How the order came together
LLC Review Desk gives three-year cost 29% and filings in the price 29%, then divides 42% among renewal price, state fit and up-front totals. For Utah, it came down to three-year cost.
UT Registered Agent.org comes to $297 over three years, which is $150 less than Mainstay Filing. If you only need an agent in Utah, fifty-state reach doesn't help much, so the lower yearly price won.

What Utah says about the registered agent (via Utah Secretary of State)
Every LLC must name a registered agent with an in-state street address. The address has to be an actual street address or rural route box number in Utah. A P.O. box can follow the street address but cannot replace it. The law: Utah Code § 16-17-203.
The Utah Annual Report/Renewal: when and how much
Here's the schedule: the Annual Report/Renewal is due every year in Utah, by last day of the entity's anniversary month. It costs $18. If you're late, add $10. Reminders from the state go to your registered agent.
Your questions about Utah registered agents
Do I really need a registered agent for an Utah LLC?
You do. Utah 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 Utah 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 commercial registered agent listed with the state, a noncommercial agent (an individual or entity), or the holder of a named position in the company.
When do I have to send in the Utah Annual Report/Renewal?
Mark last day of the entity's anniversary month on your calendar. The state's charge is $18, and sending it late tacks on $10.
