02 Estate Tax
The federal estate tax is a tax on the transfer of property at death, assessed on the total value of everything a person owns or has certain legal interests in at the time they die — real estate, bank accounts, investment portfolios, business interests, retirement accounts, and life insurance proceeds the decedent controlled. It is paid by the estate itself, out of estate assets, before anything is distributed to heirs, which is an important distinction from an inheritance tax, which is paid by the people who receive the property.
Despite its reputation, the federal estate tax touches only a small fraction of American households. Thanks to a large lifetime exemption — currently in the millions of dollars per person — the vast majority of estates owe no federal estate tax at all. The tax applies only to the value of an estate that exceeds the exemption amount, and the IRS form used to report it, Form 706, is required only when the gross estate plus prior taxable gifts surpasses that filing threshold.
Some individual states layer an additional state-level estate tax on top of the federal one, often with exemption amounts far lower than the federal threshold — meaning an estate that owes nothing to the IRS could still owe tax to a state government. As of the current tax year, a minority of states impose their own estate tax, so where a decedent was domiciled can materially change the total tax bill.
03 Inheritance Tax
Inheritance tax is frequently confused with estate tax, but the two are structurally different. While the estate tax is levied on the estate before distribution, an inheritance tax is levied on the individual beneficiary after they receive their share, and the rate they pay typically depends on their relationship to the deceased. There is no federal inheritance tax in the United States; inheritance tax exists only at the state level, and only a handful of states currently impose one.
In states that do levy an inheritance tax, spouses are almost always fully exempt, children and grandchildren typically face the lowest tax rates or generous exemptions, and more distant relatives or unrelated beneficiaries — such as friends or domestic partners not legally married — usually face the highest rates. Because both the size of the bequest and the recipient's relationship to the decedent factor into the calculation, two people inheriting the same dollar amount from the same estate can end up with very different tax bills.
Estate Tax vs. Inheritance Tax at a Glance
| Feature | Estate Tax | Inheritance Tax |
|---|---|---|
| Who pays | The estate itself | The individual beneficiary |
| When assessed | Before distribution | After distribution |
| Levied by | Federal government (some states) | State government only |
| Rate depends on | Size of the estate | Size of bequest and relationship to decedent |
| Spousal treatment | Generally unlimited deduction | Generally fully exempt |
It is possible, though uncommon, for a single estate to be subject to federal estate tax, a separate state estate tax, and an inheritance tax owed by a beneficiary, if the decedent lived in a state that imposes both and left assets to relatives outside the typically exempt categories.
04 Determining Taxable Value of an Estate
Calculating the taxable value of an estate starts with the gross estate: the fair market value, as of the date of death, of everything the decedent owned or controlled. This includes real property, brokerage and bank accounts, closely held business interests, retirement accounts such as IRAs and 401(k)s, vehicles, art and collectibles, and — importantly — the full death-benefit value of any life insurance policy the decedent owned on their own life, even though the proceeds pass directly to a named beneficiary outside of probate.
From that gross estate figure, the IRS allows a series of deductions to arrive at the taxable estate:
Debts and funeral expenses — outstanding mortgages, personal loans, credit card balances, and the reasonable costs of the funeral and estate administration, including legal and executor fees, are all subtracted.
The marital deduction — any assets passing outright to a surviving spouse who is a U.S. citizen are generally deducted from the estate in full, regardless of amount, deferring any estate tax until the second spouse's death.
The charitable deduction — the value of any bequest to a qualifying charitable organization is fully deductible.
The result is the taxable estate. Because the federal exemption is "unified" across both lifetime gifts and the estate at death, any taxable gifts made during life beyond the annual exclusion are added back to the taxable estate for purposes of calculating how much of the lifetime exemption remains available — which is exactly the calculation the tool above performs.
05 Reducing Estate Tax
Because the estate tax applies only above a high exemption threshold and at a flat top rate on the excess, most estate tax planning focuses on legally moving value out of the taxable estate well before death, or structuring it so less of it counts against the exemption. Common techniques include:
Lifetime gifting. Systematically gifting assets during life, using the annual gift tax exclusion and, where appropriate, larger gifts that draw down the lifetime exemption while the assets — and any future appreciation — are removed from the taxable estate.
Irrevocable trusts. Vehicles such as irrevocable life insurance trusts (ILITs), grantor retained annuity trusts (GRATs), and qualified personal residence trusts (QPRTs) can move specific assets, and their future growth, outside the taxable estate while still providing benefits to the grantor's family.
Spousal portability. A surviving spouse can elect to use any unused portion of a deceased spouse's federal exemption, effectively allowing a married couple to shield roughly double the individual exemption amount without complex trust planning, provided a timely estate tax return is filed.
Charitable giving. Charitable trusts and direct bequests reduce the taxable estate dollar-for-dollar while supporting causes the decedent cares about.
Family business and valuation discounts. Interests in family limited partnerships or closely held businesses may, under certain conditions, be valued at a discount for lack of marketability or minority control, reducing the reported value included in the estate.
The most effective estate tax reduction strategies are put in place years, sometimes decades, before death — waiting until a terminal diagnosis sharply limits what can legally be done.
06 Annual Gift Tax Exclusion
The annual gift tax exclusion allows any individual to give up to a set dollar amount, per recipient, per year, completely free of gift tax and without using any of their lifetime exemption. The amount is indexed for inflation and adjusted periodically by the IRS. Because the exclusion applies per recipient, a parent can give the annual exclusion amount to each of several children, and — if married — both spouses can combine their exclusions through "gift splitting" to effectively double the amount that can move tax-free to a single recipient each year.
Gifts that exceed the annual exclusion in a given year to a single recipient are not necessarily taxed immediately; instead, the excess is reported on a gift tax return and counts against the giver's lifetime unified exemption, the same pool of exemption used at death. Only once a person's cumulative lifetime gifts exceed the full exemption amount does actual gift tax become payable. Certain payments are excluded from the gift tax calculation entirely regardless of size, most notably tuition paid directly to an educational institution and medical expenses paid directly to a healthcare provider on someone else's behalf.
Used consistently over many years, the annual exclusion can move a substantial amount of wealth out of a taxable estate with no tax cost and no paperwork beyond simple recordkeeping, which is why it remains one of the most widely used estate-reduction tools available to ordinary families, not just the ultra-wealthy.
07 Estate Planning
Estate planning is the broader process of arranging how a person's assets will be managed during incapacity and distributed after death, and minimizing estate tax is only one piece of that picture. A complete estate plan typically includes a will or revocable living trust to direct how assets are distributed and to name guardians for minor children; a durable power of attorney to authorize someone to manage financial affairs if the person becomes incapacitated; and an advance healthcare directive or living will to document medical wishes.
Beneficiary designations on retirement accounts and life insurance policies pass outside of a will entirely, so keeping these designations current is one of the simplest and most overlooked estate planning steps. For larger or more complex estates, trusts can help assets avoid the time and cost of probate, provide for beneficiaries with special needs without disqualifying them from government benefits, and protect assets from creditors or remarriage in blended families.
Because tax law, exemption amounts, and family circumstances all change over time, estate plans are not a one-time exercise. Most estate planning attorneys recommend reviewing a plan every few years, and immediately after major life events such as marriage, divorce, the birth of a child, a significant change in net worth, or a move to a new state with different estate or inheritance tax rules. The calculator on this page can help illustrate the potential federal tax exposure of an estate, but a qualified estate planning attorney and tax advisor should always be part of putting any of these strategies into practice.
