County Assessor and Tax Collector warn of false ‘1098-SR’ property tax claims targeting seniors
Deva Marie Proto, Sonoma County Clerk-Recorder-Assessor, and Erick Roeser, Sonoma County Auditor-Controller-Treasurer-Tax Collector, are warning seniors and other property owners about false online claims and scam calls urging them to file a so-called ‘Form 1098-SR’ to reduce or freeze property taxes or avoid school bonds. No such IRS form exists, and these messages are not legitimate.
