The 5 steps to file a DBA in New Hampshire

Search before you file; a DBA does not stop someone else using a similar name.

  1. 1

    Decide whether you need one

    Before you file

    You need a DBA when the LLC uses a name on signs, invoices or a website that is not its exact legal name. If the old name should disappear entirely, change the legal name instead.

  2. 2

    Search the name

    Free to search

    Check the New Hampshire business register and a trademark search before you print anything. New Hampshire name search.

  3. 3

    File the DBA with the state

    We file this one

    You file it with New Hampshire's business filing office; New Hampshire's fee is $50 (New Hampshire fee schedule). The current form is on New Hampshire's official site. We file it for $200 plus the state fee.

  4. 4

    Check for city or county filings

    Where people get stuck

    Some states also have counties or cities register trade names, and some require publishing a notice. The state filing office can tell you what applies where you operate.

  5. 5

    Open the bank account in the DBA

    After it is filed

    Banks usually ask for the filed DBA before they let the LLC take payments in that name.
