How Assessment Works in Alabama
Alabama uses a classification system where residential property (Class III) is assessed at 10% of fair market value. Utilities and commercial property are assessed at higher rates. Your tax bill is based on 10% of what the county determines your home is worth.
Risk of Increase
In Alabama, filing a appeal can result in your assessed value being increased. This is uncommon when you have strong evidence of over-assessment, but you should be aware of this possibility. ProtestMax only recommends filing when our analysis shows a clear case for reduction.

FAQ
Alabama Property Tax Appeal Questions
How does the 10% assessment ratio work in Alabama?
If your home's fair market value is $200,000, your assessed value should be $20,000 (10%). Your tax bill is calculated on $20,000, not the full market value. If the county overvalues your home, you pay taxes on a higher assessed amount.
Can my Alabama assessment increase on appeal?
Yes. The Board of Equalization has the authority to adjust your assessment in either direction. However, increases during appeals are uncommon when you present strong evidence of over-assessment.
When is the deadline to appeal in Alabama?
Deadlines vary by county. Most counties require appeals to be filed within a specific window after assessment notices are mailed. Contact your county tax assessor's office for your specific deadline.
