LA County Property Taxes: What Homeowners Should Know Before the First Installment

Every fall, homeowners across Los Angeles County receive their annual property tax bills, and the first installment is due soon. For new homeowners especially, property taxes can be confusing — how they're calculated, when they're due, and why a second bill sometimes arrives after you buy. Here's a clear overview of LA County property taxes and what homeowners in Glendora, Pasadena, and across the county should know. For questions about your specific bill, contact the LA County Treasurer and Tax Collector or the LA County Assessor.

When are LA County property taxes due?

Annual secured property tax bills are paid in two installments. The first installment is due November 1 and becomes delinquent if not paid by 5 p.m. on December 10. The second installment is due February 1 and becomes delinquent after April 10. When a deadline falls on a weekend or holiday, it moves to the next business day. Late payments carry a 10% penalty, so it pays to mark your calendar.

If your mortgage includes an escrow or impound account, your lender typically pays the bill for you — but it's still worth confirming the payment was made.

How is your property tax bill calculated?

Under Proposition 13, your property's assessed value is generally set at its purchase price, and the basic tax rate is 1% of that value. Each year, the assessed value can increase by no more than 2%, unless there's a change in ownership or new construction. On top of the 1% base, your bill includes voter-approved bonds and local assessments for things like schools, water, and community services, which is why the total rate is usually somewhat higher than 1% and varies by neighborhood.

What is a supplemental property tax bill?

This surprises many new homeowners. When you buy a home, the property is reassessed to its purchase price. If that's higher than the previous owner's assessed value, the county issues a supplemental bill to cover the difference for the rest of the fiscal year. These bills are usually mailed directly to the owner, not to the lender, even if you have an impound account. We always tell our buyers to expect one or more supplemental bills in the months after closing and to set money aside for them.

How can homeowners lower their property taxes?

The Homeowners' Exemption reduces the assessed value of your primary residence by $7,000, which saves roughly $70 or more per year. It's modest, but it's easy to claim, and many new owners forget to file. The form is available from the LA County Assessor.

If you believe your home's market value has fallen below its assessed value, you can request a decline-in-value review from the Assessor, typically during an annual filing window that runs through November 30. There are also exclusions and exemptions for seniors, people with disabilities, disabled veterans, and certain family transfers, including those under Proposition 19. The Assessor's website lists current programs and deadlines.

What should buyers know about property taxes before purchasing?

When budgeting for a home, don't base your estimate on the seller's current tax bill — it may reflect a much lower assessed value from years ago. Instead, estimate taxes based on your purchase price and the local tax rate, and ask your agent or lender about any special assessments, such as Mello-Roos districts, that may apply. Knowing your real property tax cost helps you compare homes accurately and avoid surprises after closing.

How can you pay your property tax bill?

The LA County Treasurer and Tax Collector offers several ways to pay, including online payment by electronic check or credit card, payment by mail, and payment in person. Card payments typically carry a processing fee, so many homeowners prefer electronic checks. If you mail your payment, make sure it's postmarked by the delinquency date. Keep a record of your payment confirmation, and check the Treasurer and Tax Collector's website to confirm your payment was received.

If you're having difficulty paying, contact the Treasurer and Tax Collector's office as soon as possible to learn about available options. Unpaid property taxes can lead to additional penalties over time, so addressing a problem early is always best.
