How Are Property Taxes Calculated in San Diego County?
The assessed value of a home is the key determinant of property taxes. In San Diego County, this is calculated as follows:
1. Initial Property Assessment:
- When a home is purchased, the assessed value equals the purchase price.
- If the home is not recently purchased, its assessed value is based on the previous year’s value plus a maximum 2% increase (per Proposition 13).
2. Applying the Base Tax Rate:
- Base rate: 1% of the assessed value.
3. Adding Local Assessments:
- Voter-approved school bonds, infrastructure projects, and municipal assessments can add 0.1% to 0.5%.
Example Calculation for a $750,000 Home in Chula Vista (2025):
| Component | Calculation | Amount |
|---|---|---|
| Base Tax (1%) | $750,000 × 1% | $7,500 |
| Local Bonds (0.15%) | $750,000 × 0.15% | $1,125 |
| Special Assessments | Fixed fee estimate | $200 |
| Total Tax Due | $7,500 + $1,125 + $200 | $8,825/year |
