How Property Tax Works

Beckham County, Oklahoma operates under a property tax system that funds essential local services including schools, county operations, municipal services, and various special districts. Property taxes are levied annually on October 1st based on the assessed value as of January 1st of the same year, with taxes becoming due on November 1st following the levy date.

The effective tax rate in Beckham County varies significantly by location within the county due to multiple overlapping taxing jurisdictions and special districts. Based on available data, property owners can expect rates that align with Oklahoma's general range, though specific millage rates depend on your property's location within various school districts, municipal boundaries, and special taxing districts. Property is assessed at fair cash value, and Oklahoma law requires county-wide reappraisal at least once every four years to ensure current market valuations.

Section 2

What Makes Up Your Tax Bill

Due to the complex structure of overlapping taxing jurisdictions in Beckham County, property tax rates vary by specific location. The total millage rate depends on which combination of taxing districts your property falls within:

Section 4

Supplemental Tax Bills

Supplemental taxes in Beckham County are additional property tax assessments that occur when there are changes to property ownership, value, or use during the tax year. The most common triggers include new construction completion, property improvements that increase value, or changes in property classification.

When supplemental taxes are levied, they are calculated based on the difference between the old assessed value and the new assessed value, prorated for the remaining months in the tax year. For example, if a $50,000 home addition is completed in July, you would owe supplemental taxes on that additional assessed value from July through the end of the tax year. These supplemental bills are issued separately from your annual property tax bill and have their own due dates.

Escrow & Property Taxes

Most mortgage lenders require property tax escrow accounts for Beckham County properties. Your lender collects 1/12th of your estimated annual property tax bill with each monthly mortgage payment, depositing these funds into an escrow account. The lender then pays your property taxes directly to Beckham County when they become due on November 1st.

Since Oklahoma allows property taxes to be paid in two equal installments, some lenders may choose to pay the first half by the November 1st deadline and the second half by the spring deadline. Your lender will provide an annual escrow analysis showing how much was collected, paid out, and any adjustments needed for the coming year. If your property taxes increase due to reassessment or rate changes, your monthly escrow payment will be adjusted accordingly.
