Instructions

This exemption certificate is to be completed by the purchaser claiming exemption from tax and given to the seller. The seller must retain this certificate as proof that exemption has been properly claimed. The certificate must be complete to be accepted by the seller. The seller can accept an exemption certificate only on property that is qualified (see the exemptions below) or based on the nature of the buyer. If property or services purchased for resale or processing are used or disposed of by the purchaser in a nonexempt manner, the purchaser is then responsible for the tax.

What the Exemption Certificate Sales 2018 2019 covers

The Exemption Certificate Sales 2018 2019 is a seller-side form used to document a buyer's claim of sales tax exemption for transactions occurring during tax years 2018 and 2019. It records the buyer's exemption reason, statutory basis, and identifying information so the seller can justify non-collection of sales tax. Proper completion supports seller recordkeeping, reduces audit risk, and establishes the factual basis for exempt sales when reviewed by state departments of revenue or auditors.

Why accurate exemption certificates matter

A complete Exemption Certificate Sales 2018 2019 protects sellers from failing-to-collect liability, supports correct reporting to state tax authorities, and documents buyer entitlement to exemption under state law. It also aids internal controls and audit readiness while clarifying the taxable status of past transactions.

Why accurate exemption certificates matter

Who completes and relies on this certificate

Sellers and their tax/accounting staff prepare and retain certificates; buyers provide the information and attest to exemption eligibility.

  • Retail and wholesale sellers — Keep certificates on file to justify tax-exempt sales.
  • Accounts payable teams — Collect and validate buyer attestations before payment or shipment.
  • Tax professionals — Use certificates to substantiate positions for state audits and returns.

Maintain copies with sales records and match certificates to invoices to support tax positions during audits.

Step-by-step: Completing the Exemption Certificate

Follow this sequence to collect, verify, and file the certificate for transactions in 2018 and 2019.

  • 01
    Collect information: Request buyer name, address, exemption number, and reason.
  • 02
    Verify exemption: Confirm resale or exemption number with state lookup where available.
  • 03
    Obtain signature: Have an authorized buyer sign and date the form.
  • 04
    File and index: Attach to invoice and store in searchable records for audit.

Typical workflow for handling exemption certificates

This flow shows how certificates move from collection to retention within seller systems.

  • Request: Buyer receives certificate request at order or onboarding.
