Unemployment Insurance Code section 13058

Except as otherwise provided by the department, any return, report, statement, or other document required to be made under any provision of this division or authorized regulations shall contain, or be verified by, a written declaration that it is made under the penalty of perjury. The returns, reports, and all other returns, reports, statements, or other documents or copies thereof required by this division, shall be in the form as the department may from time to time prescribe, and shall be filed with the department. The department shall prepare blank forms for the returns, reports, declarations, statements, or other documents and shall distribute them throughout the state and furnish them upon application. Failure to receive or secure the form does not relieve any employer or person from making any return, report, statement, or other document required.
