A Spousal Lifetime Access Trust (SLAT) is an irrevocable trust that allows one spouse to make a gift into a trust that benefits the other spouse, removing assets from the taxable estate while preserving indirect access. When funded with a life insurance policy, a SLAT can serve as a powerful wealth transfer structure for married couples with significant estate planning goals.

Why Life Insurance Is a Natural Fit Inside a SLAT
Many high-net-worth families work with estate planning attorneys to explore how irrevocable trusts can be used to reduce estate tax exposure while preserving family wealth. A SLAT funded with a life insurance policy — particularly an Indexed Universal Life (IUL) or whole life policy — offers a combination of features that attorneys and their clients frequently find worth exploring.
The death benefit passes outside the taxable estate, which is the foundational appeal. But beyond the death benefit, the cash value accumulation inside a permanent life insurance policy grows on a tax-deferred basis. When the trust owns the policy, that growth occurs within a structure designed to keep the asset out of the grantor’s estate, provided the trust is properly drafted and administered. Attorneys often recommend consulting a licensed insurance specialist to structure the policy in a way that complements the trust’s legal design.
One of the more practical advantages that families consider is spousal access. Because the non-grantor spouse is typically a beneficiary of the SLAT, policy loans or withdrawals taken by the trust may be distributed to that spouse during their lifetime. This makes the cash value component of a SLAT-held life insurance policy more accessible than many families initially assume — though the mechanics depend entirely on how the trust document is written.
Gift Tax and Estate Tax Exemption Planning in 2026
The current elevated federal estate and gift tax exemption, established under the Tax Cuts and Jobs Act, is scheduled to sunset at the end of 2025. As we move into 2026, many families face a meaningful shift in exemption levels. This makes 2026 a critical planning window that attorneys and their clients are actively discussing.
A SLAT allows a grantor spouse to use gift tax exemption to fund a trust that will benefit their spouse and other family members. When premium payments for a life insurance policy are made using gifted funds within the SLAT, families may be able to leverage the exemption before it decreases. Attorneys often structure these gifts carefully to comply with annual exclusion rules and Crummey provisions, which is a nuanced area where coordination between the estate planning attorney, the CPA, and a licensed insurance specialist becomes especially important.

Business-Owning Couples: SLATs, Buy-Sell Agreements, and Succession Planning
For married couples who co-own or jointly benefit from a closely held business, the intersection of SLAT planning and business succession planning deserves careful attention. Life insurance is frequently used to fund buy-sell agreements, providing liquidity when an ownership interest must be transferred upon death. When a SLAT holds the life insurance policy, the business owner and their attorney may have additional flexibility in how that death benefit is structured and who controls it.
One approach that business-owning families sometimes explore is using a SLAT-owned life insurance policy as a liquidity tool that supports the surviving spouse’s financial security while also addressing the business transition. The specifics of how this is structured — including the relationship between the SLAT and any separate buy-sell agreement — require close coordination with both the estate planning attorney and business counsel.

SLAT and ILIT Coordination: Avoiding Overlap and Maximizing Structure
Some families use both a SLAT and an Irrevocable Life Insurance Trust (ILIT) as part of a broader estate plan. While these structures can complement one another, they serve different purposes and are not interchangeable. An ILIT is specifically designed to hold life insurance and keep the death benefit out of the insured’s taxable estate, whereas a SLAT is a broader gifting vehicle that may hold various assets, including life insurance.
Attorneys sometimes recommend a SLAT when spousal access to trust assets is a priority, whereas an ILIT may be preferred when the primary goal is pure estate tax exclusion of the death benefit without spousal access considerations. Understanding the distinction matters because the choice affects how beneficiary designations are coordinated and how premium funding flows through the structure.
As a licensed insurance specialist, my role is to work alongside the estate planning attorney and CPA team to ensure the life insurance policy inside either structure is appropriately sized, properly owned, and designed to meet the trust’s stated objectives — not to draft the trust itself, but to make sure the insurance component performs as intended.
Frequently Asked Questions
Can both spouses have a SLAT?
Yes, but reciprocal trusts must be carefully avoided. If both spouses create substantially identical SLATs benefiting each other, the IRS may apply the reciprocal trust doctrine and pull the assets back into each spouse’s estate. Attorneys typically design the trusts with meaningful differences to address this risk. This is one reason why experienced estate planning counsel is essential to any SLAT structure.
What type of life insurance policy is most commonly used inside a SLAT?
Many families and their attorneys consider either whole life insurance or Indexed Universal Life insurance for SLAT funding. Whole life offers predictable cash value growth and a guaranteed death benefit, while IUL provides flexible premiums and cash value growth linked to a market index with downside protection. The right choice depends on the family’s goals, time horizon, and how the trust is structured. You can explore both options through our whole life insurance overview and our IUL resources.
Does the grantor spouse pay taxes on income inside the SLAT?
In many cases, a SLAT is structured as a grantor trust for income tax purposes, meaning the grantor spouse pays income taxes on trust earnings. Some attorneys view this as an additional tax benefit because those payments reduce the grantor’s taxable estate without being treated as a gift. However, this is a complex area of tax law, and families should consult their CPA and estate planning attorney to understand the implications specific to their situation.
