How Dividing Retirement Accounts in Divorce Actually Works

Dividing retirement accounts in divorce uses two tools: a qualified domestic relations order (QDRO) for employer plans such as a 401(k) or pension, and a transfer incident to divorce for IRAs. The 10% early-distribution exception for a former spouse applies only under a QDRO (IRS Topic No. 558).

For many couples, retirement accounts are among the largest assets in a divorce. In the Federal Reserve’s 2022 Survey of Consumer Finances, 54.3% of families held a retirement account, and the median balance among those families was $86,900, against $323,200 for a primary residence among homeowners. Source: Federal Reserve, Survey of Consumer Finances 2022. The rules for splitting them are federal, detailed and unforgiving of shortcuts. This guide covers which legal instrument divides which account, what each one must contain, the tax traps, pensions and survivor benefits, government plans, and timing.

Which tool divides which retirement account?

The first question is not how much each spouse receives. It is which instrument moves the money, because using the wrong one can leave the division unexecuted or turn it into a taxable withdrawal.

The decree states what each spouse is entitled to. For an employer plan, it does not by itself move a dollar. The Department of Labor is explicit that retirement plans “are neither permitted nor required to follow the terms of domestic relations orders purporting to assign retirement benefits unless they are QDROs.” Source: U.S. Department of Labor QDRO guide.

What must a QDRO contain?

A QDRO is a domestic relations order that creates or recognizes an alternate payee’s right to receive all or part of a participant’s benefits under a plan. Under 26 U.S.C. § 414(p)(2), it must clearly specify four things. Source: 26 U.S.C. § 414 (Cornell LII).

• The name and last known mailing address of the participant and of each alternate payee.
• The amount or percentage of the participant’s benefits to be paid to each alternate payee, or the way that amount or percentage is to be determined.
• The number of payments or the period the order covers.
• Each plan to which the order applies.

It also cannot ask the plan for something the plan does not offer. Section 414(p)(3)(A) requires that the order “does not require a plan to provide any type or form of benefit, or any option, not otherwise provided under the plan”. The order also cannot require increased benefits or reassign benefits already awarded to another alternate payee under an earlier QDRO. Source: 26 U.S.C. § 414 (Cornell LII).

The plan decides whether an order qualifies. Each plan must have written procedures, must notify the participant and alternate payee when it receives an order, and must determine qualification “within a reasonable period”. While that determination is pending, the administrator must separately account for amounts that would be payable to the alternate payee, for up to 18 months. Source: 26 U.S.C. § 414 (Cornell LII). Many plans will review a draft order before it goes to the judge, and some publish model language. Starting from the plan’s own model, where one exists, tends to reduce rejections.

Defined contribution plans: a dollar amount or a percentage

For a 401(k) or 403(b), the order typically assigns a fixed dollar amount or a percentage of the account as of a stated date. Two drafting details move real money: whether investment gains and losses between that date and the actual segregation are included, and how any outstanding plan loan is treated. The settlement should state both, and the order should match the settlement.

How are IRAs divided in divorce?

IRAs do not use a QDRO. They are divided by a transfer made under the divorce decree or a written instrument incident to it:

Source: 26 U.S.C. § 408 (Cornell LII). IRS Publication 504 confirms that from the date of the transfer, the interest is treated as the receiving spouse’s IRA. Source: IRS Publication 504, Divorced or Separated Individuals. Custodians generally process this as a direct transfer to an IRA in the receiving spouse’s name, on their own forms, with a copy of the decree.

The common mistake is the account owner withdrawing cash and handing it over. That is not a transfer under the decree. It is a distribution to the owner, and the IRS states that taxable IRA distributions “are wholly taxable to the spouse (or RDP) whose name is on the account”, who is also liable for any penalties and additional taxes. Source: IRS Publication 555, Community Property.

Does the 10% early withdrawal tax apply to a QDRO?

Distributions before age 59½ are generally subject to a 10% additional tax on the taxable portion. Source: IRS Topic No. 558. One exception exists for divorce, and it is narrower than many people assume:

Source: 26 U.S.C. § 72 (Cornell LII). Read together: cash paid to a former spouse directly from an employer plan under a QDRO avoids the 10% additional tax, though it is still ordinary income. Cash withdrawn from an IRA does not get that exception, even if the IRA was funded by a divorce transfer. IRS Topic No. 558 lists the QDRO exception among those that apply “to distributions from a qualified plan other than an IRA.” Source: IRS Topic No. 558.

Rollover or cash: the order of operations

A former spouse who receives a QDRO distribution can roll it over tax-free, as if they were the employee. Source: IRS Retirement Topics: QDRO. If the distribution is paid to them instead, the plan must withhold 20% for federal income tax, even if they intend to roll it over; a direct rollover to another plan or IRA avoids the withholding, and any amount not rolled over within 60 days is taxable. Source: IRS Publication 575, Pension and Annuity Income.

Illustrative example, hypothetical figures: a 45-year-old alternate payee is awarded $200,000 from a former spouse’s 401(k) under a QDRO and needs $50,000 for a home down payment. Option A: take $50,000 in cash from the plan and directly roll $150,000 to an IRA. The $50,000 is ordinary income, the plan withholds $10,000 (20%), and the 10% additional tax does not apply because the payment was made under a QDRO. Option B: roll all $200,000 to an IRA first, then withdraw $50,000. The same $50,000 is ordinary income, and because it now comes from an IRA, the 10% additional tax generally applies, adding $5,000. Same money, same person, different sequence. Whether cash is needed at all, and how much, is a question for your tax professional and your financial plan.

How is a pension divided in divorce?

A defined benefit pension promises a monthly income, not an account balance, so it is divided differently. Two federal approaches exist, described by the Department of Labor:

• Shared payment: the order splits “the actual benefit payments made with respect to a participant”, and the alternate payee “will not receive any payments unless the participant receives a payment or is already in pay status.”
• Separate interest: the order divides “the participant’s retirement benefit (rather than just the payments) into two separate portions”, giving the alternate payee a right to be paid at a time and in a form different from the participant’s.

Source: U.S. Department of Labor QDRO guide. Under 26 U.S.C. § 414(p)(4), an order can require payments to an alternate payee to begin at the participant’s earliest retirement age, even if the participant is still working. Source: 26 U.S.C. § 414 (Cornell LII).

The coverture fraction

Because only the part of a pension earned during the marriage is usually marital, courts commonly apply a time-based fraction: months of plan service during the marriage divided by total months of service. The IRS uses the same logic for tax purposes in community property states, where a civil service annuity is split between community and separate income based on service during the marriage. Source: IRS Publication 555, Community Property. The exact formula, and whether the benefit is measured at divorce or at retirement, is state law.

Illustrative example, hypothetical figures: a participant retires with 30 years of service, 15 of them during the marriage, and a benefit of $4,000 a month. The marital fraction is 15/30, or 50%, so the marital portion is $2,000 a month. If the order awards the alternate payee half of the marital portion, they receive $1,000 a month. If the order instead measures the benefit at the divorce date, the alternate payee’s share excludes raises earned after the divorce. The two methods can produce materially different lifetime values.

Survivor benefits

A share of a pension paid as a shared payment can stop when the participant dies. The protection is survivor coverage, and it must be in the order. Under 26 U.S.C. § 414(p)(5), to the extent a QDRO provides, a former spouse is treated as the surviving spouse for survivor annuity purposes. Source: 26 U.S.C. § 414 (Cornell LII). The Department of Labor adds that where a QDRO does this, “any subsequent spouse of the participant cannot be treated as the participant’s surviving spouse.” Source: U.S. Department of Labor QDRO guide. Survivor coverage usually reduces the monthly benefit, so it is a negotiated term, not a default.

What about federal, military and state government plans?

Government plans sit outside ERISA’s QDRO system, and an order drafted for a private 401(k) can be rejected outright.

Source: 5 CFR § 838.302 (OPM). A former spouse awarded part of a FERS or CSRS annuity applies to OPM in writing with a court-certified copy of the order. Source: OPM, Court-Ordered Benefits FAQ. The Thrift Savings Plan has its own requirements: an order must expressly refer to the “Thrift Savings Plan” and be written in terms appropriate to a defined contribution plan, awarding a dollar amount, a percentage of the account, or a survivor annuity. Source: 5 CFR § 1653.2 (Thrift Savings Plan).

Military retired pay is governed by the Uniformed Services Former Spouses’ Protection Act. Total payments under all court orders “may not exceed 50 percent of such disposable retired pay”, and direct payment by the government of a property award requires a marriage of 10 years or more overlapping at least 10 years of creditable service. Source: 10 U.S.C. § 1408 (Cornell LII). State and local government plans and 457(b) plans follow 26 U.S.C. § 414(p)(11) and their own plan rules. Source: 26 U.S.C. § 414 (Cornell LII).

Social Security is not divided at all. A divorced spouse may be entitled to benefits on the worker’s record if the marriage lasted at least 10 years, the claimant is unmarried and age 62 or older, and other conditions are met. Source: 20 CFR § 404.331 (Social Security).

How long after a divorce can you file a QDRO?

There is no federal deadline. The Department of Labor regulation is direct:

Source: 29 CFR § 2530.206 (Cornell LII). The Department of Labor confirms an order issued “after the participant’s death, divorce, or annuity starting date” can still qualify. Source: U.S. Department of Labor QDRO guide. State law may impose its own limits, and the order still cannot require a benefit the plan does not offer at the time it is submitted.

No deadline does not make delay harmless. Until a qualified order is on file, the plan pays according to its own documents. In a case where a divorce decree said the former spouse waived the plan benefits but the beneficiary form was never changed, the Supreme Court held that the plan properly paid the former spouse, because “ERISA provides no exception to the plan administrator’s duty to act in accordance with plan documents.” Source: Kennedy v. Plan Administrator for DuPont, 555 U.S. 285 (2009). The same logic cuts the other way when a QDRO is never filed: the participant can retire, take a lump sum, borrow, roll the money out, remarry or die, and each event can make the award harder to collect, or in some cases no longer collectible from the plan. The usual practice is to draft and pre-clear the order with the plan before the decree is final.

Are equal retirement balances equal in value?

No. Each account type carries a different tax profile. Traditional IRA and 401(k) withdrawals are taxed as ordinary income, while qualified Roth distributions are tax-free. Source: IRS, Traditional and Roth IRAs. Taxable brokerage accounts are taxed on dividends and interest as they are paid and on gains when assets are sold, with long-term gains taxed at rates the IRS states are no higher than 15% for most individuals, with 0% and 20% brackets as well. Source: IRS Topic No. 409, Capital Gains and Losses.

Illustrative example, hypothetical figures: the table ignores state tax, the timing of withdrawals and future growth, all of which change the answer. Its point is narrower. A settlement that gives one spouse $300,000 of Roth money and the other $300,000 of traditional 401(k) money is not equal, and the gap in this example is $72,000. An after-tax comparison is the only way to know whether a proposed split is the split it claims to be. Your tax professional should confirm the rates that apply to you. For how this interacts with community and separate property, see the community property divorce guide.

How to divide a 401(k), IRA or pension in divorce, step by step

1. Inventory every plan and accountCollect recent statements, summary plan descriptions and each plan’s QDRO procedures. Include old employer plans, IRAs, pensions not yet in pay status, government plans and any plan loans.
2. Separate marital and non-marital portionsIdentify balances or service before the marriage and after the cut-off date your state uses. Pre-marriage balances require records to trace; pensions use a time-based fraction.
3. Compare after tax, not by balancePut traditional, Roth and taxable assets on the same after-tax footing before trading one for another, and model cash needs.
4. Decide the form of each awardDollar amount or percentage, valuation date, treatment of gains and losses, loans, shared payment or separate interest, and survivor coverage.
5. Draft the order to each plan’s rulesYour attorney or a QDRO specialist drafts, using the plan’s model language where it exists, and submits a draft for pre-approval.
6. Enter the order and send it to the planAfter the judge signs, send a certified copy to the plan administrator and confirm in writing that the order has been determined to be qualified.
7. Choose rollover or cash deliberatelyDecide how much, if any, to take in cash from the employer plan under the QDRO, and roll the rest directly, which avoids the 20% withholding that IRS Publication 575 describes.
8. Update beneficiaries and confirm completionChange beneficiary designations where your decree and the law allow, and keep confirmation that each account was actually divided.

Many couples reach these terms in divorce mediation; the drafting steps are the same. The cost of drafting QDROs and related experts is one of the line items covered in the guide to divorce costs.

Where a financial analysis fits alongside your attorney

Whether an order satisfies a particular plan is a legal and drafting question for your attorney and, where needed, a QDRO specialist. A divorce financial analysis answers a different question: what the proposed division is worth to each spouse after tax and over time, and which order of transfers preserves value. The divorce financial advisor page explains that analysis, and the services overview explains how it is delivered.
