Why estate tax myths persist
Estate taxes generate more confusion than almost any other area of tax law. Part of the problem is that the rules change with legislation, vary by state, and intersect with gift tax, income tax, and trust law in ways that are genuinely hard to track. The result is that many retirees make consequential assumptions, either dreading a tax bill their estate will never face, or ignoring real exposure because they assume the rules do not apply to them.
Getting this right matters. Poor assumptions lead to inadequate planning, which can mean unnecessary taxes, probate costs, and family disputes. The myths below are the ones most likely to cost heirs money when left uncorrected. For a grounding in the fundamentals before working through these corrections, see the estate planning fundamentals guide covering wills, beneficiary designations, and core documents.
Myth
Most people will owe federal estate tax when they die, so everyone needs aggressive tax shelter strategies.
Fact
The federal estate tax applies to a very small percentage of estates. The exemption amount is set by Congress and has been above $10 million per individual (adjusted for inflation) since 2018, meaning the vast majority of Americans owe nothing at the federal level.
The federal estate tax is a tax on the transfer of wealth from a deceased person to their heirs when the taxable estate exceeds a legislatively set threshold. For deaths occurring in 2024, the exemption is $13.61 million per individual, or $27.22 million for a married couple using portability (the ability of a surviving spouse to use the deceased spouse's unused exemption).
According to IRS Statistics of Income data, fewer than 1 in 1,000 estates actually owe federal estate tax in a given year. The concern is understandable given how often the term appears in financial media, but for most retirees, federal estate tax is not a threat to their heirs. The more relevant issues are often income tax on inherited retirement accounts, state-level estate taxes, and probate costs. Those planning concerns require attention even when the federal estate tax does not.
Myth
If my estate is under the federal exemption, my heirs will owe no estate or inheritance tax at all.
Fact
Many states impose their own estate or inheritance taxes with exemptions far below the federal level. Heirs in those states may owe significant state taxes even when no federal estate tax applies.
As of 2024, a dozen states and the District of Columbia levy a state estate tax, and six states impose an inheritance tax (which is paid by the heir, not the estate). Some states have exemptions as low as $1 million, meaning a retiree with a modest home, retirement accounts, and a life insurance policy could easily trigger state-level tax even if the federal threshold is untouched.
Oregon, Massachusetts, and Washington, for example, each impose estate taxes at rates reaching 16% or higher on estates above their state-specific thresholds. Maryland is unique in imposing both an estate tax and an inheritance tax. Retirees in these states, or those who own property there, should factor state exposure into planning rather than relying solely on the federal picture. This is one area where assumptions about asset location can compound an estate planning problem.
Myth
Leaving everything to my spouse eliminates estate tax concerns for our combined estate.
Fact
The marital deduction defers federal estate tax on assets passing to a surviving US citizen spouse, but it does not eliminate the eventual tax exposure on a combined estate above the applicable exemption.
The unlimited marital deduction is a powerful tool: assets transferred to a surviving US citizen spouse at death are generally excluded from the deceased spouse's taxable estate. This means a couple can often pass the entire estate to the survivor without any immediate federal estate tax. However, the survivor then holds a larger estate, and if its value exceeds the available exemption at the survivor's death, the excess is taxable.
The solution available under current law is portability, which allows a surviving spouse to elect to use the deceased spouse's unused exemption by filing a federal estate tax return (Form 706) within nine months of the first death, with a possible extension to 15 months. Without that election, the unused exemption is lost. Couples with larger estates may also use credit shelter trusts (also called bypass trusts) as an alternative strategy. The right approach depends on the size of the combined estate, state law, and future legislative risk around the exemption amount. Consulting an estate attorney before the first spouse's death preserves the most options.
Myth
Heirs who inherit appreciated stock or real estate will owe capital gains tax on the full gain from the original purchase price.
Fact
Inherited assets generally receive a stepped-up cost basis equal to the fair market value at the date of the decedent's death, eliminating the capital gains tax on appreciation that occurred during the original owner's lifetime.
The stepped-up basis rule under IRC Section 1014 is one of the most financially significant provisions in estate law. If a parent purchased stock for $50,000 decades ago and it is worth $500,000 at death, the heir's cost basis becomes $500,000. A sale shortly after inheritance triggers little or no capital gains tax. The $450,000 of gain that built up over the parent's lifetime is permanently excluded from income tax.
This rule has direct implications for planning. Assets with large unrealized gains are often better candidates to hold until death rather than gifting during life, where the donor's original cost basis transfers to the recipient. Gifts made during life carry the donor's basis, so the recipient inherits the full embedded gain. Conversely, assets already at a loss may be better candidates for lifetime gifting or sale, since a stepped-down basis is possible for inherited assets at a loss. The interaction between basis rules and broader tax planning is worth understanding before making large transfers in either direction.
Myth
Life insurance proceeds are never subject to estate tax because they pass directly to beneficiaries.
Fact
Life insurance death benefits are included in the taxable estate if the deceased owned the policy or held certain rights over it, regardless of who receives the proceeds.
Under IRC Section 2042, life insurance proceeds are included in the insured's gross estate if the insured held any incidents of ownership in the policy at death. Incidents of ownership include the right to change beneficiaries, borrow against the policy, or surrender the policy for cash value. Many retirees assume that naming a family member as beneficiary removes the policy from the estate; it does not, if they still own the policy.
One common solution is an irrevocable life insurance trust (ILIT). When an ILIT owns the policy, and the insured transfers no incidents of ownership, the death benefit can pass outside the taxable estate. There are specific rules: transfers of an existing policy into an ILIT trigger a three-year lookback period under IRC Section 2035, during which the proceeds remain estate-includable if the insured dies. New policies purchased directly by the trust avoid this issue. Because ILITs are irrevocable, the decision to establish one deserves careful legal review.
What these corrections mean for your planning
Correcting these misconceptions is not the endpoint; it is where productive planning begins. A few practical steps follow from the facts above.
First, calculate your actual taxable estate. Add up all assets you own or control: real property, retirement accounts, brokerage accounts, business interests, and life insurance death benefits if the policy is owned in your name. Compare that figure to both the federal exemption and your state's threshold. Many people are surprised to find that life insurance alone pushes them into state estate tax territory even when the federal exemption provides full cover.
Second, review account titling and beneficiary designations. Assets with named beneficiaries, such as IRAs and 401(k)s, pass outside a will but still count toward a taxable estate. Outdated designations can send assets to unintended recipients or into a probate estate unnecessarily.
Third, understand that annual gifts reduce the taxable estate over time. The annual gift tax exclusion allows transfers up to a set dollar amount per recipient per year without using any lifetime exemption. Consistent gifting over a decade can move meaningful wealth to heirs before death.
Outdated plans can create avoidable costs
Estate plans drafted before the 2017 Tax Cuts and Jobs Act may contain formula clauses tied to the old exemption amounts, which could produce unintended distributions or tax results under current law. Similarly, plans that predate significant asset growth, a marriage, a divorce, or the birth of additional heirs often reflect circumstances that no longer exist. A review every three to five years, or after any major life event, is a reasonable minimum. Estate law changes at the state level can also invalidate or reduce the effectiveness of documents that were valid when originally signed.
The interaction between estate taxes and income taxes on inherited assets is one area where tax-efficient planning pays off most. Decisions about which assets to give during life versus at death, and whether to use trusts or direct transfers, carry real dollar consequences that a qualified estate attorney and CPA can quantify for your specific situation.
