How to Start a Business: The Ultimate Guide

Starting a business feels overwhelming when you’re staring at a blank Google search. Between choosing a business structure, filing paperwork, getting tax IDs, and figuring out what you actually need versus what sounds important, it’s easy to get lost in the weeds.

This guide walks you through exactly how to start a business, step by step. We’ll cover the essential decisions you need to make, the paperwork you actually need to file, and what it really costs. No fluff, no generic advice about “following your passion.”

After reading this (takes about 8 minutes), you’ll know exactly what to do first, what can wait, and how to avoid the mistakes that cost new business owners hundreds or thousands of dollars.

What You Need to Know First

Starting a business legally means creating a separate business entity — usually an LLC (Limited Liability Company) or corporation. This gives your business its own legal identity, separate from you personally.

Think of it like getting a driver’s license for your business. Without it, you’re operating illegally. With it, you can open business bank accounts, sign contracts, hire employees, and protect your personal assets if something goes wrong.

Who This Guide Is For

This guide works best if you’re:

A freelancer or consultant ready to formalize your business (maybe you’re billing $50K+ and want liability protection)
Starting a small business like a restaurant, retail store, or service company
Launching a tech startup that needs to raise money or hire employees
Running any business where customers, contracts, or lawsuits could put your personal assets at risk

Common Myths About Starting a Business

Myth 1: “I need a business plan before I can legally start a business.”
Reality: You need zero business planning to file your paperwork. A solid plan helps you succeed, but it’s not legally required.

Myth 2: “LLCs are always better than corporations.”
Reality: It depends. LLCs offer simpler taxes and management. Corporations work better if you plan to raise investment money or issue stock options.

Myth 3: “I have to file in the state where I live.”
Reality: You can incorporate anywhere. Delaware and Wyoming are popular for business-friendly laws and lower costs.

When This Doesn’t Apply

Skip the formal business entity if you’re:

Testing a business idea with less than $10K in annual revenue
Working as an employee or contractor with no liability risks
Running a simple side hustle that doesn’t need business banking or contracts

You can always formalize later when your situation changes.

How to Start a Business — Step by Step

What to Have Ready Before You Start

Your business name (and 2-3 backup options)
The state where you want to file
A registered agent address (more on this below)
Your personal information for filing paperwork

Step 1: Choose Your Business Structure (15 minutes)

Pick between these two main options:

LLC (Limited Liability Company): Best for most small businesses. Simpler taxes, flexible management, protects your personal assets. You pay business income taxes on your personal tax return.

Corporation: Better if you plan to raise investment, issue stock options, or need specific tax advantages. More complex setup and ongoing requirements.

For most people reading this guide, LLC is the right choice. You can always convert to a corporation later.

Step 2: Choose Your State (10 minutes)

You can file in any state, regardless of where you live or operate.

File in your home state if:

You’ll have employees there
You’ll have a physical office or storefront there
You want to keep things simple

Consider Delaware or Wyoming if:

You plan to raise investment money (Delaware)
You want maximum privacy and low ongoing costs (Wyoming)
You don’t plan to have employees or physical locations

Filing out-of-state means you’ll likely need to register as a “foreign entity” in your home state later. This adds complexity but isn’t necessarily a deal-breaker.

Step 3: Check Name Availability (5 minutes)

Search your chosen state’s business database to make sure your name isn’t taken. Every state has a free online search tool.

Your LLC name must end with “LLC” or “Limited Liability Company.” Corporation names need “Inc.,” “Corp.,” or “Corporation.”

Don’t worry about domain names or trademarks yet. Handle the basic legal entity first.

Step 4: Get a Registered Agent (Immediate)

Every business needs a registered agent — someone with a physical address in your filing state who can receive legal documents during business hours.

You can be your own registered agent if you live in the filing state and don’t mind your address being public record. Most people hire a registered agent service for $100-200 per year for privacy and reliability.

Step 5: File Your Formation Documents (Same day online)

For LLCs, you’ll file “Articles of Organization.” For corporations, it’s “Articles of Incorporation.”

This document includes:

Your business name
Registered agent information
Basic business purpose (usually “any lawful business activity”)
Member/owner information (requirements vary by state)

Most states let you file online. Processing takes 1-5 business days for standard filing, or same-day for expedited processing (costs extra).

Step 6: Get Your EIN (10 minutes)

An EIN (Employer Identification Number) is your business tax ID. You need this to open business bank accounts and file taxes.

Apply directly through the IRS website for free. It takes about 10 minutes and you get your EIN immediately. Never pay a third-party service for this.

Step 7: Create Your Operating Agreement (LLC) or Bylaws (Corporation)

This internal document outlines how your business operates — ownership percentages, decision-making processes, what happens if someone wants to leave.

Even single-member LLCs should have an operating agreement. It helps maintain the legal separation between you and your business.

You can find templates online, but consider having an attorney review it if your situation is complex or involves multiple owners.

What It Costs

State Filing Fees

Most states: $100-300
Expensive states (like California): $70 filing fee + $800 annual franchise tax
Cheap states (like Wyoming): $100 total

Formation Service Options

DIY Filing: Just the state filing fee. Takes more time and research, but totally doable for simple situations.

Formation Services: $200-500 total including state fees. They handle the paperwork and often include registered agent service for the first year. Popular options include ZenBusiness, Northwest Registered Agent, and Incfile.

Attorney Filing: $1,000-3,000+ including fees. Worth it for complex ownership structures or businesses with significant legal considerations.

Ongoing Costs to Expect

Registered agent: $100-200 annually
Annual state reports: $10-300 depending on state
Business banking: $10-50 monthly
Accounting software: $15-50 monthly

Bottom Line: Most people spend $300-800 to get their business legally formed and running, then $200-500 annually in ongoing state requirements.

Mistakes That Cost People Money

1. Paying for “Premium” Formation Packages

Formation companies love selling $500-1,000 packages loaded with extras like business banking referrals, logo design, and website builders. You can get most of these services cheaper elsewhere or handle them yourself. Stick to basic formation + registered agent service.

2. Forgetting About Annual Requirements

Every state requires annual reports or franchise tax payments. Miss these deadlines and you’ll pay penalties or risk losing your business entity. Set calendar reminders when you file.

3. Using the Wrong State for Tax Reasons

Filing in Nevada or Wyoming to “avoid taxes” backfires if you live in California or New York. You’ll still owe taxes in your home state plus deal with foreign entity registration. File locally unless you have specific strategic reasons.

4. Mixing Personal and Business Finances

Opening a business bank account isn’t just nice-to-have — it’s essential for maintaining legal protection. Mixing funds gives courts reason to “pierce the corporate veil” and go after your personal assets.

5. Choosing Corporation When You Meant LLC

Corporations require more paperwork, board meetings, and complex tax elections. Many people choose “Corporation” because it sounds more official, then regret the extra complexity. LLC works better for most small businesses.

6. Not Getting Professional Tax Advice

Business formation changes your tax situation. A CPA consultation before you file can save thousands in taxes and help you choose the right entity structure for your specific situation.

For International Founders

Good news: You don’t need to be a U.S. citizen or resident to start a U.S. business. Foreign nationals can form LLCs or corporations in any state.

Best States for International Founders

Wyoming: Maximum privacy (no public owner information), low costs ($100 filing fee), no state income tax, and business-friendly laws.

Delaware: Globally recognized business laws, investor-friendly legal precedents, and specialized business courts. Popular with startups planning to raise money.

What You’ll Need

You must have a registered agent with a U.S. physical address. Services like BusinessFormations.com provide this for international clients.

Getting your EIN takes longer as a non-U.S. resident. You’ll need to file Form SS-4 by fax instead of applying online. Processing takes 4-8 weeks versus immediate online approval for U.S. residents.

Banking Challenges

Opening a U.S. business bank account as a foreign owner is the biggest hurdle. Traditional banks often require you to visit in person.

Online options like Mercury, Relay, and Wise Business work better for international founders. They’re designed for remote account opening and serve non-resident business owners.

Tax Obligations

Foreign-owned single-member LLCs must file Form 5472 annually with the IRS, even if the business has no income. Penalties for not filing start at $25,000, so don’t skip this.

Multi-member LLCs and corporations have different reporting requirements. Work with a CPA who specializes in international tax compliance — this isn’t the area to figure out yourself.

Frequently Asked Questions

How long does it take to start a business legally?

Same day to one week, depending on your state’s processing time. Expedited filing costs extra but gets approval within 24-48 hours in most states.

Can I start a business with a partner?

Yes, but create a detailed operating agreement that covers ownership percentages, decision-making authority, and exit procedures. Most partnership disputes come from unclear expectations upfront.

Do I need business insurance right away?

Depends on your business type. Service businesses should get professional liability insurance before taking on clients. Retail or manufacturing businesses need general liability coverage. Talk to an insurance agent familiar with your industry.

What if someone already has my business name?

You can’t use a name that’s already registered in your filing state. Check the availability before you get attached to a name. Business name registration is separate from trademark protection — consider both if branding is important.

Should I get a trademark?

Not immediately for most businesses. Focus on getting legally operational first. You can always file trademarks later once your business is established and you know which names and logos you want to protect.

Can I change my business structure later?

Yes, but it involves paperwork and potential tax consequences. LLCs can elect corporate tax treatment without changing entity type. Converting between LLCs and corporations requires dissolving one entity and creating another.

Do I need a business license?

Depends on your business type and location. Professional services (contractors, restaurants, healthcare) typically need licenses. Online businesses often don’t. Check with your city and state licensing departments.

What happens if I do business without forming an entity?

You’re operating as a “sole proprietorship” by default. This means no liability protection — customers or creditors can go after your personal assets. You also can’t open business bank accounts or sign contracts in a business name.

Ready to Get Started?

Starting a business legally isn’t complicated once you understand the steps. Choose your structure, pick your state, file your paperwork, and get your tax ID. Most people can handle the entire process in a day or two.
