How to Start a Small Business in the US: A Practical Checklist
Published July 31, 2026 · By the LaunchKit team
Quick answer: Start with the customer and the numbers, then choose a structure, register where required, obtain the right tax IDs and licenses, separate the money, arrange insurance, and create a basic recordkeeping routine. The order matters because later applications often depend on decisions made earlier.
Starting a business can feel like twenty unrelated jobs arriving at once. The useful way to handle it is to turn the work into a sequence. This guide gives you that sequence without pretending every state, city, or industry has the same rules.
1. Define the offer and the customer
Write down what you sell, who buys it, the result they receive, and what they are likely to compare you with. Speak to potential customers before spending heavily on branding or equipment. The SBA business guide recommends market research and competitive analysis before launch because demand, location, saturation, and prevailing prices affect whether the idea works.
2. Estimate startup costs and a minimum viable price
List one-time costs, monthly overhead, direct costs per job or sale, owner pay, taxes, and a contingency. Then calculate how many sales you need to cover them. A competitor's price is useful market evidence, but it is not a substitute for your own cost calculation.
3. Choose a business structure
Your structure affects liability, taxes, paperwork, and how you raise money. Common choices include sole proprietorship, partnership, LLC, and corporation. Rules vary by state, so use the SBA structure comparison as a starting point and get professional advice when the liability or tax consequences are material.
4. Choose and check the name
Check the relevant state business registry, local requirements, domain availability, and trademark conflicts before ordering signs or printing documents. A business name, a state entity registration, a domain, and a federal trademark are different things.
5. Register the business where required
Registration depends on structure and location. An LLC or corporation is generally formed with a state before applying for an EIN. A sole proprietor may still need a fictitious-name filing, local registration, or industry permit. Record the filing date, renewal date, registration number, and login location in one place.
6. Get tax IDs and understand the tax calendar
The IRS explains the federal starting points on its Starting a business page. Depending on your structure and activities, you may need an EIN, state tax accounts, sales-tax registration, payroll accounts, or estimated-tax planning. State requirements must be checked with the relevant state authority.
7. Check licenses, permits, zoning, and insurance
Requirements depend on the work, the location, and government rules. Check federal, state, county, and city requirements rather than relying on a generic list. Some activities need professional or occupational licensing, and home-based businesses can still face zoning or permit rules.
Insurance is a separate decision. Consider the risks created by your premises, vehicle, advice, products, employees, client property, and data. Ask an appropriately licensed insurance professional what applies to the business you actually run.
8. Separate business money and create records
Open an appropriate business bank account and decide how income, expenses, receipts, invoices, mileage, assets, and owner draws will be recorded. The IRS recordkeeping guidance says the system may be any method suited to the business, provided it clearly shows income and expenses and retains supporting documents.
9. Prepare the customer-facing paperwork
Before the first job, prepare the documents that remove ambiguity: quote or estimate, scope of work, invoice, payment terms, cancellation language, intake form, and a simple complaint or issue log. The exact set depends on the business and state law. Templates are a starting framework, not a substitute for legal review.
10. Launch a small, measurable version
Start with a defined offer, a clear price, one acquisition channel, and a simple weekly review. Track inquiries, conversion, average sale, direct cost, time spent, and cash collected. The first goal is not to look large. It is to learn what customers buy while the system is still easy to change.
Your first-week file
Keep one startup file containing registrations, tax IDs, license evidence, insurance documents, bank details, price calculations, document templates, renewal dates, and professional-adviser notes. That file turns internal panic into a list you can actually manage.
This is general educational information, not legal, tax, accounting, licensing, or insurance advice. Requirements vary by state, locality, industry, and business structure. Verify current rules with the responsible government agency and qualified advisers.
