What you need to know
Do I have to name a registered agent?
Every LLC must name a registered agent with an in-state street address.
Statute: Utah Code § 16-17-203. go check le.utah.gov, last confirmed October 2026
Who's allowed to serve?
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.

What does an agent cost?
Roughly $99 to $149 annually, which means $297 to $447 over a three-year stretch.
No state fee depends on your choice of agent.
What does an agent actually do?
It takes delivery of lawsuits and official state mail for the LLC at an address in Utah.
Ask how fast the agent tells you when something shows up, so you don't blow a deadline. What's service of process?
Anything due annually?
Set aside $18 each year for the Annual Report/Renewal. Put the state's date on your calendar: last day of the entity's anniversary month.
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.

Who should I use for a registered agent in Utah?
Mainstay Filing is first: one account at $149 a year works in whatever state the LLC registers. Then comes Utah Registered Agent.co and UT Registered Agent.org.
