Baltimore City levies the highest local income tax rate in the United States — 3.2% — on top of Maryland's progressive state rates reaching 5.75%. For a high-income Baltimore City resident, the combined state-local burden of 8.95% approaches New York City levels, yet Baltimore housing costs a fraction of comparable coastal cities. Maryland's estate tax (triggering at $5M rather than the federal $13.61M) creates significant planning needs for homeowners and business owners in the Baltimore metro area. Understanding the distinction between Baltimore City and Baltimore County — two completely separate jurisdictions with different tax rates — is essential for anyone considering relocation within the metro.
For a household earning $200,000: Baltimore City pays approximately $9,800 in Maryland state tax + $6,240 city piggyback + $8,992 property tax on a $400K home = ~$25,000/year. Baltimore County pays approximately $9,800 state + $5,519 county piggyback + $4,400 property tax = ~$19,700/year. Annual saving in suburbs: ~$5,300. For $400,000 earners, the gap exceeds $10,000/year. City housing is cheaper but the ongoing tax differential compounds significantly over time.

A Baltimore County resident commuting to Baltimore City pays Baltimore County's 2.83% rate, not the city's 3.2%. Your employer should withhold your home county rate. This is different from NYC or Pittsburgh which tax non-residents on work income.
Maryland's $5M estate tax threshold is far below the federal $13.61M exemption. A Maryland couple with a $10M estate owes no federal estate tax but owes significant Maryland estate tax without proper trust planning. AB trusts, QTIP trusts, and annual gifting strategies are commonly used by Maryland estate attorneys to fully use both spouses' $5M Maryland exemptions. This is a priority planning issue for homeowners in expensive Baltimore neighbourhoods whose estates may have crossed $5M through home appreciation and retirement savings.
Maryland fully exempts Social Security if your federal AGI is under $100,000 (single) or $150,000 (married). Above those thresholds, Social Security is taxable at Maryland rates. For most middle-income retirees, Social Security is effectively state-tax-free. The thresholds are not inflation-adjusted, so more retirees enter the taxable range each year.
Maryland allows a pension exclusion of up to $37,600 for residents 65+ and $20,000 for residents 55-64. This applies to 401(k), IRA, and employer pension distributions. The exclusion reduces Maryland taxable income AND the Baltimore City piggyback base, effectively reducing local tax as well. Military pensions are fully exempt with no cap.
No. Maryland's sales tax is 6% statewide — no county or city additions are permitted. Baltimore City charges exactly 6%, same as every other Maryland jurisdiction. This is a notable advantage: unlike Chicago (10.25%) or Denver (8.81%), Baltimore's 6% rate is flat and simple statewide.
Baltimore City offers: the Homestead Tax Credit (caps annual assessment increases at 4% for owner-occupants); the Homeowners' Property Tax Credit (income-based relief for residents paying property taxes exceeding a set percentage of income — a Maryland state programme); senior citizen tax credits for residents 65+ with limited income. Applications are filed with the Maryland State Department of Assessments and Taxation.
