The Inheritance Secret: How Stepped-Up Basis Eliminates Capital Gains Tax
π Passing Wealth Across Generations Tax-Free
Imagine you've built a $50 million fortune over your lifetime. You want to pass it to your children. But there's one concern: "How much tax will they have to pay?"
If you live in the United States, the answer might surprise you: "Potentially zero." This is the final and most powerful step of the Buy-Borrow-Die strategy.
Today, we're exploring the secret that allows the wealthy to transfer generational wealth without tax burden: the Stepped-Up Cost Basis.
π What is Stepped-Up Cost Basis?
Stepped-up basis is a unique feature of U.S. tax law. Simply put, the cost basis of inherited assets resets to the market value at the time of the original owner's death.
Understanding Through Examples:
Scenario A: Gifting While Alive
- Father bought stock in 2000 for $10 million
- Current value in 2024: $50 million
- Father gifts it to son while alive
- Son immediately sells for $50 million
Tax Calculation:
- Capital gain: $50M - $10M = $40 million
- Capital gains tax (~20%): $8 million
Scenario B: Inheriting After Death
- Father bought stock in 2000 for $10 million
- Value at death in 2024: $50 million
- Son inherits the stock
- Cost basis resets to $50 million (stepped-up basis)
- Son immediately sells for $50 million
Tax Calculation:
- Capital gain: $50M - $50M = $0
- Capital gains tax: $0
Same $50 million asset, but the difference between gifting and inheriting creates an $8 million tax difference.
π Buy-Borrow-Die: The Complete Picture
Now the entire puzzle comes together. Do you see why the wealthy never sell their assets?
The Full Cycle:
Step 1 (Buy): Parent Generation
- Purchase $10 million in stocks
- Never sell for 30 years
- Value grows to $50 million
Step 2 (Borrow): Parent Generation
- Living expenses covered through SBLOC
- Can borrow up to 50% of $50M portfolio = $25 million
- Zero taxes, interest offset by portfolio growth
Step 3 (Die): Transfer to Next Generation
- Parent dies, $50 million portfolio passes to children
- Cost basis resets to $50 million
- Children can now restart the cycle from Step 1 with no tax concerns
The Compounding Effect
This isn't just a one-generation story. Children can use the same strategy, as can grandchildren. Wealth compounds exponentially across generations, and with each transfer, the cost basis resetsβkeeping tax liability at zero.
π‘ John vs Viv: 30 Years Later
Let's revisit the comparison from the original script with more depth.
John: Traditional Approach
- 2024: Sells entire $10 million portfolio
- Pays $4 million in taxes
- Cash in hand: $6 million
- Lives on and spends $6 million
- 30 years later: Portfolio value $0
- Passes to children: Almost nothing
Viv: Buy-Borrow-Die Approach
- 2024: Keeps $10 million portfolio
- Takes $6 million SBLOC loan (5% interest)
- Taxes: $0
- Lives on and spends $6 million (same as John)
- Portfolio continues growing at 8% annually (30 years)
- 30 years later: Portfolio value approximately $100 million
- Passes to children: $100 million (stepped-up basis = zero tax)
Same $6 million spent, but 30 years later, the results are worlds apart.
π What About Other Countries?
Unfortunately, stepped-up basis is unique to the U.S. tax code. Other countries have different structures.
Countries Without Stepped-Up Basis:
- UK: Inheritance tax on estate value
- Germany: Inheritance tax with exemptions
- Canada: Deemed disposition at death (capital gains triggered)
- Australia: No inheritance tax, but capital gains on disposal
Can the Principles Still Apply?
While not identical, the underlying principles can be adapted:
- Use allowable exemptions: Most countries have estate tax thresholds
- Trust structures: Professional planning can minimize taxes
- Leverage during lifetime: Use home equity or margin loans
- Tax-efficient accounts: Pensions, ISAs, 401(k)s, etc.
The core principle remains: minimize taxes while transferring assets to the next generation.
π― The True Power of Stepped-Up Basis
1. Permanent Tax Avoidance
Most tax strategies focus on "pay taxes later." Stepped-up basis says "never pay taxes." It's not deferralβit's elimination.
2. Generational Wealth Acceleration
If the first generation builds $10M β $50M, the second generation can build $50M β $250M. With compound growth and zero tax drag, exponential wealth accumulation becomes possible.
3. Justification for Asset Concentration
"Why not diversify out of stocks?" The answer: If you never sell, there's no tax, and at death the basis resets. It becomes rational to concentrate assets and hold long-term.
βοΈ Fairness Debate and Policy Changes
This strategy is legal, but many consider it "unfair."
The Criticism:
- Progressive tax avoidance: Wealthy pay lower effective rates
- Opportunity inequality: Only accessible to asset holders
- Revenue loss: Negative impact on government finances
Policy Change Possibilities:
The Biden administration proposed eliminating stepped-up basis multiple times, but it hasn't passed yet. However, future law changes are possible.
What's available today may not be available forever.
π Practical Checklist
To utilize the stepped-up basis strategy:
β Requirements:
- Quality long-term assets (stocks, real estate)
- Ability to use collateral loans for living expenses
- Safety margin to survive asset value declines
- Professional advisors (CPA, attorney, financial planner)
β Cautions:
- Avoid excessive leverage
- Maintain cash reserves for volatility
- Regular portfolio rebalancing
- Monitor legislative changes
β Key Takeaways
- Stepped-Up Basis: Inherited assets reset to market value at death
- Zero Capital Gains: Immediate sale after inheritance has no taxable gain
- Generational Wealth Transfer: Each generation resets basis with no tax burden
- Completes Buy-Borrow-Die: Buy, borrow, die creates the perfect tax-avoidance cycle
- U.S.-Specific: Other countries require different strategies
Stepped-up basis isn't just a tax trick. It's a system for preserving and amplifying wealth across generations.
You don't need tens of millions to start. What matters is understanding the principles and applying them to your situation.
Start small. Buy stocks, hold them long-term, leverage when needed, and pass them to your children. That's true generational wealth.
