The 2026 Federal Estate Tax Sunset: What Just Changed for Northern Virginia Families and What to Do Now

By Anthony I. Shin, Esq. | Estate Planning & Civil Litigation | Shin Law Office

What Just Changed

From 2018 through the end of 2025, the federal estate and gift tax exemption sat at its highest level in modern history under the 2017 tax law that doubled the prior exemption. For most of that period, only the wealthiest 1% of American households faced federal estate tax exposure, and most working professional families in Northern Virginia, even at substantial wealth levels, planned with some confidence that the federal exemption would shield them.

At the start of 2026, the doubled exemption framework changed. The current federal exemption, indexed for inflation, is significantly lower than the level that applied in 2025. The exact dollar amount of the current exemption is set by the rules in effect at the time of any given planning conversation, and any specific number cited today may not match the number that applies a year from now. What matters for planning is the direction: the exemption available to Northern Virginia families is materially lower than what most planning was built around through 2025.

Who Is Most Affected

Three categories of Northern Virginia households were most affected by the 2026 reset. Each one needs to take action.

Households With Combined Net Worth in the Seven to Fifteen Million Range

A married couple with a combined net worth of seven to fifteen million dollars was comfortably under the prior exemption framework with proper portability planning. Under the lower exemption in effect today, the same household may have direct federal estate tax exposure on the second death, depending on growth between now and that date. This category includes a substantial number of Northern Virginia working professional households: federal contractor employees with stock and retirement accounts, McLean and Great Falls homeowners with appreciated real estate, Fairfax and Arlington two-career professional couples with concentrated retirement balances, and Loudoun farm and equestrian families whose land has appreciated. Many of these families have plans drafted between 2018 and 2025 that assumed the higher exemption was sufficient.

Households With Combined Net Worth Above Fifteen Million

Households at this level had federal estate tax exposure under the prior framework, but had planning that used the higher exemption to lock in tax-efficient transfers. Under the lower exemption today, the same families have larger taxable estates than they did a year ago, and the trust-based architecture they put in place may need additional layers to address the increased exposure. Lifetime gifting opportunities that were planned for execution between 2024 and 2026 may have been only partially completed, and the partial completion may now leave the family with both a depleted exemption and ongoing exposure.

Households With Concentrated Illiquid Assets

Northern Virginia families whose wealth is concentrated in illiquid assets, real estate, closely held business equity, concentrated employer stock, or family farms, face an additional layer of exposure. Federal estate tax, if owed, is generally due nine months after death in cash. A family with a substantial taxable estate but limited liquid assets may be forced to sell the family business, the family farm, or the family home to raise cash for the tax payment. The prior exemption shielded many of these families from this scenario. The lower exemption today may not.

Why Acting Now Matters

Estate planning techniques that move wealth out of the taxable estate are most effective when implemented over a multi-year period and well before any incapacity, family event, or change in circumstances reduces the available options. Three reasons to act now rather than later.

First, lifetime gifting techniques benefit from time. Grantor Retained Annuity Trusts run for defined terms and produce their best results when the funding asset appreciates during the term. Spousal Lifetime Access Trusts produce their best results when the gifted assets grow inside the trust over many years. Dynasty trust funding produces compounding benefits across generations. Each of these techniques produces better outcomes the earlier it is implemented.

Second, the rules can change again. The exemption framework in effect today reflects the current statutory rules and inflation adjustments. Future legislation could raise the exemption, lower it further, or alter the underlying mechanics of estate and gift taxation. A plan calibrated to current rules now is better positioned to adapt to future rule changes than one still built on a framework that no longer applies.

Third, valuation discounts and other technical strategies require careful documentation that takes time to build. The family that engages counsel today and begins the documentation process has a stronger record than the family that scrambles after a triggering event.

What to Do This Month

If your estate plan was last updated before 2026, four steps protect your position regardless of where current legislation goes from here.

Step one: pull together your current asset inventory. Real estate at current appraised value, retirement and brokerage accounts at current balances, business interests at current valuation, life insurance at face value, and any concentrated employer stock at current market value. Most families have not assembled like this in years.

Step two: locate your existing estate planning documents. Find your will, your revocable trust, any irrevocable trusts you have established, your durable power of attorney, your advance medical directive, and your most recent beneficiary designation forms for retirement accounts and life insurance. Confirm when each was last updated.

Step three: identify your beneficiary designation gaps. Retirement accounts and life insurance pass by beneficiary designation, not by will. Outdated or inconsistent designations are among the most common HNW estate planning failures, and they undermine everything else the plan aims to accomplish.

Step four: engage counsel for a substantive review. The review can confirm that your plan still works as intended, identify recalibration opportunities, or flag immediate action items that should not wait. The conversation is more valuable when you bring the inventory and the documents than when you start from scratch.

County Specific Considerations

The 2026 reset affects each Northern Virginia county slightly differently because each county’s wealth profile differs. For Fairfax County families, federal contractor concentrated stock and McLean and Great Falls real estate appreciation drive the exposure picture. See my Fairfax County HNW estate planning lawyer guide. For Loudoun County families, the issues center on family farms, wineries, equestrian estates, and data center wealth. See my Loudoun County HNW estate planning lawyer guide. For Prince William County families, business owner equity, federal retiree benefits, and growth belt entrepreneur succession are most often discussed. See my Prince William County HNW estate planning lawyer guide. For Arlington County families, federal executive compensation, real estate in Pentagon City and Crystal City, and concentrated condo holdings are the central issues.
