Key Takeaways

  • Loan proceeds aren't considered taxable income because they come with an obligation to repay the money, making them different from earned income in the eyes of tax authorities.

  • Wealthy individuals often use a "Buy, Borrow, Die" strategy. Instead of selling appreciating assets (which would trigger capital gains tax), they borrow against these assets as collateral, accessing cash while avoiding tax events.

  • This borrowing strategy is sustainable because asset appreciation typically outpaces loan interest rates, lenders continuously extend credit as long as collateral value remains high, and the "step-up in basis" at death provides estate planning benefits.

  • Crypto-backed loans offer a practical example of this strategy - borrowing against cryptocurrency holdings allows owners to access liquidity without selling their assets, avoiding immediate capital gains tax while retaining potential upside if the asset appreciates.


Have you ever wondered how some of the wealthiest people seem to live lavish lifestyles without selling off their valuable assets, like stocks or real estate?

It often involves a strategy that uses debt in a way that minimizes their tax burden, particularly capital gains tax.

While loan proceeds themselves aren't typically taxed, the way they are used against growing assets can be a powerful financial tool. Understanding this requires looking beyond simple income and exploring how debt interacts with wealth.

This article aims to demystify these concepts.

1) Are loans taxable income?

But wait, isn't getting a big chunk of cash considered income?

Receiving loan proceeds is fundamentally different from earning income in the eyes of the tax authorities.

When you take out a loan, whether it's a personal loan, a mortgage, or even a casual loan from a friend, you receive cash but also incur an obligation to pay it back. This repayment obligation is key. Because you have to return the principal amount, it's not considered a gain or income.

Essentially, since borrowed money must be repaid, it doesn't count as taxable income.

This principle holds true across various types of loans, though documentation is always important.

  • Personal Loans: Standard personal loans from banks are not taxable income; you don't report the loan amount itself on your tax return.

  • Private / Friend Loans: Loans between private individuals (like friends or family) are also generally not taxable income, provided they are structured as genuine loans with an intention to repay (ideally documented, sometimes with interest depending on the amount to avoid gift tax implications).

  • Business Loans: Similarly, loans taken by a business are liabilities, not income, and are used for business purposes; the loan amount itself isn't taxed as revenue.

Understanding this core concept—that borrowed funds aren't income due to the repayment obligation—is the first step to grasping how loans can feature in sophisticated tax management strategies.

2) How the wealthy use loans against assets

So, how do billionaires use them to seemingly live tax-free?

The ultra-wealthy often employ a strategy sometimes dubbed "Buy, Borrow, Die," leveraging their appreciating assets to access cash without triggering taxes.

Instead of selling assets like stocks or real estate, which would trigger capital gains tax on the appreciation, they take out loans using these assets as collateral. Lenders are happy to offer very low interest rates on these loans because they are secured by valuable, often growing, assets. This borrowed cash is then used to fund their lifestyle or make further investments.

They essentially borrow against their wealth to get cash, avoiding the taxable event of selling.

This method allows them to benefit from their assets' continued appreciation while accessing liquidity tax-efficiently.

The three biggest benefits:

  • Capital Gains Tax Avoidance: The primary advantage is deferring or completely avoiding capital gains tax, which would be due if the assets were sold for profit.

  • Low Interest Rates: Billionaires can often secure loans (like portfolio-backed lines of credit) at interest rates significantly lower than their assets' expected growth rate, making the cost of borrowing relatively small compared to the potential investment returns or tax savings.

  • Continued Asset Growth: By not selling, the underlying assets can continue to grow in value, potentially increasing the owner's net worth even while they are borrowing against it.

This strategic use of loans allows the wealthy to maintain control of their appreciating assets and manage their tax liability in a way unavailable to those relying solely on traditional income.

3) How is this “infinite” debt sustainable?

Okay, borrowing makes sense, but doesn't the debt eventually have to be repaid?

While individual loans have terms, the overall debt burden in this strategy is often managed cyclically rather than being fully paid off during the borrower's lifetime.

The wealthy continue borrowing against growing assets instead of repaying principal, using new loans to cover interest or to repay older loans. Low rates keep costs minimal compared to asset growth. When the borrower dies, heirs can sell assets with a stepped-up tax basis to minimize capital gains.

The debt is often rolled over, serviced by new borrowing against growing assets, and potentially settled by the estate upon death with tax advantages.

Here are three reasons why billionaires borrow:

  • Asset Appreciation Outpaces Debt: The strategy relies on the underlying assets (stocks, real estate, etc.) appreciating at a rate higher than the loan interest rate over the long term.

  • Continuous Borrowing Facility: Lenders are willing to continuously extend credit as long as the collateral value remains significantly higher than the loan amount (maintaining a healthy loan-to-value ratio).

  • Estate Planning Benefits: The "step-up in basis" at death means heirs inherit the assets valued at the time of death; if they sell immediately to pay off the loans, there may be little to no capital gains tax due on the appreciation that occurred during the original owner's lifetime.

Therefore, while it might seem like an "infinite" cycle, it's a carefully managed process reliant on asset growth and favorable loan terms, often culminating in tax-efficient settlement through estate planning.

4) Can regular people use this strategy?

This sounds great for billionaires, but what about the rest of us?

While the core principle of borrowing against assets isn't exclusive to the ultra-rich, applying it effectively on a smaller scale presents significant challenges and risks.

Regular individuals can borrow against assets like home equity (HELOCs) or investment portfolios (margin loans), but typically face stricter loan-to-value requirements than billionaires. The margin for error is much smaller; a market downturn could trigger a margin call on a portfolio loan, forcing asset sales at a loss, while HELOCs carry the risk of losing one's home. Furthermore, the amount available to borrow might not be substantial enough to live off comfortably without taking excessive risk relative to the asset base.

Accessing similar strategies is possible but riskier and less efficient for smaller asset bases due to less favorable terms and lower tolerance for volatility.

Let's consider a more concrete example to illustrate the limitations.

  • Higher Interest Rates: Interest rates on margin loans or HELOCs for average borrowers are usually higher than the sub-1% or low-single-digit rates billionaires might secure, eating into the potential benefit.

  • Margin Call Risk: Borrowing heavily against a smaller portfolio (e.g., $200k) is very risky. A significant market drop (like 30-40%) could force liquidation at the worst possible time to meet margin requirements. Borrowing a small percentage (e.g., $8k-$10k/year as per Q21) might seem safer, but it provides limited cash flow.

  • Loan-to-Value Ratios: Banks typically allow borrowing only up to a certain percentage of the asset's value (e.g., 50-70% for stocks, maybe 80% for home equity), limiting the accessible funds, especially on smaller asset bases.

While borrowing against assets is a tool available to many, replicating the tax-minimization and lifestyle-funding strategy of billionaires is impractical and highly risky without substantial wealth to absorb volatility and secure preferential terms.

5) Can you show me a real-life example?

Theory is great, but how does this actually play out in the real world? Recently, we had John (not his real name), a retired homeowner, wanting to finance the purchase of a house.

John has been holding Bitcoin for years, viewing it as a crucial part of his long-term savings, and he didn't want to part with it. Especially given the significant capital gains taxes he'd face upon selling. As a retiree living primarily on savings and dividends rather than steady employment income, he knew securing a traditional mortgage for the full amount at attractive rates would be challenging. Banks often prefer predictable W-2 income, making his situation less straightforward for conventional lenders.

John faced a dilemma common to those with significant assets but inconsistent income: how to fund a major purchase without selling valuable long-term investments or dealing with traditional lending restrictions.

A crypto-backed loan offers a potential solution, allowing him to tap into his Bitcoin's value without selling, often without the income verification hurdles of traditional banks.

  • Example Loan: John takes out a $500,000 loan from a lender like Lantern against his Bitcoin holdings, perhaps at a 50% Loan-to-Value (LTV) ratio with a 13% fixed interest rate for 12 months.

  • Benefit - Tax Savings: By borrowing $500,000 instead of selling the equivalent Bitcoin, John avoids immediate capital gains tax, potentially saving over $100,000-$150,000 depending on his tax bracket and the asset's appreciation

  • Benefit - Retained Upside: John keeps his full Bitcoin position. If Bitcoin appreciates during the loan term, he benefits from that growth, potentially offsetting or exceeding his interest costs, just like clients who avoid selling before a price increase.

This approach shows how crypto-backed loans can unlock asset value while deferring taxes, similar to traditional asset-backed lending but in the digital space.
