tax savings for high earners in the top bracket.
But we didn't stop there. Within the C-Corporation structure, we implemented three powerful tax strategies:
1. Captive Insurance Company
We established a captive insurance company that the business pays premiums to, creating deductible expenses while building a reserve for business disruption, liability coverage, and healthcare costs not covered by traditional insurance to get reimbursed TAX-FREE!
This strategy alone can create from $100K up to $2.8M in deductions, while protecting the business from unforeseen risks. This can stay with you for life paying medical bills in perpetuity!
2. Executive Bonus Plan
C-Corporations can deduct up to $1 million per executive in compensation. These are VERY common in Fortune 500 companies. We structured an executive bonus plan using a life insurance policy, providing both current tax deductions and future financial security.
The living benefits of the life insurance policy offer additional protection and flexibility as well as large cash balances for retirement (check out how Harbaugh turned $5M into $15M+ from his Michigan coaching contract depending on when he dies).
For a solopreneur with four kids, like my client, this is critical to have on both him and his wife in case of death - either spouse will need financial support to run the business or to pay for a nanny while working.
3. Profit Sharing 401(k) with Cash Balance Plan
This combination of defined benefit retirement plans creates a pre-tax $350,000 annual deduction paid for by the Company (like the old school pension plans that used to exist).
Unlike traditional 401(k)s, profit-sharing plans allow much higher contribution limits, and when combined with a cash balance plan, the tax savings multiply. Plus, these funds can later be converted to Roth accounts for tax-free growth.
W-2 income: $175,000
S-Corp business net profit: $2 million
Real estate portfolio: 14 properties & an office building generating depreciation losses
Federal tax rate: 33.5% (in the highest 37% tax bracket)
✅ Key Insight: The same tax strategies used by Fortune 500 companies are available to successful business owners who know where to look and whom to trust.

The Hidden Investment Opportunity
Beyond the immediate tax savings, we redirected $400,000 into oil and gas investments within his individual tax return. These investments provide:
92.5% first-year tax deductions
25% to 35% average annual cash returns
Projected value with reinvesting income after 10 years: $26 million
This strategy transforms tax savings into wealth-building opportunities, moving business owners from being "rich" (high income, always working) to becoming "wealthy" (assets generating passive income greater than your lifestyle needs).

Don't let another year pass while overpaying taxes. The difference between tax compliance and tax planning could mean hundreds of thousands back in your pocket.
Why Most CPAs Miss These Opportunities
The tax planning strategies used here are the same ones deployed by Fortune 500 companies and billionaires. However, most CPAs:
Are trained in financial statement preparation or tax compliance, not tax planning
Rely on outdated 1986 tax laws instead of 2017 Tax Cuts and Jobs Act and 2025 One Big Beautiful Tax Act provisions
Lack experience with C-Corporation advanced tax planning strategies
Follow a one-size-fits-all approach
Don’t have trusted teams in the funds space with reliable returns where other people invest your money so you print cash while you sleep
This is why major corporations contribute less than 10% to the U.S. Treasury Department’s budget despite generating two-thirds of the U.S. Gross Domestic Product (GDP), while individuals (and thereby pass-through entities) contribute 85%.
Action Steps for Business Owners
If you're a business owner with a net operating income of $500K+ annually, consider:
1. Evaluate your current structure
We established a captive insurance company that the business pays premiums to, creating deductible expenses while building a reserve for business disruption, liability coverage, and healthcare costs not covered by traditional insurance to get reimbursed TAX-FREE!
This strategy alone can create from $100K up to $2.8M in deductions, while protecting the business from unforeseen risks. This can stay with you for life paying medical bills in perpetuity!
2. Run the numbers:
Calculate potential savings by comparing your current Federal effective tax rate to the 21% C-Corp rate (this doesn’t include state taxes).
3. Seek specialized help:
Work with a CPA who specializes in tax planning, not just tax preparation. Stay clear of “Tax Strategists” online because that titles don’t exist in Corporate America.
Look for professionals with Fortune 500 or more than 5 years of Big Four experience in tax planning or mergers & acquisitions. Also, CPAs are more qualified than Enrolled Agents (EAs) in our field, so understand the severity of licenses. EAs don’t understand financial statements and legal structuring like CPAs.
4. Don't wait
C-Corporation formations require 90 days for proper implementation of tax planning strategies. Waiting until Q4 often means deferring benefits to the following year, and thus, no tax savings in the current year.
The Bottom Line
When your CPA generates a 1,030% return on investment on their fees, that's not just tax planning—that's transformation. The same strategies that save Fortune 500 companies billions are available to successful business owners, who know where to look and whom to trust. Not all teams are created equal.
Don't let another year pass while overpaying taxes. The difference between tax compliance and tax planning could mean hundreds of thousands—or even millions—back in your pocket.
