- Licenses and permits vary by industry, location, and activity — check all three levels of government.
- Keeping registration documents organized from day one prevents compliance issues later.
Why Formal Registration Matters
Starting a business without registering it properly is a common shortcut that creates real problems down the road. Operating informally may seem fine when you're small, but it can expose you to personal liability, block you from opening a business bank account, and make it impossible to bid on contracts or apply for financing.
Formal registration establishes your business as a recognized legal entity, sets up your tax obligations correctly, and signals to clients, suppliers, and lenders that you're operating legitimately. If you're still weighing your options, the foundational overview for first-time business owners covers the broader picture before you commit to a structure.
The exact process depends on two things: where you're operating and what legal structure you choose. Getting clear on both before you start filling out forms will save you from redoing steps.
Step 1: Choose Your Legal Structure
Before you can register anything, you need to decide how your business will be legally structured. The most common options for small businesses in the US are:
- Sole proprietorship — the simplest structure; you and the business are legally the same entity.
- Partnership — two or more people sharing ownership; general and limited partnership variations exist.
- Limited Liability Company (LLC) — a hybrid structure offering personal liability protection with flexible tax treatment.
- Corporation (S-Corp or C-Corp) — a more complex structure with stronger liability separation, suited to businesses planning to raise investment or scale significantly.
Each structure carries different tax obligations, liability exposure, and registration requirements. The plain-language breakdown of sole trader vs. limited company structures is a useful reference if you're undecided. Consulting a licensed accountant or business attorney before choosing is worth the cost — this decision affects your taxes and personal liability for years.
Register Your Business Name
If you're operating under a name other than your own legal name, you'll typically need to file a DBA (Doing Business As) — also called a fictitious name or trade name — with your county or state. LLCs and corporations register their name when they file their formation documents, so a separate DBA is usually only needed if they operate under a different brand name.
Before filing, search your state's business name database to confirm the name isn't already taken. Many states have a free online search tool for this.
File Formation Documents With Your State
If you're forming an LLC or corporation, you'll need to file formal documents with your state's business registration office — usually the Secretary of State. For an LLC, this is called Articles of Organization. For a corporation, it's Articles of Incorporation.
Sole proprietors and general partnerships typically do not file formation documents at the state level — their registration requirement is usually just the DBA, if applicable.
Filing fees vary by state, generally ranging from around $50 to a few hundred dollars. Processing times range from same-day (with expedited fees) to several weeks depending on the state.
Obtain an Employer Identification Number (EIN)
An Employer Identification Number (EIN) is a federal tax ID issued by the IRS. You'll need one if you plan to hire employees, open a business bank account, or operate as an LLC, partnership, or corporation. Sole proprietors with no employees can sometimes use their Social Security Number instead, but an EIN keeps your personal and business finances clearly separated.
Applying for an EIN is free through the IRS website and the number is issued immediately upon completing the online application during business hours.
Register for State and Local Taxes
Depending on your state and what you sell, you may need to register separately for state income tax withholding (if you have employees) and sales tax (if you sell taxable goods or certain services). Not all states have a sales tax or income tax, so requirements vary.
Register through your state's Department of Revenue or equivalent agency. Some states bundle this with the initial business registration; others require a separate application.
Obtain Required Licenses and Permits
Most businesses need at least one license or permit to operate legally. Requirements come from three levels:
- Federal: Required for regulated industries such as firearms, alcohol, aviation, or agriculture.
- State: Professional licenses (contractors, accountants, real estate agents, healthcare workers), general business licenses, and industry-specific permits.
- Local: City or county business licenses, zoning permits, health permits, and signage permits.
The SBA's website and your local Small Business Development Center (SBDC) are reliable starting points for identifying which licenses apply to your specific business and location.
Common Pitfalls and Ongoing Obligations
Registration is not a one-time event. Once your business is live, you'll have ongoing filing requirements — annual reports to the state, renewal of licenses, quarterly or annual tax filings, and updates whenever your address, ownership, or business activities change.
Missing Annual Filings Can Cost You
If you're operating from home, your obligations may extend further than you expect. The guide to running a business from home covers what changes in terms of tax, insurance, and zoning when your home doubles as your workplace.
