Franklin County Auditor Forms

Franklin County Auditor forms homeowners use most

All of these are in the Franklin County Auditor Form Center. State-numbered forms such as the DTE 105A form (Homestead) and the DTE 105C form (owner occupancy) are also published by the Ohio Department of Taxation; for Franklin County filings, use the Auditor’s versions.

Tax reduction and exemption forms

Value and assessment complaint forms

Filing methods, evidence and deadlines are covered in the Board of Revision.

Transfer, conveyance and records forms

Moving property into an LLC also needs an affidavit of facts supporting the exempt status. See the transfers.

Farmland forms

Manufactured and mobile home forms

Homestead applications for manufactured and mobile homes are due December 31 of the prior year, earlier than for real property.

Rental registration forms

Franklin County requires owners of residential rental property to register it with the Auditor. The Form Center includes the Rental Registration Form, a Rental Registration Exception form, and a form to Request Owner Occupied Credit Removal or report rental registration non-compliance. Registration is due within 60 days after notification following a transfer, after receiving the tax bill, or after any change in the information; non-compliance carries a $150 fine per property per tax year. The Auditor also offers online registration.

Licensing and consumer forms

Public records, unclaimed funds and translated forms

• Public Records Policy and Records Request Form for requesting Auditor records.
• Unclaimed Funds Claim Form, one per unclaimed entry. See the unclaimed funds.
• Peace Officer Affidavits (current and former) related to shielding officers’ information on the Auditor’s website.
• Translated forms: the Form Center offers brochures and claim forms in Chinese, Nepali, Somali and Spanish.

Franklin County Auditor forms by life event

Most people don’t go looking for a form number; they go looking for help with something that just happened. Here’s which forms usually go with which event.

How to submit Auditor forms

Submission methods vary by form. The general options:

Making sense of form numbers

• DTE 1 and DTE 2 are Board of Revision complaints; an “M” suffix (DTE 1M) marks the manufactured home version.
• DTE 23 family forms deal with exemptions and penalty remission.
• DTE 100 family forms deal with conveyances; “EX” means exemption.
• DTE 105 family forms are the Homestead and owner occupancy applications, with letters for each type (A, C, E, G, H, I, J, K).
• DTE 106B is the complaint about a Homestead or owner occupancy denial.
• DTE 109 and 115 relate to CAUV.

Track what you file

Keep a copy of every form, note the date and method you used, and save any confirmation email or receipt. For Board of Revision complaints, the BOR Status tab on your parcel in the property search shows whether a complaint is on file. For Homestead, you’ll receive a certificate within 30 days after the application is processed.

Tips for completing a Homestead application (DTE 105A)

• Confirm you owned and lived in the home on January 1 of the tax year you’re applying for.
• Use the right income year: 2026 applications use 2025 income. For 2025 Ohio returns, the Department of Taxation says MAGI is Line 3 of the Ohio return plus Line 13 of the Schedule of Adjustments.
• Attach DTE 105E if you’re applying through disability, DTE 105H if you didn’t file returns, and DTE 105G if you’re grandfathered.
• Apply by December 31. See the Homestead.

Tips for completing a Board of Revision complaint (DTE 1)

• Use your exact parcel number and owner name from the Auditor’s record.
• On Line 9, enter your opinion of full market value, the current value and the change you seek.
• Attach full signed sale documents or a full appraisal report if you rely on them.
• If the owner is a company or trust, an attorney is strongly recommended.
• File by March 31, and earlier if you can.

Tips for conveyance forms (DTE 100 and DTE 100EX)

• Report the full consideration (sale price) on DTE 100; the fee is figured on the price rounded up to the nearest $100.
• Claim an exemption only if the transfer fits a category listed on DTE 100EX; money changing hands generally makes a transfer taxable.
• For transfers into an LLC, add the affidavit of facts the Auditor requires.
• Check the Auditor’s Conveyance Standards for document requirements. See the transfers.

State versions of DTE forms

DTE forms are statewide, and the Ohio Department of Taxation publishes real property tax information and forms on its real property pages. For Franklin County filings, use the versions in the Auditor’s Form Center, which include any county-specific instructions, addresses and online options.

Forms for landlords

• Rental Registration Form (or register online): required for residential rentals, within 60 days after notification following a transfer, receipt of the tax bill, or a change in information.
• Rental Registration Exception: for properties that qualify for an exception.
• DTE 2: to dispute the $150 rental registration fee at the Board of Revision.
• Request Owner Occupied Credit Removal: to remove the owner occupancy credit when a home becomes a rental.
• DTE 1: to challenge a rental property’s value.

Where to get help filling out forms

• Homestead: the Homestead office at 614-525-3240, and application clinics on the Auditor’s events calendar.
• Transfers and name changes: Transfer & Conveyance at 614-525-3253; the Franklin County Law Library offers free document templates, though the Auditor can’t prepare documents.
• Board of Revision: 614-525-3913 or BOR@franklincountyohio.gov.
• CAUV: 614-525-6254 or CAUV@franklincountyohio.gov.

Forms for farmers and rural owners

• DTE 109 for CAUV entry and the annual renewal; see the CAUV.
• DTE 102 when selling CAUV land.
• DTE 115 to ask about deferring recoupment in certain conversions.
• ODA 11 for placing farmland in an agricultural district.
• DTE 26 after storm or fire damage to farm buildings.

Forms for value questions

If your question is about your property’s value, the path depends on the problem: factual errors go to the appraisal staff without a form, while disagreements over market value use DTE 1 at the Board of Revision. The property values explains the difference.

Form deadlines in date order

Tips to avoid a rejected form

1. Use the current version from the official Form Center, not an old copy.
2. Include the parcel number on every property form. Our parcel lookup shows where to find it.
3. Sign and date where required; unsigned forms are a common reason for delays.
4. Attach the addenda that apply (for example DTE 105E or 105H with a Homestead application).
5. Keep a copy and note when and how you submitted it.
6. Ask before the deadline. The Auditor’s main line is 614-525-4663; Homestead is 614-525-3240.

Which office each form goes to

Documents you won’t find in the Auditor’s Form Center

• Deeds are prepared by a title company, attorney or the parties; the Franklin County Law Library offers free templates.
• Recording happens at the Recorder’s Office.
• Tax payments go to the Treasurer, not with an Auditor form.
• Board of Tax Appeals filings are made with the BTA (DTE 4 is listed for convenience).
• Zoning and building permits come from your city, village or township.

Your parcel number on forms

Nearly every Auditor form asks for the parcel number, and it’s the detail most likely to be mistyped. Copy it from your tax bill or your record in the property search, in the 000-000000-00 format, and check it against the property address before you sign. If your home sits on more than one parcel, check the form’s instructions on whether to list each one or file separately. Our parcel number explains how to find the number and what each part means.
