What you probably want to know

Is a registered agent a legal requirement?

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

The law behind it: 6 Del. C. § 18-104. check it at delcode.delaware.gov, October 2026

Can anyone do it?

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

You can skip the fee entirely if you meet the rule.

How much per year for an agent?

Prices start at $99 to $149 a year, and three years total $297 to $447.

No state fee depends on which agent you pick.

What does the agent handle?

It accepts legal papers and state notices for your company, using an address in Delaware.

Service is only as good as the forwarding, so ask how documents reach you. What being served means

Are there yearly charges besides the agent?

One thing keeps recurring, the Annual LLC Tax, each year, costing $400 a time. As the state words it, it's due annual alternative-entity tax due on or before June 1, and that's easy to forget.

check it at legis.delaware.gov, October 2026

What put number one on top?

Work taken off your hands, worth 31%, put Mainstay Filing first.

Five checks set the order: cost across three years (33%), work taken off your hands (31%), prices stated clearly (14%), renewal price (12%) and where it works (10%).

It's the only pick that works in all fifty states, which pays off the day your LLC registers elsewhere.

FAQ

Is it okay to be my own agent?

Yes, if your address and status fit the state's rule.

What address does the agent need?

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.

How do the three-year costs stack up?

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

How official are these figures?

Delaware's fee schedules and forms for state costs; each company's price page for service costs.

Does the state make me use a service?

Not required. What you'd pay a service is for convenience.

Who tops the list in Delaware?

Mainstay Filing is on top because its price doesn't change by state: $149 a year, $149 at renewal; Delaware Registered Agent.ai and DE Registered Agent.org follow.
