How to Start a Business: A Step-by-Step Guide (2026)

This guide was last reviewed and updated in October 2026. Filing fees, tax rules, and registration procedures change regularly — always confirm current details with your Secretary of State’s office and the IRS before filing.

The Census Bureau counted roughly 524,000 new business applications filed in May 2026 alone, and the SBA reports 36.2 million small businesses now operating in the U.S. — 99.9% of all American firms (SBA Office of Advocacy, February 2026). Yet the gap between “I have an idea” and “I have a business” stops most people cold. The process looks bureaucratic and expensive, and one wrong choice — the wrong structure, a paid EIN scam — can cost you hundreds you didn’t need to spend.

This guide breaks the whole thing into nine practical steps, in the order you should actually do them — for first-time founders starting lean, with no lawyer on retainer and no big bank loan.

What “Starting a Business” Actually Means: Legal vs. Practical

Legally, “starting a business” means your business is recognized by the state and the tax system: a registered entity (or at minimum a registered name), a federal tax ID where required, and the licenses and permits your city or industry demands. This is the paperwork side, and it’s the part this guide walks through in detail.

Practically, a business starts when someone pays you. You can do much of the practical side — researching the market, talking to customers, even taking a first payment as a sole proprietor — before the paperwork is done. The SBA’s own launch checklist follows this logic: research and plan first, then handle structure, registration, tax IDs, licenses, and a business bank account.

The smart approach: validate the idea while the paperwork is in motion, so you aren’t spending months “preparing” and zero hours selling.

Step 1: Validate the Idea Before You Spend a Dollar

Validation means proving, with real evidence, that strangers will pay for what you plan to sell. Do it in two to three weeks, before spending a dollar:

• Write the one-sentence business hypothesis. “I help [specific customer] achieve [specific result] through [product or service].” If you can’t name the customer and the result, you’re not ready.
• Interview 10–15 potential customers — not friends. Ask about the problem, what they’ve tried, and what they’d pay to fix it. Five “I’d pay for that” responses is your green light.
• Size the market with free data. The SBA, Census Bureau, and trade associations publish demand figures for most niches. A market too small to support your income goal is a hobby, not a business.
• Check the competition. Established competitors mean real demand — but you need a differentiator: price, speed, niche, or service quality.
• Pre-sell something. A landing page with a “reserve” button, a paid deposit, a signed letter of intent. Payment is the only validation that counts.

If validation fails — no one will pay, or the numbers don’t work — you’ve saved thousands. Pivot the idea or the customer and run the test again. This is the cheapest step in the whole process, which is why it comes first.

Step 2: Write a One-Page Business Plan

Unless you’re applying for a bank or SBA loan, skip the 40-page plan — a one-pager is enough. Cover these eight sections:

1. Problem: The painful problem your customers have right now.
2. Solution: What you sell and how it fixes the problem.
3. Target customer: A specific profile — age, income, location, habits.
4. Value proposition: Why you, in one sentence.
5. Revenue model: One-time sales, subscriptions, project fees, or hourly rates.
6. Startup costs: Your realistic estimate.
7. Marketing channels: The two or three ways you’ll reach customers first.
8. Milestones: First-sale and breakeven targets, with dates.

Lenders that ask for a full plan expect the classic sections: executive summary, company description, market analysis, management, product line, marketing strategy, funding request, and projections. Expand your one-pager only if asked.

Step 3: Figure Out Your Startup Budget

Startup costs vary enormously by business type. A home-based service business can launch for a few hundred dollars; a restaurant or retail store can require $8,000 to $200,000+ in first-year costs (Homebase, September 2026). The common categories:

• Formation and legal: State LLC filing fees run roughly $35 to $500 (median around $100), plus optional registered agent services at $100–$300 per year (OpenChamber, October 2026). Don’t forget annual fees — California’s $800-per-year minimum franchise tax applies even at zero revenue.
• Licenses and permits: General business licenses typically $50–$200; industry-specific permits $50–$500+ (BoostSuite; Homebase, September 2026).
• Insurance: First-year general liability often $350–$500; a business owner’s policy around $515–$685 (Homebase, September 2026).
• Equipment and inventory: $0 for pure services; $2,000–$50,000+ for product businesses.
• Website and branding: $500–$1,500 for a functional small-business site is typical; DIY platforms run $12–$40/month (Homebase, September 2026).

Fund it with savings, a side-hustle runway, or a 0% intro-APR business card you pay off before the promo ends. Only 42% of small-business credit applicants got all the financing they sought in the Fed’s latest survey (SoFi/SBCS, 2026) — plan as if outside funding won’t come.

Step 4: Choose a Legal Structure

Your structure decides three things: personal liability, taxation, and paperwork. The three that cover nearly every new small business:

Feature	Sole Proprietorship	LLC	S Corporation
Personal liability	None — you and the business are legally the same; creditors can reach personal assets	Limited — personal assets generally protected if you maintain separation	Limited — same separation principle as LLC
How profits are taxed	Pass-through: reported on your personal return (Schedule C), subject to self-employment tax	Pass-through by default (Schedule C for single-member); can elect S-corp or C-corp taxation	Pass-through, but owners must take a “reasonable salary” subject to payroll taxes; remaining profits avoid self-employment tax
Typical formation cost	$0–$100 (often just a DBA filing with your county)	$35–$500 state filing fee, plus annual fees/taxes that vary widely by state	$100–$300+ state incorporation fees, plus ongoing corporate formalities
Best for	Testing an idea, freelancers with minimal liability exposure	Most small businesses — the default choice for liability protection without corporate complexity	Established, profitable businesses (often $60k+ net) where payroll-tax savings outweigh the admin burden

The honest breakdown: a sole proprietorship is fine for testing, but it offers zero liability protection — one lawsuit can reach your personal savings. An LLC is the right default for most new businesses: real liability protection, flexible taxation, modest formation costs in most states. An S-corp election makes sense later, once profits are high enough that the payroll-tax savings beat the extra admin costs — talk to a CPA before electing.

Form your LLC in the state where you operate. Despite the hype around Delaware, Nevada, or Wyoming, living and working in, say, California means owing California taxes plus foreign-registration fees — two states’ fees instead of one (Tailor Brands, 2026). The “cheap state” play only works for fully remote businesses.

Step 5: Register the Business and Pick a Name

Sequence matters here:

1. Check name availability. Search your Secretary of State’s business database first, then the USPTO trademark database for federal conflicts. Grab the matching domain and social handles before someone else does.
2. File with the state. LLCs file Articles of Organization; corporations file Articles of Incorporation. Sole proprietors using a trade name file a DBA (“doing business as”) with the county or state.
3. Appoint a registered agent. Required for every LLC and corporation — someone available during business hours to receive legal documents. Serve as your own agent for free, or hire a service for $100–$300/year.
4. Draft an operating agreement (LLCs) or bylaws (corporations). Not required everywhere, but it documents ownership and decision-making — banks and courts take it seriously.

Step 6: Get Your EIN — Free, Directly From the IRS

An Employer Identification Number (EIN) is your business’s federal tax ID — a nine-digit number used for tax filings, hiring employees, and opening a business bank account (IRS, August 2026).

The critical fact: an EIN is free. Any website charging $50–$300 for an “EIN filing service” is a third party with no IRS affiliation. Apply directly at IRS.gov and pay nothing (IRS, August 2026; NerdWallet, January 2026).

The online application takes about 15 minutes:

1. Apply during IRS operating hours — Monday–Friday 6:00 a.m. to 1:00 a.m. Eastern, Saturday 6:00 a.m. to 9:00 p.m., Sunday 6:00 p.m. to midnight (Fingercheck, 2026).
2. Answer the interview-style questions about your entity type and reason for applying (“started a new business”).
3. Enter the responsible party — the individual who controls the business — with a valid SSN or ITIN. Applicants without one must use Form SS-4 by fax or mail.
4. Finish in one session. The application can’t be saved and expires after 15 minutes of inactivity — have your business details ready.
5. Download the confirmation letter (CP 575) immediately. It’s your official proof of EIN for banking and licensing.

Note two limits: the IRS issues only one EIN per responsible party per day, and fax/mail applications are running slower than published timelines — apply online whenever eligible (Fingercheck, 2026). Partnerships, corporations, and multi-member LLCs must have an EIN; sole proprietors without employees can use their SSN, but most get one anyway for banking and privacy (NerdWallet, January 2026).

Step 7: Get the Licenses and Permits You Need

There is no single “business license.” Requirements stack by level — federal, state, and local — and depend on what you do and where you do it:

• Federal: Only a few industries need federal licenses — alcohol, firearms, aviation, broadcasting. Most businesses skip this layer.
• State: Many states require a general business license or tax registration, plus professional licenses for contracting, real estate, childcare, cosmetology, and similar fields. Selling taxable goods? You’ll need a seller’s permit or sales tax registration from your state tax authority — usually free or low-cost.
• Local (city/county): This is where most founders get tripped up. General business licenses typically cost $50–$200, and home-based businesses may need a home occupation permit. Check zoning before signing a lease (Homebase, September 2026; BoostSuite).

Start with the SBA’s license-and-permit lookup, then call your city clerk to confirm. Processing can take weeks — start early; this is one of the most common causes of delayed openings.

Step 8: Open a Business Bank Account (and Set Up Simple Books)

Mixing business and personal money is the fastest way to create a tax-season nightmare — and for LLC owners, commingling funds can pierce the liability protection you paid to set up. Open a separate business checking account the week you register.

What banks typically ask for: your EIN confirmation letter, state registration documents, and your operating agreement. Compare monthly fees, minimum balances, and accounting-software integrations before choosing.

Keep the books simple at the start: accounting software for invoicing and expenses (free tiers exist), a dedicated business card for all business spending — no exceptions — and 25–30% of profit set aside monthly for taxes. Self-employed founders pay quarterly estimated taxes, and the IRS charges penalties for underpayment. Track mileage and receipts from day one; receipt-scanning apps take seconds and save hours.

If revenue grows, a bookkeeper for a few hours a month is one of the highest-ROI hires you can make — and a CPA before your first full tax year is money well spent.

Step 9: Land Your First Customers

Paperwork doesn’t pay bills. Shift most of your time to revenue — the highest-leverage channels for a brand-new business:

1. Your existing network. Tell everyone what you do and who it’s for — your first five customers usually come from people who already trust you.
2. A Google Business Profile. Free, and for any local or service business the single most valuable listing you can claim. Complete every field; collect reviews from day one.
3. One content channel. Pick where your customers actually are. Post useful, specific content about the problem you solve, consistently.
4. Direct outreach. Email or message 20 ideal prospects a week with a specific, personalized offer. Uncomfortable and effective.
5. Freelance platforms. For service businesses, platforms like Upwork or Fiverr deliver early cash flow and testimonials while your own pipeline builds.

Frequently Asked Questions

How much does it cost to start a business in 2026?

A home-based service business can launch for a few hundred dollars — state LLC filing fees run $35–$500 (median ~$100), general business licenses $50–$200, and an EIN is free from the IRS (OpenChamber, October 2026; Homebase, September 2026). Product, food, or retail businesses cost far more: $8,000–$200,000+ in first-year costs once you add inventory, equipment, insurance, and a lease (Homebase, September 2026). Start lean and scale spending with revenue.

Do I need an LLC to start a business?

No — you can start as a sole proprietor with no filing at all. But a sole proprietorship offers zero separation between you and the business: your personal assets are exposed if the business is sued or can’t pay its debts. An LLC is the most popular choice because it provides liability protection with modest cost and paperwork. Testing an idea with minimal risk first, then forming an LLC once you have paying customers, is a reasonable path.

Is it really free to get an EIN?

Yes. The IRS issues EINs at no charge online, by fax, by mail, or by phone for international applicants. Any site charging $50–$300 is a third-party service with no IRS affiliation (IRS, August 2026). Apply directly at IRS.gov and you’ll receive your number immediately upon completing the online application.

How long does it take to start a business?

The legal side can move fast: an EIN takes about 15 minutes online, and many states approve LLC filings within days. Licenses and permits are the wildcard — processing can take several weeks, so apply early. Most founders can go from idea to legally operating within 3–6 weeks. Getting to consistent revenue takes longer; the BLS finds about 78% of new establishments survive their first year.

Can I start a business while working a full-time job?

Yes — many founders start as a side business to validate demand and build cash flow before giving up a paycheck. Check your employment agreement for moonlighting or non-compete clauses first, and keep business finances strictly separate from day one.

Do I need a business license for an online business?

Often, yes. There’s no federal online-business license, but your city or county may still require a general business license or home occupation permit. Selling physical goods? You’ll likely need a seller’s permit or sales tax registration where you have nexus. “Online” doesn’t mean “exempt.”

What taxes does a new small business have to pay?

At minimum, federal income tax on profits (plus state income tax in most states). Self-employed founders also pay self-employment tax — Social Security and Medicare — on net earnings, typically through quarterly estimated payments. Hiring employees adds payroll tax withholding. Set aside 25–30% of profit quarterly, and consult a CPA before your first full tax year.

Should I form my LLC in Delaware, Nevada, or Wyoming to save money?

For most small businesses, no. If you live and operate in your home state, you’ll still owe that state’s taxes and need to register as a “foreign” LLC there — two states’ fees instead of one. Form in the state where you actually do business (Tailor Brands analysis, 2026). The out-of-state strategy mainly benefits fully remote businesses or companies planning to raise venture capital (Delaware).
