Rate Breakdown

Property taxes in Tulsa County are calculated by multiplying the assessed value (minus exemptions) by the total local millage rate.

How Property Tax Works in Tulsa County

Property taxes in Tulsa County are based on the "ad valorem" system, meaning taxes are calculated according to the value of the property. The process begins with the Tulsa County Assessor, who determines the fair market value of your property. In Oklahoma, the taxable value is typically a percentage of this market value.

Once the value is established, the tax amount is determined by the millage rate. A "mill" represents one-tenth of a cent per dollar of assessed value. These rates are set by various local taxing jurisdictions, including the city, county, and local school districts. To calculate your estimated tax, the total millage rate is applied to your property's assessed value.

Available Exemptions

Oklahoma offers several exemptions designed to reduce the tax burden for eligible homeowners. Applying for these exemptions can significantly lower your annual property tax bill:

• Homestead Exemption: Available to homeowners who use the property as their primary residence. This provides a significant reduction in taxable value and caps the increase in assessed value for the home.
• Senior Citizen Exemption: Homeowners aged 65 or older may qualify for additional tax relief or freezes on certain assessments.
• Disability Exemptions: Individuals with qualifying permanent disabilities may be eligible for specific tax reductions.
• Veteran Exemptions: Certain disabled veterans or surviving spouses may qualify for exemptions depending on the level of service-connected disability.

Payment Schedule & Deadlines

Property taxes in Tulsa County are typically billed annually. While the exact date can vary, tax statements are generally mailed in the autumn. To avoid penalties, payments must be received by the Tulsa County Treasurer's office by the designated deadline, often November 30th.

Oklahoma law allows for certain installment options or payment plans in specific circumstances, but most homeowners pay in a single annual lump sum. It is critical to meet these deadlines; late payments result in the accrual of interest penalties and may eventually lead to a tax lien being placed on the property if the debt remains unpaid.

Appealing Your Assessment

If you believe your property has been overvalued by the County Assessor, you have the right to appeal. The appeals process generally begins with an informal review with the Assessor's office to discuss discrepancies in property data or market comparables.

If an agreement cannot be reached, you may file a formal appeal with the Board of Equalization (BOE). You will be required to provide evidence—such as a recent independent appraisal or a list of similar properties that sold for less—to support your claim for a lower valuation. Be mindful of strict filing deadlines to ensure your appeal is heard.
