Property Taxes in Mobile
Mobile property taxes are genuinely, reliably low by national standards: Alabama assesses residential (Class III) property at just 10% of market value, Mobile's median effective property tax rate is cited at 0.61% (Mobile County's broader average runs lower at 0.47%), and a state homestead exemption removes the first $4,000 of assessed value from non-school property tax -- Alabama is commonly cited as having the 2nd-lowest state property tax rate in the country.

Learn moreA Genuinely Low Assessment Ratio Drives Low Bills
Alabama assesses Class III residential property at just 10% of its market value -- meaning only a tenth of a home's appraised value is subject to the county/city millage rate in the first place. This low assessment ratio, combined with constitutional rate caps and wide exemptions, is the primary mechanism behind Alabama's genuinely low property tax bills, not a single low millage rate alone.
Mobile's Effective Rate: Two Real, Slightly Different Figures
Mobile's median effective property tax rate is cited at 0.61% by one source (Ownwell), above the Alabama statewide median of 0.47% but still well below the 1.02% national median. A separately cited Mobile County-wide average effective rate of 0.47% runs lower than the city-specific figure -- both are disclosed here rather than reconciled to one number, since city and countywide figures commonly diverge due to differing local millage overlaps.
The State Homestead Exemption and Senior Exemption
Alabama's homestead exemption removes the first $4,000 of a home's assessed value (equivalent to $40,000 of appraised value, at the 10% assessment ratio) from all property tax except countywide and school-district school taxes. Homeowners 65 or older with an annual income under $12,000 may qualify for a full property tax exemption on their primary residence under Alabama Code Section 40-9-21 -- confirm current eligibility and application procedures directly with the Mobile County Revenue Commissioner's office.
Alabama Ranks Among the Nation's Lowest for Property Tax
Multiple 2026 sources cite Alabama as having the 2nd-lowest effective property tax rate in the country (Hawaii is typically cited as lowest by effective rate), with one source specifically citing Alabama as having the lowest actual median property tax bill of any state at $788/year -- a genuinely low, real, and nationally distinctive figure, not a marginal discount.
Confirm ZIP-Code-Level Variance for a Specific Address
Even within Mobile, tax bills vary by ZIP code depending on differing school district levies and local assessment districts -- one source cited a range from roughly $242 in one Mobile ZIP code to $1,575 in another. Confirm the actual current tax bill for a specific address directly with the Mobile County Revenue Commissioner rather than relying on the citywide median.
