  • 2020 due date is July 31st 
  • There is approximately 5,600 Mobile Home tax bills sent out in Lake County.
  • Owners of the Mobile Home on January 1 of each year are responsible for the tax.

There is a $5.00 fee to obtain a Tax Certification through the Treasurer's office.  We accept certified funds only.  Please bring the original title to obtain a certification.
  • Senior citizens and disabled persons should contact the Lake County Treasurer’s Office for possible exemptions.
IMPORTANT CHANGE TO MOBILE HOME PROPERTY TAX LATE PENALTIES
Last year, Treasurer Holly Kim worked hard with Lake County state representatives to pass HB 925.  Under the new law, the penalties for late payment of mobile homes taxes in Lake County are capped at $100 or 50% of the original tax bill - whichever is lower.  This assures that going forward, your late penalties will never be higher than your tax bill.  It's one way we can care for our mobile homeowners and provide relief in this difficult time.
