Unrealized Gain Tax–A Coming Sea Change in FY2025 Budget Proposal?
A US budget proposal to impose a 25% minimum tax on total income, including unrealized capital gains, for households with wealth over $100 million is drawing sharp reactions. Supporters see it as a way to curb “buy, borrow, die” strategies that let the ultra-wealthy live off loans against appreciated assets while paying little income tax, and suggest treating such borrowing as a taxable realization instead. Critics warn of constitutional challenges, forced asset sales, capital flight, and a likely future expansion of the tax to less wealthy groups, and they question whether it would meaningfully address deficits or instead amplify inflation and economic volatility.
Scope and Mechanics of the Proposal
- Several commenters clarify the proposal as: a 25% minimum tax on “total income,” including unrealized gains, for households with wealth above $100M, phasing in fully by $200M.
- Some frame it as a kind of new Alternative Minimum Tax on very high-net-worth households, not a general tax on all unrealized gains.
- Others note that this context is often omitted in media framing, causing confusion and fear among people it likely wouldn’t touch directly.
Fairness, Loopholes, and Alternatives
- Strong focus on the “buy-borrow-die” strategy: ultra-wealthy using appreciated stock as collateral for loans to fund consumption, then passing assets with stepped-up basis so gains are never taxed.
- Multiple suggestions: treat borrowing against assets as a deemed sale and repurchase; tax such loan proceeds as income; or reform step-up in basis at death.
- Some argue these targeted changes would address abuse without taxing all unrealized gains.
Slippery Slope and Threshold Concerns
- Widespread concern that thresholds (e.g., $100M) will drift downward over time via new laws or lack of inflation indexing, citing income tax history, AMT, “mansion taxes,” and sales/Social Security taxes.
- Others challenge the slippery-slope framing, arguing that tax systems evolve with needs and that some taxes haven’t massively expanded.
Economic and Behavioral Effects
- Fears of forced asset sales, market selloffs, capital flight, and pressure on small or illiquid asset holders if thresholds ever widen.
- Counterpoints: even large required asset sales by ultra-wealthy would be a small fraction of total market volume and unlikely to “end the economy.”
- Debate over whether shifting tax burden from top-end wealth to broader public increases total “stuff” produced; some emphasize demand effects and redistribution to lower-income households.
Process and Uncertainty
- One commenter asks how and when budget-linked tax changes take effect and how to track them; response notes Congress can change rates at any time with any effective date, leaving timing and predictability unclear.
