How to Split Retirement in Divorce: QDROs, IRAs, and Taxes

To split retirement accounts in divorce, you identify the marital portion of each account, decide whether to trade it against other assets or divide the account itself, and then file the correct paperwork with each plan: a Qualified Domestic Relations Order (QDRO) for employer plans like 401(k)s and pensions, and the divorce decree itself for IRAs. Retirement savings are often the largest marital asset after a home, and the wrong form or the wrong timing can trigger a tax bill or wipe out a share you were entitled to.

Figure Out the Marital Portion First

Only the part of a retirement account earned during the marriage is on the table. Contributions and growth from before the wedding, and in most states from after the date of separation, generally stay with the account holder.

For a 401(k), 403(b), or similar defined contribution plan, the math is straightforward. Ask the plan administrator in writing for the balance on the wedding date and the balance on the separation or filing date, depending on which your state uses. Subtract one from the other, then back out anything from a non-marital source, such as an inheritance that was rolled in.

Pensions are harder. A defined benefit pension pays a monthly check in retirement, so there is no single balance to point to. Actuaries value the marital share using a coverture formula: years of service during the marriage divided by total years of service, applied to the projected benefit. Plan on hiring a professional valuator for anything more than a simple account.

The valuation date matters more than people expect. If a 401(k) was worth $300,000 at separation and $240,000 by the time the decree is signed, whether the split runs off the earlier or later number changes what each spouse ends up with. Some states lock in the separation date, some use the filing date, and some let the judge pick. If markets move meaningfully between separation and the final order, ask your attorney whether the valuation date should be revisited.

Two Ways to Divide What’s Marital

Once you know the marital value, there are two basic approaches.

The Offset Method

One spouse keeps the whole retirement account, and the other takes assets of equal value: more home equity, cash, a taxable brokerage account. If the marital portion of a 401(k) is $200,000, one spouse might keep it while the other takes $200,000 in equity from the house.

This gives you a clean break with no continuing administrative link. The catch is that a dollar in a pretax 401(k) is not worth a dollar in home equity: the retirement dollar will be taxed on the way out, the equity dollar generally will not. Compare after-tax value, not sticker value.

Deferred Distribution

The account itself is split, and each person walks away with a designated share. This is standard for pensions and for cases without enough other assets to offset. It keeps administrative connections alive until benefits are paid, but it avoids the apples-to-oranges problem of the offset method.

QDROs for 401(k)s, Pensions, and Other Employer Plans

Employer-sponsored plans — 401(k)s, 403(b)s, pensions, profit-sharing plans — fall under ERISA, which generally forbids paying benefits to anyone but the participant. The one exception is a Qualified Domestic Relations Order. A QDRO tells the plan administrator to pay part of the participant’s benefit to an “alternate payee,” almost always the former spouse.

What the Order Must Say

Federal law requires a valid QDRO to state four things: the full legal names and last known addresses of the participant and each alternate payee; the exact dollar amount or percentage going to the alternate payee, or the formula for calculating it; the number of payments or the time period covered; and the name of each plan the order applies to.¹ Most administrators also ask for Social Security numbers to process the split, even though the statute doesn’t require them. The single biggest thing you can do to avoid rejection is to request the plan’s own model QDRO language and use it.

A QDRO also can’t do certain things. It can’t order the plan to pay a form of benefit the plan doesn’t offer, can’t require the plan to pay more than it actuarially owes, and can’t hand the alternate payee benefits already assigned to someone else under an earlier QDRO.²

Shared Payment vs. Separate Interest for Pensions

If you’re dividing a defined benefit pension, the QDRO has to pick a structure. Under a shared payment approach, the alternate payee receives a slice of each pension check once the participant retires and starts collecting. Payments stop if the participant dies, unless the order includes survivor protection. Under a separate interest approach, the alternate payee’s share is carved into an independent benefit they can start on their own schedule, regardless of when the participant retires.³ Separate interest gives the alternate payee more control, but not every plan allows it.

Don’t Forget Survivor Benefits

A pension QDRO should say what happens if either party dies, both before and after payments begin. Without specific language, a shared payment alternate payee can lose their entire interest if the participant dies first.

The key protection before retirement is the qualified preretirement survivor annuity (QPSA). If the QDRO designates the alternate payee as the participant’s spouse for QPSA purposes, they stay eligible for a survivor benefit even if the participant dies before retiring. Under a separate interest division, the carved-out benefit usually survives the participant’s death anyway, but the order should spell it out.⁴ If the QDRO is silent, the plan’s default rules apply, and those defaults often strip a former spouse of survivor rights the moment the divorce is final.

IRAs Don’t Need a QDRO

Traditional IRAs, Roth IRAs, SEP IRAs, and SIMPLE IRAs aren’t ERISA plans and don’t need a QDRO. They’re divided tax-free as long as the transfer is made under a divorce decree or written separation agreement, and the transferred piece becomes the receiving spouse’s own IRA from the transfer date forward.⁵

To move the money, give the IRA custodian a certified copy of the decree or agreement specifying the split. The custodian transfers the designated amount into a new IRA in the receiving spouse’s name. No separate court order.⁶

One trap: money you withdraw from an IRA received in divorce is still hit with the 10% early withdrawal penalty if you’re under 59½. The QDRO penalty exception explained below does not apply to IRAs.⁷

Military and Federal Pensions Use Different Orders

A regular QDRO won’t work for military retired pay or federal civilian retirement. If either spouse has one of these, plan for a separate process.

Military retirement is divided under the Uniformed Services Former Spouses’ Protection Act, which lets state courts treat military retired pay as marital property. The most that can be paid directly to a former spouse is 50% of the member’s disposable retired pay. For the Defense Finance and Accounting Service to send payments directly, the marriage has to have lasted at least 10 years overlapping at least 10 years of creditable service.⁸ Shorter marriages can still produce an award, but the member pays the former spouse directly rather than the military. The order must state the award as a fixed dollar figure or a percentage of disposable retired pay; vague formulas get rejected. The former spouse applies for direct payment with DD Form 2293 and a certified court order.⁹

Federal civilian benefits under CSRS or FERS are split through a Court Order Acceptable for Processing (COAP), filed with the Office of Personnel Management. Like a QDRO, a COAP has to meet specific requirements before OPM will pay anything to a former spouse.¹⁰

Taxes and the Early Withdrawal Penalty

How you split a retirement account decides who pays income tax and whether the 10% early withdrawal penalty applies.

When an alternate payee takes a distribution from a qualified employer plan under a QDRO, they report the payment as their own income and pay the tax. The participant owes nothing on that share. If the order instead sends money to a child or other dependent, the tax falls on the participant.¹¹

A QDRO distribution paid directly to a former spouse from a qualified employer plan escapes the 10% early withdrawal penalty even if the alternate payee is under 59½.⁷ The exception is a one-shot deal: it only covers the initial distribution from the employer plan. Roll the money into your own IRA and later pull it out before 59½, and the 10% penalty is back. If you need some cash right away and you’re under 59½, take that portion directly from the employer plan under the QDRO before rolling the rest.

An alternate payee who doesn’t need the cash can roll the QDRO distribution into their own IRA or another eligible employer plan with no tax due at the time. The same is true for IRA-to-IRA transfers made under a divorce decree.⁵

How the Paperwork Actually Moves

Employer Plans

The order matters. Do this before you file anything with the court:

Ask the plan administrator for their model QDRO language and their submission procedures.
Have the QDRO drafted, usually by an attorney or a QDRO preparation service, and send the draft to the administrator for pre-approval. They’ll flag language that doesn’t fit the plan.
Once the administrator is satisfied, submit it to the court for a judge’s signature.
Get a certified copy from the clerk (a small fee, varies by court) and send it to the plan administrator.
Wait. The administrator reviews the certified order, decides whether it qualifies, and then processes the split. During the review, the plan must segregate the amounts that would go to the alternate payee. Processing typically runs 30 to 90 days after the administrator has the certified order, longer for complex cases.¹²

IRAs

Send the IRA custodian a certified copy of the divorce decree or separation agreement specifying the split. The custodian moves the designated amount into an IRA in the receiving spouse’s name. No separate order, no taxable event.⁶

Mistakes That Cost People Their Share

Finalizing the divorce and never filing the QDRO. Until the plan administrator has a qualified order in hand, the alternate payee has no enforceable claim. If the participant withdraws money, changes beneficiaries, or dies in the meantime, the intended share can be gone.
Rolling QDRO money into an IRA before pulling out what you need. Once it’s in the IRA, the penalty exception is gone and any withdrawal before 59½ triggers the 10%.
Leaving survivor benefits out of a pension QDRO. Default plan rules often strip former spouses of survivor rights at divorce.
Filing the wrong instrument. A QDRO submitted for an IRA is wasted effort. A standard QDRO submitted for military retired pay or federal civilian retirement will be rejected; those systems need their own orders.
