How to Pay Your Property Taxes

This service is for public access and is available for personal use only. To protect your privacy, we do not display an owner's name in the result of any searches you perform on this page.

Assessment vs. Fee Numbers

Your tax bill shows both an assessment (ASMT) number and a fee number. Use of the ASMT number displays that specific tax bill only. The fee number will display all tax bills associated with this property, including supplemental tax bills and defaulted tax years. We recommend using the fee number for online payments.

To access your property tax information, only enter one "Search Criteria" in the corresponding row of the chosen field: assessment number, fee parcel number or property address. For questions about your property taxes, please contact the Tax Collector's office at 707-253-4312.

If you do not receive a confirmation number at the end of your transaction, your transaction was not successful.

A good way to pay your tax bill is by mail. In the envelope containing your tax bill you will find a preaddressed envelope for each installment due. Attached to the bottom of your tax bill you will find payment stub(s) for each installment. Simply include your payment and the payment stub(s) for which installment(s) you wish to pay in the preaddressed envelope, add postage and place in the mail. Using the preaddressed envelopes will ensure prompt handling of your payment once received. Please make checks and money orders payable to the Napa County Tax Collector and write the Fee Parcel Number on them. Your canceled check or money order stub serves as your receipt. Never send cash.

Be sure to mail payments early so that your envelope is postmarked before the delinquent date. A postmark date and time is acceptable proof of timely payment.


You may also come to the Napa County Tax Collector's office, located at 1195 Third St Ste 108 Napa CA, between the hours of 8:00 a.m. and 5:00 p.m., Monday through Friday (except major Holidays).

This box is emptied at 5:00 p.m. every business day, and payments are processed the following business day. Payments must be received prior to 5:00 p.m. on the day that they are due, or they will be considered delinquent.


To make payments by telephone, please call 1-855-627-2121. Please note that the payment processing company charges a 2.32% transaction fee for credit or debit card payments but NO transaction fee for E-check payments.
