Direct answer: A beneficiary designation is a legal instruction filed with a financial institution that names who receives an account or policy at the owner's death. Beneficiary designations apply to IRAs, 401(k)s, 403(b)s, life insurance policies, annuities, and taxable brokerage accounts registered with a transfer-on-death designation. They override the will entirely: whatever the will says, the designated beneficiary receives the account. Primary beneficiaries inherit first; contingent beneficiaries inherit only if all primary beneficiaries have predeceased the owner. Per stirpes passes a deceased beneficiary's share to their descendants; per capita divides it among surviving beneficiaries.
Beneficiary Designations: What They Are and Why Investors Care
What Is a Beneficiary Designation?
A beneficiary designation is a written instruction that an account owner submits to a financial institution, insurance company, or retirement plan administrator. It specifies who receives the account balance or policy proceeds when the owner dies. The designation creates a direct contract between the account owner and the institution; it functions independently of the owner's will or trust.
The practical consequence: a beneficiary designation overrides the will entirely for any account that uses one. An investor who writes a will leaving everything equally to three children, but whose IRA names a single sibling as beneficiary from an old form, has effectively left the IRA to the sibling. The will has no authority over the IRA because the IRA transferred before the estate was even opened, directly to the designated beneficiary outside of any probate or estate administration process.
Which Accounts Use Beneficiary Designations?
Beneficiary designations apply to a specific set of account types:
- Individual Retirement Accounts (IRAs): traditional, Roth, SEP, and SIMPLE IRAs all require a designated beneficiary form filed with the IRA custodian.
- Employer-sponsored retirement plans: 401(k), 403(b), 457(b), and pension plans. These plans are governed by ERISA, which has its own rules; married participants in ERISA plans generally must name their spouse as primary beneficiary unless the spouse signs a written waiver.
- Life insurance policies: the named beneficiary receives the death benefit directly, income-tax-free, outside of probate.
- Annuities: the designated beneficiary receives the remaining contract value or death benefit according to the contract terms.
- Taxable brokerage accounts with TOD registration: a transfer-on-death registration allows a brokerage account to pass to the named beneficiary without probate, effectively giving a taxable account the same probate-avoidance benefit as a beneficiary designation.
- Bank accounts with POD designation: payable-on-death designations function identically for bank accounts.
Primary vs Contingent Beneficiaries
Most beneficiary designation forms allow naming both primary and contingent beneficiaries. Understanding how they interact is essential for ensuring the intended outcome.
Primary Beneficiaries
A primary beneficiary is the first in line to inherit. If any primary beneficiary is alive at the account owner's death, that beneficiary receives their designated share of the account. If multiple primary beneficiaries are named, each receives their specified percentage; the percentages must sum to 100%.
Contingent Beneficiaries
A contingent beneficiary (sometimes called a secondary beneficiary) inherits only if all primary beneficiaries have predeceased the account owner. Contingent beneficiaries provide an important safety net. Without a named contingent, if all primary beneficiaries die before the account owner and no new designation is filed, the account may pass to the estate by default, losing the direct-transfer benefit and potentially accelerating the distribution timeline for a retirement account.
Per Stirpes vs Per Capita Distribution
When naming multiple beneficiaries, the form typically allows the owner to specify per stirpes or per capita distribution. The choice determines what happens when a named beneficiary predeceases the account owner.
Per Stirpes
Per stirpes (Latin for "by the branch") distributes the deceased beneficiary's share to that beneficiary's own descendants, preserving the "branch" of the family. If a parent names three children per stirpes and one child predeceases the parent leaving two grandchildren, those grandchildren each receive half of their deceased parent's one-third share. The grandchildren inherit, not the two surviving siblings who receive only their own shares.
Per Capita
Per capita distributes the estate equally among all surviving named beneficiaries. If one child dies, the surviving two children each inherit half. The deceased child's own descendants receive nothing directly from the account. Per capita is simpler but may disinherit an entire branch of the family if a beneficiary predeceases the account owner.
Per stirpes is generally the preferred election for investors with children because it ensures that grandchildren are not disinherited if their parent dies before the account owner. It reflects the typical intent: to distribute wealth among family branches, not to advantage surviving branches at the expense of predeceased ones.
The SECURE Act and Inherited IRA Rules
The Setting Every Community Up for Retirement Enhancement (SECURE) Act of 2019 made the most significant changes to inherited IRA distribution rules in decades. For account owners whose accounts were inherited after December 31, 2019, most non-spouse beneficiaries can no longer take distributions over their lifetime. Instead, they must empty the account within 10 years of the original owner's death.
Eligible Designated Beneficiaries (Stretch Still Applies)
Five categories of beneficiaries, called "eligible designated beneficiaries," retained the ability to take life-expectancy distributions:
- The surviving spouse of the original owner
- Minor children of the original owner (until they reach the age of majority, then the 10-year rule applies)
- Disabled individuals (as defined under IRC section 72(m)(7))
- Chronically ill individuals
- Any individual not more than 10 years younger than the deceased account owner
Implications for Designation Strategy
The end of the stretch for most non-spouse beneficiaries changes the analysis for who should inherit a traditional IRA. A beneficiary in a high income-tax bracket who is forced to take all distributions within 10 years may pay substantial income tax on each distribution. Strategies include naming a spouse (who can roll over the IRA into their own account and defer further), naming younger beneficiaries in lower tax brackets, converting traditional IRA assets to Roth before death (so the inherited Roth IRA passes income-tax-free under the same 10-year rule), or naming a charity for the traditional IRA (charities pay no income tax on distributions).
Frequently Asked Questions
What is a beneficiary designation?
A beneficiary designation is a legal instruction filed directly with a financial institution, life insurer, or retirement plan administrator that names who receives the account or policy proceeds at the account owner's death. It is a contract between the account owner and the institution. Beneficiary designations control the transfer of IRAs, 401(k)s, 403(b)s, life insurance policies, annuities, and any taxable account registered with a transfer-on-death (TOD) or payable-on-death (POD) designation. Critically, a beneficiary designation overrides the will entirely for accounts that use them. If the will says 'everything to my children' but the IRA names a sibling as beneficiary, the sibling inherits the IRA.
What is the difference between per stirpes and per capita beneficiary designation?
Per stirpes distributes the share of a predeceased beneficiary to that beneficiary's descendants. If you name your three children per stirpes and one child dies before you leaving two grandchildren, those grandchildren split their parent's share equally. Per capita distributes the estate equally among all surviving members of the designated class. If one child dies under per capita, that child's share is divided equally among the remaining two surviving children, with nothing going to the deceased child's own children. Per stirpes is generally preferred for multi-generational families because it prevents grandchildren from being disinherited when a child predeceases the account owner.
How did the SECURE Act change inherited IRA rules?
The SECURE Act of 2019 eliminated the stretch IRA for most non-spouse beneficiaries. Before the SECURE Act, a non-spouse beneficiary could take required minimum distributions from an inherited IRA over their own life expectancy, stretching tax deferral over decades. After the SECURE Act, most non-spouse beneficiaries must distribute the entire inherited IRA balance within 10 years of the original owner's death. Eligible designated beneficiaries, including surviving spouses, minor children until the age of majority, disabled or chronically ill individuals, and beneficiaries not more than 10 years younger than the decedent, may still use life-expectancy distributions. The 10-year rule applies to both traditional and Roth inherited IRAs, though Roth distributions are income-tax-free.
