Notice Regarding California Supplemental Property Taxes

When you buy real estate in California, the county assessor issues one or two Supplemental Property Tax Bills to account for the difference between the prior owner’s assessed value and your new purchase price for the remainder of the fiscal year.

Supplemental bills are mailed directly to you and are often not paid by your mortgage lender’s impound escrow account. Always verify escrow reserves with your loan officer.

Frequently Asked Questions: California Property Taxes & Mortgages

Everything you need to know about Proposition 13 caps, county bond rates, and mortgage qualification.

The California Homeowners Exemption reduces the taxable assessed value of your primary residence by $7,000. It does not subtract $7,000 directly from your taxes.

At typical California ad valorem tax rates of 1.10% to 1.25%, reducing your assessed value by $7,000 saves you roughly $77 to $88 per year in property taxes. You must occupy the property as your principal residence on January 1 to qualify.
