Succession & Estate

Intentionally Defective Grantor Trusts

Build the structure that separates income tax ownership from estate tax ownership: the sale for a note at a low rate, the seed capital that makes it real, and the risks that have actually been litigated.

What decision this helps you make: Whether to sell business interests to a grantor trust for a note, how to size the seed gift and set the note terms, and how the structure compares with an annuity trust on your facts.

What this topic is

A trust that is deliberately drafted so that the grantor remains the owner of its assets for income tax purposes while the assets are outside the grantor's gross estate for transfer tax purposes. The grantor typically makes a seed gift to the trust and then sells appreciating assets to it for a promissory note. Because grantor and trust are treated as the same taxpayer for income tax, the sale produces no gain and the interest is neither deductible nor taxable, and the grantor pays the trust's income tax each year, which reduces the estate without being a further gift.

Why it matters

It is the principal alternative to a retained annuity trust and it wins on several dimensions: the hurdle is the applicable federal rate rather than a higher published rate, there is no cliff if the grantor dies during the term, and generation-skipping exemption can be allocated immediately. It also carries risks the annuity trust does not: the structure depends on the grantor trust rules holding, on the note being respected as debt, and on a valuation that has to survive scrutiny.

Who should learn it

Owners of appreciating businesses with a long horizon, estate planners structuring installment sales, and families with an existing structure who need to understand what it depends on.

What you will understand

  • Which powers make a trust "defective" for income tax without pulling the assets back into the estate
  • How the installment sale works, why seed capital matters, and what note terms are defensible
  • The tax burn: why the grantor paying the trust's income tax is the quiet engine of the structure
  • The genuinely unsettled questions, including what happens to the note when the grantor dies

Prerequisites

Common misconception

"Grantor trust status means the assets are still yours." For income tax, yes: you report the income and you pay the tax. For estate tax, no: properly structured, the assets are outside your gross estate. That deliberate split is the whole point, and it produces the single most powerful feature of the structure: every dollar of income tax you pay on the trust's earnings leaves your estate and enriches the beneficiaries, and it is not treated as an additional gift. The mirror misconception is equally wrong: because the assets are outside the estate, they receive no basis adjustment at death.
