401(k) vs. Brokerage Account in Divorce: Which Should You Keep?
In divorce settlements, couples often negotiate which spouse keeps which assets. A common trade-off: one spouse keeps the 401(k) while the other keeps a brokerage account of similar value. On paper, $200,000 in a 401(k) and $200,000 in a brokerage account look equal. In reality, they are not — because the tax treatment, access rules, and long-term value of these accounts are fundamentally different.
- A 401(k) holds pre-tax dollars — every dollar withdrawn will be taxed as ordinary income. A $200,000 401(k) is worth less than $200,000 after taxes.
- A brokerage account holds after-tax dollars. Gains are taxed at the lower long-term capital gains rate (0%, 15%, or 20% for most people), and the original contributions (cost basis) are not taxed at all when withdrawn.
- 401(k) withdrawals before age 59½ generally incur a 10% early withdrawal penalty, though a QDRO-related distribution is an exception.
- Brokerage account funds can be accessed at any age without penalty.
- To compare fairly, calculate the after-tax value of each account, not the face value.
The tax problem with 401(k)s
A traditional 401(k) is funded with pre-tax dollars, meaning the money went in before income taxes were deducted. The trade-off is that every dollar withdrawn in retirement — both contributions and growth — is taxed as ordinary income at your marginal tax rate.
If you are in the 22% federal bracket and your state income tax is 5%, a $200,000 401(k) withdrawal would generate roughly $54,000 in taxes, leaving you with approximately $146,000. The exact amount depends on your total income, filing status, and state. The point is that the face value of a 401(k) significantly overstates its after-tax value.
This matters enormously in divorce negotiations. If one spouse takes a $200,000 401(k) and the other takes a $200,000 brokerage account, the spouse with the brokerage account is getting more real, spendable value — potentially tens of thousands of dollars more.
Why brokerage accounts are more flexible
A taxable brokerage account is funded with after-tax dollars. When you sell investments in a brokerage account, you only owe taxes on the gains — not the original investment. And if those gains are long-term (held for more than one year), they are taxed at the preferential long-term capital gains rate, which is 0% for individuals earning up to approximately $48,350 (2026), 15% for most taxpayers, and 20% for high earners.
Additionally, the cost basis — the amount you originally invested — comes out tax-free. If your $200,000 brokerage account has a cost basis of $140,000 and $60,000 in gains, only the $60,000 in gains is subject to tax upon sale. At a 15% long-term capital gains rate, that is $9,000 in taxes — compared to roughly $54,000 on the 401(k). The difference is stark.
Brokerage accounts also have no age restrictions. You can withdraw funds at any time without penalty, giving you immediate access to the money if you need it for housing, living expenses, or an emergency. A 401(k) generally penalizes withdrawals before age 59½ with a 10% early withdrawal penalty on top of income taxes (though QDRO distributions in divorce are exempt from the early withdrawal penalty).
How to compare them fairly
The correct way to compare these accounts in a divorce settlement is to calculate the after-tax value of each. A financial advisor or CDFA (Certified Divorce Financial Analyst) can help with this calculation, which considers your expected tax bracket in retirement, the cost basis of the brokerage account, and your time horizon.
As a rough rule of thumb: a 401(k) is typically worth 20–35% less than its face value after accounting for future taxes, while a brokerage account’s after-tax value depends on the ratio of gains to cost basis and could be 90–95% of face value for accounts with a high cost basis.
When the 401(k) is still the better choice
Despite the tax disadvantage, there are situations where keeping the 401(k) makes sense. If you are close to retirement and plan to draw from it within a few years, the growth potential and tax-deferred compounding may outweigh the flexibility of the brokerage account. If you expect to be in a lower tax bracket in retirement than you are now, the effective tax rate on withdrawals may be lower than the current calculations suggest.
Also, 401(k) accounts have stronger creditor protection in most states — meaning they are harder for creditors to reach in the event of a lawsuit or bankruptcy. For someone in a profession with higher liability risk, this protection has real value.
The bottom line
Do not accept a dollar-for-dollar trade between a 401(k) and a brokerage account without understanding the tax implications. A $200,000 401(k) and a $200,000 brokerage account are not equal. Have your settlement terms evaluated on an after-tax basis to ensure you are getting a fair deal.
