What Are Exemption and Resale Certificates?

• Exemption Certificates: For buyers with tax-exempt status or qualified purchases; used to document tax-free transactions.

The following table provides an overview of the differences between the certificates:

• Tax Liabilities and Penalties: Sellers may owe unpaid taxes, plus penalties of up to 25% and ongoing interest for noncompliance.
• Lengthy Audits: Issues often lead to audits spanning multiple periods, consuming staff resources and time
