Don’t get us wrong. We love estate planning, but have you ever sat through an estate planning meeting and felt like you were being tested on acronyms? You’re not alone. SLATs, IDGTs, QPRTs…

We try not to be jargon-heavy in the weekly note, but some of these oddly named trusts are worth knowing at a high level. Once you understand what they do, awareness can serve as a conversation starter.

Here are five to have on your radar that may introduce a useful estate planning vehicle for what’s most important to you. We’ll outline how each one is used for tax planning, the situations they’re designed to serve, and potential limiting trade-offs.

If you find this resource helpful, please share it with someone who may benefit from the ideas.

1. Spousal Lifetime Access Trust (SLAT)

Think of it as a “have your cake and eat it too” trust. One spouse gifts assets into a trust for the other spouse’s benefit. Those assets (and their growth) are moved out of your estate for tax purposes — yet you can still access them indirectly through your spouse if needed.

How the tax strategy works: The gift uses part of your lifetime estate and gift tax exemption to shift appreciating assets out of your estate now. Future growth happens outside the estate, avoiding estate tax down the road.

When it helps: You’re looking to reduce future estate taxes without giving up all flexibility.

Potential drawback: If the beneficiary spouse passes away or you divorce, that indirect access disappears — so it’s best used in stable, long-term marriages.

2. Irrevocable Life Insurance Trust (ILIT)

This one holds life insurance outside your estate. The result: your heirs receive the policy proceeds free of estate tax.

How the tax strategy works: Because the trust, not you, owns the policy, the death benefit isn’t included in your taxable estate. Premiums are treated as gifts to the trust (often using annual exclusions), and the proceeds pass tax-free to beneficiaries.

When it helps: You have a large estate or illiquid assets (like real estate or business interests) and want insurance proceeds to cover future estate taxes or provide liquidity.

Potential drawback: Once the trust is funded, you can’t change beneficiaries or access the cash value. The “irrevocable” part means you’re giving up control for tax efficiency.

3. Qualified Personal Residence Trust (QPRT)

You transfer your home into a trust, keep living there for a set number of years, and then it passes to your heirs at a reduced tax value.

How the tax strategy works: When you transfer the home, the IRS values the gift based on today’s value minus the right to live there for the trust term. That discount makes the taxable gift smaller. After the term, the home (and future appreciation) is outside your estate.

When it helps: You own a valuable home and want to move future appreciation out of your estate without moving out right now.

Potential drawback: If you don’t outlive the term, the home value is pulled back into your estate. Plus, it limits flexibility like refinancing, moving, or selling can get complicated.

4. Intentionally Defective Grantor Trust (IDGT)

Despite the name, it’s intentionally smart. The “defective” part means the IRS sees you as the owner for income taxes, but not for estate taxes. That allows you to move appreciating assets out of your estate while continuing to pay the income taxes yourself (which further shrinks your taxable estate).

How the tax strategy works: You sell or gift assets to the trust in exchange for a note. The trust grows outside your estate, and you keep paying the income taxes. It effectively makes additional tax-free gifts because your payments reduce your estate without triggering gift tax.

When it helps: You hold appreciating assets like private business interests or investments and want to transfer that growth to future generations efficiently.

Potential drawback: You’re still on the hook for the income taxes, even though the assets are no longer yours, so you need liquidity and a long view to make it worthwhile.

5. Dynasty or Generation-Skipping Trust (GST)

These are long-term legacy tools designed to pass wealth across multiple generations while avoiding estate taxes each time wealth changes hands.

How the tax strategy works: You fund the trust and allocate your generation-skipping transfer (GST) tax exemption. That means future growth (potentially for decades or even centuries) avoids additional estate and GST taxes as it passes from one generation to the next. You’re removing the taxable event that would be the transfer to your children.

When it helps: Your adult children are financially well-off or even independent on their own, and an inheritance would have a greater net benefit when distributed directly to grandchildren.

Potential drawback: They’re complex to administer and can “lock in” wealth for future generations in ways that may feel restrictive. Not every family wants or needs that level of structure.
