Spousal Lifetime Access Trust (SLAT): Lock in the $13.61M Exemption Before the Sunset
The Tax Cuts and Jobs Act of 2017 artificially doubled the federal estate and gift tax exemption. Unadjusted for inflation, the base exemption temporarily jumped from $5 million to $10 million. In 2024, scaled for inflation, high net worth individuals can transfer $13.61 million ($27.22 million for a married couple) completely free of estate or gift tax. However, this doubled exemption is statutorily mandated to sunset on December 31, 2025, crashing back down to approximately $7 million per person (inflation-adjusted). The "use it or lose it" race to lock in this historically unprecedented transfer capacity relies predominantly on one vehicle: the Spousal Lifetime Access Trust (SLAT). Our estate architecture team designs and funds SLAT structures for families navigating the sunset timeline.
The Problem: Gifting Away $13.61M Creates Wealth Insecurity
To lock in the $13.61M exemption before it disappears, a taxpayer must make an irrevocable gift of that amount. The IRS has definitively ruled that there will be no "clawback" — meaning if you gift $13 million now, and die in 2027 when the exemption is only $7 million, the IRS will not penalize the estate for the difference. However, for a wealthy individual whose net worth is $20 million, gifting away $13 million permanently to children or an irrevocable trust creates psychological and financial insecurity. What if the donor’s remaining $7 million is decimated by a market crash or severe medical expenses?
A standard irrevocable trust requires the grantor to irrevocably part with dominion, control, and access to the funds. They cannot take the money back. This rigid "no access" rule prevents many wealthy families from utilizing the full exemption window, paralyzing them into inaction.
The SLAT Solution: Indirect Access Through Your Spouse
A Spousal Lifetime Access Trust solves the access problem gracefully. The grantor (e.g., Husband) creates an irrevocable trust and funds it with $13.61 million of his separate property. The beneficiaries of the trust are his children and, critically, his Wife. Because the Husband transferred the assets, he has utilized his $13.61 million gift tax exemption, permanently removing those assets and all future appreciation from his taxable estate.
The breakthrough is the access mechanism. Because the Wife is a beneficiary of the trust, the trustee can make distributions of income and principal to the Wife to support her health, education, maintenance, and support (HEMS standard). When the Wife receives a distribution, she can deposit it into a joint checking account, indirectly allowing the Husband to benefit from the funds. The Husband successfully removed the assets from his taxable estate, locked in the expiring exemption, while the marital unit retained access to the capital as a financial safety net. As a grantor trust, the Husband continues to pay the income taxes generated by the SLAT assets, which serves as an additional, tax-free gift that allows the trust principal to compound unburdened by tax drag. Our HNW tax advisors model this "burn down" effect of the grantor paying trust taxes.
Navigating the Risks: Reciprocal Trust Doctrine and Divorce
If a married couple has $30 million, they often attempt to construct two SLATs — the Husband funds a $13 million SLAT for the Wife, and the Wife funds a $13 million SLAT for the Husband. This triggers the IRS "Reciprocal Trust Doctrine." If two trusts are fundamentally identical and leave the parties in the same economic position as if they had created trusts for themselves, the IRS will "uncross" the trusts, treat each spouse as the grantor of their own trust, and pull the entire $26 million squarely back into the taxable estate. To survive an IRS audit, the two trusts must be demonstrably unequal — different trustees, different distribution standards, different assets funded, and different creation timelines.
The second major risk of a SLAT is the "D" word — Divorce (or Death). Because the Husband’s access to the SLAT is contingent entirely on his marriage to the Wife beneficiary, if they divorce, or if the Wife dies before the Husband, his indirect access is severed. The assets remain in trust for the children, but the Husband's financial safety net disappears. Modern SLAT architecture mitigates this by defining the beneficiary as a "floating spouse" (whoever the grantor is married to at a given time) rather than a specific named individual, or by integrating life insurance into the trust structure so the Husband receives a death benefit upon the Wife's demise. We coordinate the funding of SLATs through certified Form 709 gift tax filings to ensure the exemption is claimed meticulously.
