A use tax is a type of tax levied in the United States by numerous state governments. It is essentially the same as a sales tax but is applied not where a product or service was sold but where a merchant bought a product or service and then converted it for its own use, without having paid tax when it was initially purchased. Use taxes are functionally equivalent to sales taxes. They are typically levied upon the use, storage, enjoyment, or other consumption in the state of tangible personal property that has not been subjected to a sales tax.
