Estate tax planning in 2026 is undergoing a major reset. With the passage of the One Big Beautiful Bill Act (OBBBA), the federal lifetime estate and gift tax exemption has increased to $15 million per individual and $30 million per married couple. This historic shift presents a rare opportunity to preserve generational wealth—but only for those who act strategically and early.
What Might Change for Estate Tax Planning in 2026?
The OBBBA, signed into law in July 2025, eliminated the sunset provisions of the Tax Cuts and Jobs Act (TCJA) and established permanent estate tax rules starting in 2026. Key updates include:
- Lifetime Estate & Gift Tax Exemption: Raised to $15 million per person, indexed for inflation starting in 2027.
- Annual Gift Tax Exclusion: Remains at $19,000 per recipient ($38,000 for married couples using gift splitting).
- Qualified Charitable Distribution (QCD) Limit: Increased to $115,000.
- State-Level Considerations: States like Massachusetts still impose separate estate taxes, making federal planning even more critical.
Why Planning Now Matters
Estate planning is no longer just for the ultra-wealthy. Mid-affluent families—those with estates between $7 million and $20 million—are increasingly exposed to estate tax risk due to asset growth and inflation. With the federal estate tax rate at 40%, failing to lock in today’s exemption could result in millions in unnecessary taxes.
Example: A couple with a $10 million estate today could see their assets double over the next decade. Without proactive planning, they may exceed future exemption thresholds and face a tax liability of up to $4 million.
Top Estate Tax Planning Strategies for 2026
To take full advantage of the new exemption and avoid future claw-backs, consider these proven strategies:
1. Use Lifetime Gifting Strategically
- Make tax-free gifts up to $19,000 per recipient annually.
- Use gift splitting to double the exclusion for married couples.
- Accelerate contributions to 529 plans using the five-year election rule.
2. Establish Irrevocable Trusts
- Set up Spousal Lifetime Access Trusts (SLATs) to preserve access while removing assets from your taxable estate.
- Consider Grantor Retained Annuity Trusts (GRATs) or Intentionally Defective Grantor Trusts (IDGTs) for high-growth assets.
3. Review and Update Existing Trusts
- Ensure formulas and distribution clauses reflect the new exemption.
- Coordinate spousal plans to fully utilize both exemptions.
4. Plan for State Estate Taxes
- States like Massachusetts have a $2 million exemption per person.
- Use federal gifting strategies to reduce state-level estate tax exposure.
5. Lock in Today’s Exemption
- The IRS has confirmed that gifts made under the current exemption won’t be clawed back—even if future laws reduce the threshold.
- This creates a “use it or lose it” scenario for families near or above the exemption limit.
Timeline: What to Do Before Year-End
By December 31, 2025:
- Finalize large gifts to lock in the $15M exemption.
- Review trust documents and update outdated provisions.
- Coordinate with your estate planning attorney and CPA.
In 2026:
- Continue annual gifting.
- Monitor legislative changes and inflation adjustments.
- Reassess your estate’s growth trajectory and adjust strategies accordingly.
