Maryland has an unusual two-tier income tax structure - a system with BOTH state income tax (2-6.5%, 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: $4,384 state + $2,989 county (using Montgomery County's 3.2% rate, representative of most populous counties) = $7,373 combined (7.37% effective) on $100,000 gross income ($93,400 taxable after the $3,400 standard deduction and $3,200 exemption).
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 (2-6.5%) and county (2.25-3.3%). Dorchester and Kent counties have the highest county rate (3.3%); Montgomery, Baltimore City, Prince George's, Howard, and most other populous counties sit at 3.2%. Worcester County (Eastern Shore) has the lowest (2.25%). At $100K: a Dorchester/Kent resident pays $4,384 state + $3,082 county ($93,400 × 3.3%) = $7,466 total (7.47%). A Worcester resident pays $4,384 state + $2,102 county ($93,400 × 2.25%) = $6,486 total (6.49%). 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 $7,373 vs VA $4,936, PA ~$3,070 (about $6,070 in Pittsburgh, which adds a 3% local earned income tax), DC ~$5,625. Maryland's combined state+county is higher than VA, PA, and DC alike.
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 | $3,398 (incl. 3.2% county) | $7,218 | $42,782 | 14.4% |
| $75,000 | $7,670 | $5,385 (incl. 3.2% county) | $13,055 | $61,945 | 17.4% |
| $100,000 | $13,170 | $7,373 (incl. 3.2% county) | $20,543 | $79,457 | 20.5% |
| $150,000 | $24,734 | $11,705 (incl. 3.2% county) | $36,439 | $113,561 | 24.3% |
| $250,000 | $51,304 | $20,464 (incl. 3.2% county) | $71,768 | $178,232 | 28.7% |
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 $7,373 (incl. 3.2% county) in state tax alone.

Migration Trends: Maryland has significant two-way migration with its neighbors, especially Virginia, DC and Pennsylvania (DC-area job churn, lower housing costs than DC proper, Baltimore jobs), and with no-income-tax states such as Florida and Texas (retirees and relocations). Virginia's lower tax bill is one reason some commuters choose it: at $100K, Virginia state tax is about $4,936 versus about $7,373 for Maryland state plus county tax. Exact state-to-state migration counts are published by the U.S. Census Bureau (link below).
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, well-regarded public schools in several counties. Why people leave: High taxes (7.37-9.8% combined state+county), high housing costs, better tax deals in VA (5.75% max, no local tax = save $2,437/year at $100K).
Tax considerations: County tax varies 2.25-3.3% (Dorchester/Kent 3.3% highest; Montgomery/Baltimore City among the many counties at 3.2%). Property tax: 0.92% 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: Maryland does not tax Social Security benefits. Nonresidents working in MD generally pay a special 2.25% nonresident tax on top of Maryland state tax, but residents of DC, Pennsylvania, Virginia and West Virginia are generally exempt from Maryland tax on wages earned in Maryland under reciprocal agreements (with an exception for most people who keep a place of abode in Maryland's other state for more than six months and are present there 183+ days). 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 | 2-6.5% + 2.25-3.3% county | $7,373 | Baseline |
| Virginia | 2-5.75% | $4,936 | −$2,437 (save) |
| Pennsylvania | 3.07% + local varies | $3,070 | −$4,303 (save) |
| Delaware | 2.2-6.6% | $5,259 | −$2,114 (save) |
| DC | 4-10.75% | $5,625 | −$1,748 (save) |
Key insight: Maryland's combined state+county tax (7.37% effective at $100K) is higher than VA, PA, and DC alike. At $100K: VA saves $2,437/year, PA saves ~$4,303/year, DC saves ~$1,748/year. At $150K: VA saves $3,894/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 $11,705 total state+county tax (7.80% effective). VA resident pays $7,811 (5.21%). DC resident pays $9,875 (6.58%). Winner: Virginia saves $3,894/year vs MD, ~$2,064/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 (and now DC too) in the DMV region. If you work in DC area, living in Virginia saves $2,400-3,900/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 (2-6.5%). 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: Dorchester County 3.3%, Kent County 3.3%. Most populous counties (Montgomery, Baltimore City, Prince George's, Howard, and most others) sit at 3.2%. Lowest: Worcester County 2.25% (Eastern Shore). At $100K: everyone pays $4,384 state tax (on $93,400 taxable). A Montgomery/Baltimore City resident adds $2,989 county ($93,400 × 3.2%) = $7,373 total (7.37%). A Talbot County (2.4%) resident adds $2,242 county = $6,626 total (6.63%). Nonresidents working in MD generally pay a special 2.25% nonresident tax instead (and residents of DC, PA, VA and WV are generally exempt on Maryland wages under reciprocity agreements).
Virginia saves significant tax. At $100K: VA pays $4,936 state tax (no county tax) vs MD $7,373 state+county = save $2,437/year in VA. At $150K: VA pays $7,811 vs MD $11,705 = save $3,894/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 $2,400-3,900/year at typical salaries). Only choose MD for specific ties (Johns Hopkins, NIH Bethesda campus jobs, Chesapeake Bay waterfront).
Social Security is not taxed by Maryland: taxable federal benefits are subtracted on the state return. Pension/401k/IRA distributions are taxable at the 2-6.5% state rates plus 2.25-3.3% county tax, but taxpayers 65+ (or totally disabled) may qualify for a pension exclusion — the maximum was $41,200 for 2025 and is indexed annually (reduced by Social Security benefits received). Maryland has both an estate tax and an inheritance tax.
State tax (2-6.5%, 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 $4,384 state tax (on $93,400 taxable income). A Montgomery County resident adds $2,989 county tax (3.2% rate) = $7,373 total. A Talbot County resident adds $2,242 county tax (2.4% rate) = $6,626 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 generally pay Maryland state tax + a special 2.25% nonresident tax rather than a county rate (residents of DC, PA, VA and WV are generally exempt on Maryland wages under reciprocity agreements).
Maryland's total burden is higher. At $100K with $450K home: MD pays $7,373 income (state+county) + $4,140 property (0.92% avg) + $3,000 sales (6% avg on $50K) = $14,513 total (14.5%). VA pays $4,936 income + $3,510 property (0.78% avg) + $2,725 sales (5.45% avg) = $11,171 total (11.2%). MD pays $3,342 more/year. Over 10 years: MD pays ~$33,420 more than VA. But: Montgomery County MD schools rank higher than most VA counties (except Fairfax/Loudoun which are comparable). Trade-off: Pay ~$3,300/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 (2-6.5%) PLUS mandatory county tax (2.25-3.3%, no county has $0). The shared calculator engine returns Maryland STATE tax only by default; an optional County / City selector adds that jurisdiction's 2026 local rate to Maryland taxable income (Anne Arundel and Frederick use income-based schedules). The 'state tax' column in the examples table above combines state tax with a 3.2% representative county rate (the rate charged by Montgomery, Prince George's, Baltimore County, Baltimore City, Howard, and several other counties) applied to the same taxable income — a simplification, not a per-county figure. Actual county rates range 2.25% (Worcester, lowest) to 3.3% (Dorchester/Kent, highest), so your real total can differ from these figures by up to about 1 percentage point depending on your county. The $3,400 Maryland standard deduction (per the Comptroller's 2026 withholding guide; the final tax-year 2026 return instructions were not yet published when checked) and the $3,200 personal exemption (reduced at federal AGI above $100,000) are applied before the state and county rates; federal tax is calculated completely separately using the federal standard deduction. Data sources: Maryland Comptroller (2026 state brackets and deductions), this site's own sourced Maryland county tax guide cross-checked against Tax Foundation's confirmation of a 3.3% maximum local rate for 2026 (2026 county-by-county rates), U.S. Census Bureau (migration). Verification: MD's 10-bracket state structure verified against Maryland Tax Code and Comptroller 2026 guidance (2026-09-02). County rate range (2.25%-3.3%) and the 3.2% representative rate verified against sourced county-by-county data (2026-09-03) — see backend/database/fix-maryland-county-tax-2026.js for full sourcing. Limitations: Combined examples use a single 3.2% representative county rate rather than your exact county (see above for the real range). Montgomery County adopted a tiered local rate structure (2.70% / 3.00% / 3.30% by income bracket) effective for tax year 2027 — not modeled here since this calculator uses a single flat 2026 figure. Does not include: MD-specific retirement items (pension exclusion for age 65+; Social Security benefits are not taxed by Maryland), property tax variations (0.93% Montgomery, 2.25% Baltimore City, 0.6-1.5% rural).
