IRA Transfer Incident to Divorce: How to Split an IRA Tax-Free

Splitting an IRA during divorce is one of the few times you can move retirement money between two people with zero tax and zero penalty. Done correctly — using what the IRS calls a transfer incident to divorce under IRC §408(d)(6) — the full amount transfers from one IRA to another without either party owing a dollar in tax, even if both spouses are under 59½. Done wrong, the distributing spouse reports the full distributed amount as ordinary income, owes a 10% early withdrawal penalty on top of that, and can only roll over whatever is left after taxes are paid.

The difference between these two outcomes is almost entirely in how your divorce decree is written — before you sign it.

How an IRA Transfer Incident to Divorce Works

The mechanism is straightforward in principle. IRC §408(d)(6) creates a specific exception to the normal IRA distribution rules. Under this exception, a transfer of IRA funds between divorcing spouses is not treated as a taxable distribution, provided two conditions are met:

1. The transfer is made pursuant to a divorce decree or written separation agreement that is incident to a divorce.
2. The transfer is a direct custodian-to-custodian transfer — meaning the money moves from one IRA directly to another IRA without passing through either spouse's hands.

When both conditions are satisfied, the IRS treats the transaction as if the receiving spouse always owned that portion of the IRA. No withholding occurs. No 1099-R is issued for the transferred amount. No 10% early withdrawal penalty applies, regardless of age. The transfer is invisible to the tax system.

The receiving spouse opens a new IRA in their own name at whatever custodian they choose — their own bank, brokerage, or financial institution. The transferred funds are deposited directly into that new account. From that point forward, the IRA belongs entirely to the receiving spouse under standard IRA rules.

The Wrong Way to Split an IRA — and Why It's Costly

The costly mistake happens when divorcing spouses attempt to "split" an IRA informally — one spouse takes a cash distribution from the IRA and hands part of the money to the other.

Here is what actually happens in that scenario:

The distributing spouse (the one whose IRA it is) has just taken a withdrawal. The full distributed amount is reported as ordinary income on their federal tax return for the year. If they're under 59½, a 10% early withdrawal penalty applies to the full amount. The distributing spouse cannot "undo" this by giving the cash to their ex-spouse.

To put numbers to it: on a $100,000 IRA distributed as cash, a person in the 32% federal tax bracket who is under 59½ would owe approximately $32,000 in federal income tax plus $10,000 in early withdrawal penalty — $42,000 gone before a dollar reaches the other spouse. And because the distributing spouse received the cash, they can only roll over what they actually have left, which is far less than the original $100,000.

The receiving spouse, meanwhile, did not receive funds from an IRA — they received a cash gift from their ex-spouse. That money has no special rollover treatment. If they attempt to contribute it to their own IRA, it counts against their annual contribution limit, which for 2026 is $7,000 ($8,000 if 50 or older). Most or all of the money cannot get into an IRA at all.

The entire retirement account's tax-sheltered status is effectively destroyed. This is not a recoverable error.

What Your Divorce Decree Needs to Say

The transfer incident to divorce mechanism lives or dies on the language in your divorce decree. The decree (or the marital settlement agreement incorporated into it) must specifically authorize the transfer in terms that invoke IRC §408(d)(6) and direct a custodian-to-custodian transfer.

The language should include:

• A reference to IRC §408(d)(6) or the phrase "transfer incident to divorce"
• Identification of the specific IRA account (account holder's name, financial institution, and ideally the last four digits of the account number)
• The amount or percentage to be transferred
• A direction that the transfer be made by direct custodian-to-custodian transfer to an IRA established by the receiving spouse

A bare-minimum version of this language looks like: "Pursuant to IRC §408(d)(6), [Spouse A] is hereby ordered to transfer [dollar amount / percentage] of [IRA account description] by direct custodian-to-custodian transfer to an IRA established in the name of [Spouse B]."

Both spouses should verify that this language appears in the decree before signing it. A decree that simply says "Spouse B is awarded $X from Spouse A's IRA" without the custodian-to-custodian instruction creates ambiguity about how the transfer is to be executed — and ambiguity often resolves in the direction of a taxable distribution.

Once the decree is signed, the receiving spouse contacts the IRA custodian, provides a copy of the relevant decree provision, and opens a new IRA for the funds to transfer into. The originating custodian moves the funds directly, with no withholding.

IRAs vs. 401(k)s — Different Rules, Different Instruments

The tax-free transfer treatment described in this post applies to IRAs only. Employer-sponsored retirement plans — 401(k)s, 403(b)s, corporate pensions — are governed by ERISA, federal law that predates IRC §408(d)(6) and operates completely differently.

To divide a 401(k) or pension in a divorce, you need a Qualified Domestic Relations Order (QDRO). A QDRO is a separate court order — not just a provision in your divorce decree — that must be drafted to comply with the specific plan's requirements, reviewed and pre-approved by the plan administrator before being signed by the judge, and then served on the plan administrator after it is signed. The plan administrator then directs the plan to segregate the alternate payee's share.

The QDRO process involves more steps, more time, and typically more cost. Drafting services for a QDRO run several hundred dollars or more. See (/blog/split-retirement-accounts-nevada-divorce) for a full walkthrough of how the QDRO process works in Nevada.

The practical takeaway: if both IRA and 401(k) assets are being divided in your divorce, they require two separate instruments. The decree handles the IRA transfer. The QDRO handles the 401(k). Do not submit a divorce decree to a 401(k) plan administrator as a substitute for a QDRO — the plan administrator will reject it, and the division will not be processed.

Nevada PERS (the state's public employee pension system) uses yet another instrument: a PERS-compliant division order using the coverture formula under NRS 125.155. It is neither a QDRO nor a simple decree provision.

After the Transfer — What to Know About Your New IRA

Once the custodian-to-custodian transfer is complete, the receiving spouse owns a fully independent IRA. A few things to know about it:

It follows standard IRA rules. Required minimum distributions (RMDs) begin at age 73. Withdrawals before 59½ are subject to ordinary income tax and the 10% early withdrawal penalty, unless an exception applies — the same rules that govern any IRA.

Investment control is immediate. The receiving spouse chooses how the funds are invested from the moment the transfer is complete. There's no waiting period, no restriction tied to the originating account's investment choices.

The transfer does not count as a contribution. The transferred amount does not count toward the annual IRA contribution limit ($7,000 for 2026, $8,000 if 50 or older). It is treated as a rollover of existing retirement assets, not a new contribution.

Traditional vs. Roth matters. If the originating IRA is a traditional IRA, the transferred funds go into a traditional IRA for the receiving spouse. If it's a Roth IRA, the funds go into a Roth IRA. The tax character of the account follows the transfer. This affects the receiving spouse's long-term tax planning: traditional IRA withdrawals in retirement are taxed as ordinary income; qualified Roth withdrawals are tax-free.

Keep the documentation. Retain a copy of the decree, the custodian's confirmation of the direct transfer, and the new account statement showing the opening balance. This documentation is the evidence that the transfer was done correctly if the IRS ever questions it.
