How to Register a Business in the USA: The Complete Guide for Home-Based, Online, and Service Businesses

Every guide on registering a business in the US reads like a government form: pick a structure, get an EIN, file with the state, done. That’s true as far as it goes — but it skips the parts that actually trip people up. It doesn’t tell a home baker whether her zoning laws allow a commercial kitchen. Not tell an Etsy seller in Texas that shipping to California might mean she owes California sales tax. It doesn’t tell a freelance designer in Lahore or Manila how to actually register a company from outside the US.

Quick answer: Registering a business in the US means choosing where and under what structure to form it, picking and protecting a name, getting a free EIN from the IRS, filing with your state, securing the licenses your specific business activity requires, and then keeping up with the paperwork that shows up after registration. Most people finish the core filing in 1–3 weeks.

This guide walks through the whole process — but built around the three kinds of businesses most people are actually starting: home-based businesses, online businesses, and service businesses. Wherever the requirements diverge for these three, we’ll say so explicitly.

One thing this guide won’t do is re-litigate two decisions you may have already made.

If you’re still deciding between a sole proprietorship and an LLC, our LLC vs. sole proprietorship comparison and do I need an LLC to start a business breakdown cover that decision in full, with a 4-question test and real cost math.

And once you’re registered, how to open a business bank account walks through banking step by step for home-based, online, and service businesses specifically.

This article picks up everything in between: the actual mechanics of getting your business legally on the books.

What Does It Mean to Register a Business in the USA?

“Registering a business” does not always mean filing one universal federal application.

Depending on your situation, you may need to:

• Form a legal business entity with a state
• Register a DBA or trade name
• Obtain an EIN from the IRS
• Register for state taxes
• Register for sales tax
• Obtain city or county business licenses
• Obtain professional or industry-specific licenses
• Register as an employer
• Qualify to do business in another state
• Register for federal contracting if you want government contracts

The U.S. Small Business Administration similarly separates business launch into different areas, including location, structure, name, state registration, tax IDs, licenses, banking, and insurance.

The important idea is this: your business can have several registrations, not just one.

The U.S. Business Registration Roadmap

Think about registration as a business compliance stack.

You won’t necessarily need every item.

The goal is to identify only the registrations that apply to your business.

Step 1: Decide Where to Register — This Comes Before Everything Else

This is the step most registration guides bury or skip entirely, and it’s the one that determines your costs for years.

The default rule: if you have a physical presence, employees, or most of your customers in one state, register there. Registering in Delaware while you live and work in Ohio just means paying Ohio and Delaware fees — this is called “foreign qualification,” and it’s extra paperwork, not a shortcut.

When it’s worth registering somewhere else:

Wyoming and Delaware get recommended constantly online, and for the right business they’re genuinely good — but for a home-based Etsy shop or a local cleaning service, they add a second state’s worth of paperwork with no real upside. Match the state to what your business actually does.

Before choosing a state, ask:

1. Where do I live?
2. Where is the business physically operated?
3. Where are employees located?
4. Where do I regularly provide services?
5. Where does the business have a meaningful physical presence?
6. Do I have a reason to form somewhere other than my home state?

Don’t choose a state purely because someone online says it is “business friendly.”

Step 2: Confirm Your Structure (Quickly)

You need a structure decided before you can file anything, but this article won’t repeat the decision framework in full — that’s already covered in depth elsewhere on the site. Here’s the two-sentence version:

1. Sole proprietorship costs nothing to start and works fine for low-risk, low-revenue testing.
2. LLC costs $50–$500 depending on your state and creates a legal wall between your personal assets and business liabilities — worth it the moment you’re taking on real clients, handling other people’s property, or bringing on a partner.

If you want the actual decision test — a 4-question scorecard instead of a vague “it depends” — read LLC vs. sole proprietorship: which is right for you.

If you’re specifically weighing whether your home-based, online, or service business needs an LLC at all before you spend a dollar on formation fees, do I need an LLC to start a business breaks it down by exactly those three categories with real-world examples. Come back here once you’ve decided — everything below assumes you know your structure.

One note this article will add: if you’re a licensed professional — lawyer, accountant, architect, therapist — some states require a PLLC (Professional LLC) instead of a standard LLC.

This is an easy detail to miss, and filing the wrong one can invalidate your liability protection entirely.

Check your state’s licensing board before you file.

Step 3: Pick and Protect Your Business Name

There are four separate name registrations, and people conflate them constantly:

• Entity name — protects your name at the state level, part of forming your LLC or corporation
• Trademark — protects your name and brand nationally, filed with the USPTO, separate from state registration
• DBA (“doing business as”) — lets you operate under a name different from your legal entity name; doesn’t provide legal protection on its own
• Domain name — your website address; doesn’t need to match your legal name

Before you commit, search the USPTO trademark database and your state’s business name registry. For online businesses especially, check domain availability and social handles before you file — finding out your entity name is legally registered but the matching .com and Instagram handle are already taken is a common and avoidable frustration.

Step 4: Get Your EIN

Your EIN (Employer Identification Number) is your business’s federal tax ID — free to get, and required to open a bank account, hire employees, and file most business taxes.

If you’re a US resident with a Social Security Number: apply online through the IRS EIN Assistant. You’ll have your EIN in minutes.

If you’re a non-US resident without an SSN: you do not need an SSN or ITIN to get an EIN. You can apply by phone (+1-267-941-1099), fax, or mail using IRS Form SS-4, listing “Foreign” in the SSN/ITIN field. This can take anywhere from same-day (phone) to several weeks (mail). An ITIN is a separate number, needed only if you personally — not your business — have to file a US tax return.

Most non-resident business owners need an EIN for the business but not necessarily an ITIN, unless they’re drawing a salary or their structure requires it.

Getting the EIN does not give you the right to work in the US or obtain a visa — it only lets your business exist and transact legally.

Step 5: File With the State

Once you’ve chosen a structure and location, filing is mechanical: submit your Articles of Organization (LLC) or Articles of Incorporation (corporation) to the Secretary of State, pay the filing fee (typically $50–$300 depending on the state), and, if required, appoint a registered agent — a person or company with a physical address in that state who receives legal documents on your behalf.

Non-residents and anyone forming an LLC in a state where they don’t live are required to have a registered agent. Formation services (Northwest Registered Agent, ZenBusiness, Firstbase, doola) typically bundle this in for $100–$150/year.

If you’ll be doing meaningful business in more than one state — physical presence, employees, or a large share of revenue — you’ll also need foreign qualification in each of those states. Purely online businesses with no physical footprint outside their formation state generally don’t trigger this, though sales tax rules (covered below) are a separate matter entirely.

Step 6: Licenses and Permits — This is Where the Three Business Types Genuinely Diverge

Generic guides say “check your state and local requirements” and move on. Here’s what that actually means for each business type.

If you’re running a home-based business

• Home occupation permit: many cities require this separately from your business license, specifically because you’re operating out of a residential zone. Some HOAs and lease agreements also restrict business activity — check before you build a customer base around a location you may have to abandon.
• Zoning check: even home-based businesses aren’t automatically exempt from zoning ordinances, especially if you’re seeing clients at your home, storing inventory, or running equipment (a home bakery’s commercial oven, for example).
• Health permits: food-based home businesses (baking, catering, meal prep) typically fall under “cottage food laws,” which vary hugely by state.
• Insurance gap: most homeowners’ policies exclude business activity entirely — worth a call to your provider before you assume you’re covered.

For a broader look at what qualifies and what to plan for, see our guide to starting a service business from home.

If you’re running an online business

• Seller’s permit / sales tax permit: required in most states if you sell taxable goods, obtained from your state’s Department of Revenue.
• Sales tax nexus — the most misunderstood requirement for online sellers: since the 2018 South Dakota v. Wayfair Supreme Court decision, you can owe sales tax in a state even without a physical presence there, once your sales into that state cross a certain threshold (commonly $100,000 in sales or 200 transactions per year, though thresholds vary by state). If you sell through Amazon, Etsy, or a similar marketplace, “marketplace facilitator” laws in most states now shift the tax collection burden onto the platform — but confirm this for each marketplace you use, since rules and thresholds differ.
• If you’re a small seller, you likely won’t hit nexus thresholds for a while — but it’s worth checking a nexus tracking tool (TaxJar, Avalara) as your ecommerce business scales, rather than finding out retroactively.

If you’re running a service business

• Professional or occupational licenses: contractors, cosmetologists, real estate agents, financial advisors, and dozens of other service categories require state-issued licenses tied to the individual, not just the business.
• Local business operating license: many cities require a general license to operate within city limits, particularly if you meet clients in person.
• Industry certifications: not always legally required, but often expected by clients (bonding for contractors, professional liability coverage for consultants).

For a category-by-category breakdown of which service businesses carry the most licensing complexity, our service business ideas guide sorts dozens of options by risk and startup cost — useful context before you assume your idea needs (or doesn’t need) a specialized license.

Step 7: Open Your Business Bank Account

Once your EIN and formation documents are in hand, you’ll need a dedicated business account — not optional in practice, since commingling personal and business funds is one of the fastest ways to lose the liability protection an LLC is supposed to give you.

This article won’t repeat the full process here, because how to open a business bank account already covers it in detail — the documents every bank asks for, how to handle the “business address” question when you work from home, which banks fit online sellers with international payment volume, and how non-resident founders without an SSN can get a US business account through fintech platforms like Mercury or Wise Business.

If banking is your next step, that’s the guide to open next.

Step 8: Understand Your Taxes — and What Comes After Registration

Federal, state, and local taxes vary by structure and location — that part is well covered elsewhere, so we won’t repeat the full breakdown here. What’s consistently left out of registration guides is what happens after you register, which is where people get caught off guard:

Set calendar reminders for these the day you finish registering. The single most common way small businesses lose their good standing isn’t fraud or mismanagement — it’s forgetting an annual report that costs $20–$50 to file.

Registering from Outside the US: A Condensed Path

If you’re a non-resident founder, here’s the sequence stripped down to what actually differs from the general process:

1. Choose Wyoming or Delaware unless you have a specific reason to pick another state
2. Form an LLC — simpler than a corporation for most non-resident founders unless you’re raising venture capital (our LLC breakdown explains why this structure fits most solo and small-team businesses)
3. Hire a registered agent — mandatory, since you don’t have a US address
4. Apply for your EIN by phone, fax, or mail (not online)
5. Open a business bank account with a fintech provider built for non-resident founders — see our banking guide for specific platforms
6. Confirm whether you personally need an ITIN based on how you plan to take money out of the business — worth a short consultation with a cross-border accountant

This setup lets you invoice US clients, accept US payments, and operate legally — but it does not grant you the right to work or live in the US. That’s a separate, unrelated legal question (visas), and no amount of business registration changes it.

Do You Need to Register a Business in More Than One State?

Sometimes.

Imagine you form a business in State A but later establish a significant business presence in State B.

You may need to register the existing business in State B through a process commonly called foreign qualification.

The term can sound confusing.

It does not necessarily mean your owners are foreign citizens.

It generally refers to a business entity formed in one state registering to conduct business in another state.

The SBA notes that businesses operating across multiple states may need to form in one state and obtain foreign qualification in others where they conduct business activities.

Possible triggers can include:

• Physical offices
• Employees
• Regular in-person activity
• Significant business operations
• Other state-specific connections

Don’t automatically register everywhere just because you have customers there.

State rules differ.

What About Beneficial Ownership Information (BOI) in 2026?

This is an area where older business-registration articles can now give you outdated information.

As of September 2026, FinCEN has changed the federal beneficial ownership reporting rules.

On August 11, 2026, FinCEN announced a final rule permanently removing BOI reporting requirements for U.S. companies and U.S. persons. Certain foreign entities registered to do business in the United States can still fall within the reporting requirements.

That means you should not blindly follow older guides telling every newly formed U.S. LLC or corporation to submit a BOI report.

The practical takeaway

If you are creating a company under U.S. law, don’t assume that a BOI filing is required simply because an older article says so.

If you’re dealing with a foreign entity registered to do business in the United States, the analysis can be different.

Because BOI rules have changed, always verify the current requirements directly with FinCEN before filing.

Common Mistakes, Sorted by Business Type

Home-based businesses: skipping the home occupation permit because “it’s just me working from my kitchen table” — until a neighbor complains or an inspector visits mid-operation.

Online businesses: assuming no physical location means no sales tax obligations anywhere — nexus rules mean this often isn’t true once you scale past a threshold in any state.

Service businesses: operating without any legal separation for too long because “I don’t own much yet” — the exposure isn’t about what you own today, it’s about what a client dispute could claim from you next year. If you’re unsure where that line sits for your specific work, the risk breakdown in do I need an LLC to start a business sorts common service categories by risk level.

All three: choosing a registered agent or formation service purely on price, then discovering the cheap option doesn’t forward legal documents promptly — which can mean missing a lawsuit notice entirely.

Frequently Asked Questions

Do I need an LLC to register a business, or can I just use my own name?

No — you can legally operate as a sole proprietor using your own name and Social Security number, and in most states this requires no state filing at all. Whether that’s the right call depends on your risk exposure; see LLC vs. sole proprietorship for the full decision test.

Can I register a US business without living in the US?

Yes. Non-residents can form an LLC or corporation in any US state, provided you use a registered agent with a physical address in that state. You don’t need a visa or US address to own a US business — you do need one to legally work inside the US.

Do I need a business license to run a home-based online business?

Often yes, even if you never see a customer in person. Most cities require a home occupation permit or general business license for any commercial activity based at a residential address, regardless of whether transactions happen online.

What’s the cheapest state to register an LLC in?

Cost isn’t just the filing fee — it’s filing fee plus registered agent plus any annual franchise tax. For most people running a business physically located in one state, that state is the cheapest option overall, since forming elsewhere adds a second layer of fees without removing the first.

How long does it take to get an EIN as a non-US resident?

Phone applications can be same-day; fax typically takes about a week; mail applications can take four weeks or more. There’s no online option for applicants without a US SSN or ITIN.

What should I do right after I register — bank account or taxes first?

Bank account first, in practice, since you’ll need it to receive payments and pay for licenses or software. Our step-by-step business bank account guide covers exactly what to have ready before you apply.

Final Takeaway

Registering a business in the USA isn’t simply about forming an LLC.

For some entrepreneurs, the process may involve little more than choosing a structure, handling state requirements, getting an EIN, and checking local licensing.

For others—especially ecommerce companies, regulated service businesses, employers, multi-state businesses, and businesses owned from outside the United States—the compliance picture can be much broader.

The smartest approach is to build your registration checklist around your actual business, rather than copying someone else’s.

And remember:

Business formation, tax registration, licensing, banking, and trademark protection are different pieces of the puzzle.
