The $500,000 Home-Sale Exclusion Hasn't Changed Since 1997. Your California House Has.
You bought the house a long time ago. Somewhere between three and six hundred thousand dollars, depending on the year and the street. It is now the largest asset you own, the kids are gone, the stairs are getting less charming, and you have started running the numbers on selling.
Most people run those numbers with one figure in mind: the $500,000 exclusion. It is the right figure. It is also, for a long-held California home, the smaller part of the story.
What the Exclusion Covers, and What California Does With the Rest
This article is for California homeowners in or approaching retirement who bought decades ago and are weighing a sale in 2026. The short answer: Internal Revenue Code Section 121 lets a married couple filing jointly exclude up to $500,000 of gain on a primary residence, and $250,000 if single, provided you owned and lived in the home for at least two of the five years before the sale. California conforms to that exclusion. California then taxes every dollar of gain above it as ordinary income.
Two details do most of the damage.
The first is that the exclusion has never been indexed. Congress set $250,000 and $500,000 in the Taxpayer Relief Act of 1997 and has not moved them since. Proposals to index the amounts have surfaced repeatedly and none has passed. California real estate has not been standing still for those twenty-nine years.
The second is that California has no preferential rate for long-term gains. The Franchise Tax Board's own guidance states that California does not have a lower rate for capital gains and that all capital gains are taxed as ordinary income. There is no separate schedule. A gain you have held for thirty years is treated on your Form 540 exactly like a paycheck, running up the same bracket ladder to a top rate of 13.3% — 12.3% plus the 1% Mental Health Services Tax that applies to taxable income over $1 million under Proposition 63.
What the Two Paths Actually Look Like
Take an illustrative case. A married couple bought in 1990 for roughly $400,000 and the home is worth roughly $3.2 million today. Assume no rental history and no major capital improvements to add to basis — both assumptions matter, and both are discussed below. The gain is about $2.8 million. The exclusion removes $500,000. About $2.3 million is taxable.
At the top marginal rates, that gain faces 20% federal long-term capital gains tax, the 3.8% net investment income tax on the non-excluded portion, and California ordinary income tax approaching 13.3%. Combined, the top of that stack lands near 37%. On $2.3 million, the tax is in the neighborhood of $850,000 — though the actual figure depends heavily on the rest of the year's income, because California stacks the gain on top of everything else you report and walks it up the brackets from there. A couple with significant IRA withdrawals or a business sale in the same year pays more on the same house than a couple with modest income does.
Now the other path. If you hold the property and it passes at death, Section 1014 resets the basis to fair market value. The entire lifetime gain disappears for income tax purposes. The One Big Beautiful Bill Act left Section 1014 in place — there is no sunset or repeal scheduled to plan around.
That is the fork. Sell during your lifetime and the gain above the exclusion is taxed at some of the highest combined rates in the country. Hold, and it may never be taxed at all. Neither answer is automatically correct, because the right one depends on whether you need the money, whether you want to stay, and what else is happening on your return.
Why the Deed Decides Half of This
Here is the part almost nobody checks before listing.
California is a community property state, and under Section 1014(b)(6) community property receives a step-up on both halves when the first spouse dies — the deceased spouse's half and the surviving spouse's half. Most states step up only the decedent's half.
Whether you get that treatment depends on how title is held. Property held as community property, or as community property with right of survivorship, or as community property inside a properly drafted revocable trust, generally qualifies. Property held in joint tenancy generally does not: only the decedent's one-half interest steps up, and the survivor's half keeps its original basis.
On a home purchased for $400,000 and worth $3.2 million, that distinction is worth well over a million dollars of basis to the surviving spouse. It is determined by wording on a deed that was often chosen at a title company decades ago, by people who were focused on closing.
The Two-Year Window Most Surviving Spouses Never Hear About
There is a timing rule worth knowing before it applies rather than after. Under Section 121(b)(4), a surviving spouse may generally claim the full $500,000 exclusion rather than the $250,000 single amount if the sale occurs within two years of the spouse's death and the joint filing requirements were met beforehand.
Combined with a community property double step-up, a sale in that window can produce a very different result than the same sale three years later. This is not a reason to rush a grieving decision. It is a reason to know the clock exists.
Where This Decision Actually Gets Made
Three things change the answer and none of them live inside the house.
Basis is usually larger than people think. Capital improvements over thirty years — a new roof, an addition, a kitchen — add to basis if you can document them. Most people cannot, because they did not know they would need to. Receipts and permits are worth finding before a sale, not after.
Prior rental use changes the math. If the home was ever a rental, depreciation you took, or were entitled to take, is recaptured as unrecaptured Section 1250 gain at a maximum federal rate of 25%, and periods of non-qualified use can reduce the exclusion itself.
Timing interacts with everything else on the return. Because California stacks the gain on ordinary income, the year you sell determines the state bracket the gain climbs into. That interacts with Roth conversion plans, the timing of IRA withdrawals, and Medicare premium calculations two years out.
This is the kind of decision where the tax answer, the estate answer, and the income answer are the same answer. The deed determines the basis. The basis determines the tax. The tax determines how much of the proceeds actually fund the next chapter, and what is left to pass on. A CPA looking only at this year's return, an attorney looking only at the documents, and an advisor looking only at the portfolio will each see one face of it.
That coordination is what the CRAve Life Advisory Process℠ is built to provide: the sale is evaluated against the tax year it lands in, the estate documents that govern the basis, and the income plan the proceeds are meant to support — before the house is listed, when the answer can still change.
Before You List
If you are within a few years of selling, four questions are worth answering now, while every one of them still has options attached:
How is title currently held, and does it qualify for the community property double step-up? What is your documented basis, including improvements? Was the property ever a rental? And what else will be on your tax return in the year you plan to sell?
If you already work with an advisor and have never been walked through these four, that is worth raising with them. If you would like a second read, we are glad to be that.
