Estimate Your Annual Property Tax

Calculate how much you can expect to pay in property taxes based on your home's assessed value and local tax rates. See the breakdown for your Southern California property.

How Property Taxes Are Calculated

Property taxes in California are governed primarily by Proposition 13, which caps the base-year assessed value at the purchase price and limits annual increases to no more than 2% per year, regardless of actual market appreciation. When you buy a property, the county assessor establishes a new base-year value equal to the sale price. Your annual tax bill is then calculated by multiplying that assessed value by the local tax rate, which is approximately 1% of assessed value plus any voter-approved bonded indebtedness and special assessments.

This means that two identical homes on the same street can have very different tax bills if they were purchased in different years. A home bought in 1990 may have an assessed value far below current market value, resulting in a much lower tax bill than a recently purchased neighbour. The effective tax rate in most San Diego County areas ranges from about 1.0% to 1.25% when including all supplemental assessments and Mello-Roos district fees. Use this calculator to estimate your tax based on the actual purchase price or current assessed value.

Keep in mind that supplemental tax bills may apply in the first year after purchase, and certain exemptions (such as the homeowner's exemption of $7,000 off assessed value) can slightly reduce your bill. Always check your county assessor's website for the most precise figure.

Frequently Asked Questions

How are property taxes calculated?
Property taxes are calculated by multiplying your property's assessed value by the local tax rate (mill rate). The assessed value is determined by your provincial or county assessment authority, and the tax rate is set annually by your municipality during its budget process. Your total bill typically includes both a municipal portion and an education portion.
What is a mill rate?
A mill rate is the amount of tax per dollar of assessed property value. One mill equals $1 of tax per $1,000 of assessed value. For example, a mill rate of 12.5 on a property assessed at $400,000 produces an annual tax bill of $5,000. Mill rates vary widely between municipalities and are adjusted each year to meet budgetary needs.
How often are properties reassessed?
Assessment frequency varies by jurisdiction. In British Columbia, properties are reassessed every year by BC Assessment. In Ontario, MPAC reassesses on a four-year cycle (though values may be phased in). In California, assessed value is typically set at purchase price and increases by no more than 2% per year under Proposition 13, with full reassessment only upon sale or new construction.
Do property taxes change when I buy a home?
In most Canadian provinces, property taxes are based on assessed value regardless of the sale price, so they may not change immediately. However, if the assessment authority updates the property's value to reflect the purchase price, your bill could change at the next assessment cycle. In California, property taxes are explicitly reset to the purchase price upon sale.
What is the education tax portion of my property tax bill?
Most Canadian property tax bills include an education levy that funds the public school system. This typically represents 35-45% of the total bill, though the exact split varies by municipality. The education rate is usually set by the provincial government, while the municipal rate is set locally. In the US, school district taxes are a separate line item and vary significantly by district.
