Minimizing or avoiding estate taxes is an important estate planning goal for many married couples. The laws concerning estate taxes are frequently discussed in Congress, and there is much uncertainty as to where future laws will land. The exemptions, estate rates, and acceptable planning methods that we know of today, may not be in place in the near future. One approach to consider in light of this uncertainty, that leaves some last-minute flexibility, is the use of a disclaimer and something called a “Clayton election”.

Marital Deduction Planning and Marital Share Funding Formulas

The main objective of using a marital funding formula in estate tax planning is to take advantage of both (1) the estate tax marital deduction and (2) the estate tax exemption to eliminate federal estate tax at the first spouse’s death and to reduce or eliminate federal estate tax due at the surviving spouse’s death.

What is the marital deduction? In general, transfers from a decedent spouse to a surviving US citizen spouse are excluded from the decedent spouse’s estate and are not subject to estate taxes at the first spouse’s death. In essence, there is an unlimited estate tax deduction for transfers between married spouses. This deduction essentially postpones the payment of any estate taxes until after the second spouse’s death.

The general concept of the estate tax exemption is that, if the value of your estate is less than the exemption amount, no federal estate tax is due. The 2022 exemption amount for an individual is $12.06 million. Under current law, the exemption amount will be reduced to $5 million (adjusted for inflation) on January 1, 2026. Also, under current law, a 40 percent tax is imposed on estate assets in excess of the exemption amount.

Marital share funding formulas are used to eliminate federal estate tax to the greatest extent possible. Because the unlimited estate tax marital deduction allows estate tax liability to be postponed until the second spouse’s death, the first decedent spouse’s estate plan should use a formula to divide the their estate into two shares — (1) the marital share, which is the part of the decedent spouse’s estate that passes to the surviving spouse in a form that qualifies for the unlimited estate tax marital deduction, and (2) the nonmarital share, which is the part of the decedent spouse’s estate that does not qualify for the unlimited marital deduction but is instead sheltered by the decedent spouse’s remaining estate tax exemption amount.

Example without a marital share funding formula. Doug and his wife, Ann, each own half of their $25 million estate. Doug dies in 2022, when the estate tax exemption amount is $12.06 million. Ann dies in 2026, when the estate tax exemption amount is only $5 million, increased by the inflation adjustment then in effect. Their estate plan leaves the first decedent’s estate to the surviving spouse with everything going to their children at the surviving spouse’s death.

When Doug dies in 2022, his $12.5 million portion of the estate passes to Ann, qualifying for the unlimited estate tax marital deduction, resulting in no estate tax owed at his death. Because all of Doug’s $12.5 million passes to Ann under the marital deduction, when Ann dies in 2026, the $5 million exemption amount then in place will only protect $5 million of the $25 million estate. With a 40 percent estate tax rate, Ann’s estate would owe $8 million in estate tax.

Example with a marital share funding formula. Let’s assume that all facts are the same as in the above example, except that Doug and Ann’s estate plan uses a marital funding formula dividing Doug’s estate into marital and nonmarital shares. At Doug’s death, $12.06 million is apportioned in trust to the nonmarital share to use all of Doug’s estate tax exemption amount, and the remaining $440,000 is apportioned to the marital share. When Ann dies in 2026, her estate will be worth $12,940,000, consisting of her $12.5 million portion of the estate and the $440,000 apportioned to the marital share from Doug. Ann’s $5 million estate tax exemption amount in 2026 will protect $5 million of Ann’s $12.94 million estate. With a 40 percent estate tax rate, Ann’s estate would owe $3,176,000 in estate tax.

By using a marital share funding formula as part of their estate tax planning, Doug and Ann can save their heirs $4,824,000 in estate taxes.

Disclaimer Planning

There are numerous different ways to divide a couple’s trust property into marital and nonmarital shares upon the first spouse’s death, but the disclaimer option gives the surviving spouse the most flexibility. Using the disclaimer option, the trustee or executor distributes all the decedent spouse’s trust property to the marital share. The surviving spouse may then exercise a qualified disclaimer under Internal Revenue Code section 2518, disclaiming his or her interest in the assets of the decedent spouse, and the trustee then distributes any property disclaimed by the surviving spouse to the nonmarital share, which can be either held in trust for the benefit of the surviving spouse or other beneficiaries or otherwise administered under the terms of the trust.

With the disclaimer option, the surviving spouse is given some flexibility. She can choose to give any amount or property they wish to the nonmarital share, depending on the estate tax law in effect at the time of the first spouse’s death, the value of the decedent spouse’s estate, and the surviving spouse’s financial needs.

Clayton Election

The Clayton election, named after the court case Estate of Clayton, Jr. v. Commissioner, is another formula used to divide a couple’s trust property into marital and nonmarital shares. It also provides maximum flexibility to engage in marital deduction planning after the first spouse’s death. The Clayton election works in almost the opposite of the disclaimer option. Instead of distributing all the decedent spouse’s trust property to the marital share, the trustee distributes it to the nonmarital share. The trustee may then list any property on Schedule M—Bequests, etc., to Surviving Spouse (Marital Deduction) of the decedent spouse’s IRS Form 706 (the federal estate tax return) to allocate it to the marital share instead.

An advantage of the Clayton election, in contrast to the disclaimer option, is that its technical requirements and timelines are less rigid. A disclaimer must be made within nine months after the first spouse’s death, while a Form 706 is not due until up to fifteen months (or possibly twenty-four months) after the first spouse’s death, allowing more time to grieve and for making a less emotion-driven decision. Another advantage of the Clayton election is that it allows someone other than the surviving spouse to objectively decide what property should be apportioned to the marital and nonmarital shares. In addition, because a Form 706 must be filed when using the Clayton election option, there is the opportunity to claim for future use any unused amount of the decedent spouse’s estate tax exemption. Finally, because the Clayton election sends the decedent spouse’s property into a nonmarital share trust by default, the surviving spouse automatically receives those accounts and property in a form that offers some degree of creditor protection.

Whether to use a marital formula in your estate plan, and which marital formula to use, requires considerable analysis of your estate, your goals, and the law.
