How the card was marked

Points here: 25% for cost across three years, 25% for coverage of the price and 50% across renewal terms, state-by-state fit and pricing clarity. Delaware came down to cost across three years.

Delaware Registered Agent.ai tallies $297 across three years, $150 below Mainstay Filing. If Delaware is the only state, fifty-state coverage adds little, and the lower yearly price takes the points.

Every criterion and weight appears on How we rank.

What Delaware Secretary of State requires of a Delaware registered agent (official)

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. Statute: 6 Del. C. § 18-104.

The Delaware Annual LLC Tax: fee, due date and your agent

Delaware LLCs file the Annual LLC Tax every year. The fee is $400 and the date is annual alternative-entity tax due on or before June 1. Filing late means $200 more. The state sends related notices to your registered agent.
