Worked example

A 2026 example, worked out

A California couple divorcing in 2026 owns a home worth $1,600,000 that they bought for $500,000 and improved by $100,000. Selling costs are $90,000. One earns $120,000, the other $60,000, and they own it 50/50.

Line	Amount
Your tax on the home sale	$56,275
Total gain on the house	$910,000
Carryover basis (what you paid plus improvements; IRC 1041)	$600,000
Sell before the divorce is final, joint return: your share of the tax	$56,275
Same, tax for the two of you	$112,550
Sell after the divorce, split 50/50: your tax	$54,565
Same, your ex's tax	$51,148
You keep the house and sell it later alone: your tax	$214,597

How it works

The rules behind the numbers

No tax when the house moves between you. A transfer to your spouse, or to a former spouse incident to the divorce (within 1 year, or under the divorce instrument within 6 years), is not a sale. The receiving spouse takes the old basis (IRC 1041; Temp. Treas. Reg. 1.1041-1T). The built-in gain moves with the house.
December 31 decides your filing status. If the divorce is final by December 31, you file as single (or head of household) for the whole year; if not, you can still file jointly (IRC 7703).
Joint return: one $500,000 exclusion. Married filing jointly, you exclude up to $500,000 if either owned the home and both lived in it 2 of the last 5 years (IRC 121(b)(2)). On separate returns, each excludes up to $250,000 of their own gain.
After the divorce: $250,000 each. Sold after the divorce, each of you reports your share and excludes up to $250,000. If only one of you still lives there, the one who moved out keeps the use test when the ex lives there under the divorce decree (IRC 121(d)(3)(B)).
Keeping the house means keeping the gain. The spouse who keeps the home takes the whole built-in gain at the old basis and later sells with one $250,000 exclusion. That is often the most expensive plan; weigh it when dividing other assets.
Count the time on ownership too. If the house came to you from your spouse, the time they owned it counts as yours (IRC 121(d)(3)(A)).

Common questions

Straight answers

Is it better to sell the house before or after the divorce?

Often before the divorce is final, in a year you can still file jointly, because the $500,000 exclusion covers the whole gain on one return. After the divorce, two $250,000 exclusions on your two shares can do as well when the gain is split evenly. Keeping it and selling alone later usually costs the most.

Do I owe tax when the house is transferred to my ex in the divorce?

No. A transfer incident to divorce is tax free under IRC 1041. Your ex takes your old basis, so the tax waits until they sell.

I moved out. Can I still use the home sale exclusion?

Yes, if your former spouse keeps living there under the divorce or separation instrument: their use counts as yours (IRC 121(d)(3)(B)). You still need 2 years of ownership in the 5 before the sale.

How is the gain split between us?

By ownership. Each of you reports the gain on your share and claims your own exclusion. On a joint return the gain and the exclusion are combined.

Does the state follow the same rules?

Most states follow the federal exclusion and IRC 1041. The calculator applies your state's 2026 rates to the taxable part.
