Your New Hampshire car post-sale checklist

  1. 1

    Keep your signed New Hampshire bill of sale

    This is your proof that you sold the car on the sale date. If the buyer gets a ticket, is in an accident, or fails to transfer the title within 20 days from the sale date, the New Hampshire bill of sale shields you from liability. Keep both your copy and a scan for at least 5 years.

  2. 2

    File a release of liability with New Hampshire DMV

    Most New Hampshire sellers file this online through New Hampshire DMV within 5 days of the sale. Filing removes you from records as the registered owner so any post-sale tickets, tolls, or accidents become the buyer's responsibility, not yours. New Hampshire requires the buyer to title the car within 20 days — your release filing protects you if the buyer misses that deadline.

  3. 3

    Cancel or transfer your auto insurance

    Contact your insurer the same day you hand over the keys. New Hampshire does not require you to maintain insurance on a vehicle you no longer own, but you must not cancel before the sale is complete. If you are replacing the car with another, transfer the policy instead — many insurers offer a short grace period to bind coverage on the new vehicle.

  4. 4

    Remove your license plates

    In New Hampshire, plates go with the seller — not with the car. Remove the plate(s) before the buyer drives or rides away. You can return them to New Hampshire DMV or transfer them to your next vehicle.

  5. 5

    Verify the 20-day title transfer window

    New Hampshire requires the buyer to retitle the car at New Hampshire DMV within 20 days of the sale date. If you have not received confirmation that the title has been transferred by day 25, contact New Hampshire DMV with your bill of sale and release-of-liability filing number to confirm the change of ownership.

  6. 6

    Confirm your New Hampshire tax obligations (seller's side)

    New Hampshire does not impose state sales tax on private-party car sales (New Hampshire has no state sales tax; local permit fees vary). The buyer typically pays a flat title fee (~$25) at New Hampshire DMV. If you sold the car for more than your original purchase price, you may owe federal capital gains — most private car sales are at a loss and not taxable.

  7. 7

    Watch for liens or loan payoff confirmation

    If you had a loan on the car, confirm the lender received the buyer's payoff and has released the lien on the New Hampshire title before you deliver the title. New Hampshire uses TDMV 18A as the lien release form — your lender will file this with New Hampshire DMV to clear the title record.

New Hampshire lien release procedure

  1. Obtain Form TDMV 18A from the New Hampshire DMV or the lienholder.
  2. Lienholder completes and signs TDMV 18A releasing the lien.
  3. Submit TDMV 18A with the existing title and title application at a NH DMV office.
  4. Pay the title fee and receive a clean New Hampshire title.

Frequently Asked Questions — New Hampshire

How long do I have to file a release of liability in New Hampshire?

New Hampshire sellers should file a release of liability with New Hampshire DMV within 5 days of the sale. Most New Hampshire sellers can file this online directly through New Hampshire DMV. Filing removes you from records as the registered owner so any post-sale tickets, tolls, or accidents fall on the buyer.

What is the New Hampshire title transfer deadline for a car?

New Hampshire requires the buyer to title the car within 20 days of the sale date. Missing the deadline can trigger late fees and back-dated registration penalties.

Do I owe New Hampshire sales tax on the car I just sold?

New Hampshire does not impose state sales tax on private-party car sales. New Hampshire has no state sales tax; local permit fees vary. Sellers generally owe no New Hampshire sales tax. You may owe federal capital gains tax if the car sold for more than your original purchase price — most private sales are at a loss and not taxable.

Does New Hampshire require a notary on the car bill of sale?

No. New Hampshire does not require notarization for a private car bill of sale. A signed bill of sale with both parties' full names, addresses, signatures, and the date is sufficient for New Hampshire DMV.

How does the buyer register the car in New Hampshire?

The buyer brings the signed bill of sale and endorsed title to New Hampshire DMV, pays the title fee (~$25) plus any applicable use tax, and receives a new New Hampshire title in their name. Transfer must be completed within 20 days of the sale date.

What if the buyer hasn't transferred the title yet?

In most states this is the buyer's responsibility, not yours. Filing a release of liability with your state DMV is the seller-side protection — it removes you from records as the registered owner so any post-sale tickets, accidents, or tolls fall on the buyer regardless of when the title is actually transferred.

Do I need to keep the bill of sale after the sale is complete?

Yes — keep your signed bill of sale for at least 5 years. If a parking ticket, toll, or accident occurs after the sale but before the buyer transfers the title, the bill of sale is your proof that the car was sold on the sale date. Store a scan and the original.
