Learn About California Property Tax Payment Dates

Understanding California Property Tax Payment Dates and Schedules

California property owners receive property tax bills twice per year, with specific payment dates that vary depending on when the county assessor's office processes the assessment. The state's fiscal year runs from July 1 to June 30, which means property taxes are divided into two separate installments rather than one annual payment. The first installment typically covers the period from July through December of the current fiscal year, while the second installment covers January through June of the following fiscal year.

The actual due dates for these installments are set by California law and are consistent across all 58 counties, though bills may arrive at different times depending on each county's mailing schedule. The first installment is generally due on November 1 and becomes delinquent on December 10 if unpaid. The second installment is generally due on February 1 and becomes delinquent on April 10 if unpaid. However, these dates can shift slightly if they fall on a weekend or holiday, in which case the due date moves to the next business day.

Understanding these payment dates matters because property taxes in California are based on the assessed value of the property at the time of sale or new construction, adjusted annually by no more than 2 percent per year. Most homeowners can expect to receive their property tax bill in the mail approximately 45 to 60 days before the due date. The bill itself contains important information including the property's assessed value, the tax amount owed, and specific instructions for payment. Property owners should mark these dates on their calendars to avoid late payment penalties and interest charges.

Practical takeaway: Write down the standard California property tax due dates (November 1 for the first installment and February 1 for the second) and add a reminder two weeks before each date to ensure payment is made on time.

How Property Tax Bills Are Generated and When They Arrive

Before a property owner receives a bill, several steps must occur within the county assessor's office. The assessor's office maintains records of all properties within the county and their assessed values. Once the assessed value is determined—either through a new purchase, new construction, or the annual 2 percent inflation adjustment—that information is sent to the county tax collector's office. The tax collector then calculates the amount owed based on the property's assessed value and the applicable tax rate for that area. This process typically takes several months, which is why bills are mailed well in advance of the due date.

Most counties in California mail property tax bills between July and September for the first installment and between December and January for the second installment. Some counties use electronic billing systems that allow property owners to view their bills online before receiving paper copies. A few counties have started offering paperless billing options where bills are delivered via email instead of standard mail. The timing of bill arrival varies by county and can also depend on whether the property is newly assessed or if there have been changes to the property value assessment.

When the bill arrives, it contains several key pieces of information: the assessed value of the property, the tax rate applied to that property, the total amount of property tax owed for that installment, the due date, and the delinquency date when penalties begin to apply. Bills also typically include instructions for paying by mail, online, phone, or in person at the county tax collector's office. Some bills include a payment envelope for mailing, while others direct property owners to pay online or contact the office for payment options.

Practical takeaway: Contact your county tax collector's office or check their website to learn when bills are typically mailed in your county, and set up a system to watch for arrival of both the first and second installment bills.

Payment Methods and Where to Send Your Property Tax Payment

California property owners have several options for paying their property taxes by the due date. The most traditional method is mailing a check or money order to the county tax collector's office, with the address listed on the property tax bill. When paying by mail, it is important to mail the payment early enough that it arrives before the delinquency date. The postmark date is generally not considered the payment date—the payment must be received at the tax collector's office by the due date. Most counties recommend mailing payments at least one week before the due date to account for mail delivery times.

Online payment options are now widely available across California counties. Most tax collector websites allow property owners to pay their property taxes using a credit card, debit card, or electronic bank transfer. Some counties charge a small processing fee for credit card payments, while electronic bank transfers and debit card payments may be free or have minimal fees. Online payment systems typically process instantly or within one business day, and property owners receive a confirmation number for their records.

In-person payment at the county tax collector's office is another option. Property owners can visit the office during business hours and pay with cash, check, money order, credit card, or debit card. Some counties also accept payments at satellite offices or authorized payment centers located throughout the county. Phone payments are available in many counties, where property owners can call the tax collector's office and provide payment information over the phone using a credit card or debit card.

A few things to keep in mind when making payments: property owners should always keep a receipt or confirmation of payment, whether paying by mail, online, phone, or in person. Payments should reference the property identification number (also called the parcel number or APN) to ensure the payment is credited to the correct account. Some payment methods may have cutoff times—for example, online payments submitted after 5 p.m. may not process until the next business day.

Practical takeaway: Visit your county tax collector's website now to identify which payment methods are available and which method you prefer to use, then bookmark the website and payment link for quick access when a bill arrives.

Delinquency Dates, Late Fees, and Penalties for Missed Payments

Understanding what happens when property taxes are not paid by the due date is important for property owners. Under California law, property taxes become delinquent if not paid by December 10 for the first installment or by April 10 for the second installment. Once a payment becomes delinquent, the property owner faces financial consequences that increase over time. A 10 percent penalty is assessed on any unpaid property tax amount when it becomes delinquent. This penalty is added to the total amount owed.

Beyond the initial 10 percent penalty, unpaid property taxes also accrue interest at a rate of 1.5 percent per month. This interest compounds monthly, meaning the longer the taxes remain unpaid, the more interest accumulates. For example, if a property owner owes $1,000 in property taxes and misses the delinquency date by several months, they could owe an additional $150 in penalties plus several months' worth of interest at 1.5 percent per month. These additional costs can add up quickly, making it important to pay taxes on time when possible.

If property taxes remain unpaid for five years or more, the county tax collector may initiate a tax sale process. In California, the process typically begins after properties are on the delinquent tax roll for five years. The county may then sell the property at a public auction or through other methods, and the proceeds are used to pay off the back taxes, penalties, and interest. This process represents a serious consequence that could result in loss of the property.

Some property owners face genuine financial hardship and cannot pay their property taxes on time. In these situations, contacting the county tax collector's office is important. Some counties offer payment plans or deferrals that may allow property owners to spread payments over time or delay payment temporarily. These options vary by county and have their own rules and requirements. The sooner a property owner contacts their tax collector's office about financial difficulties, the more options may be available.

Practical takeaway: If you are unable to pay by the delinquency date, contact your county tax collector's office immediately to ask about payment plan options rather than allowing penalties and interest to accumulate.

Special Situations: Escrow Accounts, New Purchases, and Property Changes

When a property is purchased using a mortgage loan, the lender typically requires the borrower to establish an escrow account (also called an impound account) to cover property taxes and insurance. In these cases, the property owner's mortgage payment includes an amount that goes into escrow to cover taxes and insurance, and the lender pays the property taxes directly to the county tax collector on the property owner's behalf. Property owners with escrow accounts do not receive property tax bills and do not make direct property tax payments themselves.
