How Property Tax Works

Mayes County, Oklahoma operates on a property tax system that funds essential local services including schools, law enforcement, fire protection, roads, and county operations. Property taxes are levied annually on October 1st based on the assessed value of real estate and personal property within the county. The county follows Oklahoma's statewide assessment practices, with most residential property assessed at approximately 11% of fair market value.

Property tax rates in Mayes County vary significantly by location due to multiple overlapping taxing jurisdictions including school districts, municipalities, fire districts, and other special assessment areas. While Oklahoma's base property tax environment averages around 1% of market value statewide, your actual effective rate in Mayes County will depend on which specific taxing districts serve your property. The county assessor determines assessed values, while individual taxing entities set their mill levy rates to generate required revenue for local services.

Supplemental Tax Bills

Supplemental taxes in Mayes County are additional property tax assessments that occur when property changes ownership, undergoes new construction, or experiences significant improvements after the annual assessment date of January 1st. These supplemental bills ensure that property taxes reflect current ownership and property conditions throughout the tax year.

Common triggers for supplemental taxes include purchasing a home, completing new construction, adding significant improvements like additions or pools, or correcting assessment errors. The supplemental tax is calculated by determining the difference between the old assessed value and new assessed value, then applying the current tax rate to that difference for the remaining portion of the tax year. For example, if you purchase a $400,000 home in March that was previously assessed at $300,000, you would receive a supplemental bill for the increased assessed value (approximately $11,000 difference × 11% assessment ratio × applicable mill rate) prorated from March through the end of the tax year.

Escrow & Property Taxes

Most mortgage lenders in Mayes County require property tax escrow accounts to ensure timely payment of property taxes. Your lender collects 1/12th of your estimated annual property tax bill with each monthly mortgage payment, holding these funds in a separate escrow account. Since Mayes County property taxes are due November 1st annually, your lender will typically pay the full tax bill directly to the county treasurer around the due date.

Lenders must provide an annual escrow analysis showing the account activity and any adjustments needed for the coming year. If your property taxes increase due to reassessment or rising mill rates, your monthly escrow payment will be adjusted accordingly. You can verify that your taxes were paid correctly by checking with the Mayes County Treasurer's office or accessing online payment records. If you pay your mortgage off or refinance, ensure the escrow account is properly transferred or closed, and be prepared to make property tax payments directly to the county going forward.
