How to Start a Business in the USA: Step-by-Step Guide for Entrepreneurs

Launching a company is exciting—but the legal steps can feel like a maze. If you’re searching for how to start a business in the USA, you’re really asking: “What do I do first, what can wait, and how do I avoid expensive mistakes?”

About 80% of new businesses survive their first year, but only around 50% make it to year five according to the Bureau of Labor Statistics. Early legal and structural decisions are a big part of why some companies survive that long—and others don’t.

This guide walks you, step by step, through the essentials: choosing a structure, registering with the state, getting an EIN, licenses, contracts, IP protection, and ongoing compliance. It’s written in plain English and tied directly to the kind of fixed-fee legal support AirCounsel can provide when you’re ready.

What It Really Means To Start A Business

Legally, you “start a business” in the USA when you:

  • Choose a legal structure (for example, LLC or corporation).
  • Register that structure with a state.
  • Get the tax IDs, accounts, and approvals needed to operate.

You can sell as a solo freelancer under your own name without forming an entity. But if you want to:

  • Limit personal liability.
  • Bring on partners or investors.
  • Build a brand you can sell one day.

…you’ll almost always want to form a limited liability company (LLC) or corporation and get your legal foundation right from day one.

Step 1: Clarify Your Idea And Business Model

Before you touch legal paperwork, get clarity on:

  • What you sell: Product, service, or software?
  • Who you serve: Consumers, other businesses, or both?
  • How you make money: One-time payments, subscriptions, retainers, licensing, ads, etc.
  • Where you operate: Online only, in one state, or across multiple states?

These answers drive:

  • Which licenses you’ll need.
  • How you should structure the business.
  • What contracts and policies you’ll rely on.

If you’re still refining your model, you can speak with a lawyer through an online consultation with a US attorney to sanity-check your approach and understand the legal implications.

Step 2: Choose Your Business Structure

Your business structure impacts taxes, paperwork, and liability. The Small Business Administration’s guidance on choosing a business structure is a useful high-level reference.

Common Structures For Startups

  • Sole Proprietorship

    • No separate entity; you and the business are the same for legal and tax purposes.
    • Easiest and cheapest, but no liability shield for your personal assets.

  • Limited Liability Company (LLC)

    • Separates your personal assets from business liabilities (if maintained correctly).
    • Flexible tax options (default pass-through; can elect S corporation taxation in some cases).
    • Simple to manage for most small businesses and online startups.

  • Corporation (C Corp or S Corp)

    • C Corp is standard for venture-backed startups.
    • S Corp is a tax status (not a separate entity type) that can sometimes lower self-employment taxes.
    • More formalities: boards, minutes, stock ledgers, etc.

  • Partnerships (General or Limited)

    • Used when 2+ people go into business together without forming an LLC or corporation.
    • General partners typically have personal liability for business debts.

How To Decide Quickly

Use this as a rough rule of thumb (not a substitute for advice):

  • Solo, service-based, or online business: LLC in your home state is usually a strong default.
  • Planning to raise venture capital: C corporation, usually in Delaware.
  • Side hustle with minimal risk: You can start as a sole proprietor, but an LLC is still often worth it for risk management.

If you want an attorney to walk through options and then handle the filing, AirCounsel’s Entity Formation Services provide state-specific, attorney-guided setup for LLCs and corporations with transparent, fixed fees.

Step 3: Name And Register Your Business

Entrepreneur comparing business name ideas and checking availability online

1. Choose A Legally Available Name

You need to check:

  • State name availability: Most secretary of state websites have a free name search.
  • Trademark conflicts: Even if the state allows your name, a similar registered trademark can block you or later force a rebrand.

A basic DIY approach:

  • Search your state’s business registry.
  • Search the USPTO database for similar marks.
  • Google the name plus your industry.

To de-risk this, consider a professional trademark search by a US attorney before you spend real money on branding and domains.

2. Register With Your State

To formally create an LLC or corporation, you typically:

  • File Articles of Organization (LLC) or Articles/Certificate of Incorporation (corporation) with a state.
  • Appoint a registered agent (a person or company that can receive legal documents).
  • Pay a state filing fee (often $50–$400 depending on the state and entity type).

After approval, the state will issue a formation certificate or stamped documents confirming your entity exists.

3. Consider “DBAs” Or Trade Names

If you want to operate under a different public-facing name than your legal entity name (for example, “Sunrise Apps LLC” doing business as “TaskWave”), you may need to file a DBA (doing business as) or fictitious business name at:

  • The state level, and/or
  • The county/city level (rules vary by state).

Your state’s business portal will explain where DBAs are filed and whether they’re required.

Step 4: Get Your EIN, Bank Account, And Tax Setup

1. Apply For An EIN (Employer Identification Number)

An EIN is like a Social Security Number for your business. You generally need it to:

  • Open a business bank account.
  • Hire employees.
  • Work with many vendors and payment processors.

You can usually get an EIN from the IRS online in minutes through the official EIN application portal. There is no filing fee when you apply directly with the IRS.

2. Open A Dedicated Business Bank Account

Mixing personal and business money is one of the fastest ways to “pierce the corporate veil” and lose liability protection.

Most banks will ask for:

  • Your formation documents.
  • Your EIN.
  • Ownership information (and in some cases beneficial owner details).

Open both:

  • A checking account for day-to-day operations.
  • (Optionally) a savings or tax reserve account to hold sales tax and income tax set-asides.

3. Understand Your Tax Obligations

At a minimum, think about:

  • Federal income tax: Based on your entity type and elections.
  • Self-employment or payroll taxes: Especially for owner-operators and employees.
  • State income, franchise, and/or gross receipts taxes: Varies widely by state.
  • Sales tax: If you sell taxable goods or services.

An accountant plus a business attorney is often the best combination for designing your tax + entity strategy early on.

Step 5: Licenses, Permits, And Local Approvals

Your exact requirements depend heavily on what you do and where you operate, but common categories include:

  • General business license: Many cities/counties require this for any business operating in their jurisdiction.
  • Professional or industry licenses: For example, healthcare, law, construction, real estate, financial services.
  • Sales tax permits: Required in most states if you sell taxable goods or services.
  • Zoning and home-based business permits: If you operate from a physical location or your home.

The SBA’s guide on licenses and permits is a good starting checklist, but you’ll still need to check with your state and city.

If your business is regulated (healthcare, food, childcare, etc.), getting legal support early can save months of delay and missteps.

Step 6: Protect Your Brand And Intellectual Property

Early IP decisions can determine how defensible—and valuable—your business becomes.

1. Trademarks (Brand Names, Logos, Slogans)

Trademarks protect your brand identifiers (names, logos, taglines) for specific goods/services.

  • A registered trademark with the USPTO gives you stronger national rights.
  • Many investors and partners treat real trademarks as a sign of a serious business.

The USPTO’s trademark basics explain the concepts, but the process and wording are technical. AirCounsel offers:

2. Copyrights And IP Ownership

  • Code, designs, content, photos, and videos are usually protected by copyright.
  • If contractors or employees create IP for you, you need written IP assignment or “work made for hire” language to ensure the company owns it.

For one-off transfers (for example, acquiring code or a brand), a custom IP Assignment Agreement helps keep ownership clean and enforceable.

3. Patents (If Applicable)

If you’re developing a novel product or technology, talk with a registered patent attorney early to preserve your ability to file.

Step 7: Draft The Contracts Your Business Runs On

Verbal deals and random templates are a common way otherwise-solid businesses get into trouble.

Core contracts most startups should consider early:

If you already have draft contracts, a review of your contract or legal document can spot red flags before you sign or deploy them.

Step 8: Stay Compliant After You Launch

Starting is just the beginning. Staying compliant reduces risk and keeps your entity in good standing.

Key ongoing obligations often include:

  • Annual reports and fees
    Many states require an annual or biennial report plus a fee for LLCs and corporations.

  • Registered agent updates
    If you change your agent or their address, you usually must update filings.

  • Taxes
    Federal, state, and local tax filings (income, payroll, sales/use, franchise, etc.).

  • Corporate governance
    Corporations in particular should keep basic minutes, resolutions, and stock records.

  • New federal beneficial ownership reporting (Corporate Transparency Act)
    Most smaller entities formed in or after 2024 must report their true individual owners to FinCEN under the Corporate Transparency Act. The official FinCEN BOI resource page explains who must file, what to report, and deadlines.

Many founders use an ongoing legal membership, such as AirCounsel’s All-Access Legal Membership, to get quick answers on compliance questions as they grow.

Typical Costs And Timelines To Start A Business

Every business is different, but here’s a ballpark for a lean, legally sound launch in the USA.

ItemTypical Cost RangeTypical TimelineNotes
State formation filing (LLC or corporation)$50–$400 (state fee)1–10 business daysExpedited options can be same or next day in some states.
Registered agent (if not you)$100–$300/yearSame dayRequired if you don’t have a physical address in the state or want privacy.
EIN from IRS$0Same day onlineApply directly at IRS; avoid paid “EIN services” that just use the same free form.
Basic business licenses/permits$50–$500+1 day–6 weeksHighly state/city/industry-dependent.
Core contract drafting (per key agreement)$500–$900+2–5 business daysVaries with complexity; AirCounsel offers fixed pricing for many agreements.
Trademark search + filing (per mark)$60–$995+ plus USPTO feesSearch: 2–3 days; Filing: 1–3 daysRegistration process itself takes months, but you’re protected from filing date.

A realistic lightweight legal budget for many online or service-based startups is often in the $1,000–$3,000 range to get structure, core contracts, and basic brand protection in place—significant, but modest compared to the cost of a single major dispute.

Common Mistakes When Starting A Business

  • Delaying entity formation
    Operating as a sole proprietor “just for now” while signing leases, big contracts, or taking on risk can expose your personal assets.

  • Using random templates found online
    Templates often don’t match your state law, your business model, or current regulations.

  • Ignoring ownership splits and decision-making
    If there is more than one founder, you need clear agreements about who owns what, who decides what, and what happens if someone leaves.

  • Failing to separate business and personal finances
    Paying personal expenses from the business account (or vice versa) can undermine your liability shield.

  • Skipping IP ownership language with contractors
    Without clear assignment clauses, your designer or developer may own key IP, not your company.

  • Assuming “I’m small, so rules don’t apply to me”
    Local licensing, taxes, and now federal ownership reporting can still apply even to micro-businesses.

  • Document everything from day 1
    Keep a folder (digital is fine) with formation documents, EIN confirmation, contracts, and licenses.

  • Pick one “home state” and stick with it—at least initially
    Form where you actually operate unless you have a specific reason (like institutional investors requiring Delaware).

  • Use written contracts even with friends and family
    Clarity now preserves relationships later.

  • Budget for legal as a line item, not an emergency expense
    Treat it like software or marketing—part of doing business, not an optional luxury.

  • Get a tailored LLC Operating Agreement if you choose an LLC
    A custom LLC Operating Agreement sets rules for ownership, voting, profits, and exits so you’re not relying solely on default state law.

  • Ask focused questions early instead of fixing big problems later
    If you’re unsure about a step, a short ask-a-lawyer email question can prevent expensive rework.

Frequently Asked Questions

What is the easiest business structure to start?

The simplest structure is a sole proprietorship, because you don’t have to file formation documents—you just start doing business under your own name. However, most entrepreneurs choose an LLC instead because it’s still relatively simple while offering personal liability protection and more credibility with banks, partners, and clients.

Do I need a lawyer to start a business?

Legally, you can file most formation documents yourself, but a lawyer helps you choose the right structure, avoid state-specific pitfalls, design ownership terms, and prepare contracts that actually protect you. Many founders find that limited, targeted legal help at the start saves far more in avoided disputes and rework later.

How much does it cost to start a business in the USA?

It depends heavily on your state and industry, but many lean startups can handle basic legal setup for $1,000–$3,000, plus state filing fees (often $50–$400) and any license fees. High-regulation industries (healthcare, finance, food, franchises) may have additional legal and compliance costs.

What licenses do I need for my startup?

Requirements are state- and city-specific. Common examples include a general business license, sales tax permit, and profession-specific licenses (for example, contractors, real estate, medical, childcare). Start with your state’s business portal and local city/county government website, then confirm details with a lawyer if you’re in a regulated space.

Do I need an LLC for a side hustle?

Not always—but it’s often a good idea. If your side hustle has meaningful risk (clients, physical products, events, employees, etc.), an LLC can help shield your personal assets. If you’re testing a very low-risk concept, you can start as a sole proprietor, then convert to an LLC once revenue and risk increase.

When should I think about trademarks?

Consider a trademark search before you invest heavily in branding, domains, and marketing. If your name clearly conflicts with an existing mark, it’s cheaper and safer to rebrand early. Once you’re confident in the name, filing a trademark application helps secure your rights as you grow.
