Estate Planning Basics

Estate planning is not about avoiding taxes. For 99.9% of American households there is no estate tax to avoid. It is about making sure the right people get the right things without a court, a lawyer, and eighteen months standing in the way.

What estate planning is actually for

Say the word "estate" and most people picture a mansion. In legal terms your estate is simply everything you own: the checking account, the car, the 401(k), the house, the photos on your phone. Everyone has one, and everyone's will eventually be distributed. The only question is whether it happens according to your instructions or according to a default statute written by your state legislature.

Estate planning answers four questions:

• Who gets what, and when.
• Who raises your minor children if you and the other parent are gone. For parents this dwarfs everything else on the list.
• Who makes decisions for you if you are alive but cannot decide for yourself. This is the part that gets used most often, and it applies at any age.
• How much friction, cost, and delay your survivors face at the worst moment of their lives.

Notice that only the first question involves money. Surveys consistently find that a majority of American adults have no will at all. Dying without one means dying intestate, and the state's intestacy statute takes over. Those statutes are not crazy, but they are blunt. In many states a surviving spouse does not receive everything: a portion goes to children, including minor children whose share must then be held in a court-supervised account until they turn 18 and receive it outright. Unmarried partners, stepchildren you raised, and close friends generally receive nothing at all, no matter how obvious your intentions were to everyone who knew you.

This guide is general education about how these instruments work, not legal or individualized financial advice. Estate law is state law and varies substantially. Anything beyond the simplest situation deserves an hour with an estate attorney licensed where you live, which typically costs less than people expect and far less than fixing an error posthumously.

The documents everyone needs

Five documents cover the overwhelming majority of adults. Not one of them is exotic.

1. A will. Names who receives your probate property, names an executor (also called a personal representative) to administer it, and, critically, nominates a guardian for minor children. If you have children under 18 and nothing else on this list, do the will for the guardianship clause alone. Without it, a judge who has never met your family chooses, potentially from among competing relatives.

2. A durable power of attorney for finances. Names someone to handle money matters if you are incapacitated: pay the mortgage, file taxes, manage accounts, deal with insurance. "Durable" means it survives your incapacity, which is the entire point. Without one, your family must petition a court for a conservatorship, which is slow, public, expensive, and ongoing.

3. A health care proxy or medical power of attorney. Names someone to make medical decisions when you cannot speak for yourself. Choose someone who can stay steady in a hospital corridor and who will follow your wishes rather than their own.

4. An advance directive or living will. States your wishes about life-sustaining treatment. Its real function is not legal so much as human: it removes an unbearable decision from the shoulders of someone who loves you.

5. A HIPAA authorization. Small, boring, and constantly overlooked. Without it, medical privacy law can prevent providers from even discussing your condition with your family. Many health care proxy forms include HIPAA language; confirm that yours does.

Two more worth adding if they apply to you: a letter of instruction (not legally binding, but it tells your executor where everything is, who to call, and what you want for a funeral), and for parents of young children a short standby guardian designation if your state offers one, so that someone can take custody immediately without waiting on a court.

On execution formalities: wills generally require your signature plus two witnesses, and many states allow a self-proving affidavit before a notary that spares your witnesses from having to testify later. Handwritten (holographic) wills are valid in some states and void in others. Online will services are legitimate for genuinely simple situations if you follow the signing instructions exactly; the most common failure with them is not the document but the execution.

Beneficiary designations beat your will

This is the single most important mechanical fact in the subject, and it surprises nearly everyone.

A beneficiary designation on an account overrides your will. Completely. Your will governs only probate property, meaning assets that pass through your estate. Assets with a named beneficiary skip probate entirely and go directly to the named person, regardless of what your will says, regardless of when the will was written, and regardless of what everybody knows you would have wanted.

Assets that pass by designation rather than by will:

• 401(k), 403(b), and other employer retirement plans
• Traditional and Roth IRAs
• Life insurance policies
• Annuities
• HSAs
• Bank accounts with a payable on death (POD) designation
• Brokerage accounts with a transfer on death (TOD) registration
• Property held in joint tenancy with right of survivorship

For most households under retirement age, that list covers the large majority of their net worth. The will governs the leftovers.

What to do, this month:

1. List every account on the list above.
2. Log in and read the current primary and contingent beneficiaries. Do not rely on memory.
3. Name a contingent (backup) beneficiary on every one. If the primary predeceases you and there is no contingent, the asset falls into probate and loses the fast, private transfer you were counting on.
4. Use percentages, not dollar amounts, so the split works regardless of the balance.
5. Do this again after every marriage, divorce, birth, death, or job change.

Two cautions. Naming a minor child directly as beneficiary is usually a mistake: a minor cannot hold an account, so a court appoints a guardian of the property, and at 18 the child receives the balance outright. Name a trust for the child's benefit, or a custodian under your state's transfers to minors act, instead. And naming your estate as beneficiary of a retirement account is generally the worst option available: it forces probate and accelerates the required payout of the account for income tax purposes.

One more rule specific to workplace plans: under federal law, a married participant's 401(k) generally must name the spouse as beneficiary unless the spouse consents in writing, usually notarized. IRAs have no such requirement, which is a meaningful difference when someone rolls a 401(k) into an IRA.

TOD, POD, and joint titling

These are the simplest probate-avoidance tools in existence and they are free.

POD (payable on death) applies to bank accounts and CDs. TOD (transfer on death) applies to brokerage accounts, and in a growing number of states to vehicles and even to real estate through a transfer on death deed. In every case you retain complete ownership and control while alive. The beneficiary has no rights, cannot see the account, and cannot touch it. On death, they present a death certificate and identification and the asset transfers, typically in days rather than months.

Joint tenancy with right of survivorship also avoids probate: the survivor simply owns the whole thing. It is convenient and it carries real drawbacks that get glossed over:

• The joint owner is an owner now. They can withdraw the money today.
• The asset is exposed to the joint owner's creditors, lawsuits, and divorce.
• Adding a non-spouse as joint owner can be a taxable gift.
• It can wreck a step-up in basis (see below) on half or more of the asset.
• It overrides your will, so adding one adult child as joint owner on a house to "make things easier" can accidentally disinherit the others.

The common well-meant error is an aging parent adding one child to a bank account for help with bills. The intended effect is convenience; the legal effect is that the child inherits the entire account. If convenience is the goal, use a power of attorney or an authorized signer arrangement, and use POD for the inheritance.

Probate in plain English

Probate is the court process that validates a will, appoints an executor, notifies creditors, settles debts and taxes, and authorizes distribution to heirs. Every state has a version. The reputation is worse than the reality in some states and fully deserved in others.

Typical costs and timelines:

Most states offer a small estate affidavit or summary procedure for estates below a threshold (commonly $50,000 to $200,000, though it varies widely), which is fast and cheap. And critically, the threshold usually counts only probate property, so if the house is in a trust or held jointly and everything else has a beneficiary designation, an estate that looks large on paper may qualify for the simple process or skip probate entirely.

One situation that reliably justifies planning around probate: real property in more than one state. Real estate is probated where it sits, so a house in one state and a cabin in another means two separate probate proceedings, called ancillary probate. Holding the out-of-state property in a revocable trust, or using a transfer on death deed where available, avoids the second one.

Trusts without the jargon

A trust is a legal container. Three roles define it: the grantor (who puts assets in), the trustee (who manages them under the trust's rules), and the beneficiary (who benefits). In the most common kind, one person plays all three roles while alive.

Revocable living trust. You create it, you are the trustee, you are the beneficiary, and you can change or cancel it any time. Legally the trust owns your assets; practically nothing about your life changes. You still use the accounts, still file the same tax return, still sell the house if you like. There is no tax benefit whatsoever: for income tax purposes it is you, and for estate tax purposes the assets are still in your estate.

What it does buy:

• Probate avoidance for everything titled into it, in every state where you own property.
• Privacy. A trust is not filed with a court, unlike a will.
• Incapacity management. Your named successor trustee steps in immediately without a court, which is often the most valuable feature.
• Control over timing. You can direct that a beneficiary receives money at 25, 30, and 35 rather than all at once at 18. This alone justifies a trust for many parents.

The catch, and it is the reason many trusts fail: the trust must be funded. Signing the document accomplishes nothing by itself. You have to retitle the house deed, the bank accounts, and the taxable brokerage accounts into the name of the trust. An unfunded trust is an expensive binder on a shelf, and its assets go through exactly the probate you paid to avoid. Note that retirement accounts are normally not retitled into a trust, because the transfer would be a taxable distribution; you use beneficiary designations for those instead.

Whether a revocable trust is worth it depends heavily on your state. In states with expensive statutory probate fees (California and Florida are the usual examples), a trust is close to standard practice for a homeowner. In states that have adopted streamlined probate codes, a plain will plus TOD and POD designations often achieves the same result for far less money.

Irrevocable trusts. Here you genuinely give the assets away to a separate legal entity and cannot take them back. That loss of control is the price of the benefits: the assets can be removed from your taxable estate, and they can be protected from your future creditors. These are specialist instruments used for estate tax reduction at high net worth, for Medicaid planning under strict lookback rules, for life insurance (an irrevocable life insurance trust keeps a death benefit out of the taxable estate), and for special needs planning where an inheritance would otherwise disqualify a disabled beneficiary from means-tested benefits. Do not attempt these from a template.

Two other terms you will meet:

Testamentary trust. A trust created by your will, springing into existence at death. Common for minor children: assets pass into a trust with a trustee who manages them until stated ages. It does not avoid probate, since the will still goes through it, but it solves the "18 year old receives $600,000 in cash" problem.

Spendthrift provision. Standard language preventing a beneficiary from pledging their interest and shielding it from their creditors. Nearly always worth including.

Step-up in basis, with the math

This is the most valuable tax provision most families will ever use, and it is entirely passive.

When you inherit an appreciated asset, its cost basis resets to the fair market value on the date of death. All the appreciation during the decedent's lifetime escapes capital gains tax permanently.

Worked example 1: gift versus inheritance. A parent bought a rental property in 1990 for $80,000. It is worth $600,000 today. There is $520,000 of unrealized gain.

The same asset, the same family, the same recipient. The difference is only timing, and it is worth six figures. This is why "give the house to the kids now to keep it out of probate" is so often a costly mistake: it trades a modest probate saving for a large capital gains bill, and it exposes the property to the children's creditors and divorces in the meantime.

Worked example 2: community property versus common law. A married couple owns a stock portfolio worth $1,000,000 with a $200,000 basis. One spouse dies.

• In a common law state with jointly held property, typically half gets a step-up. New basis = $100,000 (the survivor's untouched half of the original basis) + $500,000 (the stepped-up half) = $600,000. Selling the whole portfolio leaves a $400,000 gain, roughly $60,000 of federal tax at 15%.
• In a community property state (Arizona, California, Idaho, Louisiana, Nevada, New Mexico, Texas, Washington, Wisconsin, plus elective regimes elsewhere), community property receives a full double step-up on the first death. New basis = $1,000,000. Selling produces zero gain and zero tax.

Same couple, same portfolio, a $60,000 difference driven entirely by where they lived and how the asset was titled. Couples in community property states should confirm that their assets are actually characterized as community property, often through a community property agreement or a community property trust, because the default is not automatic for everything.

Two limits worth knowing. Retirement accounts get no step-up: a traditional IRA is taxed as ordinary income to whoever inherits it, which is why an IRA is a relatively poor asset to leave and a taxable brokerage account is an excellent one. And an estate may elect an alternate valuation date six months after death, useful when values have fallen, but only if it lowers both the estate value and the estate tax.

Estate tax thresholds and the 2026 change

Nearly everyone worries about the wrong tax here. The federal estate tax applies to a vanishingly small fraction of estates: on the order of one or two thousand taxable returns a year out of roughly three million deaths.

Legislation enacted in 2025 made the elevated exemption permanent and set it at $15 million per person beginning in 2026, indexed for inflation thereafter, replacing the scheduled reversion to roughly $7 million that had been widely planned around. The top rate above the exemption remains 40%.

Two features do most of the work for married couples:

• Unlimited marital deduction. Everything left to a US citizen spouse passes free of estate tax, without limit. (Non-citizen spouses are an exception and generally require a qualified domestic trust.)
• Portability. A surviving spouse can claim the deceased spouse's unused exemption, giving a couple a combined $30 million shield. Portability is not automatic: the executor must file a federal estate tax return (Form 706) within the deadline, even when no tax is owed, to make the election. Missing that filing is a genuinely expensive oversight for families near the threshold.

Also relevant: the annual gift tax exclusion is $19,000 per giver, per recipient in 2026, with no limit on the number of recipients and no filing required if you stay under it. Gifts above it do not usually cost tax, they simply consume lifetime exemption and require a Form 709. Payments made directly to a school for tuition or to a provider for medical care are unlimited and do not count as gifts at all, which is a quietly powerful tool for grandparents.

State estate and inheritance taxes are the real concern for most affected families. Roughly a dozen states plus the District of Columbia levy their own estate tax, several with exemptions in the $1 million to $7 million range, far below the federal level. A handful of states levy an inheritance tax, which is charged to the recipient and typically depends on their relationship to the deceased (spouses and children usually exempt, nieces and friends usually not). If you live in one of these states, or own real property in one, this is where planning actually pays.

Inherited retirement accounts

Rules for inherited IRAs and 401(k)s changed substantially and remain a common source of expensive errors.

Spouse beneficiaries keep the best treatment. A surviving spouse may roll the account into their own IRA and treat it as their own, using their own required minimum distribution schedule and, for a Roth, never being forced to take distributions at all.

Most non-spouse beneficiaries are subject to the 10-year rule: the entire account must be emptied by December 31 of the tenth year after death. Under final regulations, if the original owner had already begun required minimum distributions, the beneficiary must also take annual distributions in years one through nine, and empty the account in year ten. Missing a required distribution carries a penalty (25%, reduced to 10% if corrected promptly), so this is worth getting right.

Eligible designated beneficiaries escape the 10-year rule and may stretch distributions over their life expectancy: surviving spouses, minor children of the deceased (only until they reach majority, then the 10-year clock starts), disabled or chronically ill individuals, and anyone not more than ten years younger than the decedent.

The planning consequence is straightforward. A large traditional IRA left to a working-age child is now compressed into ten years of withdrawals stacked on top of that child's peak earning years, often at high marginal rates. Roth conversions during your own low-income years, and considering a charity as the beneficiary of traditional (rather than Roth) balances, are the standard responses. Inherited Roth IRAs are still subject to the 10-year emptying rule but the distributions are tax free, which makes a Roth by far the better retirement asset to leave behind.

Digital assets and the practical file

The technically valid plan that nobody can execute is a failure. Two practical pieces close the gap.

Digital access. Most states have adopted a version of the Revised Uniform Fiduciary Access to Digital Assets Act, which lets you authorize a fiduciary to access your accounts, but only if you say so. Use the platforms' own tools where they exist (legacy contacts, inactive account managers), grant explicit authority in your will and power of attorney, and store credentials in a password manager whose emergency access feature you have actually configured and tested. Note that cryptocurrency held in self-custody is uniquely unforgiving: if nobody can reach the seed phrase, the asset is gone permanently, and no court can recover it.

The practical file. One document, updated annually, telling your executor: where the estate documents are, the list of accounts and institutions (without passwords in the same place), insurance policies, the location of deeds and titles, safe deposit box details, who your attorney and accountant are, subscriptions to cancel, and any wishes about arrangements. Tell at least two people where it is. This document has no legal force and saves more grief per page than anything else in the plan.

Keeping the plan current

Review triggers, any one of which should prompt a look:

• Marriage, divorce, or the death of a spouse or beneficiary
• Birth or adoption of a child or grandchild
• A move to a different state, since estate law is state law
• A large change in net worth, or a business sale
• Buying real property, especially out of state
• A change in who you would trust as executor, trustee, guardian, or agent
• Significant changes in federal or state law
• Otherwise, every three to five years as a matter of routine

A note on choosing people. The executor's job is administrative and tedious rather than glamorous: inventories, notices, filings, and patience. Choose someone organized and even-tempered, not necessarily the eldest child. The guardian of your children and the trustee of their money do not have to be the same person, and often should not be: the person who would raise your children well is not always the person who should manage a seven-figure trust. Ask everyone before naming them, and name successors for every role.

Common mistakes

• Having no plan at all, which is the most common state of affairs and hands every decision to a statute and a judge.
• Stale beneficiary designations, which quietly override the will you carefully paid for.
• No contingent beneficiary, which drops the asset into probate the moment the primary predeceases you.
• Creating a trust and never funding it. An unfunded trust is a very expensive piece of paper.
• Gifting appreciated property during life and destroying a step-up worth far more than the probate it avoided.
• Adding a child as joint owner on a house or bank account for convenience, thereby making a gift, exposing the asset to their creditors, and disinheriting the other children.
• Naming a minor directly as beneficiary instead of a trust or custodial arrangement.
• Naming the estate as beneficiary of a retirement account, forcing probate and accelerating taxation.
• Skipping the Form 706 portability election after the first spouse's death for an estate anywhere near the threshold.
• Planning only for federal estate tax while ignoring a state estate or inheritance tax with a much lower threshold.
• Hiding the documents so well that nobody can find them. A perfect will in a locked safe with an unknown combination accomplishes nothing.
• Never telling anyone the plan. Most inheritance disputes are about surprise and perceived unfairness, not about money. A short, honest conversation while you are alive prevents a great many of them.

Bottom line. Estate planning for most households is not an exercise in tax avoidance; it is an exercise in reducing friction and preventing default rules from applying. Five documents, a clean set of beneficiary designations, TOD and POD registrations where they help, a trust only if your state or your goals actually call for one, and a practical file that tells someone where everything is. That combination handles the vast majority of situations. This is general education rather than legal or individualized financial advice, and because these rules are state-specific and change with legislation, a licensed estate attorney in your own state is worth the fee.
