  1. You changed the value of my property – why?

    Under Ohio Revised Code, the County Auditor is required to determine the taxable value of real property. As part of this duty, you will see regular changes to your property value. There are several reasons why our office might have updated your property value. This includes:
    • Scheduled Revaluation – this is also called the sexennial value review and occurs every 6 years
    • Update Schedule – this is also called the triennial value review and is performed once half-way through the revaluation schedule
    • Construction -You have started or completed construction on your property as determined by permits you have been issued
    • Incorrect data affecting value - in the course of business we discover incorrect data, or the owner or a realtor brings incorrect data to our attention. Examples of this may include incorrect square footage or number of bathrooms
    • Board of Revision decision
    • Special Requests:  Special requests by owner or BOR to verify data or check for condition, etc.
    • Damaged/Destroyed Property:  A damaged/destroyed property form prompts our office to visit the property to assess condition issues generally due to inclement weather damage or fire, etc.
    • Internal Consistency Review:  The office may note inconsistencies of value within a specific area during the normal course of business which will prompt a value review of all properties in that area


  2. I think your valuation of my property is incorrect. What can I do?

    The appraised value set by the Auditor's Office is an important part of the property tax calculation. If you feel the appraised value is too high, you may file a complaint with the Franklin County Board of Revision. Filing a BOR complaint entitles you to a hearing before the three-member Board of Revision. At the hearing, you may present information such as recent appraisals or current sales data for similar properties in your neighborhood to support your complaint. There are several ways to file a complaint: you can file your complaint by U.S. Mail or in person at: 373 S. High St., 20th Floor, Columbus, OH 43215; you can scan your signed and notarized complaint and email it to:; or fax it to: 614-525-6252. You can obtain blank complaint forms (form DTE 1) through our Form Center.
    Complaints can be filed between November 30 and March 31. Complaints must be received by our office on or before March 31. If a complaint is filed by mail or certified mail, and has a United States postmark (on the envelope or sender's receipt) of March 31, it will be considered filed on March 31.

  3. What is mediation?

    Mediation is a method by which tax payers can settle Board of Revision cases without a full hearing. This process involves the tax payer, an independent mediator and a representative from FCAO.  During the process, the mediator assists with communication and negotiation between the tax payer and the representative to help them in reaching a voluntary agreement regarding their dispute. The Board of Revision must approve any agreement which is reached in mediation. For additional information on the mediation process, including whether you can qualify, please visit here.


  4. How do I get a dog license?

    There are several ways to obtain a dog license. First, you may call the Franklin County Auditor's Consumer Services Division directly at 614-525-3260 and an application will be mailed to you. Dog licenses can also be obtained at Franklin County Animal Control, the Capital Area Humane Society and other satellite locations throughout the county, or can be accessed online. Calling can help eliminate confusion about different costs in licensing for animals that have been spayed or neutered and those that have not. Licensing fees may be prorated if they are issued after July 1 for their given year. For more information on dog licensing FAQs, please click here.


  5. When is a vendor's license required and how do I get one?

    A vendor's license is required by state law whenever a business makes retail sales. Having a vendor's license enables the business owner to collect sales tax for the State of Ohio. The initial license is issued by the county auditor's office in the county in which the business is located. Because there are a number of different vendor's licenses, it is best to contact the Franklin County Auditor's Office Consumer Services Division directly at 614-525-3260 to determine which type of license you will need. You may also visit the State of Ohio Department of Taxation website.
