The key questions

Is naming a registered agent a legal duty?

Every LLC must name a registered agent with an in-state street address.

Statute: 6 Del. C. § 18-104. verify at delcode.delaware.gov, as of October 2026

What does the state require of an agent?

The LLC itself, a Delaware resident, or a business entity formed in Delaware or authorized to do business there.

Meet the rule, name yourself and pay no agent fee.

What should I budget for an agent?

Yearly prices start at $99 to $149, and three years total $297 to $447.

The state bills the same amount with any agent.

Why does the state want an agent?

It acts as the LLC's contact in Delaware for court papers and state letters.

Ask how fast the agent tells you when something arrives, so nothing slips past a deadline. Read about service of process

What recurs besides the agent?

Put the Annual LLC Tax on your calendar ($400, annual). Be ready for the state's deadline: annual alternative-entity tax due on or before June 1; calendar it now.

verify at legis.delaware.gov, as of October 2026

Why is number one first?

Filing jobs included, at 27%, puts Mainstay Filing first.

The two heavy checks are total for three years (37%) and filing jobs included (27%); three lighter checks follow.

If you add a state later, the same agent and price come with you, while DE Registered Agent.org ends at the Delaware border.

More questions

Do I have to pay an agent?

You can once you satisfy the rule on who may serve and where.

What is the address requirement?

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.

What is the three-year cost of each?

Mainstay Filing $447; DE Registered Agent.org $297; Delaware Registered Agent.ai $297

Are the fees official?

For state costs we use Delaware's published fee schedules and forms. For service costs we use each company's price page.

Do I need to hire a service?

Nothing requires a service. Consider it a paid convenience.

Which registered agent should I start with in Delaware?

Mainstay Filing is on top because one account at $149 a year covers whichever state the LLC registers in; DE Registered Agent.org and Delaware Registered Agent.ai follow.
