The Tax Collector is responsible for the collection of Secured, Unsecured and Supplemental taxes.

Secured Taxes

If you do not receive your secured tax bill by November 10, please email the Tax Collector's Office or call 707-253-4312 to arrange for a duplicate, as failure to receive a tax bill does not relieve your obligation to pay.

If you have questions regarding the valuation or ownership of secured properties, please email the County Assessor’s department, or call the Assessor's Office at 707-253-4467.

Due Dates

The First Installment of taxes is due and payable on November 1st, and will become delinquent if not paid by 5 p.m., or the close of business, whichever is later, on December 10th; thereafter a 10% penalty will be added.

(If delinquency date falls on a weekend or holiday, the delinquency date is the next business date.)

The Second Installment of taxes is due and payable on February 1st, and will become delinquent if not paid by 5 p.m., or the close of business, whichever is later, on April 10th; thereafter a 10% penalty plus a $10 cost fee will be added.

Unsecured Taxes

The Napa County Treasurer-Tax Collector’s Office mails unsecured tax bills to taxpayers in late July. The tax bills are due on or before August 31st.

If you do not receive your tax bill by August 1st, please contact the Treasurer-Tax Collector’s Office at 707-253-4312 to arrange for a duplicate, as failure to receive a tax bill does not relieve your obligation to pay.

If you have questions regarding the valuation or ownership of unsecured properties, please email the County Assessor’s department, or call the Assessor's Office at 707-253-4467.

According to California State Law, the unsecured tax lien date is January 1 for the following fiscal year.

If you owned a boat / business / aircraft or occupied a possessory interest on January 1st, you are legally responsible for the total taxes due. Any proration of these taxes is strictly between buyer and seller.

If you sold the boat/business/aircraft or moved, please email the County Assessor’s department, or call the Assessor's Office at 707-253-4467
