1Our first answer
1. Delaware Registered Agent.ai: best for registering in one place
Service $199 plus $200 to the state; agent renewal $99
Delaware Registered Agent.ai comes first: it charges $199 with the first year of agent service included, then $99 annually.
For a company that stays put, the lower three-year price than Mainstay Filing earns it the top spot.
By year three the state will have collected $1,000. looked up at delcode.delaware.gov in October 2026 to confirm
What registers the LLC?
The Delaware Department of State, Division of Corporations handles it: submit the Certificate of Registration of a Foreign Limited Liability Company there and the LLC is registered once accepted.
Enclose certificate of existence from the jurisdiction of formation dated no earlier than 180 days.
What do I owe once the LLC is registered?
Afterward comes a Annual LLC tax at $400.
Timing, in the state's words: June 1.
Why is the list in this order?
On what you pay over three years, worth 33%, Delaware Registered Agent.ai comes out ahead.
We weigh five questions: what you pay over three years (33%), chores the price takes care of (29%), answers on the price page (14%), what happens at renewal (13%) and room to add states (11%).
Delaware Registered Agent.ai totals $397 across three years, which is $100 under Mainstay Filing.
How was the bottom line figured? Add the filing fee, the next two reports and the minimum tax if the state has one. Anything with no fixed price, a newspaper notice for instance, is described above and kept out of the sum.
Questions people also ask
Do I still need an agent in my home state?
Probably. Your home state still wants an agent of its own. A company that operates in every state, Mainstay Filing for example, can hold both roles, whereas a local firm covers a single state.
What do the picks cost over three years?
Three-year totals: Delaware Registered Agent.ai $397, Mainstay Filing $497, DE Registered Agent.org $397, before state fees.
Where do these numbers come from?
State fees come from Delaware's official documents, and service fees come from each company's own pricing page. Both carry dates on this page.
Do I have to use a service?
No. What the law asks for is a filing, and it does not say who has to send it.
Will a service file the registration for me?
Each of them submits it for you, and the state fee is not affected by that choice.
Who should I ask first about a foreign registration service in Delaware?
Ask Delaware Registered Agent.ai first, then compare Mainstay Filing and DE Registered Agent.org.
