October Property Tax Deadlines by State: What's Due This Month
TL;DR
October brings the New Jersey Tax Court filing deadline (October 1), Alabama assessment notices and appeals, Oregon assessment notices, and several major payment deadlines. Florida VAB hearings begin this month. California's appeal window remains open through November 30. Payment deadlines hit in Alabama (October 1), Tennessee (October 1), Minnesota (October 15), South Dakota (October 31), and Washington (October 31). If you are in New Jersey and missed the April 1 county deadline, October 1 is your last chance.
October Appeal Deadlines
| State | Deadline | Where to File |
|---|---|---|
| New Jersey | October 1 (Tax Court) | New Jersey Tax Court |
| Alabama | 30 days after notice (notices arrive October-November) | County Board of Equalization |
| Oregon | December 31 (notices arrive in October) | Board of Property Tax Appeals |
| California | Window open through November 30 | County Assessment Appeals Board |
Key October Deadlines Explained
New Jersey Tax Court - October 1
If you missed New Jersey's April 1 county tax board deadline, you have a second chance: the New Jersey Tax Court accepts filings through October 1. This is particularly valuable for homeowners with higher-value properties, as the Tax Court handles cases with more formal procedures and can provide more substantial relief.
Note: the Tax Court filing fee is $50, and the process is more formal than the county tax board. But for New Jersey homeowners paying some of the highest property taxes in the nation, the potential savings far outweigh the fee.
Alabama - 30 Days After Notice
Alabama assessment notices typically arrive in October or November. You have 30 days from the notice date to file an appeal with the county Board of Equalization. Alabama assesses at different ratios depending on property type (10% for Class III owner-occupied, 20% for Class II non-owner-occupied).
Oregon - Notices Arrive, Appeals Due December 31
Oregon assessment notices arrive in October, and appeals are due to the Board of Property Tax Appeals by December 31. This gives you about two months to review your notice, gather evidence, and file. Oregon uses a unique system where both "real market value" and "assessed value" appear on your notice. Due to Measure 5 and Measure 50 limitations, your assessed value may be significantly lower than market value.
You should appeal if the real market value on your notice exceeds what your home would actually sell for. Even if it does not affect your current taxes (because the assessed value is already lower), correcting the real market value can prevent future tax increases.
