Assessed Value

The value assigned to a property by a government assessor for the purpose of calculating property taxes, which may differ from market value.

How It Works

In many states, assessed value is a fraction of market value (e.g., 10% in Louisiana, 100% in California). Assessment ratios and revaluation schedules vary by state and even by county. Some states cap annual assessment increases (like California's Prop 13 at 2% per year), which can cause assessed values to diverge significantly from market values over time. Assessment accuracy is a major equity issue — systematic under- or over-assessment affects which taxpayers bear more or less of the tax burden.
