The Grantor Retained Annuity Trust (GRAT): How to Transfer Millions Tax-Free Using the IRS ‘Hurdle Rate’
The Grantor Retained Annuity Trust (GRAT): How to Transfer Millions Tax-Free Using the IRS “Hurdle Rate”
CORE INSIGHTS
- The Arbitrage: A GRAT is a bet against the IRS. If your assets outperform the IRS “Hurdle Rate” (7520 Rate), the excess return passes to your heirs 100% tax-free.
- Zero Gift Tax: By setting the annuity payment equal to the asset value, you can “zero out” the gift tax. You use $0 of your lifetime exemption to move millions.
- Volatility is Good: GRATs thrive on volatility. Placing a high-growth asset (pre-IPO stock) into a GRAT just before it pops maximizes the tax-free transfer.
For ultra-high-net-worth individuals, the 40% Estate Tax is the enemy. The GRAT (Walton Strategy) neutralizes this. It freezes asset value today and ships all future upside to your children tax-free. It’s a “Heads I Win, Tails I Tie” bet.
Section 7520 Rate: IRS Hurdle (e.g., 5.0%).
Annuity: You take back Principal + 5% Interest.
Result: If asset grows 20%, the 15% spread goes to heirs. Taxable Gift Value = $0.
What-If Scenario: Pre-IPO Stock ($5M)
| Action | Value | Tax Consequence |
|---|---|---|
| Initial Gift | $5,000,000 | $0 Taxable Gift |
| IPO Growth (3x) | $15,000,000 | Trust Value Soars |
| Termination | To Heirs: ~$10M | $0 Estate Tax |

Strategic Action Steps
GRATs work best when the 7520 Rate is low. A lower hurdle makes it easier to beat the IRS assumption.
Do not use bonds. Use assets with explosive potential (Tech Stocks, Private Equity). You want to crush the hurdle rate.
Use short-term (2-year) GRATs. If one fails (asset drops), it returns to you. If one succeeds, it transfers wealth. Rolling them creates multiple shots on goal.
The Bottom Line: Who Should Choose What?
- Choose GRAT: UHNW ($20M+) with volatile assets who want to transfer wealth without using exemption.
- Choose IDGT: If you want to transfer assets permanently and lock in GST tax benefits (GRATs are weak on GST).
Frequently Asked Questions
What is a ‘Zeroed-Out’ GRAT?
It is structured so the present value of annuity payments equals the contribution. The IRS calculates the gift value as $0, so no tax is owed.
What is the ‘Hurdle Rate’?
The IRS Section 7520 Rate. If assets grow faster than this rate, the strategy succeeds. If slower, assets return to you with no penalty.
Why use ‘Rolling GRATs’?
Short-term GRATs isolate volatile ‘up’ years to capture gains, while ‘down’ years just fail harmlessly. Long-term GRATs average out returns, which is bad.
