A grantor retained annuity trust (GRAT) can be a powerful estate planning tool and has been widely used by high-net-worth individuals.
If you have appreciated assets and want to transfer wealth to your beneficiaries while minimizing gift tax exposure, understanding how a GRAT works could be a valuable approach in your estate planning.
This article explains what a GRAT is, walks through a real-world example of a grantor-retained annuity trust, and outlines the key risks you should understand before moving forward.

What Is a GRAT?
A grantor-retained annuity trust is an irrevocable trust into which a grantor — the person creating the trust — transfers assets and then receives fixed annuity payments for a set term. At the end of the term, any assets still in the GRAT will pass to the remainder beneficiary, typically children or other heirs, often with little or no gift tax.
The GRAT trust structure is authorized under IRC Section 2702, which governs the valuation of transfers to a trust when the grantor retains an interest.
The IRS publishes a monthly discount rate—known as the Section 7520 rate, or simply the 7520 rate—that serves as the hurdle rate a GRAT must exceed for wealth transfer to occur.
This rate is essentially the IRS’s assumed rate of return. If the assets inside the GRAT outperform this hurdle rate, the excess appreciation passes to the remainder beneficiaries free of additional gift tax.
A GRAT is irrevocable, meaning the grantor generally cannot revoke the trust or freely withdraw its assets. However, the grantor retains the right to receive the scheduled annuity payments during the trust term.
How Does a GRAT Work?
Understanding how a GRAT works requires examining each stage of the trust’s life cycle.
Step 1: Establishing the Trust
The grantor works with an estate planning attorney to draft and fund the GRAT. This is not the role of a financial advisor—it requires legal counsel experienced in estate planning and irrevocable trusts. Assets such as stock, real estate, or an interest in a private company are transferred to the trust.
Step 2: Calculating the Gift
When assets are placed in a GRAT, the IRS treats the transfer as a taxable gift — but only to the extent of the “remainder interest,” which is the present value of what the beneficiaries are expected to receive.
Using the 7520 rate as the discount rate, the IRS calculates how much of the initial contribution is expected to be returned to the grantor through annuity payments. The remainder is the taxable gift.
In what is known as a zeroed-out GRAT, the annuity payments are structured so that the present value of all payments to the grantor equals the full value of the transferred assets. As a result, the taxable gift is reduced to zero or near zero.
This is a common strategy and is legal under current tax law, largely because of a landmark court case involving members of the Walton family. Consequently, zeroed-out GRATs are often called Walton GRATs.
Step 3: Annuity Payments
During the GRAT term, the grantor receives annuity payments from the trust acount determined by the trust documents. The payments may remain level or increase according to a schedule established when the trust is created.
Step 4: End of the Term — Remainder to Beneficiaries
At the end of the trust term, any assets remaining in the trust—everything that grew beyond what was needed to fund the annuity payments—pass to the remainder beneficiary or beneficiaries. This transfer is not subject to additional gift tax because the gift was already valued (often at zero) when the trust was created.
The wealth that passes to the beneficiaries is effectively the trust’s investment appreciation above the 7520 hurdle rate. That excess—which could be substantial for a fast-growing stock or private company interest—leaves the grantor’s taxable estate with little or no gift or estate tax cost.
A Grantor Retained Annuity Trust Example
Suppose a grantor transfers $2 million of appreciated stock into a two-year GRAT when the Section 7520 rate is 5%.
To create a zeroed-out GRAT, the trust is structured to make two equal annual annuity payments of approximately $1,075,610 to the grantor. Although those payments total about $2.15 million, their present value, discounted at the 5% Section 7520 rate, equals the $2 million initially contributed.
As a result, the value of the taxable gift to the remainder beneficiaries is approximately zero when the GRAT is created.
Assume the stock then grows by 10% annually. At the end of the first year, the $2 million investment had grown to $2.2 million. After the first annuity payment of approximately $1,075,610, about $1,124,390 remains in the GRAT.
During the second year, that remaining balance grows to approximately $1,236,829. After the second annuity payment is made, approximately $161,220 remains in the trust. That amount passes to the remainder beneficiaries without an additional taxable gift.
The beneficiaries are not receiving all of the stock’s appreciation. Economically, the strategy transfers the investment return earned in excess of the IRS-assumed rate.
This is the central appeal of GRAT planning: transferring future appreciation above the Section 7520 hurdle rate to beneficiaries with little or no gift-tax cost.
Key Concepts in GRAT Estate Planning
Several structural decisions shape a GRAT’s effectiveness. The interest rate environment, the length of the trust term, and the types of assets placed in the trust all influence whether, and how much, wealth ultimately passes to beneficiaries. Understanding these variables helps grantors and their advisors design an effective GRAT strategy tailored to their circumstances.
The 7520 Rate and Hurdle Rate
The Section 7520 rate, published monthly by the IRS, is the benchmark a GRAT must beat. It serves as both the discount rate for calculating the gift value and the effective hurdle rate for the strategy.
In a low-interest-rate environment, this hurdle is easier to clear, making GRATs particularly attractive. In a high-interest-rate environment, the trust’s assets must grow faster to generate meaningful transfers, thereby reducing the strategy’s effectiveness.
Short-Term GRATs and GRAT Ladders
Many advisors and attorneys recommend short-term GRATs (two-year terms are common) because they shorten the time the grantor must survive for the strategy to succeed.
Some practitioners advocate a rolling GRAT strategy, sometimes called a GRAT ladder, in which the grantor establishes a new GRAT each year using annuity payments from previous GRATs. This creates a series of overlapping trusts that continuously capture fresh appreciation.
Asset Selection
Not all assets are equally well-suited for a GRAT. The strategy works best with assets expected to appreciate significantly—such as concentrated stock positions, interests in a private company, pre-IPO shares, or real estate in growth markets.
Placing volatile assets into a GRAT can also be advantageous because if the assets decline in value, the grantor can simply “unwind” the underperforming GRAT with no harm done (the gift value was already zero) and start fresh with a new trust at a lower asset basis.
Who Uses GRATs?
GRATs are primarily used by high-net-worth individuals and families with significant assets expected to appreciate and are trying to reduce the size of their taxable estate over time.
GRATs have attracted considerable attention over the years because some of the wealthiest families and executives in America have used them to transfer significant amounts of assets to heirs with minimal gift or estate taxes. GRATs are a sophisticated strategy that requires careful planning to tax-efficiently transfer wealth to heirs.
Risks of a GRAT
While the GRAT trust structure offers compelling benefits, it also carries meaningful risks that every grantor must understand.
Risk 1: Death During the Term
This is the most significant risk in GRAT estate planning. If the grantor dies before the GRAT term ends, some or potentially all of the GRAT assets may be included in the grantor’s gross estate because the grantor still held the right to receive the annuity payments. This may reduce or eliminate the intended estate-tax benefit.
This “grantor dies during term” risk is why short-term GRATs are often preferred to long-term structures. A two-year GRAT carries significantly less mortality risk than a ten-year GRAT.
For older grantors or those with health concerns, the trust term must be carefully weighed against life expectancy. For older grantors or those with health concerns, the GRAT term should be carefully weighed against the likelihood that the grantor will survive the entire term.
In some cases, a separate irrevocable life insurance trust may be used as a hedge against this risk. If the grantor dies during the GRAT term, the insurance trust can replace the wealth the GRAT was intended to transfer or provide liquidity for estate taxes that may now be due because some (or all) of the GRAT assets will be pulled back into the estate.
The insurance does not preserve the GRAT’s tax result; it provides a separate source of wealth if the GRAT is unsuccessful because of the grantor’s premature death.
If the grantor passes before the term, and some or all, the assets are included in the grantor’s gross estate, they may receive a step-up in basis.
This is a modest silver lining as it may not fully offset the estate tax advantage a successful GRAT could have created, but it can matter for low-basis assets that would otherwise carry a large built-in gain.
Risk 2: Underperformance
If the trust’s assets fail to outperform the 7520 hurdle rate, no wealth is transferred to the beneficiaries. The annuity payments consume all the assets, and the beneficiaries receive nothing.
In a zeroed-out GRAT, the grantor simply recovers what they put in through annuity payments, and no gift tax is paid, but the time and legal costs of setting up the trust yield no benefit.
This is especially relevant in a high-interest-rate environment, where the hurdle rate is elevated and harder to beat.
Risk 3: Legislative Changes
Congress has periodically considered legislation to restrict or eliminate zeroed-out GRATs, impose minimum term requirements, or require a minimum taxable gift. None of these proposals have become law, yet the risk remains real.
Because GRAT rules may change, individuals considering the strategy should evaluate it under current law with qualified professionals rather than assuming the same terms will remain available indefinitely.
Risk 4: IRS Valuation Disputes
The initial value of the contributed property determines the annuity required to zero out the GRAT. If the IRS later determines that the property was worth more, the required annuity may need to increase.
Properly drafted GRATs often include valuation-adjustment language tied to the value finally determined for federal tax purposes. This can help preserve the intended gift-tax result, but it may require corrective payments, return more property to the grantor, reduce the remainder passing to beneficiaries, and create appraisal and audit costs.
How a GRAT Fits into a Broader Financial Plan
A GRAT does not operate in isolation. It is one tool within a broader estate planning and wealth transfer strategy, alongside other structures such as irrevocable life insurance trusts, spousal lifetime access trusts, charitable remainder trusts, and direct gifting strategies.
The right combination depends on the grantor’s age, health, asset mix, liquidity needs, estate tax exposure, and family goals.
Importantly, a GRAT is created by an estate planning attorney, not a financial advisor. Legal drafting, IRS compliance, trust administration, and annuity payment schedules all require experienced legal counsel.
A fee-only financial advisor can play a complementary role—helping you identify which assets are best suited for a GRAT, modeling wealth transfer under different return scenarios, and coordinating with your estate planning attorney so the strategy fits your investment portfolio and overall financial plan.
