We took each price from the company's own pages on November 12, 2026. Tennessee's own fees stay the same no matter which agent you choose.
How the order came together
Two things count most to us, three-year cost and filings in the price, at 29% each. Renewal price, state fit and up-front totals share 42%, and Tennessee came down to filings in the price.
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. Tennessee Registered Agent.co costs less, so it's a close race.

What Tennessee says about the registered agent (via Tennessee Secretary of State)
Every LLC must name a registered agent with an in-state street address. The address has to be a Tennessee street address, with the county. P.O. boxes are not accepted. The law: Tenn. Code Ann. § 48-249-109.
The Tennessee annual report: when and how much
Here's the schedule: the annual report is due every year in Tennessee, by on or before the first day of the fourth month following the close of the LLC's fiscal year. It costs $300. Reminders from the state go to your registered agent.
Your questions about Tennessee registered agents
Do I really need a registered agent for a Tennessee LLC?
You do. Tennessee 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 Tennessee 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 Tennessee resident, or a business entity formed in Tennessee or authorized there with an office at the registered office street address.
When do I have to send in the Tennessee annual report?
Mark on or before the first day of the fourth month following the close of the LLC's fiscal year on your calendar. The state's charge is $300.
