How Property Tax Works

Blaine County, Oklahoma operates under a property tax system that funds essential local services including schools, county government operations, emergency services, and infrastructure maintenance. The county follows Oklahoma's state property tax framework with a base assessment rate around 1% of assessed value, though actual effective rates vary significantly based on your specific location within the county due to special taxing districts such as school districts, municipal authorities, and fire protection districts.

For the 2025 tax year, Blaine County adopted Ordinance 24-3017, which increased the property tax levy by 1% over the previous year. Property owners should expect their tax bills to reflect this increase, with the exact impact depending on their property's assessed value and applicable tax credits. The county assessor's office is responsible for determining fair market value assessments, while the treasurer's office handles tax collection and payment processing.

When Are Property Taxes Due?

For the 2025/2026 tax year in Blaine County, property taxes are due in two installments:

Pro tip: If you pay through mortgage escrow, your lender splits these payments across your monthly mortgage. If you pay directly, set calendar reminders to avoid late penalties.
Section 4

Supplemental Tax Bills

Supplemental taxes in Blaine County are additional property tax bills issued when there are changes in property ownership, new construction completion, or property improvements that increase assessed value during the tax year. These supplemental assessments are prorated based on the number of months remaining in the tax year after the triggering event occurs.

For example, if you complete a $50,000 home addition in July, and your effective tax rate is 1.1%, you would owe a supplemental tax of approximately $275 ($50,000 × 0.011 × 6/12 months remaining). Supplemental tax bills are typically mailed within 30-60 days of the assessment change and have separate due dates from your regular annual property tax bill.

Escrow & Property Taxes

Most mortgage lenders in Blaine County require property tax escrow accounts to ensure timely payment of property taxes. Your lender collects 1/12 of your estimated annual tax bill each month along with your mortgage payment, then pays the county directly when taxes are due on December 22nd each year.

Lenders typically conduct annual escrow analyses and may adjust your monthly payment if tax amounts change significantly. You can verify your tax payments were received by checking with the Blaine County Treasurer's Office or viewing payment records online. If you pay taxes directly without escrow, ensure payments reach the Blaine County Annex Building by the December 22nd deadline to avoid late fees and interest charges.
