Grantor Retained Annuity Trust (GRAT): 2026 Planning Guide

A grantor retained annuity trust (GRAT) is one of the few estate planning tools that can transfer significant wealth to your heirs at essentially zero gift tax cost. The IRS requires the transfer to be valued using a benchmark interest rate — the §7520 rate, 5.0% in June 2026 — and any appreciation your trust assets earn above that hurdle passes to your beneficiaries free of gift and estate tax. For HNW households with concentrated positions, pre-IPO equity, or business interests expected to significantly appreciate, a properly structured GRAT can remove millions from your taxable estate without using any of your $15M lifetime exemption.

What is a GRAT?

A grantor retained annuity trust is an irrevocable trust governed by IRC § 2702 in which you (the grantor) transfer assets to the trust and retain the right to receive a fixed annuity payment each year for a specified term. At the end of the term, whatever is left in the trust — the "remainder" — passes to your beneficiaries (typically children or a dynasty trust).¹

The taxable gift when you fund a GRAT is calculated by subtracting the present value of the annuity payments you retain from the value of the assets transferred. In a zeroed-out GRAT, the annuity is sized so the present value of your retained annuity exactly equals the assets you transferred — making the taxable gift mathematically close to zero. You use none of your $15M lifetime exemption.

The §7520 hurdle rate

The Section 7520 rate is published monthly by the IRS and equals 120% of the applicable federal midterm rate (AFR), rounded to the nearest 0.2%. It is the IRS's benchmark for valuing retained interests in trusts — including GRATs.³

June 2026 §7520 rate: 5.0% (IRS Rev. Rul. 2026-11). This is the hurdle rate that GRAT assets must exceed for any value to transfer to your heirs.

• If assets return exactly 5.0%, the remainder is zero — the GRAT breaks even and heirs receive nothing, but you also owe no gift tax. Your downside is the trust's legal fees and your time.
• If assets return more than 5.0%, the excess accumulates in the trust and passes to heirs gift-tax-free at the end of the term.
• If assets return less than 5.0% (or decline), the trust "fails" — all assets are eventually returned to you via annuity payments, and no value transfers to heirs. Again, no gift tax owed, no exemption lost. The cost is only fees.

This asymmetry is the key feature: GRAT wins if assets outperform; GRAT is a wash if they underperform. Heads you win, tails you don't lose (much).

Zeroed-out GRAT mechanics

The IRS allows the annuity payment to be structured so the taxable gift is zero (or close to it, as the minimum gift is technically $0 under the Walton GRAT doctrine).⁴

The annual annuity payment in a zeroed-out GRAT is calculated as:

Where V = asset value, r = §7520 rate (5.0% = 0.05), n = term in years, A = annual annuity payment.

Example — $5M GRAT, 5-year term, 5.0% §7520 rate:

• Annuity factor = (1 − 1.05⁻⁵) / 0.05 = (1 − 0.7835) / 0.05 = 4.329
• Annual annuity payment = $5,000,000 / 4.329 = $1,154,873/year
• Taxable gift ≈ $0 (PV of 5 annuity payments of $1,154,873 at 5% = $5M)

The trust then holds your $5M position. If it grows at 10%/year:

• Year-end value each year: asset grows 10%, then the annuity is paid back to you
• After 5 years, trust remainder = $5M × 1.10⁵ − $1,154,873 × (1.10⁵−1)/0.10 ≈ $8,053K − $7,057K = ~$997,000 to heirs, gift-tax-free

Who benefits most from a GRAT?

1. Pre-IPO founders and early employees

A founder transferring private company stock at a low-valuation stage can lock in the §7520 rate as the hurdle. When the IPO or acquisition occurs at 10x–50x the transfer value, virtually all of that appreciation passes to heirs (or a dynasty trust) with no gift or estate tax. The 30-day deadline for §83(b) elections (for restricted stock) can sometimes be coordinated with GRAT funding — a strategy that requires careful timing with your estate attorney and tax advisor.

2. Executives with concentrated public stock

For executives in blackout periods or under 10b5-1 plan constraints, a GRAT provides a tax-efficient way to begin transferring concentrated-position appreciation without triggering a sale. Annuity payments can be made in-kind in shares (at FMV at time of payment), allowing the trust to retain the position's upside while annuity payments "step up" your estate-held shares.

3. Business owners before a sale

Closely-held business interests are among the most GRAT-favorable assets. If the appraised value for GRAT funding (which may include valuation discounts of 20–40% for minority interest and lack of marketability) is $5M, but the business sells for $12M in year 3, the gain above the §7520 hurdle passes to heirs tax-free. Coordinate with the business exit planning guide for the interaction with IRC § 453 installment sales and §1042 ESOP elections.

4. HNW investors with high-return alternative assets

Private equity, venture investments, or real assets with expected returns well above 5.0% are strong GRAT candidates. Liquid public securities with expected returns near 5.0%–7.0% may not generate enough excess return to justify the effort given today's higher hurdle rate environment.

Rolling GRAT strategy

Because GRAT failure (assets underperforming the hurdle) produces no gift tax or exemption loss, HNW planners often run a series of consecutive short-term GRATs rather than one long-term GRAT. This is the "rolling GRAT" or "cascading GRAT" strategy.⁵

How it works: Instead of a single 5-year GRAT on $5M, you fund a new 2-year GRAT each year (or each quarter). As each GRAT matures, the remainder (if any) is contributed to the next GRAT or to a dynasty trust. Annuity payments from maturing GRATs can be recycled into new GRATs.

Advantages of rolling GRATs:

• Mortality risk mitigation. The primary risk of any GRAT is that the grantor dies during the term — if you die before the GRAT expires, the trust assets are pulled back into your estate (the retained annuity is valued using estate tables, effectively undoing the GRAT). Short-term GRATs limit this exposure.
• Interest rate flexibility. If the §7520 rate drops (making GRATs more efficient because the hurdle is lower), you can immediately fund a new GRAT at the lower rate. Long-term GRATs lock in the rate at funding.
• Volatility harvesting. Short-term GRATs on volatile assets (public equities, SPAC positions, post-merger stock) let you capture upside in a strong quarter without being locked in for years of underperformance.

Disadvantage: Rolling GRATs require ongoing legal fees (each new GRAT is a separate trust instrument), trustee administration, and tax reporting. The overhead cost can make them impractical for positions below $1M–$2M.

GRAT vs. other wealth transfer tools

GRAT + dynasty trust: the two-step sequence

One of the most effective GRAT strategies for UHNW households is the GRAT-to-dynasty-trust sequence, mentioned in the generation-skipping trust guide:

1. Fund a zeroed-out GRAT with the high-growth asset. No gift tax, no exemption used.
2. At GRAT termination, contribute the remainder (the appreciated excess above the §7520 hurdle) to a dynasty trust funded with GST exemption.
3. Allocate GST exemption to the dynasty trust at the time of the GRAT-to-trust transfer, based on the value of the remainder at that time — typically much smaller than the original GRAT asset value, so the GST exemption allocation is efficient.

This sequence removes significant appreciation from the estate while using very little GST exemption — because the GRAT does the heavy lifting of stripping growth above 5.0%, and the dynasty trust captures that net gain permanently.

GRAT risks and limitations

Grantor mortality risk

If you die during the GRAT term, the IRS treats the entire trust as part of your estate — you've lost the GRAT. This is the most significant structural risk. Mitigation strategies: short-term GRATs (2–3 years), term life insurance for the GRAT period, or structuring the GRAT so the annuity is payable to your estate if you die early (which at least recovers your cost basis).¹

§7520 rate environment

At 5.0% in June 2026, the hurdle rate is meaningful. A diversified equity portfolio returning 7%–8% long-run will generate modest GRAT remainders. The strategy is most powerful for concentrated positions or alternative assets with expected returns of 12%+ — or when the §7520 rate drops below 3%. Monitor the monthly rate; consider funding when rates tick down.

Legislative risk

Various Congressional proposals (including the "GRATs Act" in the Senate Finance Committee) have proposed requiring minimum 10–15 year GRAT terms and a minimum taxable remainder of 25% of transferred assets — which would effectively end zeroed-out GRATs. As of June 2026, no such legislation has been enacted. The OBBBA (July 2025) did not address GRATs. Practitioners consider the legislative risk real but low given the current political environment. If you're planning to use a GRAT for a time-sensitive event (pre-IPO, pre-close), act now rather than waiting to see what Congress does.⁶

No basis step-up

Assets in the GRAT (and its remainder) do not receive a step-up in basis at your death — because they're not in your estate. If low-basis appreciated assets pass via GRAT remainder to heirs who intend to sell, they'll owe capital gains tax on the full appreciation. Weigh this against the estate tax savings for each specific asset.

No charitable deduction, no QCD

GRAT annuity payments must be fixed dollar amounts (or a fixed percentage of the initial contribution). Charitable GRATs (CLATs) are a separate instrument. You cannot fund a GRAT with retirement accounts or QCD-eligible assets. See the charitable lead annuity trust guide for the charitable counterpart.

GRAT funding mechanics and IRS compliance

• Valuation at funding. The transfer to the trust is a gift, and the gift value is determined by a qualified appraisal (for closely-held assets) or FMV (for public securities) at the date of transfer. If the asset is difficult to value (private company, illiquid partnership), the appraisal quality directly affects IRS scrutiny risk.
• IRC § 2702 strict compliance. The GRAT must be irrevocable, the annuity must be a fixed dollar amount (not a percentage of trust value that fluctuates), and annuity payments must be made at least annually. Qualified annuity interests under § 2702(b) — confirmed in Walton v. Commissioner — allow the zeroed-out structure. Any deviation (discretionary distributions, variable annuity, retained power) can collapse the § 2702 exception and result in a full gift of the transferred amount.⁴
• Form 709 reporting. You must file a gift tax return (Form 709) for the year of GRAT funding, even if the taxable gift is zero. The return reports the transfer and the § 2702 retained interest calculation. Failure to file starts the statute of limitations running.
• Annuity payment mechanics. Payments can be made in cash or in-kind (shares at FMV on payment date). In-kind payments allow the trust to retain the position while you receive equivalent value. This is common for illiquid or restricted assets.
