Mobile Home Tax Bills - Treasurer's Office

Mobile Home assessments are determined for tax purposes in January of each year. The owner of record as of January 1st, is responsible for that year's Mobile Home taxes. Although the County Clerk computes the Mobile Home Tax Bill, it is the Treasurer's Office that has the function of mailing them out and collecting the current tax year payments.

Mobile Home Taxes are due on Friday, July 7, 2023.

Taxes not paid by July 7, 2023, will be charged $25 per month in interest, up to $100.

Any mobile home that has outstanding taxes owed as of December 4, 2023, will be sent a certified notice, published in the local newspapers, and charged an additional $10 fee.

The last day that mobile home taxes can be paid in the Treasurer’s Office is December 27, 2023. Mobile Home Taxes billed in 2023 that are not paid by December 27, 2023, will be sold at the annual Tax Sale. The annual Tax Sale will take place on December 28, 2023.

Note: If you determine an error with your Mobile Home Tax Bill, the owner of the mobile home may complete a Mobile Home Registration Change Form to contest the bill within six months from when it is mailed. Once completed, the Mobile Home Registration Change Form should be returned to the Rock Island County Clerk's Office.

When purchasing a new or used Mobile Home, the owner of each inhabited mobile home located in the State of Illinois must file a mobile home registration form within thirty (30) days with the County Clerk's Office.

Mobile home park operators shall forward a copy of the mobile home registration form to the County Clerk's Office within five days of the entry of a mobile home into such park.

The owner of a mobile home not located in a mobile home park shall, within 30 days after initial placement of such mobile home in any county and within 30 days after movement of such mobile home to a new location, file with the County Clerk's Office, a mobile home registration.

Note: Locating a mobile home outside of a mobile home park typically requires a "Special Use" permit. Check with the Zoning Office in that jurisdiction.

Failure to register does not relieve tax liability.

The mobile home registration form must show the following:

  • The name, address of the owner
  • The location, the year of manufacturer, and the total square feet of the mobile home
  • The date that the mobile home became inhabited
  • The date the mobile home was initially placed in the County, or was moved to a new location

You may either download the Mobile Home Registration form (PDF) or you may obtain one directly from the Rock Island County Clerk's Office.

It shall be a Class B misdemeanor to fail to submit information required. Any person furnishing misinformation for purposes of registration or failing to file a required registration is guilty of a Class A misdemeanor.

Delinquent Tax Payments - County Clerk's Office

Mobile Home Taxes not paid by the day before the annual tax sale in December, will be sold at the annual tax sale. The annual tax sale will take place in December. Once the tax sale is complete, the County Clerk is responsible for receiving payments for delinquent taxes. All payments made on delinquent taxes for a parcel, must be paid in full at one time. No partial payments are accepted. Payments should be made payable to the Rock Island County Clerk by one of the following methods:

  • Cash
  • Cashier's Check
  • Certified Check
  • Money Order

Delinquent taxes that have been sold at a tax sale give tax buyers the opportunity to gain title to the mobile home if the taxes are not redeemed within two years to six months.

Moving Certificates - Treasurer's Office

Before moving a Mobile Home, you must obtain a "moving certificate" from the Rock Island County Treasurer's Office. Note that the State of Illinois requires that all taxes are to be paid before a Mobile Home can be moved. There is no charge for the moving certificate, but if you move a Mobile Home without a "moving certificate", you are guilty of a Class B misdemeanor.

When moving a Mobile Home, any land owner on which an inhabited mobile home is located is required to complete and file the Mobile Home Registration Form with the Rock Island County Clerk's Office. This must be completed within thirty days.

Tax Clearance Certification - Treasurer's Office

Fee of $5 will be charged.

Before buying a Mobile Home, please contact the Rock Island County Treasurer's Office to ensure there are no outstanding tax bills or liens against it. If you purchase a Mobile Home with a lien, you will not get a clear title to your mobile home.

The State of Illinois requires all taxes paid before any changes can be made on a mobile home title. The Tax Clearance Certification Form is completed by the Treasurer's Office for a $5 fee. The Treasurer's Office will need the mobile home title to complete the Tax Clearance Certification Form. You will then need to take the mobile home title and completed Tax Clearance Certificate to an Illinois Secretary of State Office in order to process any necessary changes to that title.
