Run Commercial Account Tax Exemption Certificate Audit — Free

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 critical (required)

Verify that at least one executed certificate exists in the document management system or physical file.

Yes No N/A

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.

Yes No N/A

Certificate is legible and complete (no missing fields, signatures, or pages) critical (required)

Review the document for completeness: buyer name, seller name, state, exemption reason, authorized signature, and date must all be present.

Yes No N/A

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 critical (required)

Confirm the certificate has not passed its state-mandated expiration date. A sale made on an expired certificate is taxable and creates seller liability.

Yes No N/A

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.

Yes No N/A

Certificate covers the current tax period for all recent exempt transactions critical (required)

Verify that the certificate was valid and on file at the time of each exempt sale — not obtained retroactively after the transaction.

Yes No N/A

Certificate Accuracy & Business Alignment

Buyer name on certificate matches the legal business name on the account critical (required)

The name on the certificate must exactly match the legal entity making the purchase. DBAs or subsidiaries require separate certificates.

Yes No N/A

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.

Yes No N/A

State on certificate matches the state where the sale/delivery occurs critical (required)

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.

Yes No N/A

Exemption reason stated on certificate

Select the exemption basis claimed on the certificate.

Exemption reason is consistent with the account's actual purchasing activity critical (required)

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.

Yes No N/A

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.

Yes No N/A

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 critical (required)

Cross-reference transaction dates against certificate effective and expiration dates. Flag any exempt sale made before the certificate was received.

Yes No N/A

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.

Yes No N/A

Deficiency Resolution & Corrective Actions

Overall certificate compliance status for this account

Select the outcome of this audit for the account.

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.

Yes No N/A

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.

Yes No N/A

Auditor certifies that this review was conducted accurately and all findings are documented.
