The California Constitution and the Revenue & Taxation Code state that all property is taxable, including business property, unless it is specifically exempt by law.  Examples of taxable business property are:

  • Supplies
  • Machinery & Equipment
  • Tools
  • Office Furniture & Equipment
  • Computer Hardware & Operating Systems
  • Buildings/Fixtures/Land Improvements
  • Leasehold Improvements
  • Property Leased to Others
  • Construction in Progress

Most business property is assessed by the Cost Approach. The Replacement Cost New (RCN) is determined by indexing the historical cost, and then an allowance for depreciation is applied.

The Real Property Division of the Assessor’s Office assesses the land and real property structures to the land owner.  The Business/Personal Property Division assesses the remaining taxable business property (above) to the owner of the business.

Every year in January, identified businesses receive a request from the Assessor to file the Business Property Statement (form 571-L) or the Agricultural Property Statement (form 571-A) for business property owned as of 12:01 a.m., January 1st (lien date) of that year. The property statement should be completed in its entirety, signed, and returned to the Assessor by April 1st. All businesses that receive a property statement are to file; Businesses owning $100,000 (cost) or more of taxable personal property are required to file a property statement even if the Assessor does not send one and will be  penalized if they do not file.

Specific instructions are provided with the property statement. The Assessor requests general information regarding the business ownership, type of business, business location, and mailing address, etc. In addition, the owner is required to report business property by acquisition cost, year acquired, and category.

Please contact the Assessor's office if you have not received your property statement by the end of January or if you would like to file electronically.  The following link can be used to electronically file your property statement after you have been assigned your Business Identification Number (BIN) by the Assessor:

Electronic Filing of Business Property Statements **E-Filing will be available by mid January. This link is active for your use.

E-Filing is available for most, but not all, businesses. If available, property statements include necessary information to E-File on the form. If you chose to E-file the printed statement does not need to be returned.

571-L with 571-D(supplemental schedule).

In addition to the Business Property Statement, some businesses will file:

Financial Corporations 571-LA


If a business fails to file the Business or Agricultural Property Statement, or if it is filed late (postmarked after May 7th) (exception: If May 7 falls on a Saturday, Sunday, or legal holiday, a property statement that is mailed and postmarked on the next business day shall be deemed to have been filed between the lien date and 5 p.m. on May 7.), a 10% penalty will be applied as required by Revenue & Taxation Code Section 463.
Willful concealment of tangible personal property may result in a 25% penalty (R & T Sec 504). Fraud causing the escape of taxable tangible property may result in a penalty of 75% (R & T Sec 503).

All businesses are subject to audit in order to verify the accuracy of the reported information and the correctness of the Assessor's work in valuing. Some audits are required by the State Board of Equalization ("mandatory") per R & T Code Section 469. Any other audit is considered a "non-mandatory" audit. Information requested by the Assessor per Sections 441 or 442 of the Revenue & Taxation Code must be provided by the Assessee.
