How Property Tax Works

Shelby County, Alabama operates under a property tax system that funds essential county services including schools, public safety, infrastructure, and local government operations. The county follows Alabama's property tax structure where properties are assessed annually and taxes are levied based on the assessed value multiplied by the applicable tax rate.

For the 2025 tax year, Shelby County has a base property tax rate of 2.69% that applies to all property classifications within the county. However, your actual tax rate may vary depending on your specific location within Shelby County due to additional special taxing districts, municipal taxes, and school district levies. Properties are assessed at their current market value, and taxes become a lien on October 1st each year, with bills typically mailed in November and due the following October 1st.

Section 4

Supplemental Tax Bills

Supplemental taxes in Shelby County are additional property tax assessments that occur when there are changes to a property's ownership, value, or use outside the regular annual assessment cycle. These typically arise from new construction, major improvements, or changes in property classification that increase the assessed value.

When supplemental taxes are levied, they are calculated based on the difference between the old and new assessed values, multiplied by the applicable tax rate, and prorated for the remaining portion of the tax year. For example, if you complete a $50,000 home addition in March and your tax rate is 3.5%, you would owe supplemental taxes on that $50,000 increase for the remaining 9 months of the tax year, calculated as ($50,000 × 3.5% × 9/12 = $1,312.50).

Escrow & Property Taxes

Most mortgage lenders in Shelby County require borrowers to maintain an escrow account for property tax payments. Your lender collects monthly escrow payments along with your mortgage payment, typically 1/12th of your annual property tax bill. The lender then pays your property taxes directly to Shelby County when they become due in October.

Lenders are required to conduct annual escrow analyses to ensure adequate funds are collected. If property taxes increase, your monthly escrow payment may be adjusted upward, and you may need to pay any shortage over 12 months or as a lump sum. Property owners should verify that their lender pays taxes on time, as the property owner remains ultimately responsible for timely payment even when using escrow services. You can verify payments through the Shelby County Revenue Commissioner's office or online payment portal.
