Los Angeles County Property Tax Calculator
Los Angeles County's property tax bill starts with Proposition 13: the county assessor sets a base value when a home last changed hands, and state law caps how much that value can climb each year until the next sale resets it. The Los Angeles County Assessor administers this across a strikingly wide range of neighborhoods, from beachfront blocks to inland desert towns, so two owners paying the same rate can owe very different amounts once their assessed values diverge.

Property tax in Los Angeles County, California
- The Los Angeles County Assessor establishes each property's assessed value, which under Proposition 13 can only rise by a capped amount annually unless the property is sold, remodeled significantly, or otherwise reassessed.
- A change in ownership or completed new construction triggers reassessment to current market value, which is why longtime owners often pay noticeably less than a neighbor who bought recently.
- An owner-occupied home whose assessed figure looks off the mark can be challenged before the county assessment appeals board rather than accepting the assessor's number as final.
- A homeowners' exemption shaves a modest amount off assessed value for an owner-occupied primary residence, stacking on top of whatever Proposition 13 has already capped.

Frequently asked questions
How is property tax calculated in Los Angeles County?
The Los Angeles County Assessor determines your property's assessed value under Proposition 13 rules, then voter-approved local levies for schools, community colleges, and special districts are applied on top of the base county rate. Because the assessed value is tied to your purchase price and capped growth rather than current market value, your bill can differ sharply from a neighbor's even on an identical home.
How do I appeal my Los Angeles County assessment?
The county's assessment appeals board hears the case if an owner disagrees with the assessor's figure; file within the annual window and bring comparable sales as backup. Many owners first try an informal chat with the assessor's office, which resolves plenty of disputes before a hearing is ever needed.
Does Los Angeles County offer a homestead exemption?
Yes — California calls it the homeowners' exemption, and it trims a bit more off the taxable figure for an owner-occupied home. That's on top of whatever Proposition 13 already limits year over year.
Why did my Los Angeles County tax bill jump after I bought my home?
Because Proposition 13 resets assessed value to the purchase price at the moment of sale, buyers frequently step into a materially higher assessed value than the seller had built up over years of capped annual increases. From that new baseline, future growth is capped again going forward, so the jump is a one-time reset rather than an ongoing trend.
