Ottawa County Overview
Ottawa County Treasurer - Payments and Tax Rolls
The Ottawa County Treasurer serves as the county's chief financial officer and handles all property tax collection. The office is located at the Ottawa County Courthouse Annex, 123 E Central Ave, Miami, OK 74354. The treasurer's main line is 918-542-8232. Tax statements are mailed each November or early December. If you do not receive a statement by early December, contact the office to request one. You are still responsible for payment on time even if the statement never arrives.
Ottawa County follows Oklahoma's standard two-installment schedule. Taxes of $25.00 or more may be paid in two halves. The first half must be paid by December 31. The second half is due by March 31 of the following year. Penalty accrues at 1.5% per month on any amount not paid by the deadline. The county's online tax portal is at oktaxrolls.com/county/ottawa. This is the official site for payments and tax roll lookups.
The treasurer's office also manages the annual tax resale. The June 2026 resale is scheduled for Monday, June 8, 2026, at 9:00 AM at the courthouse annex. Winning bidders at the resale pay the bid amount plus a $20.00 deed filing fee and a $10.00 deed prep fee. Properties end up on the resale list after taxes have been unpaid long enough for the county to take action under state law. If your property is at risk of appearing on the list, call the treasurer's office before the resale date to resolve the balance.
Note: Ottawa County tax statements are mailed in November; contact the treasurer at 918-542-8232 if you have not received yours by early December.
Ottawa County Assessor - Property Valuation
Assessor Becky Smith manages all property valuation in Ottawa County. The assessor's office is at the Ottawa County Courthouse in Miami and can be reached at 918-542-9418. The assessor sets the fair cash value for all real and personal property in the county. Under Oklahoma Title 68, real property is assessed at 11% of that fair cash value. The assessor does not collect taxes; that is the treasurer's role. The assessor simply determines the value that the levy rate is applied to.
County Clerk Robyn Mitchell can be reached at (918) 542-3332. The clerk's office maintains recorded land instruments including deeds, mortgages, plats, and oil and gas leases. These records work alongside the assessor's ownership data to give a full picture of any parcel's history and current status. If you are doing a title search or need to verify chain of ownership for a property in Ottawa County, the clerk's records are your starting point.
