For the better part of a decade, business owners planning their legacies had a countdown clock ticking in the background. The generous estate and gift tax exemption created by the 2017 Tax Cuts and Jobs Act was scheduled to sunset at the end of 2025, cutting the exclusion roughly in half — from nearly $14 million per person back to around $7 million. Families with successful businesses, appreciated real estate, or concentrated stock faced a real risk that assets they had spent a lifetime building would suddenly become exposed to a 40% federal estate tax.
The One Big Beautiful Bill Act (OBBBA) erased that cliff. Beginning in 2026, the exemption is set at $15 million per individual — $30 million for a married couple — and, critically, the law made it permanent and indexed for inflation. For the first time in years, business owners can plan without a looming deadline forcing rushed decisions. Here is what the new rules actually mean, and why “permanent” does not mean “do nothing.”
What Changed — and What Did Not
The headline is simple: more of your wealth passes to your heirs free of federal estate and gift tax. But the details matter for planning.
The 2026 Estate & Gift Tax Rules at a Glance
- Exemption: $15 million per individual / $30 million per married couple.
- Status: Permanent — no scheduled sunset — and indexed for inflation going forward.
- Top estate tax rate: Still 40% on amounts above the exemption.
- Portability: A surviving spouse can still inherit a deceased spouse’s unused exemption (DSUE).
- Annual gift exclusion: Separate from the lifetime amount — roughly $19,000 per recipient in 2026.
- Step-up in basis: Preserved — inherited assets still reset to fair market value at death.
Two things did not change, and both are good news for families. The 40% rate only applies to the portion of an estate above the exemption, so the exemption shelters the first $15 million (or $30 million for couples) entirely. And the step-up in basis survived the negotiations — heirs still inherit assets at their current market value, wiping out unrealized capital gains that accumulated during the owner’s lifetime.
Why This Is a Turning Point for Business Owners
For owners of closely held companies, medical practices, and family real estate, the estate tax has always posed a unique threat: illiquidity. Unlike a stock portfolio, you cannot sell a slice of your practice or your operating business to cover a tax bill. Heirs facing a 40% tax on an illiquid asset have historically been forced into fire sales, hasty borrowing, or breaking up a business their family spent generations building.
With the exemption locked in at $15 million, a large share of privately held businesses now falls entirely under the threshold. That removes the pressure that pushed many owners into complex, expensive structures purely to survive the tax. But it also raises a subtler risk: complacency. A business worth $8 million today can easily be worth $20 million in fifteen years. Knowing what your company is truly worth is the foundation of any plan — which is why a periodic business valuation belongs in every owner’s file.
A permanent exemption removes the deadline, not the responsibility. The families who benefit most are the ones who treat succession as an ongoing plan — not a document they signed once and forgot.
The Planning Moves That Still Matter
“Permanent” is a word Congress has broken before. A future administration could lower the exemption, and even under current law, a growing business can outrun a static plan. Several strategies remain valuable in 2026.
1. Use the Annual Gift Exclusion Every Year
Separate from the $15 million lifetime amount, you can give roughly $19,000 per recipient per year (about $38,000 for a married couple splitting gifts) with no impact on your lifetime exemption at all. Gifting shares of a business or contributions to children and grandchildren year after year quietly shifts wealth — and future appreciation — out of your taxable estate.
2. Lock in Today’s Value on a Growing Asset
If your business is appreciating quickly, gifting or selling equity into a trust freezes today’s value in your estate while future growth accrues to your heirs outside of it. For an owner whose company could triple over the next two decades, this can move millions of dollars of future value beyond the reach of the estate tax — the kind of long-horizon decision our CFO and advisory team models before you commit.
3. Elect Portability When a Spouse Passes
Portability lets a surviving spouse claim the deceased spouse’s unused exemption — but only if an estate tax return is filed to make the election, even when no tax is owed. Missing that filing can forfeit up to $15 million of shelter. It is a paperwork step with enormous consequences, and exactly the kind of detail disciplined financial reporting and compliance is built to catch.
4. Coordinate the Business Succession Plan Itself
The tax exemption is only half the story. Who runs the company after you? How is ownership transferred to the next generation or a key employee? Is there a buy-sell agreement funded and current? These operational questions determine whether a business actually survives a transition, and they should be planned alongside the tax strategy, not after it.
Don’t Forget State Estate Taxes
The federal exemption grabs the headlines, but more than a dozen states impose their own estate or inheritance taxes — often with exemptions far below $15 million, some under $2 million. An estate that owes nothing federally can still face a meaningful state bill. If you own property or operate in multiple states, mapping those exposures is essential, and it pairs naturally with broad tax preparation and strategy that looks past the federal return.
Federal Estate Tax: Then vs. Now
| Feature | If TCJA Had Sunset (2026) | Under OBBBA (2026) |
|---|---|---|
| Exemption per person | ~$7 million | $15 million |
| Married couple | ~$14 million | $30 million |
| Top rate | 40% | 40% |
| Longevity | Scheduled reduction | Permanent, inflation-indexed |
The Bottom Line
The permanent $15 million exemption is genuine relief for business-owning families — it removes a deadline that pushed a generation of owners into rushed, defensive planning. But it does not eliminate the estate tax, it does not protect a rapidly growing business forever, and it does nothing to solve the harder question of how your company actually passes to the next hands. The owners who come out ahead will treat this as breathing room to plan well, not a reason to stop planning.
