How to Divide an IRA in a Divorce

IRAs are among the most commonly mishandled assets in divorce. The most frequent mistake: treating them like a 401(k) and trying to split them with a QDRO. That's the wrong tool. IRAs have their own set of rules — rules that are actually simpler in some ways, but easy to get wrong in ways that trigger an unnecessary tax bill.

This article explains how the IRA transfer process works, the important differences between traditional and Roth IRAs in a settlement, and the mistakes most likely to cost you money.

IRAs vs. 401(k)s: The Key Difference

When dividing an employer-sponsored retirement plan like a 401(k), 403(b), or pension, the law requires a specific court order called a Qualified Domestic Relations Order (QDRO). The QDRO instructs the plan administrator how to divide the account and allows the transfer to happen without triggering taxes or early withdrawal penalties.

IRAs don't work that way. They're individual accounts — not employer plans — so ERISA law and the QDRO process don't apply. Instead, the Internal Revenue Code has its own provision: IRC § 408(d)(6), which governs transfers incident to divorce.

The practical difference: you don't need a separately drafted QDRO for an IRA. The divorce decree or written separation agreement itself is typically sufficient authorization, as long as it specifically names the IRA, the amount or percentage to be transferred, and authorizes the transfer. Once that document exists, the account holder contacts the IRA custodian (the brokerage or bank holding the account) and requests the transfer.

What Portion of an IRA Is Marital Property?

In most states, assets accumulated during the marriage are considered marital property — subject to division. Assets brought into the marriage, or inherited during the marriage, may be separate property not subject to division. IRAs follow the same general rule.

If one spouse opened an IRA before the marriage and continued contributing during the marriage, only the marital portion — contributions made and growth accumulated after the wedding — is typically subject to division. The pre-marital balance may be treated as separate property, depending on the state and how clearly it can be traced.

In practice, tracing the pre-marital portion can be complicated if the account has been active for many years and funds have been commingled. Some states use a formula based on the balance at the date of marriage versus the date of separation. Others rely on account statements going back to the wedding date. If the IRA has been active since before the marriage and the balances are large, working with a financial professional to document the separate property portion is often worth the effort.

If both spouses have IRAs of roughly equal value from the same time period, they may agree to each keep their own account — no transfer needed — if the overall settlement is otherwise balanced.

How the Transfer Process Actually Works

Once the divorce is finalized (or sometimes as part of a separation agreement), dividing an IRA involves four practical steps.

Step 1 — The divorce decree or separation agreement must authorize the transfer specifically. The document should name the IRA by account number (or sufficient description), state the amount or percentage to be transferred, and explicitly authorize the transfer under IRC § 408(d)(6). Vague language like "retirement accounts to be divided equally" has caused problems when custodians ask for more specifics.

Step 2 — The receiving spouse opens their own IRA. The funds must go into an IRA in the receiving spouse's name — not into a joint account, not into a brokerage account, not handed over as cash. The custodian receiving the funds will require the new account to be established before the transfer can occur.

Step 3 — The account holder submits a transfer request to the IRA custodian. Most major custodians (Fidelity, Vanguard, Schwab, etc.) have a specific form for divorce-related IRA transfers. The form will typically require a certified copy of the divorce decree or separation agreement. Processing time varies — expect anywhere from a few days to a few weeks.

Step 4 — The custodian moves the funds directly. Once approved, the agreed amount or percentage is transferred institution-to-institution. No taxes, no penalties. The receiving spouse now owns that portion as their own IRA.

Traditional IRA vs. Roth IRA — Why It Matters in Settlement

One of the most common settlement mistakes is treating a dollar in a traditional IRA as equivalent to a dollar in a Roth IRA. They're not the same.

A traditional IRA holds pre-tax dollars. Every dollar contributed was deducted from income when it went in (or was never taxed for non-deductible contributions). When money comes out in retirement, it's taxed as ordinary income. The balance you see in the account is not the balance you actually keep.

A Roth IRA holds after-tax dollars. Contributions were made from money already taxed. Qualified withdrawals in retirement — including all growth — are tax-free. The balance you see is closer to what you'll actually keep.

Comparing these accounts at face value in a settlement may disadvantage the spouse who receives the traditional IRA. A financial planner or CDFA (Certified Divorce Financial Analyst) can help calculate the after-tax value of each account, factoring in expected tax rates in retirement and projected years of growth remaining.

SIMPLE IRAs: A Special Rule

SIMPLE IRAs — offered by small employers — have a restriction worth knowing: any distribution or transfer within the first two years of participation may trigger an additional 25% penalty tax, rather than the standard 10%. If the IRA being divided is a SIMPLE IRA and the account was opened less than two years ago, this rule may affect how the transfer is handled. The same tax-free transfer incident to divorce rules apply, but the two-year window affects the penalty exposure if funds are ever later withdrawn early by the receiving spouse.

What Happens If You Withdraw Instead of Transfer

This bears repeating because it's the most costly mistake. If the IRA owner withdraws money and gives the cash to their spouse — even with the intention of being fair and dividing the account — the IRS treats the withdrawal as a taxable distribution to the account owner, not a transfer to the spouse.

For a traditional IRA, the full withdrawal amount is added to the account owner's taxable income for the year. If the account owner is under age 59½, a 10% early withdrawal penalty may apply on top of the income tax. Depending on the account size and the account owner's tax bracket, this mistake can cost tens of thousands of dollars in unnecessary taxes.

The receiving spouse cannot contribute that cash to their own IRA either — it doesn't count as an IRA contribution in the year of receipt, and IRA contribution limits apply to new contributions separately.

Inherited IRAs in Divorce

If either spouse has an inherited IRA — one they received from a deceased parent or other non-spouse beneficiary — the rules are more complicated. Inherited IRAs are generally considered separate property in most states, since they came from an inheritance. They also have their own required distribution rules that differ from regular IRAs.

If an inherited IRA does need to be divided, the transfer rules under IRC § 408(d)(6) still apply — but the receiving spouse takes the funds as a beneficiary, not as an IRA owner in the traditional sense. The required minimum distribution schedule of the original inherited IRA typically carries over. A financial advisor familiar with inherited IRA rules is particularly useful here.

Checklist Before You Transfer

Before contacting the IRA custodian, work through these steps to avoid delays and errors. The divorce decree or separation agreement should clearly name the account(s) being divided, specify the exact amount or percentage (not just "half"), and explicitly reference the transfer incident to divorce. The receiving spouse should have their own IRA account open and ready to receive funds. Both parties should have a copy of the certified divorce decree. And the account owner should contact the custodian before submitting paperwork — each institution has its own form and process, and knowing those requirements in advance prevents the transfer from being rejected and having to start over.
