Privacy controls for Form ST-587
Personal taxpayer identification details may remain visible in completed certificates shared through unsecured email or broad-access folders. Missing electronic-consent records can make it difficult to demonstrate that a signer agreed to receive and sign the certificate digitally. Unrestricted workspace permissions may expose completed Illinois tax exemption certificates to employees without a business need. Duplicated templates can preserve outdated purchaser details, creating accidental disclosures when certificates are sent to vendors.
Risks from incomplete certificates
Seller rejects certificate
Tax treatment disputed
Certificate lacks execution
Audit evidence weakened

Form ST-587 troubleshooting
Resolve field, signing, plan, and recordkeeping questions before delivering an Illinois exemption certificate to a seller.
Upload the current Illinois PDF rather than relying on an old saved copy. In signNow, review auto-detected fields, compare them with the printed certificate, and add required fields manually before sending. The platform’s audit trail records later changes and signing activity.
The Business plan includes templates, audit trails, and mobile apps at $8 per user per month when billed annually. Business Premium is $15 and adds bulk send. Choose based on the number and routing pattern of certificates, not the form name.
Use signNow’s signer authentication options, including SMS OTP where configured, and retain the event history with the signed PDF. ESIGN and UETA recognize electronic signatures when intent, consent, attribution, and record reproduction are established.
A completed certificate should be paired with its audit trail and transaction record. Export both from signNow, restrict access to authorized personnel, and apply the organization’s Illinois tax-record policy; the form itself does not establish a universal retention period.
If a purchaser cannot sign electronically, download the prepared certificate and follow the seller’s accepted process. Do not represent a missing signature as completed. Electronic-record consent and access requirements may apply under ESIGN, especially for consumer-facing transactions.
Business Premium includes bulk send, while the Business plan does not include that feature according to the signNow plan details. For a small number of Illinois certificates, send individually and verify each purchaser’s transaction-specific fields before delivery.
