How the Wealthy Use “Buy, Borrow, Die”—and Why They Still Pay Taxes

The phrase “the rich don’t pay taxes” is too broad. A more accurate description is that some wealthy investors can choose when to realize gains, borrow against appreciated assets instead of selling them, and plan how assets transfer at death. Those moves can defer or reduce some income taxes under current law, but they do not make taxes, debt, risk, or repayment disappear.

What “buy, borrow, die” actually means

In a taxable brokerage account, an investor generally does not owe capital-gains tax merely because a stock has risen in value while it is still held. Tax usually comes into the picture when a taxable sale or other realization event occurs. Dividends and interest can still be taxable along the way, and special rules can apply to particular assets and taxpayers. The IRS describes investment income and reporting gains from sales in Publication 550 and Topic 409.

Selling appreciated shares to fund a purchase may realize a gain. Pledging eligible shares as collateral and taking a bona fide loan may provide cash without selling those shares. Loan proceeds are generally not income because the borrower has an obligation to repay; if the debt is later forgiven or discharged, cancellation-of-debt income may arise, subject to exceptions. See IRS Topic 431.

How borrowing against investments works

A bank or brokerage may lend against a portfolio under a securities-backed line of credit, margin loan, or another secured-credit agreement. The lender sets which assets qualify, how much it will lend, the rate, advance rate, collateral requirements, and what triggers a demand for more collateral or repayment. The shares remain pledged and subject to the contract.

The advantage is timing: the borrower gets liquidity without immediately selling an appreciated position. That may defer recognition of a gain, but borrowing creates a liability and interest cost. Personal interest is generally not deductible, and mixed-purpose debt may require allocating interest according to how borrowed money is used. Do not assume a loan secured by investments automatically makes its interest deductible; Publication 550 discusses allocation and limits.

The strategy is sometimes described as “the portfolio earns more than the loan costs.” That can happen over a particular period, but it is not guaranteed. An expected return is not contractual, and comparing an uncertain gross return with a known borrowing rate leaves out fees, taxes on dividends, volatility, and the risk of a forced sale.

Why “die” matters—and what it does not erase

Under current federal law, inherited property generally receives a basis equal to its fair market value on the date of death, or an allowed alternate valuation in some estate-tax filings. This can reduce taxable gain if an heir later sells property that appreciated during the decedent’s lifetime. It is often called a “step-up in basis,” though basis can also move down if value declined. The IRS summarizes the rule and exceptions in Publication 559.

That is not a blanket exemption for every asset or transfer. Exceptions include certain property transferred shortly before death and special rules for income earned but not yet recognized. Estate tax may apply under the law and exclusions for the year of death; state estate or inheritance taxes may also matter. An estate’s debts and costs do not vanish. The estate may use cash, sell assets, refinance, or otherwise settle obligations, and heirs receive what remains under the governing documents and law.

Nor is every wealthy person following this playbook. Some pay income tax on wages, business income, dividends, interest, realized gains, rental income, and other taxable events. They may also pay property, payroll, sales, and other taxes. The strategy manages timing and character of particular tax events; it does not put someone outside the tax system.

Why the approach is easier for very wealthy investors

Access depends on eligible collateral and a borrower who can handle the debt if markets turn. A wealthy borrower may have diversified assets, other cash flow, and the ability to repay without selling pledged shares. A household with a small or concentrated portfolio may have little borrowing capacity and no spare liquidity for a collateral call. A lender can change eligible collateral or terms, and rates may rise.

Interest, fees, and repayment still have to come from somewhere. If a portfolio falls while debt remains, leverage magnifies the decline in net worth. For securities in a margin account, the SEC warns a broker may sell securities to meet a maintenance requirement, potentially without first giving the investor time to respond. A non-margin securities-backed line has its own contract and call provisions; read it rather than assuming the rules are identical.

There is policy and planning risk too. Basis rules, estate-tax rules, interest deductibility, and state treatment can change. A careful plan models flat returns, higher rates, a lender calling the loan, a longer-than-expected life, and heirs who need to sell assets to settle the estate.

What to take away

• Unrealized appreciation is generally not taxed as a capital gain until a realization event, but dividends and other income may be taxable sooner.
• A bona fide loan can provide liquidity without a sale, but brings interest, collateral, and repayment obligations.
• Inherited property generally gets a new basis under current federal law, with exceptions and possible estate or state taxes.
• “Never repay” is misleading: debts survive the borrower and must be addressed by the borrower or estate.
• The strategy depends on substantial assets, lending access, planning, and capacity to absorb downside. It is not guaranteed or universal.
