The House or the IRA? After-Tax Value in a Divorce
§§ 121, 1041, 72(t) · reviewed September 7, 2026
Compares what the house and the retirement account are each worth after tax, when a divorce trades one against the other. AboutLess
In plain words. A common settlement gives one spouse the house and the other the retirement account, at matching numbers. But the house carries a mortgage, the cost of selling it one day, and tax on its profit above what a single person can exclude; the retirement account carries income tax on every dollar taken out, and a penalty before 59½. This tool takes both assets and your tax rates and shows what each is worth after those costs, and how large the retirement account would have to be to truly match the house.
Why it matters. This is the biggest trade in most divorces, and it is usually made on the statement numbers. The after-tax numbers can differ by a hundred thousand dollars or more.
An example. A house worth $800,000 with a $200,000 mortgage, bought for $300,000, against a $600,000 IRA. After selling costs and the tax on the gain, the house is worth about $522,000; after 24 percent income tax, the IRA is worth $456,000. To match the house, the IRA would need to be about $686,000.
Where it stops. It uses today's values and your rates. It cannot know what the house will be worth later or what rate the IRA will be taxed at when withdrawn, and it does not include the cost of carrying the house on one income. The pension version of this question needs an actuary. Everything it leaves out.
Today's market value, before the mortgage is taken off.
The account's current balance, before any tax.
The purchase price plus what was spent on improvements. The gain is measured from this.
The federal bracket that will apply when the money comes out.
The federal rate on the gain when the house is eventually sold.
Agent commission and closing costs, as a share of the sale price.
- Taxable gain on the house
- $202,000
- $452,000 of gain, less the $250,000 exclusion
- Tax owed on the IRA when withdrawn
- $144,000
- 24% of every dollar withdrawn
- IRA balance that equals the house after tax
- $686,447
- The even trade, once both sides are taxed
Whoever keeps the house will one day sell it as a single filer with a $250,000 exclusion, and can count the years the other spouse lived there. Whoever takes the IRA pays income tax on every dollar withdrawn, at whatever rate applies then, plus a penalty before 59½ unless the money comes straight out of an employer plan under the court order. Neither number appears on the settlement sheet.
This follows the federal rules for the home sale exclusion after a divorce, for tax-free transfers between divorcing spouses, and for the early-withdrawal penalty exception on an employer plan split by court order. It uses today's values and the rates you set, with no growth in either asset, no investment surtax, no state tax, and no cost of carrying the house on one income (the sell-or-keep tool prices that). Educational, not advice.
This is a simplified model, not your actual tax return or plan. It only knows what you type in, leaves out rules that may apply to you, and cannot weigh the other facts and trade-offs a real decision depends on. Before you act, talk with a professional who knows your whole situation.
