How to Pay San Bernardino County Property Tax Online
The safest path is to start from the official ATC website, search your property tax account, review the bill and payment status, then complete payment only through the official county-supported payment flow.
Start at the official ATC site
Use SBCountyATC.gov or the official online tax services link. Avoid search ads, text-message payment links and unofficial “pay county tax” pages.
Search your property tax bill
Use your parcel number, account number, bill number or other official bill details. Keep your bill nearby so you do not select the wrong account.
Review amount, installment and delinquent date
Confirm whether you are paying the first installment, second installment, an unsecured bill, a supplemental bill, a delinquent bill or a partial payment.
Choose the payment method
Review official fees, processing timing and confirmation details before submitting. For large or unusual payments, contact ATC first.
Save confirmation
Save or print the confirmation number and check the official payment-history route later if you need proof that the payment posted.
Payment Options: Online, Phone, Mail or In Person
Choose the payment method based on deadline risk, confirmation needs and whether you are close to a delinquency date. The closer you are to a deadline, the more careful you should be with mail timing and proof of payment.
Online

Useful for account questions or if you need help with the correct bill, payment status, tax sale questions or official payment instructions.

San Bernardino County Property Tax Deadlines
California property tax dates are strict, and penalties can be expensive. Always compare this planning table with your actual bill and the official ATC important-dates page.
| Tax type / event | Common date | What it means | Planning warning |
|---|---|---|---|
| Unsecured tax bills mailed | July | Unsecured bills are generally mailed in July. | Do not ignore an unsecured bill because it is separate from your mortgage escrow or regular secured bill. |
| Unsecured taxes due | August 1 | The unsecured bill becomes due. | Use the official bill and ATC portal to confirm final balance and deadline. |
| Unsecured payment deadline | August 31 | County materials state a 10% penalty can be added if not paid timely, plus collection/default costs where applicable. | Pay early or verify postmark rules before mailing. |
| Secured annual bills mailed | October | Original secured property tax bills are mailed. | If you do not receive a bill, contact the Tax Collector; not receiving a bill does not remove the payment obligation. |
| First secured installment due | November 1 | The first installment becomes due. | The key penalty deadline is usually December 10. |
| First secured installment delinquent | After December 10 | A 10% penalty is generally added if not paid on time. | If the date falls on a weekend or holiday, check the official next-business-day rule. |
| Second secured installment due | February 1 | The second installment becomes due. | Do not wait for April if you need mail time or account help. |
| Second secured installment delinquent | After April 10 | A 10% penalty plus a cost can apply if not paid on time. | Pay online or get a clear postmark if mailing close to the deadline. |
| Delinquent secured accounts | June 30 | Unpaid secured accounts can transfer to the delinquent tax roll with additional penalties and fees. | Contact ATC before this point if you are behind or confused about bill status. |
Mail and Postmark Warning for Deadline-Sensitive Payments
Mailing close to a tax deadline is risky because a payment may be considered late if it is received after the deadline without a valid timely postmark. San Bernardino County has specifically advised residents to plan ahead when mailing deadline-sensitive county documents.
Mail early
Do not drop a tax payment in the mail at the last minute and assume it will receive the postmark you need. Processing and pickup timing can matter.
Ask for a manual postmark
If mailing near a deadline, take the envelope to a USPS counter and request a manual postmark on or before the deadline.
Keep proof
Keep copies of the bill, check or money order details, tracking, receipt and any official confirmation until your payment posts.
Partial Payment Option
San Bernardino County ATC has announced a partial-payment option for secured property taxes. This can help some taxpayers make smaller payments through the year, but it does not automatically remove deadlines, penalties or costs. Read the official partial-payment page before using it.
What it helps with
It may help property owners spread payment activity instead of waiting for one large installment payment.
What it does not do
It does not mean your bill cannot become delinquent. Confirm how much must be paid by each official deadline.
When to call
Call ATC if your account is delinquent, defaulted, under tax sale risk, held by an escrow company, or has multiple bill types.
Before You Search or Pay: Keep These Details Ready
Having the correct bill details prevents wrong-account searches and reduces the risk of paying the wrong installment.
- Parcel number or account number: use the number shown on your official tax bill or property records.
- Bill number: useful when there are multiple bills, supplemental bills or unsecured bills.
- Installment: confirm whether you are paying the first installment, second installment, both installments or a delinquent balance.
- Owner or property address: use only to verify the account, not as the only identifier.
- Payment method: review official card, e-check, phone, mail or in-person rules before submitting.
- Confirmation proof: save receipts and online confirmations until your county account shows the payment.
Penalty Waiver, Late Payments and Delinquent Taxes
If your San Bernardino County property tax is late, do not rely on a general article to decide whether a penalty can be removed. Use the official ATC forms or contact route and provide the documentation requested by the county.
Penalty waiver request
ATC has an official penalty waiver request route. Read the county’s requirements before assuming your situation qualifies.
Late balance
Late bills may include penalties, costs, redemption fees or monthly additions depending on tax type and delinquency status.
No guarantee
TaxCollectors.org cannot promise penalty removal, deadline extensions, payment posting or tax sale delay. The county controls account decisions.
Tax Sales, Excess Proceeds and Special Tax Collector Services
The Tax Collector division also handles tax sale and related services. If your search is about a defaulted property, auction, excess proceeds, mobile home tax clearance or transient occupancy tax, use the official ATC section rather than the regular property-tax payment page alone.
Property tax
Use for secured, unsecured, supplemental and delinquent property tax bill questions.
Tax sale
Use official tax sale notices and ATC pages for auction dates, requirements and excess proceeds information.
Mobile home tax clearance
Use the county’s tax collector route for mobile home tax clearance certificate questions.
Transient occupancy tax
Use official ATC resources for TOT-related tax collector services, not the ordinary homeowner bill search.
San Bernardino County Property Tax Scam Warning
Property tax payment scams are a real risk around bill-mailing and deadline periods. Be especially careful with phone calls, emails, text messages or letters that create pressure, threaten unrelated penalties or push you to use a non-county payment method.
Check the domain
Use SBCountyATC.gov or an official San Bernardino County government page. Do not rely on look-alike domains.
Question unexpected messages
Do not click a tax-payment link from a surprise text, email or social message without verifying through the official county site.
Verify by phone
Call the official Tax Collector number if a notice or caller seems suspicious. Use the number from the official site, not the suspicious message.
Accessibility, Language and Visiting the Office
Before visiting the Tax Collector office, check the official contact page or call for current hours, holiday closures, accessibility needs, language assistance, payment-method limits and document requirements. Do this especially if you are traveling from the High Desert, mountain communities, Morongo Basin or another long-drive area of the county.
Accessibility questions
Ask the county directly about accessible entrance, parking, document drop-off, appointment needs or assistance before visiting.
Online-first planning
Many property tax tasks can begin online. Try the official online portal before making a long in-person trip.
Bring documents
Bring your tax bill, parcel/account number, photo ID if needed, payment method and any county notice related to your question.
