Introduction

Starting a company is exciting, but let’s be honest—the legal side can feel like a maze of paperwork, rules, and decisions no one warned you about. The good news? It doesn’t have to be that way. With a clear roadmap and the right tools, you can move from idea to official company without the stress. This guide breaks down the essentials so you can launch your startup legally, confidently, and without wasting time.

Step 1: Choose the Right Legal Structure

Before you can officially start your business, you’ll need to decide on a legal structure. This choice affects your taxes, liability, paperwork, and funding opportunities. The most common options are:

  • Sole Proprietorship: Easiest to set up, but offers no personal liability protection.

  • Partnership: Ideal for two or more founders. Can be general or limited.

  • Limited Liability Company (LLC): A flexible option that offers liability protection and pass-through taxation.

  • Corporation (C-Corp or S-Corp): Preferred by startups aiming to raise venture capital. More complex but can scale well.

Each has trade-offs, so consider talking to a startup-friendly attorney or using a trusted formation service to make the best call.

Step 2: Register Your Business Name

If you’re not operating under your own name, you’ll likely need to register a "Doing Business As" (DBA) name. Make sure your name is available in your state and doesn't infringe on existing trademarks.

You should also check for domain name availability and reserve your social media handles to keep your branding consistent across platforms.

Step 3: File Formation Documents

Depending on your structure, you’ll need to file specific documents with your state:

  • LLC: Articles of Organization

  • Corporation: Articles of Incorporation

These documents formally establish your company. You’ll also pay a filing fee, which varies by state.

Step 4: Get an EIN (Employer Identification Number)

An EIN is like a Social Security number for your business. You’ll need it to open a business bank account, hire employees, and file taxes. You can get one for free from the IRS website.

Step 5: Set Up Business Bank Accounts and Financial Tools

Open a business checking account and consider tools for bookkeeping, invoicing, and expense tracking. Keeping your business finances separate from your personal ones is critical for both tax reasons and legal protection.

Step 6: Understand Ongoing Compliance Requirements

Once your company is formed, you’ll need to stay in good standing by meeting ongoing requirements like:

  • Annual reports

  • Franchise taxes

  • State licenses and permits

Failing to meet these can lead to fines or even administrative dissolution. Setting up reminders or using a compliance platform can help you stay on track.
