When Does LA County Mail Property Tax Bills: 2026 Timeline And Guide
Navigating property taxes in the most populous county in the United States requires strict adherence to statutory deadlines and billing cycles. For property owners in Southern California, understanding when the Los Angeles County Treasurer and Tax Collector mails property tax bills is vital for avoiding costly delinquency penalties and maintaining clear property titles.
The Official Los Angeles County Property Tax Mailing Schedule
The Los Angeles County Treasurer and Tax Collector operates under strict timelines mandated by the California Revenue and Taxation Code. While the fiscal year runs from July 1 through June 30 of the following year, the actual billing and payment process follows a distinct annual rhythm.
Property tax bills for the 2026-2027 fiscal year are traditionally generated and mailed out in early October. By statutory requirement, all secured property tax bills must be mailed by November 1. If you are a property owner and do not receive your bill by late October, proactive measures are required to ensure timely payment, as failure to receive a bill does not excuse a taxpayer from paying penalties.
Key Milestones in the 2026 Assessment and Billing Cycle
The journey of a property tax bill involves several distinct administrative phases handled jointly by the Los Angeles County Assessor and the Treasurer and Tax Collector.
- January 1: The lien date for the upcoming fiscal year. Assessed values for properties are legally established as of this exact moment.
- July 1: The official commencement of the new fiscal year.
- July through September: The Assessor finalizes the local assessment roll, and values are locked for tax calculation.
- October: The Treasurer and Tax Collector processes, prints, and officially mails the secured property tax bills to property owners.
- November 1: The absolute statutory deadline by which all bills must be placed in the mail.
- December 10: The delinquency deadline for the first installment of property taxes.
Breakdown of Secured Property Tax Installments and Deadlines
Los Angeles County divides annual property tax obligations into two separate payments, commonly referred to as installments. Each installment represents half of the total general tax levy, alongside any direct assessments, parcel taxes, or bonded indebtedness tied to the specific property.
| Installment Period | Coverage Window | Mailing Date | Due Date | Delinquency Penalty Date |
|---|---|---|---|---|
| First Installment | July 1 to December 31 | Early October 2026 | November 1, 2026 | December 10, 2026 (at 5:00 PM) |
| Second Installment | January 1 to June 30 | Billed with 1st Installment | February 1, 2027 | April 10, 2027 (at 5:00 PM) |
Important Operational Note: Los Angeles County does not mail a second, separate physical bill in the spring. The initial mailing in October contains two distinct payment stubs: one for the first installment and one for the second installment. Property owners must retain these stubs or utilize online account management tools to ensure the second payment is submitted accurately before the spring deadline.

What to Do If Your Tax Bill Does Not Arrive
Property owners frequently experience delayed mail, address discrepancies following a recent purchase, or lost documents. Relying solely on physical mail can result in severe financial penalties if a payment is missed.
If November arrives and your bill has not appeared in your mailbox, take immediate action using the following verification steps:
- Access the Online Portal: Visit the official website of the Los Angeles County Treasurer and Tax Collector. The portal allows users to search property tax records by entering the Assessor's Identification Number (AIN) or the property address.
- Verify Mailing Addresses: Ensure that the mailing address on file with the Los Angeles County Assessor matches your current residence. Address changes must be filed directly with the Assessor's Office, not the Tax Collector.
- Print Duplicate Bills: The online system enables property owners to download, view, and print official duplicate bills containing the exact barcodes and remittance information required for payment processing.
- Contact Customer Service: Call the Los Angeles County Property Tax customer assistance line to speak with a representative if system errors prevent digital access.
Understanding Supplemental and Unsecured Property Tax Bills
Beyond the standard annual secured property tax bills mailed in October, Los Angeles County issues secondary tax documents under specific circumstances. Confusing these separate bills with standard secured bills often leads to missed payments.
Supplemental Property Tax Bills
When a property undergoes a change in ownership or new construction is completed, the Los Angeles County Assessor recalculates the assessed value. This triggers a supplemental assessment. Supplemental bills are mailed out throughout the year—not on the standard October schedule. They reflect the difference between the prior assessed value and the new assessed value for the remainder of the fiscal year. These bills are separate from your regular annual secured property tax bill and must be paid independently, even if your mortgage company pays your regular taxes through an impound account.
Unsecured Property Tax Bills
Unsecured property taxes apply primarily to business personal property, boats, aircraft, and certain leased equipment located on real property. These bills are typically mailed earlier in the year, usually between March and July, and are due by August 31. Unlike secured taxes, unsecured taxes are tied directly to an individual or business entity rather than anchored as a lien against real estate.
Strategies for Managing Your LA County Property Tax Obligations
Proper organization ensures that property taxes are handled efficiently without the stress of last-minute financial scrambles or administrative penalties.
- Monitor Mortgage Impound Accounts: If your monthly mortgage payment includes an impound (escrow) account, your lender generally receives electronic data feeds and pays the property taxes directly. Verify with your loan servicer that they have received the billing data and are scheduled to disburse payments before the December and April deadlines.
- Beware of Scams: The Los Angeles County Treasurer and Tax Collector never calls taxpayers demanding immediate wire transfers, cryptocurrency, or prepaid gift cards over the phone. Always verify web addresses carefully to ensure you are interacting with official county domains ending in gov.
- Keep Records of Payment: Whether paying online via e-check, credit card, or mailing a physical check with the payment stub via the United States Postal Service, retain confirmation numbers and proof of mailing. For mailed payments, ensure the envelope is postmarked by the United States Postal Service on or before the delinquency date to avoid penalties.
Frequently Asked Questions
When exactly are LA County property tax bills mailed out?
Secured property tax bills are printed and mailed annually in early October, with a statutory completion deadline of November 1. Property owners should expect delivery during mid-to-late October.
Does LA County mail a separate bill for the second installment in the spring?

What should I do if I recently bought a home and have not received a tax bill?
New homeowners should check the online portal of the Los Angeles County Treasurer and Tax Collector immediately using their Assessor Identification Number. Because ownership transfers take time to process through county systems, the initial bill may have been mailed to the previous owner.
