Article 2. Deficiency Determinations of California Revenue And Taxation Code >> Division 2. >> Part 22. >> Chapter 3. >> Article 2.

(a) If the board is dissatisfied with the return or report filed or the amount of tax paid to the state by any taxpayer, or if no return or report has been filed or no payment or payments of the taxes have been made to the state by a taxpayer, the board may compute and determine the amount to be paid, based upon any information available to it. In addition, where the board is authorized to collect a tax for another state agency, the board may issue a notice of determination or similar billing document for collection of the tax. One or more additional determinations may be made of the amount of tax due for one, or for more than one, period. The amount of tax so determined shall bear interest at the modified adjusted rate per month, or fraction thereof, established pursuant to Section 6591.5, from the date the amount of the tax, or any portion thereof, became due and payable until the date of payment. In making a determination, the board may offset overpayments for a period or periods against underpayments for another period or periods and against the interest and penalties on the underpayments.
  (b) If any part of the deficiency for which a determination of an additional amount due is found to have been occasioned by negligence or intentional disregard of this part or authorized regulations, a penalty of 10 percent of the amount of the determination shall be added, plus interest as provided above.
  (c) If any part of the deficiency for which a determination of an additional amount due is found to be occasioned by fraud or an intent to evade this part or authorized regulations, a penalty of 25 percent of the amount of the determination shall be added, plus interest as provided in subdivision (a).
  (d) The board shall give to the taxpayer written notice of its determination. The notice shall be placed in a sealed envelope, with postage paid, addressed to the taxpayer at his or her address as it appears in the records of the board. The giving of notice shall be deemed complete at the time of the deposit of the notice in a United States Post Office, or a mailbox, sub-post office, substation or mail chute, or other facility regularly maintained or provided by the United States Postal Service without extension of time for any reason. In lieu of mailing, a notice may be served personally by delivering to the person to be served, and service shall be deemed complete at the time of delivery. Personal service to a corporation may be made by delivery of a notice to any person designated in the Code of Civil Procedure to be served for the corporation with summons and complaint in a civil action.

(a) Except in the case of fraud, intent to evade this part, authorized rules and regulations, or failure to make a return, every notice of a determination of an additional amount due shall be given within three years after the date when the amount should have been paid or the return was due, or within three years after the return was filed, whichever period expires later. In the case of failure to make a return, the notice of determination shall be mailed within eight years after the date the report or return was due.
  (b) The limitation specified in subdivision (a) shall not apply to a liability for the fee imposed pursuant to Section 25205.5 of the Health and Safety Code which is proposed to be determined with respect to a taxpayer if a notice of determination for the fee imposed pursuant to Section 25205.2 of the Health and Safety Code has been given pursuant to Section 43201 or 43350 for the same period and site, or with respect to a taxpayer that has paid the fee imposed by Section 25205.2 of the Health and Safety Code for the same period and site. The notice of determination with respect to the fee imposed pursuant to Section 25205.5 of the Health and Safety Code shall be given within 90 days from the date of final board action or final judicial action, whichever is later, concerning liability for the fee imposed pursuant to Section 25205.2 of the Health and Safety Code.
  (c) The limitation specified in subdivision (a) shall not apply to a liability for the fee imposed pursuant to Section 25205.2 of the Health and Safety Code which is proposed to be determined with respect to a taxpayer if a notice of determination for the fee imposed pursuant to Section 25205.5 of the Health and Safety Code has been given pursuant to Section 43201 or 43350 for the same period and site, or with respect to a taxpayer that has paid the fee imposed by Section 25205.5 of the Health and Safety Code for the same period and site. The notice of determination with respect to the fee imposed pursuant to Section 25205.2 of the Health and Safety Code shall be given within 90 days from the date of final board action or final judicial action, whichever is later, concerning liability for the fee imposed pursuant to Section 25205.5 of the Health and Safety Code.

In the case of a deficiency arising under this part during the lifetime of a decedent, a notice of deficiency determination shall be mailed within four months after written request therefor, in the form required by the board, by the fiduciary of the estate or trust or by any other person liable for the tax or any portion thereof.

If before the expiration of the time prescribed in Section 43202 for the mailing of a notice of deficiency determination the taxpayer has consented in writing to the mailing of the notice after such time, the notice may be mailed at any time prior to the expiration of the period agreed upon. The period so agreed upon may be extended by subsequent agreements in writing made before the expiration of the period previously agreed upon.
