Property taxes in Los Angeles start at 1% of assessed value, and in most of Los Angeles County the total rate does not exceed 1.25% once voter-approved debt is added (Los Angeles County Auditor-Controller). The number that catches people is not the rate, it is the base. Proposition 13 freezes your assessed value until the property changes hands, so the seller's tax bill tells you nothing about yours. On a median Pacific Palisades sale of $4,260,775 in the 30 days to October 1, 2026 (my market report), that reset is worth tens of thousands a year. I have worked this coastline for 18 years, and this is the cost buyers most often underestimate and sellers most often misexplain. Proposition 19 then changes the picture twice over: it lets owners aged 55 and older carry their old assessed value to a new home up to three times, and it sharply limits what a child inherits. Here is how both work at Westside prices.
How are property taxes in Los Angeles calculated?
As of 2026, your bill is the assessed value multiplied by the tax rate, and the assessed value is set when you buy (Los Angeles County Assessor). Proposition 13, passed by California voters on June 6, 1978, limits the general levy to 1% of assessed value and prohibits reassessment except on a change of ownership or new construction.
On top of that 1% sit voter-approved indebtedness and direct assessments, which fund schools, water districts, lighting, emergency services and similar. That is why the real figure is above 1% but, across most of the county as of 2026, at or under 1.25% (Los Angeles County Auditor-Controller).
The consequence for a buyer is blunt. The taxes shown on a listing are the seller's taxes, based on what they paid, possibly decades ago. Yours will be calculated from your purchase price. A neighbour who bought in 1994 and a buyer closing this month can own identical houses and pay wildly different amounts, lawfully and permanently.
What will my property tax be on a Westside home?
Run your purchase price against the rate, then treat the result as a floor. Here is the arithmetic across my markets at current medians:
Market | Median sale, 30 days to Oct 1 2026 | At 1% | At 1.25% |
|---|---|---|---|
Pacific Palisades | $4,260,775 | $42,608 | $53,260 |
Santa Monica | $3,440,000 | $34,400 | $43,000 |
Venice | $2,374,500 | $23,745 | $29,681 |

Illustrative only; your actual rate depends on the assessments attached to your parcel.
Two things that table does not show. Your exact rate depends on the direct assessments on your specific parcel, which vary block to block. And in your first year you will also receive a supplemental bill, which trues up the difference between the former owner's assessed value and your new one for the remainder of the tax year. It arrives separately, months after closing, and it surprises nearly every first-time California buyer.
After that, Proposition 13 limits annual increases in assessed value, which is why long-held Westside property carries such low bills and why those owners are reluctant to move. Which is exactly what Proposition 19 was aimed at.
What is Proposition 19 and who does it help?
Proposition 19 lets homeowners aged 55 or older, and severely and permanently disabled homeowners of any age, carry their existing taxable value to a replacement home anywhere in California, up to three times (California State Board of Equalization).
The mechanics matter:
The replacement home can cost up to 105% of the original's full cash value if purchased within the first year of the sale, or 110% within the second year, and the original base transfers intact (Board of Equalization, current as of 2026).
Buy above that and the base still transfers, with the excess value added on top. You are not disqualified for trading up, you simply pay on the difference.
Three transfers are allowed regardless of whether the owner previously used a transfer under the older Propositions 60, 90 or 110 (Board of Equalization).
For a Westside downsizer this is substantial. An owner who has held a Palisades or Santa Monica house for thirty years is sitting on an assessed value far below market. Before Prop 19, moving usually meant surrendering that. Now it can travel with them, and it can travel more than once.
If you have been staying put mainly because of the tax consequence of moving, that calculation is worth redoing. It is a frequent reason sellers list, and my Westside valuation guide covers how I price the sale side.
How does Prop 19 affect inherited property?
This is the half that costs families money, and it is poorly understood. As of 2026, Proposition 19 limits the parent-child and grandparent-grandchild exclusion to the transferred property's existing base year value plus $1,000,000 (Board of Equalization). Current market value above that combined figure is added to the base.
At Westside prices that allowance is quickly exhausted. Take a Palisades home with a long-held assessed value of $500,000 and a current market value near the $4,260,775 median for the 30 days to October 1, 2026 (market report). The excluded amount is roughly $1.5 million. The remainder is added to the base, and the heir's bill is calculated on a figure far closer to market than to what their parents paid.
There is a second condition that catches people: the exclusion applies to a principal residence, and the child generally must use it as their own principal residence. An inherited Palisades house kept as a rental or a second home does not qualify on those terms.
One piece of relief worth knowing. The Board of Equalization confirms an inherited property can serve as the "original home" for a Prop 19 base year value transfer, provided the heir owns and occupies it as a principal residence either at the time of sale or within two years of buying the replacement. So an heir who moves in can later carry that base elsewhere.
Trust and estate sales are a meaningful part of my practice, and the pattern I see is families discovering the $1,000,000 ceiling after the fact, when a decision made for sentimental reasons has become expensive (Board of Equalization, as of 2026). Model it before you decide, not after.
What should a buyer or an heir actually do?
Get the numbers before the decision, because almost every Prop 19 question has a deadline attached.
Buyers: calculate the tax on your purchase price, not the listing's figure. Budget 1% to 1.25% of what you pay as of 2026 (Auditor-Controller), and set aside a supplemental bill in year one.
Buyers: check the direct assessments on the specific parcel. They vary and they are public.
Owners 55 or older: model the transfer before you list. The 105% and 110% thresholds are tied to timing between your sale and your purchase (Board of Equalization, 2026), so sequence matters.
Heirs: value the property and the existing base together. The gap over base plus $1,000,000 (Board of Equalization, 2026) is the number that decides whether keeping it is realistic.
Heirs: decide early whether anyone will occupy it. Principal residence use is a condition, not a formality.
Take it to a professional. I will tell you what the property is worth and what the comparable sales support. A CPA or estate attorney should tell you what the tax consequence is.
If you are weighing where on the Westside to buy in the first place, what is considered the Westside lays out how differently these markets price.
Want the real number on a specific property?
The tax question usually arrives too late, when someone is already attached to a house or already grieving. It is much easier to answer in advance.
Send me the address, whether you are buying, downsizing or inheriting, and I will give you the market value and the comparable sales that support it, so your CPA has something real to work from. Call me at 310-595-5181 or get in touch here.

Frequently Asked Questions
How much is property tax on a $3,000,000 house in California?
In most of Los Angeles County, roughly $30,000 to $37,500 a year, based on the 1% general levy plus voter-approved debt bringing the total to around 1.25% (Los Angeles County Auditor-Controller). Your exact figure depends on the direct assessments attached to the parcel. Expect an additional one-time supplemental bill in your first year.
Why are my property taxes higher than my neighbour's?
Because Proposition 13 sets assessed value at the time of purchase and bars reassessment except on a change of ownership or new construction. A neighbour who bought decades ago is taxed on that era's value with limited annual increases. You are taxed on what you just paid. Identical houses, lawfully different bills, permanently.
What is a supplemental property tax bill?
A one-off bill covering the difference between the previous owner's assessed value and your new one, for the remainder of the tax year in which you bought. It arrives separately from the regular bill, often several months after closing, and it is the single most common property tax surprise for buyers new to California.
How many times can I transfer my property tax base under Prop 19?
Up to three times, for homeowners aged 55 or older or severely and permanently disabled, anywhere in California (Board of Equalization). Three transfers are available regardless of whether you previously transferred a base under Propositions 60, 90 or 110.
Does my child inherit my low property tax base?
Only partly. Proposition 19 limits the parent-child exclusion to the existing base year value plus $1,000,000, with market value above that added to the base, and the child generally must use the home as their principal residence. At Westside prices the $1,000,000 allowance is quickly used up, so an inherited Palisades or Santa Monica home often carries a far higher bill for the heir than it did for the parent.
Can I move and keep my low property taxes if I buy a more expensive house?
Yes, with an adjustment. If the replacement costs up to 105% of the original's full cash value within the first year of sale, or 110% within the second, the base transfers intact. Above those thresholds the base still transfers and the excess value is added on top, so buying up costs you tax on the difference rather than disqualifying you.
