Thinking of expanding your business to another U.S. state? Before you set up shop, hire employees, or sign contracts, there’s one crucial legal step you can’t afford to miss: obtaining a Certificate of Authority (COA).

In this post, we’ll break down everything you need to know about this essential document—what it is, why it matters, and how to get one.


✅ What Is a Certificate of Authority?

A Certificate of Authority is a state-issued permit that allows a business formed in one U.S. state (the “home state”) to legally do business in another state.

It’s often required for:

Example: A business formed in Delaware must apply for a COA to legally operate in Texas.


🚨 Why Is It Necessary?

Doing business in a state without proper authorization can lead to serious consequences. Here’s why the COA is critical:

1. Legal Compliance

Most states legally require foreign businesses to register. Failure to do so = fines + penalties.

2. Protecting Your Rights

Without a COA, your business may not be able to enter contracts or sue in that state’s courts.

3. Access to Resources

Banks, vendors, and government agencies often won’t work with unregistered businesses.

4. Credibility & Transparency

Being registered builds trust with clients, partners, and investors.


🧭 What Counts as “Doing Business”?

Not every interaction counts. But here are common triggers that require you to obtain a Certificate of Authority:

✅ Opening an office or warehouse
✅ Hiring employees or sales reps
✅ Owning or leasing property
✅ Conducting in-person services
✅ Bidding on state contracts

Activities That May Not Require It:

❌ Holding bank accounts
❌ Working with independent contractors
❌ Selling online without physical presence
❌ Attending a one-time conference

Pro Tip: Each state defines “doing business” differently. When in doubt, consult a compliance expert like Complycove.


🕒 When Should You Apply?

Before you do anything in the new state—ideally before hiring or signing contracts. Applying late can lead to:

⚠️ Late penalties
⚠️ Retroactive taxes
⚠️ Voided contracts
⚠️ Legal restrictions


📝 How to Get a Certificate of Authority

The process is different in every state but usually follows these 3 steps:

1. Prepare Your Docs

You’ll need:

2. File the Application

Submit forms to the Secretary of State (or similar office) and pay filing fees.

3. Wait for Approval

Most COAs are processed in 1–2 weeks. Some states offer expedited service for a fee.


⚖️ What Happens If You Don’t?

Here’s what you risk by skipping this step:

🚫 Daily financial penalties
🚫 Loss of legal standing
🚫 Voided contracts
🚫 Lawsuits or back taxes
🚫 Inability to sue in court

Example: In California, operating without a COA can lead to fines of $2,000 or more.
