Choosing a PEO in Maryland
Maryland's minimum wage is $15.00 per hour statewide as of 2026. Montgomery County — one of the most affluent counties in the country — sets its own higher rates: $17.65 per hour for large employers, $16.00 for mid-sized employers, and $15.50 for small employers. Employers with employees in Montgomery County must verify which rate applies based on their size. Maryland is not a right-to-work state, and its labor market — particularly in the Baltimore and Washington D.C. corridor — is highly competitive across government contracting, healthcare, technology, and professional services.
Maryland is launching a significant new employee benefit in 2026: the Maryland Family and Medical Leave Insurance (FAMLI) program. Employer and employee payroll contributions began January 1, 2026, though benefits do not begin until January 1, 2027. Employers must register, begin collecting premiums, and communicate the program to employees now — making this a critical compliance priority for Maryland businesses in 2026. Maryland also requires employers to provide paid sick and safe leave — up to 40 hours per year for employers with 15 or more employees, accruing at 1 hour per 30 hours worked.
Workers' compensation insurance is required for all Maryland employers with one or more employees — one of the broadest workers' comp mandates in the country. Coverage is obtained through private insurance carriers or the Chesapeake Employers' Insurance Company, Maryland's state-operated carrier. Maryland follows the federal WARN Act, requiring 60 days advance notice for layoffs affecting 50 or more employees. Maryland's Equal Pay for Equal Work Act requires pay transparency — employers must provide salary range information to applicants upon request and cannot prohibit employees from discussing wages.
Maryland's economy is anchored by federal government employment, defense contracting, healthcare, and biotechnology — particularly in the Baltimore and Montgomery County corridors. The proximity to Washington D.C. creates a labor market where federal compensation benchmarks influence private sector pay expectations significantly. A PEO with Maryland expertise can help businesses manage the new FAMLI contribution requirements, paid sick leave administration, workers' comp compliance, and pay transparency obligations. Use the form on this page to connect with qualified PEOs serving Maryland businesses.

Frequently Asked Questions
What is the minimum wage in Maryland in 2026?
Maryland's statewide minimum wage is $15.00 per hour as of 2026. Montgomery County sets higher rates: $17.65 per hour for large employers, $16.00 for mid-sized employers, and $15.50 for small employers. Employers with employees in Montgomery County must comply with the applicable local rate based on their size classification.
What is Maryland's new FAMLI program and when does it start?
Maryland's Family and Medical Leave Insurance (FAMLI) program requires employer and employee payroll contributions beginning January 1, 2026. Benefits — providing paid family and medical leave to employees — begin January 1, 2027. Employers must register with the state, begin collecting premiums through payroll, and notify employees of the upcoming benefit. A PEO can manage FAMLI contributions and administration on behalf of Maryland employers.
Is workers' compensation required in Maryland?
Yes. Maryland requires all employers with one or more employees to carry workers' compensation insurance — one of the broadest mandates in the country. Coverage can be obtained through private insurers or the state-operated Chesapeake Employers' Insurance Company. A PEO provides workers' comp as part of the co-employment arrangement, typically at competitive rates.
Does Maryland require paid sick leave?
Yes. Maryland's Healthy Working Families Act requires employers with 15 or more employees to provide up to 40 hours of paid sick and safe leave per year, accruing at 1 hour per 30 hours worked. Employers with fewer than 15 employees must provide the same amount of unpaid leave. Leave can be used for the employee's illness, a family member's illness, or reasons related to domestic violence or sexual assault.
