How to Split an IRA in Divorce Without a Tax Bill

IRAs don't need a QDRO. But the mechanics of the transfer matter — the wrong move converts a tax-free split into a taxable distribution with a penalty attached.

The governing rule: IRC § 408(d)(6)

Under IRC § 408(d)(6), the transfer of an individual's interest in an IRA to a spouse or former spouse is not treated as a taxable distribution — provided two conditions are met:¹

1. The transfer is made pursuant to a divorce or separation instrument — a divorce decree, a decree of separate maintenance, or a written separation agreement incident to such a decree.
2. The transfer is executed as a direct transfer — either a trustee-to-trustee transfer to the receiving spouse's IRA, or a retitling of the account into the receiving spouse's name.

When both conditions are met, the receiving spouse takes over the IRA as their own account. There is no income tax, no 10% penalty, and no reporting of a distribution.

The two valid transfer methods

The IRS specifies two mechanics that qualify under § 408(d)(6):¹

• Retitling (name change): If the entire IRA is being transferred, the account owner simply requests the custodian to change the name on the account from the transferring spouse to the receiving spouse. The same account, same custodian, same investments — just a new owner.
• Trustee-to-trustee transfer: If a partial transfer is involved, or the receiving spouse wants the account at a different institution, the custodian transfers the specified amount directly from the transferring spouse's IRA to an IRA established in the receiving spouse's name. The receiving spouse never touches the funds.

What the divorce instrument must say

The transfer doesn't have to be ordered by the court — it just has to be made pursuant to a qualifying instrument. In practice, the divorce decree or written separation agreement should specifically identify:

• The IRA accounts being split (name, institution, approximate value or percentage)
• The amount or percentage going to each party
• A direction that the transfer is to be made incident to the divorce

Most custodians (Fidelity, Vanguard, Schwab, etc.) have a standard transfer form for divorce-related IRA splits. You'll typically need to provide a copy of the relevant pages of the divorce decree or separation agreement alongside that form.

Roth IRA: the extra complications

Roth IRAs are transferred under the same § 408(d)(6) rule — directly, incident to divorce — but two nuances matter:

Contribution basis tracking (Form 8606)

Roth IRA contributions are made with after-tax dollars, and the basis (total after-tax contributions) is tracked on Form 8606. When a Roth IRA is split, the basis should be allocated proportionally between the two accounts. If the IRA owner has filed Form 8606 each year, this is straightforward math — but if they haven't, the receiving spouse may later face difficulty proving their Roth distributions are tax-free.

Both parties should request copies of all prior Form 8606 filings and, if the Roth account contains years of accumulated basis, confirm the allocated amount in the divorce agreement language.

The 5-year holding clock

For a Roth IRA distribution to be "qualified" (fully tax- and penalty-free), two conditions must be met: the owner must be 59½ or older, and the Roth IRA must have been in existence for at least 5 years. The 5-year clock runs from January 1 of the tax year of the first Roth IRA contribution, regardless of which account the money is in now.

When a Roth IRA is transferred incident to divorce, the receiving spouse's 5-year clock is generally tied to their own oldest Roth IRA — which may already be running. If the receiving spouse has never had a Roth IRA before, the clock starts in the year of the transfer. This can affect when the receiving spouse can take penalty-free distributions.

Note: IRS guidance on the interaction of Roth 5-year clocks and divorce transfers is limited. A tax advisor familiar with the specific accounts and contribution history should confirm the analysis before the receiving spouse takes any distribution.

SIMPLE IRA: the 2-year trap

SIMPLE IRAs have a rule that trips up divorce settlements involving employees at small businesses: if you take an early distribution from a SIMPLE IRA within 2 years of first participating in the plan, the additional early withdrawal penalty is 25% — not the standard 10%.³

The 2-year period starts when the employer makes the first contribution to the participant's SIMPLE IRA. The rule continues to apply even if the participant has since left the employer.

The § 408(d)(6) incident-to-divorce transfer avoids this entirely — a direct transfer to the receiving spouse's IRA is not a distribution and triggers no penalty. But if the settlement agreement requires a cash payment funded by a SIMPLE IRA cash-out, and the participant is within the 2-year window, the 25% penalty applies to the amount withdrawn.

Additionally, within the 2-year period, SIMPLE IRA funds generally cannot be rolled into a traditional IRA or other non-SIMPLE plan.³ This affects post-divorce consolidation planning for the receiving spouse.

SEP-IRA: same rules as traditional IRA

A SEP-IRA (Simplified Employee Pension) is treated exactly like a traditional IRA for divorce purposes. It requires no QDRO, uses the § 408(d)(6) direct transfer mechanism, and is taxable as ordinary income on withdrawal. The transfer is straightforward — the main complication is that SEP accounts can be large (employer contributions up to 25% of compensation, or $70,000 in 2026), so the after-tax value analysis matters more.⁴

Inherited IRA: not transferable

An inherited IRA — one you received as a beneficiary from a parent, sibling, or other deceased person — cannot be transferred to your spouse via § 408(d)(6). Inherited IRAs are tied to the original beneficiary's identity; the 10-year distribution rule and other RMD requirements run on that beneficiary's timeline. You cannot retitle an inherited IRA in someone else's name.⁵

If one spouse holds a large inherited IRA, it typically stays with that spouse in the settlement. Its after-tax value is affected by the 10-year drawdown requirement — a $500,000 inherited IRA that must be emptied in 10 years has a different effective value than a $500,000 traditional IRA the owner can keep growing until age 73. A CDFA can model this correctly; most attorneys don't.

Six mistakes that generate unnecessary tax bills

1. Taking a cash distribution to "pay" the spouse. As described above — this is a taxable distribution, not a § 408(d)(6) transfer. The IRA owner, not the receiving spouse, owes the tax.
2. Doing the transfer before the divorce instrument is signed. A § 408(d)(6) transfer must be made pursuant to a qualifying instrument. Transfer the IRA before the decree or written agreement is in place and you lose the exclusion.
3. Failing to allocate Roth basis in the agreement. If the Roth IRA has significant after-tax contribution basis, omitting the allocation language creates a Form 8606 gap that can cost the receiving spouse years later.
4. Treating a SIMPLE IRA like any other IRA within the 2-year window. Triggering a cash distribution within 2 years = 25% penalty instead of 10%. The direct transfer avoids this, but a settlement requiring a cash buyout from a SIMPLE IRA doesn't.
5. Valuing a pre-tax IRA at face value in the settlement. A $300,000 traditional IRA has approximately $195,000–$225,000 of after-tax value at a 25–35% marginal rate. Taking equal "dollar amounts" of pre-tax IRA and post-tax savings is not an equal trade.
6. Ignoring the inherited IRA. Inherited IRAs can't be transferred and have forced distribution timelines that reduce their effective value. Treating them as equivalent to a traditional IRA in the asset split overstates one spouse's position.

What a CDFA adds here that your divorce attorney doesn't

Your divorce attorney will ensure the agreement language qualifies as a "divorce or separation instrument" under § 408(d)(6). That's necessary but not sufficient.

A CDFA-credentialed fee-only financial advisor goes further:

• Calculates the after-tax value of every retirement account — Roth vs traditional, pre-tax vs after-tax — so the asset split is actually equal in after-tax terms.
• Models the inherited IRA's effective value given the 10-year distribution requirement vs other accounts.
• Identifies whether a SIMPLE IRA's 2-year window creates a cash-flow problem if the settlement requires a cash buyout.
• Flags Form 8606 basis issues before the transfer so the receiving spouse has documentation from day one.
• Compares the IRA allocation against other settlement options — pension, home equity, taxable brokerage — in after-tax present-value terms.

The average IRA balance in a divorce-age household is $200,000–$400,000. A tax mistake in the transfer or settlement valuation can cost $20,000–$80,000 in unnecessary taxes. A fee-only CDFA's engagement fee is almost never more than a small fraction of that.
