Look Up and Pay San Joaquin County Property Taxes

This page helps users handle property tax tasks in San Joaquin County, California, including finding a tax bill, checking current-year tax information, making payments, and knowing when to contact the San Joaquin County Treasurer-Tax Collector.

The San Joaquin County current year property tax roll is available online for inquiry and payment by credit card, debit card, or E-Check. Some needs, such as lien or demand information, payment plans, unclear bill responsibility, or property tax questions, must be handled through the Treasurer-Tax Collector’s Office.

San Joaquin County property tax search and payment

Use the county’s online tax search to look up a property tax bill or payment information. The search page supports roll year selection and different search criteria, depending on what information you have available.

• Roll year
• Assessment number
• Fee parcel number
• Street address

For current payment information, select the current roll year. Historical roll-year results are for historical purposes only and are not current data.

• Open the San Joaquin County property tax search page.
• Select the roll year that matches the bill or payment period you need.
• Enter your assessment number, fee parcel number, or street address.
• Review the results before making any payment, especially when searching by fee parcel number.

Check the bill carefully: fee parcel search results may include unsecured property tax bills that may not be owed by the property owner.

Search tips for assessments, parcels, and addresses

An assessment number can be used to view a specific assessment, but that search may not show every outstanding assessment. A fee parcel number is the better option when you need a summary of current or delinquent fiscal year assessments that are outstanding or paid during the current fiscal year.

If you do not have your assessment or fee parcel number, contact the Treasurer-Tax Collector’s Office. The assessment number and fee parcel number are shown in the upper-left area of the property tax bill.

Address searches may work better when you shorten directional and street-type terms. For example, use “W” instead of “West,” and try the address without words such as Street, Road, Drive, or Lane.

Ways to pay San Joaquin County property taxes

San Joaquin County lists four payment paths for property taxes: online, by phone, by mail, or in person. The online option is available for inquiry and payment, but payment plans may not be started online.

• For online payment or a tax bill copy, use the county’s pay taxes or obtain a tax bill service.
• For phone payments, use your 12-digit assessment number from the tax bill and call (877) 777-3839.
• For mailed payments, make the check or money order payable to SJC TTC, include the payment stub, and write the assessment number on the check or money order.
• For in-person payments, use the Treasurer-Tax Collector’s Office at 44 North San Joaquin Street, Suite 150, Stockton, CA 95202.

Mailed payments must be received or postmarked by the United States Postal Service by the delinquent date. Commercial postage meter dates are not valid for determining the mailing date.

Payment fees and monthly payment options

Online and phone payments are processed by LexisNexis, a third-party service provider. Convenience fees are paid to the service provider, not San Joaquin County.

The limit for an individual E-Check payment is $500,000. If an E-Check payment fails because of incorrect bank information, insufficient funds, or another issue, it will not be re-deposited and a return fee will apply.

San Joaquin County also works with Easy Smart Pay for monthly payment options on current year secured property taxes. Easy Smart Pay is a private company, not a government agency, and the service is for taxpayers who do not have an impound or escrow account.

Secured property tax due dates

Secured property taxes are due in two installments. If a delinquency date falls on a weekend or holiday, the delinquency date moves to the next business day.

Failure to receive a tax bill does not excuse penalties. Annual secured tax bills are mailed on or before November 1 when taxes are due.

Penalties, defaults, and postmarks

If the first secured installment is not paid by 5:00 p.m. on December 10, or timely postmarked when mailed, a 10% delinquent penalty applies. If the second installment is not paid by 5:00 p.m. on April 10, a 10% penalty on unpaid taxes and a $10 administrative charge are added.

Secured annual or supplemental taxes that remain unpaid after June 30 become tax-defaulted. Defaulted taxes are subject to delinquent penalties, costs, a state redemption fee, and redemption penalties of 1.5% monthly interest beginning July 1. If taxes remain defaulted for five years, the property becomes subject to the Treasurer-Tax Collector’s power of sale.

USPS postmarks are legally recognized for mailed payments. Metered mail, pre-canceled stamps, Automated Postal Center stamps, and permit imprint mail may not receive a USPS postmark, so taxpayers are advised to mail early, obtain a hand-stamped postmark, or pay online.

Supplemental and unsecured property taxes

Supplemental taxes may be issued after a change in ownership or completion of new construction. Supplemental tax bills are mailed to the property owner, not to lending agencies, and may be separate from the annual property tax bill.

Supplemental taxes are due when the bill is mailed. A supplemental bill becomes delinquent on the last day of the month after the month in which the bill was mailed. If the bill is payable in two installments, the second installment becomes delinquent four months after the first installment’s delinquency date.

Unsecured property taxes are a lien against the assessee rather than the real property. Examples include boats, airplanes, business property, improvements on another person’s real estate, possessory interests, and some escape or supplemental assessments.

New owners and tax bill responsibility

New owners are responsible for property taxes that were not paid when escrow closed. Taxes may be prorated between buyer and seller during escrow, but that does not always mean the Treasurer-Tax Collector’s Office received payment.

If you are not sure whether an installment was paid through escrow, contact your title company. If you need to know which tax bills are still outstanding, call the Treasurer-Tax Collector’s Office.

Annual tax bills are mailed once a year by November 1 and include stubs for both installments. Depending on when the ownership change is placed on the tax roll, the bill may be sent to the previous owner or to the new owner.

Assessment appeals

Property taxes are based on assessed value. If you believe the assessed value is too high, the San Joaquin County Clerk of the Board handles Assessment Appeal Applications.

Each Assessment Appeal Application requires the Assessor’s Parcel Number or another property identifier. There is a $30.00 non-refundable processing fee for each application, with an exemption for single family, owner-occupied property with an assessed value of $150,000 or less.
