Estate planning can feel overwhelming, especially when navigating tax laws and trying to safeguard your wealth for the future. For high-net-worth (HNW) married couples, one strategy worth considering is the creation of a Spousal Lifetime Access Trust (SLAT).

While the acronym may sound complex, SLATs are far from a “dirty word.” Instead, they present an elegant solution for couples looking to preserve their assets while ensuring financial peace of mind.

Why Estate Planning Matters

The importance of estate planning cannot be overstated, particularly in today’s shifting tax environment. Over the past 15 years, uncertainty surrounding estate tax exemption limits has created challenges for planners and families alike.

The Tax Cuts and Jobs Act (TCJA), enacted in 2017, significantly increased the federal gift and estate tax exemption. However, this provision is scheduled to sunset at the end of 2025.

Without new legislation, the exemption will revert to approximately $6.8 million per individual—about half of the current $13.99 million—starting January 1, 2026.  While there is ongoing debate in Congress, and some proposals aim to extend or expand the current exemption levels, the outcome remains uncertain under the new administration. 

As a result, many high-net-worth couples are proactively exploring strategies to lock in today’s favorable exemption levels. This is where SLATs come into play – offering a strategic and flexible solution to preserve wealth across generations.

Introduction to Spousal Lifetime Access Trusts (SLATs)

A Spousal Lifetime Access Trust (SLAT) is an irrevocable trust that allows one spouse (the donor) to transfer assets to the trust while enabling the other spouse (the beneficiary) to access and potentially benefit from these assets during their lifetime.

At the core, SLATs serve as a powerful estate planning tool to reduce taxable estates while providing financial flexibility to married couples.

Key Benefits of a Spousal Lifetime Access Trust

Estate Tax Mitigation

SLATs allow couples to remove assets from their taxable estate. This is especially beneficial for HNW couples facing potential estate tax exposure. Utilizing the exemption now through strategies like SLATs can lock in tax savings and ensure potential increases in wealth will not be subject to transfer taxes in the spouses’ estates.

Asset Protection

Assets held within SLATs are shielded from creditors and potential lawsuits, offering financial security for the beneficiary spouse and future generations.

Access to Trust Assets

The beneficiary spouse retains indirect access even though the assets are no longer within the donor’s estate. This unique feature ensures flexibility without compromising the estate tax advantages of the trust.

Generational Wealth Transfer

SLATs allow couples to build generational wealth by providing a structure for transferring assets to their heirs while limiting estate tax exposure for future generations.

How SLATs Work

Understanding the operational structure of a Spousal Lifetime Access Trust is essential for anyone considering this estate planning option.

Creation and Funding

The donor spouse establishes the SLAT and funds it using their unified estate and gift tax exemption. Typical funding assets include cash, securities, or even business interests.

Beneficiary Access

The beneficiary spouse can receive distributions from the SLAT during their lifetime. While these distributions are at the trustee’s discretion, they provide financial security and flexibility for the couple.

Irrevocability

A SLAT is an irrevocable trust, meaning that once the assets are transferred, the trust’s terms cannot be changed. This feature is both a benefit and a challenge, as it ensures estate tax exclusion but limits control over the assets.

Remainder Distribution

Upon the beneficiary spouse’s death, any remaining assets in the trust can be passed to other beneficiaries, such as children or grandchildren, free of additional estate taxes and can remain in further trust.

The Risks and Considerations of SLATs

While SLATs offer significant advantages, there are risks and challenges to consider:

  • Loss of Control: Since SLATs are irrevocable, the donor spouse relinquishes control over the trust assets. This can be a difficult adjustment for some individuals.
  • Single Beneficiary Limitation: The SLAT is structured for the benefit of the beneficiary spouse, meaning the donor spouse cannot directly access the trust’s assets should the need arise. However, creative planning, such as reciprocal SLATs, may address this issue.
  • Tax Compliance: Proper drafting and maintenance of the SLAT are critical. Failure to comply with tax regulations can result in unintended consequences, such as disqualifying the trust or including assets back into the taxable estate.
  • Divorce Risk: A key consideration for couples is the potential impact of divorce. Should the donor and beneficiary spouses separate, the SLAT’s assets remain inaccessible to the donor spouse, as the trust terms cannot be altered post-creation.

Why SLATs Continue to Be Relevant

In the past several years, estate planning professionals have highlighted SLATs as a particularly timely tool due to the scheduled sunset of the TCJA’s higher exemption limits in 2025.  While the urgency of the potential sunset may be on hold, SLATs continue to be a valuable estate planning tool that removes asset appreciation from taxable estate.

Additionally, recent years have seen an increased emphasis on asset protection and wealth transfer due to economic volatility and global uncertainty. SLATs address these concerns directly, making them a sound choice for those looking to solidify their financial legacy.
