Starting a business comes down to a handful of concrete steps: validating your idea, choosing a legal structure, registering with the right agencies, getting a federal tax ID, opening a business bank account, and securing any licenses you need. The whole process can take anywhere from a single afternoon for a simple sole proprietorship to several weeks for a corporation, depending on your state and business type.
Validate Your Idea Before You Invest
Before spending money on registration fees and branding, figure out whether people will actually pay for what you want to sell. This does not require a 40-page business plan. A lean startup plan, the format recommended by the SBA for early-stage businesses, focuses on a few key elements: your value proposition (what unique value you bring), your customer segments (who specifically will buy from you), your revenue streams (how you will make money), and your cost structure (the biggest expenses you will face).
Talk to potential customers. Look at competitors and study what they do well, where they fall short, and whether you can offer something meaningfully better. Search for industry trends that suggest growing or shrinking demand. The goal is to pressure-test your assumptions before you commit real dollars. If you plan to seek a bank loan or outside investors, you will eventually need a more detailed traditional business plan covering market analysis, financial projections, and a marketing strategy, but the lean version is enough to get started.
Choose a Legal Structure
Your business structure determines how much personal liability you carry, how you pay taxes, and how much paperwork you deal with. Three structures cover the vast majority of new small businesses.
Sole proprietorship. This is the default. If you start doing business without registering as anything else, you are a sole proprietor. There is no formation paperwork and no separate legal entity. The downside is that your personal assets (house, car, savings) are on the hook for any business debts or lawsuits. Sole proprietorships work best for low-risk ventures or for testing an idea before committing to a more formal structure.
LLC (limited liability company). An LLC creates a legal wall between your personal assets and your business liabilities. If the business gets sued or goes bankrupt, your personal savings and property are generally protected. Profits pass through to your personal tax return, so you avoid the double taxation that corporations face. The trade-off is that LLC members are considered self-employed and pay self-employment taxes toward Medicare and Social Security. LLCs are a strong fit for businesses with moderate to high risk, or for owners with personal assets worth protecting.
Corporation (C corp). A corporation is a fully separate legal entity with the strongest liability protection. It can sell stock, which makes raising money easier. The major drawback is double taxation: the corporation pays income tax on its profits, and shareholders pay tax again on dividends. Corporations also require more record-keeping, formal governance (board meetings, minutes, bylaws), and ongoing reporting. Most solo founders or small teams do not need a corporation unless they plan to seek venture capital or eventually go public.
Register Your Business
If you are forming an LLC, corporation, or partnership, you will need to register with the state where you do business, typically through the Secretary of State’s office or a similar business agency. Before filing, you will need a registered agent in your state. A registered agent is a person or service authorized to receive legal documents on your behalf. You can serve as your own registered agent, or you can hire a service for a modest annual fee.
State filing fees vary widely, ranging from about $35 to $500 depending on where you form your business. Processing times range from same-day to several weeks, though many states offer expedited processing for an additional fee. If you plan to operate in states beyond where you formed your business, you will need to “foreign qualify” by filing a Certificate of Authority in each additional state.
If you are using a business name that differs from your legal name or your LLC’s registered name, you may need to file a DBA (doing business as), sometimes called a trade name or fictitious name. Some states handle this at the state level, others at the county level.
Get Your Federal Tax ID
Most businesses need an Employer Identification Number (EIN) from the IRS. Think of it as a Social Security number for your business. You need it to open a business bank account, hire employees, and file business tax returns. Sole proprietors with no employees can technically use their personal Social Security number, but getting an EIN is free and keeps your SSN off more documents.
You can apply for an EIN online at IRS.gov, and you will receive it immediately. There is no fee.
Open a Business Bank Account
Separating your business and personal finances is not just good practice. For LLCs and corporations, mixing personal and business funds can undermine the liability protection your structure provides. A court could “pierce the corporate veil” and hold you personally responsible for business debts if it looks like you treated the business as an extension of your personal finances.
To open a business bank account, most banks will ask for your EIN (or SSN if you are a sole proprietor), your formation documents (articles of organization for an LLC, articles of incorporation for a corporation), any ownership agreements, and your business license if applicable. Compare banks on monthly fees, minimum balance requirements, transaction fees, and interest rates. Some banks waive monthly fees if you maintain a minimum balance, while others offer fee-free accounts for new businesses.
If you plan to accept credit card payments, you will also need a merchant services account. Pay attention to the discount rate (the percentage taken from each transaction), per-transaction fees, and any monthly minimums you must meet to avoid extra charges.
Secure Licenses and Permits
Licensing requirements depend on your industry, your state, and your city or county. A home-based freelance writer may need nothing beyond a basic business license, while a restaurant will need health permits, food handler certifications, fire inspections, and possibly a liquor license. Check your state’s business licensing portal and your local city or county government website for requirements specific to your location and industry.
Some industries are regulated at the federal level too. If you plan to sell alcohol, firearms, or tobacco, or if you are in broadcasting, transportation, or investment advising, you will need federal licenses or registrations on top of state and local ones.
Set Up Basic Accounting
From day one, track every dollar coming in and going out. Use accounting software or a simple spreadsheet, but do not rely on memory or a shoebox of receipts. You will need organized records when tax season arrives, and clean books make it much easier to understand whether your business is actually profitable.
Decide early whether you will use cash-basis or accrual-basis accounting. Cash basis records income when you receive payment and expenses when you pay them. Accrual basis records income when you earn it and expenses when you incur them, regardless of when money changes hands. Most small businesses start with cash basis because it is simpler and reflects what is actually in your bank account.
Set aside money for taxes from the start. As a sole proprietor or LLC member, no employer is withholding taxes from your income, so you will likely need to make quarterly estimated tax payments to the IRS. Missing these can result in penalties, even if you pay the full amount at year-end.
Get Insurance
Your legal structure provides some liability protection, but insurance fills the gaps. General liability insurance covers claims like customer injuries or property damage. If you provide professional services or advice, professional liability insurance (also called errors and omissions) protects you against claims of negligence or mistakes. If you hire employees, most states require workers’ compensation insurance.
The cost varies enormously depending on your industry, location, revenue, and number of employees. A solo consultant might pay a few hundred dollars a year for a basic policy, while a construction business could pay thousands. Shop quotes from multiple insurers and read what each policy actually covers before choosing the cheapest option.
What the Timeline Looks Like
A sole proprietorship with no special licensing can be up and running in a day. An LLC typically takes one to four weeks, depending on your state’s processing speed. A corporation can take longer due to the additional governance setup (bylaws, initial board resolutions, stock issuance). Factor in another few days for your bank account and any local permits. If you need industry-specific licenses, those can add weeks or even months, so research those requirements early and start the applications before you plan to open your doors.
