When Can You Appeal Property Taxes In San Francisco?

San Francisco, a hub of tech innovation and one of the most expensive real estate markets in the world. But what about property taxes?

When Can You Appeal Property Taxes In San Francisco?

In San Francisco, as in other parts of California, property taxes are assessed by the county. The San Francisco Office of the Assessor-Recorder is responsible for determining property values. If you believe your property has been over-assessed, you can appeal the valuation. Here's a general overview of the appeal process and timing:

Regular Assessment Appeal Period:

The regular appeal period for filing an assessment appeal in San Francisco (and throughout California) is from July 2 through September 15. This is when you can contest the regular assessed value of your property.

Supplemental or Escape Assessment Appeals:

If you receive a notice for a "supplemental" or "escape" assessment (outside of the regular assessment), you have 60 days from the mailing date of the notice to file an appeal.

Here's What You Will Need

Preparing for Your Appeal:

  • Research Comparable Sales: One of the most compelling pieces of evidence you can provide is recent sales data of comparable properties in your area that support your claim that your property's assessed value is too high.
  • Gather Documentation: Any documentation or evidence you can provide to support your case will be helpful. This can include photographs of your property showing defects or needed repairs, contractor estimates for repairs, or other documentation that might affect the property's value.
  • Understand the Appeal Process: Familiarize yourself with the local rules and processes for property tax appeals. The San Francisco Assessment Appeals Board or the Office of the Assessor-Recorder should have resources to guide you.
  • Be Ready to State Your Case: If you're asked to attend a hearing, be prepared to clearly and succinctly state your case and provide evidence to support your claim.

Here's How To File

You'll need to file a formal application with the San Francisco Assessment Appeals Board. There's usually a form to fill out where you'll list details about your property and the reasons for your appeal. It's best practice to work with appeal consultants if you have a high value property to maximize your chances of appeal success.

Basics of Property Taxes:

Every homeowner in San Francisco is familiar with property taxes, a levy based on the assessed value of their property.

The Importance of Property Taxes in SF:

These taxes fund critical services like schools, public safety, and infrastructure projects. But what if you think you're being overcharged?

What Triggers the Need for an Appeal?

Ever felt that heart-sinking moment when your property tax bill arrived and it's much higher than you expected?

With the dynamic San Francisco real estate market, your property's assessed value can skyrocket.

Alternatively, if your property has suffered damage or its use has changed, its value may be lower than assessed.

The Timeline to Appeal

Time is of the essence when you're trying to save money! Here are the current deadlines.

Regular Appeal Window:

Typically, San Francisco property owners can appeal their taxes between July 2 and September 15. Missed the date? Don't worry.

Special Circumstances:

There are exceptions for special situations, such as a natural disaster affecting your property.

Potential Outcomes of an Appeal

Approval and Adjustments:

If the board finds in your favor, they will adjust your property's assessed value, reducing your tax bill.

Denial and Next Steps:

But if they don't? You can consider further legal actions or prepare for a more robust appeal next time.
