About the Los Angeles County Office of the Assessor
The collection reflects several distinct property-tax topics. Exemption claims include forms for homeowners, veterans, religious organizations, schools, and qualifying housing. Some housing-related documents are supplemental affidavits or income worksheets, while others are initial or annual exemption claims; they serve different purposes and should not be treated as interchangeable.
Other forms address ownership changes and changes in assessed value. The catalog includes ownership statements for real property and oil and gas property, as well as claims involving transfers of a base-year value to a replacement residence. Separate applications concern assessment exclusions for certain types of new construction, and a decline-in-value application addresses a different assessment question. The titles indicate the topics, but do not establish which form applies to an individual property or situation.
The business and specialized property documents include property statements, reports, and supplemental schedules for areas such as aircraft, vessels, utilities, oil and gas, and industry-specific business property. These forms are distinct from homeowner exemption and ownership-change documents. The forms currently listed on this page are a selection of published forms associated with the Los Angeles County Office of the Assessor, not necessarily every document the office issues. Check the issuing agency’s current instructions for applicable versions, eligibility, supporting documents, deadlines, and submission methods.
