Property Tax
Santa Clara County property tax services help owners view tax bills, identify payment deadlines, pay the correct account, and address penalties or unclaimed refunds. This article explains the differences between secured and unsecured property taxes, the information needed to use County payment systems, available payment methods and fees, and procedures for parcel tax exemptions and penalty cancellation requests.
Which Office Handles Property Taxes?
The County’s Department of Tax and Collections, commonly called DTAC, provides property tax billing and collection services. Its property tax services include online bill access, payments, penalty cancellation requests, and claims for unclaimed property tax refunds. The department has separate service pages for secured and unsecured taxes, so identifying the type of bill is the first step toward using the correct system.
Payment and collection questions are different from questions about an assessed property value. DTAC’s property tax pages direct users to the County Assessor for assessment information. A question about paying a bill, a returned payment, or a late-payment penalty belongs with DTAC’s tax services. A concern about the value assigned to property should be directed through the Assessor resources identified on the County’s tax pages.
Special assessments require another distinction. A school district, city, or other assessment district may offer an exemption from a particular charge. Those exemptions depend on the agency responsible for that assessment. An exemption offered by one district should not be treated as an exemption from every charge on a property tax bill.
Secured and Unsecured Tax Bills
Homes, Buildings, and Land
DTAC identifies homes, buildings, and land as secured property. The County’s secured property tax information page provides access to viewing and paying these taxes. To locate the property for payment, have either the Assessor’s parcel number, usually abbreviated APN, or the property address available.
The APN is a parcel identifier. It serves a different purpose from the assessment number or Assessor’s account number used for unsecured property. When reviewing a bill or an online result, compare the property information with the property you intend to pay for before submitting a transaction. This is especially useful when handling more than one parcel or making payments for multiple properties.
Businesses, Boats, and Airplanes
The County identifies businesses, boats, and airplanes as examples of unsecured property. Its unsecured property tax information page lists the information used to locate these taxes: an assessment number, an Assessor’s account number, a business name, or a business address.
Use the unsecured service when the bill concerns this category of property. Do not assume that a business-related bill can be located through a secured parcel search simply because the business operates at a street address. Match the tax category and identifying information on the bill to the corresponding County service.
The two categories also follow different annual payment calendars. Secured taxes have first and second installment dates. Unsecured bills are mailed in July and are due upon receipt, with a separate deadline for avoiding penalties.
Property Tax Dates and Deadlines
The County identifies January 1 as the lien date, meaning the day the property’s value is assessed. That date is separate from the mailing date, payment due date, and delinquency date. Keeping these dates distinct helps prevent confusion when reading a tax bill.
Secured Tax Installment Calendar
Annual secured property tax bills are mailed in October. The first installment is due November 1, and December 10 is the last day to pay that installment without penalties. The second installment is due February 1, and April 10 is the last day to pay it without penalties.
The County also identifies June 30 as the last day to pay the current year’s taxes without additional penalties. This does not replace the December 10 and April 10 deadlines. A payment made after an installment’s delinquency date may already be subject to penalties, even if it is made before June 30. Read the bill’s notes about penalties, fees, and the consequences of paying late.
Unsecured Tax Payment Calendar
Unsecured property tax bills are mailed in July and are due upon receipt. August 31 is the last day to pay unsecured taxes without penalties. Unlike the secured calendar, the published unsecured calendar does not divide the annual bill into the November and February installments.
If December 10, April 10, or August 31 falls on a weekend or County holiday, the delinquency date extends to the next business day. This extension applies to the dates specified by the County. When preparing a payment, compare the calendar with the deadline shown on the particular bill.
Online Payments and Account Features
The County’s bill payment page provides access to property tax payment options, including online, mail-in, phone, and in-person payments. The property tax payment site includes a user profile feature for securely storing payment methods and a shopping cart feature for paying tax bills for multiple properties in one transaction.
Before using the online service, gather the bill and the appropriate property identifier. For secured taxes, that means the APN or property address. For unsecured taxes, have the assessment number, Assessor’s account number, business name, or business address available. When paying several properties together, review each selected bill and its identifying information before completing the transaction.
The online payment site is unavailable every third weekend of the month from 8:00 a.m. Saturday through 5:00 p.m. Sunday, Pacific Time. Plan around this scheduled interruption, particularly when arranging a payment close to a delinquency date. The maintenance period is a published limitation of the online system and should be considered when choosing when to submit a payment.
Card Fees and eCheck Payments
The secured tax service accepts major credit cards, debit cards, and eChecks. The unsecured tax service identifies major credit cards and eChecks as online payment options. DTAC’s published online card fee is 2.22% of the transaction amount, with a minimum charge of $1.49 per transaction. There is no fee for an eCheck payment.
Review the payment method and associated charge before submission. The absence of an eCheck transaction fee does not remove the need to enter accurate banking information. Confirm the account and routing numbers used for the payment, and validate card information when choosing a credit or debit card.
Returned Payments and Additional Charges
The secured property tax page states that an $85 returned payment fee applies when a check, eCheck, or credit or debit card payment is returned unpaid by the financial institution for any reason. Additional penalties and fees may apply if a replacement payment is submitted after the delinquency date.
An attempted payment and a completed payment are therefore different matters. Incorrect account information can prevent the payment from being honored. DTAC also identifies errors entered by taxpayers in the online portal as a reason it will deny a penalty cancellation request. Reviewing payment details before submission can help avoid both a failed transaction and a later dispute over penalties.
Mailed Payments and USPS Postmarks
For mailed tax payments, the United States Postal Service cancellation postmark has a specific role in determining whether a payment was timely. DTAC explains that an official USPS postmark is distinct from a private postage meter date. A postage meter mark shows that postage was paid; it does not establish when USPS took custody of the envelope.
A statement that a payment was mailed early enough to arrive before the deadline does not, by itself, support penalty cancellation. The department relies on the applicable USPS cancellation mark. When mailing a payment near a deadline, pay attention to the postmark requirements rather than relying only on the date the envelope was prepared.
Payments initiated through a bank’s bill-pay service present another issue. DTAC explains that envelopes used for home banking and online bill payments are not postmarked by USPS. Without a postmark, the department uses the date it receives the payment to determine whether it is late. Initiating a bank bill payment before the delinquency date does not establish that DTAC received it on time.
The County’s own online tax payment portal and a bank’s online bill-pay service are separate payment methods. The distinction matters when considering delivery time and proof of timeliness. Review the County’s payment instructions for the method you select.
Office Visits and Payment Drop Box
DTAC’s office location and operating information identifies office hours as Monday through Friday, 8:00 a.m. to 5:00 p.m. Phone hours are Monday through Friday, 9:00 a.m. to 4:00 p.m. The department is closed on County holidays.
The property tax payment drop box is inside the building, in the east wing on the first floor. It is available during normal business hours, Monday through Friday from 8:00 a.m. to 5:00 p.m. Do not deposit cash in this drop box.
The department also handles other types of collections and identifies different drop locations for some of those services. For a property tax payment, use the property tax drop box identified by DTAC. Bring the bill or relevant account information so the payment concerns the intended property tax account.
Billing Reminders and Paperless Delivery
Through the County’s electronic notification service, taxpayers can sign up for property tax updates and reminders about upcoming due dates. Homeowners can also opt in to paperless billing to receive property tax bills by email.
Email reminders and paperless bills serve different purposes. Reminder newsletters provide deadline information and department updates, while paperless billing delivers the property tax bill electronically. Choose the service that matches how you want to receive tax information.
A missing bill should prompt a review of the tax account rather than a delay in payment. DTAC expressly identifies nonreceipt of a property tax bill as a reason it will deny a penalty cancellation request. Its tax pages also provide access to a mailing address change service. If billing correspondence is going to the wrong address, use that service to address the mailing information.
Supplemental Bills and Partial Payments
A supplemental tax bill, a partial payment, and a formal installment plan each involve questions beyond the standard annual calendar. DTAC’s property tax questions page organizes these topics separately, along with secured and unsecured tax questions.
The supplemental tax topics include when bills are due, when they become delinquent, why more than one supplemental bill may be issued, and how supplemental billing relates to an annual bill. The page also addresses questions involving mortgage impound accounts. If your question involves a supplemental bill, consult the supplemental tax material rather than assuming the annual secured installment dates answer it.
For partial payments, the County provides separate questions about current secured taxes, prior-year redemption bills, remaining balances, overpayments, and penalties. It also addresses Installment Plans of Redemption and Escape Payment Plans. Before making a payment smaller than the amount due, consult the material for the specific bill or plan. A partial payment should not be assumed to satisfy an installment obligation or preserve a payment plan.
Property Tax Penalty Cancellation Requests
The County’s penalty cancellation procedure applies to penalties assessed on secured or unsecured property tax bills. DTAC may cancel penalties only for reasons authorized by the California Revenue and Taxation Code. Submitting a request does not establish that a penalty will be removed.
The department requires payment in full before reviewing a penalty cancellation request. The penalty must first be paid. If cancellation is approved, the taxpayer receives a refund. A request must include a completed and signed form, the required payment, and supporting documentation.
Information Required for a Request
The form requires contact information, a mailing address, tax bill information, and the APN or assessment number. Explain in detail why the circumstances support cancellation under the provisions identified by DTAC. Attach documents supporting that explanation, then sign and date the form.
Requests can be submitted online or by mail using the options on the County’s penalty cancellation page. The department states that a decision may take up to six months. Prepare the documentation before submitting the form so the request includes the information required for consideration.
Reasons the County Will Deny
DTAC identifies several circumstances that do not authorize cancellation. These include financial hardship, a history of timely payments, failure to receive a bill, and a new homeowner’s unfamiliarity with the property tax process. A private postage meter date or an unsupported assertion that a payment was mailed in time also does not establish a qualifying basis.
The department additionally identifies late-arriving bank bill payments and taxpayer errors in online payment information as reasons for denial. Review these restrictions before preparing a request, particularly if the problem involved an incorrect routing number, account number, or card information.
The County also identifies potentially qualifying grounds, including proof of a timely USPS cancellation postmark, substantial evidence that payment was mistakenly made on another property, and specified County errors. Certain circumstances beyond the taxpayer’s control may qualify under the stated requirements. Examples include unexpected hospitalization on the delinquency date, natural disasters, the property owner’s death on or before the delinquency date, and a government-declared state of emergency. Supporting evidence and the applicable statutory requirements remain part of the review.
Parcel Tax Exemptions and District Charges
The County’s parcel tax exemption directory identifies assessment districts that may offer exemptions to eligible taxpayers. The directory connects a special assessment number and description with the responsible district’s exemption and application information.
Possible eligibility categories include taxpayers age 65 or older, people receiving Supplemental Security Income for a disability regardless of age, and people receiving Social Security Disability Insurance benefits whose annual income meets the specified limit. These are possible categories, not a Countywide guarantee of exemption. The responsible district determines the requirements for its assessment.
Match the special assessment number and measure description on the bill to the directory entry before pursuing an application. Some agencies offer income-based senior exemptions, and application periods and renewal requirements vary. The directory identifies annual renewal for the Santa Clara Valley Water District senior exemption, while some other entries identify a one-time exemption.
The SF Bay Restoration Authority entry has a particularly different limitation: its exemption is available only for qualifying contiguous parcels. The County expressly states that this entry has no senior or low-income exemptions. Review the particular assessment’s requirements rather than applying another district’s eligibility rules to it.
Claims for Unclaimed Property Tax Refunds
The County’s unclaimed property tax refund search allows users to search by name and review entries showing the payee name, APN, refund amount, and claim action. Compare the payee and parcel information with your records before selecting an entry to claim.
Property tax refunds can result from reduced assessments, overpayments, and duplicate payments. They may become unclaimed because of returned mail, uncashed checks, refusal of funds, or a lack of response to notifications. This service concerns existing unclaimed refunds; it is separate from submitting a penalty cancellation request.
The required claim documents are:
Government-issued photo identification, such as a driver’s license, identification card, or passport.
Proof of ownership for the APN shown in the refund entry.
A notarized limited power of attorney if filing for someone else.
An electronic claim cannot be completed without uploading the required documents in DocuSign. People unable to file electronically can download the County’s PDF claim form and mail it with the required documentation to DTAC’s Fiscal Division–Property Taxes.
The County states that claim review may take 45 to 60 days, depending on claim volume. Funds remaining unclaimed for more than two years are removed from the list and transferred to the County’s general fund under Government Code section 29802. Review a matching entry and assemble the required ownership and identification documents before filing the claim.

Property Tax FAQs
Can I schedule a property tax payment?
Yes. The Department of Tax and Collections announces that scheduled payments are available through its property tax portal. Before choosing a payment date, open the scheduling FAQs linked from the County’s tax department homepage to review how the feature works. Check the installment you intend to pay and its delinquency date before scheduling. Keep the scheduling confirmation, and check your account afterward to verify that the payment was completed; setting a future payment date is a separate step from completing the payment.
Why does my bill include garbage or sewer charges?
For San Jose properties, garbage and sewer assessments can appear among the charges addressed through the County’s property tax services. When a question concerns one of these charges, identify the assessment description on your bill rather than treating the entire balance as a single assessment. The County’s special assessment information includes a dedicated option for City of San Jose garbage and sewer assessment questions, along with special assessment contacts. Use the option matching the charge you are questioning.
Where can I check my property tax rate?
The County’s secured property tax information page provides access to its property tax rate book and information about tax rates and tax rate areas. Have your bill available when reviewing those materials so you can compare the applicable rate information with the listed charges. Review special assessments separately: a question about a district charge may require different information from a question about the property tax rate.
How can I check a suspicious tax letter?
The secured property tax information page includes a “Scam Letters” option for questionable correspondence. Start there before following payment instructions in an unexpected letter. Independently open the County’s official bill payment page to review your tax account. Compare the property and bill information with your records before submitting a payment.
