Maryland’s location between Washington D.C. and major East Coast markets, combined with a highly educated workforce and strong government contracting sector, makes it an attractive state for new businesses. The state offers a straightforward LLC formation process through the State Department of Assessments and Taxation (SDAT) at $100, though the $300 annual report fee is one of the highest in the nation. Maryland’s 6% flat sales tax rate is simple – no local add-ons to worry about.
That said, Maryland has some unique regulatory features. Workers’ compensation is required with just one employee (stricter than most states), the state levies both a state income tax (up to 5.75%) and a county “piggyback” income tax (2.25%-3.30%), and many industries face significant state-level licensing requirements. This guide walks you through every step using official Maryland government sources.
How to Start a Business in Maryland (Step by Step)
Step 1: Choose Your Business Structure
Your business structure determines your personal liability, tax treatment, and ongoing paperwork. The most common options in Maryland:
- Sole Proprietorship – Simplest to start, but you’re personally liable for all business debts. No state filing required (just a trade name filing if using a DBA).
- LLC (Limited Liability Company) – Most popular choice for small businesses. Protects personal assets, offers flexible tax treatment, and is straightforward to form in Maryland.
- Corporation (S-Corp or C-Corp) – More formal structure with shareholders, directors, and officers. Better for businesses seeking investors.
- Partnership – For businesses with two or more owners. Options include general partnership (GP), limited partnership (LP), or limited liability partnership (LLP).
For most small businesses, an LLC is the right choice. Maryland’s LLC formation fee is $100, but be aware of the $300 annual report – one of the higher ongoing costs among states.
Step 2: Register Your Business with the State
LLC Formation via SDAT
Maryland business entities are registered through the State Department of Assessments and Taxation (SDAT) at dat.maryland.gov. Online filings are handled through Maryland Business Express.
| Item | Cost |
|---|---|
| Articles of Organization filing fee | $100 |
| Online filing (automatically expedited) | $100 + $50 expedited = $150 |
| Same-day rush processing (add-on) | +$325 |
| Technology fee (online payments) | 3% |
| Annual Report/Personal Property Return | $300/year |
| Trade Name (DBA) registration | $25 (valid 5 years) |
How to file:
- Go to Maryland Business Express and file Articles of Organization online
- Choose a business name that includes “LLC,” “L.L.C.,” or “Limited Liability Company” – check name availability through the SDAT business entity search
- Designate a resident agent with a physical Maryland address – this can be yourself, another Maryland resident, or a registered agent service
- Pay the $100 filing fee plus $50 expedited fee ($150 total for online filing) by credit card or PayPal (3% technology fee applies)
- Online filings with expedited processing are typically completed within 7 business days
Annual Report and Personal Property Return
Maryland LLCs must file an Annual Report and Personal Property Return with SDAT each year. The filing fee is $300, due by April 15. Your first report is due the year after your LLC is formed. You can request a 60-day extension (to June 15) at no extra cost if you apply before April 15.
MarylandSaves fee waiver: Businesses that offer a qualifying retirement plan or participate in the MarylandSaves program can get the $300 annual report fee waived entirely. If you have employees and are making MarylandSaves payroll contributions, the waiver is automatic.
Operating Agreement
Maryland law does not require an LLC operating agreement, but having one is strongly recommended. It outlines member rights, profit/loss sharing, management structure, and what happens if a member leaves. Keep it with your business records – it does not need to be filed with SDAT.
Trade Name (DBA)
If you operate under a name different from your LLC’s legal name, file a Trade Name Application with SDAT ($25 filing fee). The registration is valid for 5 years and must be renewed before expiration ($25 renewal). File online through Maryland Business Express.
Federal EIN (Employer Identification Number)
After forming your LLC, apply for a free EIN from the IRS at IRS.gov. You’ll receive it immediately when applying online. You need an EIN to open a business bank account, hire employees, and file taxes.
Step 3: Get Required Licenses & Permits
County Business Licenses
Maryland does not have a single statewide general business license. Instead, business licensing happens at the county level through the Clerk of the Circuit Court. Most counties require a general business license, and some require a Trader’s License if you sell goods. Fees range from $15 to $800 depending on the county and business type (up to $2,125 in Baltimore City).
Industry-Specific Licenses
Many industries require state-level licenses from specific agencies. The Department of Labor handles HVAC contractor, cosmetology, and home improvement contractor licenses. The Maryland State Police regulates private investigators. The Maryland Department of Agriculture handles pesticide and fertilizer certifications. See our industry-specific guides below for detailed requirements.
Step 4: Register for State Taxes
Maryland State Income Tax
Maryland has a graduated state income tax with rates from 2% to 5.75% for most taxpayers. New top brackets of 6.25% and 6.50% were added for high-income earners starting in 2025.
| Taxable Income (Single) | Rate |
|---|---|
| $0 – $1,000 | 2% |
| $1,001 – $2,000 | 3% |
| $2,001 – $3,000 | 4% |
| $3,001 – $100,000 | 4.75% |
| $100,001 – $125,000 | 5.00% |
| $125,001 – $150,000 | 5.25% |
| $150,001 – $250,000 | 5.50% |
| Over $250,000 | 5.75% |
County Income Tax (“Piggyback Tax”)
In addition to the state income tax, every Maryland county and Baltimore City levies a local income tax. Rates range from 2.25% to 3.30% depending on your county of residence. Most counties charge 3.20%. This means your combined state + local income tax rate is typically 7.95% to 9.05% for most small business owners.
Maryland Sales Tax
If your business sells taxable goods or services, register for a sales tax account with the Comptroller of Maryland.
- Sales tax rate: 6% statewide (no local add-ons)
- Taxable: Most tangible goods and some services (including commercial cleaning and prepared food)
- Exempt: Most services, groceries (unprepared food), prescription medications
- Registration: Free through the Combined Registration Application (CRA)
Employer Taxes (If Hiring Employees)
If you hire employees, register with the Maryland Department of Labor and the Comptroller of Maryland for payroll taxes. The easiest way is through the Combined Registration Application (CRA), which registers you for multiple tax accounts at once.
- Unemployment Insurance (UI) Tax: New employers start at approximately 2.6% on the first $8,500 of each employee’s wages. Experience-rated range: 0.30%-7.50% (Table A for 2026).
- Withholding Tax: Register with the Comptroller to withhold both state and county income taxes from employee paychecks. You’ll receive a Central Registration Number (CRN).
Report new hires to the Maryland State Directory of New Hires within 20 days of the hire date.
Step 5: Get Business Insurance
Workers’ Compensation Insurance
Maryland requires workers’ compensation insurance for employers with one or more employees. This is one of the strictest thresholds in the country – many states don’t require it until you have 3-5 employees.
| Status | Requirement |
|---|---|
| 1 or more employees | Workers’ comp is mandatory |
| Sole proprietor with no employees | Not required (may opt in voluntarily) |
| Partners with no employees | Not required for partners themselves |
| Agricultural employers (<3 employees or <$15K payroll) | Exempt |
| Employers may NOT deduct premiums from wages | Doing so is a misdemeanor |
Penalties for non-compliance: Fines up to $25,000 (increased from $10,000 effective July 1, 2024). Corporate officers can be held personally liable. Coverage is available through private carriers or Chesapeake Employers’ Insurance Company (the state fund).
General Liability Insurance
While not always legally mandated, general liability insurance is practically essential for most businesses. Many clients, landlords, and government contracts require proof of coverage. Industry standard: $1 million per occurrence / $2 million aggregate.
