Rev. & Tax. Code, § 7073

(a) This article shall apply to any taxpayer who, during the amnesty period specified in Section 7071, meets all of the following:

(1) Is eligible to participate in the tax amnesty program.

(2) Files a completed amnesty application with the board, signed under penalty of perjury, to participate in the tax amnesty program.

(3) Within 60 days after the conclusion of the tax amnesty period, does all of the following:

(A) Files completed tax returns for all tax reporting periods for which he or she has not previously filed a tax return and files completed amended returns for all tax reporting periods for which he or she underreported his or her tax liability.

(B) Pays in full the taxes and interest due for all periods for which amnesty is requested, or applies for an installment agreement under subdivision (b).

(C) For taxpayers who have not paid in full any tax liabilities due and payable for tax reporting periods beginning before January 1, 2003, pays in full the taxes and interest due for each period for that portion of the proposed determination for each period for which amnesty is requested or applies for an installment payment agreement under subdivision (b).

(4) In the case of any taxpayer that has filed for bankruptcy protection under Title 11 of the United States Code, submits an order from a Federal Bankruptcy Court allowing the taxpayer to participate in the amnesty program.

(b) The board may enter into an installment payment agreement in lieu of the complete payment required under subparagraph (B) of paragraph (3) of subdivision (a), but only if final payment under the terms of that installment payment agreement is due and is paid no later than June 30, 2006. The installment payment agreement shall include interest on the outstanding amount due at the rate prescribed by law. Failure by the taxpayer to fully comply with the terms of the installment payment agreement shall render the waiver of penalties null and void, unless the board determines that the failure was due to reasonable causes, and the total amount of tax, interest, and all penalties shall be immediately due and payable.

(c) If, subsequent to the amnesty period specified in Section 7071, the board issues a deficiency determination upon a return filed pursuant to subdivision (a), or upon any other nonreporting or underreporting of tax liability by any person who could have otherwise been eligible for amnesty, the board shall impose penalties at a rate that is double the rate of penalties described in law and criminal action may be brought under this part only with respect to the difference between the amount shown on that return and the correct amount of tax, or the amount of unreported or underreported tax, whichever the case may be. This action may not invalidate any waivers granted under Section 7072.

(d) If the board issues a deficiency determination under conditions described in subdivision (c), the board may issue that deficiency determination within 10 years from the last day of the calendar month following the quarterly period for which the amount is proposed to be determined.

(e) The application required under paragraph (2) of subdivision (a) shall be in the form and manner specified by the board, but in no case shall a mere payment of any taxes and interest due, in whole or in part, for any period otherwise eligible for amnesty under this part, be deemed to constitute an acceptable amnesty application under this part. For purposes of the preceding sentence, the application of a refund from one period to offset a tax liability for another period otherwise eligible for amnesty shall not be allowed without the filing of an amnesty application under this part.
