FAQ

Frequently Asked Questions

What is Maryland's county income tax and how does it work?

Maryland is unique in requiring all residents to pay both a state income tax AND a county (or city) income tax. The county rate varies: Montgomery County 3.2%, Prince George's County 3.2%, Howard County 3.2%, Baltimore County 2.83%, Anne Arundel 2.81%, Frederick County 2.96%. Baltimore City charges 3.2%. These county taxes are not optional — Maryland residents must pay both. On $100,000 income in Montgomery County: state tax ~$5,240 + county tax $3,200 = $8,440 combined vs Washington State's $0.

How does Maryland compare to neighboring Virginia for income taxes?

Both Maryland and Virginia have significant income taxes vs Washington State's zero, but Maryland's combined burden is higher. Virginia: 5.75% flat (on income above $17k) = ~$4,720 on $100k. Maryland: state 6.5% progressive + county 2.25-3.2% = ~$8,440 on $100k in Montgomery County. Maryland's mandatory county tax is the key differentiator. Washington State beats both at $0, and saves $8,440 vs Maryland and $4,720 vs Virginia per $100k earned.

Why is Maryland's median household income the highest in the US?

Maryland's extraordinary median household income (~$98,000+, highest in US) is driven by: (1) Dense federal government employment — NSA, NIH, FDA, DoD are all based in Maryland suburbs; (2) Defense contractor cluster — Lockheed Martin, Northrop Grumman, Boeing (defense division) all have major MD presences; (3) Proximity to DC driving lobbying, law, and policy salaries; (4) Education sector — Johns Hopkins, University of Maryland. Despite the high incomes, residents pay ~8.5-9.7% in combined state+county income taxes.

Is Maryland a good state for retirees?

Maryland offers partial retirement income exclusions (Social Security exempt; pension/IRA exclusions up to $36,200 for those 65+). But the mandatory county income tax still applies to taxable retirement income, making Maryland moderately expensive for retirees with significant 401k withdrawals. Washington State exempts all retirement income (no state income tax). For retirees: WA wins clearly if income is above $50,000. Maryland wins if proximity to family, DC culture, or federal pension/healthcare matters most.
