Commercial Account Tax Exemption Certificate Audit

Verifies each tax-exempt commercial account has a current, valid resale or exemption certificate on file, aligned with the account's state of operation and within the applicable renewal window. Supports compliance with state sales tax exemption rules and reduces exposure to audit penalties.

Account Identification & Audit Setup

• Account name (legal business name)
  Enter the full legal business name as it appears on the exemption certificate.
• Account number / Customer ID
  Internal account or customer ID from the ERP or billing system.
• State(s) in which exemption is claimed
  List all states for which this account has submitted an exemption certificate. Each state certificate must be reviewed separately.
• Audit date
  Date this certificate audit is being conducted.
• Auditor name and title
  Full name and title of the person conducting this audit.

Certificate Existence & Document Control

• A signed exemption or resale certificate is on file for this account
  Verify that at least one executed certificate exists in the document management system or physical file.
• Certificate form type on file
  Select the type of exemption document on file for this account.
• Certificate is stored in the designated document repository (e.g., ERP, DMS, shared drive)
  Confirm the certificate is filed in the approved, auditable storage location — not solely in email or an individual's local drive.
• Certificate is legible and complete (no missing fields, signatures, or pages)
  Review the document for completeness: buyer name, seller name, state, exemption reason, authorized signature, and date must all be present.

Certificate Validity & Currency

• Certificate issue date (or effective date)
  Date the certificate was signed or issued by the buyer.
• Certificate expiration date (if state-mandated)
  Enter the expiration date if the issuing state requires one. Leave blank if the state issues perpetual certificates.
• Certificate is NOT expired as of the audit date
  Confirm the certificate has not passed its state-mandated expiration date. A sale made on an expired certificate is taxable and creates seller liability.
• Days until certificate expiration
  Enter the number of days remaining before expiration. Enter 9999 if the certificate is perpetual/no expiration date.
• Certificate renewal has been initiated (if expiring within 60 days)
  If expiration is within 60 days, confirm that a renewal request has been sent to the customer and is documented.
• Certificate covers the current tax period for all recent exempt transactions
  Verify that the certificate was valid and on file at the time of each exempt sale — not obtained retroactively after the transaction.

Certificate Accuracy & Business Alignment

• Buyer name on certificate matches the legal business name on the account
  The name on the certificate must exactly match the legal entity making the purchase. DBAs or subsidiaries require separate certificates.
• Seller name on certificate matches our company (or is left blank per state rules)
  Some states require the seller's name; others allow blanket certificates. Confirm the certificate is valid for purchases from this company.
• State on certificate matches the state where the sale/delivery occurs
  A certificate issued in State A does not automatically exempt a sale delivered to State B. Multi-state accounts need certificates for each applicable state.
• Exemption reason stated on certificate
  Select the exemption basis claimed on the certificate.
• Exemption reason is consistent with the account's actual purchasing activity
  Example: A resale certificate is only valid if the customer is actually reselling the purchased items. Purchases for internal use or consumption are taxable even if a resale certificate is on file.
• Account's state business registration / tax ID number is recorded and matches the certificate
  Verify the state sales tax permit number or EIN on the certificate matches the account's registration on file. Invalid or fictitious permit numbers invalidate the exemption.

Transaction Sampling & Exemption Application

• Number of exempt transactions reviewed in this audit sample
  Enter the count of individual transactions reviewed. Minimum recommended sample: 5 transactions or 10% of annual exempt transactions, whichever is greater.
• All sampled transactions were coded as exempt only during a period when a valid certificate was on file
  Cross-reference transaction dates against certificate effective and expiration dates. Flag any exempt sale made before the certificate was received.
• No sampled transactions include item categories that are taxable regardless of exemption status (e.g., meals, lodging, personal-use items)
  Some product categories are taxable by statute even when the buyer holds a valid exemption certificate. Confirm exempt coding was applied only to qualifying items.

Deficiency Resolution & Corrective Actions

• Overall certificate compliance status for this account
  Select the outcome of this audit for the account.
• Deficiencies identified (describe each)
  List each deficiency found: missing certificate, expired certificate, name mismatch, wrong state, invalid permit number, retroactive certificate, etc.
• Corrective action assigned and owner documented
  Confirm that each deficiency has an assigned owner, a corrective action, and a target resolution date documented in the account record.
• Account flagged in billing system to suspend exempt coding until deficiency is resolved (if Major Deficiency or On Hold)
  If a major deficiency exists, confirm the account's tax-exempt flag has been suspended in the ERP/billing system to prevent further unprotected exempt sales.
• Auditor signature
  Auditor certifies that this review was conducted accurately and all findings are documented.
