Construction contracts or contracts for reconstruction, alteration, expansion, or remodeling with equipment sales, commonly known as mixed contracts, place a dual burden on the contractor, as a contractor is a consumer of construction materials and also a retailer of the machinery and equipment.
EXAMPLE: Company A contracts with Company B to have Company B build a new building and install all of the production machinery and equipment for the new building. Company B must pay tax on its purchases of building materials and supplies that lose their identity as tangible personal property and become a component part of the real property. Company B also purchases some refrigeration units for the new building that maintain their identity as tangible personal property. These units must be purchased tax-free by Company B because they will be resold. Company B would then charge Company A the tax on the units that retain their identity as tangible personal property. The installation charges for the units that remain as tangible personal property would be part of the total sales price subject to tax unless they are separately contracted or, if no written contract exists, are separately itemized on the billing from Company B to Company A. If the installation charges involve the performance of one or more enumerated services, they would be subject to sales tax even when separately contracted for or separately itemized on the billing from Company B to Company A.
