What Happens to Your IRA, 401(k), and Retirement Accounts When You Die in New Jersey

Retirement accounts are often the largest single asset in a New Jersey family's estate. An IRA or 401(k) accumulated over a 30-year career can represent hundreds of thousands, or millions, of dollars. And yet these assets receive less careful attention in estate planning than almost any other part of the financial picture.

The reason is a fundamental misunderstanding about how retirement accounts work at death. Most people assume that their will governs their estate, all of it. It doesn't. Retirement accounts operate entirely outside the will, outside the trust, and outside the probate process. They pass directly to whoever is named on a single form: the beneficiary designation.

That form, often filled out decades ago, rarely reviewed, and almost never coordinated with the rest of the estate plan, controls the inheritance of the most valuable asset in the estate. And when it is wrong, misaligned, or outdated, the consequences can be severe: assets going to an ex-spouse, a deceased person, or the estate itself; massive income tax bills for heirs; and the loss of flexibility that a well-planned inheritance would have provided.

The direct answer: In New Jersey, retirement accounts (IRAs, 401(k)s, 403(b)s, pensions) do not go through probate. They pass directly to the named beneficiary regardless of what a will or trust says. Under the SECURE Act and SECURE 2.0, most non-spouse beneficiaries must fully distribute inherited retirement accounts within 10 years of the original owner's death. NJ inheritance tax may apply when retirement account proceeds pass to non-Class A beneficiaries. Beneficiary designations must be reviewed and coordinated with the overall estate plan regularly.

The Basics: How Retirement Accounts Pass at Death

Retirement accounts, IRAs, Roth IRAs, 401(k)s, 403(b)s, 457 plans, and most pension plans, are not probate assets. They pass by contract, not by will. When you opened the account and completed the beneficiary designation, you created a direct, binding contract between yourself, the account custodian, and your named beneficiary.

When you die, the account passes to that named beneficiary immediately, without going through the Surrogate's Court, without waiting for estate administration, and without being affected by anything your will says.

This means that if your will says "everything to my children equally" but your IRA names only your oldest child as beneficiary, your oldest child receives the entire IRA. The other children have no claim to it. The will's instruction is irrelevant to the retirement account.

It means that if you divorced 15 years ago but never updated your IRA beneficiary designation, and your ex-spouse is still named, your ex-spouse receives the IRA regardless of your current wishes, your current will, and any divorce decree. Federal law (ERISA) governs 401(k) beneficiary designations in ways that can override state divorce law, this is a particularly dangerous gap for families who went through divorce without legal counsel on retirement asset issues.

It means that the simple form you filled out when you started your job 30 years ago, probably without much thought, probably naming whoever seemed appropriate at the time, controls the inheritance of assets worth far more than you imagined when you signed it.

Primary vs. Contingent Beneficiaries, Why Both Matter

Every retirement account beneficiary designation has two tiers: primary and contingent.

The primary beneficiary receives the account at your death. If the primary beneficiary has predeceased you, the account passes to the contingent beneficiary, the backup.

If the primary beneficiary predeceases you and there is no contingent beneficiary named, the account typically defaults to your estate. This creates the "estate as beneficiary" problem discussed below, one of the most costly outcomes in retirement account inheritance.

When naming beneficiaries, the per stirpes vs. per capita designation matters for families with multiple children. A per stirpes designation means that if a child predeceases you, their share passes to their own children (your grandchildren) in equal shares. A per capita designation means the surviving named beneficiaries split the share equally: the deceased child's family receives nothing. For most families with children and grandchildren, per stirpes is the more intentional choice, but the right answer depends on the family's specific structure and wishes.

The "Estate as Beneficiary" Problem

Naming your estate as beneficiary on a retirement account, or failing to name anyone, which produces the same result, is one of the most consequential estate planning errors we see.

When the estate is the beneficiary of a retirement account, the account passes through probate. This creates several significant problems:

Loss of the 10-year distribution rule. Individual beneficiaries who inherit a retirement account generally have 10 years to distribute the account, with flexibility to choose when within those 10 years they take distributions, allowing them to time withdrawals to minimize income tax. When the estate is the beneficiary, this flexibility may be reduced or eliminated, depending on the decedent's age and required minimum distribution status.

Estate administration delay. The account cannot be distributed to heirs until the estate is administered through probate, which in New Jersey can take a year or more for complex estates.

NJ inheritance tax complications. When the account passes through the estate and then to beneficiaries, the inheritance tax analysis becomes more complex, potentially exposing amounts to tax that could have been avoided through direct beneficiary designations to exempt beneficiaries.

Income tax acceleration. Depending on the circumstances, the estate may be required to distribute the entire account within a compressed timeframe, generating large taxable income in a single year.

The solution is straightforward: always name a primary and contingent beneficiary. Never leave the beneficiary designation blank. Never name the estate as beneficiary unless you have a specific, attorney-advised reason to do so.

The SECURE 2.0 Act and the 10-Year Rule, What NJ Families Need to Know in 2026

The original SECURE Act, passed in 2019, fundamentally changed the rules for inherited retirement accounts. For most non-spouse beneficiaries, the ability to "stretch" distributions from an inherited IRA over their own lifetime, the so-called "stretch IRA", was eliminated. In its place: the 10-year rule.

Under the 10-year rule, most non-spouse beneficiaries who inherit a retirement account must fully distribute that account within 10 years of the original owner's death. There is no requirement to take distributions in any particular year within those 10 years, but the entire account must be emptied by the end of the 10th year.

SECURE 2.0, enacted in 2022, made further adjustments and clarifications. Importantly, the IRS has issued regulations clarifying that when the original account owner had already begun required minimum distributions (RMDs) before death, beneficiaries subject to the 10-year rule must also take annual RMDs within that 10-year period, not simply wait until year 10 to take everything.

Eligible designated beneficiaries, a specific category established by the SECURE Act, are not subject to the 10-year rule and retain more favorable distribution options. This category includes:

• Surviving spouses (who can roll the inherited account into their own IRA)
• Minor children of the deceased (until they reach the age of majority, at which point the 10-year rule begins)
• Disabled individuals (as defined under IRS rules)
• Chronically ill individuals
• Individuals not more than 10 years younger than the deceased

For a surviving spouse, the most valuable option remains the spousal rollover: rolling the inherited IRA into their own IRA, which restarts the RMD calculation based on the spouse's own age and pushes the distribution timeline forward.

The income tax impact: The 10-year rule has significant income tax implications for beneficiaries who are working-age adults. A 45-year-old who inherits a $500,000 IRA from a parent must distribute that entire account within 10 years, and those distributions are ordinary income. Depending on the beneficiary's tax bracket, distributing the account in years of high income could push a substantial portion into the highest tax brackets. Coordinating distributions across the 10-year window to minimize the overall tax burden requires thoughtful planning.

Naming a Trust as Beneficiary, When It Makes Sense and When It Doesn't

Naming a trust as the beneficiary of a retirement account is sometimes the right choice, but it introduces complexity that must be carefully managed.

Reasons to name a trust as beneficiary:

• Blended family protection: Ensuring that the IRA ultimately passes to children from a prior marriage, not to a surviving spouse who might redirect it.
• Spendthrift protection: Preventing a beneficiary who struggles with financial management from receiving a large lump sum.
• Special needs planning: Ensuring that an inherited IRA reaches a beneficiary with a disability without disqualifying them from SSI or Medicaid. (Note: this requires a very specifically drafted trust, not all special needs trusts qualify.)
• Minor beneficiaries: Controlling when and how minor beneficiaries receive IRA funds.

The trade-off: For a trust to be eligible for the 10-year rule rather than immediate distribution, it must meet IRS "see-through trust" requirements, it must be irrevocable at the owner's death, have identifiable beneficiaries who are individuals, have a copy on file with the custodian, and meet other technical requirements. If these requirements are not met, the account may need to be distributed within 5 years (if the owner died before RMDs began), a worse outcome than the 10-year rule.

A trust intended to receive retirement account assets must be drafted with specific attention to these IRS requirements. This is specialized planning that requires an attorney experienced in both estate planning and retirement account distribution rules.

NJ Inheritance Tax and Retirement Accounts

New Jersey's inheritance tax applies to retirement account proceeds paid to Class C or Class D beneficiaries, in addition to the federal and NJ income tax owed on the distributions.

Class A beneficiaries, spouses, children, grandchildren, and parents, are exempt from NJ inheritance tax. A parent who leaves an IRA to a child will generate income tax for that child on each distribution, but no NJ inheritance tax.

Class C beneficiaries, siblings and sons/daughters-in-law, pay NJ inheritance tax at rates from 11 to 16 percent on the value they receive, in addition to income tax on distributions. A sibling who inherits a $200,000 IRA faces both income tax on distributions over 10 years and NJ inheritance tax on the value received.

Class D beneficiaries, nieces, nephews, friends, and unmarried partners who don't qualify for the spousal exemption, pay NJ inheritance tax at 15 to 16 percent.

This double taxation (income tax + NJ inheritance tax) on retirement accounts passing to non-exempt beneficiaries is one of the more significant planning considerations for NJ families. Strategies to address it include routing IRA assets to Class A beneficiaries and directing other (non-IRA) assets to Class C or D beneficiaries, keeping the tax-efficient structure aligned with the most favorable beneficiary category.

The Annual Beneficiary Designation Review

Beneficiary designations should be reviewed every three years at minimum and immediately following any of these life events:

• Marriage or remarriage
• Divorce or separation
• Death of a named primary beneficiary
• Birth or adoption of a child or grandchild
• Significant change in the financial situation of a named beneficiary
• A named beneficiary develops a disability that would affect benefit eligibility
• A named beneficiary becomes a minor (through death of their parent)
• Relocation to a different state with different inheritance laws

The divorce trap deserves special attention. In New Jersey, state law revokes beneficiary designations on certain accounts at divorce. However, ERISA-governed plans, 401(k)s and similar employer-sponsored plans, are governed by federal law, which does not automatically revoke beneficiary designations at divorce. A divorced individual who never updated their 401(k) beneficiary designation may inadvertently leave that account to their ex-spouse, even if the divorce decree purported to address retirement assets.

After any divorce, every beneficiary designation on every retirement account should be reviewed and updated immediately.

Frequently Asked Questions

Q: Does an IRA go through probate in New Jersey? No. An IRA with a named beneficiary passes directly to that beneficiary outside of the probate process, regardless of what the will says. The beneficiary designation controls entirely. Only if the estate is named as beneficiary, or if no beneficiary is named, does the account potentially pass through probate.

Q: What are the inherited IRA rules in 2026? For most non-spouse beneficiaries, the 10-year rule applies: the entire inherited IRA must be distributed within 10 years of the original owner's death. Eligible designated beneficiaries (spouses, minor children of the deceased, disabled individuals, chronically ill individuals, and individuals within 10 years of age of the deceased) have more favorable options. Surviving spouses can roll an inherited IRA into their own IRA.

Q: Can I name a trust as IRA beneficiary? Yes, but this requires careful structuring to preserve favorable tax treatment. The trust must meet IRS "see-through trust" requirements to qualify for the 10-year rule. A trust intended to receive IRA assets must be drafted by an attorney experienced in retirement account distribution rules: a general estate planning trust may not qualify.

Q: What happens if I name my estate as IRA beneficiary? The IRA will pass through probate, losing the flexibility of the 10-year distribution rule and potentially requiring faster distributions. Estate administration delays mean heirs may wait a year or more to receive the account. NJ inheritance tax and income tax analysis becomes more complex. Naming the estate as beneficiary is almost always a worse outcome than naming individual beneficiaries or a properly structured trust.

Q: What is the 10-year rule for inherited IRAs? The 10-year rule, established by the SECURE Act in 2019, requires most non-spouse beneficiaries to fully distribute an inherited retirement account within 10 years of the original owner's death. There is no annual distribution requirement within those 10 years (unless the original owner had already begun RMDs, in which case annual distributions are required within the 10-year window). The entire account must be distributed by the end of year 10.

Q: Does NJ inheritance tax apply to retirement account distributions? Yes, for Class C and Class D beneficiaries. NJ inheritance tax applies to the value of retirement account proceeds received by non-exempt beneficiaries, in addition to the income tax those beneficiaries owe on distributions. Class A beneficiaries (spouses, children, grandchildren, parents) are exempt from NJ inheritance tax.
