Do you charge sales tax on labor in OK?

Most of the time labor must be itemized separately for you not to be charged sales tax. In cases like where a contractor puts a new roof on a home for $8,000 then sales tax must be charged for the whole amount. If the invoice lists the bill of $4500 for materials and $3500 for labor to put on new shingles then sales tax would only be charged for the material and not for the labor. This is pretty much the law in just about every state.
