FAQ

Frequently Asked Questions

How does Maryland's county income tax work and can you avoid it?

Maryland's county income tax is levied by all 23 counties and Baltimore City. It is mandatory — every Maryland resident pays it. The rate varies from 2.25% (Carroll, Worcester, St. Mary's counties) to 3.2% (Montgomery, Prince George's, and others). It is collected automatically on the Maryland state income tax return. There is no way to live in Maryland and avoid the county tax. An Arizonan earning $100k pays $2,500 total; a Montgomery County Marylander earning $100k pays approximately $8,440 — a $5,940 difference.

Is Arizona growing enough to replace Maryland's DC corridor job market?

Arizona cannot fully replace the DC federal job market, but it's growing rapidly. TSMC's $40B+ fab investment in Phoenix, Intel's semiconductor manufacturing, and State Farm's national headquarters create a very different but substantial job ecosystem. Phoenix is now a top-10 US metro for employment growth. For federal workers and defense contractors, Maryland's proximity to NSA, Pentagon, DIA, and federal IT hubs remains unique. For private sector, tech, finance, and manufacturing: Arizona's lower taxes and growing economy make it a genuine alternative.

What is the total tax difference for a Maryland vs Arizona homeowner?

For a $150k earner owning a $600k home: Maryland income tax ~$12,990 + property tax ~$6,540 = $19,530/year. Arizona income tax $3,750 + property tax $3,720 = $7,470/year. Annual savings in Arizona: $12,060. Over 10 years: $120,600. Even accounting for Arizona's higher sales tax (~$1,500/year more on $80k spending), Arizona homeowners at this level save ~$10,560/year. This is why Phoenix and Scottsdale have seen significant inbound migration from Maryland and Virginia.

Is Maryland considering removing or reducing the county income tax?

As of 2026, there are no significant legislative efforts to eliminate Maryland's county income tax. The county tax is authorized by state law but set locally — it would require county government action to reduce, and counties rely on it for budgets. Maryland has periodically discussed income tax reform at the state level, but the county tax layer has remained stable for decades. By contrast, Arizona's 2.5% flat rate is now constitutionally established through the legislative flat-tax implementation, providing greater certainty.

Phoenix vs Baltimore: which metro offers better value in 2026?

Phoenix wins on: taxes ($5,940/year income tax savings on $100k), property tax (0.62% vs 1.09%), housing value per square foot, new construction quality, sunshine, and rapid job growth. Baltimore wins on: Chesapeake Bay waterfront lifestyle, East Coast cultural access, Johns Hopkins biotech cluster, strong school districts in surrounding counties, and DC proximity. For most families evaluating purely on financial grounds, Phoenix's advantage is substantial and compounds each year. Baltimore's advantages are lifestyle and career-specific.
