Trusts are an essential part of legacy planning, and funding a trust with life insurance is a popular funding method. A common scenario is one in which a spouse passes away and leaves assets to the surviving spouse in the form of a credit shelter trust (also known as a bypass trust, A/B trust or “B” trust). In this scenario, the surviving spouse may or may not need the income generated by these trust assets. If the income is not distributed from the trust, the trust is on the hook for taxes that could be as high as 40.8%. (The top trust tax bracket is 37% + a 3.8% surtax, if applicable.*) The trustee wants to avoid the trust paying tax but does not want to make a distribution of the income out of the trust. So what can be done to avoid the trust paying tax on the income?
In 2017, Reggie Milton passed away and a credit shelter trust was funded with assets worth $5,490,000, which was equal to his available applicable exclusion amount for federal estate tax purposes. Reggie’s surviving spouse, Roberta, is the income beneficiary of the trust, and their children, Roger, Renee and Rosa, are remainder beneficiaries in equal shares. Roberta does not need the income generated by the trust assets; potentially subjecting the trust to significant income taxes.

The trustee uses the credit shelter trust assets to purchase a life insurance policy on Roberta’s life. The trust is named as owner and beneficiary of the life insurance policy, and Roberta is the insured. Upon Roberta’s death, the proceeds of the life insurance policy are paid to the credit shelter trust free of income and estate tax (including the 3.8% Medicare surtax).1 Thereafter, the insurance proceeds can be distributed to Roger, Renee and Rosa — also income and estate tax free.1 By using life insurance as a funding vehicle in the trust, the trustee will be able to take advantage of several of the general benefits and features of life insurance. In addition, the trust can provide distributions during the surviving spouse’s life.2

[1] The surviving spouse must not possess any “incidents of ownership” in the policy under IRC Sec. 2042; for example, if the surviving spouse is a trustee of a credit shelter trust. Please consult with an attorney or legal advisor. The death benefit is not subject to federal income tax unless a taxable transfer for value under IRC Sec. 101(a)(2) is applicable.
[2] If the life insurance policy is a modified endowment contract (MEC), withdrawals of policy cash value may be subject to current income tax, including the 3.8% Medicare surtax.
