Intentionally Defective Grantor Trust: Why It’s a Smart Estate Planning Move

Overview of Intentionally Defective Grantor Trusts

You’ve worked hard to build your wealth. Naturally, you want to pass it on to your loved ones, not the IRS. But without proper planning estate taxes and income taxes combined can significantly shrink what your heirs and beneficiaries receive. 

How does that happen, you might wonder?  When a person dies leaving a high net worth estate the government can tax the value of the estate before it ever reaches the decedent’s heirs. This estate tax can be substantial, and the heirs can only get what is left after the tax amount has been paid.  On top of that, if the assets left (after estate tax) generate income like rental properties, stocks, or businesses, the deceased heirs could also owe income taxes on those earnings. That means they’re not just inheriting wealth; they’re inheriting a tax burden, too.

To avoid future problems like this, many people turn to state planning solutions such as an Intentionally Defective Grantor Trust (IDGT). When structured correctly, an IDGT can help protect your assets and ensure the bulk of your wealth goes to your heirs instead of the government. However, setting up this type of trust requires careful planning. If it’s not done right, you could miss out on key benefits or even create new tax problems unknowingly. If you’re considering this or any other type of trust as an estate planning strategy, legal guidance is essential to ensure that your trust aligns with your goals and current estate planning/tax regulations.

Read in to learn exactly how an IDGT works and why it’s such a smart estate planning move.

What Is an Intentionally Defective Grantor Trust?

An Intentionally Defective Grantor Trust (IDGT) is a special type of irrevocable trust used in estate planning to reduce estate taxes while allowing the assets within the trust assets to grow, income tax-free for the grantor’s (creator’s) beneficiaries.

As an irrevocable trust, the assets inside the trust are treated as separate from the grantor’s estate for estate tax purposes since the grantor has essentially given up ownership by creating the trust. 

Also, in a typical irrevocable trust, the trust, not the grantor, pays income taxes on any earnings from trust assets. However, an IDGT is structured so that the grantor remains responsible for paying income taxes on the trust’s earnings, even though the assets are no longer part of their taxable estate. 

Despite the “defective” in its name, the trust isn’t flawed. The name only reflects that the trust has been intentionally structured to deviate from the norm for irrevocable trusts, generally where the grantor is not considered the owner of the assets in question. Essentially, this so-called “defect” is actually a benefit as far as estate planning is concerned. By covering the trust’s income tax bill, the grantor effectively makes a tax-free gift to the beneficiaries, allowing the trust’s assets to grow without being depleted by taxes while protecting the trust assets from estate taxes. 

Key Features and Benefits of an IDGT

If you’re considering an Intentionally Defective Grantor Trust (IDGT), its key features and benefits are highlighted below:

Reduces Estate Taxes

The trust removes assets from your taxable estate, so any future appreciation isn’t taxed when you pass away.

There are two ways to achieve this;

Gifting Assets to the IDGT

You can transfer assets to the trust outrightly. While this excludes the assets from your estate for estate tax purposes, it reduces your lifetime gift tax exemption ($13.99 million in 2025).

But once the assets are in the trust, any future growth is estate tax-free.

Selling Assets to the IDGT (Estate Freeze)

You could sell assets to the trust in exchange for a promissory note (loan). The value of what you sold is frozen at today’s price. Any future growth happens inside the trust without being taxed in your estate. However, the remaining balance of the loan is still part of your taxable estate. 

This is why it’s called an estate freeze—you “freeze” the taxable value at today’s lower amount while future growth goes to your heirs without extra estate taxes.

Allows Income Tax-Free Growth for Heirs 

 Since you, as the grantor, pay the trust’s income taxes, the assets grow faster without tax burdens on your heirs.

Avoids Capital Gains Tax on Sales 

Selling assets to the trust doesn’t trigger capital gains tax, making it a tax-efficient way to transfer appreciating assets.

By using an IDGT, individuals can preserve more of their wealth, protect their assets, and maintain control over how their estate is managed.

Who Needs an IDGT? 

An Intentionally Defective Grantor Trust (IDGT) is a strategic estate planning tool for families with significant wealth, business owners, and real estate investors.

 If you have assets that are likely to appreciate over time—such as a family business, investment properties, or valuable stocks you might want to consider having an IDGT as part of your estate planning strategy, especially if you can afford to bear the income tax burden from the trust. 

When structured properly, an IDGT can shield assets from creditors, lawsuits, or financial risks, much like a Domestic Asset Protection Trust (DAPT). This is especially beneficial for business owners and professionals in high-liability fields, such as doctors or real estate developers, who want to ensure their wealth remains secure for future generations.

Every individual /family’s financial situation is unique, and estate planning should be tailored to individual goals. Setting up an IDGT requires careful drafting to ensure it aligns with both estate tax and asset protection strategies and your unique needs.

 Can an IDGT Be Modified or Changed?

An Intentionally Defective Grantor Trust (IDGT) is typically irrevocable, meaning it cannot be easily amended or modified once it’s created. However, there are a few ways to introduce flexibility and make small changes to such trusts, including through;

• A Trust Protector: Some IDGTs include a trust protector, a third party with limited powers to modify the trust, such as replacing the trustee or adjusting provisions if laws change.
• Trust Decanting: In some states, including Nevada, the trustee may be able to decant/transfer the assets into a new trust with better terms. This power is limited and must be utilized with caution. 

Other ways to modify an irrevocable trust, such as getting a court order or using a non-judicial settlement agreement, may also be effective in modifying your IDGT, depending on the circumstances. An estate planning attorney can explain your options and help you make an informed decision if you’re looking to amend such a trust.
