Find the Right Exemption Certificate Path
Start with a state and exemption purpose, then use the official portal and checklist before submitting any certificate.
What is a Resale Certificate?
A resale certificate (or exemption certificate) allows a business to purchase goods tax-free from a supplier, provided those goods will be resold to an end consumer. The end consumer will ultimately pay the sales tax.
As a seller, if you do not collect sales tax on a transaction, you must have a valid exemption certificate on file from the buyer. Otherwise, the state will hold you liable for the unpaid tax during an audit.
