What Makes Maryland Payroll Complex
Maryland's payroll complexity comes from its layered tax structure. Beyond the state's 10 income tax brackets, every Maryland county and Baltimore City levies its own local income tax at rates from 2.25% to 3.20%. Employers must withhold both the state tax and the correct county tax based on each employee's residence, making Maryland one of the more complicated states for multi-location teams.
The state added two new high-income brackets in 2025 (6.25% and 6.5%), increasing the withholding burden for higher-earning employees. Maryland's SUI wage base of $8,500 is low, which is a silver lining. The county piggyback taxes, however, require employers to track employee residences carefully and apply the correct local rate.
This guide breaks down each of Maryland's employer obligations: registration requirements, 2026 tax rates and wage bases, filing deadlines, and the compliance pitfalls that catch expanding startups off guard. Whether you're hiring your first Maryland employee or managing a growing remote team, everything you need to stay compliant is here.
