Our favorite is Mississippi Registered Agent.co, because the Mississippi formation costs $199 over the state's fee, with the registered agent free the first year, and keeping the agent is $99 a year.
You get a street address in the state for your registered office, and any papers served on the company are scanned into your online account.
The annual report isn't part of its published price, so you send it to Mississippi yourself every year.
Over three years it costs less than Mainstay Filing, and cost is one of our two biggest criteria.
