How Property Tax Works

Bibb County, Alabama operates on a property tax system that serves as a primary funding source for essential local services including public schools, county government operations, road maintenance, and emergency services. Property taxes in Bibb County are assessed annually based on the fair market value of real estate and personal property, with the state's base assessment rate of approximately 1% of market value serving as the foundation for tax calculations.

The effective property tax rate in Bibb County varies significantly depending on your specific location within the county due to different special taxing districts, school districts, and municipal boundaries. Property owners can expect rates to range from the base county levy to higher rates in areas with additional special assessments for services like fire protection districts, school bonds, or infrastructure improvements. The 2025 property tax rates have not yet been finalized and will be determined by the Bibb County Board of Revenue, so property owners should monitor local government announcements for the official rate determination.

Supplemental Tax Bills

Supplemental taxes in Bibb County are additional property tax assessments that occur when there are changes to property ownership, value, or use during the tax year. The most common triggers include new construction completion, property sales that trigger reassessment, major improvements or additions, and changes in property use classification.

When a supplemental tax is issued, it represents the difference between the original tax assessment and the new assessment, prorated for the portion of the tax year remaining. For example, if you complete a $50,000 home addition in March and it increases your assessed value by $50,000, you would owe additional tax on that increased value from March through the end of the tax year. The supplemental tax bill is typically issued within 60-90 days of the triggering event and has its own due date separate from the regular October 1st property tax due date.

Escrow & Property Taxes

Most mortgage lenders in Bibb County require property tax escrow accounts for borrowers with less than 20% equity. Your lender collects a portion of your estimated annual property tax bill each month along with your mortgage payment, depositing these funds into an escrow account. The lender then pays your property taxes directly to Bibb County when they become due on October 1st each year.

Lenders typically review escrow accounts annually and may adjust your monthly payment based on actual tax bills and account balances. If your property taxes increase due to reassessment or rate changes, your monthly escrow payment will likely increase at your next annual review. Property owners should verify that their lender has paid taxes on time, as you remain ultimately responsible for ensuring payment even when using escrow. You can verify payment status through the Bibb County Revenue Commissioner's office or online payment portal.
