Form BOE-100-B, Statement of Change in Control and Ownership of Legal Entities, is used by the BOE to obtain information to determine whether a transfer of interest in a legal entity has triggered a change in control or ownership that results in the reassessment of the California real property owned by the entity, and whether an exclusion from change in ownership applies. Failure to file in either circumstance noted above will result in application of penalty pursuant to Revenue and Taxation Code section 482(b).

Whenever there is a change in ownership or a change in control of a legal entity and the legal entity owned an interest in California real property as of that date, the person or legal entity acquiring ownership control or the legal entity that has undergone a change in ownership must file a statement with the Board. (See Revenue and Taxation Code sections 480.1 and 480.2.)
When an entity is requested by the BOE to file regardless of whether or not a change in control or ownership of the legal entity has occurred or whether the legal entity owned an interest in real property.

The acquiring person or legal entity is required to file form BOE-100-B within 90 days of the change in control or the legal entity that has undergone a change in ownership must file. However, any person or legal entity that receives a form BOE-100-B must complete and file the BOE-100-B with the BOE. Note: If a written request to file is made by the BOE, form BOE-100-B must be filed within 90 days, regardless of whether a change in control or ownership of the legal entity has occurred. (See Revenue and Taxation Code sections 480.1 and 480.2.)
