Why the rate here is not the whole story
New York's state rate is 4 percent and Nassau County levies a sales tax of 4.25 percent on top of it, for a combined 8.625 percent at every address 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. No city in Nassau County imposes a sales tax of its own, so the county line is the tax boundary and one rate applies throughout. 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 Nassau County does not provide the matching local exemption, so the local rate still applies to those sales.
How do I find the exact rate for an address in Nassau County?
