Inherited IRA in Divorce: Does the SECURE Act 10-Year Clock Reset for the Ex-Spouse?

The legal trap: the IRC § 408(d)(6) exception does NOT extend to inherited IRAs

Most attorneys handling divorce assume any IRA can be split tax-free under IRC § 408(d)(6). For an owner’s own Traditional or Roth IRA, that’s correct — the divorce-incident transfer rule allows trustee-to-trustee movement to the ex-spouse without tax. For an inherited IRA, the rule does not apply.

The IRS position, confirmed in multiple private letter rulings (PLR 200646025 and PLR 201025079) and reflected in the 2024 final SECURE Act regulations at 26 CFR § 1.401(a)(9)-5, is that an inherited IRA is a non-spousal beneficiary asset already in mandatory distribution mode. The beneficiary designation is established at the original decedent’s death and cannot be retitled or transferred to a third party without triggering the entire account as a taxable distribution to the named beneficiary.

Practically, this means: an inherited IRA cannot be split in divorce. It stays with the original beneficiary spouse. The asset’s value is offset against other marital property, but the IRA itself is non-transferable.

Why the SECURE Act 10-year clock cannot reset

The SECURE Act of 2019 imposed a 10-year drain rule on most non-spouse beneficiaries of inherited IRAs (IRC § 401(a)(9)(H)). The 10-year clock runs from December 31 of the year following the original decedent’s death. By the end of year 10, the account must be empty.

Critically, the 10-year clock is tied to the death of the original IRA owner — not to any later event involving the beneficiary. The 2024 final regulations explicitly address what happens when a beneficiary dies during the 10-year period: a successor beneficiary inherits, but the original 10-year clock continues running. There is no reset.

By logical extension, if an inherited IRA could somehow be transferred to an ex-spouse in divorce (it cannot), the 10-year clock would still run from the original decedent’s death date. The ex-spouse would not get a fresh 10-year window. They would inherit whatever fraction of the clock remained.

Since the transfer itself is impermissible, the question becomes academic — but the principle matters for understanding why offset negotiations apply a tax discount based on the remaining clock window held by the original beneficiary.

Worked example: $500K inherited IRA in year 6 of the 10-year clock

Consider a Phoenix couple ending an 18-year marriage. The wife inherited a $500,000 Traditional IRA from her father in 2020. As of 2026, she is in year 6 of the SECURE 10-year clock. She has taken $200K in distributions over the first 6 years (averaging $33K per year), and the remaining balance is $350K (after market growth offsetting distributions). She must drain the remaining $350K by December 31, 2030.

The wife’s ordinary-income tax bracket during the next 4 years averages 24%. The present after-tax value of the remaining $350K, distributed evenly over 4 years and taxed at 24% federal + 4.5% Arizona state = 28.5% combined, is approximately:

• $350,000 × (1 − 28.5%) = $250,250 after-tax (undiscounted)
• Applying a 4% present-value discount over the 4-year payout: approximately $232,000

The marital balance sheet credits the wife with $232,000 for the inherited IRA — not the $350K gross balance. The husband’s offset comes from other marital assets (joint brokerage, home equity, his own 401(k) via QDRO), reduced by $232K compared to a 50/50 gross-value split.

What happens if you ignore the rule and try to transfer the inherited IRA

If the wife attempted to transfer half of the inherited IRA ($175K) to the husband as part of the property settlement, the IRS would treat the “transfer” as a deemed full distribution of the inherited IRA to the wife in the year of transfer:

• The entire $350K inherited IRA balance is treated as distributed to the wife.
• $350K of ordinary income added to her 2026 return.
• Combined federal + Arizona state tax: approximately 32% effective — $112,000 tax bill.
• The $175K “transferred” to the husband is treated as a property settlement payment under IRC § 1041 (tax-free between spouses), but the husband receives cash, not an inherited IRA — future growth is taxable.
• The wife ends up with $63K remaining after tax ($350K − $112K tax − $175K to husband). She destroyed $169K of tax-deferred growth potential on the half she would have continued to hold.

The error compounds: the inherited IRA loses its tax shelter, the wife absorbs an entire year’s worth of distribution income in one tax year (creating bracket creep into 32% or higher), and the husband’s “share” is now ordinary-taxed cash. Net to the family: roughly $150K destroyed versus the offset approach.

Surviving-spouse exception: the one case where the rule looks different

One scenario creates apparent ambiguity: a surviving spouse who inherited an IRA from a deceased first spouse, then divorces in a subsequent marriage. The surviving spouse has the option under IRC § 408(a)(6) and 26 CFR § 1.408-8 to roll the inherited IRA into their own IRA, treating it as if it had always been theirs.

Once rolled into the surviving spouse’s own IRA, the asset loses its “inherited” character. It is now governed by ordinary owner-IRA rules: subject to the survivor’s own age-59½ rules, their own RMD age (73 or 75 under SECURE 2.0), and — critically — the IRC § 408(d)(6) divorce-incident transfer rule applies. In a subsequent divorce, the rolled-over IRA can be split tax-free.

This creates a real planning opportunity. A surviving spouse contemplating remarriage should consider whether to keep the asset as an inherited IRA (subject to the SECURE 10-year drain) or roll it into their own IRA (which preserves owner-IRA flexibility, including divorce divisibility, but submits to the survivor’s RMD rules). For high-net-worth survivors who expect to remarry, the roll-as-own election preserves optionality.

For a non-spouse beneficiary (child, sibling, friend of the decedent), this option does not exist. The inherited IRA remains inherited forever and cannot be retitled.

Community property vs. equitable distribution: the state-law overlay

Even before reaching the IRC § 408(d)(6) federal-tax question, state property-classification rules determine whether the inherited IRA is divisible at all.

In the 9 community-property states (California, Arizona, Idaho, Louisiana, Nevada, New Mexico, Texas, Washington, Wisconsin), inheritances are statutorily separate property of the recipient. California Family Code § 770(a)(2) explicitly provides: “Separate property of a married person includes all of the following: (2) All property acquired by the person after marriage by gift, bequest, devise, or descent.” Texas Family Code § 3.001(2) provides the same treatment. An inherited IRA received during marriage in a community-property state is generally entirely the recipient’s separate property — not subject to division at all.

In the 41 equitable-distribution states, inheritances are typically treated as separate property unless commingled, but the state-by-state nuances vary. New York Domestic Relations Law § 236(B)(1)(d)(1) treats inheritances as separate property; Pennsylvania’s 23 Pa.C.S. § 3501 reaches the same outcome through different statutory language. Massachusetts and a handful of other states allow courts more discretion to consider all assets in equitable division, but the strong starting presumption is separate-property treatment.

The practical implication: in California, Texas, or Washington, an inherited IRA may not be divisible at all — the federal-tax transferability question becomes moot because the asset is not part of the marital estate to begin with. In Massachusetts or Connecticut, the asset may be considered for equitable division if commingling or family-expense use occurred.

Commingling: how separate property becomes marital

The strong separate-property presumption on inherited assets can be defeated by commingling. If the beneficiary spouse:

• Took distributions from the inherited IRA and deposited them in a joint checking account used for joint expenses,
• Used inherited IRA distributions to pay down the joint mortgage,
• Made joint contributions or transfers between the inherited IRA and any joint-titled account,
• Treated the inherited IRA as a joint marital asset in financial statements or tax returns,

— the other spouse can argue transmutation. The inherited IRA may then be treated as marital property in whole or in part. Tracing the inheritance source and documenting the segregation of distributions becomes essential. Forensic CPAs in high-asset divorces routinely produce inheritance-tracing reports to defend the separate-property characterization.

The protective practice: any beneficiary who anticipates a possible future divorce should keep the inherited IRA distinctly titled, take distributions into a separate account titled solely in the beneficiary’s name, and avoid using inherited-IRA proceeds for joint marital expenses. The cleaner the separation, the stronger the separate-property defense.

Successor beneficiary updates: the post-divorce 90-day imperative

Every inherited IRA has a successor-beneficiary designation. If the original beneficiary spouse dies during the 10-year period, the successor inherits the remainder — subject to the original 10-year clock continuation. Most divorcing beneficiaries forget that the successor-beneficiary form on their inherited IRA may still name their soon-to-be-ex-spouse.

Within 90 days of the final decree, the inherited IRA holder should:

• Request the current successor-beneficiary designation from the IRA custodian.
• File an updated form removing the ex-spouse and naming children, a trust, or other intended beneficiaries.
• Verify the change is reflected on the custodian’s records within 30 days.
• Keep a copy of the executed form with estate-planning documents.

Failure to update can result in the ex-spouse inheriting the remaining inherited IRA balance — an outcome the decedent almost certainly did not intend. Unlike retirement plan beneficiaries (where the federal Retirement Equity Act may protect a surviving current spouse), IRA successor beneficiaries are governed entirely by the IRS-filed designation. The decree does not override the form.

Negotiation framework for inherited IRA offsets

When one spouse holds an inherited IRA and the other is entitled to a share of the marital estate, the negotiation typically proceeds in three steps:

1. Establish the property characterization: separate (community-property state, no commingling), marital (commingling demonstrated), or partial (some commingling, some traced separate). This determines whether any offset is owed at all.
2. Calculate the after-tax present value: gross balance, expected distribution timing under the remaining 10-year clock, the beneficiary’s marginal tax rate during those years, and a present-value discount. A 4-year remaining clock at 24% federal + state tax with a 4% discount produces approximately 65–70% of gross balance as fair after-tax value.
3. Allocate offsetting marital assets: cash, brokerage, home equity, and the non-inherited portion of the holder’s own retirement accounts can be reallocated to the non-holding spouse to balance the inherited IRA value. IRC § 1041 governs these transfers as tax-free between spouses incident to divorce.

For high-asset divorces with inherited IRAs above $1M, retaining a forensic CPA to construct the after-tax valuation and a divorce financial analyst (CDFA®) to model the offset scenarios is standard practice. The cost ($5K–$15K) typically produces 6- to 7-figure swings in settlement outcomes by getting the valuation right.

Key takeaways

• An inherited IRA cannot be transferred to an ex-spouse in divorce. IRC § 408(d)(6) does not apply; the asset stays with the original beneficiary.
• The SECURE Act 10-year clock does not reset because the inherited IRA cannot be retitled. Any attempted transfer is a deemed full distribution to the original beneficiary — a six-figure tax error.
• In community-property states, inheritances are statutorily separate property and may not be divisible at all. In equitable-distribution states, separate-property status holds unless commingling is shown.
• The negotiation mechanism is offset: the inherited IRA stays with the holder, valued at after-tax present value (typically 65–70% of gross), with other marital assets reallocated to the non-holding spouse.
• A surviving spouse who rolled an inherited IRA into their own IRA can divide it normally under IRC § 408(d)(6) in a subsequent divorce — an exception that only applies to the spouse-inherited-from-deceased-spouse path.
• Update the successor beneficiary on the inherited IRA within 90 days of the decree. The named beneficiary controls regardless of the decree language.
