Yes, non-probate assets are subject to federal estate tax. Life insurance proceeds, retirement accounts, jointly held property, and payable-on-death accounts all count toward the gross estate even though they skip probate entirely. The federal estate tax exemption for 2026 is $15,000,000 per individual, so most estates won’t actually owe anything, but every dollar of non-probate property pushes the total closer to that threshold.1Internal Revenue Service. What’s New – Estate and Gift Tax Above the exemption, the top rate is 40%.
Probate and Estate Tax Are Two Different Systems
Probate is a court process for distributing assets that don’t have a built-in transfer mechanism. A named beneficiary or a surviving co-owner takes non-probate assets automatically, so no court involvement is needed. The federal estate tax works on a separate track. It looks at everything the decedent owned or controlled at death, no matter how the property transfers afterward.2Office of the Law Revision Counsel. 26 U.S. Code 2033 – Property in Which the Decedent Had an Interest The tax applies to the taxable estate, meaning the gross estate minus allowable deductions.3Office of the Law Revision Counsel. 26 U.S. Code 2001 – Imposition and Rate of Tax Skipping probate is about convenience and privacy. It is not a way to skip the IRS.
How Each Type of Non-Probate Asset Is Included
Different non-probate assets are pulled into the gross estate under different provisions of the tax code, and the amount included isn’t always the full face value.
Life Insurance
Life insurance proceeds are included when the proceeds are payable to the estate itself, or when the decedent held any “incidents of ownership” in the policy at death.4Office of the Law Revision Counsel. 26 U.S. Code 2042 – Proceeds of Life Insurance Incidents of ownership is a broad concept. It covers the power to change beneficiaries, borrow against the policy, surrender or cancel it, or assign it to someone else. Even a reversionary interest worth more than 5% of the policy value counts. Hold a $2 million policy with any of those rights and the full $2 million lands in your gross estate.
Retirement Accounts
The full value of IRAs, 401(k)s, pensions, and other retirement accounts with named beneficiaries is included. The tax code treats these as annuities receivable by a beneficiary who survives the decedent, and employer contributions are treated as if the decedent made them.5Office of the Law Revision Counsel. 26 U.S. Code 2039 – Annuities A $1.5 million 401(k) enters the gross estate at $1.5 million, even though the beneficiary receives the funds outside probate.
Jointly Held Property
Property held in joint tenancy with right of survivorship or tenancy by the entirety passes automatically to the survivor. For estate tax, the general rule is that the full value goes into the first owner’s gross estate unless the survivor can prove they contributed to the purchase price.6Office of the Law Revision Counsel. 26 U.S. Code 2040 – Joint Interests
Spouses get an easier rule. When spouses hold property as joint tenants or tenants by the entirety, exactly half the value is included in the first spouse’s gross estate, regardless of who paid.6Office of the Law Revision Counsel. 26 U.S. Code 2040 – Joint Interests For non-spouse co-owners, such as a parent and adult child holding a house together, the estate has to document the child’s contribution to reduce the included amount.
Payable-on-Death and Transfer-on-Death Accounts
POD bank accounts and TOD investment accounts are included in the gross estate at full value on the date of death. The transfer is clean, but the decedent had unrestricted ownership up to the moment of death, so there is nothing to argue about.
Property With a Retained Life Estate
When someone transfers property but keeps the right to use it, live in it, or collect income from it for life, the full value remains in the gross estate. This comes up with transfer-on-death deeds for real estate, where the owner names a beneficiary but continues living in the home. The IRS treats the property as still belonging to the estate.
The Three-Year Rule on Life Insurance Transfers
Transferring ownership of an existing life insurance policy, often into an irrevocable trust, can remove the proceeds from the gross estate. It only works if the insured survives at least three years after the transfer. Die within that window and the full proceeds snap back into the gross estate as though the transfer never happened.7Office of the Law Revision Counsel. 26 U.S. Code 2035 – Adjustments for Certain Gifts Made Within 3 Years of Decedent’s Death One workaround is to have the trust apply for and purchase a brand-new policy from the start. If the insured never held ownership rights, there is no transfer to trigger the three-year clock.
Deductions That Can Erase the Tax
Inclusion in the gross estate does not automatically mean tax owed. Two deductions carry most of the weight.
The Marital Deduction
Assets passing to a surviving spouse who is a U.S. citizen are fully deductible from the gross estate, with no dollar cap.8Office of the Law Revision Counsel. 26 U.S. Code 2056 – Bequests, Etc., to Surviving Spouse This covers non-probate assets like jointly held property passing by survivorship and life insurance payable to the spouse. The deduction defers rather than eliminates tax. Those assets then sit in the surviving spouse’s gross estate, and any excess over the exemption at the second death gets taxed then. When the surviving spouse is not a U.S. citizen, the unlimited deduction doesn’t apply, and a Qualified Domestic Trust (QDOT) is typically used to defer the tax.
The Charitable Deduction
Assets left to qualified charities, religious organizations, educational institutions, or government entities are deductible with no cap.9Office of the Law Revision Counsel. 26 U.S. Code 2055 – Transfers for Public, Charitable, and Religious Uses Naming a charity as the beneficiary of a $3 million IRA still pulls that $3 million into the gross estate, but the matching deduction zeroes out the tax impact.
Portability Between Spouses
A married couple’s combined exemption is effectively $30,000,000 through portability. If the first spouse to die doesn’t use their full exemption, the survivor can add the unused portion to their own. It doesn’t happen on its own. The executor of the first estate must file Form 706 to elect it, even if that estate owes no tax.10Internal Revenue Service. Instructions for Form 706 Missing this election is one of the more expensive oversights in estate planning for high-net-worth couples.
Who Actually Pays the Tax on a Non-Probate Asset
The tax is assessed against the estate as a whole, but non-probate assets go straight to their named beneficiaries. Someone still has to pay. Who that is depends on whether the estate plan includes a tax apportionment clause.
Without such a clause, state law fills the gap. Most states use equitable apportionment, meaning each beneficiary pays the share of estate tax attributable to what they received. A child who receives a $500,000 life insurance payout could owe a proportional slice of the total estate tax bill, which is often an unwelcome surprise.
The estate plan can override this default. An apportionment clause in the will or trust can direct that all estate taxes be paid from the probate residuary, sparing non-probate beneficiaries, or it can spread the burden across everyone. Without clear direction, the executor may need to collect tax payments from life insurance beneficiaries and retirement account holders, which is a recipe for family conflict.
State Estate and Inheritance Taxes
The federal exemption is only part of the picture. Roughly a dozen states and the District of Columbia impose their own estate taxes, and several others tax the recipient through an inheritance tax. State exemption thresholds run well below the federal figure, with some starting as low as $1,000,000. An estate worth $5,000,000 might owe nothing to the IRS and still face a substantial state bill. Non-probate assets are generally included at the state level too, following the same logic as the federal rules.
Keeping Non-Probate Assets Out of the Gross Estate
With enough lead time, several tools can legitimately reduce or eliminate inclusion.
- Irrevocable life insurance trust (ILIT). When the trust, not the insured, owns and is the beneficiary of a policy, the proceeds aren’t included in the insured’s gross estate. The insured must never hold any incidents of ownership. For new policies, the trust should apply for the policy from the start; for existing policies transferred in, the insured must survive three years.4Office of the Law Revision Counsel. 26 U.S. Code 2042 – Proceeds of Life Insurance
- Spousal rollover of retirement accounts. A surviving spouse who inherits a retirement account and rolls it into their own IRA removes it from the deceased spouse’s estate. Combined with the marital deduction, this avoids immediate tax, though the account enters the survivor’s estate later.
- Charitable beneficiary designations. Naming a qualified charity as beneficiary of a retirement account removes it from the taxable estate through the charitable deduction, and the charity receives the funds free of income tax as well.9Office of the Law Revision Counsel. 26 U.S. Code 2055 – Transfers for Public, Charitable, and Religious Uses
- Lifetime gifting. Assets given away during life, within the annual exclusion or applied against the lifetime exemption, reduce the gross estate. Joint accounts can be restructured and beneficiary designations updated to reflect completed gifts.
None of these strategies work at the last minute. ILITs need the three-year window. Trust and beneficiary changes require coordination with the rest of the plan. Real planning for non-probate assets happens years before death, not weeks before.
