Sales tax is jurisdiction-specific
Sales tax rules vary by state, and within New York, by county and city. Whether a transaction is taxable depends on the type of product or service, the location of the sale, and the nature of the buyer. These guides provide general educational information focused primarily on New York.
Sales tax questions that involve multiple states, complex product classifications, or significant back-tax exposure benefit from professional review. The rules are specific enough that general guidance has real limits.
