Why we put Mainstay Filing first
Here's how we scored it: three-year cost and filings in the price are worth 29% each, and renewal price, state fit and up-front totals split the other 42%. In Texas, filings in the price made the difference.
Mainstay's plan does more: it scans papers served on the company the same business day, free, and the price is the same in all fifty states, with three government letters a year scanned at no charge. Texas Registered Agent.ai costs less, so it's a close race.

What Texas says about the registered agent (via Texas Secretary of State)
Every LLC must name a registered agent with an in-state street address. The address has to be a street address where papers can be handed to the agent during normal business hours. A mailbox service or answering service alone does not qualify. The law: Tex. Bus. Orgs. Code § 5.201.
The Texas Public Information Report + Franchise Tax Report: when and how much
Here's the schedule: the Public Information Report + Franchise Tax Report is due every year in Texas, by May 15. It costs nothing. If you're late, add $50. Reminders from the state go to your registered agent.
Your questions about Texas registered agents
Do I really need a registered agent for a Texas LLC?
You do. Texas won't accept an LLC without a registered agent who has a street address in the state, and that name goes on the public record.
What do Texas registered agents usually cost per year?
Plan on $99 to $149 a year, and each service keeps its price when you renew.
Can I be my own registered agent?
Sometimes, if you meet the state's rules. A Texas resident, including an owner, officer or employee, or an organization registered or authorized in Texas with a business office at the registered office. The company cannot be its own agent, and the agent has to consent.
When do I have to send in the Texas Public Information Report + Franchise Tax Report?
Mark May 15 on your calendar. There is no state charge, and sending it late tacks on $50.
Which registered agents did we review here?
Mainstay Filing ($149 a year), Texas Registered Agent.ai ($99 a year) and TX Registered Agent.org ($99 a year), with our favorite first.
Who is the best registered agent for Texas?
Mainstay Filing, because it's $149 a year and the price doesn't climb at renewal, plus papers served on the company get scanned the same business day for free.
