San Francisco Property Tax Calculator 2026 (Official Rate & Estimate)

How it works

San Francisco secured property tax is calculated by applying the official secured property tax rate to the assessed value of the property. The San Francisco Treasurer & Tax Collector publishes the secured property tax rate and issues secured property tax bills. The San Francisco Office of the Assessor-Recorder determines assessed values for real property. Under California Proposition 13, the base property tax rate is 1% of assessed value. The total secured rate can be higher because voter-approved bond debt and other local charges may be included. Assessed value is not necessarily the same as market value. In most cases, assessed value increases are limited to no more than 2% per year unless a reassessment event occurs, such as a sale, change in ownership, or new construction. This calculator multiplies the assessed value by the official secured property tax rate to estimate annual secured property tax.

Examples

Example 1: Using the official secured property tax rate of 1.18268325%, an assessed value of $500,000 results in an estimated annual secured property tax of approximately $5,913. Example 2: An assessed value of $800,000 results in an estimated annual secured property tax of approximately $9,461. Example 3: An assessed value of $1,200,000 results in an estimated annual secured property tax of approximately $14,192. These examples use the official secured property tax rate but do not include exemptions, penalties, supplemental assessments, escape assessments, or parcel-specific charges that may appear separately on an official San Francisco property tax bill.

What affects your property tax

- Assessed value determined by the Assessor-Recorder - Official secured property tax rate - Voter-approved bond debt and local assessments - Supplemental assessments after a sale, ownership change, or new construction - Parcel-specific charges, exemptions, corrections, or penalties Properties with similar market values can have different property tax bills because assessed value history, ownership changes, exemptions, and parcel-specific charges can differ.

Limitations and important notes

This calculator provides an estimate only and does not replace an official San Francisco property tax bill. Actual amounts may differ because of exemptions, supplemental assessments, escape assessments, parcel-specific charges, penalties, corrections to assessed value, or other property-specific factors. Official property tax bills are issued by the San Francisco Treasurer & Tax Collector. Assessed values are determined by the San Francisco Office of the Assessor-Recorder. Always confirm your final amount using your official tax bill or the appropriate San Francisco tax authority.
