Key Changes Under OBBBA

  • Permanent Exemption Increase: Starting January 1, 2026, the unified federal estate, gift, and GST tax exemption rises to $15 million per individual (indexed for inflation), or $30 million for married couples.
  • No More Sunset Uncertainty: The previous exemption, set under the Tax Cuts and Jobs Act (TCJA), was scheduled to drop sharply at the end of 2025. OBBBA eliminates this “sunset,” providing certainty and removing the pressure to make large gifts before year-end.
  • Inflation Indexing: The new $15 million exemption will be indexed for inflation going forward, increasing its value over time.

What This Means for Estate Planning

1. More Time for Strategic Planning

  • The urgency to complete large gifts before December 31, 2025, is gone. Families can now plan gifts and transfers thoughtfully, rather than rushing to meet an artificial deadline.
  • This stability allows for better long-term strategies, such as gradual gifting, trust creation, and business succession planning.

2. Review and Update Estate Plans

  • With the exemption amount permanently higher, many existing estate plans (especially those drafted under lower exemption assumptions) may be outdated.
  • Review trust structures, beneficiary designations, and gifting strategies to ensure they align with the new law and your family’s goals.

3. Expanded Opportunities for Lifetime Gifting

  • The increased exemption enables larger lifetime gifts without triggering federal gift tax. This can be used to transfer appreciating assets out of your estate, reducing future estate tax exposure.
  • Annual exclusion gifts (currently $19,000 per recipient in 2025) remain a separate, additional planning tool.

4. Consider the Generation-Skipping Transfer (GST) Tax

  • The GST exemption also rises to $15 million, allowing for more tax-efficient transfers to grandchildren and future generations.

5. Stay Proactive

  • While OBBBA provides stability, tax laws can change with future political shifts. Take advantage of the current environment, but remain flexible and consult with your advisors regularly
