U.S. Estate & Gift Tax Planning Before 2026: Protecting Wealth Under the Sunset Rules

U.S. Estate & Gift Tax Planning Before 2026: Protecting Wealth Under the Sunset Rules

For high-net-worth Americans, the window for tax-efficient wealth transfer is closing fast. The Tax Cuts and Jobs Act (TCJA) temporarily doubled the estate and gift tax exemption to USD 13.99 million per person in 2025, but that benefit will end after December 31, 2025, unless Congress acts. Starting January 1, 2026, the exemption is projected to drop to roughly USD 6.8 million, exposing many families to estate tax for the first time. Strategic planning, through lifetime gifting, trust structuring, and charitable or spousal transfers, can preserve millions in tax savings. Contact Bordera Tax and Immigration Law to review your estate plan and secure your exemption before the 2026 sunset takes effect. 

The 2026 Estate Tax Countdown

For years, affluent Americans have benefited from historically high estate and gift tax exemptions introduced by the 2017 Tax Cuts and Jobs Act (TCJA). As of October 2025, the federal exclusion sits at USD 13.99 million per individual (USD 27.98 million for married couples). 

Unless extended by Congress or modified through new legislation such as the proposed Big Beautiful Bill Act of 2025, the exemption will revert to roughly USD 6.8 million per person (indexed for inflation) on January 1, 2026. 

The top federal estate tax rate remains 40%, and several states—including New York, Massachusetts, and Oregon—impose additional estate or inheritance taxes. For many business owners, real-estate investors, and professionals, this reversion could trigger significant tax liabilities on assets that were previously exempt. 

Now is the time to evaluate gifting strategies, update trusts, and coordinate with your advisors before the exemption cuts in half. 

Why the 2026 Sunset Matters


The estate and gift tax exemption shields a lifetime total of USD 13.99 million from federal transfer tax. When it drops to around USD 6.8 million, estates exceeding that value will owe up to 40% tax on the excess. The reduction also affects: 

  • Lifetime gifts made after 2025 
  • Generation-skipping transfers (GST) 
  • Family business succession and closely held entity valuations 

The IRS has confirmed under T.D. 9884 that gifts made between 2018 and 2025 under the higher exemption will not be clawed back once the limit decreases. This makes 2025 a unique opportunity for proactive transfers.

Planning Opportunities Before 2026


1. Use Your Lifetime Exemption Now 

Make substantial gifts to family members or irrevocable trusts before year-end 2025. These can include interests in family businesses, investment portfolios, or real estate. 

2. Establish or Update Trusts

Irrevocable Life Insurance Trusts (ILITs), Spousal Lifetime Access Trusts (SLATs), and Dynasty Trusts can help move assets out of your taxable estate while retaining control or benefit for your family. 

3. Leverage Valuation Discounts 

Transfers of minority interests in family partnerships or LLCs can qualify for valuation discounts under current rules—reducing the taxable gift amount. 

4. Integrate Charitable Giving 

Charitable Remainder Trusts (CRTs) and Donor-Advised Funds allow high-income individuals to meet philanthropic goals while reducing estate exposure. 

5. Review State-Level Exposure 

States like New York, Massachusetts, and Oregon impose estate taxes with lower exemptions. Relocation or state-specific planning can significantly reduce exposure. 

Documentation and Compliance Essentials 

  • Form 709 – Gift Tax Return: Report all taxable gifts and apply your lifetime exemption. 
  • Form 706 – Estate Tax Return: Due within nine months of death; extension available via Form 4768. 
  • Portability: Surviving spouses can transfer unused exemption with a timely filed return. 
  • Appraisals: Professional valuations are essential to substantiate discounts and defend IRS audits. 

Each strategy must align with your broader financial plan and meet IRS documentation standards.
