Why a $15M Exemption Is Just the Starting Line for Wealth Protection
The federal estate tax exemption ($15 million per person starting in 2026) creates a dangerous illusion of safety for high-net-worth families. Simply being under the limit is not a plan. True wealth preservation requires understanding critical tax concepts like the step-up in basis and implementing strategies that protect your legacy from taxes, litigation, and mismanagement long after you’re gone.
The Exemption Illusion: More Money, More Problems
While the permanent $15 million exemption (established by the One Big Beautiful Bill in 2025) shields more estates from federal estate tax, it does nothing to address other critical threats to your wealth. A simple will or basic trust is a brittle defense against:
- State Estate Taxes: Florida has none, but if you own property in states like Massachusetts or Oregon, their lower exemptions can trigger significant taxes.
- Capital Gains Taxes: For heirs, the “step-up in basis” is often more valuable than avoiding estate tax. Proper planning ensures they receive this full benefit.
- Creditors and Litigation: An inheritance received outright is vulnerable to a beneficiary’s divorces, lawsuits, and bad decisions.
- Future Legislative Changes: While the current exemption is permanent under current law, future Congresses could reduce it. Proactive planning remains essential.
Estate Tax Exemption 2025-2026: The Critical Role of Basis Planning
For families with highly appreciated assets (real estate, stock, a business), minimizing capital gains taxes is the real game. This is where understanding basis: the original value of an asset for tax purposes, becomes paramount.
The Power of the Step-Up
At death, assets included in your taxable estate receive a “step-up” in basis to their fair market value on the date of death under Internal Revenue Code Section 1014. Your heir can then sell it immediately and owe little to no capital gains tax. This tax forgiveness is a cornerstone of gift and estate tax planning.
How the Step-Up in Basis Works
The step-up in basis is the IRS mechanism under IRC Section 1014 that adjusts the tax basis of an asset to its fair market value on the date of the owner’s death. When an asset is included in your gross estate for tax purposes, its basis is “stepped up” to its date-of-death value before it is distributed to your heirs. The key is ensuring assets are structured correctly to be included in your estate to receive this adjustment.
Consider this illustrative scenario: A couple owns a commercial building purchased for $1 million, now worth $15 million. If they gift it to their children before death, the children inherit the parents’ original $1 million basis (this is called “carryover basis” for gifts). A future sale would trigger approximately $2.8 million in capital gains tax (at current rates). If the children inherit it after death, the basis is stepped up to $15 million, and the capital gains tax on that appreciation is eliminated. The step-up in basis is the process that makes this possible.
Why “Set-It-and-Forget-It” Is a Multi-Million Dollar Mistake
Estate planning for significant wealth is not a one-time event. It’s an active process.
1. The Portability Trap
“Portability” allows a surviving spouse to use their deceased spouse’s unused exemption. But it is not automatic. It requires filing a federal estate tax return (Form 706) within 9 months of death (with a possible 6-month extension), even if no tax is due. Missing this deadline forfeits millions in exemption permanently.
2. The Asset Titling Trap
An asset not properly titled in the name of your trust or structured to be included in your estate may bypass your plan entirely, missing out on the step-up in basis and causing probate complications.
3. The One Big Beautiful Bill Changes
The One Big Beautiful Bill (OBBB), signed into law on July 4, 2025, permanently increased the federal estate and gift tax exemption to $15 million per person ($30 million for married couples) effective January 1, 2026. This amount will be indexed for inflation going forward. While this provides certainty, families should still engage in proactive strategic planning to maximize the benefits of the current exemption and step-up in basis rules.
The Bottom Line: Control Your Legacy’s True Value
Picture this: instead of crossing your fingers that the exemption will protect you, you own the confidence of a plan that actively maximizes every dollar for your heirs. You feel the security of knowing your wealth is shielded from unnecessary taxes and external threats. You see the full value of your life’s work passing efficiently to the next generation, empowering them rather than burdening them with complexity. This is the power of moving beyond the basics.
FAQ: Step-Up in Basis & The Estate Tax Exemption
What is step-up in basis?
Step-up in basis is the IRS process under Internal Revenue Code Section 1014 that adjusts the tax basis of an asset to its fair market value on the date of the owner’s death before it is distributed to an heir. This “step-up in basis” is crucial because it minimizes or eliminates capital gains tax for the heir when they eventually sell the asset. Assets must be included in the decedent’s gross estate to receive this step-up.
Why do wealthy families still need planning with the $15M exemption?
Wealthy families need planning because the exemption doesn’t address state estate taxes, capital gains taxes, or asset protection from beneficiaries’ creditors. Planning ensures assets are structured to receive a step-up in basis, are protected through trusts, and that portability elections are made properly to preserve the full exemption for a surviving spouse. The step-up in basis often provides more value than the estate tax exemption itself for families with highly appreciated assets.
Does the $15M exemption mean I’m protected from all estate-related taxes?
Not necessarily. The $15 million federal exemption (effective January 1, 2026) only protects against federal estate tax. You may still owe state estate tax if you own property in states with their own estate taxes. More importantly, the exemption offers no protection against capital gains taxes for your heirs, which can be a much larger liability if you hold highly appreciated assets. Proper planning around the step-up in basis rules is essential to minimize these tax exposures.
