Tax Rate Details
Understanding Millage Rates in St. Clair County
In Alabama, property taxes are expressed as a millage rate (also called a mill rate). One mill equals $1 of tax for every $1,000 of assessed property value. Your total property tax bill is determined by adding together the millage rates set by the county, city or municipality, school district, and any special districts.
In Alabama, residential property is assessed at 10% of appraised market value. This means a home appraised at $200,000 has an assessed value of $20,000, and the millage rate is applied to that assessed value — resulting in some of the lowest effective property tax bills in the nation.
St. Clair County has an effective property tax rate of 0.30%, resulting in a median annual tax bill of $666. Use the calculator above to estimate your property tax based on St. Clair County's current rate, or contact the St. Clair County tax assessor's office for the exact millage rate breakdown for your property.
