Property Valuation Information

| Value Type | Definition | Role in Taxation |
|---|---|---|
| Assessed Value | Appraiser’s opinion of worth | Baseline figure |
| Market Value | Likely sale price | Drives assessed value |
| Taxable Value | Value after exemptions | Multiplied by tax rate |
Assessed Value
This figure represents the appraiser’s opinion of market value. The Ada county tax assessor sets this number based on mass appraisal. It serves as the baseline for taxation. Idaho law requires assessed values to match current market values.
Market Value
