How Property Tax Works

Johnson County, Kentucky operates under the state's property tax system to fund essential local services including schools, roads, public safety, and county government operations. Property taxes are based on assessed values determined by the Kentucky Department of Revenue's Office of Property Valuation, with assessment occurring annually as of January 1st. The county's effective tax rates typically range from approximately 0.8% to 1.2% of assessed value, depending on your specific location within the county.

Property tax rates vary significantly across Johnson County due to multiple special taxing districts, including school districts, fire districts, and other local service areas. Each property owner pays a combination of state, county, school, and applicable special district taxes based on their property's location. The total tax rate is expressed as dollars per $100 of assessed value, with the state base rate at $0.45 per $100 for most property types.

Supplemental Tax Bills

Supplemental taxes in Johnson County occur when there are significant changes to property ownership, substantial improvements, or new construction that affect the assessed value during the tax year. These taxes are calculated on a prorated basis from the date of the change through the end of the tax year. Common triggers include property transfers, completion of new construction, additions to existing structures, or corrections to assessment errors discovered mid-year.

For example, if you complete a $50,000 home addition in July and your local tax rate is $1.00 per $100 of assessed value, you would owe a supplemental tax of approximately $250 (($50,000 ÷ 100) × $1.00 × 0.5 years remaining). The supplemental tax bill is typically issued within 30-60 days of the assessment change and has its own due date separate from regular property tax bills.

Escrow & Property Taxes

Most mortgage lenders in Johnson 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 each month along with your mortgage payment, then pays the county directly when taxes are due. Lenders typically maintain a cushion of 2-6 months of tax payments in the escrow account to cover potential increases or timing differences.

Property tax bills in Johnson County are typically due by November 15th each year, with early payment discounts available if paid by November 1st (2% discount). Your lender will receive the tax bill and make payment from your escrow account. It's important to verify that payments are made timely, as you remain ultimately responsible for the taxes even when using escrow. You can monitor payments through the Johnson County Clerk's website and should review your annual escrow analysis statement to ensure adequate funding.
