Is your divorce split equal after tax?
A split that is 50/50 on paper is rarely 50/50 after tax. Each asset carries a different future tax bill for the spouse who receives it: investments keep their original cost, a 401(k) is taxed when drawn, the home may owe tax above the $250,000 exclusion. List what each of you keeps: we value every asset after tax under the 2026 rules and show the cash payment that evens it out.

Why paper values mislead
Assets move between spouses tax-free in a divorce, but the tax does not disappear: it moves with the asset. Whoever takes the low-basis stock takes its capital gains tax; whoever takes the 401(k) takes the income tax on it; whoever keeps the house takes the selling costs and any gain above the $250,000 exclusion. Cash and a qualified Roth carry none. Comparing values after tax, and settling the difference with a cash payment, is how financial analysts check a settlement.
Frequently asked questions
Is a 50/50 divorce split really 50/50?
Often not after tax. Assets that look equal on paper carry different future tax bills: $200,000 in a brokerage account bought for $50,000 comes with a $150,000 gain the receiving spouse will pay tax on, while $200,000 in cash carries none. In our example the split is 46.7% / 53.3% on paper and 47.2% / 52.8% after tax.
Is transferring assets in a divorce taxable?
Not at the time. Under 26 U.S.C. §1041 a transfer between spouses incident to divorce (within a year of the divorce, or related to it) is tax-free, and the spouse who receives it keeps the original cost basis. That is why the tax shows up later, when the asset is sold. A cash equalising payment is tax-free too.
Do I pay the 10% penalty if I cash out a 401(k) in a divorce?
Not on money paid to you from a 401(k), 403(b) or pension under a qualified domestic relations order (QDRO): 26 U.S.C. §72(t)(2)(C) removes the 10% early withdrawal tax. It is still taxed as income. An IRA split in a divorce is different: the transfer is tax-free, but cashing it out before 59½ does pay the 10% (IRS Topic 558).
How is the house taxed if one of us keeps it?
When it is sold, up to $250,000 of gain is tax-free for a single owner who owned it and lived in it for 2 of the last 5 years (26 U.S.C. §121). The ex-spouse’s years of ownership count, and so do years the ex lived there under the divorce decree. Gain above that is taxed as a long-term capital gain. The calculator values the home as if sold, with selling costs.
Does this calculator divide property or set support?
No. It does not decide what is marital or separate property, what a court would award, child support or alimony. It shows the after-tax value of a split you are considering, under 2026 federal tax rules and your state rate. Check the result with your lawyer, mediator or a divorce financial analyst (CDFA).
