Which form, and who gets it?
Once the Wyoming Secretary of State, Business Division accepts the Foreign Limited Liability Company Application for Certificate of Authority (FLLC-CertificateAuthority), your LLC is registered.
Include original certificate of existence / good standing no older than 60 days.
Is there a filing that repeats?
The state wants a annual report and license tax later, and it's $60.
Straight from the state, the deadline is first day of your anniversary month.
Why this order?
On jobs the price actually covers (30% of the score), Mainstay Filing wins.
Two tests carry most of the weight: money out the door in three years (35%) and jobs the price actually covers (30%).
With two states in play, a provider that covers every state beat Wyoming Registered Agent.ai.
The last row is our math, not the state's: filing fee, plus the reports in years two and three, plus any minimum tax. If a cost has no fixed amount, like a newspaper notice, it's explained above and left out.
More questions
Do I still need an agent at home?
Yes. Your home state has its own agent rule, and Mainstay Filing can cover both states from one account.
What do the picks cost over three years?
Over three years you're looking at $497 at Mainstay Filing, $397 at Wyoming Registered Agent.ai, $397 at WY Reg Agent.com, before state fees.
Are the fees official?
State fees come from Wyoming's official documents, and service fees come from each company's own price page. Both are dated here.
Do I have to use a service?
No. You can file with the state yourself. A service saves you time and can be your agent, but nothing makes you hire one.
Will a service file it for me?
All of them do, so the service fee's the only difference.
