Spousal Lifetime Access Trusts

A Spousal Lifetime Access Trust, commonly known as a SLAT, is an advanced estate planning strategy frequently used by high-net-worth families seeking to reduce future estate tax exposure while maintaining indirect access to transferred assets.

Under a SLAT arrangement, one spouse creates an irrevocable trust for the benefit of the other spouse and, often, descendants. Assets transferred into the trust are removed from the grantor spouse’s taxable estate, potentially reducing future estate taxes. The beneficiary spouse may receive distributions under the trust terms, providing a measure of financial flexibility for the family unit.

A unique feature of a SLAT is that while the transferred assets are generally no longer owned by the grantor spouse, the beneficiary spouse may continue to benefit from the trust. This indirect access can provide comfort for families concerned about giving away substantial wealth during life.

SLATs often take advantage of available federal gift and estate tax exemptions. By making completed gifts during life, families may lock in favorable tax treatment and shift future appreciation outside the taxable estate. When trust assets grow over time, the long-term tax savings can be significant.

Trust assets can be invested and managed for long-term growth. SLATs may also provide creditor protection and preserve assets for future generations. Depending on the drafting, the trust can include descendants, sprinkle distribution authority, trustee discretion, and generation-skipping planning features.

Despite their benefits, SLATs require careful design. The beneficiary spouse’s death or divorce can significantly alter the planning outcome. If the beneficiary spouse is no longer available as a source of indirect access, the grantor spouse may lose the practical comfort that motivated the planning. For this reason, SLAT planning should be aligned with broader financial projections.

When both spouses establish trusts for each other, planners must avoid the reciprocal trust doctrine, which can cause adverse tax consequences if the trusts are too similar. Differences in timing, trustees, beneficiaries, distribution standards, and trust terms may be important.

SLATs are often used in conjunction with other sophisticated planning techniques as part of a broader wealth transfer strategy. For families with substantial estates, they can provide a balance between tax efficiency and financial flexibility.
