Step 1: Know the Base Tax Rate
In California, the standard property tax rate is:
1% of the assessed value of the property
This base rate is set by the state and applies to all counties.
Step 2: Understand Assessed Value vs. Market Value
The assessed value of your home may be different from its market value .
- Assessed value is determined by the county assessor
- It’s typically based on the purchase price
- Under Proposition 13 , the assessed value can only increase by up to 2% per year , regardless of market changes
Example: If you bought a home for $500,000, your initial assessed value is $500,000. Even if the home’s market value rises to $700,000, your assessed value increases gradually (by up to 2% annually).
Step 3: Add Local Assessments and Fees
In addition to the 1% base tax, you may also pay:
- Special assessments for local improvements (e.g., street lights, sewer lines)
- Mello-Roos taxes for infrastructure or community services in newer developments
- School district bonds or voter-approved levies
These additional charges vary by location and appear as line items on your tax bill.
Step 4: Use the Full Formula to Calculate Your Tax
Here’s the full formula:
Total Real Estate Tax = (Assessed Value × 1%) + Special Assessments + Other Fees
Example Calculation:
| Item | Amount |
|---|---|
| Assessed Value | $500,000 |
| Base Tax (1%) | $5,000 |
| Mello-Roos Assessment | $800 |
| School Bond Fee | $300 |
| Total Annual Property Tax | $6,100 |
Step 5: Check Your County Tax Collector’s Website
