Your gross estate is the total fair market value of everything you owned or held certain interests in on the day you died, and it is the number the IRS starts with to decide whether federal estate tax is owed. For deaths in 2026, estates above $15,000,000 must file Form 706 and may owe tax at rates up to 40% on the amount over that threshold.1Internal Revenue Service. What’s New – Estate and Gift Tax The gross estate reaches further than most people expect. It sweeps in life insurance proceeds, joint accounts, certain gifts you already made, and trust property alongside the bank accounts, houses, and investments you would naturally list.
What Counts as Part of the Gross Estate
The statute starts wide. Everything a decedent held an interest in at death goes into the gross estate.2Office of the Law Revision Counsel. 26 U.S. Code 2033 – Property in Which the Decedent Had an Interest Vehicles, jewelry, art, and household goods count. So does real estate anywhere in the world, whether a primary home, a rental, or raw land.
Intangible property fills out the picture: cash, certificates of deposit, stocks, bonds, mutual funds, and cryptocurrency. Business interests come in too, including closely held shares, partnership stakes, and LLC memberships, no matter how hard they would be to sell quickly. If it had monetary value and the decedent owned an interest, it belongs in the gross estate.
Life Insurance
Proceeds payable to the estate are always included. Proceeds paid directly to a named beneficiary are also included when the decedent still held any “incidents of ownership” in the policy at death.3Office of the Law Revision Counsel. 26 U.S. Code 2042 – Proceeds of Life Insurance Those incidents include the right to change beneficiaries, borrow against the policy, cancel it, or assign it. A $2 million policy paid to a child gets counted in full if the parent kept any of those rights. Keeping the proceeds out generally requires transferring ownership, often to an irrevocable life insurance trust, and giving up all such rights more than three years before death.
Jointly Held Property
Property held in joint tenancy with right of survivorship also enters the gross estate. For non-spouse joint owners, the default rule includes the full value unless the survivor can prove they contributed their own money toward the purchase.4Office of the Law Revision Counsel. 26 U.S. Code 2040 – Joint Interests A parent who adds an adult child to a brokerage account can end up with the entire balance taxed in their estate. Only the portion the survivor actually paid for is excluded, and the survivor carries the burden of proof.
Spouses get a cleaner rule. When a married couple holds property as joint tenants or tenants by the entirety, exactly half the value is included in the first spouse’s gross estate no matter who paid for it.4Office of the Law Revision Counsel. 26 U.S. Code 2040 – Joint Interests
Property Given Away With Strings Attached
A transfer made during life can be pulled back into the gross estate when the decedent kept meaningful control. Deeding a house to a child while continuing to live in it rent-free is the textbook case. When the decedent retained the right to use, possess, or receive income from transferred property for life, the full value is included at death.5Office of the Law Revision Counsel. 26 U.S. Code 2036 – Transfers With Retained Life Estate The same rule applies when the decedent kept the power to decide who would enjoy the property or its income.
General Powers of Appointment
A person who held a general power of appointment over trust assets has those assets included in their gross estate, even when someone else created the trust. A general power exists when the holder can direct the property to themselves, their estate, their creditors, or the creditors of their estate.6Office of the Law Revision Counsel. 26 U.S. Code 2041 – Powers of Appointment Powers limited by an ascertainable standard tied to health, education, support, or maintenance do not count. A trust that lets a beneficiary withdraw funds “for any reason” creates inclusion; one limited to “health and support” does not.
Gifts Made Within Three Years of Death
Certain gifts made in the three years before death are added back to the gross estate. This applies to transfers that would have been included had the decedent kept them, such as a life insurance policy given away shortly before death.7Office of the Law Revision Counsel. 26 U.S. Code 2035 – Adjustments for Certain Gifts Made Within 3 Years of Decedent’s Death Any gift tax actually paid on gifts made within that three-year window also gets added back, so the estate does not benefit twice from a deathbed transfer. Ordinary cash gifts to children generally are not clawed back, and bona fide sales for full value are exempt.
Gross Estate vs. Probate Estate
These two terms describe different slices of the same financial picture, and confusing them causes real problems. The probate estate covers only assets that need a court-supervised process to transfer, usually property titled solely in the decedent’s name with no beneficiary designation. The gross estate is a tax concept that includes probate property plus life insurance, joint accounts, retirement accounts with named beneficiaries, and the trust and retained-interest property described above.
A carefully planned estate can have almost nothing in probate and still carry a multimillion-dollar gross estate. A low probate value does not mean the family can skip the federal return.
How Estate Assets Are Valued
Every asset in the gross estate must be assigned a fair market value, which the IRS defines as the price a willing buyer would pay a willing seller when neither is under pressure and both know the relevant facts.8Internal Revenue Service. Publication 561 – Determining the Value of Donated Property The default measurement date is the date of death. Closely held businesses, commercial real estate, and collectibles usually need professional appraisals, and the IRS can challenge any figure that lacks credible support.
Alternate Valuation Date
An executor can elect to value the entire estate as of six months after death instead of the date of death. The election is available only when it both decreases the total gross estate value and decreases the combined estate and generation-skipping transfer tax liability.9Office of the Law Revision Counsel. 26 U.S. Code 2032 – Alternate Valuation It applies to the whole estate, not selected assets, and once made it is irrevocable. Any asset sold or distributed during the six-month window is valued at the date of disposition rather than the six-month mark.
Special Use Valuation for Farms and Businesses
Families that own working farms or active business real estate can elect to value that property based on its current use rather than its highest and best use, which typically produces a lower number when developers would pay more for the land than a farmer would.10Office of the Law Revision Counsel. 26 U.S. Code 2032A – Valuation of Certain Farm, Etc., Real Property The reduction is capped at an inflation-adjusted amount (the base figure is $750,000, and the cap has exceeded $1,000,000 in recent years). Qualifying requires strict ownership, use, and material participation tests, and heirs must agree to a 10-year recapture rule if they later change how the property is used.
Why the Valuation Matters to Heirs
Estate valuation has a second consequence families often overlook. Property acquired from a decedent takes a new cost basis equal to its fair market value at death, or at the alternate valuation date if elected.11Office of the Law Revision Counsel. 26 U.S. Code 1014 – Basis of Property Acquired From a Decedent This “stepped-up basis” erases any unrealized capital gains that built up during the decedent’s life.
The impact can be substantial. A parent who bought stock for $50,000 that grew to $500,000 by the date of death passes it to heirs with a $500,000 basis. Selling immediately produces no capital gains tax; without the step-up, the heirs would owe tax on $450,000 of gain. An appraisal that undervalues inherited property lowers the heir’s basis and increases future capital gains exposure. Values reported on Form 706 become the starting point for income tax on any later sale.
From Gross Estate to Taxable Estate
The gross estate is not the amount that gets taxed. Several deductions narrow the gap between what’s counted and what’s actually taxed.12Office of the Law Revision Counsel. 26 U.S. Code 2051 – Definition of Taxable Estate
Debts and Administration Expenses
Funeral costs, executor commissions, attorney fees, and other expenses of settling the estate are deductible if they are allowable under the law of the jurisdiction administering the estate.13Office of the Law Revision Counsel. 26 U.S. Code 2053 – Expenses, Indebtedness, and Taxes Debts the decedent owed at death, including mortgages, credit card balances, medical bills, and personal loans, also reduce the taxable estate. A mortgage is deductible when the full property value (without subtracting the loan) is already in the gross estate, so nothing is counted twice.
Marital Deduction
Property passing to a surviving U.S. citizen spouse qualifies for an unlimited deduction. A $50 million estate can pass entirely to the surviving spouse with no federal estate tax at the first death.14Office of the Law Revision Counsel. 26 U.S. Code 2056 – Bequests, Etc., to Surviving Spouse The tax is deferred, not eliminated. Whatever remains when the surviving spouse dies goes into their own gross estate.
Charitable Deduction
Bequests to qualifying charities, religious organizations, government entities, and educational institutions reduce the taxable estate dollar for dollar with no cap.15Office of the Law Revision Counsel. 26 U.S. Code 2055 – Transfers for Public, Charitable, and Religious Uses A decedent who leaves the whole estate to charity owes no federal estate tax regardless of size.
State Death Taxes
Estates that pay state-level estate or inheritance taxes can deduct those payments on the federal return. Roughly 18 states and the District of Columbia impose their own death taxes, with exemption thresholds running from $1,000,000 to over $13,000,000. Many state thresholds sit well below the federal exemption, so an estate can owe state tax without owing federal tax.
The 2026 Exemption, the 40% Rate, and Portability
For deaths in 2026, the basic exclusion amount is $15,000,000 per individual.1Internal Revenue Service. What’s New – Estate and Gift Tax The exclusion was permanently raised by legislation signed in July 2025 and continues to adjust for inflation. A single person can pass up to $15 million without owing federal estate tax; a married couple who plans properly can pass $30 million.
Estates above the exclusion face a top marginal rate of 40%, applied only to the amount over the exclusion. A $16 million estate, after deductions, owes tax on roughly $1 million, not on the full $16 million.
When the first spouse dies without using all of their exemption, the surviving spouse can claim the unused portion through a portability election. The executor of the first spouse’s estate has to file Form 706 and compute the deceased spousal unused exclusion, even when no tax is due.16eCFR. 26 CFR 20.2010-2 – Portability Provisions Applicable to Estate of a Decedent Survived by a Spouse Skipping the return forfeits the election, which can cost the surviving spouse millions in future tax exposure. Executors of smaller estates who assume they do not need to file often miss this step.
Filing Deadline and Penalties
Form 706 is due nine months after the decedent’s date of death.17Office of the Law Revision Counsel. 26 U.S. Code 6075 – Time for Filing Estate and Gift Tax Returns An executor who needs more time can file Form 4768 for an automatic six-month extension, moving the filing deadline to 15 months after death.18eCFR. 26 CFR 20.6081-1 – Extension of Time for Filing the Return An extension of time to file is not an extension of time to pay. The estimated tax is still due at the original nine-month mark, and any shortfall accrues interest and penalties from that date.
Missing the deadline without an extension triggers a failure-to-file penalty of 5% of the unpaid tax for each month or partial month the return is late, capped at 25%.19Internal Revenue Service. Failure to File Penalty A separate failure-to-pay penalty of 0.5% per month runs at the same time and keeps accruing after the filing penalty caps out. On a $500,000 tax bill, filing penalties alone can reach $125,000 within five months, before interest and payment penalties are added.
