When You Need to Register as a Foreign LLC

A "foreign LLC" is simply an LLC formed in another state that wants to do business in Tennessee. Before you can legally operate in Tennessee, you must register with the Tennessee Secretary of State and obtain a Certificate of Authority by filing Form SS-4233. For the full picture of ongoing deadlines and official filing links, see our Tennessee LLC compliance hub.

Activities That Require Registration

Tennessee law requires foreign LLC registration if you're "transacting business" in the state. This includes:

Physical presence: Having an office, warehouse, or storefront in Tennessee
Employees: Hiring Tennessee-based employees or contractors
Regular business: Conducting recurring business activities in Tennessee
Contracts: Regularly entering into contracts to be performed in Tennessee
Inventory: Maintaining inventory or stock in Tennessee
Service delivery: Providing services in person within Tennessee

Activities That Do NOT Require Registration

Certain limited activities don't trigger the registration requirement:

Isolated or occasional transactions (not regular business)
Owning real estate in Tennessee (passive ownership)
Maintaining bank accounts in Tennessee
Holding meetings of members or managers in Tennessee
Selling through independent contractors
Conducting business in interstate commerce that passes through Tennessee

Gray Areas: Many situations fall between clearly required and clearly exempt. When in doubt, consult a Tennessee business attorney. The $300 minimum registration fee is usually far less than the risk of operating without it.

Requirements for Foreign LLC Registration

Before filing your Application for Certificate of Authority, gather the following:

Required Documents

Certificate of Existence (or Good Standing)
Obtained from your home state's Secretary of State. By statute (T.C.A. § 48-249-904) it must be dated no more than two months before your Tennessee filing. Cost varies by state ($5-$50).
Application for Certificate of Authority
Tennessee Form SS-4233. Complete it online at tnbear.tn.gov/NewBiz, then file online or print and mail it to the Secretary of State.
Tennessee Registered Agent Designation
Must have a Tennessee registered agent with a physical TN street address. Included in the application form.

Information You'll Need to Provide

LLC's exact legal name (as registered in home state)
State and date of formation
Principal office address
Tennessee registered agent name and address
Names and addresses of all members/managers (depending on management structure)
Brief description of business purpose
Effective date (can be future dated up to 90 days)

Registered Agent Requirements

Your Tennessee registered agent must:

Be a Tennessee resident OR a business entity authorized to do business in Tennessee
Have a physical street address in Tennessee (no PO Boxes)
Be available during normal business hours to accept legal documents
Consent to serve as registered agent

The rules are the same ones that apply to in-state LLCs. For a deeper look, see our guide to Tennessee registered agent requirements, and the ongoing tax side in Tennessee LLC taxes & fees.

Step-by-Step Registration Process

Step 1: Check Name Availability

Search the Tennessee Secretary of State business name database to verify your LLC name is available. If your exact name is taken, you have options:

Register under an assumed name in Tennessee (Form SS-4222, $20)
Modify your name slightly (if allowed by your home state)
Contact the existing business to see if they're still active

Step 2: Obtain Certificate of Existence

Contact your home state's Secretary of State to obtain a Certificate of Existence (also called Certificate of Good Standing). This document confirms your LLC is in good standing in its home state.

Timing Tip: Order this document shortly before you plan to file in Tennessee. It must be dated no more than two months before your Tennessee filing date, or the application will be rejected.

Step 3: Arrange for a Tennessee Registered Agent

If you don't have a Tennessee presence, you'll need to appoint a registered agent:

Professional service: $50-$300/year (recommended for out-of-state owners)
Tennessee resident: A friend, family member, or business contact in TN
Tennessee attorney or accountant: Who can also provide professional services

Step 4: Complete the Application

Fill out the Application for Certificate of Authority (Form SS-4233). You can file online or by mail:

Online: Through the Tennessee SOS Business Services portal
Mail: Send to Tennessee Secretary of State, 312 Rosa L. Parks Avenue, 6th Floor Snodgrass Tower, Nashville, TN 37243

Step 5: Pay the Filing Fee

Submit the filing fee: $50 per member, with a $300 minimum and a $3,000 maximum. Most single-member and small multi-member LLCs pay the $300 minimum. Payment methods:

Online: Credit card or ACH transfer
Mail: Check or money order payable to "Tennessee Secretary of State"

Step 6: Receive Your Certificate of Authority

Once approved, the Tennessee Secretary of State will issue your Certificate of Authority. This document proves your LLC is authorized to transact business in Tennessee.

Keep a Copy: Store your Certificate of Authority with your LLC's important documents. Some banks, landlords, and business partners may request to see it.

Ongoing Compliance Requirements

Once registered, your foreign LLC must meet the same compliance requirements as Tennessee domestic LLCs:

Annual Report

Due date: First day of the fourth month after your fiscal year closes (April 1 for calendar-year LLCs)
Fee: $50 per member, minimum $300, maximum $3,000 (a change of registered agent on the report adds $20)
Missed deadline: Tennessee charges no per-month late fee. Instead, the Secretary of State can administratively dissolve an LLC that fails to file, after which you must reinstate to do business again
Filing method: Online through the TNCaB portal at tncab.tn.gov

The annual report fee matches the structure of the registration fee, so most foreign LLCs continue to pay the $300 minimum each year. For the deadlines, penalties, and reinstatement process in full, see our guides to the Tennessee LLC annual report and Tennessee LLC late filing penalties.

Tennessee Taxes

Foreign LLCs are subject to Tennessee's business taxes:

Franchise Tax: $0.25 per $100 of Tennessee property or net worth attributable to Tennessee (minimum $100)
Excise Tax: 6.5% on net earnings attributable to Tennessee operations
Filing requirement: Must file franchise and excise tax returns even if no tax is due

Tax Note: Unlike many states, Tennessee does not have a personal income tax. However, the franchise and excise taxes apply to LLCs regardless of how they're taxed federally.

Maintain Registered Agent

You must continuously maintain a Tennessee registered agent. If your agent resigns or you need to change agents, file a Statement of Change of Registered Agent/Office (Form SS-4534, $20) with the Secretary of State. Losing your registered agent is itself a ground for administrative dissolution.

Name Availability and Fictitious Names

Name Requirements in Tennessee

Your LLC name must meet Tennessee's naming requirements:

Must include "Limited Liability Company," "LLC," or "L.L.C."
Must be distinguishable from other Tennessee business names
Cannot imply government affiliation
Cannot include restricted words (bank, insurance, etc.) without proper licensing

If Your Name Is Unavailable

If your exact LLC name is already registered in Tennessee, you have three options:

Use an assumed name: Register your LLC under a different name in Tennessee while keeping your legal name in your home state. File an Application for Registration of Assumed Name with the Secretary of State (Form SS-4222, $20) — in Tennessee this is a single state-level filing, not a per-county DBA.
Modify your name: Add distinguishing words like your state abbreviation (e.g., "ABC LLC of Texas" instead of "ABC LLC").
Check if existing name is available: The existing business may be dissolved or inactive. Contact Tennessee SOS to verify.

Tip: Before finalizing your registration, search the Tennessee trademark database and do a general web search to ensure your desired name doesn't infringe on existing businesses, even if it's available with the Secretary of State.

Frequently Asked Questions

How long does it take to register a foreign LLC in Tennessee?

Online filings are typically processed within 2-4 business days. Paper filings submitted by mail take 7-10 business days. Expedited processing is available for an additional fee.

Do I need to form a new LLC in Tennessee or just register my existing one?

You don't need to form a new LLC. Foreign LLC registration (Certificate of Authority) allows your existing LLC to legally operate in Tennessee while maintaining its home state status. Your LLC remains governed by its home state's laws for internal matters.

What triggers the requirement to register as a foreign LLC in Tennessee?

You must register if you're 'transacting business' in Tennessee. This includes having a physical office, employees, or inventory in TN; regularly conducting business meetings in TN; or entering into contracts that will be performed in TN. Isolated transactions or owning real estate alone typically don't trigger registration.

Can I use my existing LLC name in Tennessee?

Only if your name is available and compliant in Tennessee. Search the Tennessee SOS database to check availability. If your name is taken, you can register under an assumed name (Form SS-4222, $20) with the Secretary of State while keeping your original name in your home state.

What happens if I do business in Tennessee without registering?

Operating without registration can result in penalties, inability to use Tennessee courts to enforce contracts, and potential fines. You may also be personally liable for contracts entered into on behalf of an unregistered LLC.

How much does it cost to register a foreign LLC in Tennessee?

The Application for Certificate of Authority (Form SS-4233) costs $50 per member, with a minimum fee of $300 and a maximum of $3,000. A single-member or small multi-member LLC pays the $300 minimum. Add the cost of a home-state certificate of existence (typically $5-$50) and a registered agent if you use a professional service.

Is a foreign LLC subject to Tennessee taxes?

Yes, foreign LLCs doing business in Tennessee are subject to the same taxes as domestic LLCs, including franchise tax (minimum $100, based on net worth) and excise tax (6.5% on net earnings attributable to Tennessee). You must also file the annual report (minimum $300).
