Avoiding Penalties
To avoid penalties plan ahead and make necessary arrangements in advance.
If you are mailing your payment it must be postmarked no later than delinquent date to be considered timely. To make sure the postmark is correct, deliver your envelope in person to the post office and ask them to stamp it with the current date.
If you are paying through our website, make sure you are entering the correct account information and have funds available in your account before completing the transaction.
Submitt Online and Check payments early. If a payment is returned after the due date, additional tax penalties may apply.
Visit our Paying Your Taxes section for other ways to ensure your payment is received on time. Or contact the Tax Collector's Office at (707) 565-2281 with any additional questions.
