Auditor-Controller/ Treasurer/ Tax Collector
The San Bernardino County Auditor-Controller/Treasurer/Tax Collector combines several financial, tax collection, accounting, auditing, treasury, and debt recovery functions within one county department. Residents, property owners, businesses, County agencies, and other users may interact with different divisions depending on the issue involved. This article explains the major responsibilities of the department, how to identify the correct division, how property tax and other payment services work, which official online systems are available, what information to review before completing a transaction, and common mistakes that can send a request to the wrong office.
Department Roles and Services
The Auditor-Controller/Treasurer/Tax Collector, commonly identified by the County as ATC, oversees a broad range of financial responsibilities. Those duties are divided among specialized operations rather than handled through a single service desk.
The department's major functions include collecting property taxes, managing County funds and investments, operating financial controls, conducting internal audits, maintaining property tax calculations and allocations, and collecting certain debts owed to County agencies. Because these functions are different, knowing which division owns a particular service is one of the most useful steps a resident can take before submitting a payment, question, or request.
The department also emphasizes independence and transparency in its financial work. According to its official information, the Auditor function serves as a fiscal oversight role, the Controller oversees the proper and efficient handling of funds, the Treasurer manages County funds and the investment pool, and the Tax Collector collects tax amounts owed to the County.
Which Division Handles Your Issue?
A property tax payment question is generally different from a question about how property tax dollars are calculated or distributed. A request involving a County debt is also different from a property tax bill. Separating these services can prevent delays and reduce the chance of contacting a division that cannot resolve the issue.
Tax Collector Division
The Tax Collector Division is responsible for tax collection, tax collection accounting, and tax sales. Its services include online property tax payments, tax sale information, Transient Occupancy Tax, mobile home tax clearance certificates, bulk payments, penalty cancellation requests, delinquent unsecured taxes, and estimates of new tax bills.
The division also publishes information about ACH and wire payments, new homeowner issues, postmarks, tax bill interpretation, fees, and office closure schedules. Someone trying to pay a tax bill, understand a payment-related issue, request a tax clearance certificate, or address a delinquent unsecured tax matter should distinguish those tasks from property tax accounting work performed by the Property Tax Division.
Property Tax Division
The Property Tax Division handles the accounting and allocation side of the property tax system. Its responsibilities include compiling assessed valuations, calculating tax rates, preparing tax rolls, maintaining tax charges, processing tax bill corrections, issuing refunds, and allocating collected property taxes.
The division also manages property tax apportionment, tax rate books, direct charges, unclaimed property tax refunds, subdivision maps, public acquisitions, redevelopment-related tax functions, and the Redevelopment Property Tax Trust Fund. The County states that this division apportions property taxes to approximately 600 entities.
This distinction matters when a taxpayer's concern is not simply making a payment. A person looking for an unclaimed property tax refund, information about tax rates, a tax roll correction, or information about how collected property tax revenue is distributed is dealing with a different function from the Tax Collector's payment operation.
Treasurer Division
The Treasurer Division serves as fiduciary and custodian of County funds. It provides banking services to County departments and to voluntary and involuntary participants in the County's investment pool. It also manages that investment pool.
Official Treasurer services include investment pool management, Fitch ratings reports, a Treasury Portal, broker/dealer applications, investment dashboards, portfolio performance reports, and other Treasurer reports. These services are generally institutional and financial-management functions rather than property tax payment services for individual taxpayers.
Controller Division
The Controller Division designs and operates the County's financial control system. Its stated purpose is to provide reasonable assurance related to operational effectiveness and efficiency, reliable financial reporting, and compliance with laws, regulations, and applicable policies.
The division's listed services include general accounting, management services, and financial reports. A person looking for County financial reporting or Controller-related accounting information should not confuse this work with tax collection or treasury investment management.
Internal Audits Division
The Internal Audits Division conducts operational and compliance audits of County departments and agencies. It provides objective appraisals and recommendations intended to improve operations and also manages the County's fraud, waste, and abuse reporting function within ATC.
Its services include internal audits, internal audit reports, single audit work, Certified Statements of Assets Transferred, bank account matters, prepaid cards, relief from liability or cash shortages, discharge from accountability, and cash funds.
Residents who want to review published internal audit material or use the department's fraud, waste, and abuse reporting service should use this division rather than the Tax Collector or Revenue Recovery.
Revenue Recovery Division
The Revenue Recovery Division provides debt collection services to County agencies. Its listed areas include collection services, victim restitution, legal enforcement, delinquent unsecured taxes, monies held in trust by the Treasurer, and County bill payment services.
This division is especially important to distinguish from the property tax payment system. A Revenue Recovery bill, restitution obligation, court fine, or other debt being collected for a County agency is not automatically handled through the same process used for a secured property tax bill.
Property Tax Online Services
Property owners who need to view or pay County property taxes can use the official property tax online services. The County promotes online payment as a fast and secure option that provides instant confirmation and is available 24 hours a day.
The payment page also provides access to property tax payment history. Users managing many parcels or accounts can use the bulk-add feature, which supports payment for up to 3,000 accounts in one upload and requires a login.
Before submitting a payment, users should make sure they are working with the property tax service rather than another County payment system. Revenue Recovery, for example, maintains services for debts collected on behalf of County agencies. Paying through the wrong system could leave the intended obligation unresolved.
Partial Property Tax Payments
ATC launched a partial payment option for secured property taxes. The program allows taxpayers to make smaller payments during the year instead of waiting to submit the entire installment at once.
Partial payments do not change the deadlines that apply to the required installments. The County states that the full installment must still be paid by the applicable state deadline to avoid penalties. Taxpayers therefore should not assume that making one or more partial payments automatically prevents a delinquency if the remaining installment balance is still unpaid when the deadline arrives.
The County states that partial payments may be made online, by phone, by mail, or in person. Anyone using partial payments should keep track of the remaining amount due and confirm that the complete installment has been satisfied by the required deadline.
Mail Payment Safety
The Tax Collector has issued a property tax payment safety alert because of increased mail theft and check fraud. The department advises taxpayers to avoid mailing checks and promotes its online payment system as an alternative with immediate confirmation.
If a taxpayer chooses a payment method that does not provide immediate confirmation, keeping transaction records becomes especially useful. A payment should not be assumed complete simply because it was initiated. The official online service's confirmation feature provides a direct way to verify that an electronic transaction has been submitted through the County system.
Property Tax Dates and Penalties
The Tax Collector publishes important property tax dates on its official site. The division states that original secured property tax bills are mailed in October. It also identifies October 31 as the date unsecured tax bills go into default if they are not paid by 5:00 p.m., with a 1.5% penalty added each month to unpaid tax amounts.
Because different types of property tax obligations can follow different processes, taxpayers should first identify whether they are dealing with a secured or unsecured bill. The distinction can affect which deadline or delinquency rule applies.
The Tax Collector also provides information about understanding postmarks. This is relevant for users who plan to send a tax payment rather than pay electronically. Mailing a payment and completing an electronic payment are not interchangeable procedures, and users should rely on the Tax Collector's official instructions for the method they choose.
Secured and Unsecured Tax Issues
The reference material identifies both secured property taxes and delinquent unsecured taxes within ATC services. Secured property taxes are the subject of the County's property tax payment system and its partial payment program. Delinquent unsecured taxes also appear among the services provided by the Tax Collector and Revenue Recovery.
Because an unsecured tax account may move into delinquent collection activity, users should pay attention to the office or system named on the bill or notice they have received. A property tax payment page, a Revenue Recovery bill payment service, and other County collection functions should not be treated as one interchangeable payment channel.
When reviewing a notice, users should identify the type of obligation and the County division associated with it before making a payment. This can be especially useful when a person has more than one County-related balance at the same time.
Penalty Cancellation Requests
The Tax Collector offers a penalty cancellation request form for secured or unsecured property tax bills. This is a specific Tax Collector process rather than a general request to erase or adjust a County debt.
Users should make sure the penalty they are questioning is connected to a secured or unsecured property tax bill before using that process. A charge associated with Revenue Recovery, a court fine, restitution, or another County obligation belongs to a different collection function.
The reference information does not treat the availability of a request form as a guarantee that a penalty will be cancelled. The appropriate approach is to use the official form for the applicable property tax bill and provide the information requested through that process.
Tax Sale Services
Tax sales are part of the Tax Collector Division's responsibilities. The department provides a dedicated tax sale service along with its property tax collection functions.
Tax sale matters should not be confused with an ordinary current-year property tax payment. Someone looking for information about tax-defaulted property or a County tax sale should use the Tax Collector's tax sale information rather than assuming that the standard payment page contains all tax-sale procedures.
The ATC site also publishes notices concerning property tax delinquency and impending power to sell tax-defaulted property. Because tax sale matters involve specific notices and procedures, users should rely on the County material associated with the affected property rather than general assumptions about delinquent taxes.
Transient Occupancy Tax Services
ATC also handles Transient Occupancy Tax, commonly abbreviated as TOT. The Tax Collector's listed services allow users to pay Transient Occupancy Tax or apply for a TOT certificate.
This service is separate from ordinary secured property tax payments. A business or operator dealing with Transient Occupancy Tax should use the TOT function identified by ATC rather than the standard property tax payment workflow.
The department's published achievements report substantial growth in TOT collections following enhanced collection efforts and voluntary collection agreements. For users, the practical point is that TOT has its own service area within the Tax Collector's operations and should be treated as a distinct tax obligation.
Mobile Home Tax Clearance
The Tax Collector provides a Mobile Home Tax Clearance Certificate service. Users can request a clearance certificate and check the status of an existing request through the department's service offerings.
A mobile home tax clearance certificate is not the same transaction as paying a regular secured property tax installment. Someone who specifically needs a clearance certificate should use the certificate process rather than relying only on the general property tax payment service.
Property Tax Refund Functions
The Property Tax Division handles unclaimed property tax refunds and tax bill corrections. The department also allocates excess tax proceeds as part of its property tax responsibilities.
Taxpayers looking for money that may be owed back to them should distinguish an unclaimed property tax refund from a payment reversal or a general request to change a tax bill. The County lists unclaimed refunds, roll changes, bill corrections, and excess proceeds within the Property Tax Division's broader accounting responsibilities.
The ATC homepage also provides direct access to unclaimed property tax refund information. Users should rely on the official County process for these funds rather than assuming an unclaimed refund will automatically be applied to another bill.
How Property Taxes Are Distributed
ATC provides a service showing where property tax dollars go. The information can be viewed at the tax rate area and taxing-agency jurisdiction level. This function is useful for users who want to understand distribution rather than simply determine how much they owe.
The Property Tax Division is responsible for apportioning collected property taxes and administering related allocation processes. Its duties include the Redevelopment Property Tax Trust Fund, projections of tax collections, pass-through calculations, and other tax increment financing functions.
This is different from the Tax Collector's job of collecting the money. A question about a payment's receipt belongs on the collection side, while a question about the allocation or distribution of collected property tax funds is tied to the Property Tax Division.
County Treasury and Investments
The Treasurer manages County funds and the County investment pool. The Treasury acts as custodian of County funds and provides banking services for County departments as well as participants in the investment pool.
Official Treasurer information includes portfolio performance reports, investment dashboards, investment pool ratings, mandated duties, and broker/dealer application information. These services are separate from individual property tax accounts even though the Treasurer and Tax Collector are part of the same elected department.
Users researching County financial management should therefore look at Treasurer reports and investment information rather than the property tax payment pages.
County Accounting and Reporting
The Controller Division operates financial control systems intended to support reliable financial reporting, efficient operations, and compliance. The ATC site also publishes County financial reports through its Controller-related services.
This accounting function helps explain why the combined department covers more than tax collection. The Controller side deals with County financial controls and reporting, while the Tax Collector side focuses on collecting taxes, and the Treasurer manages County funds and investments.
Residents reviewing County financial reports should identify the report type they need rather than treating a property tax bill as a source of general County accounting information.
Audits and Fraud Reporting
The Internal Audits Division conducts operational and compliance audits of County departments and agencies. Its audit reports provide objective evaluations and recommendations concerning County operations.
The division also manages the fraud, waste, and abuse hotline function identified by ATC. That reporting channel is designed for allegations involving fraud, waste, or abuse rather than ordinary disagreements about a tax bill, payment status, or County debt.
Using the correct process matters here. A taxpayer with a payment issue should use the Tax Collector's service channels. A person dealing with a Revenue Recovery obligation should use that division. Allegations of fraud, waste, or abuse fall within Internal Audits.
Revenue Recovery Payments
Revenue Recovery collects debts for County agencies and provides services involving victim restitution, legal enforcement, delinquent unsecured taxes, and other County bills. The division also provides access to a County bill payment site.
People receiving a Revenue Recovery notice should treat the identifying information on that notice as separate from a property tax bill. A Revenue Recovery obligation may involve a court fine, restitution, a delinquent account, or another debt assigned to the division for collection.
Before sending money, users should verify that they are using the payment channel associated with the debt shown on their notice. The existence of several ATC payment-related services makes this distinction particularly important.
Preparing Before You Contact ATC
Before using an online service or contacting a division, review the document, bill, or notice that created the question. The most useful information is the information already associated with the transaction or account you are trying to address.
Depending on the service involved, users may need to distinguish among:
A secured property tax bill.
An unsecured tax bill.
A Revenue Recovery bill or debt notice.
A Transient Occupancy Tax matter.
A mobile home tax clearance certificate request.
An unclaimed property tax refund or tax roll issue.
A County financial report or audit matter.
A Treasury or investment-pool matter.
Keeping these categories separate can help a user select the right online service and avoid sending a question to a division that handles a different part of the County's financial operations.
Common Service Mistakes
One common mistake is treating every ATC service as part of the Tax Collector. The department contains several divisions with distinct responsibilities. Property tax collection, tax accounting, County investment management, financial controls, internal auditing, and debt recovery are related through the department's financial mission but are not the same service.
Another mistake is assuming that a partial payment changes a tax deadline. ATC specifically states that taxpayers using partial payments must still complete the full installment by the applicable state deadline to avoid penalties.
Users should also avoid confusing a Revenue Recovery payment with a property tax payment. Revenue Recovery collects debts for County agencies, while the Tax Collector handles property tax collection and related tax services.
For mailed payments, users should be aware of the County's warning about mail theft and check fraud. The department promotes online property tax payment because it provides instant confirmation and around-the-clock access.
Finally, requests involving birth certificates, death certificates, marriage licenses, ceremonies, fictitious business names, document recording, or other Recorder/Clerk functions are outside the services described here. The ATC contact information page directs those matters to the Assessor-Recorder-County Clerk rather than the Auditor-Controller/Treasurer/Tax Collector.

Auditor-Controller/ Treasurer/ Tax Collector FAQs
Where can I check the current property tax calendar?
The official Tax Collector page maintains an important-dates section for property tax activity. This is the better place to verify the schedule for the tax year you are dealing with instead of relying on an old bill, saved calendar, or previous year's deadline information. Taxpayers can also review the County's guidance on postmarks when timing a mailed transaction.
Is property tax postponement information available through the County?
Yes. Property Tax Postponement is listed among the official Tax Collector resources. Because postponement is different from changing a tax bill or requesting cancellation of a penalty, taxpayers looking into this option should start with the Tax Collector's official services and resources and follow the County information provided for that program.
Where should a new homeowner look for tax guidance?
The Tax Collector provides a dedicated New Homeowner Information section. It is useful when a recently purchased property creates questions about County tax billing or the notices connected with a new ownership period. The same official page also provides guidance for understanding a tax bill, payment instructions, and the Tax Collector's current fee schedule, allowing homeowners to check County instructions rather than relying on assumptions from a prior owner's bill.
How can I verify office hours before visiting?
Operating hours differ among divisions, so visitors should check the County's hours and locations page before making an in-person trip. The page separates Tax Collector, Property Tax, Revenue Recovery, Internal Audits, Controller, Treasurer, and other operations by floor and business schedule. Checking the current listing is especially useful around County holidays or when a division follows a different daily schedule from other offices in the same building.
