Pro Tip
Write a Business Plan
Draft a business plan before seeking any financing. Banks, SBA lenders, and angel investors in Massachusetts all require a written plan with financial projections before approving funding.
Your plan should include a market analysis, revenue model, startup cost breakdown, and 12-month cash flow forecast. Follow our step-by-step business plan guide for a template that matches what lenders expect.
Pro Tip
Choose Your Business Structure in Massachusetts
Most founders in Massachusetts choose an LLC because it combines personal liability protection with pass-through taxation. Filing an LLC costs $500 at the Massachusetts Secretary of the Commonwealth.
The four main structures are sole proprietorship, LLC, S-Corp, and C-Corp. Each has different tax treatment, liability exposure, and paperwork requirements. See the full comparison below, or read our Massachusetts LLC formation guide for a detailed walkthrough.
Pro Tip
Business Structure Comparison — Massachusetts
Full comparison guide| Structure | Massachusetts Filing Cost | Personal Liability | How You're Taxed | Best For |
|---|---|---|---|---|
| Sole Proprietorship | $65 (DBA) | ❌ None | Personal income tax. No separate return. | Freelancers, consultants, side hustles testing an idea with no employees. |
| LLC Most Common | $500 online | ✅ Personal assets protected | Pass-through by default. Elect S-Corp when profitable. | Most small businesses. Best balance of liability protection, flexibility, and tax options. |
| S-Corporation | ~$500 + IRS election | ✅ Personal assets protected | Pass-through. Owners pay themselves a salary — can reduce self-employment tax. | Profitable businesses (typically $50K+ net) where payroll tax savings justify the complexity. |
| C-Corporation | $275 | ✅ Personal assets protected | Corporate tax rate (21% federal). Double taxation on dividends. | Startups planning to raise VC funding, issue stock options, or eventually go public. |
| General Partnership | Free / No State Filing | ❌ None — all partners personally liable | Pass-through. Each partner reports share on personal return. | Two or more owners who trust each other and don't need liability protection. |
Which should you choose? Most first-time founders in Massachusetts pick an LLC — it protects your personal assets without the complexity of a corporation. If you're not sure, consult a CPA or business attorney before filing. Read the full Massachusetts LLC guide →
