Spousal Lifetime Access Trust (SLAT)

An irrevocable trust created by one spouse for the benefit of the other spouse, removing assets from the grantor's taxable estate while maintaining indirect access to the trust funds through the beneficiary spouse.

Definition

A Spousal Lifetime Access Trust is an irrevocable trust created by one spouse (the grantor) for the primary benefit of the other spouse (the beneficiary). The grantor uses a portion of their lifetime gift tax exemption to fund the trust, removing those assets from both spouses' taxable estates. Because the non-grantor spouse is a beneficiary, the couple retains indirect access to the trust's income and principal through distributions to the beneficiary spouse.

The SLAT solves the fundamental tension in estate planning: how to remove assets from the taxable estate without losing access to them entirely.

How It Works

Spouse A creates a SLAT and funds it with assets, using Spouse A's lifetime gift tax exemption. The trust names Spouse B as a beneficiary (along with children or other heirs). An independent trustee manages the trust and makes distributions to Spouse B according to the trust's terms, typically based on an ascertainable standard such as health, education, maintenance, and support.

Because the trust is irrevocable, the assets are removed from Spouse A's taxable estate. Because Spouse B can receive distributions, the couple maintains a financial safety net. All appreciation on trust assets occurs outside both spouses' estates.

When both spouses want to create SLATs for each other, the trusts must differ in meaningful ways (different assets, different terms, different trustees, different funding dates) to avoid the reciprocal trust doctrine. Under this doctrine, the IRS can collapse identical cross-trusts and pull the assets back into the taxable estates. Careful drafting by an experienced estate attorney is essential.

When Entrepreneurs Use This

Exemption locking: Using the current elevated lifetime exemption ($13.99 million per person in 2025) before a potential reduction by Congress
Business owner couples: One spouse transfers business interests into a SLAT while the other spouse retains access to distributions
Maintaining lifestyle access: Entrepreneurs who want estate tax reduction but are not comfortable losing all access to the transferred wealth
Generational planning: SLATs can be structured as dynasty trusts, benefiting the spouse during their lifetime and then continuing for children and grandchildren

Dew Wealth Perspective

The SLAT has become one of the most popular estate planning vehicles since the Tax Cuts and Jobs Act (TCJA) doubled the lifetime exemption in 2018. The exemption is scheduled to sunset at the end of 2025, potentially dropping by nearly half. Entrepreneurs who have not yet used their exemption face a closing window to lock in the higher amount.

The Linchpin Partner models the financial impact of funding a SLAT at various levels, factoring in the couple's liquidity needs, risk tolerance, and the probability of exemption reduction. The key risk is divorce: if the beneficiary spouse is no longer part of the family, the grantor loses all indirect access to the trust assets.

Frequently Asked Questions

What happens if we get divorced?

The grantor spouse loses indirect access to the SLAT because distributions flow to the beneficiary spouse. This is the primary risk of a SLAT and must be weighed carefully before funding. Some trust documents include provisions that shift beneficiaries upon divorce.

Can both spouses create a SLAT?

Yes, but the trusts must be meaningfully different to avoid the reciprocal trust doctrine. Different assets, terms, trustees, and timing help establish the trusts as independent arrangements.

What if the exemption does not decrease?

The SLAT still provides estate tax protection on all future growth of the transferred assets. Even if the exemption remains high, the appreciation inside the trust accumulates outside the taxable estate, which benefits families with growing asset bases.
