Two California families. Same starting wealth. Same investment returns. Same time horizon.
Sixty years later:
• One family’s descendants control $661 million
• The other controls $396 million — and continues losing ground
The difference is not investment strategy.
It is not timing.
It is not luck.
It is one federal tax — and one exemption most families never use correctly.
The tax is the generation-skipping transfer tax (GST).
The exemption is $15 million per person under current law.
This article explains what the GST tax actually is, how the exemption works, where mistakes happen in practice, and when CPAs should flag clients for planning.
⸻
What the GST Tax Actually Is
The estate tax takes up to 40% at each generational transfer.
To prevent families from skipping that tax by transferring directly to grandchildren, Congress created a second layer:
The GST tax.
It applies when wealth moves to a “skip person” under IRC §2613—typically grandchildren or more remote descendants.
The rate: 40%.
Without planning, the same wealth can be:
• Taxed at 40% when passing from parent to child
• Taxed again at 40% when it reaches grandchildren
This is not a technical edge case.
It is a structural tax applied to long-term family wealth.
⸻
How the GST Tax Gets Triggered
There are three trigger points CPAs should recognize:
1. Direct Skip
A transfer directly to a grandchild or skip person.
2. Taxable Termination
When a trust shifts from benefiting a child to benefiting only grandchildren.
3. Taxable Distribution
When a non-exempt trust distributes to a skip person.
All three depend on one number:
The inclusion ratio.
⸻
The Inclusion Ratio — The Number That Determines Everything
Every trust that can benefit grandchildren has an inclusion ratio between 0 and 1.
• 0 = fully GST exempt (no tax)
• 1 = fully exposed (40% tax applies)
• Between = partial exposure
Example:
• $10M trust, inclusion ratio = 0 → $0 GST tax
• $10M trust, inclusion ratio = 1 → $4M tax
• $10M trust, inclusion ratio = 0.5 → $2M exposed → $800K tax
Most poorly structured trusts land in the fractional range.
That’s where silent, compounding tax erosion occurs over decades.
The objective is simple:
Zero inclusion ratio.
⸻
How the Exemption Works (And Why Timing Matters)
The GST exemption is $15M per person ($30M married).
It is allocated:
• On Form 709 (lifetime)
• Or Form 706 (at death)
Once allocated correctly:
• The trust achieves a zero inclusion ratio
• All future appreciation is sheltered from GST tax
Key principle:
The exemption applies to the value at the time of transfer—not future growth.
A $15M transfer today can shield $150M+ over time.
⸻
Why the Current Window Matters
The exemption is historically high.
But it is not guaranteed.
The key protection is anti-clawback under Treasury Reg. §20.2010-1(c):
• If exemption is used today, it is locked in
• Future reductions do not retroactively apply
That means:
• A properly funded trust today keeps its protection
• Even if the exemption drops later
Every year of delay:
• Moves appreciation into the taxable estate
• Increases future exposure
• Cannot be reversed
⸻
Where CPAs Miss This (And Why It Matters)
Most GST failures are not aggressive planning mistakes.
They are assumption errors:
• Assuming automatic allocation applies
• Assuming the trust qualifies
• Assuming someone else handled it
• Assuming the inclusion ratio is zero without confirming
By the time the mistake is discovered:
• The trust is already funded
• The allocation window may have passed
• The exposure is locked in
This is not a correction issue.
It’s a structural failure.
⸻
Five Drafting Mistakes That Cost Families Millions
1. No intentional GST allocation
→ Inclusion ratio defaults to 1
2. Outright distribution to grandchildren
→ Triggers taxable termination
3. General powers of appointment
→ Pulls assets into taxable estate (IRC §2041)
4. Trust fails GST trust definition
→ Automatic allocation never applies
5. Outdated trust design (pre-2020 exemptions)
→ Inefficient allocation relative to current law
These errors are common.
And they are expensive.
A dynasty trust with the right intentions and the wrong drafting can cost a family enormous sums in avoidable GST tax.
⸻
Two Families. One Decision. $265M Difference.
Both families start with $20M. Most families never have had this conversation.
Family A (standard planning):
• Assets pass to children
• Grow to ~$115M
• ~40% estate tax → ~$69M to grandchildren
• Grow to ~$396M
• Tax cycle repeats
Family B (GST-exempt dynasty trust):
• $20M funded into trust
• Inclusion ratio = 0
• Grow to ~$115M → no tax
• Grow to ~$661M → no generational tax
Difference: $265M
Same investments.
Same time horizon.
Different structure.
⸻
Where This Shows Up in Your Practice
CPAs should flag clients when:
• Net worth exceeds $10M–$15M
• Significant appreciation is expected
• Trusts benefit multiple generations
• No clear GST allocation is documented
• Estate planning has not been reviewed recently
These are not edge cases.
These are common profiles.
⸻
The California Real Estate Tradeoff
There is one real tension:
Step-up in basis vs. estate tax exposure
• Holding property → eliminates capital gains at death
• But includes full value in taxable estate
• Transferring early → removes future appreciation from estate
• But loses step-up in basis
At scale:
• Estate tax (~40%) often exceeds capital gains (~20–37%)
For high-growth assets:
Early transfer frequently wins.
For lower-growth assets:
Holding for step-up may be preferable.
This is not theoretical.
It is a property-by-property analysis.

How the Dynasty Bridge Trust™ Integrates GST Planning
For families needing both:
• Creditor protection (lifetime)
• Tax efficiency (multi-generational)
The Dynasty Bridge Trust™ combines both in one structure.
• Bridge Trust® → enforcement barrier during life
• Dynasty structure → GST-exempt compounding after death
Key point for CPAs:
• Grantor trust status (income tax)
• GST exemption (transfer tax)
These operate independently.
The structure can be:
• Tax-transparent during life
• Tax-shielded across generations
⸻
When to Raise the Conversation
This is not a strategy to implement later.
It must be structured before the assets grow.
CPAs do not need to design the solution.
They need to recognize when the issue exists.
If a client meets the profile and:
• No GST allocation is confirmed
• No dynasty structure exists
• No long-term transfer strategy is in place
Then the planning is incomplete.
⸻
The Question That Actually Matters
Most families at this level have:
• A RLT trust
• A CPA
• A financial advisor
What they don’t have is a plan that answers this:
What happens to this wealth across two + generations?
Because that’s where the real cost is.
Not in year one.
But over time.
The numbers are not hypothetical.
They are arithmetic.
And the only variable is whether the structure is in place before the growth occurs.
Structure before stress.
