How the Taxes Work
Greenwich and Stamford are home to finance professionals, hedge fund managers, and executives who commute 45–60 minutes to Midtown. The tax situation is favorable compared to being an NYC resident.
Fairfield County (Stamford, Greenwich, Darien, Westport) is the quintessential NYC commuter belt. CT residents avoid NYC's local income tax while benefiting from CT's credit for NY taxes paid.
The critical distinction is NYC residency. New York City imposes a local income tax ranging from 3.078% to 3.876% on city residents. This tax does not apply to people who merely work in NYC — it applies only to those who live there. As a result, any commuter living outside the five boroughs is automatically exempt, regardless of how many hours they spend in a Manhattan office.
