Starting a small business in the United States is an exciting venture, but it involves more than just having a great idea. To ensure your business is legally recognized and protected, you must go through the proper channels to register it. This process can vary slightly depending on your state and the nature of your business, but there are general steps that apply to most situations.
TLDR (Too Long, Didn’t Read)
To legally register a small business in the U.S., you’ll need to choose a business structure, register your business name, get federal and state tax IDs, and comply with licensing and permit requirements. The process typically starts at the state level and involves submitting forms and fees. Depending on the industry and location, some businesses may need specialized registrations. Start by researching your state’s Small Business Administration (SBA) resources to streamline the process.
1. Decide on a Business Structure
Your business structure determines many legal and tax obligations, so it’s crucial to choose the best one for your goals. Below are the main types of business structures recognized in the U.S.:
- Sole Proprietorship: Simplest form, no separate legal entity. Taxes are filed under your personal tax return.
- Partnership: Owned by two or more people. Shared profits, liabilities, and legal responsibilities.
- Limited Liability Company (LLC): Offers personal liability protection and flexible tax treatment.
- Corporation (C-Corp or S-Corp): More complex, better for larger firms or those seeking investment.
Each structure comes with pros and cons regarding liability, taxation, and administrative requirements. Consulting a business attorney or accountant can help make the right decision for your particular situation.
2. Register Your Business Name
Once you’ve chosen a structure, the next step is registering your business name, also known as your “Doing Business As” (DBA) name—unless you plan to operate under your own legal name (as is sometimes the case with sole proprietorships).
There are three levels at which you may need to register your business name:
- Entity Name: Register with your state to protect your business at the state level.
- DBA Name: Register with your state, county, or city if you’re operating under a different name than your legal name.
- Trademark: Register federally with the U.S. Patent and Trademark Office (USPTO) for nationwide brand protection.
Before registering, search your desired business name in your state’s business registry and the USPTO database to ensure it’s not already in use.
3. Obtain a Federal Employer Identification Number (EIN)
An Employer Identification Number (EIN) is a federal tax ID managed by the Internal Revenue Service (IRS). It’s required if you:
- Have employees
- Operate as an LLC, partnership, or corporation
- Withhold taxes on income (excluding wages) paid to a non-resident alien
- Have a Keogh plan
- Are involved with certain organizations, such as trusts or estates
Even if you’re not required to have an EIN, many banks require one to open a business bank account. Applying is free through the IRS website.
4. Register With Your State and Local Governments
Most businesses need to register with their state and possibly local governments to legally operate. This typically includes:
- State Tax Registration: Particularly important if your business sells goods or services subject to sales tax.
- State-Specific Licenses and Permits: Requirements differ, but many industries including food service, healthcare, and construction need permits.
- Zoning and Land Use Permits: If operating from a physical location, your city or county may require zoning approval.

Each state’s process is different. Visit your Secretary of State’s website to learn the exact requirements in your jurisdiction. If you’re expanding to multiple states, you may need to register in each one individually, a process called foreign qualification.
5. Open a Business Bank Account
Once your federal and state registrations are complete, you should open a separate business bank account. This is essential for:
- Maintaining limited liability protection
- Organizing income and expenses for accounting
- Accepting payments and paying vendors
To open a business bank account, most banks require your EIN, formation documents, business license, and ownership agreements. Keeping your personal and business finances separate is not just good practice — it also safeguards your legal protections.
6. Apply for Required Licenses and Permits
Your specific business activities may require federal, state, or local licenses and permits. Examples include:
- Federal Licenses: Needed for businesses in regulated sectors like alcohol, firearms, and transportation.
- State Licenses: Varies by state and industry; examples include cosmetology, child care, and food safety certifications.
- Local Permits: Including health permits, signage approval, and fire inspections depending on location and structure.
Use the U.S. Small Business Administration’s license and permits tool to identify requirements specific to your location and industry.
7. Understand Ongoing Compliance Requirements
Registering your business isn’t a one-time event. Most states require:
- Annual Reports or Statements of Information
- Franchise Taxes or annual business entity taxes
- Timely Renewal of Licenses
Failure to comply can lead to administrative dissolution of your business or fines. Staying organized and using a compliance calendar can help you avoid unnecessary penalties and maintain good legal standing.
8. Consider Intellectual Property Protection
If your business uses original content, slogans, product designs, or software, consider applying for:
- Trademarks: Protect business names, logos, and slogans
- Copyrights: Secures rights to literature, music, software, and more
- Patents: Applies to new inventions or product designs
Intellectual property registration is handled federally through agencies like the USPTO or the U.S. Copyright Office.
9. Seek Professional Help if Needed
Navigating legal registration can be complex, especially if you’re operating in a regulated industry or plan to hire employees. Consider consulting a:
- Business attorney for legal structure and contract advice
- Certified Public Accountant (CPA) for tax planning
- Business formation service if you prefer a guided approach
Conclusion
Registering your small business legally in the U.S. is a vital step for protecting your business, staying compliant, and setting the stage for long-term success. Though the process may seem overwhelming at first, breaking it down into manageable steps ensures you stay organized and legally sound. Be sure to regularly review your state and local government websites, as regulations and requirements evolve over time. With careful planning, good documentation, and professional guidance when necessary, your business can begin its journey on solid legal footing.
