Rate Breakdown

Property taxes in Alpine County are calculated by multiplying the assessed value (minus exemptions) by the total local millage rate.

How Property Tax Works in Alpine County

Alpine County follows California’s statewide property‑tax system, which is based on the assessed value of real‑property and a set of local millage rates. The county assessor determines the “base year value” of each parcel on the date of purchase or when new construction is completed, whichever occurs later. This value is then adjusted annually for inflation by a maximum of 2 % under Proposition 13.

Once the assessed value is established, the tax bill is calculated by applying the combined millage rate. One mill represents $1 of tax per $1,000 of assessed value (0.001). Alpine County’s general‑purpose millage typically hovers around 6.5 mills, while school districts, special districts, and voter‑approved indebtedness add additional mills, bringing the total rate to roughly 10‑12 mills (about 1 % of assessed value). The exact rate can vary each fiscal year based on local ballot measures and debt repayments.

Available Exemptions

California law offers several exemptions that can reduce the taxable portion of your property’s assessed value. In Alpine County you may qualify for one or more of the following:

• Homeowners’ (Homestead) Exemption: Reduces the assessed value by $7,000 for owner‑occupied, single‑family residences.
• Senior Citizen Exemption: Residents age 65 or older may receive a reduction of $7,000 (or $14,000 if also disabled) from the assessed value, provided they meet income limits.
• Disabled Persons Exemption: Qualified persons with a documented disability can claim a $7,000 reduction, independent of age.
• Veteran Exemption: Disabled veterans (and surviving spouses) with a service‑connected disability may receive a $7,000 exemption, with larger reductions available for permanently and totally disabled veterans.

To claim these exemptions, file the appropriate claim form with the Alpine County Assessor’s Office before the annual assessment date (usually July 1). The assessor will verify eligibility and adjust your assessment for the following tax year.

Payment Schedule & Deadlines

Alpine County property taxes are due in two installments:

• First installment: November 1 – December 10 (late fees begin December 11).
• Second installment: February 1 – April 10 (late fees begin April 11).

Payments can be made online, by mail, or in person at the County Treasurer‑Tax Collector’s office. If you prefer, you may enroll in a pre‑authorized debit plan for automatic quarterly withdrawals.

Late payments are subject to a 10 % penalty plus a 1 % per month interest charge on the delinquent amount. Property may be placed under a tax lien after 90 days of non‑payment, and continued delinquency can lead to a tax‑sale auction. Conversely, if you qualify for the Property Tax Postponement Program (seniors, disabled, low‑income), you may defer payment of the principal balance while interest accrues.

Appealing Your Assessment

If you believe your property’s assessed value is inaccurate, you have the right to protest. Follow these steps:

• File a petition: Submit a written protest to the Alpine County Assessment Appeals Board (AAB) by the legal deadline—typically July 15 of the tax year.
• Gather evidence: Provide recent sales data for comparable properties, an independent appraisal, or evidence of physical defects that affect value.
• Attend a hearing: The AAB will schedule a public hearing where you can present your case. An oral argument is optional but can help clarify complex issues.
• Decision: The board issues a written decision within 30 days. If you disagree, you may appeal to the California State Board of Equalization, and ultimately to the Superior Court.

Preparing a well‑documented protest and meeting all filing deadlines greatly improve your chances of a successful reduction in taxable value.
