How Property Tax Works

Sequoyah County, Oklahoma operates under the state's property tax system to fund essential local services including schools, roads, emergency services, and county operations. Property taxes are based on assessed values determined by the County Assessor and calculated using millage rates set by various taxing authorities within the county.

The effective property tax rate in Sequoyah County is approximately 1.417% as of 2025, though actual rates vary significantly by location within the county due to different combinations of special taxing districts, school districts, and municipal boundaries. Property owners should expect their specific tax rate to differ based on their exact location and the overlay of local taxing jurisdictions that serve their property.

Oklahoma uses an ad valorem system where property is assessed at its fair cash value, and taxes are calculated by applying the combined millage rates of all applicable taxing districts. Most tax credits and exemptions require annual application and are not automatically applied to your tax bill.

When Are Property Taxes Due?

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 Oklahoma are typically triggered by changes in property ownership, new construction, or improvements that increase assessed value during the tax year. When property changes hands or improvements are completed, the County Assessor may issue a supplemental assessment to capture the increased tax liability for the remaining portion of the tax year.

Supplemental taxes are calculated by determining the difference between the new assessed value and the previous assessed value, then applying the applicable tax rate for the remaining months in the tax year. For example, if a $100,000 home improvement is completed in July, and the property is in an area with a 1.417% effective tax rate, the supplemental tax would be approximately $708.50 for the remaining portion of the year (assuming a 6-month proration).

Property owners typically receive supplemental tax bills separately from their regular tax bills, and these must be paid according to the due dates specified on the supplemental bill.

Escrow & Property Taxes

Most mortgage lenders in Sequoyah County require property tax escrow accounts for borrowers with less than 20% down payment. Lenders collect monthly property tax payments along with principal, interest, and insurance, then pay the county directly when taxes are due.

Property taxes in Sequoyah County are typically paid in two installments: the first half is due by March 15, and the second half is due by September 15. Lenders usually pay each installment shortly before the due date to avoid penalties. Property owners should receive annual escrow statements showing tax payments made on their behalf.

Homeowners should verify that their lender is paying the correct amount by reviewing their tax bills and escrow statements. If you believe your escrow payment is incorrect, contact your lender with a copy of your current property tax bill to request an escrow analysis and adjustment.
