Maryland has the most complex state tax structure in the US - a two-tier system with BOTH state income tax (2-5.75%, 10 brackets) AND mandatory county income tax (2.25-3.3%, varies by county). You cannot avoid county tax - all MD residents pay it. At $100K income: $3,933 state + $2,433 avg county = $6,366 combined (6.37% effective) on $83,900 taxable income.
How Maryland's unique dual tax works: Unlike most states (where local income tax is rare), Maryland requires ALL 23 counties + Baltimore City to levy local income tax. You file one state return but pay two separate taxes: state (2-5.75%) and county (2.25-3.3%). Montgomery County (DC suburbs) and Baltimore City have the highest county rates (3.3%). Somerset County (Eastern Shore) has the lowest (2.25%). At $100K: Montgomery resident pays $3,933 state + $2,769 county ($83,900 × 3.3%) = $6,702 total (6.70%). Somerset resident pays $3,933 state + $1,888 county ($83,900 × 2.25%) = $5,821 total (5.82%). Same state tax, different county tax.
Regional comparison: Virginia (2-5.75% state, NO county tax), Pennsylvania (3.07% state + 1-3.9% local in some cities), DC (4-10.75%), Delaware (2.2-6.6%). At $100K: MD $6,366 vs VA $4,064, PA ~$2,576 (Pittsburgh ~$3,200 with local), DC ~$6,950. Maryland's combined state+county is higher than VA but comparable to DC.
Note: These are marginal rates — you only pay the higher rate on income within each bracket.
Here's what Maryland residents actually pay at different income levels (2026, single filer, standard deduction):
| Annual Income | Federal Tax | State Tax | Total Tax | Take-Home Pay | Effective Rate |
|---|---|---|---|---|---|
| $50,000 | $3,820 | $2,541 | $6,361 | $43,639 | 12.7% |
| $75,000 | $7,670 | $4,453 | $12,123 | $62,877 | 16.2% |
| $100,000 | $13,170 | $6,366 | $19,536 | $80,464 | 19.5% |
| $150,000 | $24,734 | $10,298 | $35,032 | $114,968 | 23.4% |
| $250,000 | $51,304 | $18,658 | $69,962 | $180,038 | 28.0% |
Note: Includes federal and state income tax only. Does not include FICA (Social Security/Medicare), which adds 7.65% for employees.
Key takeaway: At $100K, Maryland takes $6,366 in state tax alone.

Migration Trends: Maryland experienced modest net immigration of 1,230 residents (2021-2022). Top origin: Virginia (18,670 from VA - DC area job churn), DC (7,890 from DC - seeking lower housing costs than DC proper), Pennsylvania (6,120 from PA - Baltimore jobs). Outflow: Florida (14,560 to FL - 0% tax, retirees), Virginia (15,340 to VA - lower VA tax 5.75% vs MD 7.65% at $100K), Texas (8,230 to TX - 0% tax).
Why people move to Maryland: DC area federal jobs (NIH, NSA, Social Security Administration), biotech (NIH corridor), defense contractors (Lockheed, Northrop Grumman), Johns Hopkins University/Hospital, Chesapeake Bay access, excellent schools (Montgomery County ranks top-20 nationally). Why people leave: High taxes (7.65-9.05% combined state+county), high cost (Montgomery County median $680K home), better tax deals in VA (5.75% max, no local tax = save $2,302/year at $100K).
Tax considerations: County tax varies 2.25-3.3% (Montgomery/Baltimore City 3.3% highest). Property tax: 1.09% avg (Montgomery 0.93%, Baltimore City 2.25%). DC/VA/MD commuter triangle: Live where you want, but MD residents pay highest tax. Social Security: fully exempt up to $50K retirement income. Nonresidents working in MD pay 2.25% county tax (flat rate for all nonresidents). Remote worker note: If MD resident working for out-of-state employer, pay full MD tax on all income.
| State | Tax Rate | Tax on $100K Income | Difference from Maryland |
|---|---|---|---|
| Maryland | 2-5.75% + 2.25-3.3% county | $6,366 | Baseline |
| Virginia | 2-5.75% | $4,064 | −$2,302 (save) |
| Pennsylvania | 3.07% + local varies | $2,576 | −$3,790 (save) |
| Delaware | 2.2-6.6% | $5,550 | −$816 (save) |
| DC | 4-10.75% | $6,950 | +$584 (more tax) |
Key insight: Maryland's combined state+county tax (6.37% effective at $100K) is higher than VA and PA but comparable to DC. At $100K: VA saves $2,302/year, PA saves ~$3,296/year. At $150K: VA saves $3,359/year. The Virginia arbitrage is significant for DC-area workers: live in NoVA (Arlington/Fairfax), work in MD/DC, pay only VA 5.75% max with NO county tax.
The DC/MD/VA triangle - where should you live? DC area jobs are spread across all 3 jurisdictions. At $150K: MD resident pays $10,298 total state+county tax (6.87% effective). VA resident pays $6,939 (4.63%). DC resident pays ~$11,675 (7.78%). Winner: Virginia saves $3,359/year vs MD, ~$4,736/year vs DC. Many choose VA for lower taxes despite slightly higher home prices (Fairfax $650K vs Montgomery MD $680K — tax savings outweigh the mortgage difference).
Bottom line: Maryland's state+county tax structure makes it less competitive than VA in the DMV region. If you work in DC area, living in Virginia saves $2,000-3,500/year at typical professional salaries ($100-150K). Only stay in MD for: Montgomery County schools (top-20 nationally), Johns Hopkins affiliation, Chesapeake Bay waterfront, or convenience for MD-specific sites (NIH Bethesda, NSA Fort Meade, Aberdeen Proving Ground).
All Maryland residents must pay county income tax (2.25-3.3%) in addition to state tax (2-5.75%). You file one state return but pay two taxes. County tax is based on where you live on Dec 31, not where you work. Highest county rates: Montgomery County 3.3% (DC suburbs), Baltimore City 3.3%, Howard County 3.2%. Lowest: Somerset County 2.25% (Eastern Shore). At $100K: everyone pays $3,933 state tax (on $83,900 taxable). Montgomery resident adds $2,769 county ($83,900 × 3.3%) = $6,702 total (6.70%). Calvert County (2.5%) resident adds $2,098 county = $6,031 total (6.03%). Nonresidents working in MD pay flat 2.25% county rate.
Virginia saves significant tax. At $100K: VA pays $4,064 state tax (no county tax) vs MD $6,366 state+county = save $2,302/year in VA. At $150K: VA pays $6,939 vs MD $10,298 = save $3,359/year. Housing: Northern VA (Arlington/Fairfax) median $650K vs Montgomery MD $680K - VA is slightly cheaper + lower taxes. Schools: Montgomery County MD ranks top-20 nationally, Fairfax County VA ranks top-10 - both excellent. Commute: Similar - Arlington to DC 20 min, Bethesda MD to DC 25 min. Bottom line: Virginia is better financially (save $2,300-3,400/year at typical salaries). Only choose MD for specific ties (Johns Hopkins, NIH Bethesda campus jobs, Chesapeake Bay waterfront).
Partially. Social Security: Fully exempt if total MD adjusted gross income is under $50,000 (all filing statuses). Above $50,000, SS is fully taxable at MD state+county rates. Pension/401k/IRA: Fully taxable at 2-5.75% state + 2.25-3.3% county. BUT: Taxpayers 65+ can deduct up to $34,300 of pension/retirement income (2026 amount, indexed to inflation). At typical retiree income ($35K SS + $35K pension = $70K): $35K SS fully taxed (over $50K threshold), $34.3K pension deducted = only $35.7K taxable, pay ~$2,500 MD tax. This is moderate - better than CA ($5,762 at $70K), worse than VA ($2,625), much worse than FL/TX (0%). MD also has no estate or inheritance tax.
State tax (2-5.75%, 10 brackets) is the same for all MD residents based on income level. County tax (2.25-3.3%) varies by which county you live in on December 31. Example at $100K: Everyone pays $4,750 state tax. Montgomery County resident adds $3,300 county tax (3.3% rate) = $8,050 total. Calvert County resident adds $2,500 county tax (2.5% rate) = $7,250 total. Same state tax, different county tax based on residence. You file one Form 502 (MD resident return) but it calculates both taxes. Nonresidents working in MD pay state tax + flat 2.25% county tax (not their home state's rates).
Maryland's total burden is higher. At $100K with $450K home: MD pays $6,366 income (state+county) + $4,905 property (1.09% avg) + $3,000 sales (6% avg on $50K) = $14,271 total (14.3%). VA pays $4,064 income + $4,050 property (0.90% avg) + $2,725 sales (5.45% avg) = $10,839 total (10.8%). MD pays $3,432 more/year. Over 10 years: MD pays ~$34,320 more than VA. But: Montgomery County MD schools rank higher than most VA counties (except Fairfax/Loudoun which are comparable). Trade-off: Pay $3,400/year more for MD schools/services, or save that in VA with similar school quality in Fairfax/Loudoun.

How we calculate: Maryland uses 10 state brackets (2-5.75%) PLUS mandatory county tax (2.25-3.3%). We calculate state tax using 10-bracket progressive structure, add average county rate (2.9% used in examples, varies 2.25-3.3% by county), and add federal tax. Data sources: Maryland Comptroller (2026 rates/brackets), U.S. Census Bureau (migration). Verification: MD's 10-bracket structure and county rates verified against Maryland Tax Code and Comptroller 2026 guidance. County rates: Montgomery/Baltimore City 3.3%, Howard 3.2%, Somerset 2.25% verified against official county tax tables. Limitations: Assumes Montgomery County (3.3%) or average county rate (2.9%). Does not include: county-specific rates (varies 2.25-3.3%), MD-specific deductions ($34,300 pension deduction age 65+, $50K Social Security exemption threshold), property tax variations (0.93% Montgomery, 2.25% Baltimore City, 0.6-1.5% rural).
