The Alabama property tax appeal deadline is 30 days from the date your county mails your Notice of Valuation — making it one of the shorter appeal windows in any state TaxAppeal serves. Unlike Florida's fixed September deadline or Arkansas's statewide August 17 date, Alabama's deadline is specific to each property and each county's mailing schedule. Most Alabama counties mail notices between April and August. This guide tells you exactly what to watch for and what to do when your notice arrives.
How the Alabama 30-Day Deadline Works
Your 30-day clock starts from the mailing date printed on your Notice of Valuation — not the date you received it. If your notice was mailed on May 1, your deadline is May 31 regardless of when it arrived in your mailbox. Alabama uses a postmark deadline, meaning your appeal only needs to be postmarked by the deadline date — not physically received. TaxAppeal files 7–10 days early via certified mail to ensure documented proof of timely filing.
- ✓Clock starts: Mailing date on notice (not receipt date)
- ✓Window length: 30 calendar days
- ✓Deadline type: Postmark — postmark by deadline is sufficient
- ✓Typical notice window: April through August depending on county
- ✓File early: TaxAppeal files 7–10 days before the deadline
Madison County Exception: Newspaper Deadline
Madison County (Huntsville) does not mail individual notices. Instead, new values are published in a local newspaper, and the 30-day appeal window runs from the date of the second newspaper advertisement. Madison County homeowners must actively monitor local newspapers each spring — typically March or April — to catch the publication date.
- ✓Watch for: Public Notice of Values in Huntsville-area newspapers
- ✓Deadline trigger: Date of second newspaper advertisement
- ✓Typical publication: March or April
- ✓Missing the newspaper notice can mean missing the deadline
What Happens If You Miss the Deadline
If the 30-day window closes without a filed appeal, your Notice of Valuation becomes final for the current tax year. Options are very limited — contact your county assessor to ask about any administrative correction procedures for data errors. Your next opportunity is the following year's assessment cycle. Set an April 1 reminder each year to watch for your Notice of Valuation.
