For many couples, lifetime gifting strategies raise an immediate, practical objection: what if we need that money later? A Spousal Lifetime Access Trust (SLAT) is one of the few wealth transfer tools built to answer that question directly, by allowing continued indirect access to gifted assets through a spouse.
How a SLAT works
One spouse (the "donor spouse") establishes and funds an irrevocable trust for the benefit of the other spouse (the "beneficiary spouse"), and often for children or grandchildren as well. The donor spouse allocates gift tax exemption to the transfer. Once completed, the gifted assets — along with all future appreciation — are removed from the donor spouse's taxable estate.
Because the beneficiary spouse can typically receive trust distributions for health, education, maintenance, and support (or under a broader standard, depending on how the trust is drafted), the couple retains a practical, if indirect, connection to the wealth. If the beneficiary spouse later needs funds, the trust may be able to provide them — while the assets remain outside both spouses' taxable estates.
Why timing matters
SLATs are especially relevant when there is meaningful uncertainty about the future of the federal gift and estate tax exemption. Exemption amounts are set by legislation and have changed materially over time; a transfer made while the exemption is available generally locks in that benefit for the transferred assets, even if the exemption is reduced in the future. For families with wealth approaching or exceeding the exemption amount, this creates a "use it or risk losing it" dynamic that has driven significant SLAT planning activity in recent years.
The reciprocal trust problem
A common instinct is for both spouses to create SLATs for each other, doubling the amount of exemption used. This is where SLAT planning gets technically demanding. If the two trusts are too similar in their terms, timing, and funding, the IRS may apply the "reciprocal trust doctrine" and effectively unwind them — treating each spouse as the beneficiary of the trust they created, which defeats the purpose of the strategy.
Avoiding this outcome requires deliberately differentiating the two trusts: different trustees, different beneficiaries or distribution standards, different funding assets, different effective dates, and other substantive distinctions. This is not a do-it-yourself exercise; it requires experienced trust and estate counsel working alongside your financial advisor.
Other risks to plan around
- Divorce. Because the beneficiary spouse's access depends on the marriage remaining intact, divorce can eliminate the donor spouse's indirect access to the trust.
- Death of the beneficiary spouse. If the beneficiary spouse predeceases the donor spouse, the donor spouse's indirect access likewise ends, unless the trust is drafted with contingent provisions addressing this.
- Loss of control. The gift is irrevocable. Even with spousal access built in, the donor spouse gives up direct control over the assets and cannot simply reclaim them.
Who should consider a SLAT
SLATs tend to make sense for married couples with wealth at or approaching the estate tax exemption threshold, who are comfortable making a substantial irrevocable gift, and who want to preserve some indirect, contingent access to the gifted assets through the marriage.
Building this correctly
At SSG Financial Group, we coordinate closely with estate planning counsel to structure SLATs — including addressing the reciprocal trust issue when both spouses wish to use the strategy — and we help model the exemption usage against a family's full balance sheet, so the decision reflects the complete wealth transfer plan rather than a single transaction.
If a SLAT may fit your circumstances, reach out to discuss your options before exemption levels or your personal circumstances change.
