The budget is an annual financial plan for Johnson County Government. It specifies the level of county services to be provided in the coming year and the resources, including personnel positions, capital expenditures, and operating expenses needed to provide these services. It reflects the policies and priorities set by the Board of County Commissioners.

Johnson County’s 2025 tax levy rate (in mills) is 24.110. Johnson County has three taxing districts: 

1. County 17.276
2. Library 3.812
3. Park and Recreation 3.018

One mill is equal to $1.00 of property taxes per $1,000 of taxable value.

There is no difference. They are different names for the same tax.

It is the county's annual financial plan for recurring expenses, such as employee salaries and benefits, utilities, supplies and equipment, and other costs required to provide public services and programs.

Certain revenue in the county budget is dedicated by either state law or county policy to specific programs. These "dedicated funds" cannot be used for any other purpose. For example, wastewater capital and user charges can only be used to help pay for wastewater projects and operations, fees and charges for library programs and services can only be used to support the library.

The Capital Improvement Program is the county's annual financial plan for the construction of physical assets, such as construction of new buildings, improvements to existing county facilities, constructing and improving roadways, and funding of wastewater and stormwater projects.

The general fund pays for the day-to-day operations of critical services the public expects but which are not supported by any other revenues.

A fiscal year is a 12-month operating cycle that comprises a budget and financial reporting period. Fiscal years are different for governments.

The fiscal year for local governments, including Johnson County and its cities, begins on Jan. 1 and ends on Dec. 31 in the same calendar year.

The fiscal year for the State of Kansas begins on July 1 and ends on the following June 30.

The fiscal year for the federal government starts on Oct. 1 and ends on the following Sept. 30.

The Johnson County Appraiser's Office, located in the Sunset Drive Office Building, 11811 South Sunset Drive, Olathe, annually assesses the taxable value of all property in Johnson County.

The Board of County Commissioners has no control over the taxable value of property; it only has control over the annual property tax rate that is levied.

Your property tax dollars are used by city and county governments to provide funding for roads, parks, fire protection, law enforcement, public schools and many other local services.

By state law, the county appraiser is responsible for listing and valuing property in a uniform and equal manner. The appraiser estimates only the value of your property. The amount of taxes you pay depends on the budgets set in August by city and county governments.

The average county's average sales tax rate is 9.325%. This includes the statewide sales tax.
