What an estate plan covers
An estate plan answers two sets of questions. The first is about your lifetime: who pays your bills, manages your investments and makes medical decisions if an illness or accident leaves you unable to. The second is about your death: who receives each asset, who settles your affairs, who raises minor children and how much is lost to taxes, fees and delay.
For most households the plan is about control rather than tax, because the federal estate tax reaches only estates above $15,000,000 per person in 2026. A young parent with a modest 401(k) and a term life insurance policy often needs a plan more urgently than a wealthy retiree, because a Will is where you nominate a guardian for your children.
How your assets actually pass at death
A common surprise is how little of a typical estate a will controls. Property reaches the next owner through one of four channels, and the first three bypass both the will and Probate, the court process for settling an estate.
Because the channels override one another in this order, the plan only works if they agree. A 401(k) still naming a former spouse goes to that person even if a newer will says otherwise, and federal law generally requires a spouse’s written consent before anyone else can be named on most 401(k) plans. In the nine community property states, each spouse can leave only their own half of community assets.
- Beneficiary designations: retirement accounts, life insurance and annuities are paid to the people named on the account’s form, whatever the will says.
- Titling: joint accounts with right of survivorship and transfer-on-death or payable-on-death registrations pass straight to the survivor or named beneficiary.
- Trusts: assets retitled into a revocable living trust are distributed by the successor trustee under the trust’s terms.
- The will, or state intestacy law if there is none: everything else, which goes through probate.
An estate planning checklist in seven steps
A workable plan comes together in a set order. The inventory comes first because it shows which assets a will would even touch, and the beneficiary forms come next because they usually move more money than the will does. Signing rules for the documents are set by each state, so most people use an attorney licensed where they live, especially with a business, a blended family or property in more than one state.
- List what you own, how each asset is titled and whether it already names a beneficiary.
- Name primary and contingent beneficiaries on every retirement account, insurance policy and annuity, and add transfer-on-death registrations where they fit.
- Sign a will that names an executor, a guardian for minor children and who receives everything else.
- Sign a durable financial power of attorney, a health care power of attorney and a living will.
- Decide whether a revocable living trust earns its cost: property in several states, privacy, a blended family or heirs who should not inherit outright.
- Check federal and state estate and inheritance tax exposure, and which heirs would owe income tax on what they receive.
- Tell your executor and agents where the originals are, and review everything after a marriage, divorce, birth, death, move or large change in wealth.
Estate and gift taxes in 2026
For deaths in 2026, the federal basic exclusion amount is $15,000,000 per person, set by the One Big Beautiful Bill Act with no scheduled sunset and indexed for inflation after 2026. Only the taxable estate above it is taxed, at rates that top out at 40%. Property left outright to a US citizen spouse qualifies for the unlimited marital deduction, and bequests to qualified charities are deductible.
A married couple can effectively shelter $30,000,000 through portability, which lets a surviving spouse use the first spouse’s unused exclusion. It is not automatic: the executor must elect it on a Form 706, even when no tax is due. The return is due nine months after death, though an estate filing only to elect portability can use a simplified late election for up to five years, and skipping it altogether is a common and expensive oversight. Lifetime gifts draw on the same exclusion, but in 2026 you can give up to $19,000 per recipient without filing a gift tax return.
State taxes can matter more. Twelve states and the District of Columbia levy their own estate tax, several with exemptions far below the federal amount, and a handful, including Pennsylvania, New Jersey and Kentucky, charge an inheritance tax on what some heirs receive.
The income tax your heirs will owe
Estate tax is only half the tax picture. The other half is the income tax your heirs pay, which depends on the kind of account they inherit.
Taxable brokerage accounts, stocks and real estate usually get a step-up in basis to their value at death, erasing the capital gain built up during your life. Pre-tax money in a traditional IRA or 401(k) gets no step-up: every dollar is ordinary income to the heir when withdrawn, and most non-spouse beneficiaries must empty an inherited IRA within ten years. Roth accounts generally pass free of income tax.
That difference shapes good plans. Leaving pre-tax accounts to a charity, which owes no income tax, and taxable or Roth assets to family raises what the family keeps. A Roth conversion moves the tax onto your own return, which pays off when your bracket is lower than your heirs’ will be.
Common estate planning mistakes
Most estate plans fail through neglect rather than bad drafting. Documents signed years ago no longer match the family, the assets or the state the owner now lives in, and accounts opened since then carry beneficiary forms nobody compared with the will. A move matters more than people expect, because a new state can change the signing rules, a spouse’s property rights and whether an estate or inheritance tax applies.
- Beneficiary forms never updated after a divorce, or with no contingent beneficiary named.
- Naming a minor child directly on an account, which can force a court-supervised guardianship of the money.
- Signing a living trust but never retitling assets into it, so they go through probate anyway.
- Adding an adult child to a bank account or deed as a shortcut, which exposes the asset to that child’s creditors and may be a taxable gift.
- Planning only for death, with no power of attorney in place when an illness or accident strikes.
Illustrative numbers
Three $500,000 inheritances with very different after-tax values
- Gross estate
- Everything owned at death at fair market value, including life insurance you own, retirement accounts and your share of jointly held property
- Debts
- Mortgages, loans, final bills and the final income tax return
- Settlement costs
- Probate, legal, appraisal and administration fees, plus selling costs
- Estate and inheritance taxes
- Federal tax above the exclusion plus any state tax
- Heirs’ income tax
- Ordinary income tax on inherited traditional IRA or 401(k) withdrawals
The IRS gross estate counts probate and non-probate property alike, so avoiding probate does not reduce estate tax.
Traditional IRA, heir taxed at a flat 24% on withdrawals$120,000 income tax, $380,000 kept
Brokerage account worth $500,000, bought for $200,000Basis steps up to $500,000 at death
Tax if the heir sells the brokerage holdings right away$0, so $500,000 kept
Same sale if there were no step-up, at the 15% rate$45,000 tax on a $300,000 gain
Roth IRA that has met its five-year period$0 tax, $500,000 kept
Federal estate tax on the $1.5 million total$0, far below the $15 million exclusion
Equal balances are not equal gifts: the heir of the traditional IRA keeps $120,000 less than the heir of the Roth. For an estate this far below the federal exclusion, directing pre-tax money to charity or converting it during life does more for the heirs than federal estate tax planning could.

Estate Planning in MoneyWhatIf
MoneyWhatIf’s Estate page reads the final year of your projection and follows the gross estate through debts, beneficiary income tax on pre-tax accounts, property selling costs, charitable giving, administration costs and state and federal estate tax to an estimated net for beneficiaries, charging capital-gains tax only if you switch off the step-up in basis. Its defaults include a 25% beneficiary tax, a $15 million federal exemption ($30 million for a couple) and a 40% rate, and each can be changed. It does not draft documents, model trusts or prior gifts, or check that a portability election was actually made.
Common questions
Estate Planning FAQs
Do I need an estate plan if I’m not wealthy?
Usually, yes. Without one, state law decides who inherits your probate property, and a court picks the person who settles your estate and, if you have young children, their guardian. If you become incapacitated, your family may need a court guardianship just to pay your bills. Updated beneficiary forms, a simple will and powers of attorney solve most of this at modest cost.
At what age should you start estate planning?
As soon as you are an adult. Once a child turns 18, parents generally cannot make medical or financial decisions for them without legal authority, so even a college student benefits from health care and financial powers of attorney. A fuller plan usually follows marriage, a home or a first child, and the tax questions grow as retirement approaches.
What is the difference between an estate plan and a will?
A will is one document inside an estate plan. It speaks only at death and governs only property that passes through probate. An estate plan also covers incapacity through powers of attorney and health care directives, coordinates beneficiary designations and account titles, may use trusts, and considers the estate, inheritance and income taxes your heirs will face.
