Maryland combines a progressive state income tax (2% to 5.75% in 2025, with two new brackets of 6.25% on income over $500K and 6.5% on income over $1M starting in tax year 2025) with a mandatory local income tax collected at rates set by each county and Baltimore City. Local rates range from 2.25% (a handful of counties) up to 3.20% (Howard, Montgomery, Prince George's, Queen Anne's, Baltimore City, and others). A Howard County employee in the 4.75% state bracket faces a 7.95% combined marginal rate; a high earner in Montgomery County can exceed 9.7% combined. Matchbook models Section 125 and 132(f) savings by county of residence, not a statewide average, because the pre-tax stack is county-dependent.
