Intermediate Quick Answer
What R&D and manufacturing exemptions exist, and how do I qualify?
⚡ TL;DR
Most states exempt machinery, equipment, and materials used directly in manufacturing, but the 'direct use' standard varies significantly by state. R&D exemptions are narrower and available in only a minority of states, including California and Texas. Both require an exemption certificate from the buyer specifying the manufacturing or R&D exemption reason.
Most states exempt manufacturing inputs; R&D exemptions exist in fewer states and are generally narrower. Both require the buyer to provide an exemption certificate claiming the applicable reason.
Key takeaways
- Manufacturing machinery and equipment: exempt in most states; the buyer must use the equipment directly in the production process: the “direct use” standard varies significantly by state
- Raw materials and inputs: materials incorporated into the manufactured product are broadly exempt; consumables (lubricants, molds, packaging used in production) often exempt; administrative supplies are not
- Electricity and fuel used in manufacturing: many states exempt these when used directly in the production process; some states exempt only a portion
- “Direct use” vs. “used in the process” test: states are split: the narrower direct-use test (physical contact with the product) is more common in the South; broader “used in the process” standards cover more equipment in states like TX and CA
- R&D exemptions: available in a minority of states; CA exempts purchases for qualified research under IRC §41; TX has an R&D exemption for equipment and materials used directly in qualified research; most states do not have a standalone R&D exemption
- Seller’s role: collect and retain an exemption certificate from the buyer claiming the manufacturing or R&D exemption; verify that the certificate identifies the specific exemption reason, don’t accept a generic resale certificate for manufacturing claims
- Common audit issue: buyers overapply manufacturing exemptions to equipment not directly used in production (break room appliances, janitorial equipment, office computers) — sellers aren’t liable if the certificate was accepted in good faith, but buyers may face use tax assessments
Frequently asked questions
Are manufacturing inputs exempt from sales tax?
In most states, yes, machinery, equipment, and materials used directly in manufacturing are exempt from sales tax. The scope of 'directly used' varies by state. Some states require a direct physical contact test (the item must directly touch or transform the manufactured product). Others use a broader 'used in the process of manufacturing' standard that covers more equipment. Fuel, electricity, and raw materials consumed in manufacturing are also often exempt. A manufacturing exemption certificate is required from the buyer.
Are R&D purchases exempt from sales tax?
Some states exempt purchases used in qualified R&D, but the exemptions are generally narrower than manufacturing exemptions. States that have R&D exemptions (including CA, TX, and a few others) typically limit them to equipment and materials directly used in qualified research, not office supplies, computers used for general business, or administrative expenses. The buyer must document the R&D use and provide an applicable exemption certificate.
