Cal. Revenue and Taxation Code - RTC § 613. Section 613.

A mistake in the name of the owner or supposed owner of real estate does not render invalid an assessment or any deed to a purchaser at a tax sale. A mistake in the name of an owner or supposed owner of property on the unsecured roll which does not prevent the person from reasonably ascertaining that he or she is the assessee does not render invalid an assessment or any tax sale.

Where the personal property on the secured roll of a person not required to file a property statement pursuant to Section 441 is assessed in excess of one thousand dollars ($1,000), excluding household furnishings and personal effects, the assessor, on or before July 15, may notify the assessee of the full value, the assessed value of such property, and the ratio used in the manner prescribed by Sections 619 and 619.1. If the assessee does not receive notice of the assessment pursuant to this section, the assessee may pay taxes based upon such assessment under protest and obtain equalization of the assessment in the same manner as set forth in Section 620.

Cal. Revenue and Taxation Code - RTC § 620. Section 620.

If the assessor does not send a notice pursuant to Section 619 or 621 to an assessee whose property was not on the prior year’s secured roll, or to an assessee of real property on the local secured roll whose property’s full value has increased, then the assessee may pay taxes under protest. If payments are made in installments, the protest need not be repeated with the second installment. Protests shall be made by filing with the clerk of the county board, a petition for assessment reduction on the form prescribed by the county board. The county board may, after receipt of the petition for assessment reduction, hold a public hearing at the next regular board meeting, notice of time and place of which shall be sent to the person paying the tax under protest at the address stated in the protest or if no such address is stated, then to the address of the assessee according to the last equalized assessment roll. If the taxes are so paid and the assessee has not previously applied for a reduction of the assessment, the county board, at its next annual meeting as an equalization board, shall equalize the assessment in the manner prescribed by Article 1 (commencing with Section 1601) of Chapter 1 of Part 3 of this division. The tax rate fixed for property on the roll on which the property so equalized appears at the time of its original assessment shall be applied to the amount of the equalized assessment, determined in accordance with the preceding paragraph. In the event that the resulting figure is less than the tax computed, the taxpayer shall be liable for tax only for the lesser amount, and the difference shall be canceled. If the taxpayer has already paid the tax previously computed, the difference shall be refunded to him or her pursuant to Chapter 5 (commencing with Section 5096) of Part 9 of this division, as an erroneously collected tax. If any taxes are paid under protest pursuant to this section, the taxing agency to which the taxes are paid may, in accordance with Section 26906.1 of the Government Code, impound those taxes until the final disposition of the claim or action respecting the protest. No impounding of taxes is required.

Cal. Revenue and Taxation Code - RTC § 621. Section 621.

In any county the assessor, with the approval of the board of supervisors, may give the information required by Section 619, and similar information with reference to personal property, as an alternative to giving the information by United States mail, by having published lists of assessments in newspapers, or by posting the information to the assessor’s Internet Web site, or any combination of the above. In counties of more than 4 million population and counties of more than 1 million population, as determined by the July 1, 1965, Department of Finance revised estimate, which are contiguous to a county with more than 4 million population, the assessor, with the approval of the board of supervisors, may divide the county into publication areas not to exceed five in number. Within such areas the assessment listing may be grouped by assessment map books, by post office zones or by such other arrangements as may be determined by the assessor as most likely to give notice to assessees and as practicable for publication in local newspapers. The complete assessment data of one such area may be printed in one year, and for other areas in successive years as directed by him or her until the full county is covered. Each year at least all changes of assessment listings for all the areas shall be printed, together with a notice that no changes were made with regard to properties not on the list of changes, so that all changes will be on a current basis for the entire county. Newspapers for the publications shall be selected as they are for publication of the delinquent tax lists and the rate paid for the advertising shall be the same. Neither the failure of the assessee to receive this information nor the failure of the assessor to so inform the assessee shall in any way affect the validity of any assessment or the validity of any taxes levied pursuant thereto.

Cal. Revenue and Taxation Code - RTC § 623. Section 623.

The assessor may place a single assessment on the roll for all leased personal property in the county that is assessed with respect to the same taxpayer. Any property assessed pursuant to this section shall, in the absence of evidence establishing otherwise, be deemed to be located at the taxpayer’s primary place of business within the county.
