Maryland's Unique County Tax System
Maryland is one of only a handful of states that require all counties to levy a local income tax collected through the state return. This "piggyback" tax ranges from 2.25% (Worcester County) to 3.20% (Baltimore City, Montgomery, Prince George's, Howard, and Frederick). Because all Maryland residents pay this tax โ not just city residents โ the effective state tax burden is significantly higher than the state brackets alone suggest.
