By Jake Lawson, LLC Formation Strategist
New Hampshire entrepreneurs considering a sole proprietorship, let’s have an honest conversation. After helping 200+ New Hampshire business owners structure their businesses properly, I’m sharing the unfiltered truth: sole proprietorships are legal liability traps disguised as simple business structures.
Bottom line first: While New Hampshire makes sole proprietorships extremely easy to start, they expose you to unlimited personal liability while offering zero business credibility. For just $139 total, you can get a New Hampshire LLC with identical tax treatment plus crucial asset protection.
What Is a New Hampshire Sole Proprietorship? (The Reality)
A sole proprietorship in New Hampshire automatically exists the moment you start doing business activities with the intent to make a profit. No paperwork, no state filing, no protection.
Formation requirement: Start doing business
State filing: None
Liability protection: Zero
Business credibility: Minimal
Jake’s reality check: “Easy to start” often means “expensive problems later.”
The Brutal Truth About Sole Proprietorship Liability
Unlimited Personal Liability
As a sole proprietor, you and your business are legally the same entity. This means:
- Your personal assets are business assets: House, car, savings, investments—all at risk
- Business debts become personal debts: Creditors can pursue your personal property
- Lawsuits target you personally: No business entity to provide a liability shield
- Professional mistakes affect your personal life: One business error can cost you everything
Real-World New Hampshire Scenario
Example: You run a home renovation business as a sole proprietorship. A customer slips on your ladder and suffers a serious injury. The lawsuit for $300,000 can force you to sell your Portsmouth home to pay the judgment—even if you had proper insurance, it might not cover everything.
Jake’s experience: I’ve seen New Hampshire entrepreneurs lose their family homes because they chose convenience over protection.
New Hampshire Sole Proprietorship Advantages (The Sales Pitch)
Simplicity of Formation
What they tell you: No paperwork required, instant business creation.
What they don’t tell you: This “advantage” disappears the moment you need business banking, credibility, or protection.
Tax Simplicity
What they tell you: File business income on your personal tax return (Schedule C).
What they don’t tell you: New Hampshire LLCs have identical tax treatment for single-member businesses.
Low Initial Cost
What they tell you: Start for free (plus any required licenses).
What they don’t tell you: The hidden costs come later through liability exposure and business limitations.
The Real Disadvantages (Why I Never Recommend Them)
1. Zero Liability Protection
The problem: Your personal assets pay for business problems.
New Hampshire reality: Live Free or Die doesn’t include dying financially from business liability.
2. Credibility Nightmare
Banking difficulties: Many banks prefer formal business entities
Vendor relationships: Suppliers often require corporate entities
Customer perception: “John Smith Home Repair” vs. “Smith Home Solutions LLC”
3. Growth Limitations
No business credit: Everything runs through your personal credit
Investment challenges: Investors prefer formal business structures
Partnership difficulties: Adding partners requires business restructuring
4. Tax Complications
Self-employment tax: 15.3% on all business income (same as LLC)
Limited deductions: Fewer business expense options
Audit risk: Schedule C filers face higher IRS scrutiny
5. Estate Planning Problems
Business dies with you: No business continuity planning
Family complications: Business assets entangled with personal estate
Succession impossibility: Can’t transfer a sole proprietorship
New Hampshire Sole Proprietorship Requirements
Automatic Requirements
- Start doing business: That’s it—you’re now a sole proprietor
- Use your legal name: Default business name is your full legal name
Practical Requirements (For Real Operations)
- Trade Name (DBA): Required if using any name other than your legal name
- EIN from IRS: Recommended for banking and vendor relationships
- Business licenses: Based on your industry and location
- Business insurance: Essential given unlimited liability exposure
Step-by-Step New Hampshire Sole Proprietorship Setup
Step 1: Business Planning (Think This Through)
Consider these factors:
- Liability risk of your business activity
- Personal assets you’re putting at risk
- Professional credibility requirements
- Growth and investment plans
Jake’s warning: If you answer “high risk,” “significant assets,” “important,” or “aggressive growth” to any of these, stop here and form an LLC instead.
Step 2: Trade Name Registration (If Needed)
When required: Using any name other than your full legal name
New Hampshire process: File Application for Registration of Trade Name
Cost: $50 filing fee
Filing options: Online through NH QuickStart or by mail
Example: Sarah Johnson wants to operate “Granite State Consulting” instead of “Sarah Johnson”—trade name registration required.
Step 3: Obtain EIN (Highly Recommended)
Why get an EIN:
- Protect your Social Security number
- Required for business banking
- Needed for hiring employees
- Professional credibility with vendors
Process: Free through IRS website (15 minutes)
Jake’s advice: Always get an EIN, even if not legally required.
Step 4: Business Licenses and Permits
New Hampshire advantage: No general state business license required
Still need to check:
- Local city/county business licenses
- Industry-specific professional licenses
- Sales tax registration (if applicable)
- Health department permits (food service, etc.)
Step 5: Business Banking and Insurance
Banking requirements:
- Photo ID
- EIN confirmation letter
- Trade name certificate (if applicable)
- Business formation documents (you won’t have any)
Insurance needs (critical for sole proprietors):
- General liability insurance
- Professional liability (if applicable)
- Business property insurance
- Workers’ compensation (if hiring employees)
New Hampshire Sole Proprietorship Taxes
Federal Tax Treatment
- Schedule C: Report business income/expenses on personal return
- Form 1040: Include business activity with personal taxes
- Self-employment tax: 15.3% on business income
- Quarterly payments: Required if owing $1,000+ annually
New Hampshire State Taxes
- No state income tax: Major New Hampshire advantage
- Business profits tax: Only if net business income exceeds $50,000
- Business enterprise tax: Only if business enterprise value base exceeds $75,000
Jake’s analysis: New Hampshire’s tax advantages are real, but they apply equally to LLCs.
New Hampshire LLC vs Sole Proprietorship: The Real Comparison
| Factor | Sole Proprietorship | New Hampshire LLC |
| Liability Protection | None—unlimited personal liability | Full protection for personal assets |
| Formation Cost | $50 (if DBA needed) | $139 ($39 service + $100 state fee) |
| Annual Requirements | None | $100 annual report |
| Tax Treatment | Schedule C on personal return | Identical for single-member LLCs |
| Business Credibility | Low—just a person doing business | High—formal business entity |
| Banking Ease | Difficult—many banks prefer entities | Easy—banks understand LLCs |
| Growth Flexibility | Limited—no business structure | Flexible—can add members, investors |
| Estate Planning | Complicated—dies with you | Simple—business continues |
Jake’s bottom line: For $89 more upfront ($139 vs $50), you get massive liability protection, business credibility, and operational flexibility. This is the easiest decision in business.
When Sole Proprietorships Might Make Sense (Very Rare)
Ultra-Low-Risk Activities
- Freelance writing with comprehensive insurance
- Online consulting with professional liability coverage
- Low-value product sales with minimal customer interaction
Temporary Testing Phases
- Market validation for 30-60 days maximum
- Very small side hustles under $5,000 annually
- Immediate transition planned to formal entity
Jake’s reality: Even these scenarios benefit from LLC protection. I can count on one hand the times I’ve recommended sole proprietorships over 15 years of practice.
Converting from Sole Proprietorship to LLC (The Nightmare)
What’s Involved
- Form the LLC: File Certificate of Formation
- Transfer assets: Move business assets to LLC
- Update banking: Close sole proprietorship accounts, open LLC accounts
- Notify vendors: Update all business relationships
- Revise contracts: Renegotiate existing agreements
- Update marketing: Change all business materials
- Tax adjustments: Handle tax year transition issues
- License transfers: Reapply for business licenses under LLC
Time investment: 20-40 hours of administrative work
Professional costs: $500-2,000 in accounting and legal fees
Business disruption: 2-4 weeks of operational complications
Jake’s advice: This conversion headache alone justifies starting with an LLC.

Bottom Line: My New Hampshire Recommendation
For 95% of New Hampshire entrepreneurs: Form a New Hampshire LLC instead of a sole proprietorship. The minimal additional cost provides massive liability protection and business credibility benefits that pay for themselves immediately.
For the 5% exception: If you absolutely cannot afford the $139 LLC cost and are starting an ultra-low-risk business for immediate income, sole proprietorship might work temporarily—but plan your LLC conversion from day one.
Strategic advice: New Hampshire’s “Live Free or Die” motto shouldn’t include dying financially from easily preventable business liability. Protect your personal assets while maintaining the tax advantages you want.
The smart play: Take advantage of New Hampshire’s business-friendly environment and lack of state income tax by forming an LLC that protects your wealth while allowing you to build it.
