Maryland Employer Requirements
Hiring one employee in Maryland triggers four separate registration and compliance steps at once, not one form to fill out and forget. Miss any piece and the fallout ranges from processing delays to real penalties.
One rule trips up more employers than any other on this list: local income tax withholding runs off the employee's county of residence, not the employer's location or the work site. Below is the full sequence, in the order a first-time employer should tackle it.

Key Takeaways
• Withholding tax registration happens through Maryland Tax Connect, the Comptroller's online portal.
• Local income tax withholding runs off the employee's county of residence, not the business address.
• New unemployment insurance accounts pay a 2.6% rate on the first $8,500 of each employee's wages for 2026.
• New hires must be reported to the state directory within 20 days of the hire date.
• Maryland requires workers' compensation coverage for virtually every employer with at least one employee.
Step 1: Register for Maryland Withholding Tax
Register with the Comptroller of Maryland through Maryland Tax Connect before your first payroll run. Withholding covers Maryland state income tax on employee wages, plus the local piggyback tax covered below. Registration requires an EIN, so complete the EIN step first if you have not already.
Step 2: Understand the County Piggyback Income Tax
Maryland layers a local income tax on top of the state rate, and every county plus Baltimore City sets a different rate, generally between roughly 2.25% and 3.2%, with a couple of counties recently pushing to a 3.3% maximum allowed under state law. The applicable rate depends on the employee's county of residence, not where your business sits and not where the work happens. A Baltimore City business with an employee living in Howard County withholds at the Howard County rate for the employee. Confirm the current county rate table on the Comptroller's site before running payroll, since individual county rates shift periodically.
Step 3: Register for Unemployment Insurance
Register with the Maryland Department of Labor's Division of Unemployment Insurance. New employers pay a standard rate, set at 2.6% for 2026, on the first $8,500 of each employee's wages for the year. Rates for established employers shift based on claims history, ranging more broadly across the state's rate table. Confirm the current new-employer rate and wage base before budgeting payroll costs, since the rate and wage base are set or adjusted periodically.
Step 4: Report New Hires Within 20 Days
Report every new hire and rehire to the Maryland State Directory of New Hires within 20 days of the hire date. The report needs the employee's name, address, and Social Security Number, plus the employer's name, address, and EIN. The state uses this data mainly for child support enforcement, and shares it with the unemployment insurance division to catch benefit fraud. Confirm current submission methods and any penalty figures on the Department of Human Services site.
Step 5: Get Workers' Compensation Coverage
Maryland requires workers' compensation coverage for virtually every employer with at least one employee, full-time or part-time. Coverage runs through a private insurer, or through Chesapeake Employers Insurance Company, Maryland's state-chartered insurer of last resort for businesses unable to secure private coverage. A narrow exemption applies to some small agricultural employers. Operating without required coverage carries steep penalties, so confirm your specific obligation with the Maryland Workers' Compensation Commission before your first hire starts work.
Step 6: Post Required Workplace Notices
Maryland and federal law require posting specific workplace notices where employees can see them, covering topics such as minimum wage, unemployment insurance, workers' compensation, and workplace safety. Physical posters and, increasingly, digital equivalents for remote staff satisfy the requirement in many cases. Confirm the current required poster list through the Maryland Department of Labor before your first employee starts.
Step 7: Understand Maryland Wage and Hour Basics
Maryland sets a state minimum wage, which can run above the federal minimum, plus overtime rules generally following federal standards at time and a half after 40 hours in a week. Pay frequency rules require regular, predictable paydays. Confirm the current minimum wage figure directly with the Maryland Department of Labor, since it can change from year to year.
Common Mistakes
• Withholding local tax based on the business address instead of the employee's county of residence.
• Assuming workers' compensation is optional for a small number of employees.
• Missing the 20-day new hire reporting window.
• Registering for withholding but skipping unemployment insurance registration, or the reverse.
• Failing to post required workplace notices before the first employee starts.
