Our top pick

1. DE Registered Agent.org: best for a Delaware LLC that expects to stay at home

$199 to form, then $99 a year for the agent, and the state fee on top

Editor score9.6out of 10

DE Registered Agent.org takes the top spot because the Delaware formation runs $199 above the state's fee, with the registered agent free for a year and $99 yearly to keep the agent.

The registered office is an in-state street address supplied by the plan, and any papers served on the company show up as scans in your online account.

Its published prices leave out the Annual LLC Tax, so the owner files it with Delaware every year.

It costs less than Mainstay Filing over three years, and cost is one of our two heaviest criteria.

In the price

  • Year one as your registered agent

Good

  • Covers your first year of registered agent service
  • Files the LLC for $199 and the state fee

2. Mainstay Filing: best for formation, agent and annual tax at one price

$199 a year, with the state fee added ($309 due at checkout)

Editor score9.1out of 10

Mainstay Filing makes the list at number two because $199 a year pays for the Delaware filing, a year as your registered agent and the annual tax, and the renewal is $199.

Renewal includes Mainstay filing the Annual LLC Tax on your behalf. The state fee in Delaware is $400 every year, due annual alternative-entity tax due on or before June 1, with $200 added if it is late, and Mainstay passes that fee through at cost.

DE Registered Agent.org undercuts it by $200 across three years, which leaves Mainstay Filing second on cost.

In the price

  • The formation filing, submitted on your behalf
  • Your registered agent for the full year
  • Your annual tax, prepared and filed for you
  • EIN application handled

Good

  • A single $199 yearly price that covers the annual tax
  • Renews at $199 with no add-ons
  • Delaware's fee is added at cost
  • EIN application is part of the package

Watch for

  • The agent part costs $100 a year more than DE Registered Agent.org's after year one

Why these made the shortlist

Two criteria count most here, three-year price and what the price covers, at 28% each, while renewal terms, fit for the state and price clarity divide 44%. What tipped Delaware was three-year price.

DE Registered Agent.org adds up to $397 over three years, which is $200 below Mainstay Filing. Mainstay would file the Annual LLC Tax too, but an owner can do that alone for the state fee, so the smaller price won this page.

Every criterion and weight is set out on How we rank.
