If you have recently purchased a home in San Bernardino County, we would like to congratulate you on your new purchase.

We have attempted to give you all of the information you need in one easy to use location.

Whether you have recently purchased a home in San Bernardino County, or are considering purchasing a home in San Bernardino County, the information on this website can be a valuable resource for you.

What to expect from your Treasurer - Tax Collector when you buy a new home:

  • New Assessed Property Value - When a property changes ownership, a new assessed value will be used in determining your property taxes.  This will generally be based on the amount you paid for your property.  If you have any questions regarding the New Assessed Property Value, please contact the Assessor by clicking here or at (909) 387 - 8307.
    You may estimate the amount of your new taxes on this website, please click Estimate Your New Tax Bill.

  • Supplemental Tax Bills - Supplemental tax bill(s) are one-time tax bill(s) which occurs when there is a change of ownership on a property.  The amount of the supplemental tax bill(s) is determined by taking the difference between your new assessed property value and the previous assessed property value.
    Mortgage companies do not usually pay the supplemental tax bill(s).  They are the responsibility of the new property owner.
    You will normally receive your new supplemental tax bill(s) within 6 to 9 months of purchasing the property.
    The supplemental tax bill(s) will be pro-rated from the date of purchase through July 1st of that year.
    (Depending on when you purchase your property, and when the property is re-assessed, you may receive 2 supplemental tax bills).

  • Homeowners Exemption - Property that is owned and occupied as your principal place of residence as of the lien date (January 1st) may qualify for an exemption of $7,000 of assessed value.  The Assessor will send you a Homeowner Exemption form in 2 to 3 months from your purchase date. Should you not receive a Homeowner Exemption form after 4 months please contact the Assessor's office.

Differences between the Treasurer - Tax Collector and the Assessor

There is frequently some confusion about the different roles of the Treasurer-Tax Collector and the Assessor.   They are two different elected officials serving the public in different roles.

  • The Assessor is the elected official who is responsible for the assessment of all property within the County.  The assessment of property (or the valuation of property) is one of the components that determine the amount of taxes that are owed.  The Assessor may be contacted at 909-387-8307 or their website may be viewed by clicking here.
  • Some reasons you may want to contact the Assessor are:
    • You think your property may have been assessed at too high of a value.
    • To change the mailing address for your tax bills.
    • To get information on the Homeowner's exemption or other programs that can help to lower your taxes.
  • The Treasurer-Tax Collector is the elected official who is responsible for the Administration of the County Investment Pool and responsible for the collection of all property tax bills in the County.
