Illustration for: Does your property tax really go where they say? How to follow the money in San Francisco and the Bay Area

First-time Bay Area homeowner series, part 3. It's the question every new homeowner asks when the bill arrives: does this money actually go where they say? The honest answer is: mostly yes, the rules are strict, and you can check it yourself. It just takes some digging, and AI can make the digging much faster.

Your bill has two parts

1. The base 1% (Prop 13). This is the general tax, about 1% of your assessed value. It isn't earmarked for one project. It's split by formula among local agencies. In a 2019 Santa Clara County breakdown published with the assessor's annual report, the split looked like this:

Share of the 1%

  • Public schools: 44% (media report)
  • County: 18% (media report)
  • Cities: 13% (media report)
  • Redevelopment trust fund: 12% (media report)
  • Community colleges: 7% (media report)
  • Special districts: 6% (media report)

San Francisco is a city and county in one, so its split looks different. It's also one of a handful of counties that generates "excess ERAF": money shifted toward schools under a state formula that, once school minimums are met, comes back to local government. A 2022 court ruling let San Francisco keep about $42 million a year of it, the SF Standard reported.

2. Voter-approved add-ons. Bonds, parcel taxes and special assessments are listed line by line on your bill, usually with a phone number. Unlike the 1%, these are restricted: a school bond can only be spent on the projects in the measure voters approved.

Who checks the spending

  • School bonds passed with a 55% vote must have an independent citizens' oversight committee and annual audits under California law.
  • San Francisco's city bonds are reviewed by the Citizens' General Obligation Bond Oversight Committee, and the Controller's Office publishes reports on how bond money is spent.
  • Before you vote, San Francisco's Controller writes a letter in the voter guide estimating what each bond will cost property owners.

So the money is tracked. Whether it's spent well is a different question, and that's where your attention as a voter matters.

Use AI to follow the money

Oversight reports and audits can run to hundreds of pages. An AI assistant is great at the first pass.

  1. Find the documents. Search your county or school district site for "bond oversight committee annual report" or "audit".
  2. Ask for a summary. Upload the PDF and ask: "What was this bond for, how much has been spent, on which projects, and are any behind schedule or over budget?"
  3. Ask for the page numbers. Then open those pages and confirm. AI can misread tables or invent details, so never repeat a figure you haven't checked.
  4. Match it to your bill. Ask the AI to list each line on your tax bill and what agency it funds, then call that agency's number with any questions.

What it means for you

  • Read your bill once, line by line. Each add-on has a name and a contact number. You'll know exactly what you're paying for.
  • Read the Controller's cost letter before you vote. It tells you what a measure would add to bills.
  • Ask questions in public. Oversight committee meetings are open, and many take public comment.
