For high-net-worth individuals and families in New York, preserving wealth across generations requires more than a basic will or revocable trust. Estate tax exposure, capital gains liabilities, and the complexities of transferring appreciating assets demand sophisticated planning strategies. One of the most powerful tools available under current tax law is the Intentionally Defective Grantor Trust (IDGT)—a planning vehicle that, when properly structured, can transfer significant wealth to heirs with minimal tax consequences.
Our New York attorneys focus on advanced estate and trust planning for clients with substantial assets, closely held business interests, real estate portfolios, and concentrated investment positions. We design and implement IDGT structures tailored to each client's financial circumstances, family dynamics, and long-term legacy goals.
An Intentionally Defective Grantor Trust is an irrevocable trust drafted to be treated differently for income tax purposes than for estate and gift tax purposes. The term "defective" is somewhat misleading—the trust is not flawed; rather, it is intentionally structured to take advantage of a specific feature in the federal tax code.
Specifically, an IDGT is designed so that:
This dual treatment creates remarkable planning opportunities. Because the grantor pays the income tax on trust earnings personally, the trust assets grow undiminished by tax—effectively allowing the grantor to make additional tax-free gifts to beneficiaries every year in the form of the income tax payments.
New York imposes its own estate tax in addition to the federal estate tax, and the New York estate tax has a notorious "cliff" provision: estates that exceed the New York exemption by more than 5% lose the entire exemption and pay tax on the full estate value. With the New York estate tax exemption substantially lower than the federal exemption, many families who would owe no federal estate tax still face significant New York estate tax liability.
An IDGT can be a critical component of a strategy to:
While an IDGT can simply be funded through a gift, the most powerful technique combines a small seed gift with an installment sale to the trust. This is often referred to as a "sale to a defective grantor trust."
The grantor first makes a gift to the IDGT, typically equal to at least 10% of the value of the assets that will later be sold to the trust. This gift establishes economic substance and uses a portion of the grantor's lifetime gift tax exemption.
The grantor then sells appreciating assets—such as closely held business interests, real estate, or marketable securities—to the trust in exchange for a promissory note. The note bears interest at the applicable federal rate (AFR), which is generally lower than expected investment returns.
Because the grantor and the trust are treated as the same taxpayer for income tax purposes, the sale triggers no capital gains tax, and interest payments on the note are not taxable income to the grantor. Any appreciation above the AFR passes to the trust beneficiaries free of gift and estate tax.
IDGTs are not appropriate for every client, and they require careful drafting and ongoing administration. Important considerations include:
An IDGT is generally most beneficial for individuals and families who:

An IDGT should never exist in isolation. We work to integrate IDGT planning with other components of a comprehensive estate plan, including revocable living trusts, irrevocable life insurance trusts (ILITs), grantor retained annuity trusts (GRATs), charitable remainder trusts, and family limited partnerships. The goal is a cohesive structure that addresses estate tax, income tax, asset protection, business succession, and family governance.
