If a contractor moves its fabrication work into a single-member LLC that elects to be taxed as a corporation, does the new entity qualify as a manufacturer for Tennessee's industrial-machinery and business tax exemptions?

When a manufacturer expands a factory, which of the new machinery, structural components, electrical systems, and pollution-control equipment qualify for Tennessee's industrial machinery sales tax exemption -- and which count as part of the building instead?

If a company sells compressed air (not the compressor itself) to a manufacturer under a long-term service contract, does the sale qualify for Tennessee's industrial machinery sales tax exemption?

A Tennessee manufacturer buys design software with a bundled maintenance plan, plus a long list of welding gases, gear, and shop supplies -- which of these qualify for the sales tax industrial machinery or industrial materials exemptions?
It's a mixed bag by item. The design software (and its bundled maintenance contract) is FULLY TAXABLE -- because it's used before raw materials reach the manufacturing process, it doesn't count as "ne…
When a company operating a Tennessee qualified data center expands its facilities with a new round of investment, does it qualify again for the headquarters-facility sales/use tax credit, and can it keep using its existing industrial machinery exemption certificate for the expansion?
Yes to all four questions, assuming statutory requirements are met. The Department ruled that the Taxpayer's planned facility expansion will be treated as a new 'qualified headquarters facility' under…
For a company that runs on-site photocopy and fax centers under a management-fee contract, which equipment and supplies qualify for the industrial machinery sales tax exemption, and must sales tax be charged on the full contract price?

Are the reusable wooden patterns a metal casting foundry uses to make sand molds exempt from Tennessee sales and use tax as industrial machinery, even though the patterns never directly touch the finished metal casting?
