By Jake Lawson, LLC Formation Strategist & Tax Advisor
Thinking about launching a sole proprietorship in Maryland? Before you make that decision, let me share some reality-based insights from 15 years of helping entrepreneurs navigate this exact choice.
Maryland is actually one of the more sole proprietorship-friendly states—no mandatory business licensing, reasonable DBA fees at $25, and LLC formation costs only $150. But here’s the thing: just because something is easier doesn’t mean it’s smarter.
After guiding over 1,200 business launches, I’ve seen too many Maryland entrepreneurs choose sole proprietorships for short-term convenience and pay for it with long-term headaches. Let me break down what you’re really signing up for.
What Is a Maryland Sole Proprietorship?
A sole proprietorship in Maryland is the business equivalent of working without a safety net—you’re operating under your personal name with zero separation between your business and personal assets.
The moment you start any revenue-generating activity in the Old Line State—whether that’s freelance consulting from your Baltimore rowhouse or selling crafts at the Annapolis farmers market—you’re automatically operating as a sole proprietor. No paperwork required, no state filings, no waiting periods.
It’s the default business structure for anyone working alone, which makes it both the most common and often the most regretted choice among my clients.
The Sole Proprietorship Advantages (The Short List)
Instant Business Launch
You can literally start earning money today. No state approval process, no formation documents, no waiting for bureaucratic wheels to turn. Have an idea? Congratulations, you’re in business.
Streamlined Tax Process
Business income flows directly to your personal tax return via Schedule C. If you’re already filing Maryland state taxes, this adds minimal complexity to your annual routine.
Minimal Upfront Investment
A basic sole proprietorship costs essentially nothing to start. Even if you add a DBA ($25) and basic business banking, you’re looking at under $100 total startup costs.
The Sole Proprietorship Disadvantages (The Reality Check)
Complete Personal Asset Exposure
This is the killer issue, especially in Maryland’s litigious business environment around DC and Baltimore.
If your business faces a lawsuit—client injury, contract dispute, professional errors, even frivolous claims—your personal assets are completely exposed. That includes your house (whether it’s a $200K townhouse in Frederick or a $600K home in Montgomery County), your car, savings, retirement accounts, everything.
I’ve watched Maryland contractors lose personal homes over business disputes. It’s brutal and completely preventable.
Professional Credibility Gap
Try pitching services to Lockheed Martin, Johns Hopkins, or the federal government as “Jennifer Smith Consulting” versus “Chesapeake Strategic Solutions LLC.” The credibility difference is massive and affects your ability to land quality contracts.
This perception issue extends beyond Fortune 500 clients—it impacts banking relationships, vendor credit terms, insurance coverage, and even customer trust.
The Conversion Maze
Converting from sole proprietorship to LLC later isn’t a simple form change—it’s essentially shutting down one business and starting another. In Maryland, this means:
- Filing new LLC Articles of Organization with SDAT
- Obtaining new federal EIN
- Transferring or canceling existing contracts
- Updating all banking and vendor relationships
- Re-applying for business licenses and permits
- Revising insurance policies and coverage
I’ve had Maryland clients spend 3-6 months untangling this mess when they could have started with the right structure from day one.
Maryland’s Business-Friendly Environment (Why LLCs Make More Sense)
Maryland offers one of the more reasonable LLC environments on the East Coast:
LLC Formation Cost: $150 (compare to $520 in Massachusetts or $300+ in New York) Annual Requirements: $300 personal property return (applies to sole proprietorships too) No Publication Requirements: Unlike New York, you don’t need expensive newspaper publications Registered Agent Options: You can serve as your own registered agent or hire a service
With such reasonable LLC costs, the decision becomes: why risk everything to save $150?
Sole Proprietorship vs. LLC: The Maryland Numbers
| Factor | Sole Proprietorship | Maryland LLC |
| State Filing Fee | $0 | $150 |
| Personal Asset Protection | None | Complete protection |
| Business Credibility | Low | High |
| Tax Complexity | Simple (Schedule C) | Same for single-member LLCs |
| Annual State Requirements | Personal property return | Personal property return |
| Banking/Credit | Difficult | Easy |
| Total Year 1 Cost | $0-50 | $150-300 |
My analysis: For $150, you get liability protection that could save your financial future. In Maryland’s business environment, that’s the bargain of the century.
How to Start Your Maryland Sole Proprietorship (Step-by-Step)
If you’re determined to go the sole proprietorship route despite my warnings, here’s how to do it properly:
Step 1: Business Foundation Work
Before you touch any paperwork, establish these fundamentals:
Business Model Definition: Clearly define how you’ll generate revenue. This isn’t just for planning—it affects everything from insurance needs to tax deductions.
Target Market Analysis: Who are your customers? Maryland’s diverse economy—from DC metro federal contractors to Baltimore tech companies to Eastern Shore tourism businesses—offers different opportunities and risks.
Financial Planning: Map out startup costs, operating expenses, and revenue projections. Many sole proprietors underestimate costs and run into cash flow problems within the first year.
Business Address Selection: Choose a primary address for all business correspondence. This can be your home address, but consider privacy implications—this may appear on contracts and public records.
Step 2: Choose Your Business Name Strategy
You have two options in Maryland:
Option 1: Operate Under Your Legal Name
- Default choice for sole proprietorships
- Zero additional cost or paperwork
- Simple but limits branding opportunities
Option 2: Register a Trade Name (DBA)
- Allows branded business name
- $25 filing fee with Maryland SDAT
- Better for marketing and professional credibility
How to Register a Trade Name in Maryland
Online Filing: Use Maryland Business Express for fastest processing Paper Filing: Submit Trade Name Application by mail Processing Time: 7-10 business days Cost: $25
Required Information:
- Your legal name and address
- Desired trade name
- Business activity description
- Signature and date
Step 3: Obtain Your Federal EIN
While Maryland doesn’t require an EIN for sole proprietorships, I strongly recommend getting one:
Identity Protection: Keep your Social Security Number off business documents, contracts, and public filings.
Banking Requirements: Most Maryland banks require an EIN for business accounts, even for sole proprietorships.
Professional Appearance: Using an EIN on invoices and contracts looks more professional than your SSN.
Future Flexibility: If you ever hire employees or convert to an LLC, you’ll need an EIN anyway.
How to Apply: Go directly to the IRS website (irs.gov) and apply online. It’s free and takes about 10 minutes. Avoid third-party services charging $50-200 for something the IRS provides at no cost.
Step 4: Research Business License Requirements
Good news: Maryland doesn’t require a general business license for sole proprietorships at the state level.
However, you may need:
- Industry-specific licenses (professional services, food handling, construction)
- Local business licenses (varies by county and municipality)
- Federal licenses (for certain regulated industries)
Research Resources:
- Maryland OneStop Licensing Portal – comprehensive license finder
- Your county/city business licensing office
- Professional licensing boards (for regulated professions)
Common Maryland License Requirements:
- Baltimore City: Business license required for most businesses
- Montgomery County: Home-based business permits
- Prince George’s County: Business licenses for certain activities
- Anne Arundel County: Various permits depending on business type
Step 5: Set Up Business Banking
Separating business and personal finances is crucial, even as a sole proprietor.
What Maryland Banks Typically Require:
- Photo ID (driver’s license or passport)
- Social Security Number or EIN
- Trade Name certificate (if you registered one)
- Initial deposit (varies by bank, typically $25-100)
Banking Tips for Maryland Sole Proprietors:
- Shop around: Fees vary significantly between banks
- Consider credit unions: Often better terms for small businesses
- Ask about business services: Credit cards, loans, merchant services
- Understand fee structures: Monthly maintenance, transaction limits, overdraft policies
Recommended Maryland Banks for Small Businesses:
- M&T Bank: Strong local presence, good small business support
- PNC Bank: Comprehensive business services
- First National Bank of Maryland: Local focus, competitive rates
- Navy Federal Credit Union: If you qualify for membership
Maryland Tax Obligations for Sole Proprietors
Federal Tax Requirements
Schedule C: Report business income and expenses on your personal tax return (Form 1040).
Self-Employment Tax: Pay both employer and employee portions of Social Security and Medicare taxes (15.3% on net earnings over $400).
Quarterly Estimated Taxes: If you expect to owe $1,000+ in taxes, make quarterly payments to avoid penalties.
Maryland State Tax Considerations
Maryland Income Tax: Business profits are taxed as personal income at Maryland rates (2.25% to 5.75% depending on income level).
Personal Property Tax: Maryland requires businesses to file annual personal property returns for business assets. This applies to both sole proprietorships and LLCs.
Sales Tax: If you sell taxable goods or services, register with the Maryland Comptroller for sales tax collection and remittance.
County Taxes: Some Maryland counties impose additional business taxes or fees.
Industry-Specific Considerations in Maryland
Federal Contracting (DC Metro Area)
The DC area offers massive opportunities for government contractors, but federal agencies increasingly require vendors to have formal business structures and comprehensive insurance coverage.
Healthcare/Biotech (Baltimore/Rockville)
With Johns Hopkins, NIH, and numerous biotech companies, Maryland has a thriving healthcare sector. Professional liability exposure makes LLC protection almost essential.
Technology Services
Maryland’s growing tech sector demands credibility and protection. Major clients expect to work with formal business entities, not individual sole proprietors.
Professional Services
Lawyers, accountants, consultants, and other professionals face significant liability exposure. Many professional liability insurance policies offer better coverage for LLCs than sole proprietorships.
Common Maryland Sole Proprietorship Mistakes
After helping hundreds of Maryland entrepreneurs, I see these errors repeatedly:
Mistake #1: Assuming “Simple” Means “Better”
Simple formation doesn’t mean simple operations. You still need proper contracts, insurance, accounting systems, and legal compliance.
Mistake #2: Ignoring Local Requirements
Maryland’s 23 counties and numerous municipalities each have their own business requirements. Don’t assume that no state license means no licensing requirements at all.
Mistake #3: Mixing Personal and Business Finances
This creates tax nightmares and weakens any liability protection you might get through insurance or other means.
Mistake #4: Underestimating Insurance Needs
Without LLC protection, business insurance becomes your only shield against liability. Many sole proprietors carry inadequate coverage or skip it entirely.
When to Convert from Sole Proprietorship to LLC
Several situations should trigger serious consideration of LLC conversion:
Revenue Milestones: Once you’re generating $50,000+ annually, the liability protection becomes critical.
Client Requirements: Many larger Maryland employers and government agencies prefer or require working with formal business entities.
Asset Accumulation: As your personal wealth grows (especially real estate in Maryland’s appreciating market), protection becomes more valuable.
Growth Plans: If you’re considering hiring employees, bringing on partners, or seeking investment, you’ll need a formal business structure.
Industry Risk: Any business with potential liability exposure should consider LLC protection early.
My Honest Recommendation for Maryland Entrepreneurs
After 15 years in this business, here’s my straight talk on Maryland sole proprietorships:
Consider sole proprietorship if:
- You’re testing a very low-risk business idea (under $25K annual revenue)
- You absolutely cannot afford the $150 LLC filing fee
- You plan to convert to LLC within 6-12 months
- Your business has minimal liability exposure
Choose LLC if:
- You’re serious about building a sustainable business
- You have any meaningful liability exposure
- You want credibility with clients and vendors
- You can afford the modest additional investment
Given Maryland’s reasonable LLC fees and business-friendly environment, the choice seems clear to me. The $150 investment in LLC protection is one of the best insurance policies you can buy.
Step-by-Step LLC Alternative
If my arguments have convinced you to consider an LLC instead, here’s the streamlined path in Maryland:
- Choose and verify your LLC name (check availability through Maryland SDAT)
- File Articles of Organization ($150 fee online through Maryland Business Express)
- Create an Operating Agreement (even single-member LLCs should have one)
- Obtain your EIN (free from IRS website)
- Open business banking (easier with LLC documentation)
- Register for any required licenses (same process as sole proprietorships)
Total time: 2-3 weeks. Total additional cost over sole proprietorship: $150. Total protection gained: potentially millions in personal assets.
