Why the rate here is not the whole story
New York's state rate is 4 percent and Westchester County levies a sales tax of 4 percent on top of it, for a combined 8.375 percent at most addresses in the county once the transportation district surcharge below is added. In New York the state and the counties both levy, and cities may levy as well, but towns and villages may not. Mount Vernon, New Rochelle, White Plains and Yonkers each levy a city sales tax inside Westchester County, and Yonkers is the one that pushes the total above the rest of the county, to 8.875 percent. In the other three cities New York lets the city take over part of the county's rate rather than stack on top of it, so their combined rate matches the county's 8.375 percent even though the split between city and county is different. A further 0.375 percent is collected throughout the Metropolitan Commuter Transportation District, which covers New York City and the counties of Dutchess, Nassau, Orange, Putnam, Rockland, Suffolk and Westchester. That surcharge is neither a state tax nor a county tax, so it is not carried in either rate field and shows up only in the combined figure. Clothing and footwear sold for less than $110 per item are exempt from the state 4 percent everywhere in New York, but Westchester County does not provide the matching local exemption, so the local rate still applies to those sales.
