Most states require you to title and register a newly purchased car within 10-30 days of the sale, using a bill of sale, the previous title (signed over), proof of insurance, and an odometer disclosure. Expect a title fee of roughly $15-$100+ plus a separate registration fee, and — separately — state sales or use tax, which varies enormously by state from 0% to over 8% of the purchase price.

Titling vs registering — different things
Titling establishes legal ownership of the vehicle in your name; registering is what allows you to legally operate it on public roads and typically renews annually or biennially. Both are usually handled at the same DMV visit or online transaction when you first acquire a car, but they serve different legal purposes.
Documents you'll need
- The previous owner's title, properly signed over to you (or a Manufacturer's Certificate of Origin for a new car from a dealer).
- A bill of sale showing the purchase price, used to calculate sales/use tax in most states.
- Proof of current auto insurance meeting your state's minimum requirements.
- A valid government-issued photo ID.
- An odometer disclosure statement, required by federal law for most vehicles under 20 years old.
Typical costs
Title fees are usually modest, often in the range of $15-$100 depending on the state. Registration fees vary far more, sometimes based on vehicle weight, age, or value. The biggest and most variable cost is sales or use tax on the purchase price itself — some states charge none, while others charge upward of 6-8%, and a few offer a trade-in tax credit that reduces the taxable amount.
Timelines and deadlines by state
Most states give buyers somewhere between 10 and 30 days from the purchase date to title and register a vehicle before late fees or penalties apply — check your specific state DMV's current deadline, since it varies and rules do change. Dealerships often handle the paperwork for you on a dealer purchase; private-party sales put the responsibility entirely on the buyer.
Buying out of state
If you buy a car in a different state than where you'll register it, you generally pay sales tax to your home state (not the seller's state) when you title and register it there, and you'll need to complete an out-of-state title transfer — plan for a possible temporary registration or transit permit to legally drive it home.
Common mistakes
- Missing the registration deadline and incurring late fees.
- Assuming a private seller's word on mileage instead of confirming the odometer disclosure matches the title.
- Not budgeting for sales tax separately from the purchase price when financing.
- Driving on an expired temporary tag without following up on permanent registration.
