If an income-expense form, any information sought under the form,
or records or documents sought to completely and accurately inform the Deputy Chief Financial Officer about the income or economic benefits of the income-producing property are not submitted in the time provided for by this chapter, and it is shown to the Deputy Chief Financial Officer's satisfaction that the failure to provide the form, information, record, or document was due to reasonable cause, the Deputy Chief Financial Officer shall not add the penalty described in § 330 to the affected taxpayer's real property tax bill for the next ensuing tax year.
For the purposes of § 331.1, the phrase "reasonable cause" shall be construed to mean the following:
A waiver of penalty and interest for failure to submit the required income and expense or related information or documents, in accordance with the provisions of this chapter, shall not be granted unless the facts and circumstances to justify the failure have been set forth in writing by the affected taxpayer and approved by the Director, Real Property Tax Administration.
A request for waiver of penalty and interest under this section shall be submitted to the Deputy Chief Financial Officer on or before November 1st following the due date for submission of the income and expense form, as provided in § 332; provided that the request for waiver of penalty concerning the income-expense form due on April 1, 2009 may be submitted to the Deputy Chief Financial Officer through April 1, 2009.
In addition to the submission of a request for waiver of penalty and interest as provided for § 331.4, the filing of an accurately completed income-expense form shall be a prerequisite to obtaining a waiver of penalty and interest.
