San Bernardino County Tax Collector: Pay Online, Search, Phone & Address

San Bernardino County, California · property tax, APN search and payment guide

Pay, Search or Fix a San Bernardino County Tax Bill Safely

If you searched for the San Bernardino County Tax Collector, you probably need a phone number, email address, mailing address, online payment portal, APN search, property-tax receipt or late-tax answer.

The key is choosing the right county system first: ATC collects the tax, the Assessor handles value and mailing-address records, and the Clerk of the Board handles assessment appeals.

Payment safety warning: San Bernardino County officials warn that the Tax Collector does not initiate unsolicited calls or emails requesting secured property-tax payment. Do not use payment links from surprise emails, texts, robocalls or pressure notices. Open the official county site yourself.

Tax Lien Warning

⛔ Texas Attorney Fee Warning: After July 1, delinquent property taxes are referred to a collection attorney. An additional 15–20% attorney fee is added on top of your penalty and interest. On a $5,000 tax bill, this adds $750–$1,000 instantly. Pay before July 1 to avoid this.

Which San Bernardino County office should handle your problem?

The county has a newer unified ATC website, while older MyTaxCollector pages still appear in Google and may still route some tax searches. That creates confusion, especially near payment deadlines.

Pay / Balance

Use the Tax Collector / ATC for property-tax payments, balances, receipts, missed payments, delinquent accounts, partial payments, tax sale, redemption, mobile-home tax clearance and account payoff questions.

Value / Exemption

Use the Assessor-Recorder-County Clerk for assessed value, mailing-address changes, exemptions, change of ownership, parcel information, homeowner exemption and business property statement issues.

Appeal

Use the Clerk of the Board for assessment appeals. A filed appeal does not stop your responsibility to pay the tax bill on time.

Recorded Docs

Use Recorder-Clerk records for grantor/grantee index research, recorded deeds and document copies. A tax bill is not a full legal title report.

Local shortcut: San Bernardino, Fontana, Ontario, Rancho Cucamonga, Victorville, Hesperia, Redlands, Rialto, Chino, Apple Valley, Big Bear and Joshua Tree can all involve the same county Tax Collector if the parcel is in San Bernardino County. City name alone is not enough; confirm the APN and county.

Portal transition

San Bernardino County Tax Collector portal: new ATC site vs legacy MyTaxCollector

San Bernardino County announced a newer unified ATC website in 2025. At the same time, older MyTaxCollector pages still appear in search results and may still redirect or support specific legacy searches.

Start at the current ATC site

Use this first when you want the current county Tax Collector gateway, tax services and modern payment routes.

Open official SBCountyATC Tax Collector
Use legacy pages carefully

Legacy MyTaxCollector pages still describe APN search, eCheck/card payment, contact information, mobile-home clearance and tax-sale material.

Open legacy MyTaxCollector portal
Do not bookmark blindly: if an old search result redirects or shows a maintenance notice, go back to the current ATC domain and follow the county’s own link. Do not search for a replacement payment link on ads or map listings.
Official payment workflow

How to pay San Bernardino County property tax online

Open the county payment route. Start from the official ATC Tax Collector page or county-linked MyTaxCollector page before entering payment details.
Pick the correct bill type. Secured property, unsecured property, supplemental bills, defaulted taxes and mobile-home clearance are not always handled the same way.
Search with APN or bill information. For secured property, use the 13-digit APN with no dashes when possible. For unsecured accounts, use the unsecured property number or property ID shown on the bill.
Verify the account before checkout. Match San Bernardino County, APN, bill year, installment, amount and property information. Do not pay based only on a similar address.
Choose eCheck or card intentionally. County pages promote eCheck/checking-savings payment as free. Card payments use processor fees, so review the live fee before submitting.
Save proof and recheck history. Keep confirmation number, APN, bill number, tax year, installment and bank/card proof until the account history updates.
Payment cost check

San Bernardino County property tax payment fees and safe methods

Online eCheck

County pages promote checking/savings eCheck payment as free.

Card payment

Legacy portal language lists a 2.25% card processor fee with a $1.95 minimum; always verify the live checkout.

Phone payment

County notices list phone payment options including 909-387-8308 and other payment lines.

ACH / wire

Large aggregate annual payments of $50,000 or more may require ACH credit or wire transfer.

Card-fee examples using the older 2.25% legacy figure
Payment amountEstimated processor feeWhy to verify live checkout
$1,000$22.50Processor fees can change and may show a minimum.
$5,000$112.50A free eCheck may be cheaper if timing allows.
$10,000$225.00Large payments should compare eCheck, ACH, wire and mail rules.
Fee conflict guidance: older county PDFs and legacy pages show different historical card-fee language. Treat the live checkout and current ATC payment page as the controlling source before you authorize payment.
Mail and postmark

San Bernardino County Tax Collector mailing address and postmark rules

San Bernardino County public notices commonly tell taxpayers to mail payments to the Tax Collector at 268 West Hospitality Lane, First Floor, San Bernardino. Some county updates show different ZIP endings, so use the exact address on the current bill or official payment page.

Payee

Make check or money order payable to SBC Tax Collector when using the county tax-payment mailing route.

Include identifiers

Include the bill stub when available. If not, write the APN, bill number, tax year and installment clearly on the payment.

Manual postmark

Near a deadline, go inside a USPS counter and request a manual postmark on or before the delinquency date.

Mailing trap: dropping an envelope in a collection box does not always create a same-day postmark. County guidance says a payment received after the deadline without a timely postmark is late.
California tax calendar

San Bernardino County property tax due dates and delinquency checkpoints

Common secured property-tax timing
DateMeaningAction
October / by November 1Secured tax bills are generally mailed in the fall.Search the account if the bill does not arrive.
November 1First secured installment is due.Prepare payment before the December delinquency cutoff.
December 10First installment generally becomes delinquent after the cutoff.Pay online before the cutoff or mail early with a valid USPS postmark.
February 1Second secured installment is due.Confirm the first installment posted before paying the second.
April 10Second installment generally becomes delinquent after the cutoff.Expect a 10% penalty plus $10 cost if late.
June 30 / July 1Unpaid secured taxes can move toward tax-default status after fiscal-year close.Request a live redemption payoff before assuming an old balance is correct.
Not every bill follows this calendar: supplemental, unsecured, escape, mobile-home, business property and defaulted-tax notices can use dates printed on the notice. Use the bill in front of you.
Penalty warning

Late San Bernardino County property taxes, penalties and defaulted balances

County guidance says property tax payments must be received or postmarked by the delinquency date to avoid penalties. A late first installment adds a 10% penalty; a late second installment adds a 10% penalty plus a $10 fee.

First installment late

Expect a 10% penalty after the delinquency cutoff unless a valid relief or correction applies.

Second installment late

Expect a 10% penalty plus the statutory $10 cost after the delinquency cutoff.

Defaulted account

Defaulted balances can include monthly penalties, redemption fees, costs and later tax years.

Payoff script: “Please give me the amount due through [date] for APN [13 digits], tax year [year], bill number [number], and tell me whether it includes penalties, fees, redemption charges or tax-sale costs.”
Partial payment

Partial payments: useful, but not the same as a payment plan

The newer ATC payment pages advertise partial-payment options. That can help reduce a balance, but it does not automatically erase penalties, stop a deadline or create a formal installment agreement.

Use partial payment when

You cannot pay the full balance and want to reduce the unpaid amount before the next deadline.

Confirm allocation

Ask which bill, year, installment or defaulted balance receives the payment before submitting.

Watch remaining balance

The unpaid amount may still become delinquent or continue adding statutory charges.

Do not assume relief: a partial payment is not a penalty waiver. If you need cancellation of a penalty, use the official penalty-waiver route and keep paying attention to deadlines.
Receipt and posting

How to verify payment history or fix a missing San Bernardino County tax payment

Collect proof first. Find the confirmation number, APN, bill number, payment date, amount and payment method.
Check the county history tool. Use the official account search or payment-history route before calling.
Compare bank/card records. A bank debit does not always prove the county posted it to the correct APN.
Call before paying again. If the payment may have posted to the wrong account, ask the Tax Collector to research it before submitting a duplicate payment.
Request the updated amount if returned. A returned payment after a deadline can change the amount due.
Escrow tip: if a lender or escrow company says it paid, ask for the APN, tax year, amount, check number, wire trace or electronic payment confirmation. Do not rely only on a verbal promise.
Correct department

Tax Collector vs Assessor: who fixes San Bernardino County property-tax problems?

The Tax Collector collects bills and posts payments. The Assessor-Recorder-County Clerk maintains assessment records, ownership data, exemptions and mailing-address changes that feed the tax bill.

New homeowners

New owner, supplemental bill or missing tax bill after buying property

Annual bill has old owner

Property taxes follow the assessment and roll process. Verify APN and amount instead of waiting for the name to change.

Supplemental bill may arrive separately

A purchase or new construction can trigger a supplemental assessment. It may not be paid by the mortgage impound account.

Mailing address matters

The Assessor says mailing-address changes must be requested in writing by the owner of record or authorized agent.

  • Track the APN, not only the owner name.
  • Ask your lender whether escrow covers supplemental bills.
  • Use the Tax Collector for estimated bills and payment status.
  • Use the Assessor for mailing-address and ownership-record corrections.
  • Do not ignore a bill because the name or mailing address is not yet updated.
Appeal route

Assessment appeals do not replace paying the tax bill

If your issue is property value, the Clerk of the Board handles the assessment-appeals process and the Assessor handles valuation questions. Filing an appeal does not remove the need to pay property taxes on time.

Value question

Start with the Assessor for informal review and comparable-property questions.

Formal appeal

The Clerk of the Board administers assessment appeal applications and hearings.

Payment responsibility

Keep paying the bill or confirm official written instructions. A pending appeal does not automatically pause penalties.

Mobile homes and unsecured property

Mobile-home tax clearance, unsecured bills, boats and aircraft

Not every San Bernardino County tax bill is a standard secured real-estate bill. Unsecured property can include business property, boats, aircraft, manufactured homes and owner-based assessments.

Mobile-home transfer

Outstanding taxes should be resolved before transfer. The county provides a tax-clearance request route.

Unsecured bill

Use the unsecured property number or property ID printed on the bill. Do not force a real-property APN into the wrong field.

Payment method caution

Some mobile-home clearance situations may require certified funds, cashier’s check, money order, escrow check or cash. Verify before visiting.

Auction caution

San Bernardino County tax-defaulted property auction checks

Tax-sale searches bring a lot of low-quality copied lists. Use the county Tax Collector or county-named auction platform before registering, wiring money or researching a parcel.

Start at the county Tax Collector source. Do not start from a private lead list or old PDF copy.
Confirm the sale date and sale number. Older county pages may describe completed sales. A historical sale date is not the next sale.
Read the current terms. Deposit, registration cutoff, settlement deadline, allowed final-payment methods and fees can change.
Research the parcel independently. Check APN, access, zoning, liens, easements, occupancy, legal description, environmental risk and title issues.
Recheck before bidding. A parcel can be redeemed, removed, corrected or withdrawn before sale.
Do not trespass: a tax-sale listing does not give permission to enter private or occupied property. Research from public records and lawful public locations.
Scam prevention

Before you submit payment, check these San Bernardino County scam signals

Safe signals
  • You opened the official county domain yourself.
  • The APN, bill year and installment match your bill.
  • The fee is visible before authorization.
  • You can save a receipt or confirmation.
  • Wire instructions were confirmed by calling the published county number.

  • Unexpected phone call demanding immediate tax payment.
  • Email or text asking for card or bank details.
  • Payment link that is not county-linked.
  • Threats, pressure or “today only” language.
  • Wire instructions copied from a forwarded email.
Best move: close the message, open the official ATC website manually, or call 909-387-8308. Do not reply to the suspicious sender.

No. TaxCollectors.org is an independent guide. Complete payments, account searches, wire instructions, assessment corrections, appeals and tax-sale actions only through official San Bernardino County ATC, Assessor, Clerk of the Board or county-linked systems.

Independent guide notice: TaxCollectors.org is not the San Bernardino County Auditor-Controller/Treasurer/Tax Collector, Assessor-Recorder-County Clerk, Clerk of the Board, payment processor, auction platform, tax adviser or law firm. Property-tax balances, office hours, payment fees, payment methods, postmark rules, assessment appeal deadlines, tax-sale dates, auction terms and mailing addresses can change. Verify directly with the official county source before paying, mailing a check, wiring money, visiting an office, filing an appeal or relying on a deadline.
