Your retirement accounts, IRAs, and life insurance policies do not transfer at your death the way a checking account or a piece of real estate does. They carry their own instructions, embedded in a form that you likely completed once, often at enrollment, and rarely revisited. Those instructions are legally binding, and they operate entirely outside of any will or trust you create.

Why Do Your Beneficiary Designations Override Your Will?
Your beneficiary designations are not estate documents. They are contractual instructions filed with a financial institution, insurance company, or retirement plan administrator. When you name a beneficiary, that instruction is a binding agreement between you and the custodian, one that does not require probate to carry out.
Your will governs the distribution of assets that are part of the probate estate. Assets with valid beneficiary designations, such as your IRAs, 401(k) and 403(b) plans, annuities, and life insurance policies, generally pass directly to your named beneficiaries outside of probate and are not controlled by your will. However, if no valid beneficiary is designated or the designation fails, these assets may be paid to your estate and become subject to probate.
The practical consequences are significant. If you updated your will to reflect a second marriage, but never updated the beneficiary designation on a 401(k) from a prior marriage, you may inadvertently leave that account to a former spouse. Courts have consistently enforced the beneficiary designation as written. Similarly, if you believe a trust will govern how your retirement assets pass to your children, you may find that accounts with outdated or mismatched designations bypass the trust entirely. Your intent and your documentation are two different things.
How Should You Name Your Primary and Contingent Beneficiaries?
Most retirement account forms allow, and careful planning generally calls for, you naming both primary and contingent beneficiaries.
Your primary beneficiary receives your account assets directly upon your death. If your primary beneficiary predeceases you, or formally disclaims the inheritance, your contingent beneficiary receives the assets instead.
When no contingent beneficiary is named and your primary beneficiary is no longer living, your account generally passes to your estate. Assets that pass to your estate are subject to probate, face a less favorable distribution timeline, and lose many of the tax-deferral benefits that make inherited retirement accounts valuable.
Naming multiple primary beneficiaries who share your account is permitted and is common, particularly when you want to divide your assets among multiple children. The form typically allows percentage allocations, and those percentages must total 100%.
Per Stirpes vs. Per Capita: How Do Your Shares Pass to Your Heirs?
Many beneficiary designation forms offer you a choice between per stirpes and per capita distribution. This election determines what happens if a beneficiary dies before you do. Under a per stirpes designation, a deceased beneficiary's share passes to their descendants, typically their children. Under a per capita designation, only surviving named beneficiaries at the time of your death inherit, and the descendants of a deceased beneficiary do not receive that share unless they are separately named.
Neither approach is universally correct. Per stirpes generally preserves your family line of inheritance, while per capita typically concentrates your inheritance among surviving named beneficiaries. The appropriate choice depends on your intentions and your family circumstances.
As a Spousal Beneficiary: What Different Rules Apply to You?
If you are a surviving spouse who inherits a retirement account, you have options that are not available to other beneficiaries.
Spousal rollover. As a surviving spouse, you may roll an inherited IRA or 401(k) directly into your own IRA. Once rolled over, the account is treated as your own, meaning your distributions are governed by your own required minimum distribution schedule, not the accelerated timelines that apply to inherited accounts. When you are younger than the deceased, this approach can meaningfully defer your RMD obligations.
Treating as inherited. Alternatively, as a surviving spouse, you may keep the account as an inherited IRA. This can be advantageous when you are under age 59½ and need to access funds before that age without the 10% early withdrawal penalty, since distributions from an inherited IRA are not subject to that penalty regardless of your age.
As a spousal beneficiary, you are also exempt from the SECURE Act's 10-year rule, described below. Surviving spouses like you remain eligible for life-expectancy-based distributions, which can preserve decades of tax-deferred growth that other beneficiaries cannot access under current law.
The SECURE Act and Your 10-Year Rule as a Non-Spousal Beneficiary
Before 2020, many non-spousal beneficiaries could stretch required minimum distributions from an inherited IRA over their own life expectancy, a provision informally known as the "stretch IRA." If you were a 40-year-old inheriting a substantial IRA, you could spread required distributions across four decades, allowing much of the account to continue compounding in a tax-deferred environment.
The Setting Every Community Up for Retirement Enhancement (SECURE) Act, enacted in December 2019, fundamentally changed this for most beneficiaries like you. Under current federal law, if you are a non-spousal beneficiary who inherits an IRA from an account owner who died on or after January 1, 2020, you must fully distribute your inherited IRA within ten years of the account owner's death.
The 10-year rule reflects the SECURE Act as enacted and IRS guidance published as of the date this article was written. Regulatory interpretation of the specific distribution requirements within the ten-year window has evolved and may continue to evolve; consult a qualified tax professional or estate planning attorney for the applicable rules in any specific situation.
What the 10-Year Rule Means for You
There are no required minimum distributions during your ten-year window; your account simply must be empty by the end of the tenth year. You have discretion over how you take distributions across those years, but that flexibility does not change the fundamental constraint: a large IRA you inherit must be fully distributed within a decade.
The tax consequence is the compression of what was previously a lifetime distribution into ten years. If you are a high earner, a professional in your 40s or 50s who inherits a $600,000 IRA from a parent, you must absorb that full balance into your taxable income within a decade, on top of your existing income. If you are already in the 32% or 37% federal bracket, each dollar of your distribution is taxed at those rates, plus applicable California state income tax.
California taxes your IRA distributions as ordinary income, with no exclusion or preferential rate for retirement income. At California's current top marginal rate of 13.3% under current state law, if you are a California resident inheriting a large IRA, you face a combined federal and state marginal rate on those distributions that can be substantial. This is a meaningfully different outcome than what the stretch IRA provided under the prior rules.
California marginal income tax rates reflect current law as of the date this article was written. Tax rates are subject to change.
Are You an Eligible Designated Beneficiary?
A specific category of beneficiaries, known as eligible designated beneficiaries (EDBs), are not subject to the 10-year rule and may still use life-expectancy-based distributions. Under current law, you may be an eligible designated beneficiary if you are:
- Surviving spouses
- Minor children of the original owner (until they reach the age of majority, after which the 10-year rule begins)
- Disabled or chronically ill individuals (as defined by IRS rules)
- Individuals who are not more than ten years younger than the deceased account owner
Most working-age children inheriting from a parent will not qualify as EDBs and will be subject to the 10-year rule.
Minor children of the account owner (not grandchildren) are a particular case. They qualify as EDBs, but only until they reach the age of majority. At that point, the 10-year rule begins, and the entire account must be distributed within ten years of their birthday. Naming a young child as beneficiary does not provide long-term deferral; it simply delays, and then concentrates, the distribution requirement.
Common Errors You Should Avoid in Your Beneficiary Designation
Several patterns of error appear frequently in beneficiary designation reviews.
Stale designations. Your beneficiary form completed at enrollment may name your parents, a former spouse, or individuals who are now deceased, estranged, or simply no longer your intended recipients. Life events, including your marriage, divorce, the birth of your children, or the death of a previously named beneficiary, do not automatically update your designation. The custodian has no obligation to look beyond the form on file.
Naming your estate. If you name your estate as beneficiary, you eliminate the contractual transfer mechanism that allows your retirement accounts to bypass probate. Your account enters your estate, is subject to probate, and faces a compressed five-year distribution rule (if you died before beginning your RMDs) rather than the more favorable inherited IRA rules available to individual beneficiaries. There are narrow circumstances where naming your estate may be intentional, but it is generally not the intended outcome when chosen without deliberate planning.
Naming a minor child directly. A minor cannot legally own an inherited IRA outright. If you name a minor directly as beneficiary, a court-appointed guardian or custodian may be required to manage the account, a process that involves legal costs and court oversight. Naming a properly drafted trust for the benefit of the minor may be a more controllable approach for you, though the rules governing inherited IRAs held in trust are technical and require careful coordination between your estate planning attorney and your financial advisor.
Neglecting contingent beneficiaries. If all your primary beneficiaries predecease you and no contingents are named, your account likely passes to your estate. Naming contingent beneficiaries, and reviewing them alongside your primary designations, is a basic planning safeguard for you.
Mismatch with your estate plan. A broader estate plan you create may include a revocable living trust intended to govern how your assets pass to your heirs. If your retirement account beneficiary designations are not coordinated with that trust, your accounts may bypass the trust entirely and pass in a way that conflicts with your overall plan. Trusts can receive your inherited IRA assets, but your trust document must meet specific IRS requirements to preserve favorable distribution treatment. This is a technical area where your estate planning attorney and your financial advisor need to be working from the same plan.
If You're in California: Community Property Considerations for Your Accounts
California is one of nine community property states in the United States. Under California law, if you acquired assets during your marriage using marital funds, they are generally considered community property, jointly owned by you and your spouse in equal shares regardless of which spouse's name appears on the account.
This principle interacts with retirement accounts in ways that are not always intuitive.
ERISA-governed plans. For most employer-sponsored retirement plans subject to ERISA, including 401(k) plans and many 403(b) and pension plans, the spouse is the default beneficiary for pre-retirement death benefits. A participant who wishes to name a non-spouse beneficiary, such as a child or a trust, generally must obtain the spouse's written consent, signed and witnessed by a plan representative or notary public. This consent requirement is strongest in defined contribution plans and in pension plans subject to the Qualified Joint and Survivor Annuity (QJSA) rules; specific requirements can vary by plan type and whether the benefit involves a pre-retirement or post-retirement election. ERISA generally preempts California community property law for purposes of plan administration and beneficiary designation. One significant statutory exception is the Qualified Domestic Relations Order (QDRO), which allows a state court order to assign a portion of a retirement plan benefit to an alternate payee, typically a former spouse, in connection with divorce or legal separation.
IRAs. IRAs are not governed by ERISA's spousal consent requirement. A California IRA owner may, as a matter of federal retirement account law, name any beneficiary they choose. However, California community property law does not simply disappear. If IRA contributions were funded with community property assets, the surviving spouse may have a legal claim to a portion of the account regardless of the beneficiary designation on file. The surviving spouse's community property interest is a state law right that exists independently of the IRA beneficiary form.
Navigating the intersection of IRA beneficiary designations and California community property requires attention to the source of contributions, the nature of any property agreements between the spouses, and the coordination between the IRA beneficiary form and any wills, trusts, or community property agreements in place. Both a financial advisor and a California estate planning attorney are typically needed to address these dimensions together.
California community property law and its interaction with federal retirement account rules reflect the law as of the date this article was written. State and federal law in this area can change; consult a qualified California estate planning attorney for guidance specific to any particular situation.
How Coordinated Planning Addresses These Variables
The complexity in beneficiary designation planning is not primarily in filling out a form. It is in making sure the designations on each account are consistent with the rest of the estate plan, reflect the current family situation, account for the tax consequences facing different beneficiaries, and work alongside any trusts or other planning structures already in place.
For a married couple with a revocable living trust, the question of whether to name the trust or the surviving spouse as primary beneficiary on each IRA has different answers depending on the specific trust language, the estate tax exposure of the estate, the age and health of each spouse, and whether the couple has children from a prior relationship. There is no universal answer.
For a retiree with a substantial IRA who wants to pass assets to adult children while managing the tax compression caused by the 10-year rule, strategies such as multi-year Roth conversions during the retiree's lifetime may reduce the size of the taxable IRA that beneficiaries ultimately inherit, distributing the tax cost over years when the account owner may be in a more favorable bracket. This is one example of how beneficiary planning and lifetime income planning intersect: decisions made during the account owner's lifetime directly affect the tax outcomes facing the next generation.
For high earners in California with multiple retirement account types, the interaction between ERISA spousal consent requirements, California community property rights, and the trust provisions in an estate plan requires that the financial advisor, the estate planning attorney, and the tax professional are all working from a shared understanding of the overall plan.
Beneficiary designations are one of the areas where the gap between a document being filed and a plan being in place can be widest, and where that gap is often invisible until it is too late to address it.
