What is a generation skipping transfer or GST exemption

Emily was meticulous. She funded a trust for her grandchildren, believing she’d secured their financial future. What she didn’t anticipate was the rapid increase in property values and the complexities of the generation-skipping transfer tax. Now, her family faces a potential 40% tax bill on distributions simply because the trust exceeded the exemption amount, costing them a significant portion of the intended inheritance.

As an estate planning attorney and CPA with over 35 years of experience, I frequently encounter clients like Emily who are unaware of the intricacies surrounding the generation-skipping transfer (GST) tax. It’s a hidden landmine that can decimate even well-funded trusts if not proactively addressed. The good news is, with careful planning, these taxes can be significantly mitigated or even avoided entirely.

What exactly is a generation-skipping transfer?

Simply put, a generation-skipping transfer occurs when assets are passed from you (the grantor) to someone two or more generations younger than you – typically grandchildren, great-grandchildren, or even more distant descendants. This bypasses the intervening generation (your children) and can trigger a substantial tax liability. The IRS views this as a potentially significant tax saving maneuver and therefore subjects it to a separate tax regime.

How does the GST tax work?

The GST tax is a 40% tax imposed on transfers exceeding a per-person exemption amount. The exemption exists to allow for legitimate family wealth transfer without excessive tax burden. Currently, the Federal GST Tax Exemption is a substantial amount, but it’s subject to change with legislation. It’s critical to understand that this exemption is portable – meaning it can be applied over your lifetime, or it can be allocated to your trust during your lifetime to “lock in” the exemption amount.

What is the OBBBA and how does it impact my GST planning?

Effective Jan 1, 2026, the OBBBA set the Federal GST Tax Exemption to $15 million per person; properly allocating this exemption is the only way to shield future generations from an immediate 40% tax on distributions. Prior to the OBBBA, the exemption amount was significantly lower and subject to inflation adjustments. The increased exemption offers greater flexibility, but proper allocation requires diligent recordkeeping and ongoing review. Failure to make a timely and valid allocation can result in the loss of valuable exemption.

How can a CPA help with GST planning?

This is where my dual role as an attorney and CPA becomes invaluable. The GST tax isn’t just a legal issue; it’s fundamentally a tax issue. Understanding the step-up in basis, capital gains implications, and proper valuation of assets are crucial to minimizing tax liability. For example, accurately valuing illiquid assets like real estate or closely held business interests is paramount. We can structure the trust to take advantage of valuation discounts and optimize the use of the exemption, maximizing the benefit to your beneficiaries. Furthermore, a CPA can advise on the potential impact of future tax law changes.

Why is strategic trust drafting essential?

The trust document itself is the key to successful GST planning. It must clearly define the beneficiaries, the distribution terms, and, most importantly, include specific language allocating the GST exemption. Without this language, the trust will likely be subject to the 40% tax. Moreover, trust duration also plays a critical role. Unlike ‘forever’ trust states, California follows the Uniform Statutory Rule Against Perpetuities (USRAP), generally limiting a Dynasty Trust’s existence to 90 years unless specific ‘savings clauses’ or jurisdiction-shifting provisions are drafted.

What happens if I don’t properly allocate the GST exemption?

If you fail to allocate the exemption during your lifetime, the full 40% tax will be due on any distributions exceeding the then-current exemption amount. This can significantly reduce the value of the trust and defeat the purpose of your planning. It’s a costly mistake that can be easily avoided with proactive estate planning. We can review your existing trust to identify any potential issues and ensure that it’s properly structured to maximize tax benefits for your beneficiaries.

What determines whether a California trust settlement remains private or erupts into public litigation?

The advantage of a California trust is control and continuity, but this relies entirely on accurate funding and disciplined administration. Without clear asset titles and strict adherence to fiduciary standards, a private trust can quickly become a subject of public litigation over mismanagement, capacity, or undue influence.

To ensure the plan actually works, you must move assets correctly using trust funding procedures, and ensure all players understand their roles by identifying the trustees and beneficiaries to prevent confusion when authority transfers.

Ultimately, the success of a trust depends on the details—proper funding, clear terms, and a trustee willing to follow the rules. By anticipating friction points and documenting every step of the administration, fiduciaries can protect the estate and themselves from liability.

Verified Authority on California Dynasty Trust Administration

• Trust Duration Limits (USRAP): California Probate Code § 21205 (90-Year Rule)
  The governing statute for the Uniform Statutory Rule Against Perpetuities. Unlike states that allow “forever” trusts, California generally limits a Dynasty Trust’s validity to 90 years, requiring careful drafting to avoid premature termination.
• GST Tax Exemption (OBBBA): IRS Generation-Skipping Transfer Tax
  Detailed guidelines reflecting the OBBBA update. Effective January 1, 2026, the GST Tax Exemption is permanently set at $15 million per person, allowing for massive tax-free wealth transfer to grandchildren if allocated correctly.
• Property Tax Reassessment (Prop 19): California State Board of Equalization (Prop 19)
  Crucial for Dynasty Trusts holding real estate. Prop 19 severely limits the ability to pass low property tax bases to grandchildren, often triggering reassessment to current market value upon the child’s death.
• Primary Residence Succession (AB 2016): California Probate Code § 13151 (Petition for Succession)
  If a residence intended for the trust was accidentally left out, this statute (effective April 1, 2025) allows a “Petition for Succession” for homes valued up to $750,000, avoiding a full probate proceeding.
• Digital Asset Access (RUFADAA): California Probate Code § 870 (RUFADAA)
  The authoritative resource on digital assets. Without specific RUFADAA language in the Dynasty Trust, multi-generational access to crypto wallets and digital archives can be legally blocked by service providers.
• Business & LLC Compliance (FinCEN): FinCEN – Beneficial Ownership Information (BOI)
  While domestic U.S. LLCs in the trust are now exempt (as of March 2025), trustees managing foreign-registered entities must still comply with strict 30-day reporting windows to avoid federal penalties.
