About Property Taxes in Oklahoma
Oklahoma property taxes are administered at the county level. Residential property is assessed at 11% of fair cash value, agricultural at 11%, and commercial at 11% as well (though rates vary by use). Oklahoma's assessment ratios and mill rates produce among the lower effective property tax rates in the country. Oklahoma also has a distinctive feature: the assessed value of owner-occupied primary residences cannot increase by more than 3% per year (the "assessment limitation"), regardless of market value increases. This provides strong protection against rapid tax increases for homeowners.
Payment & Assessment
Oklahoma property taxes are due December 31 and may be paid in two equal installments: First half: Due December 31 Second half: Due March 31 of the following year If the total tax is less than $100, it must be paid in full by December 31. A penalty of 1.5% per month applies to late payments. Most counties offer online payment. Contact your county treasurer for payment options.

About Greer County
Greer County is a county located along the southwest border of the U.S. state of Oklahoma. As of the 2020 census, the population was 5,491. Its county seat is Mangum. From 1860 to 1896, the state of Texas claimed an area known as Greer County, Texas, which included present-day Greer County along with neighboring areas. In 1896 it was designated as a county in Oklahoma Territory under a ruling by the US Supreme Court. The rural Greer County is home to Quartz Mountain State Park, near the community of Lone Wolf, Oklahoma. It is also home to the Oklahoma State Reformatory, located in Granite. Its population has declined since 1930 due to changes in agriculture and migration to cities for work.
