Close the critical items first, then work through the rest. This checklist is a planning aid, not tax advice: confirm treatment of specific items with the Texas Comptroller rules and your tax advisor. ## Content **Intro:** Texas exempts many manufacturing purchases from sales and use tax, but only when the item is used the right way and the paperwork is in order. This checklist walks a plant accountant or controller through registration, purchase classification, utilities, certificates and ERP setup so exempt purchases are supported when the Comptroller asks. **Sections:** #### How to use the checklist **Body:** Work through each group with a copy of your plant equipment list and last year's purchasing report in front of you. Tick items you can prove with a document, not items you believe are true. Mark the critical items first because they are the ones auditors test. Export the result to PDF or Excel and assign an owner and a date to every open line, then re-run it each year or when a new line, building or entity is added. #### What the exemption turns on **Body:** The central question is use. Items that become part of the product, and equipment used directly in making it, are the core of the exemption. Items used before the process starts or after it ends, such as warehousing, administration and sales activity, generally are not. Electricity and natural gas follow a predominant-use test. Because the line between direct and indirect use is fact specific, the checklist pushes you to document the process and review borderline items one at a time instead of exempting whole account codes. **Bullets:** - Ingredient or component of the finished product - Machinery used directly in the manufacturing process - Utilities where manufacturing is the predominant use - Self-assessed use tax on taxable items bought without tax #### Documentation auditors ask for **Body:** A Texas audit typically samples exempt purchases and asks for the certificate, the invoice and a reason the item qualifies. A certificate without a stated reason, signed by the wrong entity or missing a permit number is a common finding. Keep certificates searchable by vendor, keep a short memo for each category of equipment explaining its role in the process, and store the plant flow diagram with it. This turns an audit from a scramble into a retrieval exercise. #### Common mistakes and ERP notes **Body:** The most frequent error is treating a whole purchasing category as exempt because one item in it was. The second is failing to accrue use tax when a vendor does not charge tax on a taxable item, which then shows up as an assessment with interest. In your ERP, give exempt and taxable purchases different tax codes, make the exemption flag part of item setup, and reconcile the use tax accrual account every month. In SAP this is usually a tax code and condition type setup, in Oracle a tax rule or exemption, and in Epicor or SyteLine a tax code assigned on the vendor and item. **Cta:** If your exempt purchase review still lives in spreadsheets, Netray can help read invoices and purchase orders from your ERP and flag likely exempt versus taxable lines for your tax team to approve. **Faq:** #### Does the exemption apply to all equipment in a Texas plant? **Answer:** No. It generally covers equipment and materials used directly in manufacturing, not every asset in the building. Warehouse racking, office equipment and sales or administrative assets are usually taxable. Review items individually and keep documents showing the role of each major machine in the process. #### What certificate do I give my vendor? **Answer:** Texas vendors generally accept the Texas Sales and Use Tax Exemption Certification, Form 01-339, with the exemption reason stated and your permit number filled in. Confirm the current form and instructions on the Texas Comptroller website before issuing certificates to suppliers. #### Do I still owe use tax on exempt purchases? **Answer:** No, if the item truly qualifies. But if a vendor did not charge tax on an item that is not exempt, you owe use tax directly. Your accounts payable process should detect those lines and accrue the tax so it is reported on the Texas return. #### How long should we keep exemption certificates? **Answer:** Keep them for at least as long as the statute of limitations for the related returns plus any open audit period. Texas generally expects records to be kept for four years, but many companies keep certificates longer so they can support multi-year audit sampling. ## Search terms texas manufacturing sales tax exemption, texas manufacturing exemption checklist, texas sales tax exemption manufacturer, texas exemption certificate 01-339, texas manufacturing exemption machinery, texas predominant use electricity manufacturing, texas use tax manufacturing equipment, texas sales tax audit manufacturer --- Talk to an engineer: https://netray.co/contact?intent=erp_ai | Machine catalog: https://netray.co/agent/catalog.json
