The Short Answer

1. Does a Will Control Every Account?

A will is an important estate planning document. It can direct how property passing through an estate should be distributed, identify an executor, and express a parent’s wishes about who should care for minor children.

But not every asset passes through a will.

For example, when someone opens an IRA or enrolls in an employer retirement plan, they are typically asked to name a beneficiary.

That designation is a separate instruction about who should receive the account after the owner’s death.

Consider a simple example.

A married person prepares a will saying that their remaining property should be divided between their spouse and child.

Their IRA, however, names only the spouse as beneficiary.

Generally, the IRA goes to the named spouse under the account’s beneficiary provisions. It does not automatically get divided according to the will.

This does not mean the will is ineffective. It means the will and the account designation govern different transfers.

Plan rules, spousal rights, and applicable law can affect the result. The important point is that one document does not automatically update the other.

2. Which Assets Should You Review Separately?

Not every financial account is transferred in the same way.

Retirement accounts

IRAs, 401(k)s, and other retirement plans commonly use beneficiary designations.

The beneficiary on file with the custodian or plan administrator may control who receives the account after the owner’s death.

For employer retirement plans, federal spousal protection rules may apply. Under many plans, a married participant must obtain the spouse’s consent before naming someone else.

See the IRS guidance on retirement plan beneficiaries after marriage or the birth of a child.

Life insurance

Life insurance policies generally pay death benefits to the beneficiaries named under the policy.

A will does not ordinarily replace that beneficiary instruction.

Policy ownership, beneficiary changes, and the terms of the insurance contract still need to be reviewed separately.

Bank and investment accounts

Some bank accounts allow a payable-on-death (POD) designation. Brokerage accounts may offer a transfer-on-death (TOD) registration.

These arrangements can allow assets to pass directly to named beneficiaries rather than through the ordinary probate process.

Availability and legal effect depend on the account, institution, and applicable state law.

Real estate

Real estate requires a different review.

A house does not automatically pass according to the beneficiaries named on a retirement account or life insurance policy. How it transfers depends on title, ownership arrangements, estate planning documents, and applicable law.

For California homeowners, reviewing how property is titled is as important as reviewing a beneficiary form.

California community property

California is a community property state. Property acquired during marriage while domiciled in California is generally community property unless an exception applies.

That can include interests in retirement savings or life insurance funded during the marriage.

A beneficiary designation does not necessarily eliminate a spouse’s existing property rights. The result depends on how the asset was acquired, the applicable community property rules, and any federal law governing the account or plan.

This is one reason married couples should review beneficiary designations and property ownership together, rather than treating them as separate paperwork.

The practical question is not simply, “Do we have a will?”

It is, “Do the instructions for each asset lead to the result we want?”

3. What If the Beneficiary Is a Minor Child?

A minor child can be named as a beneficiary of certain accounts.

But naming the child does not mean the child can immediately manage the money.

Depending on the asset and arrangements in place, someone may need legal authority to hold or manage the inheritance until the child is old enough.

In California, the distinction between a guardian of the person and a guardian of the estate is important.

A guardian of the person is responsible for the child’s care.

A guardian of the estate manages the child’s money or property under court supervision when that type of guardianship is needed.

They are different responsibilities, and they do not necessarily have to belong to the same person.

A properly structured trust or another legally permitted arrangement may provide a different way to manage assets for a child. But naming a trust as a retirement-account beneficiary also introduces tax and distribution rules that need to be considered.

Parents should not assume that directly naming a child on every account is the simplest solution.

The more useful question is who should receive the financial benefit, who should manage it, and how the money should be available while the child is growing up.

4. What Happens If a Beneficiary Designation Is Missing or Outdated?

Beneficiary designations are easy to forget because they are often completed when an account is first opened.

A person might name a parent on their first retirement plan, get married several years later, have a child, and never review the original form.

The result may no longer reflect what they intended.

If no valid beneficiary designation exists, the account or plan’s default provisions may determine who receives the money. The estate may become the beneficiary in some circumstances.

This can also affect how quickly assets are distributed and which inherited retirement-account rules apply. For an IRA, having the estate rather than an individual as beneficiary can change the required distribution period.

Marriage, divorce, the birth of a child, or the death of a previously named beneficiary are good reasons to review the designations.

Divorce deserves particular attention.

Under California Probate Code §5040, certain nonprobate transfers to a former spouse may fail after divorce, subject to statutory exceptions and the effective-date rules in §5048. However, §5040 expressly excludes life insurance policies.

Employer benefit plans governed by ERISA may also be subject to federal rules that override state-law beneficiary revocation provisions.

Do not assume divorce automatically updates every beneficiary designation. Review life insurance policies and retirement accounts directly.

Changing a will does not automatically change an IRA beneficiary. And changing an IRA beneficiary does not necessarily update a will.

Both need attention.

5. Is an Inheritance Taxable Income?

This is where the type of asset matters.

Receiving property from someone who has died is generally not taxable income merely because it was inherited. But that does not mean everything received after death is tax-free.

Traditional IRAs and 401(k)s

Distributions from an inherited traditional IRA or pretax retirement plan are generally taxable to the beneficiary, except to the extent that the account contains amounts eligible for different tax treatment, such as after-tax basis.

For example, inheriting a $100,000 traditional IRA does not automatically mean reporting $100,000 of taxable income in the year of the owner’s death.

But when taxable amounts are distributed, the beneficiary generally reports those distributions as income.

The timing rules matter too.

For many individual non-spouse beneficiaries, the inherited account must be fully distributed by December 31 of the tenth year following the year of the owner’s death.

If the owner died before the required beginning date for distributions, annual withdrawals generally are not required during that ten-year period. If the owner died on or after the required beginning date, annual required minimum distributions generally apply as well.

Surviving spouses and certain other eligible beneficiaries can have different options.

A minor child of the deceased account owner can qualify for special distribution treatment. Under the federal retirement distribution regulations, that child generally reaches the age of majority at 21. The remaining inherited account then generally becomes subject to a ten-year distribution deadline.

This exception applies to the deceased account owner’s own child, not simply to any young beneficiary.

See IRS Publication 590-B for the applicable inherited IRA rules.

Roth IRAs

Inherited Roth IRAs also have beneficiary distribution requirements.

However, distributions that satisfy the Roth IRA qualified-distribution rules are generally tax-free. The five-year requirement can affect whether earnings are taxable.

Distributions made to a beneficiary because of the IRA owner’s death are generally exempt from the additional 10% early-distribution tax, even when part of the distribution is taxable.

An inherited Roth IRA is therefore not necessarily tax-free in every circumstance, and tax-free distributions do not mean that the account can be left untouched indefinitely.

Life insurance

Life insurance death benefits paid to a beneficiary are generally excluded from federal gross income.

Interest earned on those proceeds, however, is generally taxable. Special exceptions can apply to certain policies and transfers.

Stocks and real estate

Many inherited capital assets receive a basis generally determined by fair market value at the date of death, subject to exceptions and special valuation rules.

If the beneficiary later sells the asset, the gain or loss generally depends on the sale proceeds and the applicable basis.

That is different from an inherited traditional IRA, which does not receive the same general fair-market-value basis adjustment for its pretax income.

The distinction is between receiving an asset and recognizing taxable income from it.

6. Does Estate Tax Change Any of This?

Federal estate tax is different from the income tax that a beneficiary may owe.

Estate tax concerns the taxable estate of the deceased person. Income tax concerns taxable income, including certain distributions or earnings received by beneficiaries.

For 2026, the federal basic estate tax exclusion amount is $15 million. Prior taxable gifts and other circumstances can affect the available exclusion and the estate tax calculation.

Many households will not owe federal estate tax.

But that does not eliminate the need to review beneficiary designations.

A family can have no federal estate tax liability and still face questions about who receives a retirement account, who manages a child’s inheritance, or when an inherited IRA must be distributed.

The same estate plan can also have different results for different assets.

That is why estate planning should not begin and end with an estate tax calculation.

7. What Should Families Review Before They Need the Documents?

A practical review can begin with a list of accounts and important records.

For retirement accounts, confirm the primary and contingent beneficiaries currently on file. Do not rely only on what you remember entering years ago.

Review life insurance policies separately.

For bank and brokerage accounts, confirm whether POD or TOD provisions exist and whether they match the intended plan.

For real estate, review ownership and title with the appropriate professional rather than assuming the will controls every transfer.

If minor children are involved, consider who would care for them, who would manage inherited assets, and whether a trust or another arrangement would be appropriate.

It is also worth keeping a secure record of where important documents can be found, without putting passwords and sensitive account credentials into an ordinary shared document.

The goal is not to create a complicated file.

It is to make sure that someone else could understand what exists, who to contact, and what decisions have already been made.

Common Mistakes

If I have a will, do I still need to check my beneficiaries?
Yes. Certain accounts can pass under their own beneficiary designations. A will does not automatically update those instructions.

Can I name my child directly as the beneficiary?
Often, yes. But a minor child generally cannot independently manage inherited financial assets. The right arrangement depends on the asset, the child’s age, and the relevant legal and tax rules.

If my spouse is named in my will, will they automatically receive my 401(k)?
Not necessarily because of the will itself. Employer retirement plans have beneficiary rules, and federal spousal protections often apply. The plan documents and beneficiary designation should be reviewed.

Is money inherited from a parent always tax-free?
No. Inherited cash or other property may generally be received without federal income tax on the inheritance itself, but taxable retirement-account distributions and income earned afterward can still create tax.

Do I need estate planning if I will never owe federal estate tax?
Estate planning addresses more than estate tax. Beneficiaries, minor children, account access, ownership, and the management of assets can matter even when no estate tax is expected.

The Key Distinction

1. A will does not automatically control assets that pass under valid beneficiary designations or other nonprobate arrangements.
2. Who receives an asset, who manages it, and how it is taxed are separate questions.
3. Reviewing beneficiary forms before a major life change becomes an emergency can matter more than preparing documents that no one else knows how to find.
