Sales & Use Tax: Official Rates & Who They Are For
The US has no national VAT or GST. Sales tax is governed at the state and local county/city level. In construction and trade contracting, the crucial distinction is between tangible personal property (parts and materials, which are taxable) and labor (which may be exempt for residential capital improvements, but taxable for commercial repairs in states like Texas or Ohio).
