Rate Breakdown

Property taxes in San Bernardino County are calculated by multiplying the assessed value (minus exemptions) by the total local millage rate.

How Property Tax Works in San Bernardino County

In San Bernardino County, property taxes are calculated through a two‑step process: assessment and levy. The County Assessor’s Office evaluates each parcel twice a year—on January 1st and July 1st—to determine its current market value. A full disclosure report is available online if you wish to review the assessment details.

Once the assessment is finalized, the tax amount is set by the county’s millage rate. A mill is one-thousandth of a dollar. San Bernardino County’s basic millage rate is approximately 2.908 mills, but additional local levies—such as school bonds, library taxes, or special district assessments—can add up to several extra mills. The final annual property tax is the assessed value multiplied by the total millage rate and then divided by 1,000. For example, a property assessed at $600,000 with a 3.5 mill rate would owe roughly $2,100 per year.

Available Exemptions

California offers several exemptions that can significantly reduce your taxable base. In San Bernardino County, the most common ones include:

• Homestead Exemption: A property owner can receive a $10,000 reduction on the assessed value if the property is their primary residence.
• Senior Citizen Exemption: Eligible seniors (age 55 or older) may claim an additional $7,500 exemption, provided they own and occupy the home and their combined income does not exceed the county’s threshold, which is adjusted annually.
• Disability Exemption: If you or a spouse is a California disabled veteran or a non‑veteran with a disability becoming a recipient of SSI or SSDI, a $25,000 exemption on the assessed value can be applied.
• Veteran Exemptions: A California Disabled Veteran may qualify for a $25,000 exemption; for non‑disabled veterans, the exemption is typically $20,000. The most‑recent California Legislature legislation allows a property tax deferral program for qualifying veterans beyond the straight exemption.

To apply, you must file the appropriate exemption form with the County Assessor by the filing deadline (usually May 1st). It’s important to keep the exemptions updated annually to reflect changes in ownership or eligibility.

Payment Schedule & Deadlines

San Bernardino County collects property taxes in two installments. The first is due on or before June 30th of the tax year, and the second is due on or before November 30th. If you choose to pay one payment, it must be made by the June deadline; however, the late payment penalty can bring the partial payment tax up to a 130‑day delinquency status.

The county offers an optional payment plan—called the “K.O.P. Plan”—which allows property owners to pay their taxes in twelve equal monthly installments. Enrollment is completed online and requires a one‑time fee. Fees incurred after enrollment are automatically applied to the next installment.

Late payments incur a 1.2% per‑month interest charge plus a $250 late fee if the payment is more than 40 days overdue. If the property remains unpaid after one year, the county can initiate a tax lien sale, potentially resulting in loss of the property. Thus, staying current on dues is essential to avoid costly penalties and preserve property ownership.

Appealing Your Assessment

If you believe your property has been assessed at too high a value, you can file an appeal with the San Bernardino County Assessor’s Office. The appeal process typically involves the following steps:

• Initial Review: Submit a written appeal form, along with any supporting documentation (e.g., recent sales of comparable properties, appraisal reports). The deadline for filing is usually within 30 days of the assessment notification.
• Pre‑hearing Consultation: The assessor will schedule a conference to discuss your concerns and may adjust the assessment if new evidence is compelling.
• Formal Hearing: If the pre‑hearing resolution fails, the case proceeds to a formal hearing before the County Assessor’s Appeal Board. The board will review the evidence and decide whether to increase, decrease, or maintain the current assessment.
• Final Decision: The hearing outcome is final unless the Superior Court intervenes. It’s recommended to consult an attorney or a property tax consultant if the case is complex.

Appeals are cost‑effective because the assessor covers the administrative expenses, and successful appeals can result in significant tax savings.
