Ohio Title Transfer for a Private Sale: Assignment, BMV 3770 and Tax

In an Ohio private-party car sale, the seller notarizes the assignment of ownership on the paper title (or completes form BMV 3770 if the title is electronic), the buyer takes that paperwork to a county Clerk of Courts title office within 30 days of the sale date, and the buyer pays Ohio sales and use tax on the purchase price plus title fees. The BMV does not print titles; clerks do. Miss the 30-day window and a late fee gets added on top of tax.

I read the Ohio BMV "How to Title" page in mid October 2026 and matched it against what county title offices actually ask for. Ohio's process looks simple until you hit an electronic title, a co-owner who is not present, an out-of-state title that needs a VIN inspection, or a salvage brand. Those are the deals that stall in the clerk's line on a Friday afternoon.

What the seller has to do

On a paper Ohio title, the Ohio BMV titles page says the seller completes the assignment of ownership section on the back and has their signature(s) notarized, then hands the title to the buyer. Photocopies are not accepted. If more than one owner is listed, dual ownership rules apply: both parties must be present at the title office unless a notarized power of attorney (form BMV 3771) is on hand. Social Security numbers for the parties are required.

If the title is electronic -- no paper sitting in a drawer -- casual sellers use form BMV 3770, Ownership Assignment and Title Application for Casual Sale. That form is not for dealerships or insurance companies. The seller fills page 1 and notarizes it; the buyer fills page 2 and notarizes it; then the buyer takes both pages to a clerk. Ohio Revised Code 4505.032 is the statute the BMV cites for that electronic assignment path. If the seller is a minor, form BMV 3751 (minor consent) is also required.

What the buyer brings, and the 30-day clock

The buyer shows up at a county Clerk of Courts title office with the assigned original title (or completed BMV 3770), acceptable ID, payment for title fees, and sales tax on the purchase price. The BMV is explicit that title transfers must happen within 30 days of the sale date or a late fee is assessed. The titles page does not publish the late-fee dollar amount, so ask the clerk when you book the visit rather than guessing from a forum post.

Sales and use tax is calculated on the purchase price, and rates vary by county. The BMV titles page points buyers to Ohio Department of Taxation materials for what counts in the taxable price and for county rate tables. That tax site blocked or 404'd our automated checks the night I wrote this, so treat the clerk's quote as the number that matters and bring a bill of sale that matches the price written on the assignment. Under-reporting the price is a bad idea; Ohio audits casual-sale figures.

Plates, temp tags, and out-of-state titles

If you want a 45-day temporary tag, the BMV says you must get it before you transfer the title into your name. Once an Ohio title exists, you can only buy permanent Ohio plates for that vehicle. Plan the order of operations: temp tag first if you need to drive home, then title, then registration at a deputy registrar.

Out-of-state titles need an Ohio VIN inspection before the clerk will convert them. Inspections are available at Ohio deputy registrar agencies, some Clerk of Courts title offices, and participating licensed Ohio dealers (fees vary; call ahead). Our VIN verification for title transfer post covers how to match the dash, door sticker, and title yourself first so you are not surprised at the inspection desk. Compare notes with how other states handle private sales in our Texas title transfer guide and Florida title transfer guide if you are moving a car across state lines.

Salvage, rebuilt, and flood brands

A salvage path is not a normal private-sale afternoon. To change an Ohio title to salvage, the owner marks Application Type -- Salvage on the back, notarizes it, and pays salvage title fees. A rebuilt or self-assembled vehicle needs an Ohio State Highway Patrol inspection before it can be titled again. If the car you are buying already carries a salvage or rebuilt brand, read our Ohio salvage and rebuilt title rules and Ohio salvage title buyer guide before you sign anything. Flood and rebuilt brands also show in federal data at NMVTIS.

History report before the notary appointment

Ohio's title assignment tells you who owned the car and whether a lien is noted. It does not narrate prior accidents, odometer rollbacks, or auction wholesale brands. Pull a fresh report yourself. We sell CARFAX and AutoCheck as a licensed reseller and are not affiliated with CARFAX, AutoCheck, or Experian; member pricing often lands near $4.50 for a CARFAX, guests closer to $5.50, and the AutoCheck bundle near $6.75, while buying direct is commonly $39.99 to $44.99 -- confirm at checkout. Background on private-party report use is in CARFAX for private-party sales, and CARFAX describes report contents here.
