Two accounts. Same balance. Completely different value. This is one of the most consequential misunderstandings in divorce financial planning, and it catches people off guard more often than you might expect – even sophisticated ones. If you are going through a divorce with a complex estate, knowing how to read the after-tax value of each asset on your balance sheet is not a minor detail. It shapes every major decision in the settlement.
A divorce financial planner spends a significant portion of their work correcting the instinct to treat dollar amounts as equivalent across different account types. They rarely are.
The Face Value Problem
When a marital estate gets laid out on a spreadsheet, the numbers look clean. A brokerage account showing $1,000,000. A traditional 401(k) at $1,000,000. A Roth IRA at $400,000. The natural impulse is to treat those figures as comparable – to divide them the way you would divide any other asset, by value.
The problem is that none of those accounts delivers $1,000,000 to the person who receives it. Each one carries a different tax profile, and the actual after-tax value depends on when and how the funds are accessed, what the tax rate will be at that time, and what embedded gains or deferred liabilities are sitting inside the account right now.
Treating pre-tax and after-tax assets as equivalent in a settlement is one of the most reliable ways to produce an agreement that looks balanced and is not.
What Is Actually Inside That Brokerage Account
A taxable brokerage account holding $1,000,000 sounds straightforward. But the relevant question is not what it is worth today – it is what it cost originally, and what has grown since then.
If you and your spouse accumulated those assets over 20 years and the original cost basis is $400,000, there is $600,000 in unrealized capital gains sitting inside that account. That gain does not trigger a tax liability until the assets are sold, but the liability exists. It is embedded in every position, and whoever receives that account in a settlement also receives the obligation to pay capital gains tax when those positions are eventually liquidated.
Depending on the assets held, the holding period, and the income level of the person receiving the account, that embedded tax cost could represent a meaningful reduction from the face value. Long-term capital gains rates in Massachusetts layer state tax on top of federal rates, which matters when you are working through the math on a substantial account.
The point is not that brokerage accounts are unfavorable assets. It is that their after-tax value depends on information that does not appear on the account statement.
Retirement Accounts Are Pre-Tax Obligations
A traditional 401(k) or IRA presents a different structure. Every dollar in a pre-tax retirement account has never been taxed. Contributions went in before income tax was applied, and the growth inside the account has been tax-deferred. When distributions come out in retirement, every dollar is taxed as ordinary income.
That means a $1,000,000 traditional 401(k) is not worth $1,000,000 in any practical sense. It is worth $1,000,000 minus the income tax that will be owed on distributions. How much that reduces the effective value depends on the recipient’s tax bracket in retirement, the state they live in at that time, and how large those distributions are relative to their other income. These are not knowable with certainty, but they are modelable, and ignoring them entirely produces a distorted picture.
The contrast with a Roth IRA is sharp. Roth contributions are made with after-tax dollars, and qualified distributions come out tax-free. A $400,000 Roth IRA and a $400,000 traditional IRA are not the same asset. The Roth balance is closer to face value for a person with a long time horizon. The traditional balance carries a deferred tax obligation that needs to be accounted for in any serious analysis.
Real Estate and Liquidity Carry Their Own Complexity
The marital home and investment real estate introduce a different set of considerations. Capital gains exclusions for primary residences exist under federal law, but they have limits, and those limits interact with the sale price, the ownership structure, and how long each party has lived in the property. For high-value Boston-area real estate, the gain above any applicable exclusion triggers taxable income that needs to be factored into the after-tax analysis.
Investment real estate often adds depreciation recapture to the picture. If a property has been depreciated over time, the accumulated depreciation reduces the cost basis and creates a taxable gain on sale that goes beyond what the simple appreciation would suggest. This is a detail that matters a great deal in the math and is easy to miss if the analysis is being done at a surface level.
Why This Requires More Than a Spreadsheet
Running a side-by-side comparison of assets at face value takes an hour. Running a thorough after-tax analysis of a complex marital estate takes considerably longer, and it requires understanding the tax treatment of each asset type, the cost basis documentation for each position, the expected holding period and distribution timing, and the individual tax situation of each spouse going forward.
This is the core of what a high net worth divorce financial planner does in the context of a settlement negotiation. The goal is not to favor one party over the other. It is to make sure that when an agreement is signed, both parties understand what they are actually receiving – not just what the account statement says.
Projections can model different division scenarios using stated assumptions about tax rates and time horizons. Those projections do not predict the future, but they surface tradeoffs that are invisible when you work from face value alone. A settlement that appears equal at the time of signing can look very different five or ten years later depending on how the after-tax consequences play out.
Getting the Analysis Right Before You Sign
If your estate includes taxable brokerage accounts, retirement accounts of different types, real estate, stock-based compensation, or business interests, you need someone who can read the full tax picture before you finalize anything. This is not about complicating the process. It is about making informed decisions with accurate information.
The couples I work with in the Boston area are often financially sophisticated. Many of them still arrive at the table with a face-value view of their assets because nobody has walked them through the embedded tax analysis specific to their situation. Once that analysis is on the table, the conversation about what a fair division actually looks like changes.
If you are working through a collaborative divorce and want to understand the after-tax value of what is being divided, I would be glad to walk through your specific situation.
