Challenges when completing Form 599
Incomplete taxpayer identification or return-year information can make the copy request difficult to match to the correct income tax return. A missing signature, date, or authorization statement may delay review because the recipient cannot confirm the requester’s authority. Sending the request to an unverified email address can expose sensitive tax information and create a disclosure-control problem. Saving the signed form without its audit trail can weaken evidence of signer identity, consent, timestamps, and document history.

Upload the original Form 599 PDF again, then review signNow’s detected fields manually. Auto-detection can identify fillable areas, but the sender remains responsible for confirming taxpayer names, return details, authorization fields, and signature placement before sending.
Open the recipient settings and confirm the signer’s email address. Resend the invitation or generate a controlled signing link. If stronger identity evidence is required, configure SMS authentication where available and retain the resulting audit trail with the completed request.

ESIGN and UETA generally recognize electronic signatures when intent, consent, attribution, and record retention are established. Confirm the tax-record custodian accepts an electronically signed Form 599 before relying on signNow as the submission method.
