San Mateo County, California

Where to obtain records

San Mateo County Tax Collector / Property Tax Records

How to find the information

The Treasurer-Tax Collector separates secured and unsecured tax guidance and links View/Pay Property Taxes. A live agent is available through 866-220-0308. Request the existing unpaid secured account ledger, statement or redemption amount and distinguish it from unsecured personal-property debt.

For an existing delinquent secured-property report, parcel account/payment ledger, bill copy or dated redemption amount, provide the parcel/account/assessment reference, fiscal years, desired as-of date and inspection or electronic-copy format. Ask which current, supplemental, defaulted and payment-plan amounts are included, whether recent payments have posted, and whether any power-to-sell or sale status applies. Confirm record-copy, certification, research or extract fees. A valuation roll, recorded lien, payment screen or dated sale inventory does not certify today’s unpaid balance.

What to ask for

“I am looking for publicly available delinquent real-property tax records for San Mateo County for [tax year]. Which office maintains these records? Is there an online search or downloadable list? If not, how can I request a copy, and what fees apply?”

Have the property address, parcel number, owner name, and tax year ready when searching for a particular property.

The linked payment entry could not be substantively retrieved; no result coverage or online payoff was tested. No taxpayer query, account registration, CAPTCHA verification, records-request submission, upload or payment was made. No taxpayer rows or owner-list attachments are included.
