Where and how to pay Santa Clara County property taxes
Santa Clara County property taxes are collected by the County Assessor-County Clerk-Recorder office. You can pay online through the county's official website, by mail, in person at their office, or by phone. Online payment is the fastest route and lets you see your balance immediately. Payments made online typically post within one business day.
The county accepts checks, money orders, credit cards, debit cards, and electronic bank transfers. If you pay by mail, send your payment to the address listed on your property tax bill — do not send it to a different county office. Payments received by the 10th of the month are usually credited that month; payments after the 10th may not post until the following month.
You can also set up automatic payments through your bank's bill-pay system, which lets you schedule payments in advance and avoid late fees. The county does not charge a fee for online payments made through their official portal, but credit card companies may charge a processing fee if you use a card.
Key Takeaways
- Pay online at the Santa Clara County Assessor-County Clerk-Recorder website to see your balance and get immediate confirmation of payment.
- Property taxes in Santa Clara County are due in two installments: the first half is due by December 10, and the second half is due by April 10.
- Payments postmarked by the due date are considered on time, even if they arrive after; mail payments early to avoid delays.
- Late payments trigger a 10 percent penalty plus interest, which accrues daily, so paying even a few days late costs money.
- If you cannot locate your bill or do not know your property tax account number, call the Assessor-County Clerk-Recorder office at 408-299-5500 to look it up.
Payment deadlines and penalties
Santa Clara County property taxes are split into two installments. The first installment covers July through October and is due by December 10. The second installment covers November through June and is due by April 10. Both dates are firm; if your payment is postmarked after the due date, a penalty applies.
A payment that arrives after the due date triggers a 10 percent penalty on the unpaid amount, plus interest that accrues daily at a rate set by the state (currently around 0.5 percent per month, though this varies). A $2,000 payment that is 30 days late will cost you roughly $200 in penalty plus interest. The longer you wait, the more the interest compounds.
If you miss a payment entirely and do not respond to notices, the county can file a tax lien against your property, which damages your credit and makes it harder to refinance or sell. The county can also begin foreclosure proceedings, though this typically happens only after a full year of nonpayment and multiple notices.
Finding your bill and account number
Your property tax bill is mailed by the county in late October for the first installment and late March for the second installment. The bill shows your property address, the amount due, the due date, and your assessor's parcel number (APN). If you do not receive your bill, it may have been lost in the mail, or your address on file may be outdated.
You can look up your bill online using the county's property tax search tool, which is free and does not require a login. Enter your property address or APN, and the system will display your current balance, payment history, and due dates. If you do not know your APN, you can search by address.
If you cannot find your bill online or need help, call the Assessor-County Clerk-Recorder office at 408-299-5500 during business hours (Monday through Friday, 8 a.m. to 5 p.m.). Have your property address or owner name ready. The office can email or mail a duplicate bill to you at no charge.
Online payment options and security
The official Santa Clara County website offers a secure online payment portal where you can pay with a debit card or bank account. To pay online, visit the Assessor-County Clerk-Recorder website, select the property tax payment option, enter your property address or APN, and follow the prompts. The system will show your balance and allow you to choose a payment date.
Payments made through the county's official portal do not carry a processing fee. However, if you use a third-party payment service or pay by credit card, that service may charge a fee (typically 2 to 3 percent of the payment amount). Always verify you are on the official county website before entering payment information; scams targeting property owners do exist.
The county's online system is encrypted and uses the same security standards as banking websites. Your payment is confirmed immediately, and you receive a receipt number via email. Keep this receipt for your records; it serves as proof of payment if there is ever a dispute.
Paying by mail or in person
If you prefer to pay by mail, write a check or money order payable to "Santa Clara County" and include your property tax bill or a copy of it with your payment. Mail it to the address printed on your bill, which is typically the Assessor-County Clerk-Recorder office in San Jose. Do not send cash through the mail.
Payments must be postmarked by the due date to avoid a late penalty. If you are mailing close to the deadline, consider using certified mail or a service that provides tracking, so you have proof of the postmark date. The county processes mail payments within 5 to 10 business days after receipt.
You can also pay in person at the Assessor-County Clerk-Recorder office, located at 70 West Hedding Street, San Jose, CA 95110. The office accepts cash, checks, money orders, and card payments. Hours are Monday through Friday, 8 a.m. to 5 p.m. In-person payments are posted the same day.
What to do if you cannot pay on time
If you know you cannot pay by the due date, contact the Assessor-County Clerk-Recorder office as soon as possible. The county does not offer formal payment plans or deferrals for property taxes, but calling ahead shows good faith and may help if you are working toward a solution. Ignoring the bill will not make it go away and will only increase the penalty and interest owed.
Some property owners are may be able to access for property tax relief programs based on age, disability, or income. The county's Assessor's Office administers these programs and can tell you whether you may have access to. These programs do not eliminate your tax bill but may reduce it or defer payment. Call 408-299-5500 to ask about relief options for your situation.
If you are facing foreclosure or have already received a notice of default, contact a HUD-approved housing counselor or a legal aid organization in Santa Clara County. These organizations can sometimes negotiate with the county or help you understand your options. The longer you wait, the fewer options remain.
Frequently Asked Questions
What happens if I pay late?
A 10 percent penalty is added to your unpaid balance, plus daily interest. The interest rate is set by California state law and changes annually. If your payment is even one day late, the penalty applies immediately. The longer you wait, the more interest accrues, so paying as soon as possible after the deadline is better than waiting longer.
Can I pay my property taxes with a credit card?
Yes, but only through third-party payment processors, not through the county's official portal. Third-party services charge a processing fee (usually 2 to 3 percent), which is added to your bill. Paying by debit card or bank transfer through the county's official website avoids this fee.
What if I own property in Santa Clara County but live out of state?
You can pay online from anywhere using the county's website, or you can mail a check to the address on your bill. Online payment is faster and gives you immediate confirmation. If you want to set up recurring payments, ask your bank's bill-pay service to send a check automatically each year before the due date.
How do I know if my payment was received?
If you paid online, you receive a confirmation number and receipt immediately. If you paid by mail, wait 10 business days, then check your balance online or call 408-299-5500 to confirm the payment posted. If you paid in person, ask for a receipt before you leave the office.
Can I pay someone else's property taxes?
Yes. You do not have to be the property owner to pay the bill. Provide the property address or APN and the amount due, and you can pay online or by mail. The payment will be credited to that property's account regardless of who submits it.
