Property tax bills for the current year will be mailed by the end of September. The first installment of Humboldt County Property Taxes is due November 1 and MUST be paid by Monday, December 11, 2017 in order to be considered timely. Payments received after that date will result in a 10% penalty. If mailing, make sure your payment is postmarked by December 11th or else you will be penalized. The second installment will be due February 1 and MUST be paid by Monday, April 10, 2018 in order to be considered timely. Payments received after that date will result in a 10% penalty and a $ 20 fee. If mailing, make sure your payment is postmarked by April 10th or else you will be penalized. We urge anyone having questions regarding payment to first look at your tax bill, front and back, or check out the website http://humboldtgov.org/tax as almost all answers can be found in one of these two places. If you don’t find your answer then call us, the Assessor, or the Auditor (depending on your question) at 707-441-3020. Online payments can be made at the website http://humboldtgov.org/tax or at the Tax Collector’s office where we also accept debit card, credit card, and e-check payments. This added convenience does involve processing by private companies so there is a service fee charged by these outside contractors (not by Humboldt County). You may also make debit and credit card payments over the phone by calling (877) 486-7163….and yes, the same service fees apply. There are also secure tax payment boxes just inside the Courthouse (before the security check-points) at both the 4th and 5th Street entrances. Keep in mind that the Courthouse closes at 5:00. The Tax Collector's Office will be very busy through December 11th. So if you wish to pay in person you will not only need to go through Courthouse security screening but may also have to wait in line once you get to the Tax Collector’s office. Mailing your payment early will be less of a hassle.
