Your complete reference guide to the most important compliance requirements for Maryland businesses — employment law, licensing, data privacy, contracts, and annual filings.
This guide is for informational purposes only and does not constitute legal advice. Laws change frequently. Always consult a licensed Maryland attorney for advice specific to your business situation.
Maintaining your business entity in good standing with the state of Maryland requires consistent annual attention. Many business owners form their LLC and forget about state compliance entirely — until they receive a forfeiture notice.
Every Maryland LLC and corporation must file an Annual Report with the State Department of Assessments and Taxation (SDAT) by April 15 each year. The fee is $300 for LLCs. Missing this deadline results in your entity being placed in "not in good standing" status, and continued non-filing results in forfeiture — meaning your business no longer legally exists in Maryland.
If your entity is forfeited, you must file all missing annual reports, pay all outstanding fees and penalties, and file for reinstatement. This process can take weeks and costs significantly more than simply filing on time each year.
Maryland requires every LLC and corporation to maintain a registered agent — a person or company with a physical Maryland address who can receive legal documents on behalf of the business. If you move or your agent changes, update SDAT immediately. Failure to maintain a registered agent can result in your entity losing its good standing.
| Filing | Due Date | Fee | Penalty for Missing |
|---|---|---|---|
| Annual Report (LLC) | April 15 | $300 | Not in good standing, then forfeiture |
| Annual Report (Corporation) | April 15 | $300 min | Not in good standing, then forfeiture |
| Personal Property Return | April 15 | Varies | Penalty + interest on unpaid taxes |
| Sales Tax Filing | Monthly/Quarterly | N/A | Penalty + interest |
| Employer Withholding | Monthly/Quarterly | N/A | Penalty + interest |
Maryland has some of the most employee-protective employment laws in the country. Employers in Maryland must comply with both federal law and Maryland's often more stringent state requirements.
Maryland law requires employers to display specific posters in the workplace. Failure to display required posters can result in fines. Required postings include:
Employers with 50+ employees must provide 60 days advance notice before mass layoffs affecting 25+ employees or plant closings. Maryland's WARN Act applies to businesses that have been in operation for at least one year.
Maryland significantly restricted non-compete agreements effective October 2019. Non-competes are unenforceable for employees earning $15/hr or less ($31,200/year). For employees above this threshold, courts apply a reasonableness test looking at duration, geographic scope, and business necessity. Non-solicitation agreements are generally treated more favorably than non-competes.
As of October 2024, Maryland employers with 15+ employees must include wage range and a general description of benefits in all public job listings. This applies to external job postings. Failure to comply can result in civil penalties.
Maryland's wage and hour laws are complex and carry significant penalties for non-compliance. These are among the most frequent sources of employment litigation for small businesses.
Maryland's statewide minimum wage is currently $15.00/hour for most employers. Montgomery County and Prince George's County may have higher local minimums — always check county requirements for businesses operating in those jurisdictions.
Non-exempt employees must be paid 1.5x their regular rate for hours worked over 40 in a workweek. Maryland follows federal FLSA standards for overtime exemptions. Common misclassification errors: paying salaried employees without meeting the salary basis test, misclassifying managers as exempt when their primary duty isn't management.
This law governs when and how employees must be paid. Key requirements:
Employers with 15+ employees must provide paid sick and safe leave. Employers with fewer than 15 employees must provide unpaid sick leave. Employees accrue 1 hour of leave for every 30 hours worked, up to 40 hours per year. Leave can be used for the employee's own illness, a family member's illness, or domestic violence situations.
Wage theft violations carry some of the harshest penalties in Maryland employment law. An employee who successfully proves their employer withheld wages can recover three times the amount owed plus attorney's fees. Consult an employment attorney before making any deductions from employee pay.
Maryland requires virtually all employers with one or more employees to carry workers' compensation insurance. There is no minimum number of hours or type of employment — even part-time workers trigger this requirement. Failure to carry workers' comp while employing workers is a misdemeanor in Maryland and can result in fines up to $10,000 plus personal liability for any workplace injuries.
Maryland operates its own state-level occupational safety and health program (MOSH) under federal OSHA approval. MOSH conducts workplace inspections, investigates complaints, and enforces safety standards. Penalties can reach $15,625 per violation for serious violations and $156,259 for willful or repeated violations.
The Maryland MOSH Consultation Program offers free, confidential safety and health consultations for small businesses. Consultants help identify workplace hazards and recommend corrections — with no citations or penalties issued during the consultation visit. This is one of the most underutilized free services available to Maryland employers.
Many small business disputes stem from handshake agreements and informal understandings that later become contentious. Getting your key contracts in writing is one of the highest-ROI legal investments you can make.
Maryland follows general common law contract principles. Key points for enforceability: contracts don't need to be notarized to be enforceable, electronic signatures are valid under Maryland law (UETA), oral contracts can be enforceable but are difficult to prove, and some contracts (real estate, agreements lasting more than one year) must be in writing to be enforceable under the Statute of Frauds.
Maryland has specific statutory requirements for home improvement contracts. Contractors must be licensed, contracts over $500 must be in writing with specific required disclosures, and consumers have a right to cancel within 3 business days. Failure to comply can result in the contract being voided and the contractor being unable to collect payment.
Data privacy law is one of the fastest-changing areas of business compliance. Maryland has enacted its own consumer data privacy law that applies to many small businesses.
Effective October 2025, MODPA applies to businesses that process personal data of 35,000+ Maryland consumers, or 10,000+ consumers and derive 20%+ of revenue from selling data. Requirements include: privacy notice to consumers, right to access and delete personal data, opt-out rights for targeted advertising and data sales, and data security requirements.
If you accept credit card payments, you must comply with PCI DSS standards regardless of your business size. Key requirements: never store cardholder data you don't need, use a reputable payment processor, and maintain your network security. Non-compliance can result in fines from card networks and loss of the ability to accept card payments.
If your business experiences a data breach affecting Maryland residents' personal information, you must notify affected individuals "as soon as reasonably possible." The Maryland Attorney General must also be notified if 1,000+ individuals are affected. Failure to notify can result in significant civil penalties.
Beyond general business registration, many Maryland industries require specific professional licenses. Operating without required licenses is a criminal offense in most cases and can result in voided contracts, fines, and inability to collect payment for services rendered.
