How to Register a Business: Step-by-Step Guide for 2026

Last updated: May 2026 | Author: SmallBizSimple Editorial Team

This guide is for informational purposes only. Business registration requirements vary by state. Consult an attorney or CPA before making legal entity decisions.

Introduction

To register a business in 2026, you need to: (1) choose a structure — LLC for most small businesses, (2) file Articles of Organization with your state ($40–$500), (3) get an EIN from IRS.gov for free, (4) register for state tax accounts, and (5) obtain local business licenses. Total setup time: 1–3 weeks. Total cost for a DIY LLC: $65–$800 depending on your state.

Starting a business is exhilarating. But before you open your doors — physical or digital — there's a legal reality you can't skip: business registration.

Registering your business is the process of formally creating your company as a legal entity recognized by the government. Done right, it protects your personal assets, unlocks business banking and credit, makes you IRS-compliant, and sets you up to legally hire employees, sign contracts, and collect payments.

Done wrong — or skipped entirely — it exposes you to personal liability, banking rejections, and penalties from the IRS and your state.

What Is Business Registration?

Business registration is the legal process of formally establishing your company with government authorities. It creates an official record that your business exists — either as an extension of yourself (sole proprietorship) or as a separate legal entity (LLC, corporation) with its own rights and obligations.

Registration is not a single form. Depending on your business type and location, it may involve:

State-level entity filing — creating an LLC, corporation, or partnership with your state's Secretary of State office
Federal tax registration — obtaining an Employer Identification Number (EIN) from the IRS
Local permits and licenses — city or county business licenses, industry permits, and zoning approvals
DBA (Doing Business As) registration — if you're operating under a name different from your legal entity name

The specific combination you need depends on your business structure, your state, your industry, and whether you'll have employees.

How Business Registration Works

The core mechanics of business registration flow through three levels of government:

Federal Level (IRS)

The IRS does not "register" businesses the way states do — but it does assign your Employer Identification Number (EIN), which is the federal tax ID your business uses for tax filings, banking, payroll, and more. Most businesses need an EIN even if they have no employees.

You apply for an EIN online at IRS.gov for free and receive it instantly. It's one of the fastest steps in the entire process.

State Level (Secretary of State)

This is where you formally create your business entity. Each state has its own filing office — usually the Secretary of State or Division of Corporations — that accepts Articles of Organization (for LLCs) or Articles of Incorporation (for corporations).

Filing fees range from $40 (Kentucky) to $500+ (Massachusetts), and processing times range from same-day (online) to several weeks (paper filing).

After your entity is created, many states require you to register separately with the Department of Revenue for state tax purposes, and with the Department of Labor if you will have employees.

Local Level (City/County)

Most cities and many counties require a local business license. Some industries — restaurants, childcare, contractors, healthcare — require additional permits. And if you're operating from a physical location, zoning approval may be required.

Local requirements are the most variable and the most frequently overlooked part of business registration.

Business Structure Types: The Decision That Shapes Everything

Choosing your business structure is the most consequential decision in the registration process. Your structure determines your liability exposure, tax treatment, administrative burden, and fundraising ability.

Sole Proprietorship

The default for individual business owners who do nothing formal. There's no state filing — you're simply operating under your own name (or a DBA). But you have zero liability protection: business debts and lawsuits reach your personal assets directly.

Best for: Freelancers testing an idea with minimal risk before formalizing.

Not for: Anyone with meaningful income, clients who could sue, or plans to grow.

General Partnership

Two or more people operating a business together, with shared liability. Like a sole proprietorship, it's formed by operation — not state filing — but a written partnership agreement is strongly advised.

Best for: Early-stage co-founders who want to formalize decision-making without the complexity of an LLC.

Not for: Situations where partners need personal liability protection.

Limited Liability Company (LLC)

The most popular structure for small businesses in 2026. An LLC is a separate legal entity that protects your personal assets from business debts and lawsuits. It's taxed as a pass-through entity by default (profits and losses flow to your personal return), but it can elect S-corp or C-corp taxation.

LLCs offer flexibility without the formality requirements of corporations. No board meetings required, no rigid share structure. Just an Operating Agreement, annual reports in most states, and a filing fee.

Best for: Most small businesses — solo operators, service businesses, e-commerce, real estate investors.

Not for: Businesses seeking venture capital (investors typically want a Delaware C-corp).

S Corporation

A corporation that has elected special tax status with the IRS, allowing it to avoid double taxation. Profits and losses pass through to shareholders' personal returns, but a portion of income can be paid as distributions (not subject to self-employment tax), potentially generating significant tax savings for profitable businesses.

You first form a corporation at the state level, then file IRS Form 2553 to elect S-corp status.

Best for: Profitable businesses (typically $50,000+ net profit) where the payroll/distribution split creates meaningful self-employment tax savings.

Not for: Early-stage businesses not yet consistently profitable, or businesses with non-US resident owners.

C Corporation

A corporation taxed as a separate entity. Subject to double taxation (corporate income tax + shareholder dividend tax), but the preferred structure for venture-backed startups due to multiple share classes, unlimited shareholders, and investor familiarity.

Delaware is the most common state of incorporation for C-corps, even for companies operating elsewhere.

Best for: Businesses planning to raise venture capital, have many investors, or go public.

Not for: Small owner-operated businesses where the tax disadvantage outweighs any benefit.

Benefits of Formally Registering Your Business

Registering your business formally — specifically as an LLC or corporation — delivers concrete advantages beyond legal compliance:

Personal liability protection. Your home, savings, and personal assets are shielded from business lawsuits and creditors. This is the single most important reason to form an LLC.

Business banking access. Most banks require an EIN and a formal entity to open a business checking account. Operating through a personal account creates accounting nightmares and can pierce the liability veil. See our guide to the best business bank accounts for small business to start this correctly.

Business credit building. An EIN is the foundation of your business credit profile. Without it, you cannot build credit separate from your personal score.

Contractual credibility. Signing contracts as "ABC, LLC" rather than your personal name signals professionalism and protects you personally.

Tax optimization. Proper entity structure opens deduction opportunities and, in the case of S-corps, self-employment tax savings. Your business tax deductions checklist starts with a registered entity.

Employee hiring. You cannot legally put someone on payroll without an EIN and proper state employer registration. See our guide to best payroll software for small business for what comes next.

Drawbacks to Be Aware Of

Annual maintenance costs. Most states charge annual report fees ranging from $25 to $500+. California's minimum franchise tax is $800/year — even if your LLC earns nothing.

Administrative overhead. LLCs and corporations require separate records, bank accounts, and financials. Commingling personal and business funds can "pierce the corporate veil" and destroy your liability protection.

More complex taxes. A registered entity changes your tax filing requirements. Budget for accounting software or a CPA. Our small business accounting software guide covers the tools that handle this efficiently.

Step-by-Step: How to Register a Business in 2026

Here is the complete registration sequence for an LLC — the most common small business structure — in 2026.

Step 1: Choose Your Business Name

Before filing anything, verify your name is available:

Search your state's Secretary of State business name database
Search the USPTO trademark database (USPTO.gov) to avoid federal trademark conflicts
Check domain availability — your business name should have a matching .com
Search social media handles for consistency

Your LLC name must include a designator — "LLC," "L.L.C.," or "Limited Liability Company" — and must be distinct from existing entities in your state.

Tip: Reserve the name immediately if your state allows it (usually $10–$50). Do not apply for your EIN or open a bank account until the name is confirmed.

Step 2: Choose a Registered Agent

A registered agent is a person or company designated to receive official legal and government correspondence on behalf of your business. Every LLC and corporation is required to have one.

Your options:

Yourself — you must have a physical address in the state of formation, not a PO box
A business partner or employee with a physical in-state address
A registered agent service — $50–$300/year

If you're forming in a state where you don't physically operate — like Delaware — you'll need a commercial registered agent. Our guide to best LLC formation services covers services that bundle registered agent into their pricing.

Step 3: File Your Articles of Organization

This is the official formation document. For an LLC, it's called Articles of Organization. For a corporation, Articles of Incorporation.

What you'll typically need to include:

Business name
Registered agent name and address
Principal business address
Member names (in some states)
Business purpose (often just "any lawful purpose")
Management structure (member-managed vs. manager-managed)

Where to file: Your state's Secretary of State website. Most states have online filing. Filing fees: $40–$500 depending on your state.

Processing time: 1–10 business days for online filing in most states. Expedited same-day processing is available for an additional fee in most states.

Step 4: Create an Operating Agreement

An Operating Agreement is an internal document — you don't file it with the state — that defines how your LLC operates: ownership percentages, profit/loss distribution, decision-making authority, and what happens when a member exits or the business dissolves.

Some states (California, Delaware, Maine, Missouri, New York) legally require an Operating Agreement. In all states, having one:

Prevents expensive disputes between owners
Strengthens liability protection by demonstrating you treat the business as separate from yourself
Satisfies lender and investor requirements

Cost: Free with a template. $200–$1,000 if drafted by an attorney for complex multi-member LLCs.

Step 5: Obtain Your EIN

An EIN is a nine-digit federal tax ID number assigned by the IRS. Think of it as a Social Security Number for your business.

You need an EIN if you:

Have employees (or plan to)
Operate as a multi-member LLC
File excise taxes
Open a business bank account (most banks require it)
Work with vendors who may issue 1099s to you

Apply at: IRS.gov → EIN Assistant. Free. Takes 10–15 minutes. EIN issued instantly online.

Important: Apply in the name of your LLC (not your personal name) if you have already formed the entity.

Step 6: Register for State Tax Accounts

Depending on your business type, register with your state's Department of Revenue for:

Sales tax permit — Required if you sell taxable goods or services. Free to apply in most states.
State income tax withholding — Required if you have employees.
Unemployment insurance — Requires a separate Department of Labor registration in most states.
Franchise/privilege tax — Some states (California, Texas, Delaware) charge this regardless of income.

Do not skip this step. Operating with employees or collecting sales tax without proper state registration creates significant back-tax liability and potential penalties.

Step 7: Obtain Local Licenses and Permits

Check both your city and county requirements:

General business license — Many cities require this for all businesses operating within city limits ($25–$500/year)
Zoning permit — If operating from a physical location, including some home offices
Industry-specific permits — Health permits, contractor licenses, professional licenses, seller's permits
Signage permits — If posting outdoor signage

The most reliable resource: your city's official website or the SBA's Business License and Permits tool at SBA.gov.

Step 8: Open a Business Bank Account

This is not a formal registration requirement, but it's a non-negotiable business practice you should complete immediately after your EIN arrives.

Why it matters:

Separating business and personal finances is the single most important factor in maintaining liability protection
Required for bookkeeping accuracy and tax deductions
Required for business credit card applications
Required by lenders for business loans

What you'll need: EIN, Articles of Organization, government-issued ID, and an opening deposit (as low as $0 at Mercury or Relay). See the best business bank accounts for small business for current options.

How to Choose the Right Business Structure

These decision points narrow your choice quickly:

Are you the only owner? If yes, sole proprietorship or single-member LLC.
Do you need liability protection? If yes, LLC or corporation — not sole proprietorship.
Will you seek venture capital? If yes, Delaware C-corp.
Is your net profit above $50,000/year? If yes, S-corp election may save self-employment taxes — model this with a CPA.
Are you in a licensed profession? Attorneys, doctors, and accountants in some states must form a PLLC (professional LLC) or PC (professional corporation).

The 2026 default for most small businesses: Form a single-member LLC, use disregarded entity status for taxes (the IRS default), and revisit S-corp election when net profit consistently exceeds $50,000/year.

Common Mistakes to Avoid

1. Registering in Delaware or Wyoming "for the benefits" when you don't operate there.
You'll still need to register as a foreign entity in your home state — paying registration fees in both. For most small businesses, forming in your home state is simpler and cheaper.

2. Skipping the Operating Agreement because it's not state-required.
One business dispute without an Operating Agreement can cost more in legal fees than a decade of annual state filing fees.

3. Mixing personal and business finances.
Using your personal checking account for business transactions — even temporarily — pierces the corporate veil and undermines liability protection. Open the business account immediately after getting your EIN.

4. Missing state tax registrations.
Entity formation (Articles of Organization) and state tax registration are two separate filings. Many new owners think forming the LLC is enough. It is not.

5. Choosing a name without clearing federal trademark.
The Secretary of State database only searches your state. A federal trademark owner can force a rebrand — with legal fees — even if your state approved the name.

6. DIY Operating Agreements for complex multi-member LLCs.
Templates work for simple single-member LLCs. Multi-member LLCs with unequal ownership, different contribution types, or complex exit scenarios need attorney review.

7. Missing industry-specific licenses.
Restaurant owners who ignore health permits, contractors who skip contractor licensing, and childcare operators who miss state certification requirements face forced closure and fines. Research your industry requirements before day one.

Frequently Asked Questions

How long does it take to register a business?
Online LLC formation typically takes 1–5 business days with your state. The EIN is issued instantly online. Add 1–2 weeks for business bank account opening and local license processing. Plan for 2–4 weeks from start to fully operational.

Do I need a lawyer to register a business?
No. Most single-member LLCs can be registered without a lawyer using your state's online filing portal and a template Operating Agreement. An attorney adds value for multi-member LLCs with complex ownership structures or businesses in regulated industries.

Can I register my business online?
Yes. All 50 states offer online entity filing through their Secretary of State website. The EIN is applied for online at IRS.gov. Most local licenses have online options in major cities.

Do I need to register in every state I do business in?
If your business has a physical presence (office, employees, warehouse) in multiple states, you'll need to register as a foreign entity in those states — fees typically $50–$300 per state. Remote sales alone generally do not trigger this requirement, but sales tax nexus rules apply separately.

What's the difference between an LLC and a DBA?
An LLC is a separate legal entity that protects your personal assets. A DBA (Doing Business As) is just a trade name — it does not create any entity or provide liability protection. A sole proprietor can file a DBA to operate under a business name but remains personally liable for all obligations.

What is a registered agent and do I need one?
Yes. Every LLC and corporation is required by law to designate a registered agent — a person or service with a physical in-state address that receives official government and legal correspondence. You can serve as your own registered agent if you have a physical address (not a PO box) in the state of formation.

Can a single person form an LLC?
Yes. Single-member LLCs are the most common business structure for solo entrepreneurs in 2026. You file as a disregarded entity for federal taxes (profits and losses on your personal return via Schedule C) and maintain full liability protection.

What is an S-corp and should I form one?
An S-corp is a tax election, not a separate entity type. You first form an LLC or corporation, then file IRS Form 2553 to elect S-corp status. The main advantage: splitting business income between salary (subject to payroll taxes) and distributions (not subject to self-employment tax). This typically becomes beneficial at $50,000+ net profit/year. Consult a CPA before electing.

Do I need a business license if I'm a freelancer?
It depends on your city. Many cities require a general business license for anyone earning commercial income within city limits, regardless of business structure. Your industry may also require professional licenses.

What happens if I don't register my business?
Operating without registration means no liability protection, no business banking, difficulty signing enforceable contracts, potential state penalties for operating without a license, and tax complications. Most states allow retroactive LLC formation, but it is simpler and safer to register before you begin operating.

How do I register a business in multiple states?
Form your LLC in your primary home state first. For each additional state where you have physical presence, file a Foreign LLC Registration (typically $50–$300 per state). Remote customers in other states generally do not trigger foreign registration requirements, though sales tax nexus rules may apply.

How do I register a business with no money?
The lowest-cost path: form an LLC in Kentucky ($40), apply for an EIN online (free), serve as your own registered agent, use a free template Operating Agreement, and open a no-minimum business bank account at Mercury or Relay. Total cost: $40–$60. Some industries require paid permits regardless of entity type.

What's the difference between a business license and an LLC?
They serve different purposes. An LLC is a legal entity that provides liability protection and tax separation. A business license is a government permit to operate commercially in a specific location. Most small businesses need both.

Can I register my business name as a trademark?
State registration and federal trademark protection are separate. The Secretary of State approves your entity name within your state only. Federal trademark registration (via USPTO) protects your brand name nationwide within specific goods and services categories. If brand identity is central to your business model, consult an IP attorney about trademark registration.
