Maryland business license guide
Last updated: August 1, 2026
Maryland does not issue one license that covers every business. What you need depends on what you sell, where you work, your business structure, and whether your work is regulated. This guide shows you how to check each level without mixing up business registration, tax accounts, professional licenses, and local permits.
Bottom line
Start with your business location and activity. Form or register the business with the State Department of Assessments and Taxation when required. Then check Maryland tax accounts, the Clerk of the Circuit Court for state business licenses, any professional or industry license, and county or city zoning and permits. A Maryland LLC does not replace these approvals. Not every business needs every item.
Quick start: what to do first
- Write down exactly what the business will do, sell, make, serve, or repair.
- Choose the address where you will work, store goods, meet customers, or receive mail.
- Check whether you are a sole proprietor, partnership, LLC, corporation, or nonprofit.
- Search and register the business or trade name when needed.
- Use Maryland’s license tools to check state permits and professional licenses.
- Ask the Clerk of the Circuit Court whether your activity needs a trader’s license or another state business license.
- Register tax accounts through Maryland Tax Connect when your activity creates a tax duty.
- Check county, city, and town zoning before signing a lease or opening at home.
- Keep copies of approvals, renewal dates, account numbers, and receipts.

How Maryland’s business license system works
Maryland uses several offices. The right office depends on the task. A filing with one office does not automatically complete the others.
| Government level | What it may handle | Where to start |
|---|---|---|
| Federal | Employer Identification Number, federal industry permits, payroll and income tax duties | IRS EIN application and the federal agency that regulates your industry |
| Maryland state | Entity filings, trade names, tax accounts, trader’s licenses, professional licenses, food processing, child care, alcohol, tobacco, and cannabis rules | Maryland Business Express and Maryland OneStop |
| County | Zoning, use and occupancy, building permits, health permits, county business licenses, fire review, and signs | Your county planning, permitting, finance, health, or licensing office |
| City or town | Local zoning, home occupation approval, local permits, signs, inspections, and special business rules | The city or town where the business site is located |
Do not treat these as the same document
An LLC filing creates a legal business entity. A trade name lets you use a name. A sales and use tax license covers certain tax duties. A trader’s license covers many businesses that sell goods. A professional license allows a person or firm to perform regulated work. Zoning approval covers whether the activity may operate at a location. See the plain-English comparison of a business license, LLC, DBA, and seller’s permit.
Step 1: register the business and its name
Many Maryland businesses begin with the State Department of Assessments and Taxation, often called SDAT. You can use Maryland Business Express to register a business. Sole proprietors who use only their legal names may not need an entity filing, but they can still need licenses, tax accounts, and local approval.
Choose the legal structure
An LLC, corporation, limited partnership, or similar entity generally must file formation or registration papers before doing business in Maryland. Most entities also need a Maryland resident agent with a physical Maryland address. The business itself cannot act as its own resident agent.
Form the entity before applying for an EIN if you are creating an LLC, partnership, corporation, or tax-exempt organization. The IRS issues EINs for free. Avoid websites that charge only to pass your information to the IRS.
Remember that an entity filing does not provide operating permission. Our guide to whether LLCs still need business licenses explains why these steps are separate.
Register a trade name when needed
A trade name is the public name used instead of the owner’s legal name or the entity’s exact legal name. Maryland also uses the term “trade name” for what many people call a DBA. Search the name first and review the Maryland business-name rules. Registering a trade name does not give broad trademark rights and does not prove that zoning or licensing is complete.
Know the current state filing costs
The current SDAT fee schedule lists a $100 filing fee for Maryland LLC Articles of Organization and $25 for a trade-name filing. It also lists expedited options and a 3% service fee for online Maryland Business Express payments. Fees and processing times can change, so check the schedule immediately before filing.
File the annual report
Maryland domestic and foreign business entities generally file an annual report with SDAT. For 2026, the filing deadline was April 15. A timely extension request could move the deadline to June 15. Most entities pay a $300 annual report fee, but some entities have a different fee, an exemption, or a possible MarylandSaves waiver. Use the current SDAT forms and annual-report page for the correct year.
Good standing matters
Missing annual reports, taxes, or required filings can cause loss of good standing or forfeiture. That can block a license, renewal, contract, bank request, or other business action. Fix entity and tax problems before the renewal deadline.
Step 2: check for a trader’s license or another state business license
Maryland does not require one general state license for every business. It does require specific state business licenses for certain activities. The Comptroller’s State License Bureau oversees these license categories, while the Clerk of the Circuit Court in the county or Baltimore City usually issues the license.
Who commonly needs a trader’s license?
A trader’s license generally applies when a business sells goods or merchandise at retail or wholesale. The rule can cover storefronts, warehouses, online sellers, home-based sellers, and other sellers with commercial stock. The fee is based on the value of commercial inventory reported on the business personal property return. Certain growers, makers, manufacturers, qualifying nonprofits, and limited personal-property sales may be exempt.
Use the Comptroller’s business license FAQ to check the activity. Then contact the Clerk of the Circuit Court where the business is located. You can also search issued licenses through the Maryland Judiciary business license search.
Other state business license categories
The state list includes licenses for activities such as restaurants, chain stores, commercial garages, construction firms, out-of-state contractors, hawkers and peddlers, junk dealers, laundries, storage warehouses, vending machines, cigarette and other tobacco sales, electronic smoking devices, vape shops, and certain amusement devices. The exact license name matters. Review the Comptroller’s current business license page instead of asking only for a “general business license.”
| Your activity | Possible state item | Important distinction |
|---|---|---|
| Sell goods from a store, home, warehouse, or website | Trader’s license | Separate from the Maryland sales and use tax license |
| Sell temporarily at shows or events | Trader’s show license, transient vendor license, temporary sales tax license, or local event approval | These have different tests and time limits |
| Operate a restaurant | State business license plus local food and zoning approvals | The clerk’s license does not replace health approval |
| Perform construction work | Construction firm, out-of-state contractor, professional, or home-improvement licensing may apply | The correct item depends on the work and customer |
| Sell tobacco or vaping products | Product-specific state license and possible local approval | Age, product, and tax rules also apply |
License year and renewal
Maryland state business licenses issued through the clerks generally run from May 1 through April 30. Renewal is due by May 1. Do not wait until the last day if your entity is not in good standing or your personal property return is missing. The clerk may be unable to issue the license until those problems are fixed.
For help with license categories, the State License Bureau lists 410-260-6240 and 1-866-239-9359. Confirm office hours and contact details on the official page before calling.
Step 3: register Maryland tax accounts
Tax registration is not the same as a business license. Use Maryland Tax Connect to complete the Combined Registration Application for the accounts your business needs.
Sales and use tax
You may need a Maryland sales and use tax license if you sell taxable goods or taxable services. Review the Comptroller’s sales and use tax guidance before collecting tax. Do not collect sales tax until you know the sale is taxable and your account is set up correctly.
A sales and use tax license does not automatically make every purchase tax-free. A business buying items for resale generally gives the supplier a valid resale certificate for qualifying purchases. Read our guide to a seller’s permit versus a business license for the basic difference.
Temporary and mobile selling
A one-time event may require a temporary sales and use tax license, which the Comptroller says can be valid for 30 days. A transient vendor license is a separate free license that is generally valid for 90 days and requires a Maryland sales and use tax license. A local trader’s license or event permit may also apply. Check the Comptroller’s transient vendor guidance before traveling to a show, fair, market, or temporary site.
Employees and payroll
Before paying employees, register the correct withholding and unemployment accounts. New employers can use Maryland Labor’s BEACON new-employer instructions. Maryland employers must also report new and rehired workers within 20 days through the Maryland New Hire Registry. Check workers’ compensation duties before the first employee starts.
Tax help
The Comptroller’s Taxpayer Services line lists 410-260-7980 for Central Maryland and 1-800-638-2937 from elsewhere in Maryland. Have your entity name, federal EIN, address, activity, and expected start date ready.
Step 4: check professional and industry licenses
A trader’s license or local business license does not let you perform regulated work. The person, firm, location, equipment, or product may need a separate approval.
Professional and occupational work
Maryland Labor licenses many professions and trades, including home improvement, electrical, plumbing, HVACR, real estate, cosmetology, and other fields. Search the Division of Occupational and Professional Licensing before advertising or accepting work.
Food businesses
Food processing, manufacturing, dairy, retail food, restaurants, catering, and mobile food can follow different rules. The Maryland Department of Health’s food license and permit page directs retail operators to the local health department.
Child care
Family child care homes and child care centers must follow Office of Child Care rules. Start with the state’s child care licensing page before caring for children for pay.
Alcohol and tobacco
Alcohol and tobacco rules can involve state and local licenses. Use the Alcohol, Tobacco, and Cannabis Commission’s license and permit instructions. Many submissions now use Maryland OneStop.
Cannabis
Cannabis business licenses are specialized and may be offered only through set application rounds. Check the Maryland Cannabis Administration’s business licensing page. Do not assume a normal retail application is open.
Wait for approval before working
Some regulated jobs cannot be advertised, contracted, sold, or performed before the license is active. A pending application is not the same as approval. Check the regulator’s public license lookup when one is available.
Step 5: check county, city, and town rules
Local approval is often the part people miss. Maryland counties and municipalities can control land use, signs, building work, occupancy, food service, fire safety, short-term rentals, special events, and certain business types. The rules depend on the exact address, not only the mailing city.
Ask zoning before signing a lease
Give the zoning office a clear description of the activity. Include customer visits, employees, hours, deliveries, outdoor storage, signs, noise, food, chemicals, vehicles, and equipment. Ask whether the use is allowed and whether you need a use permit, certificate of occupancy, change-of-use review, home occupation approval, or hearing.
Home-based businesses
A home business can still need zoning approval, a trader’s license, tax registration, professional licensing, or a landlord or homeowners association review. Start with our guide to running a business from home and the explanation of a home occupation permit. Do not assume “online only” means local rules do not apply.
| Location example | Official starting point | What to check |
|---|---|---|
| Baltimore City | Baltimore City business permits and licensing | Property use, occupancy, construction, signs, health, fire, and city-regulated activities. Also see the detailed Baltimore business license guide. |
| Baltimore County | Baltimore County zoning | Whether the activity is allowed at the site and whether a zoning use permit or other approval is required |
| Montgomery County | Montgomery County Department of Permitting Services | Use and occupancy, building, signs, fire systems, and related permits; separate county business license rules may apply |
| Prince George’s County | Prince George’s County business licenses | County-regulated activities and whether a separate state license is still needed |
| Any incorporated city or town | Municipal clerk, planning, zoning, permitting, or finance office | Local rules that are separate from county and state requirements |
What to ask the local office
Phone script
“I plan to operate a business at [address]. I will [describe the work], have [number] employees, receive [yes/no] customer visits, and store [goods/equipment]. Is this use allowed? Do I need zoning approval, a home occupation permit, use and occupancy approval, a local business license, health or fire review, or a sign permit?”
Ask the staff member to email the page, application, or written rule. Save the reply with your business records.
What you may need based on how you operate
Your operating model changes the checklist. Use this table as a set of questions, not as a promise that every item applies.
| Operating model | Items to check | Common blind spot |
|---|---|---|
| Home-based service business | Entity or trade name, local zoning or home occupation rules, professional license if regulated, tax and employer accounts | Customer visits, work vehicles, signs, storage, or employees can change zoning treatment |
| Online seller | Trader’s license, sales and use tax account, entity or trade name, home zoning, inventory reporting, marketplace records | A marketplace may collect some sales tax but does not replace every seller duty. See whether online businesses need a business license. |
| Storefront or office | Zoning, use and occupancy, building or sign permits, state business license, tax accounts, industry approvals | The former tenant’s approvals may not cover your use |
| Mobile or event seller | Sales tax, transient vendor or temporary license, trader’s license, event approval, food or health permit, each location’s rules | One county’s approval may not work in another county or city |
| Food business | Local health approval, possible state food processing license, zoning, fire review, trader’s or restaurant license, sales tax | A cottage-food rule, catering permit, mobile unit permit, and restaurant permit are not interchangeable |
| Employer | Withholding, unemployment, new-hire reporting, workers’ compensation, workplace and professional rules | Hiring the first worker can create duties before the first paycheck |
Maryland costs and renewal dates to plan for
There is no single price for a Maryland business license. Your total depends on the entity, inventory, business type, location, and permits. The figures below are verified starting points, not a full quote.
| Item | Current amount or timing | What to verify |
|---|---|---|
| Maryland LLC Articles of Organization | $100 base filing fee | Expedited and online service fees |
| Maryland trade name | $25 base filing fee | Expedited and online service fees |
| Annual report | Usually due April 15; most entities pay $300 | Current-year form, entity-specific fee, exemption, waiver, or extension |
| Trader’s license | Fee depends on commercial inventory | Inventory reported to SDAT and any exemption |
| Other state business licenses | Varies by license type | Clerk fee, state fee, license period, and supporting documents |
| Clerk-issued business license year | May 1 through April 30; renew by May 1 | Good standing, personal property return, taxes, and local requirements |
| Local permits | Varies by county, city, project, and use | Application, inspection, plan review, hearing, and renewal fees |
| Federal EIN | Free from the IRS | Apply through the official IRS site |
Do not budget only for the license fee. A site can also require plans, inspections, construction, fire systems, grease control, accessibility work, signs, or professional help.
Common mistakes to avoid
- Forming an LLC and stopping there. The LLC is not an operating license.
- Calling every approval a business license. Ask for the exact permit, account, or certificate name.
- Signing a lease before zoning review. A legal address does not mean your use is allowed.
- Confusing a trader’s license with a sales tax license. A seller may need both.
- Ignoring inventory reporting. Commercial inventory can affect trader’s license issuance and cost.
- Assuming an online or home business has no local rules. The operating address still matters.
- Using approval from one county in another. Local permits usually do not transfer across jurisdictions.
- Missing the April or May renewal cycle. Annual reports and clerk-issued licenses have different deadlines.
- Starting regulated work while an application is pending. Wait until the license is active.
- Paying a private filing site without checking the official portal. Government filings may be cheaper or free when filed directly.

Careful review note
This guide is general information, not legal, tax, or accounting advice. Maryland agencies, courts, counties, cities, and towns can change forms, fees, names, deadlines, and rules. Your exact duties depend on the business activity, legal structure, address, products, services, employees, and regulated work. Confirm current requirements with the official office before you spend money, sign a lease, sell products, hire workers, or begin regulated work.
