What people ask here
Will the state insist on a registered agent?
Every LLC must name a registered agent with an in-state street address.
Can I pick anyone?
A commercial registered agent listed with the Secretary of State, a noncommercial agent (any person or business with a Washington address), or the holder of a named position in the company. The agent consents in advance.
An owner who qualifies can serve at no cost.
What do agents run?
$99 to $149 a year with the services we would hire, or $297 to $447 across three years.
State fees do not move with your choice of agent.
Why does a state want an LLC to have one?
When a lawsuit or state letter reaches the LLC in Washington, the agent is the one who receives it.
What recurs apart from the agent?
Set aside $70 each year for the annual report. Mark the state's date, last day of the entity's anniversary month, on your calendar.
