Revenue and Taxation Code section 18621

Except as otherwise provided by the Franchise Tax Board and in Section 18621.5, any return, declaration, statement, or other document required to be made under any provision of Part 10 (commencing with Section 17001), Part 11 (commencing with Section 23001), this part, or any applicable regulation shall contain, or be verified by, a written declaration that it is made under the penalties of perjury. Those returns, and all other returns, declarations, statements, or other documents or copies thereof required, shall be in any form as the Franchise Tax Board may from time to time prescribe, including, but not limited to, on paper, on magnetic media pursuant to Section 19524, or by electronic technology or electronic imaging technology pursuant to Section 18621.5, and shall be filed with the Franchise Tax Board. The Franchise Tax Board shall prepare blank forms for the returns, 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 taxpayer from making any return, declaration, statement, or other document required.
