Most people understand money through one lens: earn it, pay taxes on it, save what’s left, and hope the remainder compounds into something meaningful over time. That framework is not wrong, exactly. It’s just incomplete, and the incompleteness is not accidental. The rules that govern how wealth is built, borrowed against, and transferred across generations were not written with the average worker in mind. They were written by and for people who already own things.

The strategy explored here is entirely legal. It has existed in the tax code for decades. It is used routinely by high-net-worth families, real estate investors, and corporate executives. And yet the vast majority of working Americans have never heard of it, let alone been given the opportunity to consider whether any part of it applies to their own financial situation. That information gap is itself a form of structural disadvantage.

What follows is a close examination of how this strategy actually works – mechanically, legally, and practically – and what ordinary investors can reasonably take from it.

The Framework: Three Steps, One Cycle

The phrase “buy, borrow, die” was coined by Edward McCaffery, a law professor at the University of Southern California, in the mid-1990s to help students understand how wealthy people approach taxation. The label sounds blunt, but the underlying mechanics are precise.

The strategy is not technically a loophole. It is a legal approach that takes advantage of how different parts of the tax code work together, combining three existing rules: capital gains are only taxed when assets are sold, loan proceeds are not taxed as income, and inherited assets receive a “stepped-up basis” that erases capital gains tax liability.

Wealthy households can use this three-step strategy to get significant capital gains tax advantages, protecting the inheritance of wealth and allowing the very wealthiest families to hold, live off of, and transfer that wealth without ever paying taxes on it, and it is all legal.

Understanding why requires walking through each phase carefully.

Phase One: Buy Assets That Appreciate

The first step is to accumulate assets with high growth potential, typically investments like stocks, bonds, real estate, private equity, or valuable collectibles. The key is that these assets are held for the long term, allowing their value to compound significantly over decades. Unlike earned income such as salaries and wages, which is taxed annually, the appreciation of these assets is generally not taxed until they are sold.

This distinction matters enormously. A salaried employee pays income tax on every dollar earned. An investor who watches a stock portfolio triple in value over ten years pays nothing on that growth until the moment of sale. Under IRC Section 1001, a taxable event occurs only upon a realization event such as a sale or exchange. This means an investor can hold a portfolio worth millions in unrealized gains without owing a single dollar in capital gains taxes.

The very wealthy typically do not receive their wealth in the form of weekly paychecks or regular salaries. Instead, very high-net-worth individuals often store most of their wealth in assets like stocks, real estate, and operating businesses, a type of wealth that avoids capital gains taxes because it is not considered income until it is sold or “realized.”

The practical takeaway here is straightforward. Prioritizing assets that appreciate over time, rather than simply accumulating cash savings, is the foundational move. The tax advantage begins the moment you choose ownership over consumption.

Phase Two: Borrow Against What You Own

This is where the strategy diverges sharply from conventional financial thinking. Most people, when they need liquidity, sell something. The wealthy, when they need liquidity, borrow against something.

In the case of someone borrowing against appreciated assets, loan proceeds function identically to cash from an asset sale, except without the associated tax liability. The IRS does not treat borrowed money as income. A wealthy family does not owe taxes on its asset-leveraged loans because the government does not tax borrowed money.

The proceeds from a cash-out refinance, for example, are not taxable. The money received is a loan taken out against a home’s equity, one that will be paid back. The IRS considers the cash from a cash-out refinance as a loan, not income. Therefore, it is not subject to income tax. Essentially, the borrower is borrowing against equity already built, and loans are not considered income under tax law.

Consider a concrete example. An investor owns a property now valued at $500,000 with an outstanding mortgage balance of $280,000. A lender willing to refinance up to 75% of the property’s value would create a new loan of $375,000. After paying off the remaining $280,000 balance, the investor pockets approximately $95,000 in cash. None of that cash is taxable income. It is debt, not earnings, and the underlying asset continues to appreciate.

Private banking loans allow very wealthy people to borrow against all their assets, including property, businesses, and investments. Real estate loans such as cash-out refinancing, home equity lines of credit, and commercial property loans let people borrow against property value without selling. These methods provide cash without triggering capital gains tax, and the loan proceeds are not counted for income tax purposes.

Many wealthy people pay only the interest on their loans rather than the principal, keeping the debt active for many years. Some refinance their loans periodically as their assets grow in value, taking out new and larger loans to pay off the old ones.

For anyone curious about how this intersects with broader investment strategies used by the ultra-wealthy, the reasons billionaires prefer holding assets over selling are rooted in this same logic: selling triggers taxes, holding creates options.

Securities-Based Lending: The Parallel Track

The same principle that applies to real estate applies to investment portfolios. This strategy is called securities-based lending. With a securities-backed line of credit, firms like JP Morgan, Wells Fargo, or private banks will lend 70% to 90% of a portfolio’s value, using stocks, bonds, or mutual funds as collateral.

The total outstanding securities-based lending market reached approximately $138 billion as of Q1 2024, according to research from the Federal Reserve. These loans give borrowers access to funding without having to liquidate their portfolios, and they carry flexible repayment terms and tax benefits.

According to an analysis by Americans for Tax Fairness of Federal Reserve data on household income and wealth, America’s billionaires and centi-millionaires, those with at least $100 million of wealth, collectively held at least $8.5 trillion of unrealized capital gains in 2022, profits from unsold investments that constitute the largest source of income for the super-rich.

The borrowing phase has real costs. Interest must be paid. Rates fluctuate with market conditions. Borrowing against assets can reduce financial flexibility, since payments must continue even during market downturns or personal financial setbacks. Missing payments on loans backed by real estate can lead to foreclosure, and missing payments on loans backed by investment portfolios can result in liquidations or margin calls. These are not theoretical risks – they materialize during market dislocations.

Phase Three: Die With the Assets (And Pass Them Tax-Free)

The final phase is where the most powerful and most contested element of the strategy comes into play. It is also the most misunderstood.

According to Section 1014 of the Internal Revenue Code, if a person holds property at death, it will receive a new basis equal to the fair market value of the property at the date of death. In the case of appreciated assets, this rule allows people to inherit assets such as stocks or real estate without inheriting the tax burden triggered by capital gains. This is known as a step-up in basis.

What that means in practice is this: an investor who bought a stock for $20,000 and watched it grow to $500,000 over thirty years would owe capital gains tax on $480,000 of appreciation if they sold it. But if they hold the asset until death, their heirs generally receive a step-up in basis automatically, resetting the cost basis to the property’s fair market value on the date of death under IRC Section 1014. This wipes out the unrealized appreciation that occurred during the original owner’s lifetime, so if the heir sells the asset close to its value at death, there may be little or no capital gains tax due.

For a beneficiary who inherits a home that appreciated by $400,000 over decades, the step-up can eliminate tens of thousands of dollars in capital gains tax that would otherwise come due at sale.

Neither the current federal nor local tax code requires the original asset holders or their heirs to pay taxes on the growth in value up to that point. Instead, the tax code wipes out any tax liability for capital gains by “stepping up” the baseline value of the assets from the original price to their value at the time of the benefactor’s death, enabling wealthy families’ heirs to avoid taxes on the increased value of stocks, real estate, and valuable artwork.

The outstanding loans taken during the “borrow” phase are repaid from the estate. In this strategy, the individuals who inherit the estate can use some of the assets passed on to pay off outstanding loans, which allows them to avoid settling those debts out of their own pockets. Additionally, heirs benefit from a step-up in the cost basis of those assets once they receive them, allowing them to avoid any capital gains tax due on the sale of assets they inherit.

What the Numbers Actually Look Like at Scale

The tax implications of this strategy playing out across tens of thousands of wealthy households are not trivial. According to the Americans for Tax Fairness analysis of Federal Reserve data, America’s billionaires and centi-millionaires collectively held at least $8.5 trillion of unrealized capital gains in 2022, and those profits from unsold investments constitute the largest source of income for the super-rich.

More than one in every six dollars, or 18%, of the nation’s unrealized gains is held by roughly 64,000 ultra-wealthy households, who make up less than 0.05% of the population, nearly triple the share that billionaires and centi-millionaires held when the Federal Reserve started tracking unrealized gains in 1989.

The ultra-wealthy do not need to sell to benefit from this wealth: they can live off low-cost loans secured against their growing fortunes, and once those assets are inherited, the gains disappear completely for tax purposes.

Who This Strategy Actually Works For

The Buy, Borrow, Die strategy is a tax planning approach that wealthy people use to pay less in taxes and grow their money. It uses current tax laws to delay or avoid taxes, especially on investment profits. It is typically associated with high-net-worth individuals, but even among the wealthy, it is not right for everyone.

The largest drawback is that a person must already be wealthy to start using this strategy. Without a large enough portfolio, no lender will provide enough credit to live on for extended periods. Another major constraint is that retirement plans such as IRAs and 401(k)s cannot be used as collateral. If someone is a high earner who used such plans to reduce taxes while building wealth, their taxable portfolio may be too small to make the strategy work effectively.

Despite its tax advantages, the strategy is not as widely used as many assume, even among the wealthy. Recent research by economists Zachary Liscow from Yale and Ed Fox from Michigan found that the strategy is not as popular as previously believed. The biggest reason most wealthy people rarely use this strategy is that they typically have enough cash flow from dividends, interest, business income, or salaries to cover their living expenses without needing to borrow or sell assets.

That does not, however, mean the strategy has nothing to offer ordinary investors. It is not just for billionaires. Everyday investors use the same fundamental approach with brokerage accounts, real estate, and small businesses.

The tax code rules that underpin this strategy apply equally to a person with a $200,000 rental property and a person with a $200 million portfolio. A step-up in basis works the same way regardless of estate size. A common misunderstanding is that the step-up is limited to large or taxable estates. An estate worth $500,000 gets the same basis adjustment as one worth $50 million. The only requirement is that the property was acquired from a decedent within the meaning of the statute. No estate tax return needs to be filed for the step-up to apply.

The Political and Legislative Debate

Section 1014 is perennially on the chopping block in Washington. It is one of the most significant and polarizing provisions in the tax code. Proponents of repealing the stepped-up basis argue that it is fundamentally unfair, labeling it the “Angel of Death” loophole and contending that it allows the wealthiest families to pass on billions of dollars in untaxed capital gains, exacerbating wealth inequality.

While reforms designed to include loan proceeds in taxable income, for example treating borrowing as a deemed realization event, would generate some revenue, with Yale estimating between $102 billion and $147 billion over ten years, their potential is “somewhat limited in their revenue potential compared with more fundamental reforms of capital income taxation.” Still, the Yale Budget Lab concludes that “from a first-principles perspective, policy changes aimed at limiting buy-borrow-die are a natural place for reform in the current tax code.”

Congress has taken notice, and bills have been introduced to limit or eliminate the step-up in basis. There have even been bills intended to tax investors when they access equity in an asset via a loan. Those bills have all failed. For now, Buy, Borrow, Die remains one of the most powerful and legal wealth-building and tax-saving strategies available.

While recent legislation preserved the stepped-up basis provision, future legislative sessions could still target this rule. Past proposals have suggested a carryover basis system or a deemed realization event at death, though none have been enacted. The permanence of the current exemption does not guarantee the step-up’s permanence, making it important to stay current with tax law developments and maintain flexible estate plans.

What This Actually Means for You

The Buy, Borrow, Die strategy is not a secret in the sense of being hidden. Its components are written openly into the Internal Revenue Code. What makes it functionally inaccessible to most people is a combination of asset thresholds, lending relationships, and the kind of long-horizon planning that becomes possible only when someone is not living paycheck to paycheck.

But the underlying principles carry real lessons for anyone building wealth at any level. First, assets that appreciate without triggering taxes while you hold them are fundamentally more tax-efficient than earned income. Second, borrowing against an appreciating asset, rather than selling it, preserves both the asset’s growth potential and avoids a capital gains event. Third, estate planning that accounts for stepped-up basis under IRC Section 1014 can result in meaningful tax savings for heirs, regardless of estate size.

Because the strategy relies on maintaining and passing on significant assets, it is not realistic for many investors as a whole system. It also does not replace the need for a diversified financial plan. Even high-net-worth households may benefit from tax-advantaged retirement accounts, insurance, and traditional savings strategies that reduce risk. No single tax strategy constitutes a complete financial plan, and anyone considering any of these approaches should work with a qualified tax advisor or estate planning attorney before acting.

The broader point is this: the tax code rewards asset ownership in ways it does not reward labor. Knowing that is not enough to change your circumstances overnight. But understanding the mechanics is the necessary first step toward making decisions that are more aligned with how wealth actually accumulates, and less aligned with how most of us were taught to think about money.
