Los Alamos Assessor Reminds Businesses to File Personal Property Declarations

Los Alamos County Assessor George Chandler mailed annual Business Personal Property Declaration forms to local businesses, and the public notice associated with that mailing lists Feb. 28 as the due date in its headline. The body of the county notice available to this reporter did not include a filing deadline or instructions for submissions, so Los Alamos businesses should confirm the final date and filing methods with the Assessor’s Office.

Nearby Bernalillo County has issued a detailed timeline that illustrates how deadlines can vary by jurisdiction. The Bernalillo County Office of the Assessor, in a Feb. 25, 2026 release, noted that "Business Personal Property (BPP) renditions are traditionally due in the Office of the Assessor by the final day of February." For 2026 the office extended the deadline to Monday, March 2 because Feb. 28 falls on a non-business day, and the release states plainly that "Renditions must be postmarked no later than March 2."

Bernalillo’s release lays out submission channels and penalties. Business owners may submit renditions by email to BPP@bernco.gov, by fax to 505.222.3771, in person at 415 Silver Ave., SW, Albuquerque, NM 87102, or by mail to PO Box 27108, Albuquerque, NM 87125. The Assessor’s Office can be reached at 505-222-3750 and the release directs readers to bernco.gov/assessor, noting that forms are available in English and Spanish. The release warns that "Business owners who fail to file a BPP rendition are subject to a 5% penalty which is added to the 2026 Notice of Value and subsequent tax statement." The office adds an exhortation: "Don’t delay, file your BPP renditions TODAY," and states "Assessor’s staff are standing by to help! Call the Office of the Assessor at 505-222-3750 or visit bernco.gov/assessor and find forms in both English and Spanish." Press inquiries may be directed to Tom Thorpe, communications specialist, at 505-270-8952 or tthorpe@bernco.gov.

Los Alamos businesses lack comparable public filing details in the notice provided here. The county fragment names County Assessor George Chandler and confirms the mailing of the BPP Declaration forms, but does not list submission methods, postmark rules, or penalties. Reporters and taxpayers should contact Los Alamos County Assessor George Chandler to confirm whether the Feb. 28 date in the headline is the official deadline or whether an extension applies for 2026.

For businesses that operate across state lines, Kansas forms follow different rules: PV-PP-1A (Rev 11/24) instructs that new property or changes must be filed with the county appraiser by March 15, and lists assessment percentages such as "2.1 RESIDENTIAL MOBILE HOMES 11.5%" and "2.3 PUBLIC UTILITIES (Locally Assessed) 33%" and a separate "WATERCRAFT (separate Const. category) 5%." Schedule 6 items such as ATVs, off-road motorcycles and non-commercial trailers must be reported to the county appraiser on or before December 20 to allow prorated values.

With Feb. 28 and Bernalillo’s March 2 postmark deadline imminent, local businesses that received Los Alamos forms should verify the precise deadline, submission methods and penalty rules with the Los Alamos County Assessor’s Office; businesses operating in Bernalillo County should use the contacts and submission channels listed above to avoid the 5% penalty on the 2026 Notice of Value and subsequent tax statement.
