The deadline to pay Sarasota County property taxes in Sarasota County is Saturday. Payments must be made online, in-person, or postmarked by the weekend. Those who waited until the last minute missed out on rolling discounts- taxpayers get 4% off if they paid in November, 3% in December, and so on until the due date. After Easter, taxes will be considered delinquent and subject to a 3% penalty.
