Thanks to the DC–Maryland–Virginia Tri-Jurisdiction Income Tax Reciprocity Agreement, a federal official, defense executive, or K Street partner working in downtown Washington, D.C. pays income tax exclusively to the jurisdiction where they live—never where their office is located. Because crossing the Potomac River into Arlington or McLean, Virginia caps your top marginal state income tax rate at 5.75%—compared with 8.95% in Bethesda/Montgomery County, Maryland (5.75% state + 3.20% county piggyback) and 9.25%–10.75% in Washington, D.C.—choosing the right side of the Capital Beltway saves high-earning households $10,000 to $25,000 every single year.
NYC & NY State Paycheck & Hourly Wage Tax Calculator (2026)
Calculates Federal withholding, FICA (Social Security + Medicare + 0.9% surtax), NY State progressive brackets (4%–10.9%), and NYC resident tax (3.078%–3.876%) for both annual salaries and hourly wages.
How DC–MD–VA Commuter Tax Reciprocity Works
Unlike the New York–New Jersey corridor (where NJ commuters must file NY non-resident returns on Form IT-203), Washington, D.C., Maryland, and Virginia maintain full wage reciprocity. If you live in McLean, Arlington, or Alexandria, Virginia and commute across the Key Bridge into a D.C. or Bethesda office, your employer withholds only 5.75% Virginia state income tax ( filing Form D-4A exemption in D.C.). You never pay D.C.’s 8.50%–10.75% upper brackets or Montgomery County’s 3.20% local piggyback tax.

The Northern Virginia Personal Property Car Tax vs. DC’s Low 0.85% Homeowner Property Tax
While Virginia wins overwhelmingly on income taxes above $200,000, Washington, D.C. offers the lowest residential real estate tax rate in the region: 0.85% on the first $2.5 million of assessed value (minus the $87,050 DC Homestead Deduction), compared with 1.03% in Arlington County and 1.125% in Fairfax County. Additionally, Virginia counties levy an annual Personal Property Vehicle Tax (“Car Tax”) of $4.15 to $4.57 per $100 of NADA/JD Power trade-in value ( costing ~$2,200/year on a $65,000 luxury SUV after partial PPTRA relief), whereas D.C. and Maryland charge $0 in annual vehicle property tax.
