Exploring the Estate Tax

This is the first installment of a two-part article on the federal estate tax. Part 1 discusses the unified federal estate and gift tax rules, the exemption amount, the definition of a gross estate, gifts made within three yearof death, estate valuation, and portability. The second part, to appear in the November JofA, covers estate tax planning techniques, including maximizing the marital deduction and the use of various types of trusts.


A major area of personal financial planning is planning for the transfer of property during an individual’s lifetime and at death. Although most individuals do not have enough money to be concerned about federal gift and estate taxes, minimizing gift taxes and estate taxes is a primary financial goal for many millionaires and billionaires.

The federal estate and gift tax is referred to as a unified tax because both taxes use the same tax rate schedule and the same credit against the tax, called the unified credit. The unified credit amount in 2017 is $2,141,800, which is the tax on $5,490,000 of taxable value (the calculations in this article are based on 2017 figures). This $5,490,000 is called the basic exclusion amount.

An individual will be liable for the gift tax only if during the individual’s lifetime he or she transfers property by gift in excess of the basic exclusion amount. Because the basic exclusion amount applies to both the gift and estate tax, an individual’s estate will be liable for the estate tax only when the taxable value of the estate exceeds the individual’s exclusion amount, less the amount of taxable gifts the individual made during his or her lifetime.

The federal estate tax is owed by only about 1 out of 700 estates. It has gone through many changes since 2001 when estates with a taxable value of more than $675,000 were liable for the estate tax. This amount was increased gradually from $1 million in 2002—2003 to $5 million in 2010—2011. After 2011, the $5 million basic exclusion amount is adjusted for inflation; for 2017, it is $5.49 million.

This article discusses the mechanics of the estate tax as well as a number of planning techniques to minimize the federal estate tax so that the estate can transfer the maximum value to its beneficiaries. Although this discussion focuses on the federal estate tax and does not review state estate taxes, the relevant state rules must also be addressed as part of an individual’s financial plan.

Under Sec. 2001(a), the estate tax is imposed on the transfer of the taxable estate of every decedent who is either a citizen or a resident of the United States. The estate tax is calculated by adding together the decedent’s taxable estate (the gross estate less allowable deductions) and the decedent’s adjusted taxable gifts to determine the estate tax base (see below).

Formulas for calculating estate tax base and net estate tax liability

Gross estate – deductions = Taxable estate

Taxable estate + adjusted taxable gifts after 1976 = Estate tax base

Tentative estate tax – gift taxes paid after 1976 = Gross estate tax

Gross estate tax – unified credit – other credits = Net estate tax liability

Adjusted taxable gifts are taxable gifts made by the decedent after Dec. 31, 1976, other than gifts that are includible in the gross estate of the decedent. Next, the estate tax rates are applied to the estate tax base amount to determine the tentative estate tax. Gift taxes paid by the decedent after 1976 are then deducted from the tentative estate tax to arrive at the gross estate tax. Finally, the decedent’s remaining unified credit and any other credits are deducted from the gross estate tax to determine the decedent’s net estate tax liability.

Estates use Form 706, United States Estate (and Generation-Skipping Transfer) Tax Return, to calculate the estate tax liability of a decedent (this article does not address generation-skipping transfer (GST) taxes). Estates with a gross estate, plus adjusted taxable gifts, of more than the exclusion amount for the decedent’s year of death, and estates of any size whose executor elects to make a portability election, need to file an estate tax return, which is due within nine months after the date of the decedent’s death.


The gross estate includes all property, real or personal, tangible or intangible, wherever situated (Sec. 2031(a)). An estate lists property included in the gross estate on Form 706, Part 5, “Recapitulation,” lines 1—10.


The gross estate includes the proceeds of life insurance in two situations (Sec. 2042):

  • When the proceeds of life insurance are received by the estate as the beneficiary on a life insurance policy where the decedent is the insured; or
  • When the proceeds of life insurance are received by beneficiaries other than the estate on a life insurance policy where the decedent is the insured and possessed at the date of death any of the incidents of ownership.

Incidents of ownership include the right to change the beneficiary, the right to transfer ownership of the life insurance policy, and the right to use the policy’s value as collateral for a loan. An incident of ownership also includes a reversionary interest (whether arising under the policy or other instrument or by operation of law), but only if the reversionary interest’s value exceeded 5% of the policy’s value immediately before the decedent’s death (Sec. 2042(2)).

The gross estate also includes the replacement value of a life insurance policy owned by the decedent where someone other than the decedent is the insured.


The gross estate includes any interest in property (by trust or otherwise) transferred by the decedent during the three-yearperiod ending on the date of the decedent’s death if the property would have been included in the decedent’s estate if it had not been transferred (Sec. 2035(a)). In addition, any gift tax paid on these gifts is included in the gross estate (Sec. 2035(b)).


All property included in the gross estate is valued as of the date of the decedent’s death unless the executor elects the alternate valuation under Sec. 2032. If the executor elects the alternate valuation, the gross estate is valued as follows:

  1. For property distributed, sold, exchanged, or otherwise disposed of within six months after the decedent’s death, that property is valued as of the date of distribution, sale, exchange, or other distribution.
  2. Other property is valued as of the date six months after the decedent’s death.

The executor can elect the alternate valuation only if the gross estate and the sum of the estate tax on the estate and the GST tax on property included in the estate are less using the alternate valuation than the date-of-death valuation. The alternate valuation is calculated based on the aggregate value of the gross estate, not on an item-by-item basis. As a result, it is possible to use the alternate valuation even though one or more properties appreciate during the six-monthperiod between the date of death and the alternate valuation date.

The basis of property received by an estate’s beneficiary is either stepped-up (if the property has appreciated) or stepped-down (if the property has depreciated) to the fair market value (FMV) of the property at the date of the decedent’s death or, if elected, the value at the alternate valuation date (Sec. 1014). As a result, any pre-death (or pre-alternate valuation date) appreciation of property will escape income taxes. Consequently, as a general rule, highly appreciated property should not be sold before death. On the other hand, any pre-death (or pre-alternate valuation date) decrease in the value of property will not be available as a potential loss deduction to the beneficiary of the property. Thus, as a general rule, if possible, property that has lost value should be sold before death so that the decedent can realize the loss and potentially take an income tax deduction for it.


Estate tax deductions are reported on Form 706, Part 5, “Recapitulation,” lines 14—23. Deductions include:

  • Funeral expenses;
  • Expenses incurred in administering property subject to claims;
  • Debts of the decedent;
  • Mortgages and liens;
  • Net losses during settlement of the estate;
  • Expenses incurred in administering property not subject to claims;
  • Amounts passing to a surviving spouse; and
  • Charitable, public, and similar gifts and bequests.

Commissions paid to the estate’s executor are allowed as a deduction on the estate tax return. Likewise, attorneys’ fees and accounting fees paid are allowed as a deduction. In valuing the gross estate, the executor often needs an appraiser’s services, and the appraisal fees are allowed as a deduction. All debts the decedent owed as of the date of death are allowed as a deduction, including mortgages, automobile loans, student loan debt, and credit card debt.

As noted above, the estate can take a deduction for losses incurred during the estate settlement, including losses arising from fires, storms, shipwrecks, or other casualties or from theft (Sec. 2054). In a recent Tax Court case, the court showed a willingness to interpret the language in Sec. 2054 broadly to allow an estate a theft loss deduction where a limited liability company owned by the decedent lost money in a Ponzi scheme, diminishing its value to the estate (Estate of Heller, 147 T.C. No. 11 (2016)).

Since the estate can take a deduction for the decedent’s debts, any medical expenses owed at death can be deducted on the estate tax return. Medical expenses owed at death, in the alternative, could be deducted on the decedent’s final income tax return if the estate pays the medical expenses within one year of death (Sec. 213(c), Regs. Sec. 1.213-1(d)). The deduction on the estate return would more likely than not be more beneficial than taking the medical deduction on the decedent’s final income tax return because of the adjusted gross income limitation on the deductibility of medical expenses, which does not apply to estate tax returns. The executor has the flexibility of claiming all or part of the medical expenses owed at death on the decedent’s final income tax return rather than on the estate tax return.


In calculating the estate tax, married individuals are at a significant advantage over unmarried individuals since the estate of a decedent who was married at the time of death can take an unlimited estate tax deduction for all amounts passing to the surviving spouse (Sec. 2056(a)). Many married people have wills providing that all property passes to the surviving spouse. As a result, there is often no estate tax liability on the estate of the first spouse to die.


The taxable estate is the gross estate minus deductions. The estate tax is calculated on the estate tax base, which is the taxable estate plus adjusted taxable gifts after 1976. Once the estate tax base is known, the next step in the computation of the estate tax is to calculate a tentative estate tax on the estate tax base. Sec. 2001(c) contains the rate schedule that is used to calculate the tentative tax.
