The $13.99 Million Question: Why 2025 Is Critical for Estate Planning

With major estate tax changes set for 2025, one client’s story said it best. He waited until the week of a cross-country wedding to buy his plane ticket—only to find the price had tripled. “I got there,” he told us, “but I paid the price for waiting.” For families putting off estate planning, the same lesson applies: procrastination can be costly.

This scenario is a reminder: waiting until the last minute often comes with a cost, especially in estate planning. Acting early offers flexibility, better outcomes, meaningful savings, and far less stress. Waiting until the eleventh hour might still get you there—but it could come at a high cost. For families with estates projected to exceed $7 million (or $13.99 million as a couple), now’s the time to plan.

What is estate tax?

Before exploring what’s changing, it’s important to understand what estate tax is, and why it matters for wealth transfer. The federal estate tax is a tax on the transfer of wealth at death. It applies to the value of an estate passed on to heirs or beneficiaries that exceeds a certain threshold set by law. The tax is assessed on the amount transferred, not on the total assets owned.

Right now, ultra-high-net-worth individuals have a rare opportunity to transfer significant wealth tax-free. But that opportunity is scheduled to shrink dramatically on January 1, 2026. The current lifetime estate and gift tax exemption is set to revert to nearly half that amount if no legislative action is taken.

This sunset presents both a challenge and an opportunity: the challenge of protecting your legacy from unnecessary tax erosion, and the opportunity to act now—while the exemption remains at historic highs—to preserve more wealth for future generations.

Understanding the Sunsetting Estate Tax Exemption

Under the Tax Cuts and Jobs Act of 2017, the estate and gift tax exemption were temporarily doubled. As a result, in 2025, individuals can transfer up to $13.99 million tax-free during life or at death. Couples can protect nearly $28 million. However, this provision expires at the end of 2025. In 2026, the exemption will drop to around $7 million per individual, indexed for inflation if not extended.

Legislative Update: Potential Extension of Elevated Exemption

On May 5, 2025, the House of Representatives passed a budget reconciliation bill that would increase the federal estate tax exemption to $15 million per individual, indexed for inflation going forward. This move—if signed into law—would effectively preserve most of the current high exemption levels beyond 2025, offering continued estate planning flexibility for ultra-high-net-worth families.

However, the bill must still clear the Senate, where its future remains uncertain and subject to potential changes. Until legislation is finalized, the default remains: the exemption is scheduled to drop to approximately $7 million per person on January 1, 2026.

A founder with a $20 million estate might currently be fully exempt. In 2026, $6 million of that estate could become taxable.

The IRS has confirmed that gifts made before 2026 using the elevated exemption won’t be “clawed back” into estates. As clarified in IRS Regulation 20.2010-1(c), individuals who use their full exemption now will not be penalized later if the exemption amount drops. So, using the full exemption now results in a permanent benefit.

What Can You Do?

We see this as a "use it or lose it" opportunity. This moment isn’t just about tax savings—it’s about building or refining a thoughtful estate plan. If you haven’t created one yet, now is an ideal time to begin exploring your options with an advisor. If you already have a plan in place, it’s a chance to ensure it reflects today’s generous exemption and your long-term goals. Strategies that families are pursuing include:

  • Maximize annual gift tax exclusion to children or grandchildren. Individuals can gift up to $18,000 per recipient annually (or $36,000 for married couples) without using any of their lifetime exemption.

  • Irrevocable trusts, or entities designed to permanently move funds outside of one’s taxable estate. These may include structures like Spousal Lifetime Access Trusts (SLATs), which can provide flexibility while reducing estate tax exposure

  • Annual exclusion gifts and tuition/medical payments that don’t count against the exemption

For those with growing businesses, real estate holdings, or investment portfolios, it may be wise to engage an estate planning attorney, tax advisor, and wealth strategist to assess how much future appreciation you could remove from your estate before the exemption is reduced.

Example Estate Tax Impact Before vs. After Sunset (Married Couple)*

Let’s say a married couple has a $20 million estate. Here’s how the numbers stack up:

2025 (Current Law)

  • Exemption per Spouse: $13.99M

  • Total Exempt: $27.98M

  • Taxable Estate: $0

  • Estate Tax Owed: $0

2026 (Current Law, Sunset in Effect)

  • Exemption per Spouse: ~$7M

  • Total Exempt: ~$14M

  • Taxable Estate: $6M

  • Estate Tax Owed: $2.4M

2026 (If Proposed Legislation Passes)

  • Exemption per Spouse: $15M (inflation-adjusted)

  • Total Exempt: ~$30M+

  • Taxable Estate: $0

  • Estate Tax Owed: $0

*Note: Numbers above are for illustrative purposes. Final terms may change. If enacted, the proposed bill would preserve more of today's elevated exemption levels; indexed inflation going forward.

By using the full exemption in 2025 to transfer assets out of the estate, this couple could avoid a potential $2.4 million estate tax liability that would otherwise exist under the reduced 2026 exemption.

Why Planning Ahead Matters

Proactive planning isn’t just about tax efficiency—it’s about aligning your wealth with what matters most: family, legacy, and long-term clarity. As we approach the end of 2025, waiting could invite more than just tax exposure. BakerHostetler notes that delaying planning until the end of 2025 could result in bottlenecks for legal and financial professionals scrambling to handle last-minute requests. In addition, the cost of estate planning services may also increase due to elevated demand.

The closer we get, the more crowded the field becomes—and the fewer seats at the table.

Take the Next Step

If your estate exceeds or could grow above $7 million (or $13.99 million as a couple), this is a valuable time to reassess your estate plan. Taking time to evaluate your plan now can provide more options and reduce the need for rushed decisions later.
