How Property Tax Works

Tulsa County, Oklahoma operates a property tax system that serves as a primary funding source for essential local services including schools, public safety, infrastructure maintenance, and county operations. Property owners in Tulsa County are subject to an effective tax rate of approximately 0.367% (or 3.67 mills) based on the assessed value of their property. This rate applies countywide, including incorporated cities like Tulsa, Broken Arrow, and other municipalities within the county boundaries.

The Oklahoma property tax system assesses real property at its fair cash value, with taxes calculated on this assessed amount after applicable exemptions. Tulsa County benefits from Oklahoma's generous homestead exemption, which provides unlimited value protection for qualifying owner-occupied residences, making it one of the most homeowner-friendly states in the nation. Property taxes are collected in two installments annually, with proceeds distributed to fund county government, school districts, municipalities, and various special districts throughout Tulsa County.

Supplemental Tax Bills

Supplemental property taxes in Tulsa County are additional tax assessments that occur when there are changes to a property's value or ownership outside the normal assessment cycle. The primary triggers for supplemental taxes include new construction completion, major property improvements that increase assessed value, property ownership transfers, or corrections to previous assessments. When these events occur, the county assessor determines the additional taxable value and applies the current tax rate to calculate the supplemental amount.

For example, if you complete a $50,000 home addition in July, the assessor will calculate supplemental taxes on that improvement for the remaining months of the tax year. The $50,000 improvement would generate approximately $183.50 in supplemental taxes ($50,000 × 0.00367 rate) prorated for the partial year. Supplemental tax bills are issued separately from regular property tax bills and typically have their own payment deadlines, usually 30 days from the bill date.

Example Calculation

$300,000 Property

  • Assessed Value: $300,000
  • Less Homestead Exemption: $300,000 (unlimited for owner-occupied)
  • Net Taxable Value: $0
  • Annual Tax: $0 × 0.00367 = $0
  • Monthly Escrow: $0

$600,000 Property

  • Assessed Value: $600,000
  • Less Homestead Exemption: $600,000 (unlimited for owner-occupied)
  • Net Taxable Value: $0
  • Annual Tax: $0 × 0.00367 = $0
  • Monthly Escrow: $0

$1,000,000 Property

  • Assessed Value: $1,000,000
  • Less Homestead Exemption: $1,000,000 (unlimited for owner-occupied)
  • Net Taxable Value: $0
  • Annual Tax: $0 × 0.00367 = $0
  • Monthly Escrow: $0

Note: Oklahoma's unlimited homestead exemption eliminates property taxes for most owner-occupied residences. Non-homestead properties (rental, commercial, vacant land) pay the full rate.

Escrow & Property Taxes

Most mortgage lenders in Tulsa County require borrowers to maintain an escrow account for property tax payments, collecting monthly deposits along with principal and interest payments. Lenders typically collect 1/12th of the annual property tax amount each month, then remit payments directly to the Tulsa County Treasurer on behalf of homeowners. Since Tulsa County property taxes are due in two installments (first half by April 15, second half by October 15), lenders usually make payments during these collection periods.

Property owners should verify their escrow payments annually by reviewing their mortgage statements against actual tax bills. If you pay taxes directly or want to verify escrow payments made by your lender, visit the Tulsa County Treasurer's website at https://www.treasurer.tulsacounty.org/ to check payment status and access current tax information. The site provides online payment options, bill lookup services, and downloadable tax records for your property.
