How Property Tax Works

Garvin County, Oklahoma operates under a property tax system that funds essential local services including schools, county operations, fire protection, and various special districts. Property taxes are collected by the County Treasurer and distributed to the appropriate taxing entities based on where your property is located within the county. The county serves approximately 28,400 residents across various municipalities and rural areas.

Property tax rates in Garvin County vary significantly depending on your specific location due to the overlay of different special taxing districts such as school districts, fire districts, and municipal services. While Oklahoma maintains a baseline assessment approach, your actual tax burden depends on which combination of local taxing authorities serve your property. The County Assessor determines assessed values, while individual taxing entities set their levy rates annually to fund their operations.

Supplemental Tax Bills

Supplemental taxes in Garvin County are additional tax assessments that occur when there are changes to property ownership, improvements, or corrections to the original assessment during the tax year. The County Assessor is required to maintain permanent records of all taxable real property and may issue supplemental assessments when property values change due to new construction, major improvements, or assessment corrections.

When a supplemental assessment is issued, it covers the period from when the change occurred through the end of the current tax year. For example, if you complete a home addition in March, you would receive a supplemental tax bill covering the increased assessment from March through the following February (the end of the tax year). The supplemental amount is calculated by applying the current tax rate to the difference between the old and new assessed values, prorated for the remaining months in the tax year.

Escrow & Property Taxes

Most mortgage lenders in Garvin County require borrowers to maintain an escrow account for property tax payments. Your lender collects approximately 1/12 of your estimated annual property tax bill with each monthly mortgage payment. The lender then pays your property taxes directly to the Garvin County Treasurer when the installments are due.

Property taxes in Garvin County are typically paid in two installments: the first installment is due by September 15, and the second installment is due by December 15. Your lender will receive the tax bills and make these payments on your behalf. Each year, your lender conducts an escrow analysis to ensure adequate funds are being collected, and may adjust your monthly payment up or down based on actual tax bills and account balances. You should receive an annual escrow statement showing all deposits and payments made from your account.
