Dividing an IRA in a Montana Divorce

IRAs Follow Different Rules Than 401(k)s in Divorce

If you've been reading about dividing retirement accounts in a Montana divorce, most of the guidance focuses on 401(k) plans and the QDRO process. But IRAs — both traditional and Roth — don't use QDROs at all. They follow a simpler but easily mishandled process called a "transfer incident to divorce," and getting the mechanics wrong can trigger unnecessary taxes and penalties.

Montana's all-property system under MCA § 40-4-202 treats IRAs the same as any other marital asset. The court can divide IRA balances accumulated during the marriage, and even premarital IRA contributions can be allocated to the other spouse if the equitable distribution factors support it. The question isn't whether IRAs are divisible — it's how to execute the division correctly.

The Transfer Incident to Divorce: How It Works

Under IRC § 408(d)(6), an IRA interest can be transferred from one spouse to the other tax-free when the transfer is made under a divorce decree or written instrument incident to the decree. Common ways to carry out that transfer include:

1. Changing the name on the IRA — if all the assets are being transferred, the custodian changes the account name to the spouse or former spouse.
2. A direct trustee-to-trustee transfer — the court order or settlement instrument specifies the amount or percentage, and the IRA custodian moves the funds directly to the spouse's or former spouse's IRA (or a newly opened IRA). No check is issued to either spouse.

When done correctly, there's no taxable event. No income tax. No early withdrawal penalty. The receiving spouse takes ownership of their portion and can manage it as their own IRA going forward.

The Biggest Mistake: Taking a Distribution Instead of Transferring

Here's where people lose money. If the IRA owner withdraws funds from their account and then writes a personal check to their ex-spouse for "their share," the IRS treats the withdrawal as a taxable distribution to the IRA owner. That means:

• Income tax on the taxable portion of a traditional-IRA withdrawal; Roth IRA treatment depends on the account's contribution basis and whether the distribution is qualified
• A 10% additional tax if the IRA owner is under age 59½, unless an exception applies
• A difficult reporting problem to correct after the fact

The transfer must go directly from one IRA to another. The money should never touch either spouse's personal bank account during the transfer process.

Note that this is different from 401(k) plans, where a QDRO allows the receiving spouse to take a cash distribution directly from the plan without the 10% early withdrawal penalty (though income tax still applies). IRAs don't offer this early-withdrawal penalty exception because IRAs don't use QDROs.

Traditional IRA vs. Roth IRA: Tax Implications

The type of IRA affects the after-tax value of the transfer, even though the transfer itself is tax-free.

Traditional IRA. Pretax amounts in a traditional IRA are generally taxed as ordinary income when withdrawn; any after-tax basis is not taxed again. A $50,000 traditional IRA's after-tax value depends on the recipient's tax bracket, timing, and basis.

Roth IRA. Contributions to a Roth IRA were made with after-tax dollars, so qualified withdrawals in retirement are completely tax-free. A $50,000 Roth IRA is worth the full $50,000 in spending power. If your property worksheet lists a $50,000 traditional IRA and a $50,000 Roth IRA at the same value, the spouse getting the Roth is getting a better deal.

When dividing IRAs, adjust the values on your property worksheet to reflect this difference. Use a case-specific tax-adjustment factor based on the expected tax treatment, withdrawal timing, and any basis rather than applying a universal percentage. This produces a more equitable division even if the raw dollar amounts aren't perfectly equal.

How to Execute the IRA Transfer

1. Include the IRA division in your decree or settlement agreement. Specify the exact account, the custodian (Fidelity, Vanguard, Schwab, etc.), and the amount or percentage to be transferred.

2. The receiving spouse opens an IRA of the same type. A traditional IRA must be transferred to a traditional IRA. A Roth must go to a Roth. If the receiving spouse doesn't already have an account with the same custodian, they'll need to open one — many custodians can process the transfer between their own accounts faster than cross-custodian transfers.

3. Submit the decree to the IRA custodian. Most custodians have a specific form for divorce-related transfers. You'll typically need a certified copy of the final decree, the account number of the transferring IRA, and the account information for the receiving IRA.

4. Process as a trustee-to-trustee transfer. The custodian moves the funds directly. Neither spouse receives a check. No 1099-R should be issued for a properly executed transfer incident to divorce.

5. Confirm the transfer. Check both accounts within 30 days to verify the correct amount was moved. Errors are easier to correct immediately than months later.

Special Situations

Multiple IRAs. If one spouse has several IRA accounts, you don't need to split each one. You can transfer a total dollar amount from one account and leave the others untouched, as long as the decree specifies the arrangement.

Inherited IRAs. An inherited IRA (one received from a parent or other non-spouse) follows different rules and may not be divisible in the same way. These accounts have their own required minimum distribution schedules that would change if transferred. Consult the custodian before including an inherited IRA in your property division.

IRA contributions during separation. If the couple separated but didn't formally divorce for several years, contributions made during the separation period can be contested. Montana courts have discretion to determine whether post-separation contributions are marital or separate property based on the specific circumstances.
