San Bernardino County Property Tax: Pay, Search, Due Dates & Exemptions Guide
San Bernardino County property tax is split across different county offices. The Assessor-Recorder-County Clerk handles assessed value, APN property records, exemptions, Prop 13, Prop 8 decline-in-value reviews, supplemental assessments and ownership updates.
The Auditor-Controller/Treasurer/Tax Collector handles tax bills, payments, penalties, refunds, tax rates and tax-sale collection work. This guide shows the correct route for paying, searching, checking due dates, filing exemptions and challenging an assessment.
Quick Answer: Start With the Correct San Bernardino County Office
Use the Tax Collector when you need to pay a bill, look up current tax balances, check installment status, request payment history, ask about penalties, or resolve a receipt issue.
Use the Assessor when you need property value, APN details, mailing address changes, Homeowners’ Exemption, Disabled Veterans’ Exemption, Prop 13 base-year questions, Prop 8 decline-in-value review, business property filing or supplemental assessment questions.
Fast Route: What Should You Do First?
This table helps you avoid the most common mistake: contacting the Tax Collector for an Assessor issue, or contacting the Assessor for a payment issue.
| Your Goal | Correct Office or Tool | Why | Next Step |
|---|---|---|---|
| Pay property tax | Auditor-Controller/Treasurer/Tax Collector | ATC bills and collects property taxes. | Search the tax bill and pay through the official ATC portal. |
| Search assessed value | Assessor Parcel Access | ARC maintains assessed value and parcel record data. | Search by APN, address or map tool. |
| Apply for Homeowners’ Exemption | Assessor Exemptions Unit | The Assessor processes exemption claims and cancellations. | File BOE-266 and watch February 15 / December 10 timing. |
| Dispute assessed value | Assessor review or Clerk of the Board appeal | Value disputes are assessment issues, not payment issues. | Request Prop 8 review or file an assessment appeal before the deadline. |
| Ask about a supplemental bill | Assessor first, then Tax Collector | Assessor creates supplemental assessment; Tax Collector bills and collects it. | Confirm change-of-ownership or new-construction reason. |
| Mortgage escrow issue | Tax Collector and lender | Payment posting is tax-collector data, but escrow funding is lender data. | Search payment history and contact your loan servicer. |
San Bernardino County Property Tax Due Dates
California secured property taxes are billed in two installments. The legal due dates and delinquency dates are different, so pay attention to both lines on the bill.
| Tax Item | Due Date | Delinquent After | What to Do |
|---|---|---|---|
| 1st secured installment | November 1 | December 10 | Pay early, especially if mailing a check or coordinating escrow. |
| 2nd secured installment | February 1 | April 10 | Do not wait for a second reminder if your lender does not pay. |
| Unsecured tax bills | August 1 | August 31 | Used for some business, personal property or other unsecured tax accounts. |
| Supplemental bills | Shown on the supplemental bill | Shown on the bill | Read carefully because supplemental timing differs from annual bills. |
| Weekend or holiday | Official date may shift | Usually next business day treatment if deadline falls on weekend/holiday | Check the current ATC important dates page before relying on a shift. |
- Open San Bernardino County ATC’s official Important Dates page.
- Check the current tax year and bill type.
- Confirm whether you are paying secured, unsecured or supplemental taxes.
- Save the delinquency date, not only the due date.
- Pay before the penalty date and keep confirmation.
How to Search San Bernardino County Property Tax Records
Use two different searches depending on your goal. The Assessor search helps with property value and APN information. The Tax Collector search helps with tax bills, balances, payment history and receipts.
The most reliable identifier is the Assessor’s Parcel Number, often called APN. Address searches can work, but spelling, unit numbers, new subdivisions and mailing-address differences can cause confusion.
| Search Type | Use It For | Best Search Key | Official Route |
|---|---|---|---|
| Assessor Parcel Access | Assessed value, APN, parcel details and property characteristics. | APN or property address. | ARC Property Information |
| Tax bill search | Bill balance, installments, amount due and payment status. | APN, bill number, address or account details. | ATC Property Tax Search |
| Payment history | Receipts, paid status, old payments and escrow confirmation. | Parcel or bill information. | ATC Online Services |
| Recorder records | Recorded deeds, ownership documents and legal-record research. | Document number, name or recording details. | ARC Recorder-Clerk |
- Search the Assessor record first if you are checking value, APN or property details.
- Search the Tax Collector record when you are ready to pay or verify a balance.
- Match APN, situs address, owner mailing details and tax year.
- Check if there are annual, supplemental, corrected or defaulted bills.
- Save screenshots or PDF records for your files before making a payment.
How to Pay San Bernardino County Property Tax
San Bernardino County ATC provides online tax services for property tax lookup and payment. The portal may show current tax bills, payment history, active bill balances and related forms.
Before paying, confirm the parcel, bill type, tax year, installment number and amount due. This is important if you recently bought the property, refinanced, have escrow, or received a supplemental bill.
- Open the official San Bernardino County ATC property tax page.
- Search by the available parcel, bill, address or account fields.
- Review all open bills and installments before paying.
- Choose an official payment method shown by the portal.
- Save the confirmation and check payment history after processing.
Payment safety tip: Start from the official San Bernardino County ATC site. Avoid payment links from ads, random emails or text messages unless they clearly route through the county’s official payment system.
How to Read Your San Bernardino County Property Tax Bill
Your tax bill is not the same as your assessment record. The Assessor sets assessed value and exemption status. The Tax Collector bills and collects the amount after tax rates, special assessments, exemptions and other charges are applied.
| Bill Area | What It Means | What to Check |
|---|---|---|
| APN | Assessor’s Parcel Number used to identify the property. | Match it to deed, assessor record, tax bill and escrow records. |
| Bill type | Annual secured, supplemental, unsecured, corrected or defaulted bill. | Supplemental bills are separate from normal annual tax bills. |
| Installment | The first or second installment amount for secured taxes. | First installment delinquent after Dec 10; second after Apr 10. |
| Assessed value | Value used to calculate ad valorem property tax. | Compare with the Assessor record if it changed sharply. |
| Special assessments | Charges from agencies or districts may appear on the bill. | These may not be controlled by the Assessor. |
| Penalty or delinquency | Extra charges when payment misses the delinquency deadline. | Contact ATC before assuming a waiver applies. |
How Proposition 13 Affects San Bernardino County Property Tax
Proposition 13 limits the general property tax rate to 1% of assessed value, plus voter-approved debt and other allowed charges. It also generally limits annual increases in assessed value unless there is a change in ownership, new construction or another reassessment event.
This is why two similar homes may have very different tax bills. A long-time owner may have a lower factored base-year value, while a new buyer may be reassessed closer to purchase value.
| Prop 13 Topic | Plain Meaning | What to Check |
|---|---|---|
| Base-year value | Value set when ownership changes or new construction occurs. | New buyers should expect reassessment after closing. |
| Annual inflation limit | Assessed value generally cannot increase by more than 2% per year unless reassessed. | Review whether a change in ownership or new construction triggered a new value. |
| Prop 8 decline in value | Temporary reduction may apply if market value falls below the Prop 13 factored value. | Submit decline-in-value review or file an appeal if the value is too high. |
| Tax rate | The exact rate depends on tax area and bonded debt. | Use ATC or Auditor-Controller rate information for exact parcel tax rates. |
San Bernardino County Property Tax Exemptions
The Assessor administers many property tax savings programs. The most common homeowner benefit is the Homeowners’ Exemption for an owner-occupied principal residence.
The Homeowners’ Exemption reduces assessed value by $7,000, which is commonly about $70 in annual tax savings. The full exemption generally requires timely filing, and a reduced amount may be available when filed later in the year.
| Exemption or Relief | Who It May Help | Key Rule |
|---|---|---|
| Homeowners’ Exemption | Owners who occupy the property as their principal residence as of January 1. | File BOE-266; timely deadline is generally 5 p.m. February 15 after ownership change. |
| Late Homeowners’ Exemption | Eligible owners who miss the full-exemption deadline. | 80% of the full exemption may be available if filed between February 16 and 5 p.m. December 10. |
| Disabled Veterans’ Exemption | Qualified 100% service-connected disabled veterans or eligible unmarried surviving spouses. | Standard and low-income versions have different filing and documentation requirements. |
| Veterans’ Exemption | Certain qualified veterans under California exemption rules. | Use official BOE/Assessor forms and verify current eligibility. |
| Institutional or nonprofit exemption | Certain churches, nonprofit colleges, museums, schools, libraries and qualifying organizations. | Property use and annual filing rules matter. |
| Property Tax Postponement | Some senior, blind or disabled homeowners with qualifying principal residences. | This is a state program and is different from an exemption. |
- Open the San Bernardino County Assessor property tax savings page.
- Select Homeowners’ Exemption, Disabled Veterans’ Exemption or another relief program.
- Confirm the form, deadline and documents.
- Submit the form through the official Assessor route.
- Notify the Assessor if you move out, transfer title or no longer qualify.
Supplemental Property Tax Bills After Buying or Building
A supplemental assessment happens when state law requires the Assessor to reappraise property due to a qualifying change in ownership or new construction. The supplemental assessment reflects the difference between the new assessed value and the prior assessed value for the affected period.
Supplemental bills are separate from annual secured bills. A new owner can receive one or more supplemental bills after closing, even if the regular annual bill was handled through escrow.
| Situation | Why a Supplemental May Happen | What to Do |
|---|---|---|
| Home purchase | Change in ownership can establish a new base-year value. | Budget for a supplemental bill after closing. |
| New construction | New improvements can be assessed separately. | Keep permits, completion dates and contractor records. |
| January 1 to June 30 change | The Assessor FAQ says two supplemental tax bills may be issued for changes in this period. | Read every bill’s tax year and installment dates carefully. |
| Escrow account | Mortgage servicers may not automatically pay supplemental bills. | Ask the lender and verify ATC payment history. |
Prop 8 Decline-in-Value Review
A Prop 8 value is a temporary reduction when current market value falls below the Prop 13 adjusted base-year value. This can happen in a declining market, after damage, or when comparable sales support a lower value.
San Bernardino County Assessor guidance says owners may request a free Prop 8 decline-in-value reassessment by submitting the ARP-068 form between January 1 and December 31.
- Search the current Assessor value for your APN.
- Collect comparable sales, appraisal, photos or repair evidence.
- Open the Assessor’s Prop 8 decline-in-value page.
- Submit ARP-068 between January 1 and December 31.
- Use a formal assessment appeal if you need board review by the appeal deadline.
San Bernardino County Assessment Appeals
An assessment appeal challenges assessed value or certain legal assessment issues. It does not replace paying your tax bill. If a bill is due while an appeal is pending, continue checking payment deadlines with ATC.
The Clerk of the Board provides administrative support for San Bernardino County assessment appeals. The 2026 regular assessment filing period is listed as July 2, 2026 through November 30, 2026, and each application requires a $45 non-refundable administrative processing fee unless a valid waiver is accepted.
| Appeal Topic | What It Means | Practical Tip |
|---|---|---|
| Regular assessment appeal | Used for annual roll value disputes and decline-in-value appeals. | Check the current year filing period before submitting. |
| Supplemental appeal | Used when disputing a supplemental assessment after ownership change or construction. | Use the supplemental notice date and appeal type rules. |
| Clerk review | The Clerk reviews applications for completeness and scheduling. | Respond quickly if the Clerk requests missing information. |
| Hearing response | You may need to confirm attendance, request postponement or withdraw. | San Bernardino County materials mention a 21-day timing rule for hearing response forms. |
| Evidence | The board needs facts supporting your requested value. | Use comparable sales, appraisals, photos, repair estimates and property records. |
- Open the Clerk of the Board assessment appeals page.
- Select the correct appeal type and filing period.
- Enter APN, owner, value requested and reason for appeal.
- Include the processing fee or complete waiver request if eligible.
- Prepare evidence before the hearing date.
Business Property Statement and Unsecured Taxes
Business personal property is taxable unless exempt by law. San Bernardino County’s Business Property guidance says the BOE Form 571-L must be filed for business property operated or located in the county, detailing supplies, equipment and fixtures as of January 1.
The property statement due date is April 1. If e-filed or postmarked after May 7 at 5 p.m., the Assessor guidance states a 10% late filing penalty applies.
| Business Topic | Official Detail | Owner Action |
|---|---|---|
| January 1 status | Report business assets as of January 1. | Keep asset lists, invoices, depreciation schedules and location details. |
| 571-L statement | Standard BOE business property statement form. | File with the Assessor if required. |
| April 1 due date | Business property statement is due April 1. | Do not wait until May to prepare inventory. |
| May 7 penalty date | Late filing after May 7 at 5 p.m. can trigger 10% penalty. | File or postmark before the deadline. |
| Unsecured taxes | Some business or personal property bills are unsecured. | Watch August unsecured tax deadlines. |
Disaster, Calamity and Damaged Property Relief
If property is damaged or destroyed by misfortune or calamity such as fire, earthquake or other qualifying event, San Bernardino County Assessor guidance says reassessment relief may be available for eligible assessable property.
This is not automatic. Owners should act quickly, document the damage, save repair estimates and use the correct Assessor disaster relief form.
- Take dated photos of the damage.
- Save repair estimates, insurance documents and inspection reports.
- Confirm the property type is eligible for reassessment relief.
- Open the Assessor disaster relief page and use the proper form.
- Keep copies and watch for revised assessment or bill instructions.
Mortgage Escrow, New Buyers and Missing Bills
A lender escrow account does not remove the owner’s responsibility to make sure taxes are paid. New buyers should watch for annual and supplemental bills because lenders may not automatically pay every supplemental bill.
Confirm each installment posted on the ATC payment history page after the due date.
Search the APN after closing, check mailing address, file Homeowners’ Exemption if eligible, and budget for supplemental bills.
Use the Tax Collector search or request help before the delinquency date. Do not wait because a bill did not arrive.
Save confirmation and contact ATC with APN, bill number, date paid and payment proof.
Late Payments, Penalty Waivers and Refund Questions
First and second secured installments become delinquent after the listed delinquency dates. A penalty waiver is not automatic, even if the issue was caused by escrow confusion, mail delay or user error.
San Bernardino County ATC provides an online penalty waiver request route and payment-history tools. Read the requirements before assuming your situation qualifies.
- Search the ATC property tax account immediately.
- Confirm bill type, tax year, installment and penalty amount.
- Review ATC’s penalty waiver request page if you believe waiver grounds apply.
- Contact escrow or lender if they were supposed to pay.
- Keep payment proof and check posting after processing.
Common San Bernardino County Property Tax Mistakes to Avoid
Most problems happen because owners use the wrong office, wait for the tax bill to dispute value, ignore supplemental bills, or assume the mortgage company handled everything.
Always match the APN before payment, especially for lots, condos, inherited property or multiple parcels.
These are the key secured-tax delinquency dates. Pay before the penalty date.
Assessment appeal windows are strict. Review value early and use the correct appeal type.
Supplemental bills after purchase or construction are separate from annual secured bills.
If the home is no longer your principal residence, notify the Assessor.
Prop 13 is the base-year value system; Prop 8 is a temporary decline-in-value review.
