Planning
12+ months before
Validate your business idea before investing significantly
Talk to potential customers before building anything. Understand who your customer is, what problem you solve, why they'd pay for it, and who else solves it. A business plan built on assumptions that haven't been tested is a gamble.
Research your market and competitors thoroughly
Know the size of your target market, how it's currently served, what your competitive advantage is, and whether the market is growing or contracting. This shapes every strategic decision that follows.
Choose your business structure with professional guidance
The most common options are sole proprietorship, LLC, S-corporation, and C-corporation. Each has different implications for liability protection, taxes, administrative burden, and investor attractiveness. An LLC is the most common starting point for small businesses. Get advice from both an attorney and a CPA before deciding.
Understand your personal financial runway
How long can you sustain yourself without income from the business? Most businesses take 12–24 months to become profitable. Know your personal burn rate, your savings, and how long you can operate without a salary before the business must support you.
Determine your startup funding requirements and sources
Bootstrapping (using your own money), friends and family, small business loans (SBA), and outside investors are the main paths. Each has different implications for control, obligations, and risk. Don't raise more than you need, and don't give away equity prematurely.
Consult a CPA about your tax obligations as a business owner
Self-employed individuals pay both employee and employer portions of Social Security and Medicare (15.3% self-employment tax on top of income tax). You'll likely need to make quarterly estimated tax payments to avoid penalties. This is one of the most common financial surprises for new business owners.
Do not commingle personal and business finances
Mixing personal and business money in the same account undermines your liability protection (especially for an LLC), makes bookkeeping impossible, and creates accounting problems at tax time. Open a separate business bank account before your first transaction.
Undercapitalization is the leading cause of small business failure
Most businesses fail not because of a bad idea but because they run out of money before reaching profitability. Build a financial model with realistic revenue projections (be conservative) and a clear view of what happens if revenue is 50% of your projection.
Preparation
3–6 months before
Register your business entity with your state
File your Articles of Organization (LLC) or Articles of Incorporation (corporation) with your state's Secretary of State office. Filing fees are typically $50–$500 depending on the state. Some states require additional annual filings and fees.
Obtain your Employer Identification Number (EIN) from the IRS
An EIN is required to open a business bank account, hire employees, and file business taxes. It's free and can be obtained instantly at irs.gov. Even single-member LLCs benefit from having one.
Open a dedicated business checking account
Use your EIN and business registration documents to open an account in your business name. Keep all business income and expenses flowing through this account exclusively.
Draft an operating agreement (LLC) or bylaws (corporation)
An operating agreement defines ownership percentages, decision-making authority, profit distribution, and what happens if an owner wants to leave. Even a single-member LLC should have one — it reinforces the separation between you and the business.
Research and obtain all required business licenses and permits
Requirements vary by business type, state, and municipality. You may need a general business license, a professional license (if applicable), a seller's permit (if selling physical goods), and possibly zoning approval or a home occupation permit.
Set up a basic bookkeeping system from day one
Use accounting software (QuickBooks, Wave, or Xero) to track every transaction from the start. Clean books are essential for tax preparation, financial decisions, and potential investors. Retroactively reconstructing a year of transactions is expensive and error-prone.
Obtain business insurance appropriate to your risk
At minimum, consider general liability insurance. Depending on your business: professional liability (E&O), commercial property, workers' compensation (if you hire), and a business owner's policy (BOP) that bundles multiple coverages. Operating without insurance exposes your personal assets.
Set up a system for tracking business expenses
Every business expense that is ordinary and necessary for your business is potentially deductible. Home office, mileage, equipment, software, professional development, and health insurance premiums all have specific rules. Track everything from day one.
Intellectual property you create before forming the company may not belong to it
If you developed your product, brand, or technology before formally creating the business entity, you should formally assign those assets to the business through a written agreement. Without this, your personal ownership of business IP can create complications with investors or co-founders.
At the Transition
At the transition
Make your first quarterly estimated tax payment on time
If you expect to owe $1,000 or more in federal taxes, you must make quarterly estimated payments (April 15, June 15, September 15, January 15). Missing them results in penalties even if you pay in full at year end. Your CPA can calculate the right amounts.
Establish your pricing and understand your unit economics
Know your cost to deliver one unit of your product or service. Know your gross margin. Know how many units you need to sell to cover your fixed costs (break-even). Pricing based on what the market will bear — not just on cost — is a key driver of profitability.
Create a simple financial dashboard you review monthly
Track: revenue, gross margin, operating expenses, and cash balance. Knowing these four numbers monthly puts you in control of your business. Most businesses that fail do so because owners weren't watching the numbers.
Build your first real customer relationships deliberately
Your first customers are your most important — they validate your business, provide feedback that shapes your product, and become your most authentic advocates. Serve them with exceptional attention.
Set up payroll if you hire employees
The moment you have employees, payroll compliance is required: withholding federal and state income tax, Social Security, and Medicare; filing payroll tax returns; paying employer portions. Use payroll software or a payroll service — the compliance burden makes DIY risky for most small businesses.
Self-employment tax will be larger than most new owners expect
As a self-employed business owner, you pay 15.3% self-employment tax on net profit (up to the Social Security wage base) before income tax. This catches many first-year owners completely unprepared. Set aside 30–35% of every dollar of profit for taxes until your CPA gives you a more precise estimate.
After the Transition
First 30–90 days after
File your first business tax return correctly
Business tax filing depends on your entity type: single-member LLCs report on Schedule C (individual return); multi-member LLCs and S-corps have separate returns. Engage a CPA who works with small businesses — your first business return is significantly more complex than a personal return.
Review your business structure at the 12-month mark
What made sense at launch may not be optimal as your revenue grows. An S-corp election, for example, can reduce self-employment tax significantly once profit exceeds roughly $40,000–$50,000. Your CPA can advise on whether a restructure is beneficial.
Establish a retirement savings plan for yourself
Self-employed individuals have access to powerful retirement accounts: SEP-IRA (contribute up to 25% of net self-employment income), Solo 401(k) (higher contribution limits, including Roth option), and SIMPLE IRA. These reduce your taxable income while building long-term wealth.
Protect your business with a buy-sell agreement if you have partners
A buy-sell agreement specifies what happens to each owner's share if a partner dies, becomes disabled, wants to leave, or gets divorced. Without one, a deceased partner's share may go to their spouse — who becomes your new business partner.
Review and update your personal estate plan
Business ownership changes your estate planning picture significantly. Ensure your business interests are addressed in your will, and consider whether a trust structure makes sense for transferring or protecting business assets.
Mixing business and personal debt is a path to losing your liability protection
If you personally guarantee business debt, co-sign business leases, or deposit business revenue into personal accounts, you begin to erode the legal separation between you and your LLC. Courts can "pierce the corporate veil" — exposing your personal assets to business creditors — when that separation isn't maintained.

Frequently Asked Questions
Should I form an LLC or an S-corporation?
Most new small businesses start as LLCs. An LLC provides liability protection with relatively simple administration. An S-corporation is a tax election (not a separate entity type) that can reduce self-employment tax once your business profit is substantial — typically $40,000–$80,000 or more annually, depending on your specific situation. You can form an LLC and later elect S-corp tax treatment. Ask a CPA when — or whether — the S-corp election makes sense for you; it adds administrative complexity that isn't worth it at low profit levels.
What taxes do I owe as a self-employed business owner?
Self-employed individuals pay: (1) self-employment tax of 15.3% on net business profit (this covers Social Security and Medicare, which employers normally split with employees); (2) federal income tax on business profit after deductions; (3) state income tax if applicable. The self-employment tax is in addition to income tax, which is why your effective tax rate as a business owner is typically higher than you might expect. Make quarterly estimated payments to avoid penalties.
What can I deduct as a business expense?
Ordinary and necessary expenses of running your business are deductible. Common deductions include: home office (if used exclusively for business), vehicle mileage or actual car expenses, equipment and technology, business software subscriptions, professional development and books, professional services (attorney, CPA), business meals (50% deductible), health insurance premiums (if self-employed), and retirement contributions. Keep records of every expense. Your CPA will guide you on the rules for each category.
Do I need a business bank account?
Yes — always. Commingling personal and business finances is one of the most common and costly mistakes new business owners make. A separate business account is required to: maintain your LLC's liability protection, prepare accurate books and taxes, understand your actual business finances, and present credibly to lenders or investors.
How do I pay myself from my business?
It depends on your entity type. Sole proprietors and single-member LLCs take an owner's draw — you transfer money from the business account to your personal account as needed. S-corp owners must pay themselves a "reasonable salary" (subject to payroll taxes) and can take additional distributions. C-corp owners receive a salary and/or dividends. Your CPA can advise on the right structure for your situation and help you avoid IRS scrutiny for paying yourself too little (a common S-corp issue).
What insurance do I need?
At minimum: general liability insurance, which covers bodily injury and property damage claims. Depending on your business: professional liability (if you provide advice or services), commercial auto (if you use a vehicle for business), commercial property (if you have business equipment or inventory), and workers' compensation (typically required if you have employees). A business owner's policy (BOP) bundles several coverages at a discount and is a common starting point for small businesses. ---
