In the world of estate planning, staying ahead of tax laws may provide benefits. With the $13.61 million per person estate tax exemption set to sunset at the end of 2025,1 many individuals are facing the reality of potential tax implications on their estates. As the exemption is poised to drop back to the prior level of $5 million per person, adjusted for inflation, the time to start planning is now—perhaps even yesterday.
The Spousal Lifetime Access Trust (SLAT) can be an effective tool in estate planning. This method aids in reducing estate taxes for beneficiaries and potentially provides protection for assets from creditors. A SLAT is an irrevocable trust which permits one spouse, known as the donor spouse, to transfer assets to a trust that will benefit the other spouse and possibly other family members.
So, how does a Spousal Lifetime Access Trust work exactly?
- Establishment and Funding: The donor spouse establishes the trust and funds it with a gift. Importantly, this gift is not taxable because the donor spouse uses their lifetime gift and estate tax exemption; up to $13.61 million per person until the end of 2025.
- Indirect Benefit: While a SLAT is irrevocable, the donor spouse may still indirectly benefit from it as long as they remain married to the beneficiary spouse. This is because the beneficiary spouse can request distributions from the trustee to "maintain their standard of living."
- Tax-Free Transfer: Upon the spouse's death, any remaining assets in the trust are transferred to the remaining trust beneficiaries free from estate taxes, making a SLAT an attractive tool for estate planning purposes.
However, there are important considerations to keep in mind when establishing a SLAT:
- Gift Tax Consequences: Funding a SLAT uses up a portion of the donor's lifetime gift and estate tax exemption, potentially leading to gift tax liability if funded over the exemption.
- Potential for "Trust Cloning": It's essential to avoid the 'reciprocal trust doctrine,' which could lead to the IRS undoing the trust and including the assets in each spouse's taxable estate. The reciprocal trust doctrine is a court-recognized rule that can prevent tax avoidance when assets are transferred to multiple trusts with overlapping donors and beneficiaries.
- Asset Selection: The type of assets used to fund the trust can significantly impact its performance and tax efficacy. Funding the trust with appreciating assets is usually beneficial.
- Impact on Lifestyle: The beneficiary spouse can only request distributions for health, education, maintenance, or support.
- Loss of Step-Up Basis: Assets in a SLAT do not receive a step-up in cost basis upon the donor's death.

Spousal Lifetime Access Trusts provide a strategic approach for people looking to reduce tax burdens and safeguard assets for upcoming generations. With a deep understanding of SLATs' subtleties and factors to consider, individuals can more confidently and calmly handle the intricacies of estate planning.
To sum up, the impending alterations in estate tax laws underscore the significance of forward-thinking estate planning.
