Tennessee charges $20 to change your registered agent, and your old agent can quit the same day.

Yes. T.C.A. §48-249-109(a) says each domestic and foreign LLC shall continuously maintain in Tennessee a registered office and a registered agent who keeps an office at the same street address. If the agent resigns or can't do the job, §48-249-109(b) says the LLC must promptly designate another one. The articles of organization name the first agent, and every annual report repeats it.

An individual who lives in Tennessee, or a domestic corporation, nonprofit, LLC, general partnership, limited partnership, or registered LLP, or a foreign version of any of those that is authorized to do business in Tennessee (§48-249-109(a)(2)). A member who lives in Tennessee can serve. Unlike some states on this desk, the list includes domestic LLCs, but we would not plan on an LLC serving as its own agent, since the agent is the one who receives papers for it.

No PO box. The Secretary of State's business FAQ says the registered office must be a physical Tennessee address and cannot be a post office box, route number, or box number alone, and the articles form says a PO box is not acceptable for the agent address. The statute also requires the agent's business office and the registered office to share the same street address. A mailbox service at a street address is your agent only if it is actually named on file and fits the who-may-serve list.

$20 on the Statement of Change of Registered Agent by Entity (form SS-4534), under §48-249-1007(a)(9). You can file it online, by mail, or in person; online card payments add a convenience fee, and print-and-mail avoids it. The other route is the annual report: §48-249-1017(b) treats an annual report that changes the agent as the statement of change, and §48-249-1007(d) adds $20 to the report fee. Either way the state charge is $20. Northwest says it files the change for new clients and pays the state filing fee when it is appointed.

On or before the first day of the fourth month after the LLC's fiscal year ends (§48-249-1017(c)). For a calendar-year LLC that is April 1. The fee is $50 per member with a $300 minimum and a $3,000 maximum (§48-249-1007(d)), so any LLC with one to six members pays $300. The online filing window opens on the first day of the fiscal-year-end month, and the state's instructions say delinquent reports can be filed within four months after the due date. Tennessee franchise and excise taxes are a separate Department of Revenue bill and are not on this page.

The agent files a statement of resignation ($20) and certifies that it mailed notice to your principal executive office by certified mail (§48-249-111(a)). Since a 2025 amendment, the appointment ends on the date the statement is filed (§48-249-111(b)). There is no grace period on the agent side. Your clock is in §48-249-604: two months without an agent, or two months without telling the Secretary of State about the change, is a ground for administrative dissolution. In the meantime §48-249-112(b) makes the Secretary of State your agent, and it forwards papers to the registered or principal office on file.

If the report is more than two months late, §48-249-604(1) lets the Secretary of State start an administrative dissolution. After it sends notice, the LLC has two months to fix the problem (§48-249-605(b)). After that it is dissolved and can only wind up. Reinstatement costs $70 on form SS-9410, the ground has to be eliminated (for a missed report, that means filing it at $300 or more), and the state requires a Department of Revenue tax clearance. Reinstatement relates back to the dissolution date (§48-249-606(c)).
