Your $13.61M Estate Tax Exemption Drops to ~$7M in 326 Days

You have 326 days to decide what to do about a $6.6 million tax planning opportunity — and the clock started the moment you opened this article.

The Tax Cuts and Jobs Act of 2017 temporarily doubled the federal estate tax exemption. In 2025, that exemption sits at $13.61 million per individual ($27.22 million for married couples). On January 1, 2026, absent Congressional action, it reverts to approximately $7 million per person, adjusted for inflation from the pre-2018 baseline.

That's not speculation. It's written into the law itself — a sunset provision that Congress built in to make the budget math work.

For retirees who've accumulated significant assets through a lifetime of saving, business ownership, or real estate appreciation, this isn't abstract tax policy. It's a concrete decision point that could mean the difference between your heirs receiving your full legacy or writing a seven-figure check to the IRS.

Here's what you need to understand about the exemption change, why the timing matters more than you might think, and the strategic trade-offs involved in acting now versus waiting.

Understanding the $6.6 Million Gap

The federal estate tax applies to the total value of your estate at death — including real estate, investment accounts, retirement funds, life insurance death benefits, and business interests — minus debts and certain deductions. Anything above the exemption threshold gets taxed at 40%.

In 2025, a married couple can pass $27.22 million to heirs completely free of federal estate tax. Starting in 2026, that drops to roughly $14 million (approximately $7 million per spouse, indexed for inflation).

The math on the gap is straightforward:

• 2025 exemption (married): $27.22 million
• 2026 projected exemption (married): ~$14 million
• Potential additional taxable estate: ~$13 million
• Potential additional estate tax at 40%: ~$5.2 million

For individuals, the numbers are half that — but still substantial. A single person with a $13 million estate pays zero federal estate tax if they die in 2025. If they die in 2026 with the same estate value, their heirs could owe roughly $2.4 million.

According to IRS data, only about 0.2% of estates currently owe federal estate tax. But that percentage will increase significantly when the exemption drops, pulling estates valued between $7 million and $13.61 million into taxable territory.

It's worth noting: these figures apply to federal estate tax only. Twelve states plus the District of Columbia impose their own estate taxes, often with much lower exemption thresholds. Maryland and Massachusetts, for example, exempt only $1 million per person.

The Irrevocable Trust Strategy — And Its Trade-Offs

The primary strategy for locking in the current higher exemption involves transferring assets to an irrevocable trust before December 31, 2025.

Here's why this works: The IRS has confirmed through Treasury Regulation 20.2010-1(c) that gifts made under the higher exemption won't be "clawed back" if the exemption later decreases. If you gift $10 million to an irrevocable trust in 2025 using your lifetime exemption, that gift remains protected even after the exemption drops to $7 million.

This creates a genuine opportunity — but it comes with significant constraints:

• Irrevocable means irrevocable. Once assets are in the trust, you generally cannot take them back or change the terms. If Congress extends the higher exemption (not impossible given election-year politics), you've given up control of assets you might have preferred to keep.
• Loss of step-up in basis. Assets transferred to certain irrevocable trusts may not receive a stepped-up cost basis at death, potentially creating larger capital gains tax bills for heirs when they sell.
• Complexity and cost. Properly structured irrevocable trusts (like Spousal Lifetime Access Trusts, or SLATs) require experienced estate planning attorneys, often costing $5,000 to $15,000 or more to establish.
• Income tax considerations. Depending on trust structure, income generated by trust assets may be taxed at compressed trust tax brackets, which reach the top 37% rate at just $15,200 of income in 2025.

Many estate planning professionals suggest a wait-and-see approach through mid-2025, monitoring Congressional activity before committing to irreversible transfers. The risk: if you wait too long and Congress doesn't act, you may not have time to execute complex trust strategies before year-end.

Who Actually Needs to Worry About This

Not every retiree needs to restructure their estate plan over this change. The question is whether your estate — calculated correctly — might exceed the lower exemption threshold.

Many people underestimate their estate size because they're thinking about liquid assets only. Your taxable estate includes:

• Retirement accounts (401(k)s, IRAs, pensions) — the full balance, not the after-tax value
• Real estate at fair market value, including your primary residence
• Life insurance death benefits if you own the policy
• Business interests at appraised value
• Investment and bank accounts
• Personal property (vehicles, jewelry, collectibles)

A couple with a paid-off $1.5 million home, $3 million in retirement accounts, $2 million in taxable investments, a $1 million life insurance policy, and a small business worth $2 million has a $9.5 million estate. Today, that's comfortably under the exemption. In 2026, they could face estate tax on approximately $2.5 million — a potential $1 million tax bill.

Research from the Federal Reserve's Survey of Consumer Finances indicates that households headed by someone aged 65–74 have median net worth of approximately $410,000 but mean net worth of $1.79 million — reflecting how a smaller number of higher-wealth households skew the average. If you're reading this article, you may be closer to the mean than the median.

Timing Decisions When the Future Is Uncertain

The fundamental challenge with 2025 estate planning is that nobody knows what Congress will do. Three scenarios are plausible:

Scenario 1: Full extension. Congress extends the higher exemption permanently or for another decade. If you've already transferred assets to an irrevocable trust, you've given up flexibility for no tax benefit.

Scenario 2: Full sunset. The exemption drops to ~$7 million as scheduled. Those who acted early preserved their wealth transfer opportunity; those who waited face a larger taxable estate.

Scenario 3: Compromise. Congress sets a new exemption somewhere between $7 million and $13.61 million — say, $10 million. This middle ground would reduce but not eliminate the urgency.

Election-year politics add another layer of uncertainty. Tax policy could shift significantly depending on November 2024 results and subsequent legislative priorities.

Given this uncertainty, many estate planning professionals recommend preparing documentation and strategy in Q2–Q3 of 2025, with execution timed for Q4 once Congressional direction becomes clearer. This approach balances preparation with flexibility — though it requires accepting that a last-minute rush could create its own complications.

When the first spouse dies, any unused estate tax exemption can transfer to the surviving spouse through a portability election on a timely filed estate tax return (Form 706). This must be filed even if no estate tax is owed.

Many families skip this filing because no tax is due, permanently losing access to the deceased spouse's exemption. With exemptions potentially dropping to $7 million, that lost portability could mean $2.8 million in additional taxes (40% of $7 million) when the surviving spouse eventually dies.

If you've lost a spouse in recent years and didn't file Form 706, you may still have options — consult with a qualified estate planning attorney about late portability elections.

Key Takeaways

• The federal estate tax exemption drops from $13.61 million to approximately $7 million per person on January 1, 2026, unless Congress acts.
• Gifting assets to an irrevocable trust before year-end 2025 can lock in the higher exemption permanently, but these transfers cannot be undone.
• Your taxable estate likely includes more than you think: retirement accounts, life insurance death benefits, and real estate all count at full value.
• The IRS has confirmed no "clawback" of gifts made under the higher exemption, even after it decreases — per Treasury Regulation 20.2010-1(c).
• Many advisors recommend preparing estate planning strategies in mid-2025 while waiting for Congressional clarity before executing.
• Portability elections preserve unused exemption between spouses but require filing Form 706 — even when no tax is owed.
