Capital Gains Tax When Selling Your Los Angeles Home: What to Know Before You List

How much capital gains tax do you pay when selling a home in Los Angeles?

California taxes home sale profits as ordinary income, not at a separate capital gains rate, which means state tax alone can reach 13.3% for high earners. Combined with federal long-term rates of 15% or 20% (plus a potential 3.8% Net Investment Income Tax), total liability can exceed 33% of your taxable gain. Most sellers who have owned and lived in their home for at least two of the last five years can exclude up to $250,000 in gains from tax ($500,000 for married couples filing jointly) before any of that applies.

You've built real equity in your Los Angeles home. Maybe you bought in Hollywood Hills fifteen years ago and the market has been good to you. Maybe you've owned a place in Sherman Oaks or Brentwood since the early 2000s and the appreciation has been significant. Whatever your situation, before you call an agent and start thinking about list price, the tax question deserves a clear answer.

Capital gains tax on a home sale is one of the topics I walk clients through regularly. The confusion is understandable. California handles it differently than most people expect, and the numbers on a luxury LA sale can be large enough to change the timing and structure of your decision.

Here's what you need to know.

California's Tax Treatment Is Different From What Most Sellers Expect

Most states tax long-term capital gains at a separate, reduced rate. California does not. The state treats home sale profits as ordinary income, taxed on the same progressive schedule as wages and salary. At the top of that scale, the California rate hits 13.3%.

That's the highest state capital gains rate in the country.

On a $3 million taxable gain, the California portion alone comes to roughly $399,000. That's before a dollar of federal tax.

On the federal side, long-term capital gains rates are 0%, 15%, or 20%, depending on your total income. Most LA luxury sellers fall into the 20% bracket. If your modified adjusted gross income exceeds $250,000 (single) or $500,000 (married filing jointly), you'll also owe a 3.8% Net Investment Income Tax on top.

Put it together: 20% federal, 3.8% NIIT, and 13.3% California state, and your combined marginal rate on taxable home sale gains is 37.1%. On a $3 million gain, that's over $1.1 million in combined federal and state taxes.

I'm not telling you this to discourage you from selling. I'm telling you because these numbers are large enough that the timing, structure, and exclusion eligibility of your sale are worth thinking through before you list.

The Primary Residence Exclusion: $250,000 or $500,000 Off the Top

The best news in this conversation is Section 121, the primary residence exclusion. If your home has been your primary residence, you can exclude a meaningful amount of gain from tax entirely.

The amounts are:

• $250,000 for single filers
• $500,000 for married couples filing jointly

To qualify, you must meet two tests. First, you must have owned the home for at least two years out of the last five. Second, you must have used it as your primary residence for at least two of those same five years. The two years don't need to be consecutive, and the ownership and use periods don't need to overlap completely, though they usually do.

One limit worth noting: you can only claim this exclusion once every two years. If you sold another home and used the exclusion in 2024, you'll need to wait until 2026 or later to claim it again.

California mirrors the federal exclusion at the state level, so the same $250,000 or $500,000 amount is excluded from California income tax as well.

Your cost basis matters more than you might think.

The exclusion applies to your gain, not your sale price. Your gain is the difference between what you sell for and your adjusted cost basis.

Your adjusted basis starts with what you originally paid for the property. From there, you add the cost of capital improvements you've made over the years: a room addition, kitchen or bathroom remodel, new roof, pool installation, HVAC replacement, or landscaping that qualifies. You can also factor in certain selling costs from previous sales of the same property.

What doesn't count: routine maintenance and repairs. Painting the house, fixing a leak, or replacing a worn-out appliance won't adjust your basis.

If you've owned your home for ten, fifteen, or twenty years and done real work on it, tracking down those records now is worth the effort. Each dollar of documented improvement increases your basis and reduces your taxable gain.

What the Numbers Look Like on an LA Luxury Sale

Let's run through a realistic example to show how these pieces fit together.

Say you bought a home in the Hollywood Hills for $900,000 in 2010. You've lived there as your primary residence the entire time. You renovated the kitchen and bathrooms in 2019 at a cost of $180,000. You're now selling for $4.2 million.

Your adjusted cost basis: $900,000 (purchase) + $180,000 (improvements) = $1,080,000.

Your gross gain: $4,200,000 minus $1,080,000 = $3,120,000.

You're married filing jointly, so you exclude $500,000 under Section 121.

Taxable gain: $3,120,000 minus $500,000 = $2,620,000.

At a combined federal and California rate of approximately 37%, the tax on that $2.62 million comes to around $969,400.

That's in addition to the commissions, escrow fees, and transfer taxes that come out at closing. If you want to see how those transaction costs break down at different price points, What LA Sellers Pay at Closing: Your 2026 Net Sheet walks through the full picture.

And if your sale price exceeds approximately $5.15 million, you'll also owe the Measure ULA transfer tax on top of capital gains. The ULA tax is a separate transaction cost paid at closing, not an income tax, but it stacks on top of the capital gains liability in a way that materially changes your net. For a full breakdown, see Measure ULA in Los Angeles: What Every Seller Above $5 Million Needs to Know. On a $7 million sale, for example, you could be looking at Measure ULA of $280,000 and capital gains taxes well into the six-figure range, all coming out before you receive a dollar.

Sell in a lower-income year. Because California taxes your gain as ordinary income, your overall income level in the year you sell affects your effective rate. If you're planning to retire, change jobs, or have a year with meaningfully lower income for other reasons, the timing of your sale can reduce your California tax burden.

Document capital improvements before you list. Pull together receipts, contracts, and permits for any significant work you've done on the property. A higher basis reduces your taxable gain directly.

Partial exclusion eligibility. If you haven't fully met the two-year ownership or use requirements, you may still qualify for a prorated exclusion in certain circumstances, including a job relocation, a health-related move, or other unforeseen events. A tax advisor can tell you whether partial relief applies to your situation.

Investment properties and 1031 exchanges. If the property is not your primary residence, Section 121 doesn't apply. If you've owned it as a rental or investment, a 1031 exchange can defer the capital gains tax by rolling the proceeds into another qualifying investment property. That's a separate conversation with its own rules and deadlines, but it's worth knowing the option exists.

Non-U.S. sellers. If you're not a U.S. citizen or resident, FIRPTA requires the buyer to withhold 15% of the total sale price at closing on sales above $1 million and remit it to the IRS. California has a parallel requirement under Form 593. These are separate from the capital gains calculation but affect your cash flow at close significantly.

The difference between walking into a sale without preparation and walking in with clear numbers can be hundreds of thousands of dollars. The specific amount you'll owe depends on your basis, filing status, income level, the year you sell, and whether you qualify fully for the Section 121 exclusion.

Frequently Asked Questions

Does California have a special lower tax rate for capital gains on a home sale?

No. California taxes home sale profits as ordinary income at the same progressive rates as wages, with a top rate of 13.3%. There's no separate, reduced capital gains rate in California. That's different from the federal system and from most other states, both of which do have lower long-term capital gains rates.

Can I avoid capital gains tax entirely on my Los Angeles home sale?

If you qualify for the primary residence exclusion, you can exclude up to $250,000 in gains from tax if you're single, or $500,000 if you're married filing jointly. Gains above those amounts are still taxable. If your property is an investment rather than a primary residence, a 1031 exchange can defer (not eliminate) the tax by rolling proceeds into another qualifying property.

What counts as a capital improvement for calculating my cost basis?

Capital improvements are permanent additions or upgrades that add value to the property, extend its useful life, or adapt it to a new use. Common examples include room additions, kitchen and bathroom remodels, new roofs, pools, HVAC systems, and solar installations that you own outright. Routine maintenance and repairs, including painting, fixing plumbing leaks, and replacing appliances, don't qualify.

Does Measure ULA count toward my capital gains calculation?

No. Measure ULA is a transfer tax paid at closing on sales above approximately $5.15 million in the City of Los Angeles. It's a transaction cost, similar to a commission or escrow fee, and it doesn't reduce your capital gain for income tax purposes. It does reduce your net proceeds from the sale, which is why it's worth looking at your total cost to sell before you set your list price expectations.

When do I actually pay the capital gains tax from my home sale?

Capital gains are reported on your federal and California state income tax returns for the year the sale closes. The tax is due when you file, typically by April 15 of the following year. If the expected liability is large enough, you may need to make estimated tax payments during the year of sale to avoid underpayment penalties. A CPA or tax advisor can help you figure out the right amount and timing.
