As of November 30, 2025 (about 19 months after the April 26, 2024 episode), there is no U.S. federal law that creates a new, special tax or levy directly on assets held inside 401(k)s, IRAs, or similar private retirement accounts. These accounts remain tax-advantaged under federal law: contributions are generally tax-deferred or deductible, withdrawals are taxed as income, and required minimum distributions continue under long‑standing rules, but there is no new asset-based charge on retirement balances themselves.(en.wikipedia.org)

Recent federal changes since the prediction have mostly expanded or adjusted incentives for retirement saving, not targeted the accounts as a new revenue source. The IRS has increased 401(k) contribution limits for 2025–2026, and retirement-related legislation (including SECURE 2.0’s implementation) emphasizes higher contribution and catch‑up limits and later RMD ages, rather than imposing new wealth-style taxes on retirement accounts.(apnews.com) Major 2025 tax legislation (the so‑called One Big Beautiful Bill Act) focuses on extending or modifying income-tax rates, SALT caps, remittance taxes, and various credits and deductions; public summaries do not show any provision that specifically imposes a new tax on 401(k) or IRA account balances.(en.wikipedia.org)

Although there has been active debate about wealth taxes at both federal and state levels, notable proposals either have not been enacted or explicitly exclude pensions and retirement accounts from their tax base.(nasdaq.com) Because Sacks’s prediction was explicitly about what would happen over the coming decades as federal liabilities grow, and only a short period has passed with no such policy adopted, there is not yet enough elapsed time to conclude that the prediction is either clearly right or clearly wrong. Therefore, the status is inconclusive (too early).
