How to read this table
What each column means and where the number or rating comes from.
State Population
The state and its latest U.S. Census population estimate, shown with its share of the total US population as a rough measure of market size.
2026 appeal deadline Quarter
The date, or recurring rule, by which a homeowner must file a residential appeal for the 2026 cycle, plus the calendar quarter it falls in (Q1 = Jan–Mar, Q2 = Apr–Jun, Q3 = Jul–Sep, Q4 = Oct–Dec). States whose deadlines vary by county show a range, e.g. Q2–Q3.
Type
Fixed = same calendar date every year. Relative = a set number of days from when your notice is mailed. Formula = a recurring rule (e.g. "first Monday in August"). Variable = differs by county within the state.
Filing fee
The typical cost to file a first-level residential appeal, with the county-by-county breakdown beneath it (how many counties charge each amount). Most states are free in every county.
Appeal success
How often filed appeals win a reduction, in three bands: High (≥50% — wins likely), Medium (33–49% — winnable case-by-case), Low (under 33% — reductions structurally rare). Texas, Florida, Illinois, New York and Washington are based on observed or published rates; all others are research estimates.
Outlook
The reason behind the success rating: the structural factor (assessment caps, ratios, reappraisal cycles, disclosure rules) that drives wins or limits them in that state.
