Pay Your Property Taxes By Mail
Important Notice
The due dates for tax payments are printed on the coupons attached to the bottom of the bill. Full payment must be made by the due date in order to be credited on time. No partial payments will be accepted. Payments for less than the amount due at the time of payment will be returned to the maker. A penalty and administrative cost will be assessed for payments received late.
Mail your check using the return envelope provided with your bill. Do not send cash! Payments must be for the full amount on the stub. The first stub must be used for payment before the second stub. Send both stubs if paying the entire bill at one time.
If sending multiple checks for payment, the total must equal the amount due and all checks must be enclosed with the stub(s) in the same envelope. Send only the payment coupon with your check. Keep the remainder of the tax bill for your records. Please do not staple, fold, paper clip, tape, or glue the check to the coupon nor write on the coupon.
If you do not have a tax bill, but know the parcel number or assessee account number, you may mail a payment without an original tax bill as long as the parcel number or assessee account number is on the face of the check(s). You may also use the stubs from the printed bill after searching for your parcel number under Account Lookup. Always use the original stubs if they are available.

Alameda County Treasurer & Tax Collector
1221 Oak Street, Room 131
Oakland, CA 94612
Make checks payable to:

Your canceled check is your receipt. Within a week, verify that your check clears with your bank. In addition, verify the posting of your tax payment at this website by clicking on "Account Lookup" and entering the parcel number or assessee account number.
IMPORTANT NOTICE REGARDING YOUR MAILED IN PAYMENT:
The United States Postal Service has changed its regulations regarding postmark dates as of December 24, 2025. The postmark date will be the date the item is first processed by its automated processing equipment, not the date it is picked up from the mailbox. You must make sure to submit your payment well before the deadline or you must walk into your local post office and request a manual postmark date to be added onto your payment. You can avoid all of this by simply paying online. Your e-check payment is free of charge and will save you time and postage. We strongly encourage you to use this option as we will honor the new postmark date as receipt date.
