How the Ultra-Wealthy Legally Minimize Taxes in 2025
In an era of soaring inequality, America’s billionaires continue to amass vast fortunes while paying strikingly low effective tax rates—often lower than those of middle-class workers. As of December 2025, despite ongoing debates and proposed reforms, the U.S. tax code still favors wealth derived from asset appreciation over ordinary wage income. This allows the richest individuals to legally avoid billions in taxes through sophisticated strategies that exploit preferential treatment of capital gains, borrowing, and inheritance rules. 2 “LARGE” 3 “LARGE”
These methods, often requiring teams of accountants and lawyers, are inaccessible to most Americans but remain fully legal under current law.
The Cornerstone: Buy, Borrow, Die
The most powerful strategy, popularized as “Buy, Borrow, Die,” enables the wealthy to live luxuriously without triggering taxable income.
- Buy: Acquire appreciating assets like stocks, real estate, or art. Unrealized gains—the increase in value while holding the asset—are not taxed. 0 “LARGE” 1 “LARGE”
- Borrow: Instead of selling assets (which would realize gains and incur taxes), borrow against them. Loans are not considered taxable income, and interest rates are often low for high-net-worth individuals.
- Die: Upon death, heirs receive a “stepped-up basis,” resetting the asset’s cost basis to its current market value. This erases decades of unrealized gains for tax purposes.
As of late 2025, this strategy remains intact. Proposals to tax unrealized gains (like the Billionaires Income Tax Act) or impose excise taxes on asset-backed loans (such as the ROBINHOOD Act) have been introduced but not enacted. The “One Big Beautiful Bill” signed in July 2025 extended many 2017 tax cuts, further benefiting investors without closing these loopholes.
Preferential Treatment for Capital Gains
When assets are sold, long-term capital gains are taxed at rates of 0%, 15%, or 20%—far below ordinary income rates up to 37%. Many ultra-wealthy individuals minimize even this by rarely selling, deriving wealth primarily from asset growth rather than salaries.
Real Estate: Depreciation and Deferral
Real estate investors deduct “depreciation”—a paper loss reflecting wear and tear—even as properties appreciate in value. 5 “LARGE” 6 “LARGE”
Tools like 1031 exchanges allow deferral of gains by swapping properties, and bonus depreciation accelerates write-offs.
Charitable Contributions and Foundations
Donating appreciated assets provides deductions at fair market value while avoiding capital gains taxes. Private foundations allow control over distributions and ongoing tax benefits. 7 “LARGE” 8 “LARGE”
Trusts, Estate Planning, and Other Tools
Advanced trusts (e.g., GRATs) transfer wealth with minimal gift taxes. Tax-loss harvesting offsets gains, and pass-through businesses deduct expenses generously.
The Bigger Picture: Inequality and Reform Efforts
Analyses show billionaires often pay effective rates below 5% on wealth growth, exacerbated by a system taxing realized income rather than net worth. The 2025 extension of TCJA provisions preserved many advantages, though state-level reforms and IRS enforcement have increased scrutiny.
Critics argue these strategies widen the wealth gap, prompting calls for taxing unrealized gains or ending stepped-up basis. Yet as 2025 ends, core mechanisms persist, allowing generational wealth to grow largely untaxed.
These are legal tax avoidance techniques, not evasion. For personalized strategies, consult a qualified tax professional, as laws continue to evolve.
