The lesson, step by step

  1. Step
    1

    Decide whether Delaware registration is required

    A foreign LLC is simply one formed in another state, and it registers before doing business in Delaware. Operating unregistered means: A suit started by an unregistered LLC will not be heard there (6 Del. C. 18-907(a)). Signed contracts keep their force (6 Del. C. 18-907(b)).

    Where this comes from: Class notes: corp.delaware.gov (October 2026)

  2. Step
    2

    Obtain your home state's certificate

    Order certificate of existence from the jurisdiction of formation, dated within 180 days.

    Time the order so the certificate is recent at filing.

  3. Step
    3

    Line up a Delaware registered agent

    Every LLC must name a registered agent with an in-state street address. The address has to be a registered office in Delaware. An entity agent keeps a business office there that is generally open; an individual agent has to be generally present there. A virtual office or mail-forwarding service alone does not qualify.

    Each of our picks includes the registered agent.

    Where this comes from: Class notes: delcode.delaware.gov (October 2026)

  4. Step
    4

    Fill out and file the Certificate of Registration of a Foreign Limited Liability Company

    That filing is the registration, and the state charges $200 for it.

    Plan for the recurring filing

    What recurs is the Annual LLC tax, $400, June 1.

Filing to registerState office$200

Optional serviceYour service$199 in the first year
Three years of state feesState office$1,000
State amounts come from Delaware's official schedules (see the references); service prices come from each company's site. The three-year state total adds the filing, the reports from year two and any yearly minimum tax.

Why Mainstay Filing comes first

edged ahead of on homework the price handles, which counts for 33%.

DE Registered Agent.org has the lower renewal, yet covering several states counted for more.
