How Jefferson County property taxes are determined

Calculating property taxes starts with the Jefferson County Assessor’s office, which determines the fair market value of your property. Based on the state of the market, the assessor will determine how much your property would sell for if it were put up for sale.
Then, the assessor multiplies the fair market value with the assessment ratio set by the state legislature. (The Jefferson County assessment ratio is 19% for residential properties, 12% for agricultural properties, and 32% for commercial properties.) This yields your “assessed value.”
Finally, the assessed value is multiplied by the tax rate to determine how much you’ll pay in taxes that year.
Jefferson County has over 60 approved tax levies, but which ones apply to your property depends on your jurisdiction. 
If your property is your primary residence, then you might qualify for a homestead exemption, which can lower the assessed value of your property and thus lower your taxes owed.
Key Takeaway The amount you owe in property taxes is determined by multiplying your property’s fair market value by your assessment ratio, then by your local tax rate.
