San Bernardino Property Tax Guide: Pay, Search, Due Dates & Exemptions

San Bernardino property tax is handled at the county level, so the right starting point is the county tax record, not a generic payment page. A missing bill, old PDF, supplemental assessment, wrong mailing address, mortgage escrow payment, or missed exemption can change what you should do next.

This guide explains the full process in plain English: how to search by parcel, how to pay safely, when secured taxes are due, how to read the bill, which exemptions to check, and when to contact the Tax Collector, Assessor, Board of Equalization, or another official office.

Quick Answer

To handle San Bernardino property tax safely, search the parcel first, confirm the Assessor Parcel Number, open the current secured or supplemental bill, check the tax year and installment, verify whether a payment has posted, review exemptions or value concerns, then pay only through the official San Bernardino County Auditor-Controller/Treasurer/Tax Collector payment route.

Important: Do not pay from an old saved bill or search result. A payment, supplemental bill, penalty, correction, exemption, refund, or mortgage escrow action can change the live balance.

New Homeowner Guide: Supplemental Bills, Escrow and Exemptions

New owners in San Bernardino County often receive more than one tax-related notice. A regular secured bill, supplemental assessment, lender escrow statement, and Homeowners’ Exemption form can all arrive at different times.

🏡 Official action: review new homeowner information
  1. Read the county’s new homeowner page.
  2. Check whether your lender will pay the next tax bill from escrow.
  3. Watch for supplemental tax bills after purchase or new construction.
  4. Apply for the Homeowners’ Exemption if the home is your principal residence.
  5. Update mailing address if the bill still shows seller or old owner information.
Read New Homeowner Information

New buyer warning: A seller credit at closing does not always mean the county bill is paid. Compare your closing statement with the official tax record and escrow setup.

Supplemental Property Tax Bills

A supplemental bill can happen after a change in ownership or new construction. It is separate from the regular annual secured bill. New owners sometimes miss it because they expect the mortgage company or closing escrow to handle everything.

📌 Why it happens

The Assessor may reassess the property after purchase, transfer, or construction. The difference can create a supplemental bill or refund.

🧾 Why it confuses owners

The regular secured bill and supplemental bill can have different bill numbers, due dates, and balances.

🏦 Escrow issue

Mortgage escrow does not always automatically pay supplemental bills. Ask your servicer directly.

✅ What to keep

Closing statement, deed, supplemental notice, regular tax bill, escrow disclosure, and payment proof.

Assessment Appeals, Proposition 8 and Value Questions

Refunds, Overpayments and Unclaimed Money

Late, Delinquent, Tax Sale or Defaulted Taxes

  1. Search your tax record and identify the unpaid bill year.
  2. Check whether the bill is secured, supplemental, unsecured, delinquent, or tax-defaulted.
