Key Takeaways
A grantor retained annuity trust, or GRAT, lets you transfer an asset’s future growth to your heirs while using little of your lifetime gift-tax exemption. Success depends on the asset’s annual growth rate exceeding a rate the IRS sets monthly (currently 5.2% as of this writing in August 2026, and updated here on a monthly basis). If a stock or business grows faster than 5.2% per year over the GRAT’s term, that extra growth can pass to beneficiaries with little added gift tax.
- GRATs are generally most compelling for assets with strong future appreciation potential, particularly when that growth could occur over a relatively short period.
- Shorter-term rolling GRATs can provide flexibility by creating repeated opportunities to transfer appreciation rather than relying on one long-term investment outcome.
- A GRAT funded simply because an asset has already appreciated significantly can be a weaker candidate than it first appears. A low cost basis tells us what an investment did in the past, whereas a GRAT’s success depends on what it does next.
Successful investing can create a welcome planning challenge: as assets appreciate, a family’s potential estate-tax exposure can grow with them.
A grantor retained annuity trust, or GRAT, provides a way to transfer some of that future appreciation to the next generation.
The concept is relatively straightforward. You transfer an asset to an irrevocable trust and retain the right to receive a series of annuity payments for a defined period. At the end of the term, assets remaining in the GRAT pass to your beneficiaries.
Under Internal Revenue Code §2702, special valuation rules apply to certain transfers in trust to family members when the person making the transfer retains an interest. GRATs can be structured so the grantor retains a qualifying annuity interest.
Because the grantor keeps the right to those annuity payments, their actuarial value reduces the value of the gift to the remainder beneficiaries.
That creates the foundation for what is commonly called a “zeroed-out” GRAT. With careful structuring, the present value of the retained annuity can approximately equal the value contributed to the GRAT. The resulting taxable gift can therefore be very small.
The planning opportunity comes from what happens next.
How A Grantor Retained Annuity Trust Transfers Future Appreciation
Every GRAT has a hurdle rate determined under §7520. The IRS publishes this rate monthly. As of this writing in August 2026, the rate is 5.2%.
For GRAT planning, you can think of that rate as the performance hurdle. Investment growth above the assumed rate creates value for the beneficiaries.
To better illustrate how this works, let’s look at a hypothetical example:
- Initial asset transfer: $5,000,000
- Trust term: two years
- IRS hurdle rate: 5.2%
- Beneficiaries: children, or other heirs
- Annuity requirement: level annual payments sized to return the principal plus the assumed 5.2% growth, zeroing out the taxable gift. That works out to approximately $2.70 million per year for two years, or about $5.39 million total.
Now consider how that hypothetical setup could play out over the two-year term.
- Growth: the IRS assumption is 5.2% annual growth. Now suppose the asset actually appreciates 15%
- Annuity returns to the grantor: the trust pays the grantor the required $2.70 million annuity each year, regardless of how the asset performs.
- Surplus to beneficiaries: because actual growth outpaces the 5.2% hurdle, approximately $815,000 remains in the trust at the end of Year 2 and passes to the beneficiaries with negligible additional gift or estate tax.
- If the asset underperforms: if growth comes in at or below the 5.2% hurdle, the annuity payments simply return the principal and assumed growth to the grantor. Little or nothing remains for beneficiaries, but the family has not used up gift-tax exemption in the process.
The actual outcome will depend on trust terms, valuation, payment timing, investment returns, and other assumptions. The illustration nevertheless demonstrates the central idea: the GRAT is designed to transfer investment performance above the IRS assumption.
The Best GRAT Assets Have Future Upside, Not Just Past Appreciation
Asset selection matters more here than how much the asset has already appreciated. What matters is what it can reasonably be expected to do from here.
A stock position with an extremely low cost basis may initially look like an obvious GRAT candidate. Yet its low basis simply tells us that it performed well in the past. A GRAT needs strong performance in the future.
The stronger candidates are assets with a credible opportunity for substantial future appreciation. Depending on the circumstances, that could include a rapidly growing closely held business, certain private investments, a pre-liquidity-event business interest, or a public stock with significant appreciation potential.
Other characteristics matter too. The asset should fit the GRAT’s time horizon, provide a workable way to satisfy the annuity payments, and, when privately held, have a supportable valuation.
For business owners, GRAT planning deserves consideration well before a potential transaction becomes imminent. As a sale progresses and the value of the business becomes more certain, valuation and tax considerations can become more complicated. Earlier planning generally gives the family’s legal, tax, and financial advisors more options to evaluate.
Our broader approach to tax-efficient investing follows the same principle: investment, gifting, and tax decisions should be evaluated together rather than in isolation.
The Value of Flexibility In GRAT Planning
Preserving the ability to make repeated planning decisions, rather than relying on one long-term forecast, can be valuable when circumstances support it. This is one reason shorter-term, rolling GRATs can be attractive.
A family might establish a shorter GRAT, receive the required annuity payments, and subsequently use returned assets to fund another GRAT. Successive GRATs create additional opportunities to capture periods of strong appreciation while reducing the length of time over which any single GRAT is exposed to investment uncertainty and mortality risk.
This is not an automatic recommendation for every family. Asset characteristics, transaction costs, administration, health, estate size, and the family’s objectives all matter. The broader principle is more important: the trust term should serve the planning opportunity, rather than simply locking an asset away for as long as possible.
How GRAT Income Taxes Are Typically Handled
GRATs are commonly structured as grantor trust for federal income-tax purposes during the annuity term. As a result, the grantor generally reports the trust’s taxable income, dividends, interest, and capital gains on the grantor’s individual income-tax return.
Although this may create an additional tax obligation for the grantor, it can also enhance the planning strategy because trust assets are generally able to remain invested rather than being reduced by income-tax payments made directly from the trust. As with other aspects of GRAT planning, sufficient personal liquidity is important to ensure the grantor can comfortably satisfy any resulting tax liability.
GRATs Have Important Tradeoffs
A GRAT’s mechanics are straightforward, but several factors determine whether it actually delivers the intended benefit:
- Mortality risk. If the grantor dies during the GRAT term, some or all of the GRAT property may be included in the grantor’s taxable estate. Longer GRAT terms therefore introduce an additional planning consideration.
- The GRAT must make its required annuity payments. An asset whose cash-flow profile makes those payments difficult to satisfy, or whose valuation could create unnecessary uncertainty, deserves particular scrutiny before funding a GRAT.
- Valuation and structure. An investment opportunity may look attractive, but valuation, distributions, ownership restrictions, and how the GRAT will satisfy its annuity obligation still need consideration.
A technically valid GRAT can still be a poor financial-planning decision if the underlying asset creates excessive liquidity or administrative pressure.
Estate Tax Savings Should Be Weighed Against Income Taxes
This is an area where integrated financial planning becomes especially valuable.
Assets successfully transferred through a GRAT generally carry their existing tax basis. By comparison, property included in a decedent’s estate may qualify for a basis adjustment at death under applicable tax law. That can create competing tax objectives.
Removing substantial future appreciation from an estate can reduce potential estate-tax exposure. Retaining a highly appreciated asset until death, however, may produce a valuable income-tax basis adjustment.
We do not want to minimize estate tax in isolation. The goal is to preserve more family wealth after all relevant taxes.
For a family with significant embedded capital gains, we therefore want to model both sides of the decision. Our discussion of upstream gifting addresses a related planning challenge: sometimes an asset’s future income-tax treatment can materially change the economics of a wealth-transfer decision.
When Does A Grantor Retained Annuity Trust Make Sense?
For successful families, the most useful GRAT questions are practical ones.
- Which asset has the strongest future appreciation potential?
- How likely is that appreciation to exceed the current §7520 hurdle?
- Does the family have sufficient liquidity?
- How long should the GRAT run?
- What income-tax consequences accompany the estate-tax benefits?
- And what happens if the investment performs differently than expected?
Working with a single, coordinated advisor can help a family answer these questions effectively.
