How to Start a Small Business in the USA: A Complete Step-by-Step Guide for 2026

Starting a small business in the United States is a goal many people share, but the process can feel overwhelming when you’re not sure where to begin. The good news is that the path is clearer than ever, especially with recent changes that have simplified some of the paperwork that used to worry new entrepreneurs. According to information, the national average cost to form a limited liability company across all states is approximately $219.15, combining initial and recurring state fees.

That figure doesn’t include other startup expenses like equipment, inventory, or insurance, but it gives you a realistic starting point. This guide walks you through each essential stage: choosing your business structure, registering your name, obtaining licenses, understanding taxes, and setting up your finances. Whether you’re launching a local service business, an online store, or a consulting practice, these fundamentals apply. The key is to move through each step methodically and get professional help when your situation involves complexity.

Choose the Right Business Structure

Your business structure shapes everything how much you pay in taxes, how much personal risk you carry, and how much ongoing paperwork you’ll handle. This is the first decision you’ll make, and it’s worth getting right.

Sole Proprietorship is the simplest and least expensive option. You and the business are legally the same entity. You report business income on your personal tax return using Schedule C. However, this structure offers no liability protection your personal assets are fully exposed if the business faces legal claims or debts. This works for very low-risk ventures or testing a business idea, but it’s rarely suitable for long-term operations.

Limited Liability Company (LLC) is the most popular choice for small businesses. It provides liability protection your personal assets are generally shielded from business debts and lawsuits while maintaining pass-through taxation by default. Profits and losses flow to your personal tax return. An LLC is formed by filing Articles of Organization with your state and offers flexibility in management and ownership. For most small businesses, an LLC represents the best balance of protection and simplicity.

C Corporation is the standard corporate structure. The corporation pays taxes at the entity level (currently 21% federal rate), and shareholders pay tax again on dividends known as double taxation. C corps are required if you plan to raise venture capital or eventually go public. They involve significant compliance requirements: a board of directors, shareholder meetings, bylaws, and detailed record-keeping.

S Corporation is not an entity type but a tax election made with the IRS using Form 2553. An LLC or corporation can elect S corp status to avoid double taxation and potentially reduce self-employment taxes. However, strict requirements apply: a maximum of 100 shareholders, all must be U.S. citizens or residents, and only one class of stock is permitted.

Pick a Business Name and Register It

Your business name is how customers find you and how you’ll be legally identified. Before committing, verify that the name is available.

Start by searching your state’s business database through the Secretary of State’s office. Avoid names that are confusingly similar to existing registered businesses. Next, check the federal trademark database through the United States Patent and Trademark Office even if your state approves the name, a prior federal trademark could force you to rebrand later.

If you plan to operate under a name different from your legal entity name, you’ll typically need to file a DBA (Doing Business As), sometimes called a fictitious business name or trade name, with your state or local government. Requirements vary by jurisdiction.

For your domain name, check availability before you commit to branding. Even if you’re not ready to build a website, securing a relevant domain is wise.

Register Your Business with the Appropriate Agencies

Registration requirements depend on your structure and location. For most small businesses, registration involves state and local governments, with some federal requirements depending on your activities.

Federal registration starts with obtaining an Employer Identification Number (EIN) from the IRS. An EIN is a federal tax ID that most businesses need even those without employees to open a bank account and file taxes. Applying for an EIN is free and can be done online through the IRS.

State registration applies to formal entities like LLCs and corporations. You file formation documents Articles of Organization for an LLC or Articles of Incorporation for a corporation with your Secretary of State’s office and pay a filing fee. You’ll also need a registered agent: a person or company authorized to receive legal documents on behalf of your business, with a physical address in the state of registration.

If you operate in multiple states, you may need to file for foreign qualification in each additional state where you do business. This notifies the state that your out-of-state business is active there and typically involves additional fees and annual reporting requirements.

Obtain Required Licenses and Permits

The United States does not have a single national business license. Instead, requirements come from federal, state, county, and city levels and they depend heavily on what your business does and where it operates.

General business licenses are often required at the local level. Cities and counties issue these for operating within their jurisdiction. If you have multiple locations, you may need a separate license for each one.

State-level licenses apply to many industries. States tend to regulate a broader range of activities than the federal government. Commonly regulated activities include construction, plumbing, restaurants, retail, vending machines, auctions, dry cleaning, and farming. Professional and occupational licenses are required for regulated professions such as healthcare, law, accounting, real estate, and insurance.

Federal licenses are required for specific industries. According to the Small Business Administration, these include agriculture, alcoholic beverages, aviation, firearms and explosives, fish and wildlife, commercial fisheries, maritime transportation, mining and drilling, nuclear energy, radio and television broadcasting, and transportation and logistics. If your business falls into one of these categories, you’ll need federal approval in addition to state and local requirements.

Sales tax permits are required if you sell taxable goods or services. You register with your state’s department of revenue to collect and remit sales tax.

The SBA recommends checking with your Secretary of State’s website to identify which permits and licenses your specific business needs. Some licenses expire after a set period, so tracking renewal deadlines is essential.

Understand Your Tax Obligations

Taxes are a critical consideration for any new business. The IRS identifies several types of business taxes that may apply.

Income tax applies to all businesses except partnerships, which file information returns. Pass-through entities sole proprietorships, partnerships, LLCs, and S corporations report income on the owners’ personal returns. The federal individual income tax rates for the 2025 tax year range from 10% to 37%, depending on income level and filing status.

Self-employment tax covers Social Security and Medicare for individuals who work for themselves. According to the Social Security Administration’s 2026 fact sheet, the self-employed tax rate remains at 15.30% for 2026. This applies to net earnings from self-employment.

Payroll tax applies when you have employees. Employers must pay their share of Social Security and Medicare taxes, and unemployment and workers’ compensation taxes may also apply.

Excise tax applies to specific goods, services, and activities, such as fuel, tobacco, airline tickets, and gasoline sales.

Capital gains tax applies when you sell business assets. Assets held for more than a year are taxed at capital gains rates of 0%, 15%, or 20%, depending on total income. Short-term gains are taxed as ordinary income.

For estimated tax payments, the IRS recommends that business owners generally pay taxes on income through regular quarterly estimated payments. As a practical guideline, setting aside 30 to 40 percent of net income for federal and state tax obligations is a reasonable approach.

Open a Business Bank Account

Separating your business and personal finances is essential especially if you’ve formed an LLC or corporation. Commingling funds can undermine your liability protection and create accounting headaches.

Before applying, gather the necessary documents. Most banks will ask for your EIN confirmation letter, formation documents (Articles of Organization or Incorporation), a government-issued photo ID for each owner or authorized signer, and possibly an operating agreement or bylaws.

Because of anti-money-laundering rules, banks also need to know who owns or controls the business typically anyone with 25% or more ownership or significant control. You’ll be asked to list these individuals and provide their identification. Note that while U.S. companies are no longer required to report beneficial ownership information directly to FinCEN, banks still collect this information for their own compliance purposes.

When choosing a bank, compare monthly fees, transaction limits, wire fees, and online banking quality. Traditional banks offer branch access and in-person support. Online-first banks and fintechs often provide faster onboarding and lower fees. Credit unions and community banks may be more flexible with smaller businesses.

Once your account is open, run all business income and expenses through it. This separation simplifies tax preparation and provides a clear financial record.

Consider Financing Options

Not every business needs outside funding. Many start with personal savings, revenue from early customers, or support from friends and family. If you do need capital, several options exist.

SBA 7(a) loans are the Small Business Administration’s primary loan program. The maximum loan amount for a single 7(a) loan is $5 million. These loans can be used for working capital, real estate, equipment, refinancing debt, and more. To be eligible, businesses must operate for profit, be located in the U.S., meet SBA size standards, and demonstrate the ability to repay.

SBA 504 loans provide long-term, fixed-rate financing for major fixed assets like real estate and equipment. The maximum 504 loan amount is $5.5 million. These are available through Certified Development Companies, which are nonprofit partners of the SBA.

An important update for 2026: Effective July 4, 2026, the SBA clarified that eligible borrowers can combine 7(a) and 504 financing for up to $10 million in total SBA-backed funding. Under the new policy, a borrower can access up to $5 million through 7(a) and up to $5 million through 504, as long as the structure and use of funds meet SBA requirements. This represents a significant increase from the previous cumulative limit of $5 million.

Microloans are smaller SBA-backed loans, typically up to $50,000, available through nonprofit intermediaries. The average microloan is about $13,000, and most interest rates fall between 8% and 13%, with repayment terms up to seven years, These work well for very small businesses and startups with modest needs.

Grants exist but are less common than loans. Most government grants target specific industries, demographics, or purposes. Grants.gov is a source for federal grant opportunities, and local chambers of commerce or Small Business Development Centers may have information on available grants.

Stay Compliant After Launch

Compliance is ongoing. Once your business is up and running, several recurring obligations require attention.

Annual reports are required in most states for LLCs and corporations. Deadlines and fees vary, and missing them can result in penalties or administrative dissolution. Set calendar reminders for your state’s requirements.

License renewals follow different schedules depending on the license type and jurisdiction. Some are annual, some biennial. Failing to renew can mean fines or suspension of your ability to operate.

Tax filings continue on quarterly and annual schedules. Estimated payments, payroll taxes, sales tax remittance, and annual returns all have their own deadlines.

Registered agent services must remain active. If you change your registered agent or business address, file the appropriate updates with your state.

An important update on beneficial ownership reporting: On August 11, 2026, FinCEN issued a final rule permanently removing the requirement for U.S. companies and U.S. persons to report beneficial ownership information under the Corporate Transparency Act. The rule became effective August 14, 2026. U.S. companies are no longer required to file BOI reports, and U.S. persons do not need to provide BOI as beneficial owners or company applicants.

FinCEN has also announced it will delete previously reported information that relates to U.S. companies and U.S. persons from its database. Certain foreign entities registered to do business in the U.S. may still have reporting obligations, but for the vast majority of American small businesses, this reporting requirement is now permanently behind us.

The first year involves the steepest learning curve. Once you have systems in place accounting software, a deadline calendar, and a relationship with a tax professional compliance becomes routine rather than overwhelming.
