A grantor retained annuity trust (GRAT) is a way to give your children the future growth of an asset, such as a business, private company stock or a concentrated stock position, while using little or none of your lifetime exemption. It is especially useful for business owners who expect a value increase or a sale.
GRAT, in short: You transfer assets to an irrevocable trust and receive fixed annuity payments back for a set term, often two to ten years. The taxable gift is the value of the assets minus the value of your annuity, calculated using the IRS’s § 7520 interest rate (26 U.S.C. § 2702). If the assets grow faster than that rate, the excess passes to your children or a trust for them at the end of the term, free of gift tax.

Many clients use a series of short-term GRATs, often two years each, and roll each annuity payment into a new GRAT. Short terms capture growth in volatile assets and reduce the risk that the grantor dies during the term.
Business owners and real estate investors often hold assets in a family limited liability company or partnership and place non-controlling interests in a GRAT or other trust. Because a minority interest cannot control the company or be easily sold, a qualified appraiser may value it below its share of the underlying assets. The IRS challenges family entities where the parents keep control of the assets or keep using them personally (see Estate of Powell v. Commissioner, 148 T.C. 392 (2017)), so the entity needs a real business purpose and must be run like a business.
GRATs work best for assets with high expected growth and for clients who want to use little exemption. Clients with more exemption to use, or who want to benefit grandchildren, may prefer a gift or sale to a SLAT or dynasty trust. We compare the options with projections before recommending one.
We draft the grantor retained annuity trust and any family LLC agreement, coordinate the appraisal, set up the annuity schedule, and work with your CPA on the gift tax return and the annual payments. See the estate tax planning overview for related strategies.

Some or all of the GRAT assets are included in your estate, roughly putting you back where you would have been without the GRAT. That is why many clients use short-term rolling GRATs.
Assets expected to grow faster than the IRS § 7520 rate, such as interests in a growing business, pre-IPO or pre-sale company stock, or a concentrated stock position.
A zeroed-out GRAT uses little or none, because the value of the annuity you keep equals almost the full value of the assets you contribute.
