Estate and succession planning means deciding, in writing and in advance, who inherits your property, who manages your affairs if you cannot, and how your business continues after you step away or die. For 2026, the federal estate tax exemption sits at $15 million per person, so most families will owe no federal estate tax.1Internal Revenue Service. Whats New – Estate and Gift Tax That threshold does not protect you from probate costs, state-level taxes, family disputes, or the default rules that take over when no plan exists. Without written instructions, state intestacy laws divide your assets on a formula that rarely matches what you would have chosen.
What to Gather Before You Start
A workable plan begins with knowing exactly what you own, what you owe, and who you want to benefit. Pull together bank statements, brokerage accounts, retirement account summaries, life insurance policies, real estate deeds, vehicle titles, and any digital assets such as cryptocurrency wallets or revenue-generating online accounts. On the other side of the ledger, list every debt: mortgages, car loans, student loans, credit card balances. Subtracting liabilities from assets gives you the net estate value that drives most decisions that follow.
For each intended beneficiary and any business successor, write down the full legal name and current address exactly as they appear on government-issued identification. Mismatched names are one of the fastest ways to trigger a court challenge. For real estate, use the legal description from the deed rather than a street address. The legal description is what the county recorder’s office uses to identify the parcel, and a street address alone can create ambiguity.
Collect contact information for every financial institution, life insurance company, and retirement plan administrator connected to your accounts. Your executor or trustee will need it to locate and claim assets. If you hold digital assets, document the location of private keys, recovery phrases, and two-factor authentication devices in a secure memorandum kept separate from the devices themselves. Outdated account numbers or missing beneficiary information can delay distributions for months.
The Documents That Do the Work
Wills and Trusts
A last will and testament is the foundational document. It names the people who inherit your property, appoints a personal representative (executor) to manage your estate through probate, and, if you have minor children, designates a guardian. Every asset not covered by a trust, beneficiary designation, or joint ownership arrangement passes through your will and into probate.
A revocable living trust lets you transfer assets into a trust structure during your lifetime while keeping full control as the trustee. You can change, amend, or dissolve it at any time. When you die, a successor trustee you have named takes over and distributes assets to beneficiaries without probate, avoiding a public court proceeding that can be slow and costly depending on where you live.2Consumer Financial Protection Bureau. What Is a Revocable Living Trust The catch that trips up a remarkable number of people: a revocable trust only works for assets you actually retitle into it. Create the trust but never transfer your bank accounts, brokerage accounts, or real estate into the trust’s name, and those assets still go through probate as if the trust did not exist.
Irrevocable trusts go further. Once you transfer assets into an irrevocable trust, you give up ownership and control. In exchange, those assets are no longer part of your taxable estate, which can reduce estate tax exposure for very large estates, and they gain stronger protection from creditors. The specific type matters. A qualified terminable interest property (QTIP) trust, for example, guarantees all income to a surviving spouse while preserving the remaining principal for children from a prior marriage. A QTIP election must be made on the federal estate tax return.
Powers of Attorney and Healthcare Directives
A durable financial power of attorney names someone to handle your money, pay your bills, and manage your investments if you become incapacitated. Without one, your family may need to petition a court for a guardianship or conservatorship, which is expensive and slow. A healthcare power of attorney (sometimes called a healthcare proxy) names someone to make medical decisions on your behalf when you cannot communicate your own wishes. A separate living will or advance directive spells out your preferences for end-of-life care, such as whether you want life-sustaining treatment.
One document that many plans overlook is a HIPAA authorization. Federal privacy regulations prohibit healthcare providers from sharing your medical information with anyone, including family members, unless you have signed a written authorization allowing it.3eCFR. 45 CFR 164.508 – Uses and Disclosures for Which an Authorization Is Required Your healthcare agent may have the legal authority to make decisions, but without a HIPAA release on file, doctors and hospitals can refuse to disclose the information the agent needs to make them. Sign one and give copies to your primary care physician, your healthcare agent, and any hospital you use regularly.
Letter of Final Instructions
A letter of final instructions is an informal, non-binding document that fills gaps the legal papers do not cover. Funeral preferences, the location of important papers, passwords for online accounts, personal messages to family members. Because it is not legally enforceable, it does not need witnesses or notarization, and you can update it whenever you like. Think of it as the operating manual your executor reads alongside the formal documents.
Beneficiary Forms Beat Your Will
This is where most estate plans quietly fall apart. Life insurance policies, 401(k)s, IRAs, annuities, and any bank or brokerage account with a payable-on-death (POD) or transfer-on-death (TOD) designation pass directly to whoever is named on the beneficiary form, regardless of what your will says. If your will leaves everything to your current spouse but your 401(k) still lists your ex-spouse from a decade ago, the 401(k) goes to your ex-spouse. Courts consistently enforce the beneficiary form over the will.
For employer-sponsored retirement plans, this rule is reinforced by federal law: plan administrators must follow the beneficiary designation on file, even when a divorce decree says otherwise.4U.S. Department of Labor. Current Challenges and Best Practices Concerning Beneficiary Designations in Retirement and Life Insurance Plans Review every beneficiary designation at least once a year and immediately after any marriage, divorce, birth, or death. A five-minute form update at your financial institution can prevent an outcome no amount of litigation will fix after the fact.
Federal Estate and Gift Taxes in 2026
The Exemption
The One Big Beautiful Bill Act, signed on July 4, 2025, set the basic exclusion amount at $15 million for anyone dying in 2026, with future inflation adjustments.5Office of the Law Revision Counsel. 26 USC 2010 – Unified Credit Against Estate Tax A married couple can effectively shelter up to $30 million by using both spouses’ exemptions. Your gross estate includes everything you own or have an interest in at death: real estate, investments, retirement accounts, life insurance proceeds, and business interests.6Office of the Law Revision Counsel. 26 USC 2031 – Definition of Gross Estate Only the amount above your exemption is taxed, and the top federal estate tax rate is 40%.7Congress.gov. The Estate and Gift Tax – An Overview
Portability Between Spouses
When the first spouse dies without using all of their $15 million exemption, the surviving spouse can claim the leftover amount, a concept called portability. It is not automatic. The deceased spouse’s estate must file a federal estate tax return (Form 706) even if no tax is owed, specifically to elect portability.5Office of the Law Revision Counsel. 26 USC 2010 – Unified Credit Against Estate Tax The standard deadline is nine months after death, with extensions available. For estates that miss that window but do not otherwise owe estate tax, the IRS provides a simplified late-election method with a five-year filing deadline.8Internal Revenue Service. Revenue Procedure 2022-32 Failing to file this return means forfeiting millions of dollars in exemption that can never be recovered. Portability applies only to the federal estate and gift tax exemption. It does not extend to the generation-skipping transfer tax exemption or to any state-level estate tax.
Annual Gift Exclusion
You can give up to $19,000 per recipient in 2026 without filing a gift tax return or reducing your lifetime exemption. Married couples who agree to split gifts can give $38,000 per recipient.9Internal Revenue Service. Frequently Asked Questions on Gift Taxes Gifts above the annual exclusion are not immediately taxed; they simply reduce the $15 million you can pass tax-free at death. Gifting during your lifetime shrinks the taxable estate and moves appreciating assets out of your name before they grow further.
The Marital Deduction
Any amount of property passing from one spouse to another is completely exempt from federal estate tax, with no dollar limit, whether the transfer happens during life or at death.10Office of the Law Revision Counsel. 26 USC 2056 – Bequests, Etc., to Surviving Spouse One important exception: if the surviving spouse is not a U.S. citizen, the marital deduction is disallowed unless the assets pass through a qualified domestic trust (QDOT). Couples in that situation need specific trust planning to avoid an immediate tax bill on the first spouse’s death.
Generation-Skipping Transfer Tax
Leaving assets directly to grandchildren or anyone more than 37.5 years younger than you triggers a separate tax called the generation-skipping transfer (GST) tax. The GST rate is also 40%, applied on top of any estate tax already owed.11Congress.gov. The Generation-Skipping Transfer Tax Each person gets a GST exemption equal to the basic exclusion amount, $15 million for 2026.12Office of the Law Revision Counsel. 26 USC 2631 – GST Exemption Unlike the estate tax exemption, the GST exemption is not portable between spouses. If the first spouse dies without allocating theirs, it is lost. Trusts designed for grandchildren need careful GST planning to avoid a combined effective rate that can consume more than half the transfer.
State Estate and Inheritance Taxes
The $15 million federal exemption gives many families a false sense of security. Roughly 17 states and the District of Columbia impose their own estate tax or inheritance tax, and their exemptions are dramatically lower. State estate tax thresholds start as low as $1 million, meaning a family well below the federal threshold can still owe six figures to the state. A handful of states impose an inheritance tax instead, based on the beneficiary’s relationship to the deceased: close relatives typically pay little or nothing, while distant relatives and unrelated beneficiaries face higher rates.
State-level portability is generally not available. Even if you elect portability for federal purposes, your surviving spouse may not be able to use the first spouse’s unused state exemption. If you own real estate in multiple states, each state where property is located can impose its own estate tax on that property’s value. The interaction of federal and state rules is why families with estates in the $1 million to $15 million range often still benefit from trust-based planning even when no federal tax is at stake.
Step-Up in Basis for Inherited Assets
When you inherit property, its tax basis resets to fair market value on the date the owner died.13Office of the Law Revision Counsel. 26 USC 1014 – Basis of Property Acquired From a Decedent This step-up wipes out all the capital gains that accumulated during the decedent’s lifetime. If your parent bought a house for $100,000 and it is worth $500,000 when they die, your basis is $500,000. Sell it the next day for $500,000 and you owe zero capital gains tax. Had your parent gifted you the same house during their lifetime, you would inherit their original $100,000 basis and owe tax on $400,000 of gain.
Timing and transfer method matter enormously. For highly appreciated assets, real estate, stock held for decades, business interests, the step-up at death delivers a larger tax benefit than gifting during life, even though gifting reduces the estate’s size for estate tax purposes. In community property states, a surviving spouse can receive a step-up on the entire value of community property, not just the deceased spouse’s half. This is the kind of detail that can save or cost a family hundreds of thousands of dollars depending on which transfer method they choose.
Planning for a Beneficiary With Special Needs
Leaving money directly to a person who relies on Medicaid or Supplemental Security Income (SSI) can disqualify them from the benefits that pay for their daily care. Federal law limits countable resources for SSI eligibility to $2,000 for an individual, and even a modest inheritance can push someone over that line. A special needs trust solves this by holding assets for the beneficiary’s benefit without giving them direct ownership. The trustee can spend trust funds on things government benefits do not cover, such as private therapy, recreation, specialized equipment, or education, but cannot make direct cash payments to the beneficiary without risking eligibility.
Two types of special needs trust serve different situations. A third-party trust, funded by a parent or grandparent with their own money, does not require reimbursing the state for Medicaid costs when the beneficiary dies. Whatever remains passes to other family members. A first-party trust, funded with the beneficiary’s own assets (typically from a lawsuit settlement or direct inheritance), must include a Medicaid payback provision: when the beneficiary dies, remaining trust funds repay the state for Medicaid benefits provided during the beneficiary’s lifetime.14Office of the Law Revision Counsel. 42 USC 1396p – Liens, Adjustments and Recoveries, and Transfers of Assets The type of trust and the source of funding determine whether the family keeps remaining assets or the state takes them. Getting this wrong is expensive and largely irreversible.
Spousal Elective Share
In most separate-property states, a surviving spouse has a statutory right to claim a portion of the deceased spouse’s estate regardless of what the will says. This right, commonly called the elective share, typically entitles the surviving spouse to roughly one-third of the probate estate, though the exact fraction and calculation method vary. Community property states handle spousal protection differently, giving each spouse an automatic ownership interest in marital property during the marriage itself.
You generally cannot completely disinherit a spouse through a will alone. If your plan intentionally leaves less than the elective share to a surviving spouse, they can petition the court to override the will. Prenuptial or postnuptial agreements can waive elective share rights, but the waiver must meet specific legal requirements to hold up. If you are in a second marriage with children from a prior relationship, the tension between the elective share and your desire to provide for those children is one of the first issues a plan needs to address.
Business Succession
Buy-Sell Agreements
A buy-sell agreement is the backbone of any business succession plan. It establishes in advance what happens to an owner’s interest when they die, become disabled, or retire. In a cross-purchase arrangement, the remaining owners buy the departing owner’s share directly, often funded by life insurance policies each owner carries on the others. The surviving owners increase their ownership basis by the purchase price, which reduces their future capital gains tax. In an entity-redemption arrangement, the company itself buys back the departing owner’s interest using company funds or insurance proceeds. The right structure depends on the number of owners, the entity type, and the tax consequences each option creates.
Every buy-sell agreement needs a reliable valuation method and a mechanism for periodic updates, so the purchase price reflects current value rather than what the business was worth five years ago. A buy-sell agreement without an updated valuation is almost worse than no agreement at all, because it locks in a price that one side will inevitably view as unfair.
S-Corporation Succession Constraints
S corporations face unique restrictions on who can own shares. Eligible shareholders are limited to individuals, estates, and certain qualifying trusts.15Office of the Law Revision Counsel. 26 USC 1361 – S Corporation Defined When an S-corp shareholder dies, the estate can hold shares for up to two years. After that window closes, the shares must transfer to an eligible shareholder or into a qualifying trust, or the company loses S-corp status entirely and becomes a C corporation, triggering double taxation on all future income. Two trust structures preserve S-corp eligibility: a qualified subchapter S trust (QSST), which must have a single income beneficiary, and an electing small business trust (ESBT), which can have multiple beneficiaries. Both require timely elections filed within roughly two and a half months of the transfer. Missing that deadline costs the company its tax status.
Separating Control From Economic Interest
Founders of closely held businesses often want to pass the financial value of the company to all their children while keeping decision-making authority with whichever child actually runs the business. Voting and non-voting stock accomplishes this. The successor who manages the business receives voting shares; siblings who are not involved receive non-voting shares that entitle them to dividends and appreciation but not operational control. Formalizing these arrangements in the company’s operating agreement or bylaws, with buy-sell provisions that trigger automatically on death or disability, avoids negotiations during a crisis when emotions run high and leverage is uneven.
Signing, Storing, and Updating
Legal documents carry no weight until they are properly signed. Nearly every state requires at least two disinterested witnesses to watch you sign a will and then sign it themselves. “Disinterested” means the witnesses do not inherit anything under the will. Witnesses verify your identity, your understanding of what you are signing, and the absence of coercion. Notarization adds a further layer of authentication: a notary public confirms identities and administers oaths. Failing to meet witness or notarization requirements can invalidate the entire document, handing your family the exact legal battle the plan was supposed to prevent.
When business ownership changes hands, the company’s internal records need updating too: amended corporate minutes, a revised operating agreement, and updated articles of organization or incorporation filed with your state’s Secretary of State. Forging or fraudulently altering estate planning documents like wills, deeds, or trust instruments is a felony in every state, carrying potential prison time and substantial fines.
Store original signed documents in a fireproof safe or a bank safe deposit box. Tell your executor, trustee, and healthcare agent exactly where to find them. A plan nobody can locate when it is needed is functionally identical to no plan at all. Give copies of healthcare directives to your primary physician and any hospital where you receive regular care so they are already in your medical file before an emergency. Update beneficiary designations on life insurance, retirement accounts, and POD/TOD accounts at the financial institution level, since those designations pass assets outside probate and override your will.
An estate plan is not a set-it-and-forget-it document. Certain life events should trigger an immediate review: marriage, divorce, the birth or adoption of a child, a significant change in net worth, the death of a named beneficiary or executor, and a move to a different state. Divorce is particularly dangerous. Some states automatically revoke provisions benefiting an ex-spouse in a will or trust, but beneficiary designations on retirement accounts and life insurance are governed by the account contract, not state probate law. An ex-spouse listed on a 401(k) beneficiary form will inherit those funds unless you change the form.
Even without a major life event, review your plan every three to five years. Tax laws change, asset values shift, and the people you named as agents or executors may no longer be willing or able to serve. Check that every trust you have created is actually funded with the assets it is supposed to hold. Verify that beneficiary designations across all financial institutions still match your current intentions. The families that run into the worst problems are not the ones who never made a plan; they are the ones who made a plan once and never looked at it again.
