Each person owning taxable personal property, other than a manufactured home subject to Part 13 (commencing with Section 5800), having an aggregate cost of one hundred thousand dollars ($100,000) or more for any assessment year shall file a signed property statement with the assessor. Every person owning personal property that does not require the filing of a property statement or real property shall, upon request of the assessor, file a signed property statement. Failure of the assessor to request or secure the property statement does not render any assessment invalid.

assessor between the lien date and 5 p.m. on April 1. The penalty provided by Section 463 applies for property statements not filed by May 7. If May 7 falls on a Saturday, Sunday, or legal holiday, a property statement that is mailed and postmarked on the next business day shall be deemed to have been filed between the lien date and 5 p.m. on May 7. If, on the dates specified in this subdivision, the county’s offices are closed for the entire day, that day is considered a legal holiday for purposes of this section.

The property statement may be filed with the assessor through the United States mail, provided that it is mailed in a manner that includes a postmark and is properly addressed with postage prepaid.

The continuance shall extend the two-year period specified in subdivision

(i)
Notwithstanding any other provision of law, every person required to file a property statement pursuant to this section shall be permitted to amend that property statement until May 31 of the year in which the property statement is due, for errors and omissions not the result of willful intent to erroneously report. The penalty authorized by Section 463 does not apply to an amended statement received prior to May 31, provided the original statement is not subject to penalty pursuant to subdivision (b).
