Frequently asked questions
Common questions about Franklin County, Ohio valuation complaints — deadlines, how filing works, and how NeighborComp Ohio fits in.
Free guides & getting started
Is there a free guide before I buy anything?
Yes. Our free complaint guide explains how Franklin County values homes, what the Board of Revision considers, what evidence helps, and the basic filing steps.
Can I get a simple filing checklist?
Yes. The free checklist helps you gather your parcel number, property details, comparable-sales evidence, deadline, official filing link, and confirmation details before you begin.
About NeighborComp Ohio
Is NeighborComp Ohio a government office?
No. NeighborComp Ohio is a private company and is not affiliated with the Franklin County Auditor, the Board of Revision, or any government office. We provide information and a do-it-yourself packet — we do not file complaints for you and we do not give legal advice.
Do I need a lawyer to file a valuation complaint?
Usually not. Individual homeowners can file their own Board of Revision complaints. Properties owned by business entities or trusts, unusual properties, or parcels with prior complaints can require additional review — our packet is built for individually owned residential homes.
How do you decide if my home is worth reviewing?
We compare the county's appraised (full market) value of your home with recent arm's-length sales of similar homes nearby, using Franklin County public records. If the county's value is meaningfully higher than what similar sales support, a complaint is worth a closer look.
Is the check really free?
Yes. Enter your address or parcel number and see your result in seconds — no account or email needed. If the county's value looks reasonably supported, we'll tell you that too — no packet needed.
Deadlines
When can I file a complaint?
The Franklin County Board of Revision filing season is expected to reopen in November 2026. The county lists March 31, 2027 as the complaint deadline for tax year 2026. Check our filing dates page — we recheck the county's official pages before publishing changes.
What is the difference between the tax year and the filing year?
Ohio complaints are filed for a tax year — the year the value was set — but you file during the following filing season. For tax year 2026, the complaint deadline is March 31, 2027.
What happens if I miss the deadline?
The March 31 deadline is set by Ohio law and missed deadlines generally can't be reopened. You would wait for the next tax year's filing season.
Where do I confirm the exact dates?
Our filing dates page lists each date with its status and a link to the official county source. Always confirm on the county's site before filing.
The filing process
How do I actually file a complaint?
You file a Complaint Against the Valuation of Real Property (Form DTE 1) with the Franklin County Board of Revision. You fill in your parcel number, owner information, and the value you believe is correct, and attach your evidence. Our guide walks through each step.
What evidence makes a strong complaint?
Recent arm's-length sales of similar homes near yours, corrections to errors in the county's record of your property, and photos or estimates for condition issues. That's exactly what our free check and the packet organize for you.
What is the 35% assessed value?
Ohio taxes 35% of the county's appraised (market) value. The Board of Revision decides the full market value — never compare your taxable assessed value directly with a home's sale price.
How long does a decision take?
It varies. The Board reviews complaints, may hold a hearing, and issues a written decision. The school district can also file a counter-complaint, which you can respond to.
Does filing a complaint raise my taxes?
A complaint asks the Board to lower the value to match the evidence. You present your own case; the Board decides.
The packet, refunds & your order
What's in the $79 packet?
A PDF with your property and county-value summary, a comparable-sales table with sources, the differences explained, a record-error checklist, an evidence list, current complaint-form guidance, official filing links, and submission plus hearing-prep checklists.
What if my complaint doesn't lower the county's value?
Request a refund within 12 months of purchase with your order number, checkout email, and the Board of Revision decision. We review each request manually and refund approved requests to your original payment method — see the refund page.
How do I get my packet again or check my refund?
Use the order lookup page with your order number and checkout email. No account needed.
Are savings guaranteed?
No. We never guarantee tax savings or county approval. The Board of Revision decides every complaint.
Is the packet a certified appraisal?
No. The packet is an educational, do-it-yourself document built from public records. It is not a certified appraisal and not county-approved evidence.
