Passing wealth to the next generation is a tax-and-paperwork problem as much as a family one, and the pieces that quietly cost families the most are rarely the ones they worry about. For 2026, the federal estate tax exemption is $15 million per person, so most households will owe no federal estate tax at all.1Office of the Law Revision Counsel. 26 U.S. Code 2010 – Unified Credit Against Estate Tax What does catch people: state estate and inheritance taxes with much lower thresholds, income tax on inherited retirement accounts, probate delays, and missed deadlines that permanently erase valuable tax benefits. Effective intergenerational wealth transfer means choosing the right legal instruments, using the exemptions and deductions the code offers, and timing distributions so the family keeps as much as possible.
How Wealth Actually Moves at Death
Different assets move to heirs through different channels, and the channel usually matters more than the will.
Wills
A will names an executor and directs who gets what. It only takes effect at death and has to clear probate, the court-supervised process that validates the document and authorizes the executor to act. Execution rules vary by state, but most require signing in front of at least two disinterested witnesses.
Die without one, and state intestacy law decides. Those default rules follow a rigid hierarchy: spouse first, then children, then more distant relatives. Blended families and unmarried partners tend to get the worst outcomes.
Revocable and Irrevocable Trusts
A revocable living trust holds assets in a separate legal entity while you keep full control during your lifetime. You can amend it, move property in and out, or dissolve it entirely. At death, assets held in the trust pass directly to the named beneficiaries without going through probate, which saves time and keeps the details out of the public record.2Consumer Financial Protection Bureau. What Is a Revocable Living Trust?
An irrevocable trust is a different animal. Once you fund it, you give up ownership and control for good. In exchange, the assets are excluded from your taxable estate, which is why irrevocable trusts are a workhorse for families whose wealth exceeds the federal exemption.
Beneficiary Designations
Retirement accounts, life insurance policies, and many bank and brokerage accounts let you name a beneficiary directly on the account. Those assets transfer immediately at death without touching probate, and they override whatever the will says. Banks use “payable on death” registrations; brokerages use “transfer on death.” An outdated form naming an ex-spouse will beat a carefully drafted will every time, so review these after any major life event.
Small Estate Shortcuts
Most states offer a simplified procedure for smaller estates. Heirs file an affidavit confirming the estate falls under a state-set value threshold, wait out a state-specific period after death, and skip formal probate. Where the estate qualifies, this cuts months of court time and significant legal fees.
What the Federal Government Taxes
Federal law taxes large wealth transfers through three connected systems: the estate tax, the gift tax, and the generation-skipping transfer tax. All three share a single lifetime exemption of $15 million per person for 2026, set by the One, Big, Beautiful Bill Act signed into law on August 4, 2025.1Office of the Law Revision Counsel. 26 U.S. Code 2010 – Unified Credit Against Estate Tax The exemption adjusts annually for inflation after 2026.
Estate Tax
The estate tax applies to the total value of the deceased’s property, including real estate, investments, business interests, and personal property.3Office of the Law Revision Counsel. 26 U.S. Code 2001 – Imposition and Rate of Tax Only the amount above the $15 million exemption is taxed, and the top rate is 40%. The executor must file IRS Form 706 within nine months of the date of death if the gross estate plus prior taxable gifts exceeds the exemption.4Office of the Law Revision Counsel. 26 U.S. Code 6075 – Time for Filing Estate and Gift Tax Returns A six-month filing extension is available through Form 4768, but it does not extend the payment deadline; interest and penalties accrue on any unpaid tax after the nine-month mark.5eCFR. 26 CFR 20.6081-1 – Extension of Time for Filing the Return
Gift Tax
The gift tax reaches lifetime transfers. For 2026, each donor can give up to $19,000 per recipient per year without filing anything or touching the lifetime exemption.6Internal Revenue Service. What’s New – Estate and Gift Tax A married couple can combine their exclusions to give $38,000 per recipient. Amounts above the annual exclusion require filing IRS Form 709 and reduce the donor’s remaining lifetime exemption dollar for dollar.7Office of the Law Revision Counsel. 26 U.S. Code 2503 – Taxable Gifts
Systematic annual gifting is one of the more accessible ways to move wealth out of a taxable estate. A couple with three children and six grandchildren can move $342,000 out of the estate every year with no tax and no paperwork.
Generation-Skipping Transfer Tax
The generation-skipping transfer (GST) tax stops families from dodging estate tax by leaving assets directly to grandchildren or later generations. It applies to transfers to anyone two or more generations below the transferor, whether the transfer is outright or through a trust benefiting multiple generations.8Office of the Law Revision Counsel. 26 U.S. Code 2601 – Tax Imposed The GST exemption matches the estate tax exemption at $15 million for 2026, and the rate above the exemption is 40%. Willful evasion of any transfer tax obligation is a felony carrying up to five years in prison and fines up to $100,000.9Office of the Law Revision Counsel. 26 U.S. Code 7201 – Attempt to Evade or Defeat Tax
State Estate and Inheritance Taxes
The federal number is not the whole story. About 17 states and the District of Columbia impose their own estate or inheritance taxes, and their thresholds often start far below the federal line. Some begin taxing estates at $1 million or $2 million.
The two tax types work differently. An estate tax is paid by the estate before distributions go out. An inheritance tax is paid by each beneficiary based on what they receive and their relationship to the deceased. Spouses and children typically get exemptions or lower rates; distant relatives and unrelated beneficiaries pay the most. A few states impose both, requiring separate filings calculated independently from the federal return.
Spousal Transfers and Portability
Transfers between spouses get the best treatment in the code. The unlimited marital deduction lets you leave any amount of property to a surviving spouse with no federal estate or gift tax, provided that spouse is a U.S. citizen.10Office of the Law Revision Counsel. 26 U.S. Code 2056 – Bequests, Etc., to Surviving Spouse The property generally has to pass outright, though certain trusts like qualified terminable interest property (QTIP) trusts also qualify.11Internal Revenue Service. Frequently Asked Questions on Estate Taxes
The marital deduction delays tax; it does not erase it. When the surviving spouse dies, whatever remains is taxed against their own exemption. Portability is the fix. The executor of the first spouse’s estate can elect to transfer any unused portion of that spouse’s $15 million exemption to the survivor. If the first spouse used $3 million, the survivor picks up the other $12 million and adds it to their own $15 million, for a combined shield of $27 million.1Office of the Law Revision Counsel. 26 U.S. Code 2010 – Unified Credit Against Estate Tax
Portability is not automatic. It requires filing Form 706 for the first spouse’s estate even when no tax is owed. The return must be filed within nine months of death (plus the six-month extension if requested), or within five years under a special relief procedure for estates not otherwise required to file.12Internal Revenue Service. Instructions for Form 706 Miss the deadline and the unused exemption is gone. This is where families without professional guidance quietly lose millions in future tax protection, because there is no obvious reason to file an estate tax return when no tax is owed.
The Step-Up in Basis
One of the most valuable benefits of transferring wealth at death has nothing to do with the estate tax. When you inherit property, your cost basis for capital gains purposes resets to the asset’s fair market value on the date of death.13Office of the Law Revision Counsel. 26 U.S. Code 1014 – Basis of Property Acquired From a Decedent If a parent bought stock for $50,000 that was worth $500,000 at death, the heir’s basis is $500,000. Sell the next day for $500,000 and the capital gains tax is zero. The $450,000 of appreciation is permanently erased.
Step-up applies to real estate, stocks, business interests, and essentially any capital asset passing through an estate. It does not apply to lifetime gifts. A gifted asset carries the donor’s original basis, which is why families often hold appreciated property until death rather than gifting it early.
Married couples in community property states get more. When one spouse dies, both halves of community property step up to fair market value, not just the deceased spouse’s half.14Internal Revenue Service. Publication 555 – Community Property In common-law states, only the decedent’s share of jointly held property gets the step-up. The gap can be worth hundreds of thousands of dollars.
Income Tax on Inherited Retirement Accounts
Most inherited assets arrive free of income tax. Retirement accounts are the big exception. Traditional IRAs and 401(k)s were funded with pre-tax dollars, so every distribution is taxable income to the person who receives it, and the timing rules depend on the beneficiary’s relationship to the deceased.
Non-spouse beneficiaries who inherited from someone who died after 2019 have to empty the account by the end of the tenth year following the account owner’s death.15Internal Revenue Service. Retirement Topics – Beneficiary Timing within that decade is flexible, but the account must be zero by the deadline. For large inherited IRAs, bunching withdrawals into a few years can push a beneficiary into much higher tax brackets.
A narrow group of “eligible designated beneficiaries” can still stretch distributions over their own life expectancy. That group includes:
- Surviving spouses, who can also roll the inherited IRA into their own account
- Minor children of the account owner, though the 10-year clock starts when they reach the age of majority
- Disabled or chronically ill individuals
- Beneficiaries no more than 10 years younger than the deceased account owner
Inherited Roth IRAs follow the same 10-year withdrawal timeline for non-spouse beneficiaries, but because Roth distributions are generally tax-free, the income tax sting is much smaller. As retirement accounts grow into a larger share of most family wealth, planning around the 10-year rule matters more each year.
Probate, and Why Assets Bypass It When They Can
Probate begins when the executor files the will with the local court. The court validates the will, appoints the executor, and issues documentation (often called letters testamentary) giving the executor authority to access accounts, sell property, and manage estate affairs. From there, the executor inventories assets, notifies creditors, pays debts and taxes, and distributes what remains.
Simple estates often clear probate in six to twelve months. Contested wills, complex assets, or tax disputes can stretch it to two years or more. Total costs, including attorney fees, executor compensation, and court fees, typically run between 4% and 7% of the estate’s value. That expense, plus the public nature of the process, is why revocable trusts and beneficiary designations are so widely used. Every asset that passes outside probate is one less asset the executor manages, the court oversees, and the family waits on.
Personal Liability for Executors and Trustees
Anyone agreeing to serve as executor or trustee needs to know what they’re taking on. Federal law gives the government priority over most other creditors when an estate cannot pay all its debts.16Office of the Law Revision Counsel. 31 U.S. Code 3713 – Priority of Government Claims A fiduciary who distributes assets to beneficiaries or pays unsecured creditors before settling federal tax obligations can be held personally liable for the shortfall if the estate later cannot cover what it owes the IRS.
Bad intent is not required. An executor who releases a large bequest early, then finds out the estate owes more in taxes than the remaining assets can cover, is on the hook personally. Funeral costs, reasonable administrative expenses, and secured debts can be paid ahead of federal claims without triggering liability. Unsecured medical bills, state taxes, and distributions to beneficiaries all create exposure if paid before the IRS is satisfied.
The practical rule: do not distribute anything to beneficiaries until the estate’s total tax liability is clear and there are enough assets reserved to cover it. Waiting for formal tax clearance from the IRS before final distributions adds time, but it is the safest way to close out a role that otherwise puts personal assets at risk.
