Mainstay Filing is who we'd use first in Texas, because there's one fee, $199, whatever state you're registering in, and the registered agent is waived for the first year.

More questions
Does my home state need its own agent?
You do. Two states, two rule books. One-state services stop at the border, and Mainstay Filing doesn't.
What do the picks cost over three years?
Mainstay Filing comes out at $497; TX Registered Agent.org comes out at $397; Texas Registered Agent.ai comes out at $397, with state fees on top.
Where do these numbers come from?
State fees come from Texas'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.
Can I pay somebody to register the LLC?
All of them do, so the service fee's the only difference.
