Tax payments (after February 1st that are delinquent or postponed) can be made by credit card at www.officialpayments.com or 1-800-272-9829; the jurisdiction code for Marathon County is 5853. There is a service fee from the company for 3% of the payment amount. It will be told to you before you complete the process; you can stop and not submit the payment. The payment information is e-mailed to the treasurer and the money transfer is done interbank. The Marathon County Treasurer’s Office will produce a receipt and mail it to you, the same as payments received by mail.
Tax bills are mailed by your local government after budgets are set, and rates are calculated. This is usually during the first 2-3 weeks in December.
