An Important Message From The Assessor

I want to welcome you to the Imperial County Assessors’ Website. We have modified this site to make it easier to access public information and to use the online options that are now available for the property and business owners of Imperial County.  Providing online services is our effort to improve how we serve taxpayers in keeping with the Imperial County 2020 Strategic Plan.

All business property filers can now electronically file (e-file) their property statements directly with the Assessor Office using either the Megabyte Systems Online Business Property Filing (OBPF) network or the California Assessors Association Shared Services Standard Data Record (SDR & e-SDR) electronic-filing network.

Business property filers who annually file either an Agricultural Property Statement, Form 571-F or a Business Property Statement, Form 571-L received a letter that contains a Business Identification Number (BIN#) which is a unique, private and secure access code that each individual business can use to e-file their annual business property statement. Click on to access the OBPF network.

Financial institutions and insurance companies that file Form 571-LA and multi-residential property owners who file Form 571-R also received a letter that contains a Business Identification Number (BIN#).  These businesses can e-file by clicking on to access the e-SDR network and view the e-file instructions.

Businesses with multiple locations (recommended for 20 or more) in one or more California counties have the option of filing electronically using the California Assessors Association Standard Data Record (SDR) network.  To access the SDR e-file network, go to:  This network is designed for businesses that file multiple statements at one time and it has specific programing and software requirements.

 There are fillable PDF Property Statement forms available on the Assessors’ website.  To access these forms, click on Forms/Personal Property.  Once on the forms page you will click on the specific form link which will take you to the California Assessors Association e-forms website where you will have access to the most current version of a California Board of Equalization approved form.  Fillable PDF forms can be completed online, printed and either mailed or delivered to the Assessor’s Office.

The filing dates for both e-filers and paper filers are as follows:

April 2, 2018:Business property statements are due.

May 7, 2018: Final day to file business property statements without a 10% late penalty.

May 31, 2018: Last day to amend a timely filed business property statement.

For questions related to property statements or for assistance with electronic filing, please call the Assessors’ Business Property information telephone line at (442) 265-8805 or e-mail questions or request to
