What Delaware requires of a registered agent (official rules)
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. Source: 6 Del. C. § 18-104.
Annual LLC Tax: what it costs
Expect the Annual LLC Tax every year, due annual alternative-entity tax due on or before June 1; the state charges $400. Late filing costs $200. Notices about it arrive at your registered agent.
