How Lake County Assesses Property
Assessed by: Lake County Auditor's Office
Assessment cycle: Sexennial reappraisal with triennial updates
Notices typically mailed: Spring (typically by mid-April)
In Lake County, property taxes are based on assessed value, which is 35% of your home's market value as determined by the County Auditor. For example, if your home's market value is $154,000, your assessed value would be $53,900 (35% of $154,000). At Lake County's effective tax rate of 1.54%, this would result in approximately $830 in annual property taxes. The county conducts a full sexennial reappraisal every six years and a triennial update in the middle of each cycle, with the last reappraisal in 2021 and a triennial update completed for tax year 2024.
The Appeal Process
Appeals are heard by the Board of Revision. The Board of Revision is a three-member panel consisting of the County Auditor, County Treasurer, and President of the County Commissioners. This is a legal proceeding where the Board determines the fair market value of your property as of the January 1 lien date. You may represent yourself or hire legal counsel, and you can attend in person or submit your case based on written evidence.
Obtain your property's current assessed value from the Lake County Auditor's website at auditor.lakecountyohio.gov or from your assessment notice (typically mailed in spring by mid-April)
Gather evidence to support your appeal, including: recent appraisals (as of January 1), comparable sales data, photos of property damage, construction costs for newer homes, mortgage appraisals, or market analysis from a real estate professional. Submit evidence with your DTE1 form or at least 5 days before your hearing.
File your appeal using the Complaint Against Valuation of Real Property (DTE1) form between January 1 and March 31. File online via SmartFile system (preferred), by mail with notary seal, in person at the Auditor's office, or via email. The filing deadline is March 31 at 4:30 PM EST.
After filing, your appeal and evidence will be reviewed by a staff appraiser who makes recommendations to the Board of Revision. You may be scheduled for an informal hearing where you can present your case and evidence to support your requested value.
The three-member Board of Revision (consisting of the County Auditor, Treasurer, and County Commissioner President) will conduct a hearing to determine the fair market value of your property. You may attend in person, have legal representation, or submit your case based on written evidence.
If you disagree with the Board of Revision's decision, you may file an appeal with the Ohio Board of Tax Appeals using Form DTE 4 within 30 days after the Board's decision notice is mailed.
As a final option, you may also appeal the Board of Revision's decision to the Lake County Court of Common Pleas within the statutory time period.
