Whether you’re a first-time homebuyer in Rancho Cucamonga or a long-time resident of Redlands, understanding property taxes in San Bernardino County is essential. These taxes help fund local schools, fire protection, and public infrastructure, key elements that keep communities thriving across the Inland Empire.
This guide breaks down everything you need to know about San Bernardino County property taxes so you can stay informed and confidently manage your responsibilities as a homeowner.
What Exactly Are Property Taxes?
Property taxes are annual charges imposed by local governments on real estate owners. These taxes fund vital community services like public education, police and fire departments, road maintenance, and libraries.
In San Bernardino County, your property tax bill includes contributions to several taxing agencies, not just the county itself. Each portion of your payment helps maintain the essential services and infrastructure that make San Bernardino a desirable place to live and own property.
How Much Is Property Tax in San Bernardino County?
In San Bernardino County, the County Assessor’s Office determines your property’s assessed value, which is the foundation of your property tax calculation.
Under California’s Proposition 13, the base property tax rate is 1% of the property’s assessed value, plus any voter-approved local assessments and bonds. The exact total rate varies by neighborhood and the local measures in effect.
Your assessed value is usually based on the property’s purchase price and can increase by no more than 2% per year, unless ownership changes or substantial improvements are made.
When Are Property Taxes Due in San Bernardino County?
Property taxes in San Bernardino County are paid in two installments each fiscal year:
- First installment: Due November 1, delinquent after December 10
- Second installment: Due February 1, delinquent after April 10
Missing these deadlines can result in penalties, so it’s best to pay early or set reminders to stay on track. If a delinquency date falls on a weekend or holiday, the deadline extends to the next business day.
When Will You Receive Your Property Tax Bill?
San Bernardino County mails secured property tax bills in early October each year.
If you don’t receive your bill, you’re still responsible for timely payment. You can access your property tax information, check balances, or verify due dates online through the San Bernardino County Treasurer-Tax Collector’s website.
What Happens If You Miss the San Bernardino Property Tax Due Date?
If a payment is not received by the delinquency date, the county applies a 10% penalty to the unpaid installment.
If taxes remain unpaid after June 30, the property becomes tax-defaulted, and additional penalties and fees begin to accrue. Continued delinquency can result in the property becoming subject to the tax collector’s power of sale after a statutory period if not redeemed.
Paying on time helps you avoid costly penalties and protects your property from potential legal action.

What About Special and Supplemental Taxes?
Aside from the annual property taxes, you might also encounter special or supplemental taxes These are levied for specific purposes, such as funding local infrastructure projects or schools. Supplemental taxes can arise from reassessment of your property’s value due to changes in ownership (for example, if you purchase a new home) or because of new construction or major improvements. Understanding these additional charges is crucial for a full view of your total tax responsibility.
How Are Supplemental Taxes Calculated in San Bernardino County?
In San Bernardino, when a property undergoes a reassessment due to a change in ownership, major improvements, or new construction, the County Assessor calculates the new assessed value. The difference between the old and new assessed values is then used to calculate the supplemental tax, which is prorated based on the number of months remaining in the fiscal year from the date of ownership change or project completion.
