Question: When are my purchases sales tax exempt? How do I let my vendors know?

Answer: By completing an exemption certificate you will need to answer specific questions regarding what the purchase is for.  If the purchase is for resale-you will also need a seller’s permit and will need to provide your vendor with an exemption certificate. When in doubt, always contact WDR with specific questions.
