If you hold an asset you expect to appreciate sharply, there’s a well-established technique designed to hand the growth to your heirs at little or no transfer-tax cost.
The scenario. Patricia, 68, held a concentrated position in a stock she believed would appreciate significantly, plus other assets pushing her estate to $35 million. She wanted to pass the upside to her children but didn’t want to use up her exemption or pay gift tax. Without planning, all of the stock’s future appreciation would simply grow inside her taxable estate, eventually taxed at 40%. She’d never heard of a tool designed for exactly this situation.
The problems.
- Concentrated, appreciating assets were growing inside a taxable estate.
- No mechanism existed to transfer appreciation without large gift-tax cost.
- All future growth was fully exposed to the 40% estate tax.
The planning solution.
A Grantor Retained Annuity Trust (GRAT) is an irrevocable trust built to transfer appreciation rather than principal. Here’s the mechanism:
You transfer an appreciating asset into the GRAT and retain the right to receive an annuity — a fixed payment back to yourself — for a set term of years. At the end of the term, whatever remains in the trust passes to your beneficiaries.
The tax magic is in how the gift is valued. The IRS assumes the asset will grow only at the §7520 “hurdle rate” (a rate the IRS publishes monthly). When you set the annuity so that the present value of your retained payments equals what you put in — a “zeroed-out” GRAT — the taxable gift is near zero. Then, if the asset actually outperforms that hurdle rate, all of the excess appreciation passes to your heirs gift-tax-free, using essentially none of your lifetime exemption.
The principal risk is mortality: if you die during the GRAT term, the assets are pulled back into your taxable estate, and the strategy simply fails (you’re no worse off than not having done it, but you lose the benefit). The standard way to manage this is to use short-term, “rolling” GRATs — a series of two- or three-year GRATs — which reduces the chance of dying mid-term and lets you capture volatility year by year (locking in winners and re-trying with losers).
GRATs work best for assets with high expected appreciation or volatility — pre-IPO stock, a concentrated equity position, or interests in a growing business — especially when the §7520 rate is relatively low. They’re a favorite tool for moving the growth of an asset to the next generation while barely touching your exemption.
Key takeaways.
- A GRAT passes appreciation above the IRS §7520 hurdle rate to heirs gift-tax-free.
- “Zeroing out” the GRAT makes the taxable gift near zero.
- Use short-term rolling GRATs to manage the mortality risk.
