A Spousal Lifetime Access Trust, often called a SLAT, is an irrevocable trust that allows one spouse to transfer assets out of their estate while still providing financial access for the other spouse during their lifetime. It is commonly used to reduce future estate taxes while keeping a measure of flexibility for married couples.

When structured properly, a SLAT can remove appreciating assets from your taxable estate without cutting off access to those assets entirely. That balance is what makes this trust appealing in higher-value estate plans.

How a Spousal Lifetime Access Trust Works

A SLAT is created by one spouse, known as the grantor, for the benefit of the other spouse, known as the beneficiary. Once assets are transferred into the trust, the transfer is generally irrevocable.

Here is the basic structure:

• You fund the trust with assets such as cash, investment accounts, or business interests.
• Your spouse can receive income from the trust and, depending on how it is drafted, distributions of principal.
• After the beneficiary spouse’s lifetime, remaining assets pass to children or other beneficiaries you choose.

Because the grantor no longer owns the assets, future growth typically stays outside of the grantor’s taxable estate.

Why SLATs Are Used in Estate Planning

SLATs are often part of estate plans designed to address estate tax exposure while maintaining family stability. They can also be useful when planning around changing tax laws or large liquidity events.

Common reasons couples consider a SLAT include:

• Shifting assets out of a taxable estate before exemption amounts change
• Preserving access to trust assets through the beneficiary spouse
• Protecting long-term family wealth for future generations

A SLAT is rarely a standalone solution. It works best when coordinated with other trusts, beneficiary designations, and long-term planning goals.

Key Benefits of a Spousal Lifetime Access Trust

Asset Protection Benefits

Assets placed into a properly structured SLAT are generally protected from the grantor’s creditors. In many cases, they are also protected from the beneficiary spouse’s creditors, depending on how distributions are handled and state law considerations.

This makes SLATs useful for families concerned about lawsuits, professional liability, or future claims.

Estate and Gift Tax Advantages

Funding a SLAT is considered a completed gift for tax purposes. That means the value of the assets, plus future appreciation, is typically removed from your taxable estate.

When structured carefully, a SLAT can:

• Use available lifetime gift tax exemption
• Remove future growth from estate tax calculations
• Reduce estate tax exposure for high-value estates

These benefits become more meaningful as asset values increase over time.

Continued Access Through Your Spouse

Although you cannot directly access trust assets after funding a SLAT, your spouse can. This indirect access often provides comfort for couples who want to reduce estate taxes without locking away funds permanently.

That access must be handled carefully to avoid undermining the trust’s tax treatment.

Potential Risks and Limitations to Understand

SLATs offer benefits, but they are not without trade-offs. Understanding the risks is just as important as understanding the upside.

Loss of Direct Control

Once assets are transferred, you cannot reclaim them or change the trust terms. This lack of flexibility means a SLAT should only be funded with assets you are comfortable parting with long-term.

Divorce or Death of the Beneficiary Spouse

If the marriage ends or the beneficiary spouse passes away, access to the trust assets may be lost. Some plans address this through life insurance or additional trust planning, but it remains a key consideration.

Reciprocal Trust Concerns

If both spouses create SLATs for each other, the trusts must be carefully differentiated. Otherwise, the IRS may treat them as invalid for tax purposes under the reciprocal trust doctrine.

This is an area where drafting details matter.

When a SLAT May Make Sense

A SLAT may be a good fit if:

• You expect your estate to exceed current or future estate tax thresholds
• You are comfortable transferring assets irrevocably
• You want to preserve access for your spouse while planning for heirs
• You are integrating the trust into a broader estate plan

It is less appropriate for families with limited liquidity or uncertain financial needs.

How SLATs Fit Into a Broader Estate Plan

A SLAT works best when coordinated with wills, powers of attorney, beneficiary designations, and other trusts. It should align with your long-term goals for asset management, family support, and tax planning.

We often see SLATs used alongside revocable trusts, irrevocable life insurance trusts, or generation-focused planning strategies.

Planning Ahead With the Right Guidance

A Spousal Lifetime Access Trust can be a powerful planning tool when used thoughtfully and at the right time. It is not a one-size-fits-all solution, and the details matter.
