Filing Form 571L Business Property Statement
- Businesses are required by law to file an annual Business Property Statement (BPS) if their aggregate cost of business personal property is $100,000 or greater, or if the Assessor requests the information in writing.
- Separate filings are required for each business location.
- Statements are due April 1st.
- A 10% penalty will be applied if a BPS is received after June 1, 2020.
- Business Property Statements are confidential documents and are held secret by the Assessor.
Filing can be done by mailing us the paper statement or by filing electronically. Most business owners will be able to take full advantage of e-filing. Unfortunately at this time, owners of apartments, aircraft or commercial agricultural property will need to file with a paper form which will be mailed to you. However for most businesses, filing on-line is the "green" alternative that saves time and maximizes efficiency for both you and the Assessor's Office.
e-Filing Information
Electronic filing of the Business Property Statement uses a web-based application that will allow users to view, modify, and submit BPS filings on-line.
Business owners in California may e-file by using SDR or e-SDR. SDR (Standard Data Record) is designed for large businesses with multiple locations in one or more California counties. SDR simplifies the process of filing annual statements by bundling a group of statements into a single file. The SDR system only accepts statements that are filed electronically in the approved XML format. Special programming and/or software is required to create SDR files. SDR is not generally recommended for the small business owner.
e-SDR is the system that was designed with the small business owner in mind. Statements are filed through an interactive system with instructions and no special software or programming is required. e-SDR is recommended for businesses with fewer than five locations, as each location requires a separate statement. The process to file electronically is secure and fast. When you or your authorized representative has completed the form you'll receive an immediate, on-line confirmation of your filing. In addition, you'll have the ability to print a copy for your records.
