Taxation and Finance Alabama 3 Minutes Read · published February 20, 2026 Flag of Alabama

In Mobile, Alabama, homeowners should understand how property valuations affect annual taxes, exemptions, and appeals. Valuations used for tax bills are administered by county and state authorities working with local records; Mobile residents commonly interact with the Mobile County Revenue Commissioner for assessments and with state guidance for valuation procedures.[1] This guide explains how values are set, how to check your assessment, the enforcement and penalties framework, and exact next steps to appeal or request a review.[2]

How valuations are determined

Property valuation for taxation typically reflects market value as of the assessment date and uses sales comparisons, cost, and income approaches where applicable. Assessors in Mobile County review sales data, building permits, and property records to set assessed value. Adjustments can occur after reappraisals, building permits, or appeals.

  • Assessment basis: market sales, cost, and income approaches where relevant.
  • Documentation considered: recent sales, permits, appraisal reports, and inspection notes.
  • Frequency: periodic reappraisals and annual tax roll updates.
Check your tax bill and the county assessment record early each year.

When valuations change and what to review

Typical triggers for a changed valuation include nearby sales that affect market value, new construction, demolition, or recorded building permits. Homeowners should review the property description, square footage, and recent sale comparables. If you find errors, begin by contacting the Mobile County Revenue Commissioner records division to request information and corrections.
