UNPAID PROPERTY TAXES

Tim LeFever and Ken Mattson had purchased over 120 properties (still own over 60 as of May 3, 2026) in Sonoma Valley using multiple LLCs and Limited Partnerships. According to Sonoma County’s web site for property tax information, all but 1 of the properties had delinquent and/or defaulted property taxes (taxes that were not paid by their due date). Property taxes owed are for payments that were due in December 2023, April 2024, December 2024, and April 2025. In April 2025, the total Sonoma County property tax owed total more than $4.1 million.

The property owned is split between the properties owned by KS Mattson Partners, LLC and LeFever Mattson company, including associated corporations. LeFever Mattson and the associated corporations are in chapter 11 bankruptcy. While in bankruptcy, LeFever Mattson and KS Mattson Partners are prohibited from paying these property taxes, without the approval of the bankruptcy court. Even so, nearly half a million dollars of the late property taxes owed by LeFever Mattson were late prior to filing bankruptcy. As the properties sell, the property tax is finally getting paid, so the county is now getting the money owed to it.

As of April 28th, 2025, amount of late property taxes:

$1,199,819.45 KS Mattson Partners

$2,936,297.10 LeFever Mattson

$4,136,116.55 TOTAL

$449,981.93 LeFever Mattson property taxes late prior to bankruptcy filing
