14 Jul The Spousal Lifetime Access Trust: How Wealthy Couples Move Assets Out of Their Estate Without Losing Access
A client I work with, a business owner in his mid-50s, came to me with a straightforward concern. He and his wife had accumulated significant wealth. Their combined estate was well above the federal estate tax exemption. He understood that, at current rates, 40% of every dollar above the exemption would go to the IRS at death. He wanted to do something about it.
But he had a condition that I hear often: “I’m not ready to give up access to everything.”
That’s the tension at the core of advanced estate planning. The most powerful tax-saving tools require you to give up ownership of assets. The federal estate tax only applies to what you own at death. So to reduce the tax, you need to move assets out of your estate while you’re alive. But most people, reasonably, don’t want to hand over their wealth with no way to benefit from it if they need to.
A Spousal Lifetime Access Trust, or SLAT, addresses that tension directly.
What Is a SLAT?
A SLAT is an irrevocable trust that one spouse creates and funds for the benefit of the other spouse and, typically, their descendants. The spouse who creates the trust (the “grantor” or “settlor”) transfers assets into it. Those assets are removed from the grantor’s taxable estate. The other spouse (the “beneficiary spouse”) can receive distributions from the trust during his or her lifetime, at the discretion of the trustee.
Think of it this way. You own a house and you’re worried about a flood. You can’t move the house. But you can move your valuables to higher ground, where a trusted person holds them for your family. You no longer own the valuables, so they’re not at risk. But your family still has access to them.
That’s what a SLAT does with your wealth and the estate tax.
How the Tax Benefit Works
When you transfer assets to a SLAT, you’re making a gift. That gift uses a portion of your lifetime gift and estate tax exemption, which under OBBBA is now set at $15 million per person ($30 million per married couple, adjusted for inflation). If your transfer stays within your available exemption, no gift tax is due. The assets, and all future growth on those assets, are out of your taxable estate for good.
This is the part that surprises people. The growth matters as much as the initial transfer. If you move $5 million into a SLAT and it grows to $12 million over 15 years, that $7 million in growth was never in your estate. At 40% estate tax, that is $2.8 million in taxes your family never pays.
A SLAT is typically structured as a “grantor trust” for income tax purposes. That means the grantor, not the trust, pays income tax on the trust’s earnings. This is actually a benefit. Every dollar of income tax the grantor pays is, in effect, a tax-free gift to the trust beneficiaries. The trust’s assets grow without being diminished by income taxes. For more on this strategy, see Why the Wealthiest Families Pay Their Trust’s Income Tax on Purpose.
Why “Access” Is the Key Word
The reason SLATs have become so popular is the indirect access they provide. If the grantor spouse needs funds, the beneficiary spouse can use distributions from the SLAT to cover household expenses, pay for travel, or fund the couple’s lifestyle.
The grantor can’t be a beneficiary of the SLAT. That would pull the assets back into the grantor’s estate for tax purposes under IRC Section 2036. But the beneficiary spouse’s access creates a financial safety net. As long as the couple stays married, the assets remain within reach.
The trust can also make loans to the grantor. A properly structured loan at the applicable federal rate is not a distribution and does not trigger estate tax inclusion. This adds another layer of flexibility.
The Reciprocal Trust Trap
Here’s where the planning gets tricky. If both spouses want the protection and tax savings of a SLAT, the natural instinct is to have each spouse create a SLAT for the other. Husband creates Trust A for Wife. Wife creates Trust B for Husband. Each spouse is a beneficiary of the other’s trust.
The IRS has a doctrine designed to attack exactly this arrangement. It’s called the Reciprocal Trust Doctrine, and it comes from a 1969 Supreme Court case. The court held that when two trusts are “interrelated” and leave the settlors in “approximately the same economic position as if they had created trusts naming themselves as life beneficiaries,” the IRS can “uncross” the trusts. That means the IRS treats each spouse as if they created a trust for their own benefit, which defeats the entire purpose of the planning.
This is a serious risk, and it can be managed, but only with careful drafting. Cookie-cutter mirror trusts are the easiest target for the IRS. I wrote about this in detail here: The Reciprocal Trust Doctrine and Your SLAT.
Creditor Protection
A SLAT, when properly structured as a third-party trust with a spendthrift clause, offers strong creditor protection. Assets inside the trust are generally beyond the reach of the grantor’s creditors, because the grantor has no beneficial interest in the trust. They are also protected from the beneficiary spouse’s creditors, because the beneficiary’s interest is discretionary and subject to a spendthrift provision.
For business owners, doctors, real estate investors, and anyone else with meaningful liability exposure, this protection is not a secondary benefit. It is often the primary reason to consider a SLAT in the first place.
Risks to Understand Before You Act
A SLAT is irrevocable. You can’t take the assets back. That means you need to think carefully about what you transfer and what you keep. A common mistake is transferring too much, too fast, leaving the grantor spouse without enough liquid assets to maintain their own financial security.
Divorce is the other major risk. If the grantor and beneficiary spouse divorce, the beneficiary spouse may still have access to the trust assets, but the grantor spouse has no legal claim. The trust was designed to benefit the other spouse, and a divorce doesn’t change the trust terms. Some practitioners build in a “floating spouse” provision, which defines the beneficiary spouse as whoever is married to the grantor at any given time, but this adds complexity and should be discussed with your attorney.
Death of the beneficiary spouse is another concern. If the beneficiary spouse dies first, the grantor loses indirect access to the trust assets. The trust continues for the descendants, but the grantor can’t receive distributions. Life insurance is sometimes used to hedge this risk.
Who Should Consider a SLAT?
A SLAT is best suited for married couples whose combined estate exceeds the federal exemption (or who live in a state with state-level estate tax exposure) and who want to reduce their estate tax exposure without completely giving up access to the transferred assets. It’s especially relevant for couples who own businesses, hold appreciated investments, or have assets they expect to grow significantly over time. For a broader look at estate planning for business owners, see Estate Planning for Business Owners.
A SLAT is not the right tool for everyone. Couples who aren’t financially comfortable making irrevocable transfers should consider other options. Couples with marital instability should think twice. And anyone considering a SLAT needs to understand the difference between revocable and irrevocable trusts. I explain that distinction here: Trusts: Revocable vs. Irrevocable.
The Bottom Line
The federal estate tax is a 40% tax on wealth above the exemption. For families with estates above that line, the math isn’t subtle. A SLAT is one of the most practical tools available to reduce that exposure while preserving indirect access to the wealth you transfer. But it requires careful structuring, a clear understanding of the risks, and an attorney who knows how to draft trusts that will hold up under IRS scrutiny.
Timing matters. In 2026, the federal exemption is $15 million per individual, but state estate tax exemptions are often much lower, and state legislatures are unpredictable. For families with exposure to both federal and state estate taxes, acting sooner gives you more options.
