Rev. & Tax. Code, § 4832.1

If the amount of any tax or special assessment is understated on the roll by five dollars ($5) or less due to clerical error of the auditor, the amount by which such tax or special assessment is understated may be canceled by the auditor. After cancellation by the auditor, the amount appearing on the roll shall in each instance be deemed the correct amount of that tax or special assessment for all purposes and upon payment of that amount the tax collector shall show the tax or special assessment as paid in full. The auditor need not note the cancellation on the roll. Whenever a portion of the rate of any tax or special assessment is canceled in the manner provided by this section, written consent of any city attorney shall not be required.
