When Should Private Company Owners Use Grantor Retained Annuity Trusts (GRATs)?

August 12, 2026

Selling a private company can trigger one of the largest tax events of a business owner’s life, often with little warning about how much of the sale proceeds will actually reach the next generation. Owners who wait until a term sheet is signed to think about estate planning frequently discover that the window to move value out of their taxable estate has already closed, since many of the most effective strategies only work on assets that have not yet appreciated or been sold.

A grantor retained annuity trust, or GRAT, is one of the tools Quadros, Migl & Kilmer may use to help private company owners move future growth out of their estate before a sale or major liquidity event occurs. We work with business owners across Houston, The Woodlands, Dallas, and Austin, and a GRAT is one of several strategies we may discuss when a client’s business interests, real estate holdings, or investment portfolio make a comprehensive plan more valuable than a basic will.

What A Grantor Retained Annuity Trust Does

A GRAT is an irrevocable trust you fund with an asset you expect to grow in value, often shares in a private company, a partnership interest, or a concentrated stock position. In exchange, you receive fixed annuity payments back from the trust for a set term, which can range from a few years to a decade depending on how the trust is structured.

The annuity payments are calculated using an IRS interest rate published monthly, sometimes called the hurdle rate. If the assets inside the GRAT grow faster than that rate over the trust term, the excess growth may pass to your beneficiaries with little or no additional gift or estate tax owed. If the assets grow more slowly than expected, you simply receive the annuity payments back, and the GRAT ends without the tax benefit, but generally without a significant downside either.

Why Timing Matters For Private Company Owners

A GRAT tends to work best when funded before a known increase in value, which is exactly the position many private company owners find themselves in ahead of a sale, a recapitalization, or a new funding round. Once a letter of intent is signed or a transaction is publicly known, the valuation used to fund the trust may no longer reflect the built-in appreciation that made the GRAT worthwhile in the first place.

Business owners with real estate holdings tied to their company, or with a separate real estate investment portfolio growing alongside the business, sometimes use more than one GRAT to address different assets on different timelines. A distressed oil and gas company anticipating a turnaround, or a mid-size strategic company preparing to be acquired, may have similarly compressed windows where early planning makes a measurable difference in what ultimately reaches heirs.

Weighing The Tradeoffs

A GRAT is not the right fit for every situation, and it carries real tradeoffs alongside its potential benefits. Because a GRAT is irrevocable, you generally cannot undo it once it is funded, and you must survive the trust term for the full tax benefit to apply to your estate.

Before moving forward, it helps to weigh a few practical considerations together with your attorney and financial advisor.

  • Whether the asset you are considering has realistic potential to outperform the current IRS hurdle rate over the trust term.
  • How a multi-year annuity obligation back to you may affect your personal cash flow during the term.
  • Whether your health and life expectancy support surviving the full length of the trust.
  • How a GRAT may fit alongside other tools already in your estate plan, including trusts built around real estate or life insurance.

These questions do not have universal answers, since they depend heavily on your specific assets, your family situation, and how much of your lifetime exemption you want to preserve for other planning.

How A GRAT Fits Into A Broader Plan

A GRAT rarely stands alone in a business owner’s estate plan. It often works alongside a revocable living trust that handles probate avoidance for assets outside the GRAT, or a broader business succession plan that addresses what happens to leadership and ownership after a sale or transition.

The Section 7520 rate used to calculate GRAT annuity payments changes monthly, so the trust that made sense a year ago may look different today, which is one reason business owners often revisit this planning alongside major liquidity events rather than treating it as a one-time decision. Owners who also hold significant life insurance policies as part of their liquidity planning may additionally want to review how an irrevocable life insurance trust interacts with the rest of their estate.
